Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ticket processing system that detects forgery or alteration of voting tickets in a system for issuing and refunding voting tickets in various prediction games.

With the development of electronic computers and the increase in refund operations based on voting results in various games, etc., devices were developed that instantly created and issued desired voting tickets to voters and refunded winning tickets. Alternatively, it is used in auto racing, etc.

In such a device, there is a strong demand for a means to eliminate fraudulent acts caused by counterfeit or altered tickets when paying out winning tickets.

[Problems to be solved by conventional technology and invention]

As a conventional forgery/alteration detection method in this type of ticket processing system, for example, when the ticket number assigned to each issued ticket is calculated according to predetermined rules, it becomes a fixed number (so-called secret number). Although measures have been taken to prevent forgery and alteration of ticket numbers by providing such characteristics, once the calculation rules and secret numbers mentioned above are leaked, forgery and alteration of ticket numbers becomes possible.

In addition, a method to prevent counterfeiting of tickets by printing part or all of a predetermined pattern recorded on paper using magnetic ink and verifying the part printed with magnetic ink at the time of refund is also considered. However, with advanced counterfeiting and alteration printing technology, it has become possible to forge or alter patterns using magnetic ink, and there is a fear that sufficient prevention effects may not be achieved.

Therefore, the purpose of the present invention is not to detect forgery or alteration based on information that is printed on the face of a note, but also to prevent forgery or alteration without requiring any extra processing on the face of the note. Our aim is to provide the technology to

[Means for solving problems]

In order to solve these problems, the present invention focuses on the fact that voting tickets used for horse racing, etc. have a background pattern attached to them, and that the background pattern can be placed in a different position for each ticket. The idea is to create a cryptographic code using .

According to the present invention, such a ticket processing system capable of detecting forgery/alteration records issuing data on a ticket with a background pattern printed on it, creates an encryption code from information read from the background pattern and the issue data, and processes the encryption code by recording the issuing data on the ticket with the background pattern printed thereon. After recording,
A ticketing device that issues a ticket when the created cryptographic code and the recorded cryptographic code match, and a ticket issuing device that creates a cryptographic code from the ground pattern of the issued ticket and issuing data, and records the created cryptographic code and the ticket face. This is achieved by comprising a receiving device that determines whether the ticket is valid or not by checking the read information of the encrypted code contained in the ticket.

[Effect]

The background pattern that is pre-printed on the paper is repeated at a period (interval) that is different from the dimensions of the ticket, so
The position of the background pattern on each ticket varies.

The present invention focuses on this point, and synthesizes the mutual relationship between the issuance data and the background pattern recorded on the ticket (for example, the intersection coordinate values), as well as the contents of the issuance data (for example, the four arithmetic operations between the intersection coordinate values and the issuance data). A code is created and recorded on the ticket, and a ticket is issued only when the coded data created for confirmation and the recorded coded data match, and the authenticity of the ticket is determined by the coded data based on the background pattern on the ticket and the issuing data. This is done by creating a paper and comparing this data with the encrypted data recorded on the face of the ticket, thereby detecting unauthorized use of the paper or unauthorized changes to the recorded contents of the recorded ticket. This is possible without the need for extra processing.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a ticket issuing device according to an embodiment of the present invention, FIG. 2 is a diagram showing a receiving device according to an embodiment of the present invention, and FIG. 3 is a diagram showing an example of paper in FIG. 1. FIG. 4 is a diagram showing an example of the feature extraction method in FIG. 1.

1 to 4, when a voting ticket is created by the ticket issuing device 31, an unrecorded paper 101 as shown in FIG.
The image is sent to the printing section 35 by the printer.

As shown in FIG. 3, a waveform background pattern 103 is printed on the voting ticket 101 in advance. Since the interval between the tint blocks 103 is determined to be different from the dimension d of the voting ticket, the printing position of the tint block varies for each paper 101.

The printing unit 35 prints required issuance data in the area 102 on the voting ticket 101 that has been sent. Note that the color of the printed issue data and the color of the background pattern are determined to be different.

The voting ticket 101 on which the issuance data has been printed is further sent to the reading sections 32 and 33 by the paper transport section 106.

The reading unit 32 includes light receiving elements 2 and 3 arranged vertically and horizontally as shown in FIG. The background pattern 103 recorded in the area 1 corresponding to one character of the issue data as shown in FIG. The value is transmitted to the encryption code generation section 34.

On the other hand, the reading section 33 has a configuration as shown in FIG. The read and coordinate values are transmitted to the encryption code creation section 34.

The cryptographic code creation unit 34 determines the mutual relationship between the coordinate values of the ground pattern 103 transmitted from the reading unit 32 and the recorded characters 105 transmitted from the reading unit 33, for example, the ground pattern 103 and the recorded characters 105 as shown in FIG. 4b. A predetermined calculation process (for example, addition) is performed between the coordinate values of the intersection point P and the recorded characters 105 to create an encryption code. The above processing is executed for each recorded character in the issue data recording area 102, and the final encryption code is transmitted to the printing unit 35.

