Abstract
Methods and Apparatus are provided for fake fingerprint detection. In one embodiment, an apparatus for fake fingerprint detection includes a prism having a first side configured to be touched by a fingerprint, an IR LED located near the second side of the prism, a light source located near the third side of the prism, where both the IR LED and the light source are configured to illuminate the fingerprint simultaneously to produce a captured image of the fingerprint, one or more lenses configured to direct the captured image of the fingerprint for storage, one or more CMOS sensors configured to collect the captured image of the fingerprint for analysis, and a controller configured to determine validity of the fingerprint using the captured image.
