Public key certificate using system, public key certificate using method, information processing apparatus, and program providing medium
First Claim
1. A public-key certificate using system for using a public key certificate which functions, in association with digital signature data of a certificate authority added thereto, as a certificate of a public key for encryption processing, said system comprising:
- a person identification certificate authority which executes a person authentication by comparing sampling information which serves as person identification data of a person requesting a public key certificate against a template which serves as person identification data of the person requesting a public key certificate, the template being obtained from a person identification certificate possessed by said person identification certificate authority; and
a certificate authority which issues a public key certificate for the requesting person on condition that the person authentication is established.

Abstract
In a public key certificate using system, a template which serves as person identification data of a person requesting a public key certificate is obtained from a person identification certificate of the person, a person authentication is executed by comparing sampling information of the person against the template, and a public key certificate for the person is issued by a certificate authority on condition that the person authentication is established, thus reducing the load on the certificate authority for person authentication. The public key certificate issued to the user is deleted upon completion of a processing session involving use of the public key certificate, restricting the use of the public key certificate to the particular processing session.
