JP5602674B2 - Paper sheet processing apparatus and identification algorithm update program - Google Patents

Description

  The present invention discriminates the authenticity of paper sheets such as banknotes, checks, securities, etc., based on feature quantities such as optical patterns and magnetic patterns of paper sheets, and serial numbers written on the paper sheets. The present invention relates to a sheet processing apparatus and an identification algorithm update program for updating an identification algorithm for identifying authenticity with a feature amount of a sheet.

  Conventionally, there is a paper sheet processing apparatus that processes paper sheets such as banknotes, checks, and securities. The paper sheet processing apparatus identifies, for each paper sheet to be handled, whether the paper sheet is a genuine note or a forged ticket (hereinafter referred to as a fake ticket). For example, an automated teller machine (hereinafter referred to as ATM) installed in a bank or other financial institution detects the optical pattern or magnetic pattern of the banknote as a feature amount for each banknote handled. The authenticity of the paper sheet is identified by the feature amount.

  In addition, ATM uses a serial number to identify a banknote (counterfeit) that cannot be identified as a counterfeit note using a feature amount of the optical pattern or magnetic pattern detected from the bill. It is carried out. Specifically, the ATM stores a fake ticket blacklist in which serial numbers written on fake tickets are registered, and collates serial numbers written on banknotes with serial numbers registered in the fake ticket blacklist. To identify authenticity.

  In addition, the financial institution is notified of the serial number of the counterfeit ticket in which a related organization such as the police is found. If the banknote (fake note) for which the serial number is notified cannot be identified as a counterfeit by the feature amount of the optical pattern or magnetic pattern detected from the banknote at that time, the financial institution will falsely indicate the serial number. Register on the ticket blacklist.

  Furthermore, based on the serial number written on the banknote, a device for judging whether it is a stolen banknote (see Patent Document 1), reads two serial numbers written on the banknote, and the characters of these two serial numbers A device that determines the match between columns and serial numbers (see Patent Document 2), checks whether papers with the same serial number are present in a plurality of devices at the same time, and is not registered in the false ticket blacklist There is also an apparatus (see Patent Document 3) that can identify a fake ticket with a serial number.

  However, as described above, the financial institution puts in the counterfeit bill blacklist the serial number of the counterfeit note that cannot be identified as a counterfeit note based on the feature amount of the optical pattern or magnetic pattern detected from the note at the time of discovery. In addition to the additional registration, we are developing an identification algorithm that can properly identify a counterfeit note by using the feature values of the optical pattern and magnetic pattern detected from the counterfeit note. Then, the identification algorithm installed in the ATM is updated to the developed identification algorithm. Therefore, in ATM, the serial number registered in the counterfeit bill blacklist is updated to an identification algorithm that can properly identify that the counterfeit bill with the serial number is a counterfeit using the feature amount of the optical pattern or magnetic pattern. When it is done, it becomes unnecessary.

  The counterfeit ticket blacklist did not delete the registered serial numbers of the counterfeit tickets that were no longer needed, but only increased the serial numbers cumulatively. That is, the fake ticket blacklist has a problem that a useless serial number (an unnecessary serial number) is also registered, so that the size thereof is uselessly large (enlarges).

  In addition, since ATM recognizes authenticity by serial number by comparing the serial number of the read banknote with all serial numbers registered in the counterfeit ticket list, it is registered in the counterfeit ticket blacklist. As the serial number increases, the time required to identify authenticity increases. That is, when the serial numbers that are no longer necessary are registered in the counterfeit black list, the ATM has a problem that the time required for authenticating the authenticity by the serial numbers increases and the processing efficiency decreases.

  An object of the present invention is a paper that ensures identification accuracy for identifying the authenticity of a paper sheet, and suppresses a reduction in processing efficiency associated with the enlargement of a counterfeit bill list and the identification of authenticity by a serial number. A leaf processing apparatus and an identification algorithm update program are provided.

  The paper sheet processing apparatus of the present invention is configured as follows in order to solve the above problems and achieve the object.

