YouTube's new 'nocookie' feature continues to serve cookies

by Chris Soghoian

Responding to criticism from privacy activists, YouTube in the past two weeks has rolled out a number of new privacy features. Chief among these is a "delayed cookie" option thatYouTube promises will not leave cookies in the browsers of users who have not yet clicked the "play" button to view a video.

While this statement is true for traditional Web browser-based cookies, YouTube's cookie-lite solution still leaves long-term, non-session Flash cookies behind in the Web browser of visitors who have yet to actually click play to watch the YouTube videos.

As revealed on this blog yesterday, YouTube has recently rolled out a number of new privacy features, chiefly in response to privacy activists complaining about the company's use of non-session cookies.

Writing on the Google corporate policy blog Tuesday, Steve Grove of YouTube stated:

To ensure that we openly communicate about privacy issues on all federal websites that use our technology, we created an embeddable video player that does not send a cookie until the visitor plays the video.

YouTube's online technical documentation also reveals a bit more about the feature:

Enabling delayed cookies means that the YouTube video player will not set any non-session cookies on the computer of a visitor (viewing the page on which the YouTube video is embedded). The YouTube video player may set non-session cookies on the visitor's computer once the visitor clicks on the YouTube video player.

While this statement is true for browser-based permanent cookies, it is still a false statement. Visitors to Web pages that have made use of this new cookie-lite feature continue to receive long-lasting Flash cookies, even when they do not click play to watch a video.

The Electronic Privacy Information Center has thoroughly described the Flash cookie privacy problem:

Flash cookies provide the only method by which a flash movie can store information on a user's computer....

Few consumers are aware of where Flash cookies are stored or how to control their use. Normal web cookies can be managed via the preferences dialog of most web browsers, but no similar utility is included for these Flash cookies. It is possible for Flash cookies to remain on user's computer indefinitely, as there is no mechanism to set an expiration date on Flash cookies.

The only way to delete these well-hidden objects is to visit a special Web page on Adobe's site. The existence of Flash cookies and the need to visit the special Adobe Web site to remove them is not widely known by most Web users.

Web browsers are unable to automate the process of Flash cookie removal. As a result, those in the security community have had to take rather extreme steps to try to automate the process of Flash cookie removal in a way that doesn't break most Web functionality. These obscure techniques remain far too advanced for non-technical users.

Proof of YouTube's use of Flash cookies
To verify that YouTube is still using non-session cookies, follow these steps:

  • First, go to the Adobe Flash Settings Manager page, and delete all of your old Flash cookies.

  • Close all of your browser tabs, and restart your browser. Now revisit the Adobe Flash Settings Manager page, and verify that you still have no Flash cookies.
  • Then, go to a Web page that is making use of the new YouTube "delayed cookies" feature. For this example, we used Barack Obama's inaugural address, as embedded into one of the older White House blog entries.



    (As we noted on this blog yesterday, the White House used an in-house Flash based tool for its latest weekly video address. Earlier messages from the President are still delivered using YouTube, although the White House tech team has enabled the "delayed cookie" option for all of these).

  • By looking through the source code for that blog page, we can verify that the YouTube flash file is indeed being served from youtube-nocookie.com, and thus should be making use of the "delayed cookie" feature.



    <script type="text/javascript">
    	var params = { allowscriptaccess: "always", allowfullscreen: "true" };
    	swfobject.embedSWF("http://www.youtube-nocookie.com/v/3PuHGKnboNY&hl=en&fs=1&showinfo=0",
    
            "flashcontent", "480", "295", "8", null, {}, params);
    </script>
    

  • Wait for the YouTube flash file to load, but do not click play. Now, close all your browser tabs, and then restart the browser.
  • Remember that session-cookies, by definition, are for a single browsing session, and thus when you restart the browser, all previous session cookies are deleted. Anything still hanging around is long-term.
  • Now, go back to the Adobe Flash Settings Manager, and you should see that a cookie from s.ytimg.com (a domain controlled by Google) has now been quietly added to your Flash cookie jar, even though the White House Web site made use of the "delayed cookie" option, and you never clicked the play button.

Analysis
Those in the privacy community will likely pounce on this as evidence of Google's hypocrisy, while Google will likely respond by carefully parsing the definition of the phrase "non-session cookie" to not include Flash-cookie objects. Google might even even argue that its Flash-based cookies do not contain unique tracking information (something this blogger is unable to verify, since the Adobe Flash Manager only allows you to delete, but not view the contents of a Flash cookie).

One thing is clear. YouTube has advertised a new delayed cookie feature, and stated that it "does not send a cookie until the visitor plays the video." That message is further reinforced by the fact that the new cookie-lite embedded video players are served from a different domain name, youtube-nocookie.com.

Yet a user visiting a page that includes one of these "delayed cookie" videos still ends up with a long term, non-session Flash cookie hidden away in the depths of their browser.

Technical definitions of "cookie" versus "Flash cookie" aside, YouTube's "delayed cookie" feature simply fails to deliver on the company's promises.

When reached for comment, Marc Rotenberg, the director of the Electronic Privacy Information Center, said:

(Regarding the) spat over cookies, the Youtube and the Whitehouse web site is the tip of the iceberg. There is a much bigger debate about Google's role in federal information policy looming.

The Google blog post, if read carefully, is very revealing. It is all about justifying Google's growing dominance in government information dissemination.

This is a business plan. It is tied directly to YouTube's advertising model and revenue forecasts. There is nothing about actual federal information policy.

Complying with federal laws (e.g. the Privacy Act which regulates data collection) or federal policy on persistent cookies are real obstacles. The question is whether Google will decide for itself whether it will comply with these laws or the people's representatives.

The debate is just beginning.

Google's PR team have yet to respond to queries from this blogger regarding the cookie issue.

Is the White House changing its YouTube tune?

