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. [1]

Very useful indeed.

The next time you are in need to make an urgent phone call – let’s say to the police – you will have to have the proper lighting and the proper posture and make the proper gestures in order to unlock your phone. And until you do that, you will be either dead or under serious problems…

But your phone will be secure. Don’t worry about that.
