Apple Insider reports that Apple has been awarded a patent for facial recognition technology that controls a device such as an iPhone, iPad or Mac.

For example, during an incoming phone call, an iPhone may be able to “sense” that someone is looking at the device’s screen. If the person is not an authorized user, the iPhone’s screen remains off and only a ringtone or vibration alert is provided. If the person is an authorized user, the usual incoming call UI is displayed.

In another example, an incoming email can be blocked from view unless the authorized user’s face is detected by the system. This implementation would be helpful for users who choose to display part of the message in the lock screen.

Is this linked to Apple’s purchase of PrimeSense?