Editors' note: Correction, March 3, 12:46 p.m. PST: This post, which originally carried the headline "White House ditches YouTube after privacy complaints," significantly misconstrued the White House's policy on and use of YouTube. In the interests of disclosure and transparency, we are leaving the contents as originally posted, with two subsequent update notes and with the exception of the headline change. See also our follow-up story, "No, the White House hasn't ditched YouTube."

* * * * * * * * * * * * * Original story follows * * * * * * * * * * * * *

Updated at 5:50 p.m. PST March 2: The New York Times is reporting that the White House has denied any change in online video policy. While the White House spokesperson admitted to using an in-house flash based solution for the latest of the president's weekly video messages, he said the White House is just "experimenting" with different solutions.

Updated at 2:59 a.m. PST March 3: Late Monday, Google posted on its Public Policy Blog a rebuttal to this report: "White House videos on YouTube."

Responding to complaints by privacy activists, the White House has quietly abandoned YouTube as the provider of the embedded videos on the president's official home page.

With the release of the latest weekly video address, the White House has shifted to a Flash-based video solution using Akamai's content delivery network.

The White House's decision to move away from the Google-owned video-sharing site will likely be met with praise by privacy activists and could mark the beginning of a real backlash in response to Google's insatiable thirst for detailed data on the browsing habits of Web surfers.

Ironically, the decision by the White House comes days after YouTube began to roll out new policies to better protect the privacy of visitors who view videos embedded into federal government Web sites. The move by YouTube may prove to be too little, too late.

This is the new embedded video tool used by the White House.

The White House's decision to embed YouTube videos in the president's official home page drew instant criticism from privacy activists. In addition to several critical posts on my blog, by the Electronic Frontier Foundation (here and here), the Center for Democracy and Technology and the Center for Digital Democracy blasted the choice of video providers.

The focus of the criticism was on the use of long-term tracking cookies by the Google-owned video-sharing site. When the new White House site first went live in January, every visitor to the president's blog would be issued a tracking cookie, even those who did not click the "play" button to watch the video.

The White House acted quickly, and soon deployed a technical fix to the cookie issue, which protected Web surfers who did not click the play button. However, the tens of thousand of people who clicked play were still issued a cookie, and thus tracked by YouTube.

In an unannounced change over the weekend, the White House appears to have solved the remaining cookie privacy issue for those Web site visitors who wish to watch the president's weekly video message.

Out with YouTube, in with Akamai
As of Saturday, the White House seems to have ditched YouTube as its video provider. Visitors to the White House blog can now click play to view a Flash-based video that loads directly from the White House's own Web servers. This solution, which appears to use Akamai's content delivery network, does not make use of tracking cookies.

The president's tech team seems to have finally hit on an optimal solution--one which protects the privacy of the visitors to the White House site, while still permitting the president to spread his message.

The White House is still posting copies of the videos to its official YouTube channel. However, the president no longer provides free advertising to YouTube by embedding those videos on a taxpayer-funded site.

Furthermore, the White House has copied one of the coolest of YouTube's social features: the ability for users to easily share and embed videos on their own sites. Each of the White House-hosted videos includes an "embed" link under it that can be copied and pasted onto any other Web site or blog.

It is unclear whether this switch away from YouTube marks a permanent shift in policy for the White House, or whether the Oval Office geek squad is merely testing an alternate video provider. While the latest video is served using Akamai's servers, the older videos remain as embedded YouTube files.

YouTube's new cookie rules
The timing of the White House's decision to switch to Akamai is rather strange, given the recent moves by YouTube to offer a more privacy-preserving solution for videos used on federal government sites.

Within the last couple weeks, YouTube has silently rolled out its own updates in response to the cookie-related criticism. People wishing to embed a YouTube video can now select a delayed cookies option when copying the embed URL.

This is the new delayed cookies option for YouTube embeds.

That choice will cause the embedded videos to be served from an alternate domain, www.youtube-nocookie.com, which registrar records reveal was first registered on January 23 2009, just one day after this blog first mentioned the White House/YouTube cookie issue.

New documentation on the YouTube site reveals:

Enabling delayed cookies means that the YouTube video player will not set any non-session cookies on the computer of a visitor (viewing the page on which the YouTube video is embedded). The YouTube video player may set non-session cookies on the visitor's computer once the visitor clicks on the YouTube video player.

This option is rather similar (yet still inferior) to the technical fix that was previously used (and since disabled) by the White House, as well as the open source MyTube tool developed by the Electronic Frontier Foundation.

A prominent privacy policy
In another new move by YouTube, the site now appears to be directly embedding a link to its privacy policy in all videos that are played from government sites.

This is the new privacy policy link in .gov-hosted YouTube videos.

(Credit: Whitehouse.gov)

When those same videos are viewed at YouTube.com, or when embedded in a blog or other non-.gov site, the clickable link to the privacy policy is gone.

Webmasters for various state agencies seemed to notice the new policy last week and initially complained to YouTube, thinking that the new youtube-nocookie.com was a phishing site.

A representative from YouTube told the Webmasters:

The privacy policy link you see on your embed player is in response to federal regulations regarding privacy on embed players. We're working to remove it from state and local .gov sites as soon as possible.

Still not perfect
While the decision by the White House to ditch YouTube is a good one, unresolved issues remain.

First, as previously noted by the Electronic Frontier Foundation, the White House Web site makes use of an "invisible pixel" style Web bug/tracker on every page on the site, hosted by WebTrends.com.

Ideally, the White House should take its Web analytics technology in-house and abandon the use of this third party tracking technology. Otherwise, at the very least, the White House privacy policy should be updated to note the tracking cookies used by WebTrends.

Second, the White House still has not published the waivers it issued to YouTube (and potentially other third parties), which permitted the sites to use long-term tracking cookies. The Electronic Frontier Foundation has repeatedly asked for these documents-- requests that the White House has ignored.

Given the president's much-publicized commitment to transparency, it is time that the White House publishes these documents.

Third, in its recent move to include privacy policy links in videos embedded at .gov Web sites, YouTube has clearly demonstrated that it has the ability to modify the services it provides depending on the referrer information associated with incoming requests. YouTube should build on this and adopt a policy of not logging any data associated with .gov-referred requests.

