Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention detects abnormal voting due to fraud in a totalizer system that sells and refunds voting tickets in gambling competitions such as horse racing and bicycle racing. This invention relates to a method for detecting abnormal votes in a totalizer system.

[Technology background, conventional technology and problems]

In gambling competitions, a totalizer system (voting ticket counting system) using a computer system is used for the convenience of voters (fans).

In such a totalizer system, a voting ticket vending machine,
It consists of a voting ticket refund machine and a computer-based tallying system. Voting information from voting tickets sold by the voting ticket vending machine is sent to the computer, stored in a tally file, and used for tallying the voting information. It is also used to calculate the amount of money expected to be paid, and is displayed on a display board called Otsuzu, which helps fans decide on their votes. On the other hand, the winning voting ticket is read by the refund machine and sent to the computer, the voting information is checked, and if it is determined to be a winning voting ticket, the refund amount is sent from the computer to the refunder and displayed. , and receive the refund on the vote. Fraud is not tolerated in gambling competitions like this.For example, if a winning ticket is counterfeited, a
Secret codes, etc. are recorded and checked, and information on the face of the card is double-checked in order to expose such fraud. Other frauds of this type include certain voters (fans) colluding with certain athletes and jockeys (trainers, horses, etc.) to conduct fraudulent races and obtain unfair refunds. There is something called a 100-cho race. That is.

They conduct races that outwit the predictions of ordinary good gambling fans, intentionally make the most popular or second most popular bets lose, and only those gamblers purchase unfair winning tickets (this is considered abnormal). vote) and get a large refund.

If such fraudulent races occur, the fairness and cleanliness of gambling competitions cannot be maintained, so efforts are being made to discover such races and expose those involved.

However, the discovery of such races and people involved has traditionally been made by experts comparing the number of votes counted at each polling station with general expected trends, and making inferences based on the lifestyles, social relationships, race history, etc. of the two racers who answered their own questions. Although we are taking precautions, this is entirely due to human intervention.

There was a problem in that the effectiveness of the training was not improved after nine months.

[Purpose of the invention]

shall be followed by you.

a. Vote tabulation processing First, prior to the start of each race, voters (voting ticket purchasers)
tells the operator the voting number and number of votes at the voting counter, and the operator inputs the input device 10 of the voting ticket vending machine 1.
The voting number and the number of votes are inputted as voting information from the input terminal 2 and displayed on the second display device 11 on the monitor. At the same time, a send key (not shown) is pressed to edit the upper sentence consisting of the terminal number and voting information, and send the upper two sentences from the first communication control device 13 to the computer 3. The computer 3 checks the sent top stain text, checks whether the voting number in question exists for that race, and if it exists, it updates the existing voting number in the tally file 31 for each race. The number of votes for the upper stain pattern is added to the number of votes, the total file 31 for each race is updated, and the total process is performed. Along with this, the computer 3 has a summary table file 3 for each terminal.
The number of prohibited votes of the upper p message is added to the existing number of votes of the voting number corresponding to the terminal number indicated in the up message of No. 2, the tally table file 32 for each terminal is updated, and the tally process is performed.

Upon completion of this tabulation process, the computer 3 edits the lower part message consisting of the event date 1 sales office code, terminal number, and serial number, sends the downstream message to the voting ticket vending machine 1, and permits the issuance of 1 ticket.

The serial number 1 is a consecutive number of voting tickets issued by the voting ticket vending machine.

This downstream message is received by the communication control device 13 of the voting ticket vending machine 1, 1 confirms ticket issuance permission, and the 1 ticket issuing device 12 receives the event date, terminal number 9 serial number, and voting number inputted in the input device 10 in the downstream message. A voting ticket TK is issued by recording the number of votes and race number on the ticket.

The issued voting ticket TK is handed over from the operator to the voter in exchange for the voting amount. In this manner, each voter casts a vote, and the computer 3 performs vote tally and ticket issuing processing to issue voting tickets TK one after another. Using this summary table file 31 for each race, the expected payout amount for each time point may be calculated before the start of the race, and may be displayed in oz.

h. Refund processing When the race is finished and the race ranking is determined, the computer 3 calculates the refund amount for the correct voting number using the summary table file 31 for each race, and stores it in the refund total loan file 34.

On the other hand, once the race is over, the voters who have cast their winning votes head to the refund counter with their winning voting tickets (tickets). The voter hands the winning voting ticket TK to the operator at the refund counter. The operator causes the reading device 2o of the voting ticket refund machine 2 to read the voting information (card surface information) on the magnetic stripe and surface characters of the voting ticket TK. The communication control device 22 transmits this voting information to the computer 3 as a message.

The computer 3 checks whether or not the ticket is a winning ticket based on the voting information such as the date of the event, the race number, and the voting number. If it is determined that the voting ticket is a winning ticket, the determination bit position corresponding to the serial number included in the upstream message of the refunded serial number record file 33 is checked in the ninth step, and it is determined whether the flag is set (refunded) or not. Check. If the flag is raised, there is a suspicion that the ticket is a counterfeit ticket, and the refund is stopped. If the flag is not raised on either side, the computer 3 flags it.

Furthermore, the refund amount for the hit vote is read out from the refund statement file 34 and transmitted to the refund machine 2 as a message. The communication control device 22 of the refund machine 2 receives this, confirms refund permission, and causes the display device 21 to display the refund amount in the bottom stain. Upon seeing this, the operator hands cash equivalent to the refund amount to the voter and completes the refund.

