Authentication verifying method, authentication verifying member and authentication verifying member producing method

摘要

Authentication verifying for an object to be certified is carried out. An authentication verifying chip in which authentication verifying information is stored is mounted non-removably on a certificate. A confirmation chip in which the authentication verifying information is encrypted by a crypt key of a certificate issuer and is stored is mounted non-removably on the object to be certified. When verifying the authenticity of the object to be certified, the encrypted authentication verifying information in the confirmation chip is decrypted by the crypt key of the certificate issuer, and it is compared to the authentication verifying information in the authentication verifying chip.

主权项

1. An authentication verifying system, comprising:
a set of a certificate and an object to be certified; an authentication verifying chip non-removably mounted on said certificate and storing first authentication verifying information which is obtained by chance and is copy-unable; and said object to be certified being mounted non-removably a storage medium, where said first authentication verifying information is encrypted using a first crypt key of authorities that issue the certificate and certify the object to generate encrypted-by-first-crypt-key first authentication verifying information that is stored, wherein, said first authentication verifying information and said encrypted-by-first-crypt-key first authentication verifying information are read; said encrypted-by-first-crypt-key first authentication verifying information is decrypted by using the first crypt key of said authorities; and the corresponding relation between said certificate and said object to be certified is confirmed by comparing said first authentication verifying information thus read with said decrypted first authentication verifying information as decrypted from said encrypted-by-first-crypt-key first authentication verifying information.
