Biometric authentication apparatus and biometric authentication method

Abstract

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.

Description

technical field [0001] Embodiments discussed herein relate to biometric authentication devices, biometric authentication methods, and biometric authentication computer programs. Background technique [0002] In recent years, biometric authentication technologies have been developed, which use biometric information such as fingerprints or palm vein patterns to determine whether to authenticate an individual. Biometric authentication technology has been widely used in the following ranges: from large-scale systems with a large number of registered users such as access control systems, border control systems, or systems using ID numbers to devices used by specific individuals such as computers or mobile terminals . [0003] The biometric authentication technology is classified into a so-called 1:1 authentication method and a 1:N authentication method. In the 1:1 authentication method, identification information of a user requesting authentication such as a user name or an ide...

AI Technical Summary

Problems solved by technology

However, when the system executes processing for deleting registered biological information during execution of biometric authentication processing, execution of the deletion processing may cause execution of biometric authentication processing to be delayed

This delay is undesirable as it prolongs the wait time from when the user enters biometrics until the authentication result is obtained
