Field of the Invention The present invention relates to a system for preventing unauthorized use of a pachinko machine, a method for preventing unauthorized use, or a pachinko machine itself, and more particularly, to a central processing unit (CPU) of a pachinko machine, read-only. Memory (RO
M), which relates to a system for preventing unauthorized use of a pachinko machine, a method for preventing unauthorized use of a pachinko machine, and a pachinko machine for preventing unauthorized use, which early discovers unauthorized use due to unauthorized replacement of components such as control boards.

[0002]

2. Description of the Related Art A conventional pachinko machine has a central processing unit (C).
The components such as the PU, the read-only memory (ROM), and the control board have component numbers determined from their own numbering systems. Here, the “unique numbering system” means, for example, that the central processing unit (CPU) is assigned a number consisting of a unique symbol and a serial number as the central processing unit (CPU), such as a pachinko machine or other parts. It is a numbering system that is attached regardless of.

[0003] Here, the structure of the pachinko machine will be briefly described so that the problems to be solved by the present invention described later can be easily understood.

As shown in FIG. 5, a pachinko machine 20 is fixed to a fixed frame 21 in a pachinko parlor.
Usually, a pachinko ball changing device 22 is disposed on the left side. A game panel 23 is disposed in front of the pachinko machine, and a pachinko ball tray 24 and a lower plate 2 are provided below the game panel 23.
5 are provided. In addition, a handle 26 for adjusting the strength of pachinko ball punching is provided at the lower right of the pachinko ball tray 24 at the right hand of the user.

In this pachinko machine, when a pachinko ball enters a predetermined hole of the game panel 23, a liquid crystal panel on the front displays a rotating screen like a throttle machine, and when the same screen is aligned, a large number of pachinko machines are displayed at once. It has a mechanism to make a ball come out.

The pachinko machine has hinges 27, 2 provided on the upper and lower sides on the left side thereof in case of a ball jam or the like.
It rotates around 7 'to allow access to the back of the pachinko machine. Of course, in order to open the pachinko machine, the key 28 provided on the right side of the pachinko machine is released and then opened.

When the pachinko machine is opened, a back surface of the main body of the pachinko machine appears, on which a control board 29 for controlling the pachinko machine is mounted. The control board 29 includes a central processing unit (CPU) for performing processing for control.
And a read-only memory (ROM).
The central processing unit (CPU) controls various operations such as screen display of the game panel 23 and blinking of light when a pachinko ball enters a predetermined hole. The read-only memory (ROM) stores various programs for the central processing unit (CPU) to perform control.

In the program of the read-only memory (ROM), as described above, the probability of a large number of pachinko balls being thrown at one time on the same screen is described. Since this probability governs gambling, it is regulated by law with the approval of the police and after the approval no one can replace it.

[0009]

However, in a conventional pachinko machine, a central processing unit (C) is used in a pachinko parlor.
(P.U.) and so on, it is difficult to find out if the part has been replaced illegally, and the damage has increased.

As described above, the pachinko machine is installed in a pachinko parlor and the main body of the pachinko machine can be pivotally opened about the hinge. For this reason, an illegal remodeling group illegally unlocks the pachinko machine and opens the pachinko machine, and the central processing unit (CP
U), the read-only memory (ROM), the control board, or the pachinko machine itself was replaced to restore the original state. According to a skilled tampering group, the above work could be completed within tens of seconds.

The main purpose of replacing the components of the pachinko machine is to increase the probability of a "big hit" in which a large number of pachinko balls are made at once by replacing a read only memory (ROM) or the like. Once read-only memory (RO
A pachinko machine whose parts have been replaced, such as M), is usually given a pachinko ball by a member of the remodeling group every day until it is in a so-called "stop" state.

In response to such unauthorized modification, the pachinko parlors or the police mainly open the pachinko machine after closing the store and inspect whether the pachinko machine has been illegally modified.

