BodyPrint technology can unlock your phone using your ears
Apple recently introduced Touch ID, which is a huge upgrade from the traditional passcode. BodyPrint, a new technology being developed in the Yahoo Labs, could take things a step further and would allow the user to unlock their phone with their ear if they wanted to.
So, how does it work? The experimental system uses the touch screen as a scanner and because it is scanning larger areas, it does not require the expensive high-resolution technology that is required for fingerprints and could thus be utilized on all touch devices.
