Face Unlock – Android: Facial Recognition Security Feature
Pretty cool feature!
…Just in case, there’s a redundant security layer from the swipe pattern or pass code if the software cannot recognize you at various entries (especially in the dark). After you set up the original image, you can improve the recognition software by taking further pictures of you (for instance) with glasses on/off, in different lighting, or at different camera angles. It will be interesting to see how this technology progresses.
