New Apple Patent to bring Face unlock to iOS

A recently discovered patent submitted by Apple details a method of unlocking an iDevice via face-recognition a'la Galaxy Nexus...kind of risky based on the privacy concerns surrounding using a photo to unlock the phone.

As described in the above image discovered by PatentlyApple.com, the device would sense a user approaching and wake from sleep to activate its image processor.  At this point, facial recognition software can be executed to match the user's face and unlock the device.  Business users can set even higher levels of security.
