Hello, I'm Luke Westaway of CNET here at Mobile World Congress in Barcelona taking a look at an eye scanning security system.
So this system is called Eyeprints by a company called EyeVerify and how it works is your phone will use its front-facing camera to take a scan of the veins in the corner of your eye.
It needs a 2 megapixel front-facing camera, that's the minimum resolution to get a good enough picture of your eye.
Once it's got that picture, it then saves it, so that if an imposter tries to pinch your phone and take a look at your precious documents, they won't be able to get access to them because their eyes don't match.
If your phone doesn't have a good enough front-facing camera, then help is at hand because the app can also use a rear-facing camera and gives you audio instructions telling you to look up into the left, or up into the right.
The technology is quite clever.
It seems a little bit more hard to fool than something like Google's face unlock which you can faux just by using a picture of someone's face.
This is still in development though; EyeVerify is going to be trying it to companies like app developers or phone manufacturers to implement in their software or hardware so hopefully we'll see it cropping up somewhere soon.
