Description

Paper classification system and paper classification method

technical field

The present invention relates to a paper discriminating system and a paper discriminating method, and is applicable to the paper discriminating system and paper discriminating method for discriminating the authenticity of paper.

Background technique

Conventionally, there is known a sheet discriminating device that discriminates the authenticity of a sheet based on the characteristics of the sheet. In the sheet discriminating device, the maximum value and the minimum value of the feature quantity for discriminating authenticity are set in advance, and the range from the maximum value to the minimum value is set as a reference threshold value. And, when the characteristic amount of the paper sheet is within the range of the threshold value, the paper sheet is judged as genuine, and when the characteristic amount of the paper sheet is outside the range of the threshold value, the paper sheet is judged as fake. coupon.

In such a method of judging the authenticity of paper sheets, it is necessary to take into account unevenness in printing and paper quality of paper sheets, and therefore it is necessary to set the threshold value of the feature value to have a certain range. As a result, there is a problem that the possibility of misidentifying a counterfeit bill or a defective bill as a genuine bill becomes high.

Therefore, in order to solve the above-mentioned problems, a technology has been disclosed that uses unique information such as serial numbers of paper sheets, and determines threshold values based on feature quantities stored for each unique information, thereby enabling high-precision discrimination (for example, Patent Document 1 ).

Moreover, the technique which returns the banknote discriminated as a counterfeit bill by the above-mentioned method to a user, or collects it in the collection box in an apparatus is disclosed. At this time, try to minimize the loss of counterfeit bills by properly handling the papers judged as counterfeit bills, and obtain and save information about the counterfeit bills (images of paper, printed information, or information used to identify users). information, etc.) (for example, Patent Document 2).

Patent Document 1: Japanese Patent Laid-Open No. 2012-14529

Patent Document 2: International Publication of U.S. Patent No. 2004/019287

However, in Patent Document 1, when a paper sheet having the same unique information as the stored unique information is read, authenticity can be discriminated with high accuracy, but for counterfeiting by changing the serial number There is a problem that high-precision discrimination cannot be performed unless all the characteristic information of each of the unique information is stored.

In addition, in Patent Document 2, information on paper sheets discriminated as counterfeit bills is stored. Although this information is paper-specific information such as paper images and serial numbers, it cannot be said to be paper-specific information. Therefore, there is a problem that although the stored unique information can be used for processing the counterfeit bill, it cannot be used for discriminating counterfeit bills having the same characteristic information.

Contents of the invention

The present invention was made in consideration of the above problems, and proposes a paper identification system and a paper identification method in which the characteristic information of a paper that is discriminated as a counterfeit bill based on the unique information and characteristic information of the paper can be used to discriminate other papers .

In order to solve this problem, the present invention provides a sheet discriminating system comprising a sheet processing device for processing one or more sheets, and a host computer connected to the sheet processing device, wherein: The paper sheet processing apparatus reads characteristic information of the paper sheet, and the paper sheet characteristic information includes unique information for identifying the paper sheet and feature quantities indicating various states of the paper sheet; the host computer includes: a storage unit , storing the inherent information of the above-mentioned paper sheets read by the above-mentioned paper sheet processing device in association with the feature quantity; and the control part, based on the feature information of the above-mentioned paper sheets, distinguishes the authenticity of each paper sheet; the above-mentioned control part will judge as The characteristic information of the paper sheet of the counterfeit bill is stored in the storage unit as counterfeit bill information.

According to this configuration, the unique information for identifying each paper sheet and the feature quantities indicating various states of the banknote are read by the paper sheet processing apparatus and sent to the host computer. Then, the host computer judges the authenticity of the paper sheet based on the transmitted unique information and feature value, and stores information on the paper sheet when it is judged that the paper sheet is a counterfeit bill. In this way, the stored information on counterfeit bills can be used to discriminate other papers, and the authenticity of papers can be more appropriately discriminated.

Invention effect

According to the present invention, the authenticity of paper sheets can be appropriately judged by using characteristic information of paper sheets discriminated as counterfeit bills based on paper specific information and characteristic information for discriminating other paper sheets.