That is, the site would be free to keep logs on the videos viewed by visitors to its own site as well as those embedded on blogs, but it would opt to immediately forget all identifying information associated with requests from government sites.

While the White House seems to understand the cookie privacy issue, it is unlikely that members of the House and Senate are equally as tech savvy. After all, some of them can barely figure out Twitter.

YouTube videos are heavily used on the Web sites of those in the House and Senate. YouTube should adopt sane logging policies for visitors who view these videos, so that we don't have to wait for the House and Senate to fix the problem themselves.

YouTube did not return a request for comment, while a representative for the White House Web team declined to speak on the record.

White House acts to limit YouTube cookie tracking

by Chris Soghoian
  • 4 comments

Just 12 hours after this blog highlighted the privacy problems associated with the White House's use of embedded YouTube videos, the Obama team rushed to deploy a technical fix that significantly protects the privacy of many (but not all) of the site's visitors.

Since its launch three days ago, President Obama's White House Web site has included several embedded YouTube videos. While this certainly demonstrates that the 44th president is Web 2.0 savvy, the decision to embed YouTube videos has also enabled the Google-owned video-sharing site to sneakily collect data on the millions of people who visit Whitehouse.gov--even those users who never click the "play" button to actually watch one of the videos.

Change.gov, the Web site for the Obama/Biden transition team, also made extensive use of YouTube videos. This practice was something that I sharply criticized back in November, citing the cookie-related privacy risks as well as the decade-old rules prohibiting the use of long-term tracking cookies on federal agency Web sites.

Unfortunately, when the new White House Web site launched, rather than fix the privacy issues that had plagued the transition team's Web site, Obama's legal team instead opted to provide YouTube with an exemption to those pesky federal regulations, letting it use long-term cookies to track visitors to the White House Web site. No other company was singled out and granted such a waiver.

It seems that someone in the White House read my blog post yesterday--as within 12 hours of the story going live, Obama's Web team rolled out a technical fix that severely limits YouTube's ability to track most visitors to the White House Web site.

By late Thursday evening, each embedded YouTube video had been replaced with an image of a video player, which a user must click on before the real YouTube player will be loaded. The result of this change is that YouTube is now only able to use cookies to track users who click on the "play" button on an embedded YouTube video--the majority of people who scroll through a page without clicking play will not be tracked.

This is clearly a step in the right direction--and it is particularly interesting to see that the White House has essentially rolled their own version of the Electronic Frontier Foundation's MyTube privacy tool.

While this is great news (especially after just a few hours), it is by no means a comprehensive solution, but a Band-Aid. Those users who do click the "play" button will be secretly tracked as they navigate the White House Web site--and if those users have visited YouTube or any other Google-run Web site in the past, the fact that they watched an Obama video will be added to the existing massive pile of data the company has compiled on each of them.

Simply put, there is no good reason for Google to be able to data mine a citizen's interaction with the president--especially when watching a video that was produced and uploaded by the White House at the taxpayers' expense.

The White House is already making use of Akamai's commercial edge caching services, and the transition team made full use of Amazon's Simple Storage Service for the download-friendly version of Obama's weekly address. Rather than using YouTube, the State Department has for some time opted to pay for a commercial, flash-based video streaming solution provided by Brightcove for its propaganda information site America.gov.

If the Obama team is willing to pay for some of its Web 2.0 technology, why can't they also follow the State Department's lead and cough up a few bucks for a streaming video service that doesn't cross-subsidize its offerings by tracking the Web habits of users.

Finally, if the White House lawyers are going to waive long-standing federal privacy rules for YouTube, merely mentioning the existence of that waiver is not enough. Given Obama's much publicized commitment to transparency, I think it's quite reasonable to ask that the team post the text of each and every waiver to the federal cookie policy to its Web site. Members of the public have a right to know the reasons that were used to justify exempting YouTube's cookies from these otherwise strict rules. If the YouTube waiver cannot withstand the analysis of legal experts and the ridicule of tech bloggers, it probably shouldn't have been authorized.

The White House Web site has been live for just three days, and in just the past day, Obama's administration has given us some reason to believe that it takes Web privacy seriously. Over the next few weeks, it'll have a chance to prove it.

White House exempts YouTube from privacy rules

by Chris Soghoian
  • 15 comments

Update: 12 hours after posting this story, the White House (partially) reversed itself. The rather dubious YouTube-only waiver from federal Web privacy rules has been maintained, but the White House Web site has been updated to limit the exposure of visitors to YouTube's tracking efforts to only those people who actually click the "play" button on a YouTube video. For more details on the new changes, read this blog post.

The new Web site for Obama's White House is already drawing attention from privacy activists and tech bloggers. While the initial focus has been on the site's policies relating to search engine robots, a far more interesting tidbit has so far escaped the public eye: the White House has quietly exempted YouTube from strict rules relating to the use of cookies on federal agency Web sites.

The new White House Web site privacy policy promises that the site will not use long-term tracking cookies, complying with a decade-old rule prohibiting such user tracking by federal agencies. However, the privacy policy then reveals that Obama's legal team has exempted YouTube from this rule (YouTube videos are embedded at various places around the White House Web site).

While the White House might not be tracking visitors, the Google-owned video sharing site is free to use persistent cookies to track the browsing behavior of millions of visitors to Obama's home in cyberspace.

No other company has been singled out and rewarded with such a waiver.

In a blog post back in November, I criticized the Obama transition team's Change.gov Web site for its use of embedded YouTube videos. At the time, I stated that the practice might violate long-standing federal rules that forbid federal agencies from using persistent tracking cookies on their Web sites. It turns out that I was wrong: the transition team was technically not a federal agency and thus not bound by the anti-cookie rules.

Now that Obama is president, his official Web site is required to abide by the cookie regulations. Furthermore, as of Wednesday afternoon, several YouTube videos have been embedded on the White House blog. As soon as a visitor surfs to one of the blog pages that contain a YouTube video, a long-term tracking cookie is automatically set in the user's browser--even for those users who do not click the "play" button.

