Description

Technical Field

[0001] The present invention relates to an apparatus, a system, a method, and a program for detecting counterfeit banknotes.

Background Art

[0002] Conventionally, apparatuses and systems for detecting counterfeit banknotes are known.

[0003] For example, there is known an apparatus for detecting counterfeit banknotes by detecting the paper quality of banknotes, the width and / or length of banknotes with an optical sensor, or detecting magnetic ink used in banknotes with a magnetic sensor.

[0004] Also, in Patent Document 1, a banknote handling apparatus reads the number of deposited banknotes and transmits it to a computer server, and the computer server collates the transmitted banknote number with the banknote numbers registered in a database (such as numbers known as counterfeit banknotes), and when the same banknote number as the transmitted banknote number is registered in the database, a system for determining that there is a possibility of a counterfeit banknote is disclosed.

[0005] Also, in Patent Document 2, a system is disclosed in which a server receives the serial number of a banknote read by a reading device, the reading time, the position information of the reading device, etc. from the reading device and stores them in an information storage unit. In this system, when the same serial number as the received serial number already exists in the information storage unit, the server acquires from the information storage unit the position information of the reading device that previously read this same serial number and the reading time of the serial number by this reading device, and the time required to move between the position specified by the received position information and the position specified by the acquired position information (required time), and the time difference between the received reading time and the acquired reading time (reading time difference), and when the grasped required time is greater than the grasped reading time difference, information indicating that the same serial number exists and information indicating the possibility of forgery are transmitted to the reading device.

Prior Art Documents

[0006] [Patent Document 1] Japanese Patent Publication No. 2003-303367 [Patent Document 2] Japanese Patent Publication No. 2009-116798 [Overview of the project] [Problems that the invention aims to solve]

[0007] As the precision of counterfeit banknotes improves, detecting counterfeit banknotes using optical or magnetic sensors becomes more difficult.

[0008] Furthermore, in the system described in Patent Document 2, the accuracy of detecting counterfeit banknotes decreases in the following cases. At the offices of security transport operators that collect cash such as sales proceeds from stores, banknotes read by readers such as inspection machines (collected banknotes) are almost always placed in a vault and then moved to the destination. Therefore, the time required from when the banknotes are read by the reader to when they are read by the reader at the destination is longer than the time required for transportation. Consequently, in such cases, the accuracy of detecting counterfeit banknotes decreases in the system described in Patent Document 2.

[0009] In view of the above circumstances, the present invention aims to provide a counterfeit banknote detection device, a counterfeit banknote detection system, a counterfeit banknote detection method, and a counterfeit banknote detection program that improve the accuracy of counterfeit banknote detection. [Means for solving the problem]

[0010] One aspect of the device is a counterfeit banknote detection device characterized by comprising: a storage unit that stores serial number information of issued banknotes; a reading unit that reads serial number information of collected banknotes; a matching unit that compares the serial number information of the collected banknotes read by the reading unit with the serial number information of the issued banknotes stored in the storage unit; a registration unit that, as a result of the matching by the matching unit, stores in the storage unit the same serial number information as the serial number information of the collected banknotes read by the reading unit, registers information including the serial number information of the collected banknotes and the scheduled issuance date of the collected banknotes in a database; an acquisition unit that, as a result of the matching by the matching unit, stores in the storage unit the same serial number information as the serial number information of the collected banknotes read by the reading unit, obtains the previous scheduled issuance date of the collected banknotes from the database; and a discrimination unit that, if the collection date of the collected banknotes is earlier than the previous scheduled issuance date of the collected banknotes obtained by the acquisition unit, identifies the collected banknotes as counterfeit banknotes.

