Claim One:
1. A system for spoofing detection in image biometrics, the method comprising: a camera to obtain a sequences of images, 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 sensor being a camera, the environment being a three-dimensional space that is within a field of view of the camera; a biometric feature detector to create a marker for the representation of the body part, the marker corresponding to a feature in the representation of the body part; an environmental feature detector to identify a feature of the environment of the user present during second plurality of images in the sequence of images, wherein to identify the feature of the environment includes an emitter of the system to emit a pattern into the environment, the pattern comprising a first component in a visible light spectrum and a second component in an infrared light spectrum, wherein the feature of the environment includes a reflectivity of the pattern, including the first component and the second component, in an area of the environment containing the marker; a synchronicity detector to quantify 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, wherein the correlation between the marker and the feature of the environment includes a degree to which the reflectivity of the pattern in the first component in the visible light spectrum and the second component in the infrared list spectrum differ from each other; and a spoofing indication controller to provide a spoofing attempt indication in response to the synchronicity metric being beyond a threshold, wherein the threshold is based on a reflectivity divergence such that divergent reflectivity between infrared and visible light with infrared being lower indicates a spoofing attempt and divergent reflectivity between infrared and visible light with visible light being lower indicates liveness.
