As reported by Business Insider Apple has filed a patent for a facial recognition system for mobile devices.
It is similar to the system in Android phones, however Apple is considering incorporating an option into the software which would recognize a number of faces, detected through the camera of the phone, which would be capable of starting the iOS device.
Future builds of the iOS software are supposed to detect how attentive you are to your mobile phone, so be careful how you look at your iPhone if you want it to co-operate.
After the privacy debate over Facebook facial recognition technology, privacy experts will probably be wondering how long it will be before your smartphone becomes smart enough to not only see you and detect your mood and attentiveness but capture pictures of you and start circulating your photo around social networking sites.
The software powering the iOS feature will hopefull be opt in. Mobile phones and similar devices such as iPads with in-built digital camera technology raise new privacy issues ranging from the problem of taking and publishing photographs without consent to location based detection tools and security concerns.
