Abstract

La présente invention concerne un système et un procédé d'identification de l'utilisateur mettant en oeuvre des données de caractéristiques du pied. Le procédé de l'invention consiste à mesurer des informations du pied, à extraire des données de caractéristiques du pied sur la base des informations du pied mesurées. Les données de caractéristiques du pied extraites peuvent être utilisées pour identifier un utilisateur en fonction de différences anatomiques entre individus. Selon l'invention, l'utilisateur d'un système peut obtenir sans inconvénient des informations d'identification de l'utilisateur pendant qu'il s'emploie à une autre tâche. Les données de caractéristiques du pied peuvent en outre être utilisées pour vérifier l'identité d'un utilisateur dans divers services supplémentaires, tels que les soins de santé, la commande d'accès, etc.
