Apple Inc. has been grantedan officialpatent ona technology that usesfacial recognition to unlockmobile phones.

Published byThe U.S. Patent and Trade Office Tuesday, the patent documentshows that Apple has been developing thisiPhone feature since at least 2011.

"In an embodiment of the invention, an unlocked mobile device is configured to capture images, analyze the images to detect a user's face, and automatically lock the device in response to determining that a user's face does not appear in the images," reads the patent application.

The file goes on to describe the way this technology works.

Photos match, phone unlocks

Essentially, a user would bring the phone up to his or her face, at which point a sensor would trigger a processor to capture an image. That image would then be analyzedagainst animage of the user's face that waspresumablytakenwhen he or she set the feature up. If the faces in both photos match, the phone would automatically unlock.

Apple also notes that this technology could be used to identify additional authorized users, much like the biometric fingerprint scanner it unveiled in 2013 withthe iPhone5S.

As Recode'sDawn Chmielewski points out, Apple is not the firstmobile phone producer to show interest infacial recognition technology.

Most contemporaryAndroid phones already have a feature thatautomaticallyunlocksaphoneupon recognizing anowner's face, though"Google warns this is less secure than, say, a password, since someone who looks like you also could unlock the phone," Chmielewski writes.

Apple's technology would also improve upon the existing Android feature in that users wouldn't have to activate their screens by pressing any buttonsinstead, Apple tracks the phone's movements to see if a user is holding it up.