[0012] One aspect of the method is a counterfeit banknote detection method characterized by the processor reading the serial number information of a collected banknote, comparing the read serial number information of the collected banknote with the serial number information of an issued banknote stored in a memory unit, registering information including the serial number information of the collected banknote and the scheduled issuance date of the collected banknote in a database if the same serial number information as the read serial number information of the collected banknote is stored in the memory unit as a result of the comparison, obtaining the previous scheduled issuance date of the collected banknote from the database, and if the collection date of the collected banknote is earlier than the obtained previous scheduled issuance date of the collected banknote, the processor performs a process to determine that the collected banknote is a counterfeit banknote.

[0013] One aspect of the program is a counterfeit banknote detection program characterized by reading the serial number information of a collected banknote, comparing the read serial number information of the collected banknote with the serial number information of an issued banknote stored in a memory unit, registering information including the serial number information of the collected banknote and the scheduled issuance date of the collected banknote in a database if the same serial number information as the read serial number information of the collected banknote is stored in the memory unit as a result of the comparison, obtaining the previous scheduled issuance date of the collected banknote from the database, and causing the processor to execute a process to determine that the collected banknote is a counterfeit banknote if the collection date of the collected banknote is earlier than the obtained previous scheduled issuance date of the collected banknote. [Effects of the Invention]

[0014] According to the present invention, the accuracy of detecting counterfeit banknotes can be improved. [Brief explanation of the drawing]

[0015] [Figure 1] This diagram illustrates the configuration of a counterfeit banknote detection system. [Figure 2] This diagram illustrates the functional configuration of a precision inspection machine. [Figure 3] This diagram illustrates the hardware configuration of a precision inspection machine. [Figure 4] This flowchart illustrates the process of detecting counterfeit banknotes performed by a verification machine. [Figure 5] It is a diagram illustrating an inspection result master in which inspection result information is registered.

Embodiment for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0017] FIG. 1 is a diagram illustrating the configuration of a counterfeit banknote detection system.

[0018] The counterfeit banknote detection system 1 illustrated in FIG. 1 includes a plurality of inspection machines 10 and a database server (hereinafter referred to as "DB server") 20. Each inspection machine 10 and the DB server 20 are connected to a communication network 30 by wire or wirelessly and can communicate via the communication network 30.

[0019] The inspection machine 10 is installed, for example, at each business office of a security transportation company that collects cash such as sales money from stores and conducts inspections on the collected cash. The inspection machine 10 has a counterfeit banknote detection function and also determines whether the collected banknotes are counterfeit banknotes when inspecting the collected cash. Note that the inspection machine 10 is an example of a counterfeit banknote detection device. The DB server 20 includes a database (hereinafter referred to as "DB") 21 having a serial number master (serial number master table) 21a and an inspection result master (inspection result master table) 21b. The communication network 30 includes a wired and / or wireless communication network and is, for example, a communication network including a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, or a dedicated network.

[0020] FIG. 2 is a diagram illustrating the functional configuration of an inspection machine. Note that the functional configuration of the inspection machine 10 illustrated in FIG. 2 shows only the functional configuration related to the counterfeit banknote detection function.

[0021] The inspection machine 10 illustrated in FIG. 2 includes a storage unit 11, a reading unit 12, a collation unit 13, a registration unit 14, an acquisition unit 15, and a discrimination unit 16.

[0022] The storage unit 11 stores the serial number information of issued banknotes. The reading unit 12 reads the serial number information of collected banknotes. The verification unit 13 verifies the serial number information of the collected banknotes read by the reading unit 12 with the serial number information of the issued banknotes stored in the storage unit 11. If the verification by the verification unit 13 finds that the serial number information of the collected banknotes read by the reading unit 12 is the same as the serial number information of the collected banknotes stored in the storage unit 11, the registration unit 14 registers information including the serial number information of the collected banknotes and the scheduled release date of the collected banknotes in DB 21 (verification result master 21b). Here, the scheduled release date is the date on which the collected banknotes read by the reading unit 12 are expected to be deposited into the vault and subsequently released from the vault. The vault is located in the business premises where the verification machine 10 is installed, and the collected banknotes released from the vault are promptly delivered (transported) to the destination (transportation destination). The acquisition unit 15 retrieves the previous scheduled release date of the collected banknotes from DB 21 (verification result master 21b) if the serial number information of the collected banknotes read by the reading unit 12 is the same as the serial number information stored in the storage unit 11 as a result of verification by the verification unit 13. The discrimination unit 16 identifies the collected banknotes as counterfeit if the collection date of the collected banknotes is earlier than the previous scheduled release date of the collected banknotes retrieved by the acquisition unit 15.

