But Face Unlock has a flaw. It unlocks the phone when you show it your picture too. This is where EyeVerify comes into the picture.
The company's Eyeprint technology scans users' eye veins and lets them unlock the phone or open applications. The prototype app was demonstrated at MWC 2013.
It takes a picture of your eye, which then goes through a segmented verification process that is difficult to hoodwink.
