Paper processing device and authentication algorithm updating program

Abstract

The invention provides a paper processing device, which can ensure paper authentication accuracy and can inhibit the increase of a false coupon list and inhibit the decrease of authentication processing efficiency based on a serial number. A main control part (10) reads an authentication algorithm (s21) from a CD disposed in a CD driver (18) and installs the authentication algorithm (s22). If the CD is recorded with a deletion list, the main control part (10) reads the deletion list (s24) from the CD. The main control part (10) reads the serial number and currency registered in the deletion list one by one. If a serial number black list is registered with serial numbers and currency which are consistent with the above serial numbers and currency, the serial numbers (s25-s28) will be deleted from the serial number black list.

Description

technical field [0001] The present invention relates to a paper processing device for distinguishing the authenticity of the paper by using the optical pattern or magnetic pattern and the serial number marked on the paper such as banknotes, checks, securities, etc. The feature quantity is used to identify the true and false identification algorithm to update the identification algorithm update program. Background technique [0002] Conventionally, there are paper sheet processing devices that process paper sheets such as banknotes, checks, and securities. The paper sheet processing apparatus discriminates, for each sheet of paper to be processed, whether the paper is a genuine bill or a counterfeit bill (hereinafter referred to as a counterfeit bill). For example, an automatic teller machine (hereinafter referred to as ATM) installed in a storefront of a financial institution such as a bank detects the optical pattern or magnetic pattern of the banknote as a feature value f...

AI Technical Summary

Problems solved by technology

In other words, useless serial numbers (serial numbers that have become useless) are also registered in the counterfeit coupon blacklist, so there is a problem that its size is unnecessarily increased (enlarged)

[0013] In addition, the ATM compares the serial number of the banknote it read with all the serial numbers registered in the counterfeit banknote list, thereby performing authenticity identification based on the serial number. Therefore, it is registered in the counterfeit banknote blacklist The serial number increases, and the time required for true and false identification increases

That is, if the ATM also registers the serial number that has become useless in the counterfeit bill blacklist, then there is a problem that the time required for authenticity identification based on the serial number increases and the processing efficiency decreases.
