摘要： The present invention provides a novel configuration which allows devices capable of processing different signature algorithms to mutually verify public key certificates. In this configuration, public key certificates storing plural signatures based on different signature algorithms such as RSA and ECC are issued and each device selects a signature which can be processed (namely, verified) by itself and verifies the selected signature. Consequently, the novel configuration allows the devices each being capable of verifying only a different signature algorithm to verify the public key certificates of the other devices, so that each device can perform public key certificate verification in the cross-certification and encrypted data communication not only with the other devices having public key certificates attached with signatures based on the same signature algorithm as that of each device, but also with the other devices or providers having public key certificates attached with signatures based on different signature algorithms from that of each device, thereby significantly enhancing the reliability in communication.

摘要： A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.

摘要： Disclosed are an information processing apparatus and an information processing method which execute person authentication and allows various services such as receiving of contents to be received, provided that the authentication is successfully passed. In the information processing apparatus for executing, by a connection to an external server providing various services such as contents transmission, a process such as receiving of contents, person authentication is executed by comparing a template acquired from a person identification certificate storing a template which is person identification data of a user using the information processing apparatus with sampling information input by the user, and a connection to the external server is executed provided that the authentication is successfully passed. In addition, the person identification certificate and the public key certificate are stored in a memory together with link information in which the person identification certificate and the public key certificate applied during a process of establishing a connection to the server are related to each other.

摘要： 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.

摘要： A person authentication system, a person authentication method, an information processing apparatus, and a program providing medium authenticate a person who uses an information apparatus in data communication. A person authentication certificate storing a template which includes person authentication data is used in the person authentication system. A person authentication execution entity checks the validity of the certificate on the basis of a certificate expiration date, a certificate usage number limit, or a template expiration date in person authentication processing on the basis of the certificate. The person authentication is executed by comparing the template with sampling information input by a user if the validity is confirmed. A person identification certificate authority updates the certificate or the template according to the request of the entity or the authenticated person.

摘要： A user device receives the content, and pays a content fee, based on the usage control policy of the content, by electronic money up to the allowable amount of money set in an issue log. The user device then creates a usage log including a content identifier and sends it to a service provider. The service provider creates a receive log based on the usage log, and sends it to a clearing center. The clearing center performs settlement processing for the electronic money based on the receive log, and sends a transfer request to an account management institution. By performing the above-described series of processing by using encrypted data, the settlement of the content usage fee is safely performed.

摘要： A public-key-encryption data-communication system includes a public-key-certificate issuer authority. The public-key-certificate issuer authority performs the issuance of a public key certificate and management operations, certification of a subject to be certificated, which is a certificate issuing request, and management such as registration processing are executed by a root registration authority or each registration authority. The public-key-certificate issuer authority performs processing for validating, invalidating, and deleting the certificate in accordance with a request from the root registration authority. The root registration authority accepts a request for issuing a public key certificate corresponding to the subject to be certificated which is under the control of a certificated registration authority, and transfers it to the public-key-certificate issuer authority in a form in which a signature is added to it. Processes by the public-key-certificate issuer authority, the root registration authority, the registration authority are separated, whereby the need for new implementation of user recognition, certificate issuance, registration, and management is eliminated.
