Researchers recently found that a new feature in Android 4.0, which enables users to unlock their devices using facial recognition, isn't particularly secure.

"A video demonstration created by mobile blog SoyaCincau shows that the Face Unlock feature can be fooled by showing it a mere image of the face used to set up the locking mechanism," writes CNET News' Elinor Mills.

"The video shows someone unlocking a Galaxy Nexus running Android 4.0, also known as Ice Cream Sandwich, by holding in front of the device a digital photo taken of him that is displayed on another phone," Mills writes.
