Abstract
Methods and systems are provided for performing a biometric function. A purported skin site of an individual is illuminated under distinct optical conditions during a single illumination session for a fixed position of the purported skin site. Light from the purported skin site is received for each of the optical conditions. Images of the purported skin site are generated from the received light. The images are analyzed to identify a biometric feature as a characteristic in a portion of at least one of the images. The biometric function is implemented in accordance with an identification of the biometric feature.
