1. A method for detection of synthesized videos of humans, the method executed on one or more processors, the method comprising:
receiving a plurality of images of the skin of a human subject;
determining hemoglobin concentration (HC) changes from the plurality of images;
determining one or more blood flow patterns from the plurality of images based on the HC changes;
determining whether the one or more blood flow patterns are indicative of a synthesized video; and
outputting the determination of whether the blood flow patterns from the video are indicative of the synthesized video.
