Abstract
The present invention employs a first step of stationary face recognition, followed by a facial expression test, a continuous movement tracking test, and a 3D perspective check to identify and authenticate a subject, prevent photo spoofing and facemask spoofing, and determining whether the subject is a living person. The method requires a subject to present her face before a camera, which can be the built-in or peripheral camera of a mobile communication device. The method also requires displaying to the subject certain instructions and the real-time video feedback of the subject face on a display screen, which can be the built-in or peripheral display screen of the mobile communication device or mobile computing device. The 3D perspective check uses a single camera to take two images of the subject's face for the calculating the stereoscopic view data of the subject's face.