Someone on the Obama legal team seems to have read my previous blog post, as they've modified the White House privacy policy to specifically exclude YouTube's tracking cookies from federal rules that would otherwise prohibit their use:

"For videos that are visible on WhiteHouse.gov, a 'persistent cookie' is set by third party providers when you click to play the video.

This persistent cookie is used by YouTube to help maintain the integrity of video statistics. A waiver has been issued by the White House Counsel's office to allow for the use of this persistent cookie."

YouTube and cookies
Each time a new user visits YouTube, a unique permanent tracking cookie is issued by the Web site to the user's browser, which it stores. Whenever the user later revisits YouTube, that cookie is transmitted to the video-sharing site, allowing it to identify users and monitor their video viewing habits.

YouTube is also able to set and access a user's tracking cookie when she visits a third-party Web page that has embedded a video stored on the YouTube site (such as a blog or other Web site), even if the user never clicks the play button.

The moment that the flash file containing the video player is downloaded from YouTube's servers and displayed in the user's browser as part of another Web page, the cookie is transmitted to YouTube's servers. Considering how widespread the practice of embedding YouTube videos has become, this gives Google an amazing amount of data on the Web-browsing activities of hundreds of millions of Internet users--many of whom may not realize that such tracking data is being collected.

The White House policy is not being followed
The YouTube-related text in the new White House privacy policy implies that not all users will be tracked by YouTube. The policy notes that:

"If you would like to view a video without the use of persistent cookies, a link to download the video file is typically provided just below the video."

As of Thursday morning, this statement is false.

In multiple tests by this blogger with both Internet Explorer and Firefox, merely visiting pages on the White House blog causes YouTube to set a long-term tracking cookie in the browser--even if the user does not press the play button to start the video. After eight months, this cookie will be automatically deleted by the user's browser--unless, of course, the user visits another Web page somewhere else on the Internet containing a YouTube-embedded video, in which case, the eight-month cookie clock is reset. Given how widespread YouTube video embeds have become, this cookie essentially lasts forever.

While it is obvious that I am rather critical of this entire affair, I am willing to give the Obama Web team the benefit of the doubt in one area: the fact that their current Web infrastructure does not deliver on the promises made by their privacy policy.

The Obama White House Web site is only two days old, and so it is certainly possible that the team simply hasn't gotten around to deploying a more privacy-preserving system for YouTube video embeds. Protecting users who do not click "play" from automatically receiving a cookie is certainly possible; the Electronic Frontier Foundation in 2008 released a wrapper script for YouTube videos that provided this very feature. Let us hope that the Obama team deploys such a technology in due course.

Can YouTube be justified as a "compelling need"?
For the past 10 years, federal agencies have been prohibited from using tracking cookies on their Web sites, except in a few special cases. The Office of Management and Budget rule M-03-22 states that:

"Agencies are prohibited from using persistent cookies or any other means (e.g., web beacons) to track visitors' activity on the Internet except .... [when there is] a compelling need."

The question we must now focus on is this: Is the need for Obama to use embedded videos hosted by YouTube (and not, say, another company's video-streaming platform that does not force cookies upon its users) a use that can be reasonably described as compelling?

Presumably, this has been justified on the basis that YouTube forces cookies on the visitors of any Web site that embeds one of its videos. However, while Joe or Jane blogger has no bargaining power with YouTube/Google, the federal government certainly does.

In just the past couple weeks, YouTube has launched dedicated pages for both the House and Senate to show off their own videos, and the site also recently started allowing users to directly download copies of some videos. This latter feature has not yet been widely deployed across the site, and is seems to be limited to videos posted by Obama's team.

Given the famously close connections between Obama and Google, you'd think his tech team could negotiate for a cookie-less way to embed videos. At a technical level, this would be an easy enough change, even if it would deny Google the ability to collect even more information on millions of Americans.

Cookies and other federal agencies
Finally, the new White House YouTube rule may have a far broader impact on the way that federal agencies use Web 2.0 content. Simply put, if another federal agency embeds a YouTube video in its Web site without first having the agency's legal team issue a waiver, have federal rules been violated?

Up until this week, federal agencies have been free to embed Web 2.0 content in their own sites without any real need to consider the privacy risks posed to end users. The fact that the White House Counsel has felt it necessary to issue such a waiver for YouTube videos appearing on the White House Web page could be reasonably interpreted to mean that such a waiver is now required for all embedded Web 2.0 content that might force cookies upon end users. This is certainly new legal ground.

Consider, for example, the Transportation Security Administration, which has posted YouTube videos to its blog numerous times over the past year. Its privacy policy makes no mention of YouTube cookies. Could this lead to issues for the TSA Web team, or perhaps even congressional investigations? Given my own history with TSA, I certainly hope so.

Why Obama should ditch YouTube

by Chris Soghoian

Update at 9:30 a.m. PST: Video audience figures have been updated.

President-elect Barack Obama has now posted his second weekly address to YouTube, and it has already gotten more than 411,000 views. A week ago, I criticized the use of YouTube by Obama's transition team, calling it a no-bid giveaway to the Google-owned video-sharing site.

The solution I called for then--the adoption of BitTorrent as the official distribution platform for Change.gov--was, admittedly, a pipe dream.

In this post, I'll explain why the government needs to step up and host its own videos and why it is simply improper to rely on YouTube to foot the bandwidth bill for Obama's messages to the people. I will also make the case that the use of YouTube and Google Analytics by the Obama transition team violates the privacy of Web site visitors and possibly even violates federal rules banning the use of permanent tracking cookies on government sites.

YouTube as the platform of choice
The announcement a couple weeks ago of Obama's decision to use YouTube for his weekly addresses led to headlines across the world. The president-elect's use of streaming video technology was hailed as revolutionary or, as one transition team rep gushed, "just one of many ways that he will communicate directly with the American people and make the White House and the political process more transparent."

