Title (EN) SYSTEM, METHOD, AND MEDIUM TO UNLOCK AN OBJECT
(FR) SYSTÈME, PROCÉDÉ ET SUPPORT POUR DÉVERROUILLER UN OBJET
Abstract:
(EN) A mobile computing device captures an image of an identification code on an object that identifies the object, extracts the code from the image, and forwards the code and a user ID to a server, which responds with digital key when the user ID has been verified. The mobile computing device converts the digital key into a pulsed light sequence that represents the digital key. An unlocking device attached to the object detects the pulsed light sequence, recovers the digital key from the pulsed light sequence, compares the recovered digital key to a pre-stored digital key, and unlocks the device when the recovered digital key matches the pre-stored digital key.
(FR) Un dispositif informatique mobile capture une image d'un code d'identification sur un objet qui identifie l'objet, extrait le code de l'image, et transmet le code et un identifiant d'utilisateur à un serveur, qui répond avec une clé numérique lorsque l'identifiant d'utilisateur a été vérifié. Le dispositif informatique mobile convertit la clé numérique en une séquence de lumière pulsée qui représente la clé numérique. Un dispositif de déverrouillage fixé à l'objet détecte la séquence de lumière pulsée, récupère la clé numérique à partir de la séquence de lumière pulsée, compare la clé numérique récupérée à une clé numérique pré-stockée, et déverrouille le dispositif lorsque la clé numérique récupérée correspond à la clé numérique pré-stockée.
