Abstract: A biometric authentication device performs authentication of a user based on biometric information. In the biometric authentication device, a registry information storage stores pre-registered biometric information as registry information. An acceptance value determiner determines a verification acceptance value used for authentication, based on quality of the registry information with regard to reliability of characterizing an individual. An authentication information acquirer obtains biometric information of a user as authentication information. A similarity calculator compares the authentication information of the user with the registry information and calculates similarity between the authentication information and the registry information. An authenticator identifies whether the user is a registrant corresponding to the registry information, based on the similarity and the verification acceptance value.

Abstract: A card processing apparatus is provided with: a storage unit for storing biological information read by a biological information acquiring unit as a result of comparing biological information read from a card by a card handling unit with the biological information read from a user by the biological information acquiring unit, a confirmation is made that the user is an owner of the card; and a control unit for judging whether storing operations for storing the biological information in the storage unit have been carried out preselected times, for producing biological information stored in another card newly issued by employing a plurality of biological information stored in the storage unit when the storing operations have been carried out the preselected times, and for instructing the user to again acquire biological information when the storing operations have not yet been carried out the preselected times.

Abstract: This comprises a storage that stores second partial authentication data that is part of the authentication data and that is the remainder of the first partial authentication data stored in another device, and second partial processing data that is part of the processing data used when doing the process of matching the input data with the authentication data and which is the remainder of the first partial processing data stored in the other device; a receiver that receives the first partial authentication data and the first partial processing data; a data linker that generates the authentication data from the first partial authentication data and the second partial authentication data and that generates the processing data from the first partial processing data and the second partial processing data; and an authentication module that performs authentication by executing the process of matching the input data with the authentication data.
