Abstract
(EN)
Systems, methods, and apparatuses of using biometric information to authenticate a first device of a user to a second device are described herein. A method includes storing, by the first device, a first key share of a private key and a first template share of a biometric template of the user. The second device stores a public key, and one or more other devices of the user store other key shares and other template shares. The first device receives a challenge message from the second device, measures biometric features of the user to obtain a measurement vector, and sends the measurement vector and the challenge message to the other devices. The first device receives partial computations, generated using a respective template share, key share, and the challenge message, from the other devices, uses them to generate a signature of the challenge message and send the signature to the second device.

Systèmes, procédés et appareils d'utilisation d'informations biométriques pour authentifier un premier dispositif d'un utilisateur vers un second dispositif. Un procédé comprend le stockage, par le premier dispositif, d'un premier partage de clé d'une clé privée et d'un premier partage de modèle d'un modèle biométrique de l'utilisateur. Le second dispositif stocke une clé publique, et un ou plusieurs autres dispositifs de l'utilisateur stockent d'autres partages de clé et d'autres partages de modèle. Le premier dispositif reçoit un message de défi en provenance du second dispositif, mesure des caractéristiques biométriques de l'utilisateur pour obtenir un vecteur de mesure, et envoie le vecteur de mesure et le message de défi aux autres dispositifs. Le premier dispositif reçoit des calculs partiels, générés à l'aide d'un partage de modèle et d'un partage de clé respectifs, et le message de défi, provenant des autres dispositifs, les utilise pour générer une signature du message de défi et envoyer la signature au second dispositif.