[0023] Furthermore, if the discrimination unit 16 determines that the collected banknotes are counterfeit, the registration unit 14 may add an alert flag to the information registered in DB 21 (examination result master 21b) by the registration unit 14, and also remove the scheduled issuance date of the collected banknotes from that information.

[0024] Furthermore, if the verification by the verification unit 13 reveals that the serial number information of the collected banknote read by the reading unit 12 is not the same as the serial number information stored in the storage unit 11, the discrimination unit 16 may determine that the collected banknote is a counterfeit banknote, and the registration unit 14 may register information including the serial number information of the collected banknote and an alert flag in the DB 21 (verification result master 21b).

[0025] Alternatively, the serial number information of issued banknotes stored in the memory unit 11 may be obtained from DB 21 (serial number master 21a).

[0026] Figure 3 illustrates the hardware configuration of the inspection machine.

[0027] The inspection machine 10 illustrated in Figure 3 includes a control unit 110, a display input unit 120, and a cash handling unit 130.

[0028] The control unit 110 includes a processor 111, RAM (Random Access Memory) 112, a communication interface 113, a graphics processing unit 114, a storage device 115, and an input / output interface 116, which are interconnected by a bus 117.

[0029] The processor 111 may be a single processor, a multi-processor, or a multi-core processor. The processor 111 controls various parts of the inspection machine 10 by executing various programs (including counterfeit banknote detection programs), such as OS (Operating System) programs and application programs.

[0030] RAM112 temporarily stores a portion of the program executed by processor 111 and is also used as working memory for processor 111.

[0031] The communication interface 113 is connected to the communication network 30 and communicates with an external device (e.g., DB server 20) via the communication network 30.

[0032] The graphics processing unit 114 is connected to the display device 121 of the display input unit 120, and displays various screens on the display device 121 according to control signals from the processor 111.

[0033] The storage device 115 is, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs and data executed by the processor 111.

[0034] The input / output interface 116 is connected to the touch panel 122 of the display input unit 120 and the coin processing unit 131 and banknote processing unit 132 of the cash processing unit 130, and performs signal input and output between these and the processor 111. The input / output interface 116 may also be further connected to a portable storage medium interface that enables writing and reading information to and from a portable storage medium.

[0035] The display input unit 120 is a touch panel display comprising a display device 121 and a touch panel 122 positioned on the display device 121. The display device 121 is, for example, an LCD (Liquid Crystal Display) and displays various screens. The touch panel 122 detects input operations to the touch panel 122 and outputs a signal to the processor 111 according to the detection result.

[0036] The cash processing unit 130 includes a coin processing unit 131 and a banknote processing unit 132. The coin processing unit 131 takes in, identifies, and counts incoming coins, and counts and discharges out incoming coins. The banknote processing unit 132 takes in, identifies, and counts incoming banknotes, and counts and discharges out outgoing banknotes. The banknote processing unit 132 also includes a banknote reading unit 132a that reads the serial number information of incoming banknotes. The serial number information read by the banknote reading unit 132a includes at least the serial number printed on the banknote and the color of the serial number. The banknote reading unit 132a can perform such readings based on image information of the banknote acquired using, for example, an image acquisition means such as an image sensor.

[0037] In the verification machine 10 illustrated in Figure 3, the storage device 115 provides, for example, the function of the storage unit 11. The banknote reading unit 132a provides, for example, the function of the reading unit 12. The processor 111 provides, for example, the functions of the verification unit 13, registration unit 14, acquisition unit 15, and discrimination unit 16.