Obama's team uploaded his first video address to YouTube (928,000+ views), AOL (220+ views), Yahoo (8,400+ views), and MSN (545+ views)--all figures as of Monday morning.

In keeping with the spirit of this posting, the above video is not embedded.

(Credit: YouTube)

For his second weekly video, the Obama team seems to have ditched AOL and only uploaded the video to YouTube, Microsoft's MSN, and Yahoo. Web 2.0 start-ups such as Veoh, Vuze, Revver, and Blip.tv have not gotten any love.

While the transition team should be commended for uploading the video to multiple sites (albeit all owned by multibillion-dollar tech titans), the difference in the number of views is rather startling. Without access to accurate stats (which are not public), it is tough to know how many YouTube views came from people viewing the video embedded into the Change.gov site, searching YouTube, or watching a copy embedded into a personal blog or other news site.

However, I do think it is fairly reasonable to assume that a decent percentage of those nearly 1 million views came from people visiting Change.gov, the taxpayer-funded, official site of the Obama transition team. It is those hundreds of thousands of viewers who clicked the play button to load and stream a video embedded from YouTube's servers that are the focus of this post.

Privacy risks
YouTube, like many other sites, uses persistent cookies to track repeat visitors. Thus, when a regular YouTube user views a video embedded in a blog or other third-party site, the user's cookie is automatically sent to YouTube's servers--even without the user clicking the play button. Given the widespread use of embedded videos, this gives Google, which owns YouTube, an even better idea of the surfing habits of millions of people around the world.

And even if you believe Google's "do no evil" motto, it seems at least a little bit creepy for the company to track each time someone visits Change.gov--especially when that person doesn't actually press the play button to watch Obama's latest message to the people.

The privacy risks associated with the widespread use of embedded videos is something that has caused significant concern for privacy activists--enough for the folks at the Electronic Frontier Foundation to develop the privacy-preserving MyTube tool for Webmasters. If the Obama team insists on sticking with YouTube embeds, perhaps it will at least consider deploying MyTube to protect the privacy of citizens who visit the official transition site.

The privacy risks aren't just limited to YouTube.

Just a week ago, Dan Goodin at The Register criticized the use of the Google Analytics Web-tracking code in the Change.gov site--which also sets a permanent tracking cookie. Although he mostly focused on security risks, and not privacy-related threats, he blasted Obama's Web design team, stating that:

The failure of Obama's Webmasters to follow anything remotely like best practices is more than a little troubling because it suggests they don't fully grasp the security realities of living in a Web 2.0 world.

Eight years ago, the issue of cookies tracking users on government sites was a fairly big issue in tech policy circles, drawing the attention of those in Congress. Eventually, the Office of Management and Budget issued a directive that forbid the use of persistent cookies on federal agency sites.

The Obama team's use of both YouTube and Google Analytics raises serious privacy concerns and likely clashes with the OMB directive.

If Obama's transition team can afford to lease a jet for the president-elect and to pay for staff salaries, BlackBerrys, and hotel rooms, why can't it also pay for a few Web servers capable of serving up Flash video?

(Credit: Change.gov)

To be clear, Change.gov is not creating or requesting its own persistent cookies. However, due to the embedding of YouTube videos and Google Analytics Web-tracking code in the site, visitors will be transmitting cookies to Google's servers. Since the YouTube cookies are not set directly by the Change.gov servers, it is unclear whether the Google cookies violate the specific OMB directive. Even if they do not, they clearly violate the intention of the rule--which was created in the days before embedded videos or third-party-hosted Javascript.

The official privacy policy listed at Change.gov makes no mention of cookies, nor of the collection of visitor information by Google's servers. The privacy policy does, however, pledge "not to make personal information available to anyone other than our employees, staff, and agents." At best, the Obama team copied a boilerplate privacy policy from somewhere else and overlooked the use of YouTube and Google Analytics. At worst, it seems pretty deceptive.

When reached for his thoughts, Marc Rotenberg, executive director of the Electronic Privacy Information Center told me:

On the upside, the transition people have done a good job with the ethics in government rules for transition team members. Now they need to revise the Change.Gov Web site and respect the rights of citizens who are seeking information about the new administration.

Lots of traffic
The low-quality video YouTube video embedded into the Change.gov blog is 7MB. When multiplied by more than 900,000 views, we find out that Obama's first video led to the consumption of over 6 terabytes of bandwidth. If the Obama team had to pay for the data, instead of getting it for free from YouTube, it would have cost nearly $1,000, at least if it used Amazon.com's S3 cloud-hosting service.

While YouTube did not serve any advertisements within or around Obama's chat, each of those 900,000+ viewers did see YouTube's name prominently placed within the Change.gov site (as a watermark in the bottom corner of the video). Once the three-minute video is over, viewers are given the ability to watch other related videos (which might have advertisements) or, with one click, to navigate directly to the Google-owned video-sharing site, which certainly has advertisements.

Furthermore, I'm sure that Google's PR team was absolutely overjoyed with the thousands of newspaper articles that flatteringly tied the president-elect to the video-sharing platform. While all press is good press, it is likely such Obama-related press is even better.

Defaults matter
The Obama team's uploading of its weekly videos to YouTube is fine--providing, as it currently does, that it also uploads the videos to a few other places too. As the videos are not copyrighted, members of the public are free to redistribute them via other platforms (as the LegalTorrents P2P site has done), and even mash them up. This is great, and I support this embrace of Internet distribution by the president-elect's team of geeks.

I do, however, have a problem with the use of YouTube-hosted embedded videos on the official Change.gov site.

The transition team has a budget of over $12 million. If it can afford to lease a jet for Obama and to pay for staff salaries, BlackBerrys, and hotel rooms, why can't it also pay for a few Web servers capable of serving up Flash video? Isn't it a bit tacky for the federal government to be relying on Google to host its videos?

It's as if the entire Obama transition team has adopted Hotmail's free e-mail service for its daily communications--with each e-mail sent by an Obama adviser followed by a signature pitching one of Microsoft's products: "See how Windows Mobile brings your life together--at home, work, or on the go."

