Abstract:
Methods and systems are provided for performing a biometric function. A purported skin site of an individual is illuminated with white light. Light scattered from the purported skin site is received with a color imager on which the received light is incident. Spatially distributed images of the purported skin site are derived and correspond to different volumes of illuminated tissue of the individual. The images are analyzed to perform the biometric function.