In the inspection of this unauthorized alteration, it is checked whether a part such as a read-only memory (ROM) is stamped, whether there is a part such as a read-only memory (ROM) whose appearance such as shape and color is abnormal, and Inspection is performed to determine whether a part such as a processing device (CPU) and a read-only memory (ROM) has a serial number, whether the part has a serial number even if the part has a serial number, and the like. I do.

However, the recent unauthorized remodeling of pachinko machines has become extremely precise, and it has become impossible to distinguish the parts from the genuine ones, from the seal stamp to the serial number of the parts, as well as the appearance of the parts.

[0015] For this reason, the illegally modified pachinko machine has been used for a long time, and the damage may be increased.

[0016] Apart from the above problem, pachinko machines are usually discarded after being used in one store. However, the disposal of used pachinko machines costs money for disposal, and some pachinko parlors illegally dump used pachinko machines. This illegal dumping was a social problem. Also, since the used pachinko machines were also a hotbed of illegal use of pachinko machines, there was a need to develop a method of preventing unauthorized use and knowing the original owner of the discarded pachinko machines.

Therefore, the problem to be solved by the present invention is that a component such as a central processing unit (CPU), a read-only memory (ROM), a control board or the like of a pachinko machine or a pachinko machine itself is illegally replaced. Another object of the present invention is to provide a system, a method, and a pachinko machine that can detect this at an early stage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows claim 1 of the present application.
Or 2) “Pachinko machine unauthorized use prevention system”
1 is a diagram showing a relationship and a flow of a configuration according to an embodiment and processing between the components.

The “pachinko machine unauthorized use prevention system” according to the present embodiment comprises a numbering device 2 and a registration judging device 3.
And an inspection device 4.

The numbering device 2 is a device for determining and assigning a part number to be attached to each component of the pachinko machine and a pachinko store number to be attached to at least one component of the pachinko machine where the pachinko machine is to be installed. The numbering device 2 is usually provided by a manufacturer of a pachinko machine.

The internal configuration of the numbering device of this embodiment is as follows.
As shown in FIG. 1, it has a number determination means 2a, a part number / pachinko shop number database 2b, a communication means 2c, and a marking / printing means 2d.

When a predetermined part of a certain pachinko machine is to be assigned a part number and a pachinko shop number to be installed, the numbering device 2 searches the part number / pachinko shop number database 2b by the number determining means 2a and finds the pachinko machine. The part number and the pachinko parlor number to be attached to the parts of the stand are determined. At this time, the used part number and the like are registered as a used number in the part number / pachinko shop number database 2b.
The part number and the like determined by the number determining means 2a are passed to the engraving / printing means 2d and the communication means 2c.

The engraving / printing means 2d is means for actually engraving a part number or the like on a component of the pachinko machine. The marking / printing unit 2d may be a unit that prints a stealth barcode that is printed with ink that reflects only a light beam of a special wavelength and cannot be seen with the naked eye. In the present embodiment, the engraving / printing means 2d is a part of the numbering device 2, but the engraving / printing means 2d may be a device independent of the present system. In other words, the numbering device 2 of the present invention is a “device for numbering” in a broad sense, and may simply determine a part number or the like and “assign” to each component. Alternatively, the number may be determined and then physically stamped on a component of the pachinko machine. Alternatively, the numbering device 2 may control the physically independent marking / printing means 2d.

The communication means 2c is a device for outputting the part number of each part of each pachinko machine and the pachinko store number of the installed pachinko store to the registration judging device 3. Note that, in the present embodiment, “communication means” is used, but as another embodiment of the present invention, “output means” that simply outputs a part number or the like may be used. An example is a printer. In this case, the part number is sent to the registration determination device 3 in paper form.

The registration judging device 3 registers the part numbers and the like of each pachinko machine assigned by the number assigning device 2 as a number set, and when an inquiry is made, the original part number or This is a device that determines whether a number different from the pachinko parlor number exists. The registration judging device 3 is usually provided in a trusted third party. The registration judging device 3 performs only the registration and judgment of the part number and the like, and keeps the secret of the registered contents.

