Abstract
(EN)
Methods and devices for unlocking a lock mode are provided. The method includes receiving handwriting when receiving a request for unlocking a screen, providing a handwriting detection window, reading coordinate information of at least one or more strokes handwritten in the handwriting detection window, deriving first character information from the read coordinate information, and determining if the first character information are consistent with preset second character information, and if so, unlocking the screen; otherwise, keeping the screen locked.

L'invention concerne des procédés et des dispositifs de déverrouillage d'un mode de verrouillage. Le procédé consiste à recevoir une écriture manuscrite lors de la réception d'une requête demandant de déverrouiller un écran, à fournir une fenêtre de détection d'écriture manuscrite, à lire des informations de coordonnées d'au moins un ou plusieurs traits écrits à la main dans la fenêtre de détection d'écriture manuscrite, à obtenir des premières informations de caractère à partir des informations de coordonnées lues, et à déterminer si les premières informations de caractère sont ou non cohérentes avec des secondes informations de caractère préconfigurées, et si tel est le cas, à déverrouiller l'écran ; autrement, à garder l'écran verrouillé.
