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.

Embodiment 1

[0049] (1) Registration processing

[0050] To start a transaction by biometric authentication processing, the customer 205 needs to apply to the financial institution for registration of biometric information. There are two ways of registering the biometric information: registering the biometric information of the customer 205 in a server of a financial institution and registering the biometric information in a portable electronic medium such as an IC card 201 carried by the customer 205 . Next, a case where the biometric information is registered in the IC card 201 as the customer's portable electronic medium will be described.

[0051] The financial institution issues the IC card 201 by writing the cash card's financial institution number, branch number, customer's account number, etc. into the magnetic stripe or IC chip 301 as account information data 407, and mails it to the customer 205. The customer 205 brings the received IC card 201 to the financial institution. The...

[0090] (1) Method of registration processing, authentication processing

[0091] Figure 10 Showing the vein image 702 of the finger 701 read at the time of registration, the biometric information reading area is divided not only into one screen as a whole, but also divided into up and down / left and right, etc., feature extraction is performed in each divided area, and registered as registration data. (a) is full data, (b) is upper right data, (c) is upper left data, (d) is lower right data, (e) is lower left data. Figure 10 (b)-(e) 4-divided area, but may also be 2-divided up and down or left and right, or 3-divided up, middle and down. in addition, Figure 10 The regions in (b)-(e) overlap, but may be divided without overlapping.

[0092] In addition, in the slope adjustment of the central axis of the image, the entire data and the divided data are set as a set, and the slope difference between the central axis of the registration data and the authentication data is adju...

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...
