1. A method of performing a biometric measurement on an individual, the method comprising:
- disposing a containment film between a skin site of the individual and a platen;
directing light through the containment film to the skin site to illuminate the skin site under a plurality of distinct optical conditions;
receiving light scattered from the skin site for the plurality of optical conditions;
deriving a multispectral image of the skin site from the received light; and
performing a biometric function with the derived multispectral image.

Abstract
Methods and systems for performing a biometric measurement on an individual are disclosed. A containment film is disposed between a skin site of the individual and a platen. Light is directed through the containment film to the skin site to illuminate the skin site under multiple distinct optical conditions. Light scattered from the skin site is received for the multiple optical conditions. A multispectral image of the skin site is derived from the received light. A biometric function is performed with the derived multispectral image.

12. A biometric system comprising:
-
a platen; a thin film substantially transparent to the light disposed above the platen and configured to receive a biometric from an individual; one or more illumination sources configured to direct light through the platen and the thin film; and a detector configured to receive light reflected from the biometric through the thin film and the platen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
