摘要: Systems and techniques for user authentication are described. A portable electronic device can include an imaging sensor a motion sensor. Multiple images of face be acquired by using Motion information obtained Next, first vector determined based on the multiple images, second information. The then authenticated (1) determining similarity measure between vector, (2) performing facial recognition at least one images. Note that used to detect virtual-camera attack. Specifically, fail if is less than threshold.
