Android Phone “Face Unlock” Feature Fooled by Picture
Looks like the Face Unlock feature on the new Galaxy Nexus is more of a novelty item than a security feature. In the video above you can see the phone being unlocked by a picture from another cell phone.
According to PacketStorm Security this could be a security risk, “With your face literally all over the internet (think Facebook, Twitter, LinkedIn, etc.), this could be a potentially serious flaw in Android 4.0, codenamed Ice Cream Sandwich and unveiled last month in Hong Kong.”
