Even if the user obtains the medium on which the two-dimensional coded password is described (recorded), unauthorized access is not easy (almost impossible) unless the authorized user verifies the "ordering" information. In the case of extremely sophisticated confidential information, the password is split between the person in charge and his / her boss in the first half and the second half, and the management system must be read if two people do not continue reading in the same operation. If the system is not authenticated, security will be further improved.

Dimensionally coded and printed on the surface of the certificate. Certificate's Card Purpose-Depending on the personality, use only this digital signature X and not the conventional visual analog handwriting signature Y.

Abstract

Procédé d'identification individuelle par des codes cryptés à deux dimensions, système hybride d'authentification de personne individuelle et système d'identification de personne hors ligne. Le contenu de codes à deux dimensions représentant des informations de corps individuel cryptées est enregistré en tant qu'information d'image. Des informations spécifiques de la personne individuelle en tant que moyen de reconnaissance de la personne individuelle sont composées de codes cryptés en deux dimensions. L'«ordre de disposition» de codes en deux dimensions mélangés en éléments factices est fait hors ligne, indépendamment des informations lues sur carte et des entrées en ligne. Des données singulières créées par le fait que des données d'image, par ex. une signature, sont soumises à un traitement numérique sont ajoutées aux données créées par cryptage des informations spécifiques de la personne individuelle en tant que moyens d'authentification de la personne individuelle. Les données résultantes sont transformées en codes en deux dimensions qui sont imprimés sur un document tel qu'un certificat. De cette manière, lorsque des informations spécifiques d'une personne individuelle telles qu'un certificat sont reproduites, les données d'image telles qu'une signature sont détectées et reproduites sur la base des données singulières. La personne peut ainsi être identifiée sans vérification en ligne.
