Mobile Challenge

by jhondaw / November 21, 2011 6:08 AM PST

Hi, we are a data security company and we have an interesting challenge in the mobile world: We would like to send a security code that will appear simultaneously on the incoming call screen of the receiver's phone before he answers the call.On top of that, we would like to send an additional security code during the conversation, and we would like it to appear on the receiver's phone screen (next/under the call ID and call duration) in real time. Any ideas?
Many thanks!<div>John

Sorry but let me tip my hand a little more. Not only have I been on 2 way pager designs (way old stuff) but today am involved in current cellular development and handheld apps.

It appears you are trying to get around what you do to make this work. In short, you will not be doing this without working with the carriers.

Thanks Bob. I was just hoping there's a way around it, like sending the data at the same time as the call, but via a reliable yet different service. It is appear as thought you believe the only way is really to strike a deal w AT&T, Verizon, Sprint etc... If that's the case, it is so disappointing!

The only way is like Skype.

And you send a message or datagram to an app then make the call. But this presupposes they install your apps.

So there it is. They would need to install your app first and you need another pipe (internet connection) to send the first message before the call.

I know this area and it's issues. As I shared, I'm working on a system now that we send messages around in what they call "M2M".

Got it

Yes, this is an option, although developing your own dialer is costly and may come with questionable call quality.
I guess using a 2-way sms / push notification is one way to do it, too.
Easier said than done, I take it - and I really appreciate all your answers and advice.
I wish there was a way to use the telcos call, without the need to strike a deal w them, so that I wouldn't need my own VOIP. All I need is to guarantee that the data/image will go alongside the call and will not be delayed.

In our world the data goes first. Get's an ack then

In our M2M app, the data goes first. We use UDP so we send the UDP out, then wait for a reply from the remote system (an acknowledgement) and then are ready for the next step.

I've seen folk try to do this "alongside" or in parallel and they fail every time.

Hi Bob, do you think all these folk fail because the couldn't strike a deal with the cell carriers, and if so - how wold you go about it when approaching those companies?

You head to the site and find phone numbers and start calling. Or go to the trade shows.

Here's one coming up ->

There are others but this was the last one I went to.

It should be an uphill battle, to say the least!
