Methods and Apparatus are provided for fake fingerprint detection. In one embodiment, an apparatus for determining validity of a fingerprint includes a prism having an imaging surface configured to be touched by a fingerprint, one or more light sources configured to produce an image based on a refractive index of a material presented in association with the fingerprint, one or more imaging sensors configured to capture the image, and a controller configured to determine validity of the fingerprint based on whether the image has been masked.
