Biometric authentication unit, automatic transaction processing device, biometric authentication method, and biometric authentication program

Abstract

Provided are a biometric authentication unit and automatic transaction processing device which suppress the occurrence of failures in biometric authentication as much as possible, for which the number of times for biometric authentication to be repeated is reduced even in case of failure, and which does not cause distrust to be directed thereto by a person to be authenticated. For a customer who is not used to biometric authentication, guidance for a suitable setting method for a biological body before starting of authentication is displayed. Then, if a predetermined assessment value for a degree of match is not reached upon performing of authentication processing, the possibility that the finger may not have been registered is warned, and checking for finger contamination / a bandaging / keratinization / movement is requested. In addition, when estimated factors for placement / location resulting in insufficient degree of match and an improvement plan are displayed so that the customer takes action for improvement, a block diagram is displayed in real-time for improvement indicating the portion for which there is a bad degree of match so as to facilitate confirmation of the results of improvement of the customer. Upon success of biometric authentication, the improvement history of the placement / location of the finger is stored into an IC card so that, by displaying thereof at the start of biometric authentication at the time of the next transaction, authentication failure is prevented.

Description

technical field [0001] The present invention relates to a biometric authentication unit, a biometric authentication method, a biometric authentication program, and an automatic transaction processing device including the biometric authentication unit that read the biometric information of a customer and perform identity verification. Background technique [0002] Conventionally, in financial institutions, for transactions performed through cash automatic teller machines (hereinafter referred to as ATMs) as automatic transaction processing devices, losses due to use of stolen cards, counterfeit cards, etc. have increased. As a method, a biometric authentication using biometric information for identity verification is being used. In the ATM, regardless of whether the user is the user himself or not, if the biometric authentication cannot be performed, the acceptance of the transaction is rejected. [0003] As a countermeasure against this problem, Patent Document 1 discloses ...

AI Technical Summary

Problems solved by technology

[0005] However, the biometric authentication system described in Patent Document 1 displays the cause and improvement plan when the biometric authentication cannot be performed, and when the user repositions the finger based on these, only a simple result of whether authentication is possible or not is output.

Therefore, the user does not know how the consistency changes

Moreover, if the user fails to obtain authentication even after repeated trials according to the improvement plan, the user may feel distrustful of the biometric authentication.
