Abstract

L'invention concerne un procédé et un dispositif d'identification d'une signature, un terminal mobile et un serveur en nuage. Le procédé comprend les étapes suivantes : recevoir des informations de signature; comparer les informations de signature à une signature prédéfinie acquise auprès d'un serveur en nuage; si les informations de signature correspondent à la signature prédéfinie à un niveau de correspondance prédéfini, déterminer que les informations de signature sont une signature authentique. Dans l'invention, la signature prédéfinie est acquise auprès du serveur en nuage où la signature prédéfinie est stockée et ne peut pas être volée facilement. Lorsqu'un utilisateur saisit une signature, le procédé compare la signature saisie reçue à la signature prédéfinie pour déterminer si la signature est une signature authentique. Le procédé peut facilement identifier une signature falsifiée, améliorer l'expérience de l'utilisateur et résoudre le problème dans l'état de la technique selon lequel comme de plus en plus de transactions sont réalisées sur des terminaux intelligents grâce à une signature, une fois que la signature d'un utilisateur est falsifiée, l'utilisateur subira certainement des pertes.