Here, the "number set" is a set of numbers from the part numbers unique to each pachinko machine and the pachinko parlor numbers of the installed pachinko machines. For example, a case number, a control board number, a central processing unit (CPU) number, a read-only memory (ROM) number, a pachinko store number arranged in a certain order, and the like are used.

Performs an operation of inputting a number set related to an inquiry from the inspection device 4 and passing it to the determination unit 3c, and returning a determination result from the determination unit 3c to the inspection device, as described later. Note that the communication unit 3a may be a normal input / output unit that does not rely on “communication”, similarly to the communication unit 2c of the numbering device 2 described above.

The judging means 3c searches the number set database 3b for the inquiry from the number set database 3b, and checks whether there is a number different from the original part number or pachinko parlor number in the number set. And outputs the determination result to the communication means 3a.

At the time of determination, since the pachinko machine number where the pachinko machine was actually installed is included in the inquiry number as described later, the pachinko machine number in the number set is compared with the pachinko machine number. If the pachinko parlor numbers are different, it is determined that the pachinko machines have been replaced, and if not, a number set including the pachinko parlor number is searched from the number set database 3b, and the part numbers for each number set are determined one by one. Should be checked. If the pachinko machine is replaced by the above judgment process,
Any tampering when the part is replaced can be detected.

The detection device 4 inputs the number (part number and pachinko store number) assigned to each part of the pachinko machine and the pachinko store number where the pachinko machine to be inspected is actually installed. This is a device that sends to the registration determination device 3 as a set and obtains a determination result as to whether or not the original number exists in the number set. The inspection device 4 is usually provided in a pachinko parlor where pachinko machines are installed, or in a police or inspection company.

FIG. 1 shows the internal configuration of the inspection apparatus 4 of this embodiment.
As shown in the figure, the communication means 4a, the number input means 4b,
And judgment result output means 4c.

The number input means 4b is an input means having a means for reading numbers, such as a bar code reader, in addition to an input means such as a keyboard for inputting a part number or the like read by a human. The number input means 4b inputs the number assigned to each part of the pachinko machine to be inspected and the pachinko machine number of the pachinko machine where the pachinko machine is actually installed, and uses those data as a number set. Output to communication means 4a.

The communication means 4a sends the number set input from the number input means 4b to the registration judging device 3, performs the judgment processing already described, and obtains the judgment result.

The judgment result output means 4c receives the judgment result by the registration judging device 3 from the communication means 4a and outputs it. The determination result output unit 4c may be any of a unit for outputting to paper, such as a printer, a unit for outputting to a predetermined storage medium, and a display device for displaying the determination result on a screen.

The numbering device 2, the registration judging device 3, and the inspection device 4 may be dedicated devices for performing the above-described processing, but may be a computer (personal computer, computer) controlled by a program to perform the above-described processing. Workstations, minicomputers, etc.).

Next, in step S100, a part number and a pachinko parlor number assigned to a predetermined part of each pachinko machine are registered in the registration judging device as a number set unique to each pachinko machine (step S110). This registration judging device is the same as the registration judging device 3 described in FIG.

Under the above preparation, a pachinko machine is installed in each pachinko parlor (step S120).

After the pachinko machine is installed, when inspecting for any unauthorized modification, the number assigned to the pachinko machine and the number of the pachinko machine where the pachinko machine is installed are input (step S130).

Next, an inquiry is made to the registration judging device as a number set using the number input in step S130 (step S140). Steps S130 and S1 above
The processing of 40 corresponds to the processing by the inspection device 4 in FIG. The registration determination device that has received the inquiry compares the inquired number set with the registered number set (step S150).

Finally, the registration determination device outputs a determination result as to whether or not a number different from the original part number or the pachinko parlor number exists for the number set inquired (step S160).

According to the pachinko machine illegal use prevention system and method described above, the pachinko machine is provided with a number set, so that the pachinko machine is installed at the time of manufacture so that the pachinko machine number and part number are set one by one. Is specified.
Further, these pachinko machine number sets are registered in a fairly confidential state in a registration determination device of a third-party organization.

