Android Jelly Bean will add 'Liveness Check' to Face Unlock feature

Google has improved the security of its Android Face Unlock feature with a new feature within the Jelly Bean 4.1 release.

The admittedly 'low security' Face Unlock tech was introduced within Android Ice Cream Sandwich, but was soon found to be easily by-passed using a photograph of the phone's owner.
Jelly Bean, announced at Google I/O, offers a solution which requires the user to blink before it will allow them into the phone.
