Gizmodo : Picture passwords for cameraphones Instead of using a password to unlock your cellphone, a Japanese company called Earth Beat has come up with a way to use a picture instead. You just snap a picture of yourself with your cameraphone, then whenever you want to unlock the phone it uses face recognition technology to verify that the person trying to use the phone matches the photo it has in storage. Which also means you might be unable to use your phone if you ever change your appearance.
Yet another use! My article idea is getting unwieldy.