At the time of use, for example, if the pachinko machine is illegally replaced with its main body, all part numbers including the pachinko machine number change, and, for example, the read-only memory (ROM) is illegally replaced. If so, the part number changes. Therefore, pachinko parlors, police, and the like can immediately detect unauthorized modification at the time of inspection. In addition, the part number etc. of the pachinko machine to be replaced illegally is stamped in advance on the remodeled part, etc.
For printing or the like, these numbers are kept secret by a third-party organization, and since the numbers change one by one for each pachinko machine, it is not possible to produce a large number of modified parts. As a result, illegal alteration is suppressed, and as a result, illegal alteration of pachinko machines can be prevented.

If the part number or the like is printed with a stealth bar code or the like that cannot be visually confirmed, the illegal remodeling group can empirically determine the pachinko store number and the part because the part number and the like cannot be visually confirmed. It is possible to prevent the user from perceiving regularity of numbers (method of assigning numbers) and the like.

Regarding the problem of illegal dumping of used pachinko machines, when there is an illegal dumping operation, the illegally dumped pachinko machine is determined from the pachinko store number attached to the illegally dumped pachinko machine. This can suppress illegal dumping.

The above is a system and a method for ascertaining unauthorized alteration of a pachinko machine through determination of registration of a number set to a reliable third party. Next, registration determination to a third party is performed. do not need. Pachinko machine illegal use prevention system and its prevention method (method using public key and secret key)
Will be described below.

The system and method for preventing unauthorized use by using a public key and a secret key can be combined with the system method for registering and judging a number set to the above-mentioned third party organization. In the embodiment, a system and a method combining these will be described.

Here, the principle of the secret key and the public key and a mechanism for preventing unauthorized alteration will be described briefly.

Now, two large prime numbers p and q are selected (for example, a prime number of about 512 bits), and the product is represented by n (n = p ·
q). On the other hand, if a certain number e is selected, a number d that satisfies the relationship of the following equation (1) can be determined.

[0083] Here, assuming that a certain number X belongs to a multiplicative group Zn of order (p−1) (q−1), by Lagrange theorem,

[0084] Holds. Similarly, for some integer m ≧ 1,

[0085] Holds. The following equation (4) can be derived from the equation (3).

[0086] Here, ed = m (p−1) (q−1) +1... (5) according to equation (1).

[0087] Here, e and n are public keys of a pachinko machine manufacturer,
Assuming that d, p, and q are the plaintext numbers such as the secret key and the part number of X, the numbers can be encrypted or decrypted as follows.

Assuming that the number encrypted with the secret key d of the pachinko machine maker is Z,

[0089] In order for the pachinko parlor, the police, and the inspection company to decrypt the encrypted number Z, the pachinko machine manufacturer may raise the encrypted number Z to the power e using the public key e of the pachinko machine manufacturer. That is, using equation (6)

[0090] Thus, the plaintext number X can be decrypted from the encrypted number Z.

The public key e of the pachinko machine maker is disclosed to pachinko parlors, police, inspection companies, etc., so that the person who intends to inspect can use it arbitrarily, and can easily obtain the plaintext part number from the encrypted number. Can be restored.

On the other hand, even if an unauthorized remodeling group attempts to generate an encryption number from a plain text part number in order to attach the remodeled part, the encryption number may be generated from a large number of combinations of d, p, and q. It can be said that it is almost impossible.

According to this method, anyone who knows the public key of the manufacturer can detect unauthorized alteration by a simple calculation without consulting a third party at the time of inspection.
In addition, various information such as a model number, a manufacturing date, a serial number, and the like can be included in the part number in plain text.

In the pachinko machine tampering prevention system 5 of this embodiment, the enciphered number or the decrypted plaintext number is used as a number set in the registration determination device 3 just in case.
, And the determination can be made by the registration determination device 3. If the determination method based on the number set is used together, the same system enables even a person who cannot decrypt data to detect the illegally modified part by inquiring of the registration determination device 3.