  The feature amount detection unit detects the feature amount of the paper sheet. The feature amount detection unit detects, for example, an optical pattern (reflected light pattern, transmitted light pattern) of a paper sheet or a magnetic pattern as a feature amount. The identification unit identifies the authenticity of the paper sheet by using the installed identification algorithm, using the feature amount detected by the feature amount detection unit. The identification unit, for example, the similarity between the feature value detected from the paper sheet and the feature value of the genuine note stored in advance, the feature value detected from the paper sheet, and the fake ticket stored in advance And the feature amount of the paper sheet is calculated, and the authenticity of the paper sheet is identified based on the calculated similarity.

  The serial number recognition unit recognizes the serial number written on the paper sheet. The determination unit determines whether the serial number recognized by the serial number recognition unit is registered in the fake ticket list in which the serial number of the fake ticket stored in the storage unit is registered.

  Therefore, even if it is a paper sheet (fake ticket) that cannot be identified as a fake ticket by the identification algorithm installed from the feature quantity of the paper sheet, the fake ticket whose serial number is registered in the fake ticket list Can be identified as a fake ticket.

In addition, when the identification algorithm updating unit updates the identification algorithm, the updated identification algorithm allows the identification unit to identify a paper sheet (fake ticket) that can be identified as a fake ticket in the fake ticket list. Delete the registered serial number. In other words, when the identification algorithm for identifying authenticity is updated using the feature amount of the optical pattern or magnetic pattern detected from the paper sheet, the counterfeit note that can be identified as a fake note by the updated identification algorithm Delete the serial number from the fake ticket list .

Registration Specifically, the identification algorithm updating unit, together with the identification algorithm to update the serial number of the counterfeit note, and version identification algorithm that can identify the counterfeit banknotes to be counterfeit, in association with a A fake ticket that can be identified as a fake ticket with a version of the identification algorithm before the update, and that can be identified with a version of the identification algorithm after the update. The serial number is extracted from the deletion list. That is, it extracts a serial number of a fake ticket that could not be identified as an identification algorithm fake ticket before update and that can be identified as an identification algorithm fake ticket after update. And the identification algorithm update part deletes the serial number of the fake ticket extracted here from the fake ticket list. Therefore, it is possible to prevent the serial numbers that are no longer required from being registered in the counterfeit ticket list from being wasted, and to suppress the enlargement of the counterfeit ticket list and the reduction in processing efficiency for authenticating the authenticity by the serial number.

  According to the present invention, it is possible to prevent a serial number that is no longer required from being registered in a counterfeit ticket list from being wasted, and to suppress an increase in the counterfeit ticket list and a reduction in processing efficiency related to authenticity identification by the serial number. be able to.

The banknote recognition unit 30 includes a control unit 31, an optical sensor 32, a magnetic sensor 33, a serial number recognition unit 34, an identification unit 35, a storage unit 36, and an input / output unit 37.

  The optical sensor 32 detects reflected light or transmitted light of the light irradiated on the banknote, acquires an optical pattern of the banknote, and acquires an image of the banknote. The image is not limited to the entire banknote as long as the banknote includes an area where the serial number is written. The bill recognition unit 30 may be configured to perform the acquisition of the optical pattern and the acquisition of the image with the same optical sensor 32, or the optical sensor 32 that acquires the optical pattern and the optical sensor 32 that acquires the image. May be provided individually.

  The banknote identification unit 30 identifies the denomination and authenticity of the banknote based on the optical pattern and magnetic pattern read from the banknote, but the main control unit 10 performs authenticity identification based on the serial number. .

  FIG. 5 is a diagram showing a serial number black list. This serial number blacklist is stored in the storage unit 19. As shown in FIG. 5, the serial number black list registers a serial number written on a counterfeit ticket and a denomination for each counterfeit ticket in association with each other. The denomination is a combination of a pass code defined in ISO 4217 (in the case of Japanese yen: JPY) and an amount of money.

  Hereinafter, the operation of the ATM 1 of this embodiment will be described.

  FIG. 6 is a flowchart showing the processing for adding a counterfeit note to the serial number blacklist. Notify the financial institution of the serial number and denomination of the counterfeit ticket found by the police and other related organizations. The financial institution can identify all the ATMs 1 connected to the host device 5 from the host device 5 via the network 6 and all the ATMs 1 through the network 6 so that all the ATMs 1 can be identified. Broadcasts additional registration requests including seeds.

