Perhaps the most interesting aspect of the system would be the ability for the device’s settings to be customized depending on the user. For example, when detecting a specific user, iOS could set personalized wallpapers, notification settings, and custom configurations for apps(ipad tips: dvd to ipad). This would provide multiple user logins, allowing iOS users to easily share a device among family or coworkers.

Apple’s system would differ from other face recognition systems by ignoring face biometrics. As PatentlyApple explained, “The face recognition techniques are based on a simple, weighted difference map, rather than traditional (and computationally expensive) correlation matching.” Apple’s system could detect “high information portions” of a face such as the eyes, mouth, or the tip of a nose. In addition, an “orange-distance filter” could be applied to determine variations in skin tone and detect the “likely presence” of a user. This could detect the distance between the device and the user’s face, as well as the user’s “level of attentiveness.”

Apple's patent was filed in June, 2010, soon after the first iPad was introduced(ipad tips: convert dvd to ipad). Face recognition as a security measure, however, has some possible flaws. Google's Android recently introduced a Face Unlock feature as well, but reports have suggested it can be fooled by a photograph of the user.
