Abstract: A user authentication system and method. The user authentication system includes a camera and a processor connected to the camera. The processor receives images from the camera, searches for a user feature in the images, determines if the images require correction, adjusts camera controls in a pre-defined order to provide desired corrections, applies the desired corrections to subsequent images and authenticates the user based on the user feature in the corrected images.

Abstract: System and techniques for spoofing detection in image biometrics are described herein. A sequence of images may be obtained from a camera; a first plurality of images in the sequence of images including a representation of a user body part, and a second plurality of images in the sequence of images including a representation of an environment of the user. A marker may be created for the representation of the body part. A feature of the environment of the user present during the second plurality of images may be identified in the sequence of images using a third group of circuits. A correlation between the marker and the feature of the environment in the sequence of images may be quantified to produce a synchronicity metric of the degree to which the marker and the feature of the environment correlate.

Abstract: Systems and techniques for facial spoofing detection in image based biometrics are described herein. A marker may be created for a representation of a face in a first plurality of images of a sequence of images. The marker corresponds to a facial feature of the face. An environmental feature of an environment of the face may be identified across a second plurality of images of the sequence of images. A correlation between the marker and the environmental feature in the sequence of images may be quantified to produce a synchronicity metric. A spoofing attempt may be indicated in response to the synchronicity metric meeting a threshold.

Abstract: A system and method for capturing an image of a user. An image is captured with a camera, wherein the image includes a user's image. A first avatar is displayed in a display, wherein displaying includes positioning an avatar in at least some of the user's image. The user is then encouraged to move so the first avatar moves to a second position in the display.
