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.

La présente invention a trait à des procédés et des systèmes pour la réalisation d'une fonction biométrique. Un site concerné de la peau d'une personne est éclairé dans des conditions optiques distinctes lors d'une unique session d'éclairage pour une position fixe du site concerné de la peau. La lumière en provenance du site concerné de la peau est reçu pour chaque condition optique. Des images du site concerné de la peau sont générées à partir de la lumière reçue. Les images sont analysées en vue de l'identification d'une caractéristique biométrique. Le fonction biométrique est mise en oeuvre en conformité avec une identification de la caractéristique biométrique.
