Forget TouchID. The next smartphone security code could come from your ear. Amazon has patented an ear recognition technology that can identify a user based just on ear shape, as seen through a phone’s front-facing camera.
The device, according to the patent, could “determine whether the user is holding the device near the user’s right ear or left ear, and adjusts functionality of the device based at least in part upon how the user is likely holding the phone” when making a phone call or listening to an audio file. That means the technology could adjust the volume based on your position.