(1-2) Paper discrimination processing

(1-2-1) ATM deposit transaction processing

Next, the operation of the deposit transaction of this embodiment will be described. FIG. 6 is a flowchart showing deposit transaction processing in ATM200. The control part 201 of ATM200 displays various transactions on the display screen of the operation part 203, and waits until a deposit transaction is selected by a user via an input part. And, when any transaction on the display screen is selected by the user, the control unit 201 determines whether or not the deposit transaction is selected ( S100 ).

When deposit transaction is selected in step S100 , it is determined whether or not a banknote has been inserted from the transport unit 204 ( S101 ). In step S101 , it is determined whether or not there is a banknote in the banknote insertion opening by a sensor for checking whether there is a banknote loaded in the insertion opening of the transport unit 204 . In addition, in step S101, it may be detected by the above-mentioned sensor whether a banknote has been inserted, or the user may input input completion from the input unit, or it may be determined that a banknote has been inserted when the timer elapses a predetermined time.

When it is determined in step S101 that a banknote has been inserted, that is, there is a banknote in the banknote insertion slot, the banknote is conveyed to the reading unit 205 ( S102 ). In step S102, a motor, a conveyance roller, etc. are driven, and the banknote inserted into the banknote insertion opening is conveyed to the reading part 205. FIG. In addition, when a plurality of banknotes are inserted, they are sequentially conveyed to the reading unit 205 one by one, and the conveyance process is repeated until all conveyance is completed. The processing of step S102 may be performed in parallel with the reading processing of step S103 described later.

And the control part 201 judges whether the information of the banknote conveyed to the reading part 205 was read (S103). Specifically, the control unit 201 determines whether or not the image of the banknote has been acquired. As the reading process of banknote information in step S103, the image of a banknote acquired by image scanning, etc. are mentioned, for example.

When the banknote information cannot be read in step S103, the banknote is conveyed to the banknote extraction port (S110), and the banknote is returned to the user.

On the other hand, when banknote information is acquired in step S103, it is judged whether the feature quantity of a banknote was calculated (S104). Specifically, the control unit 201 calculates a serial number and a feature value based on the banknote information read by the reading unit 205 . Even if the banknote information is read in step S103, when the condition of the banknote is not good, for example, the banknote is severely damaged and cannot be read, or it is paper other than acceptable banknotes, sometimes The characteristic quantity of the banknote cannot be calculated.

In step S104, when the characteristic quantity of a banknote was not calculated, a banknote is conveyed to a banknote extraction port (S110), and a banknote is returned to a user.

On the other hand, when the feature value of the banknote is calculated in step S104, the control unit 201 stores the banknote information read in step S103 and the serial number and feature value calculated in step S104 in the storage unit 202. middle. Then, the serial number and the characteristic amount calculated in step S104 are transmitted to the host computer 300 (S105). Specifically, the serial numbers and feature quantities of banknotes stored in the storage unit 202 are transmitted from the communication unit 206 to the host computer 300 via 101 . The authenticity judgment process of the banknote by the host computer 300 will be described in detail later.

Then, the control unit 201 judges whether or not a judgment result has been received from the host computer 300 ( S106 ). When it is determined in step S106 that the discrimination result has been received from the host computer 300 , it is determined whether or not the banknote has been discriminated as a genuine bill based on the received discrimination result ( S107 ).

When it is determined in step S107 that the banknotes are determined to be authentic, the control unit 201 transports the banknotes to the banknote storage, and ends the deposit transaction. On the other hand, when it is judged in step S107 that a banknote is discriminated as a counterfeit bill, the said banknote is conveyed to the banknote recovery storage, and deposit transaction is complete|finished.

(1-2-2) Deposit transaction processing of the host computer

In step S105 of FIG. 6, the host computer 300 receives the serial number and characteristic quantity of the banknote transmitted from ATM200. Here, deposit transaction processing performed by the host computer 300 will be described with reference to FIG. 7 . FIG. 7 is a flowchart showing deposit transaction processing of the host computer 300 . As shown in FIG. 7, the host computer 300 waits until the serial number and characteristic quantity of a banknote are received from ATM200 (S200).

