Abstract
the invention proposes a method and an associated system for authenticating a user, by means of the redundancy present between several images of a video, the method using garbled circuits, named variant garbled circuits, associated with the alternative bits between the images of the video and a garbled circuit named invariant garbled circuit, associated with the invariant bits between the images of the video, so that the invariant garbled circuit only needs to be evaluated a single time.
