RecognizeMe just hits the Cydia store. For who don't know RecognizeMe is a magical Cydia tweak which brings the first real face recognition to iOS devices that has front facing camera. Specifically instead of entering passcode on lockscreen, you just have to use facial recognition technology.
RecognizeMe is the first Facial Recognition security for the iPhone. Although not perfect, RecognizeMe does a pretty good job at facial recognition, given optimal conditions. RecognizeMe sits on the iPhone passcode screen, so it serves as an alternate to, rather than a replacement for the passcode.RecognizeMe is available via Cydia store under BigBoss repository for $6.99.
