Abstract
Methods and apparatus are described for performing a biometric function on a purported skin site. The site is illuminated under distinct optical conditions and light reflected from the site is received. A feature value for several features is derived from the received light, permitting a comparison to be performed with reference feature values. Whether the purported skin site is a true skin site is determined from the comparison.