Obama raised half a billion dollars through online donations during his campaign. His was the first presidential campaign to employ a chief technology officer (a computer geek formerly at the travel site Orbitz). These guys know what they're doing when it comes to technology; they design beautiful, interactive sites and have relied upon complex data-mining algorithms to profile and target individual voters and donors. If they wanted to, they'd have no problem installing a few dozen Adobe Systems Flash streaming servers. However, since YouTube will gladly foot the bill, the Obama team hasn't felt the need.

During his campaign for the presidency, Obama didn't call for a Web 2.0 government, but for a Google government--something that CEO Eric Schmidt, who is now serving as one of Obama's economic advisers, was probably very happy to hear. While I love conspiracy theories as much as the next guy, I don't really see one here. However, given the close connection between Obama and several higher-ups at Google, it is better to avoid the appearance of a conflict of interest.

Thus, it is time to bring an end to embedded YouTube videos on Change.gov. By all means, use streaming video to reach the masses, but let the bits flow from government-owned servers (preferably without privacy-invading cookies). If bloggers wish to embed YouTube videos of the speech on their own sites, that is fine. But Obama shouldn't.

Obama's mixed signals on transparency

by Chris Soghoian
  • 12 comments

How far does President-elect Barack Obama take his commitment to transparency? Is it a serious pledge to shake up Washington, to apply sunlight to the often shadowy depths of the executive branch, or is it merely a very good marketing campaign?

In the past few days, the public has received some seriously mixed signals on the issue--his decision to use YouTube to speak to the American people, and then press reports indicating that he may give up e-mail as president to avoid oversight.

On Saturday morning, Obama's first video address to the people was posted to YouTube. A copy of the video was embedded into the Change.gov blog, and has since received over 650,000 views. In describing the new YouTube effort, an Obama spokesperson told The Washington Post that:

"This is just one of many ways that he will communicate directly with the American people and make the White House and the political process more transparent."

Contrast that bit of hype to the news that the president-elect will likely be giving up his prized Blackberry, and like previous presidents, giving up e-mail the moment he takes office, due to the fact that e-mails can be subpoenaed by Congress, or later end up in the presidential library. As The New York Times reported:

In addition to concerns about e-mail security, [Obama] faces the Presidential Records Act, which puts his correspondence in the official record and ultimately up for public review, and the threat of subpoenas. A decision has not been made on whether he could become the first e-mailing president, but aides said that seemed doubtful.

The real issue here is not one of keeping the president's in-box safe from Chinese hackers, but keeping it safe from Congressional investigators.

If the National Security Agency, Central Intelligence Agency, and a number of other spy agencies can provide e-mail access to their tens of thousands of employees, then the president's e-mail can be kept safe and secure. The U.S. government has classified networks, over which classified data flows, and for obvious reasons, these are not connected to the general purpose Internet. And for the spy on the go who needs real-time access to top secret information? The NSA has its own smartphones made for handling classified data.

It is important to note that no one from the Obama administration has gone on record to speak about this issue yet, and so while it is certainly worth discussing, it is still too early to pass judgment upon President-elect Obama's e-mail policy.

In the meantime, the press has reached out to members of past administrations to share their thoughts on the clash between Obama's stated commitment to transparency and a natural desire for privacy. On this issue, former Bush Press Secretary Scott McClellan told the Associated Press:

"While he has pledged an open and transparent government, I doubt the president-elect is interested in subjecting his own personal communications to that standard." He added, "He will have to think very hard about whether he wants to make his own words that subject to open records by having his own e-mail and his own BlackBerry."

If the next president opts to use e-mail, it will almost certainly become part of the public record at some point. However, that lack of e-mail privacy is far more a feature than a bug.

Without being able to follow the paper trails, and see what is being said by whom in the White House, how can real oversight be achieved? The willingness of the next president to use e-mail (and even a smartphone), even with the knowledge that his messages might later be subpoenaed by Congress, will be the best way for him to demonstrate his belief in the importance of sunlight.

As for the issue of Obama's right to privacy--remember that we are not talking about the president's personal Hotmail account, but his ability to use e-mail for work purposes. Americans generally have little to no legal rights to privacy relating to their use of Internet at work--at least with regard to their employer. Bosses have the right to install Web filters, monitoring software, and to read through specific e-mails.

With that in mind, consider that Obama is a public servant who works for us. We, the public, are his collective boss, and so why should he have any privacy rights over the e-mails he sends on our time? If the White House is the People's House, then its e-mail servers are the People's Servers, and we have a right to see every bit of text that gets sent through them at our expense.

Finally, if the president is serious about transparent government, perhaps he'll pledge to not allow his staff to hide behind executive privilege once Congressional investigators come calling (as I am sure they eventually will). Sure, this will be more unpleasant and potentially embarrassing than merely throwing a few carefully scripted videos up on YouTube. However, such a commitment would actually be transparency we can believe in.

Dear Obama: Use BitTorrent for your Fireside podcasts

by Chris Soghoian

Calling for the separation of Google and State.

The news that President-elect Barack Obama will be using YouTube to distribute his weekly "radio" address has been met by general fanfare among the digerati.

This might seem like a bold move--and compared with the relatively boring podcast MP3s of Bush's weekly speech hosted at Whitehouse.gov, it is. However, putting President-elect Obama's video podcasts on YouTube is hardly Change We Can Believe In.

By exclusively hosting his videos at YouTube, the Google-owned dominant player in the user-generated video industry, the Obama campaign has effectively issued its first no-bid giveaway of the next administration.

If Obama really wants to demonstrate his Web 2.0 bona fide intent and prove that he's actually interested in shaking things up, he'll use BitTorrent, the disruptive file-sharing tool that arguably dwarfs YouTube in popularity.

