A secure system using a continuously-changing key that depends on the user's body part. A system obtains an image of the user's fingerprint (105) and cements it according to a random generator (104). Only part of the image and not the entire image is sent atone time. The random segmentation insures that part of the image that is sent continuously varies from time to time. Therefore, an unauthorized receiver can receive only part but not the entire image. The fingerprint image part is verified by a remote agent (120).
L'invention concerne un système de sécurité utilisant une clé changeant continuellement qui dépend d'une partie du corps de l'utilisateur. Un système obtient une image de l'empreinte digitale (105) de l'utilisateur et la colle à un générateur aléatoire (104). Seule une partie de l'image, non l'image entière, est envoyée en une fois. La segmentation aléatoire assure que la partie de l'image continuellement envoyée varie de temps en temps. En conséquence, un destinataire non autorisé ne peut recevoir qu'une partie de l'image, non l'image entière. La partie image de l'empreinte digitale est vérifiée par un agent (120) à distance.
