Unlocking a personal device using unlock approaches like PIN, password or an unlock pattern is insecure, as it is prone to the shoulder surfing attack: an attacker watching the display during user authentication. Therefore, Face Unlock – using biometric face information for authentication – is an approach to a more secure personal device unlock. Unfortunately, when using frontal face information only, the authentication still can be circumvented by a photo attack: presenting a photo/video of the authorized person to the camera. We intend to create a Face Unlock which is harder to circumvent by using all face information that is available during a 180 degree pan shot around the user’s head. Based on stereo vision, 2D and depth images are recorded of the user’s head, along with sensor data of the device movement.