Let's explore a few reasons why Obama should ditch his YouTube plans and switch to BitTorrent:

  • As demonstrated by the recent flood of constituent complaints to the House and Senate during the banking bailout, the .gov network simply can't deal with lots of traffic.
  • It's not the government's role to pick industry winners and losers. Sure, YouTube has millions of users, but I'm sure that the other Silicon Valley-based user-submitted video sites would love to draw the eyeballs of Obama's podcast subscribers. What about Veoh, Vuze, Hulu, Revver, and Blip.tv?

  • While it's awfully nice of Google-YouTube to volunteer the hundreds of gigabytes of bandwidth necessary to host Obama's video content, is it really appropriate to further expand the link between Google and the Obama Whitehouse?

    Google CEO Eric Schmidt already has Obama's ear as a member of his economic advisory board; the Obama campaign has likely paid hundreds of thousands of dollars to Google for AdWords advertising during the campaign; and Google.org's Sonal Shah has landed a key key role on Obama's transition committee. Simply put, things are already close enough between Change.gov and the Google Gang.
  • There are no copyright issues--since the videos will be made by the federal government, they are automatically in the public domain. Thus, it is perfectly OK for them to be shared via peer-to-peer technologies.
  • It'd give Obama a reason to care about Net neutrality. Some on the left are already voicing fears that Obama will soften on his commitment to the Net neutrality cause. Once his weekly addresses are hosted via BitTorrent, he'll have a vested interest in keeping the pipes tamper free. In such a scenario, any antifile-sharing shenanigans by Comcast or other ISPs would directly impact Obama's ability to speak to the people.

  • The Canadians already do it: CBC--Canada's version of PBS--has had highly successful trials of BitTorrent as a low cost, high-throughput method of distributing video content. Since we're hopefully going to copy the Canadian's obviously better health care system, why not similarly learn from their use of file sharing?

The time is right for the U.S. government to adopt BitTorrent. Mr. Obama, be bold, be brave, and upload to The Pirate Bay.

McCain seeks special 'fair use' copyright rules for VIPs

by Chris Soghoian
  • 34 comments

John McCain's presidential campaign has discovered the remix-unfriendly aspects of American copyright law, after several of the candidate's campaign videos were pulled from YouTube.

McCain has now discovered the rights holder friendly nature of the Digital Millennium Copyright Act, which forces remixers to fight an uphill battle to prove that their work is a "fair use."

However, instead of calling for an overhaul of the much hated law, McCain is calling for VIP treatment for the remixes made by political campaigns.

McCain's proposal: complaints about videos uploaded by a political campaign would be manually reviewed by a human YouTube employee before any possible removal of the remix. The process for complaints against videos uploaded by millions of other Americans would stay the same: instant removal by a computer program, and then possible reinstatement a week or two later after the video sharing site has received and manually processed a formal counter-notice.

With 11 homes and 13 cars, it's not terribly surprising that McCain is calling for special treatment for the YouTube videos of politicians. As for the "fair use" claims of the poor starving masses: Let them eat cake.

On Tuesday, the McCain campaign sent a formal letter to YouTube asking for this two-tier system for "fair use" complaints. Copyright-guru Larry Lessig called it a "fantastic letter", adding "bravo to the campaign" in a post to his blog. Since then, the technology press has been pretty supportive, although the focus of the coverage seems to mainly be along the lines of "McCain realizes that fair use claims are uphill battle." This is the wrong message to send, and as much as I respect Professor Lessig, I have to call him out here. He is wrong. McCain should be criticized for his attempt to get special treatment, and Google/YouTube need to treat all users the same way.

All claims of fair use are equal--yet some claims are more equal than others.

The only way we will get an effective overhaul of copyright laws will be by forcing politicians to suffer along with the masses. The minute a special set of rules are made for those in Congress, the incentive to fix the system will disappear. To drive this point home, consider the following:

During the confirmation hearings for Judge Robert Bork, the Washington City Paper obtained a copy of the Republican nominee's video rental records. Alarmed at the possibility that their own rental histories would be revealed by the press, members of Congress jumped to pass comprehensive privacy legislation for the video rental records of all Americans. Up until the Bork fiasco, there had been no real incentive to fix anything, but once the risk to their own records was made clear, Congress acted. As a result, we are now all protected by the 1988 Video Privacy Protection Act.

Compare this to the horrible situation at airports. Americans are routinely harassed, prodded, poked and humiliated by employees of the Transportation Security Administration. While we stand in line like sheep, congressmen get to skip through the security lines, avoiding the entire process. Given the fact that they don't have to suffer at the hands of TSA, it's not terribly surprising that they have little incentive to fix the problems faced by the rest of us.

These two examples should make it clear--we cannot allow politicians to receive special treatment in copyright and fair use disputes. If anything, campaign videos should receive substandard treatment. McCain's videos deserve to rot in purgatory at the back of the DMCA queue, behind videos of toddlers, skateboarding dogs, Starwars Kid remixes, and the hundreds of clips of the dramatic chipmunk. Perhaps then, the senator will throw his weight behind comprehensive copyright reform that'll result in real benefits for the rest of the remix-population.

Legal liability for YouTube viewers

by Chris Soghoian

Updated on 5/19/08 with comment from RealPlayer (see below)

Users of YouTube and other video-sharing sites could face $750 per clip penalties if they have watched a video that was uploaded without the copyright holder's permission.

Copyright infringement in the United States strict liability offense. What this means, is that users are liable when they illegally copy works, even if they're not aware that this is wrong, or that the work is protected by copyright.

As an example, let us consider the popular video sharing website YouTube.

Every week, 6 days after the show airs, HBO uploads the most recent episode of "Real Time with Bill Maher." However, within a few hours of the show's TV broadcast, a number of other users upload copies that they have recorded with their computers.

When a user visits YouTube, and searches for "Bill Maher", he will see a large number of results - some of which will be for official content uploaded by HBO, and the vast majority of which is for copyrighted content illegally uploaded by other users.

According to a strict reading of the copyright laws, and discussions with legal scholars, users could unknowingly be liable if they click on the wrong YouTube link. The fact that they're not aware that a video was illegally uploaded is irrelevant. All that matters is that they clicked on a link, and watched the video.

