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.

Claim (Index 9):
A method for spoofing detection in image biometrics, the method comprising:\n obtaining a sequences of images from a camera using computer hardware, 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, the environment being a three-dimensional space that is within a field of view of the camera; creating a marker for the representation of the body part using the computer hardware, the marker corresponding to a feature in the representation of the body part; identifying a feature of the environment of the user present during the second plurality of images in the sequence of images using the computer hardware; quantifying, using the computer hardware, a correlation between the marker and the feature of the environment in the sequence of images to produce a synchronicity metric of the degree to which the marker and the feature of the environment correlate; and providing, using the computer hardware, a spoofing attempt indication in response to the synchronicity metric being beyond a threshold.
