Abstract

La présente invention concerne un procédé, un système et un dispositif électronique de déverrouillage à reconnaissance faciale basée sur l'image. Le procédé selon l'invention comprend les étapes consistant à : prédéfinir au moins deux images faciales en tant que code de passe de déverrouillage d'image, et stocker les deux images faciales ; afficher de multiples images faciales sur une interface d'écran verrouillée pour une sélection d'utilisateur lors du déverrouillage ; comparer l'image faciale sélectionnée et la séquence de sélection avec le code de passe de déverrouillage d'image au moment du déverrouillage, en déterminant si l'image faciale sélectionnée et la séquence de sélection correspondent au code de passe de déverrouillage d'image ; si c'est le cas, le déverrouillage réussit, sinon, indiquer que le déverrouillage échoue. La présente invention peut réaliser un déverrouillage sur la base des multiples images faciales stockées dans un dispositif, et une mauvaise sélection d'image ou une séquence de sélection incorrecte sont toutes deux traitées en tant que code de passe de déverrouillage d'image erroné. La présente invention est hautement sécurisée, présente un fonctionnement simple et intuitif, et ne requiert pas qu'un utilisateur acquière une image instantanée avant chaque déverrouillage, ce qui facilite l'utilisation.
