Abstract

L'invention concerne un appareil et un procédé de reconnaissance d'identité, ainsi qu'un support de mémorisation. Le procédé est appliqué à un réseau intelligent et comprend les étapes consistant à : obtenir une empreinte vocale (A) d'utilisateur pendant l'enregistrement d'un utilisateur ; obtenir une empreinte vocale (B) d'utilisateur lorsque l'utilisateur souhaite réaliser une transaction commerciale ; et reconnaître une identité de l'utilisateur en comparant l'empreinte vocale (A) à l'empreinte vocale (B). En utilisant un service réalisant une reconnaissance d'identité par le biais d'une empreinte vocale basée sur un réseau intelligent à large bande, le problème en l'état de la technique, selon lequel une technologie de reconnaissance d'empreinte vocale ne présente pas de procédé de mise en place de contrôle fiable et efficace dans le domaine du paiement mobile, est résolu. La collecte de données et le contrôle d'un terminal à un serveur peuvent être mis en place efficacement à l'aide d'un appel et un service intelligent d'un opérateur et le logiciel APP de transaction du terminal sont combinés, de sorte qu'un site Web d'hameçonnage et des virus ne puissent pas obtenir illégalement des informations d'utilisateur, ce qui fournit un environnement d'authentification d'identité fiable pour des transactions de grande valeur dans l'Internet mobile. En outre, une authentification d'identité plus fiable et unique est fournie par le biais de la reconnaissance d'empreinte vocale.
