Abstract

The present invention uses a first step of static facial recognition followed by facial expression testing, continuous motion tracking testing, and 3D perspective inspection to identify and authenticate objects, prevent photo spoofing and mask spoofing, and determine whether an object is alive people. This method requires the subject to place her face in front of a camera, which may be a built-in or peripheral camera of the mobile communication device. The method also entails displaying certain instructions and real-time video feedback of the subject's face to the subject on a display screen, which may be a display screen built into or peripheral to the mobile communication device or mobile computing device. 3D perspective inspection uses a single camera to take two images of a subject's face to calculate stereoscopic view data of the subject's face.