  When the ATM 1 receives the additional registration request transmitted from the host device 5 in the communication unit 17 (s1), the ATM 1 reads one fake ticket serial number and denomination included in the additional registration request received this time. (S2), it is determined whether or not the fake ticket is unregistered in the serial number blacklist (s3). If it is a fake ticket that is not registered in the serial number black list, ATM1 registers the serial number and denomination of the fake ticket read in s2 in the serial number black list (s4). If the ATM 1 is a fake ticket registered in the serial number black list, the serial number and denomination of the fake ticket read in s2 are not registered in the serial number black list (the process relating to s4 is not performed). ATM1 determines whether the processing after s2 mentioned above was performed about the serial number and denomination of all the fake tickets included in the additional registration request received this time (s5). If ATM1 determines that there is an unprocessed counterfeit serial number and denomination at s5, it returns to s2 and repeats the above-described processing. If the ATM 1 determines that there is no serial number and denomination of the unprocessed counterfeit in s5, the process is terminated.

  This additional registration request does not have to be transmitted for a fake ticket whose serial number and denomination have already been transmitted to ATM1. That is, it is only necessary to transmit the serial number and denomination only for the counterfeit ticket that has been recently notified from the related organizations such as the police and the serial number and denomination have not been transmitted to the ATM 1 at this time.

  Since various transaction processes such as deposit transaction and withdrawal transaction in ATM 1 are known, detailed description thereof will be omitted here, but only banknote identification process will be briefly described.

  FIG. 7 is a flowchart showing the identification process. The banknote processing unit 12 reads the optical pattern and magnetic pattern of the banknote for each banknote transported along the banknote transport path 27 in the banknote recognition unit 30 (s11). The banknote recognition unit 30 reads the optical pattern of the banknote with the optical sensor 32 and reads the magnetic pattern of the banknote with the magnetic sensor 33.

  The banknote identification unit 30 identifies the denomination and authenticity of the banknote based on the installed identification algorithm (s12). In s12, the optical pattern and magnetic pattern of the banknote read in s11 are collated with the optical pattern and magnetic pattern of genuine bills registered in advance, respectively, and the degree of similarity is calculated. Then, when the similarity of the optical pattern exceeds a predetermined optical threshold and the similarity of the magnetic pattern exceeds a predetermined magnetic threshold, it is identified as a genuine note. Also, s12 is a process for identifying a genuine note on the condition that it is also verified that it is not a fake note based on the similarity between the optical pattern and the magnetic pattern of the fake note registered in advance. Also good.

  When the banknote identification unit 30 recognizes that it is a genuine note from the feature amount of the banknote in s12, the serial number recognition unit 34 recognizes the serial number written on the banknote from the image of the banknote read by the optical sensor 32. (S13, s14). The banknote identification unit 30 notifies the main control unit 10 of the serial number recognized in s14. The main control unit 10 determines whether or not the serial number notified from the banknote identification unit 30 is registered in the serial number blacklist (s15), and if not registered, it is identified as a genuine note (s16). . On the contrary, if it is registered, it is identified as a fake ticket (s17).

  In addition, if it identifies that it is not a genuine note from the feature-value of a banknote in s12, it will identify as a fake note in s17 (s17).

  In this way, even if the installed identification algorithm is a fake ticket that cannot accurately identify authenticity with the optical pattern and magnetic pattern of the bill, the fake ticket whose serial number is registered in the serial number blacklist Can be identified as a fake ticket by the serial number written on the banknote.

  Moreover, since the serial number currently described is not recognized about the banknote identified by the collation of an optical pattern and a magnetic pattern, the processing load in the serial number recognition part 34 can also be reduced.

  Next, the operation at the time of updating the identification algorithm will be described. Here, a case where the identification algorithm to be updated is recorded on a CD will be described as an example. In this CD, a deletion list shown in FIG. 8 is recorded in addition to the identification algorithm to be updated. This deletion list is a list in which the denominations of counterfeits that can be identified by this identification algorithm are associated with serial numbers.

