Abstract

La présente invention concerne un système et un procédé d'authentification à base de points multiples configurable. Le système 101 comprend un dispositif utilisateur 102, qui comprend un ou plusieurs capteurs 103, un processeur 104 et une mémoire 106. Le système 101 comprend un réglage, d'une taille d'une matrice de points, la taille de la matrice pouvant être modifiée de manière dynamique. Le système 101 comprend, l'habilitation de l'utilisateur pour qu'il dessine un motif en touchant un ou plusieurs points dans la matrice, chaque point unique étant apte à se répéter dans le motif une ou plusieurs fois et à reconnaître, le motif dessiné en tant que motif de déverrouillage. Le système 101 comprend l'habilitation de l'utilisateur pour qu'il dessine le motif à chaque fois avant le processus d'authentification afin de déverrouiller le dispositif utilisateur 102, la comparaison du motif dessiné avec le motif de déverrouillage défini par l'utilisateur et le déverrouillage du dispositif utilisateur 102 si le motif dessiné correspond au motif de déverrouillage défini par l'utilisateur.