For BitTorrent websites like The Pirate Bay, where the vast majority of the files are illegal, it is at least semi-reasonable to expect most users to know that they are engaged in an illegal act. However, for sites like YouTube, where both legal and illegal content are available on the same platform, it is significantly trickier. How exactly, are the less-tech savvy amongst us supposed to determine if a file is legal to watch?

Copytraps

The issue of unintentional home user liability is the subject of a recent paper by Ned Snow, a law professor at the University of Arkansas. In "Copytraps", Professor Snow argues that copyright law unfairly exposes end users to significant liability, for actions which they have no reason to believe are illegal.

Professor Snow puts forth the following example: A user visits Google, and searches for the name of a band they like. One of the first results takes them to a website, named "legal-music-downloads.com". Once there, the user hands over her credit card, and pays $.99 per song to this unknown website. Now, imagine that "legal-music-downloads.com" is in fact a fraudulent website run by a couple guys in Eastern Europe. They download files from BitTorrent, and then illegally re-sell them to American consumers.

As Prof. Snow describes, the fact that the end user thought she was participating in a legal purchase is irrelevant. All that matters is that she has copied (downloaded) a copyrighted work, which was not sold through legitimate means. This user could be liable for up to $750 per song.

This may sound crazy, but it's completely possible under the existing system. Yes, the RIAA and MPAA have for now, gone after people who were sharing files. However, there is nothing in the law forcing them to stick to just those users. They are legally permitted to go after downloaders too.

Experts respond

To make sense of this, I turned to a few other experts in copyright law. First, I spoke with Corynne McSherry, a staff attorney at the Electronic Frontier Foundation. McSherry told me that the scenarios I outlined were not beyond imagination, and quite possible under existing copyright law.

As an example of copyright holders going after downloaders, she pointed to a 2006 attempt by the Embroidery Software Protection Coalition to get the identities of all the participants of an online embroidery discussion forum. In support of their claims, the Coalition compared the stitchers' online screeds to "terrorist activities" and accused them of posting slanderous statements "that marched across the Internet bulletin boards and chat groups similar to Hitler's march across Europe."

The Embroidery Coalition, following tactics similar to the RIAA and MPAA, threatened grandmothers with lawsuits for downloading copyrighted embroidery patterns from the Internet. These little old ladies were given the choice of either paying a few hundred dollars, or facing a lawsuit.

Luckily, the lawyers at the EFF were able to get the Coalition to back down, but this does at least prove that left unchecked, copyright law can be used to go after the end users.

The EFF's McSherry told me that the penalties in copyright law were "not like many other areas of the law where you have to show harm." Thus, illegally copying a song that is sold for $.99 at the iTunes store can still lead to a $750 per song fine. McSherry labeled this as "completely disproportionate" and said that because of this, "for regular people, who don't have thousands of dollars, the inclination is to settle (the cases), rather than to fight."

YouTube users at risk

While Professor Snow focuses on the example of lying websites, I am personally far more interested in liability for users of major sites like YouTube.

Sherwin Siy, an attorney with Public Knowledge, told me that my YouTube fears might be overblown. Siy points to a difference between downloading a video, and streaming it. He told me that "arguing that a buffer copy (for a streaming view) is a duplication, that's even more of an uphill (battle), and the potential awards might not be worth the attorneys fees." He added that "merely watching a video on your screen, authorized or not, isn't going to be an infringement if you're not publicly performing or copying it."

Siy also noted that copyright law does allow for a reduced $200 per work penalty for infringement, if the pirate can prove that they had no reason to believe that they were infringing.

Updated:

Siy clarified his point in a followup email: "For instance, if my local network TV affiliate were to broadcast an infringing copy of a TV show, and I were to watch it at home, I would definitely not be liable. The copytraps idea might come into play had I (however innocently) taped or DVR'd the broadcast."

While Siy makes some good points, I will have to disagree with him on the issue of viewing vs. downloading. There are many off the shelf tools that allow users to download YouTube videos. The most widely deployed of these is RealPlayer, which automatically makes allows the user to make a local copy of every YouTube video that a user watches. YouTube has no way of knowing if someone is streaming or downloading a video - as it's simply a case of transferring bits over a wire. If the RIAA or MPAA ever subpoenaed YouTube's logs, they wouldn't be able to differentiate these users either.

YouTube's Position

A few years ago, a number of major firms started threatening Linux end-users with patent lawsuits. In response, one or two Linux companies to shield their customers from such lawsuits. That is, buy Linux from us, and we'll cover any potential legal bills.

Thinking along these lines, I reached out to YouTube to get their perspective. I wanted to know if they would offer to foot the bills of users who were sued after watching a video on their site. I also wanted to find out if YouTube has ever disclosed a list of infringing viewer IP addresses to a copyright holder.

YouTube's spokesperson ignored my actual questions, and instead told me that:

We prohibit users from uploading infringing material, and we cooperate with all copyright holders to identify and promptly remove infringing content as soon as we are officially notified.

As a company that respects the rights of copyright holders, we expect to continue to take the lead in providing state of the art DMCA tools and processes for all copyright holders.

While the liability for end users remains unclear, there is certainly the potential for some nasty lawsuits, should the copyright owners decide to go down that path. In a conversation with me, Prof. Snow described a scary future with Copyright Trolls who delay sending takedown letters to websites, so that the number of infringing users (who the company can later go after) will increase.

A scary future indeed.

Update: Jeff Chasen, a VP at RealPlayer contacted to let me know that I had erred in my original blog post. He told me that:

RealPlayer does not automatically download or make local copies of videos from YouTube. RealPlayer 11 gives users the option of downloading the video they are watching, but it requires that the user click a button to initiate the download. No copies or downloads occur until a user explicitly takes an action.

I do stand by my original point though, which is that YouTube (and any copyright holder who gets a list of the views/downloads via a subpoena) has no way to tell when a user is watching a video, and when a user is downloading them via a single-click RealPlayer tool.
