Abstract

L'invention concerne un procédé de déverrouillage de contrôle d'accès basé sur la reconnaissance biométrique et un appareil, un dispositif et un support de déverrouillage de contrôle d'accès, le procédé comprenant les étapes suivantes consistant à : recevoir des informations de diffusion d'un routeur, acquérir des informations de dispositif nouvellement connecté dans les informations de diffusion et comparer les informations de dispositif nouvellement connecté avec chaque information d'identification prédéfinie d'un ensemble d'identification prédéfini (S10) ; si des informations d'identification cibles correspondant aux informations de dispositif nouvellement connecté existent dans l'ensemble d'identification prédéfini, acquérir des informations biométriques d'un demandeur de déverrouillage (S20) ; comparer les informations biométriques avec des informations de déverrouillage cibles correspondant aux informations d'identification cibles (S30) ; si les informations biométriques correspondent aux informations de déverrouillage cibles, effectuer une opération de déverrouillage d'un contrôle d'accès (S40). L'invention permet ainsi d'améliorer l'efficacité et la sécurité du déverrouillage de contrôle d'accès basé sur la reconnaissance biométrique.