On the other hand, the paper 101 is sent to the printing unit 35 again by the paper transport unit 106.

The printing unit 35 records the encryption code transmitted from the encryption code creation unit 34 in the area 11 of the paper 101 that has arrived again.

The paper 101 on which the encryption code has been recorded is sent to the reading units 32 and 33 again.

The reading unit 32 reads out the coordinate values of only the tint block 103 from each area 1 and transmits them to the encryption code creation unit 34, as described above, and the reading unit 33 also
The coordinate values of only the recorded characters 105 are read from each area 1 and transmitted to the encryption code generation section 34, and the encryption code is further read from the area 11, and the collation section 36
to communicate.

The cryptographic code creation unit 34 creates a cryptographic code based on the coordinate values and the like transmitted from the reading units 32 and 33 in the same process as described above, and transmits it to the verification unit 36.

The collation unit 36 collates the cipher code transmitted from the reading unit 33 and the cipher code transmitted from the cipher code generation unit 34, and when it is confirmed that the two match, it outputs a match signal, and also outputs a match signal when the two match. If they do not match, a mismatch signal is output and transmitted to the determining section 37, respectively.

When the matching signal is transmitted from the matching unit 36, the determining unit 37 issues the paper 101 sent by the paper transporting unit 106 as a regular voting ticket 101' (path 38), and also issues a mismatch signal from the matching unit 36. If the signal is transmitted, the paper 101 is discarded (route 39).

If the voting ticket 101' issued through the above process is successful and submitted to the refund office, it is input to the receiving device 61 and sent to the reading units 62 and 63 by the paper transport unit 107.

The reading unit 62 is the reading unit 3 in the ticket issuing device 31.
Area 1 on the voting ticket 101'
It reads only the background pattern 103 recorded therein and transmits the coordinate values to the cryptographic code generation section 64.

On the other hand, the reading section 63 has the same configuration as the reading section 33, reads only the recorded characters 105 recorded in the area 1, transmits the coordinate values to the encryption code generation section 64, and also reads the encryption code from the area 11. It is read and transmitted to the verification unit 66.

The cryptographic code creation unit 64 uses the same process as the cryptographic code creation unit 34 in the ticket issuing device 31 to calculate the coordinate values of the background pattern 103 transmitted from the reading unit 62 and the coordinate values of the recorded characters 105 transmitted from the reading unit 63. The codes are combined to create an encryption code and transmitted to the collation unit 66.

The collation unit 66 collates the cipher code transmitted from the reading unit 63 and the cipher code transmitted from the cipher code creation unit 64, and when it is confirmed that the two match, it outputs a matching signal, and also outputs a match signal when the two match. If they do not match, a mismatch signal is output and transmitted to the determining section 67, respectively.

The determining section 67 outputs a detection signal 68 indicating that the voting ticket 101' is genuine when a matching signal is transmitted from the collating section 66, and outputs a detection signal 68 indicating that the voting ticket 101' is genuine, and when a mismatching signal is transmitted from the collating section 66. voting ticket 10
A detection signal 69 indicating that 1' is not normal is output.

As is clear from the above description, according to the present embodiment, the ticket issuing device 31 generates an encrypted code created from reading information of the background pattern 103 printed on the paper 101 and issuance data printed on the paper 101 on the voting ticket 101.
1', and the receiving device 61 prints the winning voting ticket 1.
The encryption code created in the same process as the ticket issuing device 31 from the reading information of the background pattern 103 of 01' and the issuing data is compared with the encryption code read from the voting ticket 101' to determine whether the voting ticket 101' is correct or not. The background pattern 103 is different for each voting ticket as mentioned above, so the background pattern 103 is different for each voting ticket.
It becomes difficult to decipher the encryption process from the encryption code including the read information of 03, and it becomes extremely difficult to forge or alter the voting ticket.

It should be noted that the above is just one embodiment of the present invention, and for example, the shape of the background pattern 103 printed on the paper 101, the recording area 10 of the issuing data, the encryption code, etc.
1, 11, etc. are not limited to those shown in the drawings, and many other modifications may be considered, but the effects of the present invention remain the same in any case. Furthermore, the encryption code is not limited to one created by adding the coordinates of the intersection point P between the tint block 103 and the recorded character 105 and the recorded character 105; 103 slope) and
Composition with recorded characters 105 through various arithmetic operations, etc.
Although many other modifications may be considered, the effects of the present invention remain the same in any case.

〔Effect of the invention〕

As described above, according to the present invention, in the ticket processing system, it becomes difficult to decipher the encryption process from the encryption code, and it becomes possible to detect unauthorized use of paper or unauthorized alteration of recorded contents of recorded tickets.
