Abstract
L'invention concerne un procédé d'authentification d'un visage présenté à un caméra temps de vol, comprenant les étapes dans lesquelles : - la caméra temps de vol acquiert (S02) une image et des informations spatiales d'un visage, les informations spatiales comprenant pour chaque pixel au moins une position dans l'espace d'un point correspondant du visage par rapport à la caméra temps-de-vol, l'image comprenant pour chaque pixel au moins une intensité lumineuse reçue, - à partir de l'intensité lumineuse reçue et des informations spatiales relatives à une zone d'intérêt regroupant au moins un point du visage, une unité de traitement détermine (S04) au moins un indicateur de réflectance locale, les informations spatiales comprenant une orientation correspondante du visage, - l'unité de traitement compare (S05) cet indicateur de réflectance locale à au moins un indicateur de référence, et authentifie le visage ou détecte une fraude.