[0038] Next, we will explain in detail the processes performed by the counterfeit banknote detection system 1.

[0039] In the counterfeit banknote detection system 1, the DB server 20 registers (stores) the serial number information of issued banknotes (including at least the serial number printed on the banknote and the color of that serial number) in the serial number master 21a of DB 21. Subsequently, if new banknotes are issued, the DB server 20 registers the serial number information of the newly issued banknotes in the serial number master 21a of DB 21. As a result, the serial number master 21a of DB 21 will contain the serial number information of all banknotes issued to date. The serial number information of issued banknotes is obtained, for example, from the Bank of Japan, which is the issuer of the banknotes.

[0040] The DB server 20 transmits the serial number information of issued banknotes registered in the serial number master 21a of DB 21 to each verification machine 10. Subsequently, if the serial number information of newly issued banknotes is registered in the serial number master 21a of DB 21, the DB server 20 transmits the serial number information of the newly issued banknotes to each verification machine 10.

[0041] When the verification machine 10 receives serial number information for issued banknotes from the DB server 20, it stores the received serial number information in the storage device 115. As a result, the storage device 115 of the verification machine 10 stores serial number information for all banknotes issued to date, just like the serial number master 21a in DB 21. Thus, the serial number information for issued banknotes stored in the storage device 115 is obtained from DB 21 (serial number master 21a).

[0042] In a business establishment equipped with a scrutiny machine 10, for example, when cash such as sales proceeds is collected from a store, the scrutiny machine 10 takes in the collected cash and scrutinizes it. At this time, the scrutiny machine 10 also detects counterfeit banknotes (determining whether the collected banknotes are counterfeit or not). The counterfeit banknote detection process (processing related to the counterfeit banknote detection function) performed by the scrutiny machine 10 at this time will be explained in detail below.

[0043] Figure 4 is a flowchart illustrating the flow of the counterfeit banknote detection process performed by the inspection machine. This counterfeit banknote detection process is performed for each collected banknote, and is carried out by the processor 111 of the inspection machine 10 executing a counterfeit banknote detection program.

[0044] When the counterfeit banknote detection process illustrated in Figure 4 is initiated, the inspection machine 10 first reads the serial number information of the collected banknote using the banknote reading unit 132a (S101).

[0045] Next, the verification machine 10 compares the serial number information of the collected banknotes read in S101 with the serial number information of the issued banknotes stored in the storage device 115 (S102). Then, based on the result of the comparison in S102, the verification machine 10 determines whether or not the same serial number information as the serial number information of the collected banknotes read in S101 is stored in the storage device 115 (S103).

[0046] If the result of the determination in S103 is Yes, the inspection machine 10 registers (stores) inspection result information, including the collection date, scheduled dispatch date, serial number information, customer name (name of the customer who requested collection), and store name (name of the store from which the banknotes were collected), for the collected banknotes whose serial number information was read in S101, in the inspection result master 21b of DB21 (S104). Specifically, this registration is performed by the inspection machine 10 sending the inspection result information to the DB server 20, and the DB server 20 registering the received inspection result information in the inspection result master 21b of DB21. Here, the collection date, customer name, and store name included in the inspection result information may be entered into the inspection machine 10 by an employee (such as an employee of the business where the inspection machine 10 is installed) based on the information on the collection slip at the time of cash collection. Furthermore, the scheduled dispatch date included in the verification result information may be determined by an employee and entered into the verification machine 10, for example, based on the collection date or the delivery date (the date on which the collected banknotes are delivered to the destination) agreed upon in the contract with the customer. In this case, the employee may, for example, determine the following Monday after the collection date as the scheduled dispatch date, or the same day as the delivery date as the scheduled dispatch date. Alternatively, the verification machine 10 may be configured to automatically determine the scheduled dispatch date by the employee. In this case, for example, when the collection date or delivery date is entered into the verification machine 10 by the employee, the verification machine 10 may automatically calculate the scheduled dispatch date based on the entered collection date or delivery date.