When it is determined in step S200 that the serial number and the characteristic amount of the banknote have been received, the control unit 302 determines whether information corresponding to the banknote received in step S200 has been registered in the database (S201). Specifically, the control unit 302 determines whether or not the same serial number as the serial number of the banknote received in step S200 is registered in the banknote information database 400 stored in the storage unit 303 .

When it is determined in step S201 that the same serial number as that of the banknote is registered, the process of step S203 is executed. On the other hand, when it judges in step S201 that the same serial number as the serial number of a banknote is not registered, the process of step S202 is performed.

In step S202, the control part 302 calculates the threshold value for authenticity determination of a banknote based on the feature quantity corresponding to the serial number of the banknote registered in the banknote information database 400. For example, in the banknote information database 400 shown in FIG. 2, when the received serial number is "AAA111", first, a threshold value is calculated based on the feature quantity "a1" registered as a feature quantity. For example, the threshold is composed of a maximum value and a minimum value, and is calculated referring to a maximum value “Amax” and a minimum value “Amin” that are set in advance in the feature value threshold table 500 as references of feature values. Specifically, as shown in FIG. 5 , based on the feature value "a1", the maximum value "Amax'" is calculated such that the range "α'" is smaller than the range "α" between the maximum value "Amax" and the minimum value "Amin". and minimum value "Amin'".

The maximum value "Amax'" and the minimum value "Amin'" calculated as described above are set as the allowable range of the banknote with the serial number "AAA111" that should be judged to be authentic with respect to the feature value A. In addition, other threshold values, such as feature quantity B and feature quantity C, are calculated similarly to feature quantity A from the feature quantity associated with each banknote. In step S202 , the control unit 302 sets the calculated threshold value of the feature amount in the feature amount threshold table 500 as a threshold for discrimination.

In addition, in step S203, the control unit 302 performs authenticity discrimination of the banknote based on the threshold value calculated for authenticity determination in step S203 and the feature value of the banknote received in step S200 to determine whether the banknote is genuine or not. Counterfeit coupons. The control unit 302 judges whether or not the bill is a counterfeit bill based on the serial number and feature value stored in the counterfeit bill information database 600 stored in the storage unit 303 . In addition, even when there is a change in feature value due to age, fold, damage, etc., by comprehensively judging a plurality of feature values, it is judged whether or not it is a counterfeit bill, thereby enabling more appropriate counterfeit bill judgment.

And the control part 302 transmits the discrimination result of the authenticity of the banknote performed in step S203 to ATM200 (S204).

Next, in step S203, it is judged whether the result of discrimination of the authenticity of a banknote is a genuine note (S205). When it is judged in step S205 that the authenticity discrimination result of the banknote is genuine, the control unit 302 registers the banknote information in the banknote information database 400 (S206). Specifically, when the banknote information of the same serial number as the received serial number is already registered in the banknote information database 400, the control part 302 overwrites the registered feature quantity with the feature quantity transmitted from ATM200.

For example, when the banknote information database 400 is stored in the storage unit 303, if the received serial number is "AAA111" and the received feature value A is "a1'", it will be registered as a feature "a1" of the quantity A is rewritten as "a1'". In addition, other feature quantities such as the feature quantity B are similarly rewritten to the received feature quantities. On the other hand, when the same banknote information as the received serial number is not registered in the banknote information database 400 , a new serial number and feature quantity are registered in the banknote information database 400 .

Then, when it is determined in step S205 that the authenticity of the banknote is counterfeit, the control unit 302 registers the serial number and feature value of the banknote determined to be counterfeit in the counterfeit information database 600 (S207).

In this embodiment, various embodiments other than the above-mentioned modes can be adopted. For example, in the above-mentioned embodiment, the present invention was applied to the banknote handling system 100 and described, but the present invention is not limited to this example, and the present invention can also be applied to a paper handling system that handles other paper such as securities. .

In addition, in the above-mentioned embodiment, the case where the authenticity judgment to which this embodiment is applied is performed at the time of deposit transaction is described, but it is not limited to this example, and the authenticity judgment to which this embodiment is applied may be performed at the time of money-out transaction. Discrimination processing.

