Abstract: An authentication system includes a plurality of authentication apparatuses, each of which includes first biological information of a same set of users; a crosschecking unit for crosschecking input biological information with a part of the first biological information; a transmitter for assigning second biological information included in the first biological information other than the part of the first biological information to the other authentication apparatuses without assigning same information in the second biological information to other authentication apparatuses, and to request the other authentication apparatuses to crosscheck the input biological information with the assigned second biological information; and a receiver for receiving, from the one or more other authentication apparatuses, one or more results of crosschecking the input biological information with the assigned second biological information by the one or more other authentication apparatuses in response to the requesting.

Abstract: When first biometric information is read with an ID number, a first authentication unit acquires second biometric information corresponding to the ID number from a first database, and authenticates when the first biometric information matches with the second biometric information. A transferring unit transfers the second biometric information from the first database to a second database when the authentication is successful. When the first biometric information is read without the ID number, a second authentication unit authenticates if at least one of the second biometric information in the second database matches with the first biometric information among.

Abstract: In a personal authentication device, a storing unit of each group stores therein biometric information of the persons belonging to that group. When a subject is to be authenticated, an acquiring unit acquires subject biometric information that is biometric information of the subject. A collating unit decides whether the subject is authentic based on whether there is a match for the subject biometric information in the biometric information in the storing unit. If the subject is determined to be not authentic, the subject biometric information is collated with biometric information in the storing unit of another group.

Abstract: Authorized persons are recognized based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons. When a person provides his identifier, biological information corresponding to the provided identifier is retrieved from the database and writing in a storage unit. Then, when the person provides his biological information, it is checked whether provided biological information matches with the biological information in the storage unit. When the two match, the person is recognized as an authorized person.

Abstract: In a biometric authentication device that includes biometric-authentication-data generating means for generating biometric authentication data from biometric data of a user, and authentication means for performing authentication of the biometric authentication data on the basis of reference biometric data of the user, a matching ratio of the reference biometric data and updated and registered second reference biometric data is calculated, and the user is requested to re-register the reference biometric data and the second reference biometric data when the matching ratio is lower than a predetermined threshold value.

Abstract: An information processing system using biometrics authentication employ biometrics characteristics for individual authentication to enable accessing of individual information, with which the convenience of input for users is improved. A biometrics database which links and stores group numbers, individual identification numbers, and biometrics data is provided, and a group number is used to read biometrics data for the group, which is verified against detected biometrics data to identify the individual identification number and access an individual database. Even if a user sets a group number which is not easily forgotten, biometrics authentication can be used to execute individual authentication with high accuracy, and moreover secure individual information access is possible.

Abstract: The disclosed biological information deleting method and system reliably delete biological information and execute a service withdrawal process by implementing a user terminal and a member management apparatus networked together. Machine readable media have programs of instructions for executing the service withdrawal process. The member server executes the service withdrawal process upon notification of the end of the deletion of a user's biological information which is stored in either an IC card or at a user terminal.

Abstract: Authorized persons are recognized based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons. When a person provides his identifier, biological information corresponding to the provided identifier is retrieved from the database and writing in a storage unit. Then, when the person provides his biological information, it is checked whether provided biological information matches with the biological information in the storage unit. When the two match, the person is recognized as an authorized person.

Abstract: To provide a technology that prevents a rental for a defrauding purpose by specifying a borrower through biometric authentication and conducting the authentication based on a usage past record of the borrower. Biometric information of a borrower is received from the terminal, a blacklist recorded with biometric information of beware-of persons is referred to, authentication as to whether the biometric information of the borrower matches with the blacklist or not is done, a past record database recoded with the biometric information of the borrowers having usage past records is referred to, there is made the authentication as to whether the biometric information of the borrower who does not match with the blacklist matches with the past record database or not, the terminal is notified of approval or non-approval for a rental operation on the basis of results of the authentication, the past record database is updated if the rental operation is approved.

Abstract: An authentication system comprises a plurality of authentication devices connected one another via a communication line. A user inputs biological information in the first authentication device. The input biological information is registered in the first authentication device and also is transmitted to the authentication devices from the first authentication device. The transmitted biological information is respectively registered in each of the authentication devices. Upon conducting identity verification of a user, each of the authentication devices checks the biological information newly input by the user with the biological information registered in the authentication device.
