System and method for a biometric image sensor with spoofing detection

摘要

The system includes a 3D biometric image sensor and processing module operable to generate a 3D surface map of a biometric object, wherein the 3D surface map includes a plurality of 3D coordinates. The system performs one or more anti-spoofing techniques to determine a fake biometric.

主权项

1. A system for anti-spoofing detection of a biometric object, comprising:
a biometric image sensor operable to capture one or more images of a 3D biometric object and generate biometric image data; and at least one processing device configured to:
process the biometric image data and perform at least a first anti-spoofing analysis, wherein the at least first anti-spoofing analysis includes at least one of: a color spectrum analysis; a reflectivity analysis; or a saturation analysis;determine one or more anomalies in the first anti-spoofing analysis; andin response to the one or more anomalies, determine to perform at least a second anti-spoofing analysis, wherein the at least second anti-spoofing analysis includes at least a different one of: a color spectrum analysis; a reflectivity analysis; or a saturation analysis.
