The Redmond, Wash.-based software giant plans to release a technical preview of the software, code-named InfoCard, by the end of May, Microsoft said. It will also include other technologies designed to make using digital identities easier and safer, Microsoft's senior executive in charge of security, Mike Nash, said Tuesday.
The release is for software developers, who will be asked to give Microsoft feedback on the technology, Nash said during his monthly security Webcast. In addition to InfoCard, Microsoft is also planning preview releases of technologies that it is pitching to enable the various identity systems used on the Internet to work together, he said.
Microsoft is getting ready to give developers a peek at its InfoCard identity management software for Windows.
It's a step forward for InfoCard, Microsoft's second attempt at an authentication technology after its largely failed Passport.
"One of the big challenges that people face today is that there are many different kinds of identity systems," said John Shewchuk, an architect in Microsoft's distributed systems group, who was also on the Webcast.
In a similar vein, Microsoft and Sun Microsystems last week demonstratedunder development that's designed to let someone log in once to use network services that previously required separate authentications.
InfoCard will be the most visible of Microsoft's efforts to PC users. It is designed to provide secure storage for identity information that will be shared with online services such as Web stores.
The plans are reminiscent of Microsoft's largely failed efforts with Passport, a single sign-on service it unveiled in 1999. InfoCard is a new attempt, one that could address the complaint many critics had with Passport, which was that people's information was managed by Microsoft instead of by the users themselves and the businesses they dealt with.
The developer preview is important as Microsoft moves from just talk to actually sharing some of the work in progress.
How will it work?
InfoCard on your PC will hold personal data such as login names, passwords and information for making payments. This example deals with buying a CD online with a Web store and bank that support the technology.
InfoCard takes care of logging you in to the online music store.
After you place an order, the store connects with InfoCard on your PC using Web services.
You're then prompted with a request to choose how you want to pay. This is based on the information InfoCard holds for you, which could include credit card or bank account numbers. Personal data, such as the credit card information, can be stored on your PC or at sites that you authorize.
Once you've selected how you will pay, your PC will connect with the bank or credit card issuer and request payment to the music store.
The store will get confirmation that it will be paid either directly from the bank or credit card company or through you. The store will never have seen your financial information.
InfoCard holds payment authorization and details in the same way that a wallet holds credit cards, according to the software maker. "It makes it supereasy for the end user to pick among their different kinds of credentials," Shewchuk said.
With InfoCard, the online buying experience would change. When a user buys a book online, for example, the Web store would ping the user's InfoCard application on the user's PC for payment. The user then authorizes payment, which is routed to the applicable financial institution. The bookstore does not need to know the user's credit card number or financial data.
For InfoCard to work well, commerce Web sites will need to adopt the technology, as will other businesses, such as credit card companies and banks, Microsoft said.
But InfoCard's use will not be limited to storing and supplying ID information for making online payments or logging in to Web sites, Microsoft said. In addition, the first version will also support other authentication technologies, such as the x509 certificates used for smart cards, according to Shewchuk.
Insiders expect InfoCard to be part of Longhorn, the next major release of Windows due next year, but Michael Stephenson, a director in