In addition, in the said embodiment, the case where the banknote information database 400 was saved in the storage part 303 of the host computer 300 was demonstrated, but it is not limited to this example, You may store the banknote information database 400 in the storage part 202 of ATM200 . In addition, you may store the banknote information database 400 in two devices of the host computer 300 and ATM200.

In addition, in above-mentioned embodiment, described the situation that preserves counterfeit bill information database 600 in the storage unit 303 of host computer 300, but not limited to this example, also can preserve counterfeit bill information database 600 in the storage unit of ATM200 202 in.

When a counterfeit bill registration instruction is received from the host computer 300 in step S300 , it is determined whether information of the received counterfeit bill is registered in the banknote information database 400 ( S301 ).

When it is determined in step S301 that the counterfeit bill information received in step S300 is registered in the banknote information database 400, the banknote information is registered in the counterfeit bill information database 600, and the counterfeit bill information registration process ends.

On the other hand, when it is determined in step S301 that the counterfeit bill information received in step S300 is not registered in the banknote information database 400 , the counterfeit bill information registration process is terminated ( S302 ).

(2-2-2) ATM withdrawal transaction processing

Next, the operation of the payment transaction of this embodiment will be described. FIG. 9 is a flowchart showing details of the payment transaction processing of ATM200. ATM200 displays various transactions on the display screen of the operation part 203, and waits until a user selects a payment transaction via an input part. Then, when any transaction on the display screen is selected by the user, the control unit 201 determines whether or not a payment transaction is selected ( S400 ).

When the payment transaction is selected in step S400, it waits until the user inputs the payment amount through the display screen. And when it is judged in step S401 that the user has input the payment amount, the control part 201 conveys a banknote to the reading part 205 (S402). Specifically, the control unit 201 sends out the banknotes from the banknote storage, drives the motor and the conveyance path, and conveys the banknotes to the reading unit 205 . Moreover, when there are many banknotes sent out from a banknote storage, it conveys to the reading part 205 one by one sequentially, and repeats conveyance processing until all conveyance is completed. The processing of step S402 may be performed in parallel with the reading processing of step S403 described later.

When a banknote is conveyed to the reading part 205 in step S402, the control part 201 determines whether the banknote information of the conveyed banknote was read (S403).

When it is determined in step S403 that the banknote information has been read, the control unit 201 determines whether or not the feature amount of the banknote has been calculated ( S404 ).

On the other hand, when the banknote information cannot be read in step S403, the control part 201 conveys a banknote to a banknote collection box (S408), sends out a next banknote from a banknote storage, and repeats the process after step S402.

In step S404 , the control unit 201 calculates a serial number and a feature amount based on the banknote information read by the reading unit 205 . And the control part 201 memorize|stores the banknote information read in step S403, the serial number calculated in step S404, and characteristic information in the storage part 202.

On the other hand, when it is determined in step S404 that the feature value of the banknote cannot be calculated, the control unit 201 transports the banknote to the banknote collection box (S408), delivers the next banknote from the banknote storage, and repeats the processes after step S402.

Furthermore, the control unit 201 discriminates the banknotes based on the feature value thresholds of the feature value threshold table 500 shown in FIG. Is it a real coupon or a counterfeit coupon (S405).

And when it is judged in step S405 that a banknote is judged as a genuine bill, the control part 201 conveys this banknote to a banknote take-out port (S407), makes it take out by a user, and ends a payment transaction.

On the other hand, when it is determined in step S405 that the banknote is discriminated as a counterfeit bill, the banknote is transported to the banknote collection box ( S408 ), the next banknote is sent out from the banknote storage box, and the processes after step S402 are repeated.

(2-3) Effects of the present embodiment

Thus, by storing the banknote information database 400, the characteristic value threshold value table 500, and the counterfeit bill information database 600 in the storage part 202 of ATM200, frequent communication process with the host computer 300 is abolished, and processing speed can be improved. Furthermore, by notifying the counterfeit bill information from the host computer 300 in advance, even a banknote without a serial number stored in the banknote information database 400 can discriminate the authenticity of the banknote and perform more accurate discrimination processing.
