Android 4.1 Checking If You Are Alive before the Phone Unlocked

Face-unlock has been improved in the new version of Android. It is no longer possible to cheat face-unlock with a photo.

The new feature Face-unlock, which was introduced in Android 4.0-Ice Cream Sandwich has become more secure in Android 4.1 – Jelly Bean.

Face-unlock makes the phone able to recognize your face and only locks the phone up you. But since the Face-unlock was introduced, it was Android enthusiasts quick to test the level of security in the solution.

It turned out as quickly, that just by keeping a photo op in front of the phone, was the face recognized and the phone unlocked, writes our site.

It is changed in Android 4.1 Jelly Bean, where there will be done a so-called Liveness check. It goes short and good on the check of sign of life from the person, so that there cannot be a still photo.

Liveness check looks for whether the person blinks his eyes, and if so will be your phone closed up.
