According to an embodiment, a biometric reference information storage apparatus transmits, to the biometric reference information certificate generation apparatus, a biometric authentication context including the challenge information, the hash value of the biometric reference information, and a first digital signature. The biometric reference information certificate generation apparatus verifies the challenge information and the first digital signature. The biometric reference information certificate generation apparatus transmits a biometric reference information certificate to the biometric reference information storage apparatus. The biometric reference information storage apparatus writes the biometric reference information and the biometric reference information certificate in a storage module.

Biometric reference information registration system, apparatus, and program

An authentication device receives each authentication context including an output information block, an input information block, and an authenticator block. The output information block includes a process result and process result identification information. The input information block includes a process result and process result identification information. The authentication device verifies each authenticator block. The authentication device searches for the output information block having the same value of process result identification information as the value of process result identification information in the input information block from other authentication contexts based on process result identification information in the input information block included in each authentication context. The authentication device verifies whether or not the process result in the input information block is equal to the process result in the searched output information block, and authenticates that all the authentication contexts have validity when all the verification results are valid.

System and device for authentication

In an information communication system, user personal information is batch-managed in a user management center apparatus. The center apparatus issues temporary information, which includes temporary user information and temporary authentication information, in response to a log-in request from a user terminal apparatus that designates a net-shop apparatus, and sends the information to the user terminal apparatus and the designated net-shop apparatus. Thereby, if the user terminal apparatus sends an authentication request to the net-shop apparatus on the basis of the information, the net-shop apparatus can authenticate the user terminal apparatus on the basis of the information from the user management center apparatus. At this time, the user personal information does not go to the net-shop apparatus, and there is no need for the net-shop apparatus to manage the user personal information.

A client apparatus receives a message including a random number from a server apparatus during the handshake of agreement process, creates a biometric negotiation message including the biometric authentication method information and sends the biometric negotiation message to the server apparatus. Then, the client apparatus executes a biometric authentication based on biometric authentication method information notified from the server apparatus and encrypts the random number based on the private key. In addition, the client apparatus generates an authenticator from a result of the biometric authentication, the biometric authentication method information, the encrypted random number, and the client certificate, and sends to the server apparatus an authentication context including these. The server apparatus verifies the authentication context and establishes a secure session in one handshake.

Client apparatus, server apparatus, and program using entity authentication and biometric authentication

A configuration including, in authentication contexts, function unit identification information unique to the function unit that has executed an authentication subprocess in entity devices permits an authentication apparatus to specify the function unit that has executed the authentication subprocess in the entity devices. The verifier, therefore, can verify the legitimacy of the authentication subprocess from the authentication context even in the presence of a plurality of function units capable of executing the same authentication subprocess in the entity devices.

Authentication apparatus and entity device

A root-account management apparatus generates an electronic signature based on a survival condition and a secret key when an authentication result of a user of a client apparatus is proper, and transmits derived-account credence element information including the survival condition, the electronic signature and a public key certificate to a derived-account management apparatus. The derived-account management apparatus creates derived-account information which becomes valid when the survival condition is satisfied so that the derived-account information includes both the derived-account credence element information which becomes invalid when a validity term of the public key certificate expires and a biometric information template of the user which is valid regardless of this validity term. Accordingly, even if an authentication element as a root (public key certificate) becomes invalid, a derived authentication element (biometric information template) can be prevented from becoming invalid.

According to one embodiment of the present invention, the first authentication context includes the template certificate indicative of the validity of a template and the first apparatus evaluation certificate indicative of the validity of the first apparatus evaluating information while the second authentication context includes the second apparatus evaluating certificate indicative of the validity of the second apparatus evaluating information. And the template certificate and the first and second evaluation certificates are verified when verifying the first and second authentication contexts. Thus, the validity of the template used for authentication or the apparatus evaluating information included in the authentication context can be verified.

Verification apparatus and program

A client apparatus transmits environmental information acquired from an environmental information acquisition device as well as a biometric authentication information matching result to a server apparatus. The server apparatus verifies the validity of the environmental information such as a luminance as well as the validity of the biometric authentication information matching result. If an environment is problematic, the server apparatus notifies the client apparatus that the environmental information is problematic. The client apparatus overcomes the problem of the environment such as the luminance based on the notification from the server apparatus and then retries a biometric authentication. The possibility of re-failure due to the environmental problem can be reduced during a retry of the biometric authentication.

System, apparatus, and program for biometric authentication

A client device transmits service identification information to an authentication device at the time of a service request, prompts selection of one or more authentication entity devices which execute one or more authentication subprocesses from among all the authentication entity devices adaptive to profile information received from the authentication device, based on 'function list information defining an execution environment of each of the authentication entity devices', transmits a request for executing an authentication subprocess to such selected each authentication entity device, and transmits to the authentication device 'authentication context information including an execution environment and an execution result of an authentication subprocess' received from such each authentication entity device.

Authentication system, device, and program

Each of the embodiments of the present invention supplies date information issued from a third party to a digital signature of a first user apparatus for an electronic document. Originality of the electronic document is ensured by applying the digital signature of the third party to a set of the digital signature and date information. No electronic document is transmitted to the third party apparatus during originality assurance of the electronic document. Accordingly, it is possible to decrease loads to the third party and associated networks even if the third party apparatus is congested with accesses. Since there is registered an undeniable signature for a second user apparatus, it is possible to prevent the second user apparatus from denying the reception.
