RecognizeMe is a  jailbreak tweak, which will allow users to unlock their iPhone 4, just by looking at it.

As you can see in the demo video below, the jailbreak package promises to bring “biometric facial recognition security” to the iPhone 4. This means that users will be able to configure the handset to scan their own face in order to unlock the iPhone. Furthermore, it will be possible to adjust exactly “how sure” you want the app to be, in order to go ahead with the unlock (this ranges from “Not Secure” to “Very Secure”).

RecognizeMe is now available in Cydia for download for $6.99 via the BigBoss repository.
