Network authentication system, method, and program, service providing apparatus, certificate authority, and user terminal

A service providing apparatus for use in a network authentication system in which when authentication is to be performed by using biometrical information of a user himself or herself between a user terminal and said service providing apparatus connected by a communication network, the authentication is performed on the basis of that certification of the validity of a collation result from said user terminal, which is performed by a certificate authority connected via the communication network,

• wherein in response to notification of the result of user collation performed using the biometrical information of the user in said user terminal, said service providing apparatus requests said certificate authority via the communication network to certify the validity of the collation result and, if the validity of the collation result is certified by a certificate notified from said certificate authority, provides a predetermined service to the user on the basis of the collation result contained in the certificate.

A certificate authority for use in a network authentication system in which when authentication is to be performed using biometrical information of a user himself or herself between a user terminal and a service providing apparatus connected by a communication network, the authentication is performed on the basis of that certification of the validity of a collation result from said user terminal, which is performed by said certificate authority connected via the communication network,

• wherein when, in response to notification of the result of user collation performed using the biometrical information of the user in said user terminal, requested to certify the validity of the collation result by said service providing apparatus via the communication network, said certificate authority certifies the validity of the collation result and notifies a certificate containing the collation result across the communication network, thereby allowing said service providing apparatus to provide a predetermined service to the user on the basis of the collation result contained in the certificate.

A user terminal for use in a network authentication system in which authentication is to be performed using biometrical information of a user himself or herself between said user terminal and a service providing apparatus connected by a communication network, the authentication is performed on the basis of that certification of the validity of a collation result from said user terminal, which is performed by a certificate authority connected via the communication network,

• wherein said user terminal identifies the user by collation by using the biometrical information of the user, notifies the collation result to said service providing apparatus via the communication network, thereby allowing said service providing apparatus to request, in response to this notification of the collation result from said user terminal, said certificate authority across the communication network to certify the validity of the collation result, receives a certificate which is notified from said certificate authority in response to the request and which certifies the validity of the collation result, and allows said service providing apparatus to provide a predetermined service to the user on the basis of the collation result contained in the certificate.

A network authentication method in which when authentication is to be performed by using biometrical information of a user himself or herself between a user terminal and a service providing apparatus connected by a communication network, the authentication is performed on the basis of that certification of the validity of a collation result from the user terminal, which is performed by a certificate authority connected via the communication network,

• wherein in response to notification of the result of user collation performed using the biometrical information of the user in the user terminal, the service providing apparatus requests the certificate authority via the communication network to certify the validity of the collation result and, if the validity of the collation result is certified by a certificate notified from the certificate authority, provides a predetermined service to the user on the basis of the collation result contained in the certificate.

• wherein when, in response to notification of the result of user collation performed using the biometrical information of the user in the user terminal, requested to certify the validity of the collation result by the service providing apparatus via the communication network, the certificate authority certifies the validity of the collation result and notifies a certificate containing the collation result across the communication network, thereby allowing the service providing apparatus to provide a predetermined service to the user on the basis of the collation result contained in the certificate.

A network authentication method in which authentication is to be performed using biometrical information of a user himself or herself between a user terminal and a service providing apparatus connected by a communication network, the authentication is performed on the basis of that certification of the validity of a collation result in the user terminal, which is performed by a certificate authority connected via the communication network,

• wherein the user terminal identifies the user by collation by using the biometrical information of the user, notifies the collation result to the service providing apparatus via the communication network, thereby allowing the service providing apparatus to request, in response to this notification of the collation result from the user terminal, the certificate authority via the communication network to certify the validity of the collation result, receives a certificate which is notified from the certificate authority in response to the request and which certifies the validity of the collation result, and allows the service providing apparatus to provide a predetermined service to the user on the basis of the collation result contained in the certificate.

A certificate authority for use in a network authentication system in which when authentication of a user is to be performed between a user terminal and a service providing apparatus connected by a communication network, said certificate authority connected via the communication network authenticates the validity of a collation result from said user terminal,

• wherein when, in response to notification of the result of user collation performed using the biometrical information of the user in said user terminal, requested to certify the validity of the collation result by said service providing apparatus across the communication network, said certificate authority certifies the validity of the collation result and notifies a certificate containing the collation result via the communication network, thereby allowing said service providing apparatus to provide a predetermined service to the user on the basis of the collation result contained in the certificate.

A service providing apparatus for use in a network authentication system in which when authentication of a user is to be performed between a user terminal and said service providing apparatus connected by a communication network, a certificate authority connected via the communication network authenticates the validity of a collation result from said user terminal,

• wherein in response to the result of user collation performed using the biometrical information of the user in said user terminal, said service providing apparatus requests said certificate authority via the communication network to certify the validity of the collation result, and provides a predetermined service to the user on the basis of the collation result contained in a certificate notified from said certificate authority in response to the request.