  FIG. 9 is a flowchart showing the operation when the identification algorithm is updated. A program for updating the identification algorithm is stored in the storage unit 19. The main control unit 10 reads the identification algorithm recorded on the CD from the CD set in the CD drive 18 (s21), and installs this identification algorithm (s22). When the installation of the identification algorithm is completed, the main control unit 10 checks whether or not the deletion list is recorded on the CD set in the CD drive 18 (s23). If the deletion list is not recorded, the main control unit 10 performs this process. finish.

  When the deletion list is recorded on the CD set in the CD drive 18, the main control unit 10 reads the deletion list from the CD (s24). The main control unit 10 reads one serial number and denomination registered in the read deletion list (s25), and determines whether the serial number and the denomination match are registered in the serial number black list. Determine (s26). If a match is registered in the serial number black list, the main control unit 10 deletes the serial number from the serial number black list (s27). The main control unit 10 determines whether or not the processing after s25 has been executed for all serial numbers registered in the deletion list (s28). When determining that there is an unprocessed serial number in s28, the main control unit 10 returns to s2 and repeats the above-described processing. When determining that there is no unprocessed serial number in s28, the main control unit 10 ends this process.

  Therefore, the serial number is deleted from the serial number black list for a counterfeit ticket that can be authenticated by the updated identification algorithm. For this reason, it is possible to prevent the serial number blacklist from storing the serial numbers of fake tickets in vain. That is, the serial number blacklist can be prevented from being enlarged. In addition, it is possible to suppress waste of time required for determining the authenticity of banknotes by serial numbers, and to suppress a decrease in processing efficiency.

  The deletion list in the above example may be as shown in FIG. This deletion list associates the version of the identification algorithm in addition to the counterfeit denomination and serial number. This version of the identification algorithm is a version capable of identifying the counterfeit ticket associated with the version.

  FIG. 11 is a flowchart showing the operation at the time of updating the identification algorithm according to this example. Prior to updating the identification algorithm, the main control unit 10 determines the version of the installed identification algorithm (s31). Thereafter, the main control unit 10 reads the identification algorithm recorded on the CD from the CD set in the CD drive 18 (s32), and installs this identification algorithm (s33). When the installation of the identification algorithm is completed, the main control unit 10 checks whether or not the deletion list is recorded on the CD set in the CD drive 18 (s34). If the deletion list is not recorded, the main control unit 10 performs this process. finish.

  When the deletion list is recorded on the CD set in the CD drive 18, the main control unit 10 reads the deletion list from the CD (s35). Of the serial numbers registered in the deletion list read out in s35, the main control unit 10 cannot be a counterfeit ticket with the version identification algorithm before the update, and is a counterfeit card with the version identification algorithm after the update. All the serial numbers and denominations associated with the serial numbers are extracted (s36).

  In s36, all the serial numbers and denominations in which the associated version X satisfies the following conditions are extracted.

Condition: Version before update <X ≦ Version after update For example, if the version of the identification algorithm before update is “3” and the version of the identification algorithm after update is “4”, the version “4” is associated. All serial numbers and denominations are extracted. If the version of the identification algorithm before update is “2” and the version of the identification algorithm after update is “4”, the serial number associated with the version “3” or “4” and the denomination are changed. Extract all. Here, the version of the identification algorithm is indicated by an integer.

  The main control unit 10 reads one serial number and denomination extracted in s36 (s37), and determines whether the serial number and the denomination match are registered in the serial number black list (s38). . If a match is registered in the serial number black list, the main control unit 10 deletes the serial number from the serial number black list (s39). The main control unit 10 determines whether or not the processing after s37 has been executed for all the serial numbers extracted in s36 (s40). When determining that there is an unprocessed serial number in s40, the main control unit 10 returns to s2 and repeats the above-described processing. When determining that there is no unprocessed serial number in s28, the main control unit 10 ends this process.

  According to this configuration, the same effect as the above-described example can be obtained, and the time required for the process of deleting the serial number of the counterfeit note that is no longer necessary from the serial number blacklist can be shortened.

  In the above example, the identification algorithm to be updated and the deletion list are recorded on the CD and set in the CD drive 18 so as to be read by ATM1. The apparatus 5 may be configured to deliver to each ATM 1.

  The present invention is not limited to banknotes, and can be applied to a paper sheet processing apparatus that processes other types of paper sheets such as checks and securities.
