Biometric authentication processing system

Abstract

The invention provides a biometric authentication processing system. When the reading quality during the authentication process is less than a predetermined level of quality, image processing to improve the quality of a read image that is not performed during the registration process is performed to improve the image quality, thus making the biometric authentication successful. Software to improve the image quality is added by upgrading the version of the authentication software to successively add image improvement software to the authentication software irrespective of the registration process. This version upgrading method enables changes to be made to enhance the authentication success rate regardless of the version of the registration software. Further, an area in which to read biometric information during the registration process is set larger than that in which to read biometric information during the authentication process, so that if a subject body part is placed slightly deviated from a correct position, a matching check can still be made. The biometric information reading area is not only used as an entire single image but divided into sub-areas, in each of which characteristic quantities are extracted. According to the result of a matching check in each divided sub-area, an overall authentication result is determined as either OK or NG. Since which of the divided sub-areas is NG can be known, NG causes can be analyzed precisely.

Description

technical field [0001] The present invention relates to a biometric authentication processing system having a biometric authentication function for identifying the identity of a customer by reading biometric information of a customer. Background technique [0002] In a financial transaction between a financial institution and a customer, the financial institution starts the transaction by performing identity verification of the customer. For example, in the case of transactions at an automatic transaction machine (ATM), identity authentication is performed using a cash card and a password. In recent years, in the transactions of financial institutions, damages due to the use of stolen cards or counterfeit cards have increased, and especially for transactions at ATMs, there has been a strong demand for increased security. [0003] As a method for improving security, the IC chip of the card issued by the financial institution registers the customer's biometric information suc...

Problems solved by technology

As a result, if there is a problem with the quality of the read image, not the customer, but the quality of the read image, it is impossible to give appropriate advice, which constitutes an inappropriate advice, or the number of cases of rejections during reading cannot be sufficiently reduced.

[0014] In the device using the biometric authentication technology of the above-mentioned Patent Document 3, for the customer whose authentication failure (NG) occurs frequently in the reading of the biometric information, the registration is performed again based on the fact that the NG frequency is high, but there is no mention of analyzing the NG. The reason or prompt the customer to the reason of NG or its analysis result, so that the customer can improve