C2 Abnormal Voting Detection Process Next, the abnormal vote detection process according to the present invention will be explained using the processing flowcharts shown in FIGS. 3 and 8.

After the refund window closes for the last race of the day.

Look for the first hole lace. A hole race is a race in which one player is the favorite and his opponent loses, resulting in a large payout. The computer 3 reads the payout amount for each race from the payout statement file 34, and determines a race with a payout amount of a predetermined amount or more as a hole race. If there is no hole race, the process ends without performing the following processing.

Next, the computer 3 extracts the number of winning votes (or number of tickets) for each terminal (vending machine) of the hole race (for example, 3 races) from the tally table file 32 for each terminal.

The sales ratio of the number of correct votes for each terminal is calculated by dividing by the total number of correct votes in the tally table file 31 for each race, and a terminal with this sales ratio of α (for example, 1.0)% or more is searched. That is, it is checked whether winning tickets are issued concentratedly at a certain terminal (vending machine). In general, in the case of a 100-chog race, a specific few people purchase a large number of winning voting tickets, so there is a tendency for winning voting tickets to be purchased in large quantities at one or two places at once. Here, we check whether they are concentrated locally. If there are no terminals that have issued α% or more, it is determined that there is no abnormal vote and the process ends.

In the above step, the terminal period issued by a% or more (for example, 000
0") is found, the computer 3 next checks whether winning voting tickets were issued at the relevant terminal in a concentrated manner over time.

The payout determination bit group (payout bit string) of the terminal "nooo" in the hole race in question in the payout serial number record file 33 is read and checked. That is, in the judgment bit group, a flag is set for those that have already been paid out (that is, those that hit the mark).

If this continuity is greater than or equal to a predetermined number, it means that winning voting tickets have been issued consecutively for G time periods, and from this it can be detected whether winning voting tickets have been issued in a concentrated manner over time. There is. In order to easily perform this continuity check, in this embodiment, the payout bit string is divided into one section of 8 bits each, and the number of flags is counted for every 9 sections. For example, serial number 0-7
．． Divide into sections such as 8-15 degrees, 16-23 degrees, and 24-31 degrees.

The number of successful voting tickets in that section is counted by the number of flags. Then, add up the count values for each section starting from the largest value, and when the total number of winning (hit) tickets exceeds 6% (for example, 30%), calculate the number of sections added, and add 1 to the number of sections. It is determined whether the number of sections is less than C% (for example, 5%), and if it is less than 0%, it is determined that the time is concentrated. Therefore, the computer 3 considers that the winning betting tickets for the hole race were issued to specific terminals in a temporally concentrated manner, and determines that the voting is abnormal.

When an abnormal vote is detected in this manner, a player requiring attention is registered to provide material for later decisions by concerned parties. That is, the computer 3 sorts the summary table of the hole race from the summary table file 31 for each race, and selects the popular athlete (
The voting numbers of the favorite player) and the second most popular player (opposing player) are detected, the losing voting number is selected from the winning (hit) voting numbers of the hole race, and the selected voting number is selected from the race registration table file 31. Extract the information of the numbered player. Further, the computer 3 registers the information of these players in the caution player registration file 35, and if registered, increments the count value. This count value is then compared with a predetermined value (for example, 3), and if the count value is greater than or equal to the predetermined value, it is displayed on a console display (not shown) to issue a warning. The date and winning player will also be recorded during the aforementioned registration.

The contents of these caution player registration files 35 are as follows.

Provided as materials for judgment by experts and those involved in the 100-cho race, 1
Data older than one year will be automatically deleted. The reason why a count value is provided in this way is that it is considered suspicious for those involved in the Hetocho race if the favorite loses in the hole race and his opponent loses in the hole race many times.

In the above explanation, the fact that winning voting tickets were issued in a concentrated manner on a specific terminal machine is detected based on the contents of the tally table file 32 for each terminal created at the time of issuing one ticket. The issuing terminal number of the medium voting ticket will be sent to the refund machine 2.

At the time of refund, the number of votes of winning voting tickets for each terminal is counted in file 32.
The above-mentioned centralized issuance may be detected based on the contents of this total file 32.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the spirit of the present invention, and these are not excluded from the scope of the present invention.

〔Effect of the invention〕

As explained above, according to the present invention, a winning voting ticket is issued based on the voting information sent from the voting ticket vending machine to the voting information processing device or the ticket face information sent from the voting ticket refunding machine to the voting information processing device. Determine whether voting ticket vending machines are concentrated in the voting ticket vending machines, and determine from the ticket face information whether the issuance of winning voting tickets from the voting ticket vending machines determined to be concentrated is concentrated in a predetermined time period. However, since the issuance of winning voting tickets is concentrated in a predetermined time period at a predetermined voting ticket vending machine, it detects abnormal votes, so such abnormal votes can be automatically detected by data processing. This has the effect of being able to detect illegal races, contributing to the discovery of fraudulent races, etc., and helping to maintain the fairness of this type of gambling competition. Furthermore, abnormal voting is detected using information already used in the totalizer system.

It would be effective if detection could be performed without placing a burden on voters or operators and without informing them, and it is easy to realize and can be realized without causing any animosity to voters or the like.
