The posts about how to break the screen lock are very frequently visited. This is why I thought it’s time to give you a short update and provide you with a Python script, that can do most of the attack in an automated way.
Since Android 4.0 is available, the user has the possibility to unlock his smartphone by looking in the front-camera. This feature is called face unlock.
Just some hours after Google has presented the new Android version including this feature, it was broken by some blogger who just hold a picture of the person the smartphone belongs to in front of the locked smartphone. As a proof, there are plenty videos on youtube. With this demonstration in mind, you have to come to the conclusion that face recognition isn’t a real lock feature, its more a fancy way of the old screen lock were you just have to swipe over the display.