[0047] Next, the inspection machine 10 obtains the previous scheduled issuance date of the collected banknotes from the inspection result master 21b in DB21 (S105). Specifically, this is done by the inspection machine 10 requesting the previous scheduled issuance date of the collected banknotes from the DB server 20, and in response to this request, the DB server 20 obtains the previous scheduled issuance date of the collected banknotes from the inspection result master 21b in DB21 and transmits it to the inspection machine 10. Here, the previous scheduled issuance date of the collected banknotes is the scheduled issuance date included in the inspection result information that includes the most recent collection date among the inspection result information that includes the serial number information of the collected banknotes (excluding the inspection result information registered in S104 and the inspection result information that includes the alert flag described later) registered in the inspection result master 21b in DB21.

[0048] Next, the inspection machine 10 determines whether the collection date of the collected banknotes (which is also the collection date included in the inspection result information registered in S104) is earlier than the previous scheduled issuance date of the collected banknotes acquired in S105 (S106).

[0049] Note that in S105, it may not be possible to obtain the previous scheduled issuance date of the collected banknotes. For example, this occurs when the verification result information, including the serial number information of the collected banknotes, is registered for the first time in the verification result master 21b of DB21 in S104. In this case, since no other verification result information including the serial number information of the collected banknotes has been registered, the previous scheduled issuance date of the collected banknotes cannot be obtained. Therefore, in such cases, the process proceeds to S106 without obtaining the previous scheduled issuance date of the collected banknotes, and in the judgment of S106, the process proceeds with the judgment result set to NO.

[0050] In the determination in S106, if the determination result is YES, it means that banknotes that should still be in the vault and not yet issued have been recovered, so the inspection machine 10 identifies the recovered banknotes as counterfeit banknotes (S107). The recovered banknotes identified as counterfeit banknotes are, for example, discharged (returned) from the inspection machine 10. Then, in S104, the inspection machine 10 adds an alert flag to the inspection result information registered in the inspection result master 21b of DB21 and deletes the scheduled issuance date from the said inspection result information (S108). Specifically, this addition and deletion is performed when the inspection machine 10 requests the DB server 20 to add the alert flag and delete the scheduled issuance date, and in response to this request, the DB server 20 adds the alert flag and deletes the scheduled issuance date to the inspection result information (the inspection result information registered in S104) registered in the inspection result master 21b of DB21. Once the processing in S108 is complete, the counterfeit banknote detection process for the recovered banknotes is finished. The detailed examination results information, for which an alert flag was added in S108 and S110 (described later), will then be provided to, for example, the police.

[0051] On the other hand, if the result of S106 is NO, it is assumed that the issued banknotes have been recovered (or that the previous scheduled issuance date of the recovered banknotes could not be obtained in S105), so the recovered banknotes are not identified as counterfeit, and the counterfeit banknote detection process for those recovered banknotes ends. The recovered banknotes that are not identified as counterfeit are bundled together according to their scheduled issuance date and stored in the vault, and then released on the scheduled issuance date and promptly delivered to the recipient. The recovered banknotes that are released are delivered to the recipient, for example, as change.

[0052] Furthermore, if the result of the S103 determination is NO, it means that a banknote that should not have been issued has been collected, so the inspection machine 10 identifies the collected banknote as a counterfeit banknote (S109). The collected banknote identified as a counterfeit banknote is, for example, discharged (returned) from the inspection machine 10. The inspection machine 10 then registers the inspection result information, including the collection date, serial number information, customer name, store name, and alert flag, for the collected banknote whose serial number information was read in S101, into the inspection result master 21b of DB21 (S110). Specifically, this registration is performed by the inspection machine 10 sending the inspection result information to the DB server 20, and the DB server 20 registering the received inspection result information into the inspection result master 21b of DB21. The inspection result information registered in S110 does not include the scheduled dispatch date. When the processing in S110 is completed, the counterfeit banknote detection process for the collected banknote is completed.

