US Patent 10169646 Face authentication to mitigate spoofing

Embodiments provide, in at least one aspect, methods and systems that authenticate at least one face in at least one digital image using techniques to mitigate spoofing. For example, methods and systems trigger an image capture device to capture a sequence images of the user performing the sequence of one or more position requests based on the pitch and yaw movements. The methods and systems generate a series of face signatures for the sequence of images of the user performing the sequence of one or more position requests. The methods and systems compare the generated series of face signatures to stored face signatures corresponding to the requested sequence of the one or more position requests.
