Claim One:
1. A method for personal identification and authentication using face recognition and facial expression analysis comprising: conducting a stationary face recognition of a subject by a device for personal identification and authentication, wherein the device comprises one or more computer processors, a camera, and a display screen, wherein the stationary face recognition comprising: image-capturing the subject's face in a first captured image and verifying the first captured image is of a human face and identity of the subject by matching the first captured image against a database of pre-recorded face data records; conducting a facial expression test on the subject by the device, the facial expression test comprising: generating a random sequence of different facial expression requirements; and video-capturing the subject's facial expressions and analyzing the subject's facial expressions and comparing them against the generated facial expression requirements; conducting a continuous movement tracking test on the subject by the device, the continuous movement tracking test comprising: generating a random sequence of different movement requirements; and video-capturing the subject's movements and analyzing the subject's movements and comparing them against the generated movement requirements; and conducting a three-dimensional perspective check on the subject by the device, the three-dimensional perspective check comprising: obtaining two three-dimensional-perspective-check images of the subject's face at two different locations with respect to the device; locating two sets of facial landmarks in a first of the two three-dimensional-perspective-check images, wherein the two sets of facial landmarks lying on two different three-dimensional spatial planes in the first of the two three-dimensional-perspective-check images; locating the same two sets of facial landmarks in a second of the two three-dimensional-perspective-check images; estimating a three-dimensional spatial plane for each of the two sets of facial landmarks in the second of the two three-dimensional-perspective-check images; and calculating a relative displacement between the two three-dimensional spatial planes in the two three-dimensional-perspective-check images for determining the three-dimensional perspective check result.
