Approaches utilize image information to not only identify a user, but also verify that the user is actually a physical person and not a false representation of that user. For example, a computing device can utilize image information with a facial recognition process in order to verify an identity of a current user of the device. A fingerprint or other verification metric can be generated from the image information and can be used to verify that the user is actually a physical human user instead of a representation (e.g., photo) of a human user. The fingerprint can include a number of cues, such as a shape of the face, a stereo disparity signature of the face, facial feature movement, as well as a presence of a human pulse. The cues can be combined and utilized for authenticating a user into the device as well as for verifying that the user is actually a physical person and not a false representation of that user.
