Biometric authentication device and biometric authentication method

Abstract

A biometric authentication device including: a storage unit that stores identification information and authentication information of a plurality of registrants; a deletion processing unit that, when receiving a request for deleting the authentication information of any one of the plurality of registrants, registering the identification information of the registrant to the deletion list, and deleting the authentication information of the registrant corresponding to the identification information registered on the deletion list from the storage unit at a predetermined time; and an authentication processing unit which is based on each registrant The authentication information and the authentication information extracted from the biological data representing the user's biological information to match the biological information of the multiple registrants with the biological information of the user to determine whether the user is authenticated as one of the multiple registrants Any registrant other than the registrant 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