The description of the configuration and the processing of the pachinko machine unauthorized use prevention system 5 is completed above. Next, a description will be given of the “pachinko machine unauthorized use prevention method”.

FIG. 4 shows the flow of processing of the “pachinko machine illegal use prevention method” according to claims 7 and 8 of the present application.

As shown in FIG. 4, in this method, first, for each pachinko machine, a part number unique to each part at the time of its manufacture, and a pachinko store number of the pachinko machine to be installed are encrypted using a secret key of the pachinko machine manufacturer. Then, each part is stamped and printed (step S200).

Next, the part number assigned in step 200, the encrypted number of the pachinko parlor number, or both the encrypted number and their plaintext numbers are registered as a number set in a predetermined registration determining device (step 200). S21
0).

Under the above preparation, a pachinko machine is installed in each pachinko parlor (step S220).

After the pachinko machine has been installed, there are two methods for inspecting whether there is any unauthorized alteration: a judgment method by the registration judgment device (steps S230 to S260) and a judgment method by decryption (steps S300 to S310). is there.

First, in the case of the method of judging by the registration judging device, the number given to the pachinko machine and the pachinko parlor number of the installed pachinko parlor are inputted (step S23).
0).

Next, the number entered in step S230 is inquired as a number set to the registration judging device (step S240). In response to the inquiry, the registration judging device compares the inquired number set with the registered number set (step S250), and replaces the original part number or pachinko parlor number in the inquired number set. A determination result as to whether or not a different number exists is output (step S260).

On the other hand, in the determination method based on decryption, at the time of checking for the presence or absence of unauthorized alteration, the pachinko machine is decrypted into a plain text number using the public key of the manufacturer as described above (step S300).

Finally, it is possible to determine the presence or absence of unauthorized modification based on the meanings of the decrypted part number and pachinko parlor number (step S310).

In the "method of preventing unauthorized use of pachinko machines" in FIG. 4, the registration of the number set in the registration judging device (step S210) and each process of judgment by the registration judging device (steps S230 to S260) are omitted. What can be done is clear from the description of FIG.

[0106]

According to the "pachinko machine unauthorized use prevention system" of claims 1 and 2 and the "pachinko machine unauthorized use prevention method" of claims 5 and 6, each of the predetermined components of each pachinko machine is provided. The pachinko parlor number of the pachinko parlor where each pachinko parlor is installed is stamped and printed on each part of the pachinko parlor, and these part numbers etc. are set as a set of them. If any of the components that make up the pachinko machine or the pachinko machine itself is replaced improperly because it is registered in the registration judgment device in a secret state, the part replaced by collation with the number set is It can be detected immediately.

The unauthorized remodeling group cannot know in advance the part numbers of the parts to be remodeled. Even if it knows several part numbers, it is not uniform and cannot manufacture a large number of remodeled parts. , Even if modified illegally, it will be found immediately. As a result, an illegal remodeling action can be effectively suppressed, and as a result, illegal remodeling of the pachinko machine can be prevented.

Also, regarding the problem of illegal dumping of pachinko machines, since the number of the installed pachinko machine is given to the pachinko machines, the pachinko machine that has been illegally dumped can be identified, and thereby the illegal dumping of pachinko machines can be performed. It can be suppressed effectively.

According to the “pachinko machine unauthorized use prevention system” of claims 3 and 4 of the present application and the “pachinko machine unauthorized use prevention method” of claims 7 and 8, the encryption attached to each component of the pachinko machine. The pachinko machine manufacturer's public key to decrypt it into a plaintext part number, etc.
According to the meaning of the part number in the plain text, the presence or absence of unauthorized modification can be immediately detected.

Since the generation of the encryption number requires a secret key known only to the pachinko machine manufacturer, the manufacture of remodeled parts by the unauthorized remodeling group can be prevented.

As described above, if the pachinko parlor number is included in the plaintext number, illegal dumping can be effectively suppressed.
