Abstract

L'invention concerne un procédé d'identification, un appareil, un dispositif électronique et un support de stockage lisible par ordinateur, ledit procédé consistant : à obtenir des premières informations biométriques d'un objet à identifier et, selon les premières informations biométriques, à effectuer une première identification sur l'objet à identifier (S101) ; en réponse à la réussite de la première identification, à obtenir des secondes informations biométriques de l'objet à identifier (S102) ; selon les secondes informations biométriques, à effectuer une seconde identification sur l'objet à identifier (S103). Sans augmenter la complexité opérationnelle, il est possible d'améliorer efficacement la précision de l'identification et d'améliorer ainsi la sécurité d'un système de sécurité et d'améliorer l'expérience utilisateur.
