    摘要： According to the present invention, a method of biometric authentication comprises, storing information corresponding to a plurality of users in association with first reference biometric data and second reference biometric data, the users being divided into first and second groups, the quality of the first reference biometric data of each of the users in the first group being not less than a predetermined level, the quality of the first reference biometric data of each of the users in the second group being less than the predetermined level, obtaining first biometric data of a user by inputting first biometric information of the user, providing first authentication, obtaining second biometric data of a user by inputting second biometric information of the user when the first authentication indicates presumed matching of the first biometric data with the first biometric reference data of one of the users in the second group and providing second authentication. The present invention achieving high-speed and high-compatibility rate biometric authentication, even if the user is incompatible with the high-speed authentication method.

    摘要： A terminal (10) used for authentication is equipped with a biometric data storing unit (1) for storing therein various kinds of biometric data associated with the user of the terminal, and a sensor (2) for acquiring biometric data. When transmission of the biometric data necessary for authentication is requested from an authentication device, the user's biometric data is entered through the sensor (2) and, after the user's identity has been authenticated at the terminal (10), the biometric data requested by the authentication device is retrieved, from the biometric data storing unit (1), and transmitted to the authentication device.

    摘要： An uneven surface data detection apparatus for detecting an uneven surface, such as a human finger, having projected portions and recessed portions. A transparent base having upper and lower surfaces and an upper surface defining an uneven surface contact portion is provided, and a light is incident on the uneven surface so that the light derived from the recess portions enters to the transparent base and comes out thereof. However, a part of the light derived from the projected portions is totally reflected at least one time by the lower opposite surface and focussing lens is integrally formed on the transparent base so that the totally reflected light is drawn out of transparent base and enters to an image sensor.

    摘要： A biometric authentication apparatus includes: a storage unit which stores identification information and authentication information of a plurality of registrants; a deletion process unit which registers, when receiving a request to delete the authentication information of any of the plurality of registrants, the identification information of the registrant to a deletion list, and deletes, from the storage unit, the authentication information of the registrant corresponding to the identification information registered on the deletion list at predetermined time; and an authentication process unit which matches the biometric information of the plurality of registrants with biometric information of a user based on the authentication information of each registrant and authentication information extracted from biometric data representing the biometric information of the user to determine whether or not to authenticate the user as any of the plurality of registrants other than the registrants corresponding to the identification information registered on the deletion list.
