Claim:
1. A system for facial spoofing detection in image based biometrics, the method comprising: a biometric feature detector to create a marker for a representation of a face in a first plurality of images of a sequence of images, the marker corresponding to a facial feature; an environmental feature detector to identify an environmental feature of an environment of the face across a second plurality of images of the sequence of images, wherein the environmental feature includes edges detected in the second plurality of images, wherein the edges are moving edges, and wherein the edges define a convex hull; a synchronicity detector to quantify a correlation between the marker and the environmental feature in the sequence of images to produce a synchronicity metric, wherein the convex hull does not include the marker resulting in the synchronicity metric being reduced; and a spoofing indication controller to indicate a spoofing attempt in response to the synchronicity metric meeting a threshold.
