Google Patents Frowns and Winks To Unlock Your Phone

Excelcia writes: Users could soon be asked to pull a series of faces to unlock their Android phones or tablets. Google has filed a patent suggesting users stick out their tongue or wrinkle their nose in place of a password.

Requiring specific gestures could prevent the existing Face Unlock facility being fooled by photos. The software could monitor if there were changes in the angle of the person's face to ensure the device was not being shown a still image with a fake gesture animated on top.
