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: 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.

Abstract: An authentication device enabling access from multiple directions, comprises a biometric information acquirer that acquires biometric information from a biometric target; a detector that detects direction of access by the biometric target; a memory that stores in advance therein a template for authentication; and an authenticator that authenticates the biometric target on the basis of the detected access direction information of the biometric target, biometric information acquired from the biometric target, and the template. The authenticator performs authentication using access direction information for the biometric target by carrying out conversion of acquired biometric information or the template, so that the access direction at the time of biometric information acquisition matches the access direction at the time the authentication template was acquired.

Abstract: At startup, divided data blocks are received from other authentication devices and are assembled together with the local divided data block to reconstitute first authentication data. After a prescribed time interval, divided data blocks are again received from other authentication devices and are assembled together with the local divided data block to reconstitute second authentication data.

Abstract: A form sheet type determining method and apparatus for determining to which of predetermined form sheets an input form sheet corresponds. A plurality of sets of keywords are registered in a keyword register with one set of keywords for each predetermined form sheet type; image data of an input form sheet is read, character strings are extracted from the read image data, and character recognition is performed on each extracted character string; each of the character recognized strings is extracted as a keyword; the extracted keywords are collated, for each form sheet type, with the sets of keywords registered in the keyword register, thereby to determine the type of the input form sheet.