[0053] A concrete example of the counterfeit banknote detection process illustrated in Figure 4 will be explained using Figure 5.

[0054] Figure 5 is an example of a master file containing registered inspection result information.

[0055] In the specific example described here, it is assumed that, before the counterfeit banknote detection process begins, the verification result master 21b has registered the verification result information for data 1 and the verification result information for data 2, as illustrated in Figure 5, as registered data. The verification result information for data 1 includes the collection date: "2024 / 06 / 26", the scheduled dispatch date: "2024 / 07 / 02", the serial number in the serial number information: "AA000000AA", the color of the serial number: "01 (black)", the customer name: "○○ customer", and the store name: "×× store", etc., but does not include an alert flag. The detailed analysis results for Data 2 include the retrieval date: "2024 / 06 / 27", the scheduled dispatch date: "2024 / 07 / 03", the serial number in the serial number information: "AA000000BB", the color of the serial number: "02 (blue)", the customer name: "□□ customer", and the store name: "△△ store", but do not include any alert flags.

[0056] Assume that the counterfeit banknote detection process is initiated, processes S101 and S102 are performed, and the result of S103 is YES. In the subsequent S104, assume that the verification result information of data 3, as exemplified in Figure 5, is registered as additional registration data in the verification result master 21b. The verification result information of data 3 includes the collection date: "2024 / 07 / 01", the scheduled dispatch date: "2024 / 07 / 07", the serial number in the serial number information: "AA000000AA", the color of the serial number: "01 (black)", the customer name: "○○ customer", and the store name: "×× store", etc.

[0057] In the subsequent S105, the scheduled dispatch date "2024 / 07 / 02" included in the scrutiny result information of Data 1 is obtained as the previous scheduled dispatch date of the collected banknotes. In this specific example, the scrutiny result information, which includes the serial number information of the collected banknotes (serial number: "AA000000AA" and serial number color: "01 (black)") registered in the scrutiny result master 21b, becomes the scrutiny result information of Data 1 and the scrutiny result information of Data 3. However, the scrutiny result information of Data 3 was registered in S104 and is therefore excluded. Since the remaining scrutiny result information of Data 1 does not contain an alert flag, the scheduled dispatch date "2024 / 07 / 02" included in the scrutiny result information of Data 1 is obtained as the previous scheduled dispatch date of the collected banknotes.

[0058] In the following step S106, it is determined whether the collection date of the collected banknotes, "2024 / 07 / 01" (which is also the collection date included in the detailed analysis results of Data 3), is earlier than the previous scheduled issuance date of the collected banknotes, "2024 / 07 / 02," which was obtained in S105.

[0059] In this case, the result of the judgment in S106 is YES, so in the following S107, the collected banknotes are identified as counterfeit. In this case, the banknotes that were scheduled to be released on "2024 / 07 / 02" and should still be in the vault were collected on "2024 / 07 / 01", so the collected banknotes are identified as counterfeit. The collected banknotes identified as counterfeit are then discharged (returned) from, for example, the verification machine 10.

[0060] Then, in the following S108, an alert flag is added to the inspection result information of data 3, which was registered in the inspection result master 21b of DB21 in S104, and the scheduled shipping date "2024 / 07 / 07" is removed from the inspection result information of data 3.

[0061] As described above, according to this embodiment, even if the serial number information of the collected banknote matches the serial number information of the issued banknote, if the collection date of the collected banknote is earlier than the previous scheduled date of the collected banknote, the collected banknote will be identified as a counterfeit banknote, thereby improving the accuracy of counterfeit banknote detection. Furthermore, even if the accuracy of banknote counterfeiting increases and it becomes difficult to detect counterfeit banknotes using optical sensors or magnetic sensors, it is still possible to detect counterfeit banknotes.

[0062] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various improvements and modifications are possible without departing from the spirit of the invention. [Explanation of Symbols]
