Description

  The present invention relates to a gaming machine control semiconductor device, an inspection apparatus for gaming machine control semiconductor device, and an inspection method for gaming machine control semiconductor device.

  Various regulations are imposed on laws and ordinances for gaming machines such as pachinko machines and pachislot machines that have a gambling nature. A gaming machine control semiconductor device (hereinafter referred to as a “gaming machine control chip”) is a component that plays a central role in controlling a gaming machine to operate properly within a range stipulated by laws and regulations. A criminal act of intentionally operating a gaming machine so as to be advantageous to the player by replacing such a gaming machine control chip with a counterfeit or illegally modified one has been a problem.

  Conventionally, an effort has been made to find a characteristic part in which characters and symbols printed on the surface of a semiconductor package are slightly different from those of a regular product, and to find a counterfeit product or an illegally modified chip. In such a method, once a characteristic part different from a regular product is known, a counterfeit product or a tampered product can be found relatively easily. However, as counterfeiting and tampering techniques become more sophisticated, it has become difficult to find counterfeit products and tampered chips in this primitive way.

  Various countermeasures have been proposed in order to deal with such problems, and one of them is assigned an ID number that can individually identify each gaming machine control chip. There is a method of determining whether or not the gaming machine control chip is a regular chip by storing it in a storage means inside the chip and reading out this ID number from the outside by a predetermined method as necessary after shipment. It has been proposed (for example, JP 2003-299862 A).

  The method of assigning individual ID numbers to gaming machine control chips is certainly useful in that it can reliably discriminate forged chips and illegally modified chips. However, in order to carry out this method, it is necessary to read the ID number from the storage means inside the chip, and therefore a dedicated reading device is always required to determine whether or not the chip is a legitimate chip. In addition, as such a forgery prevention method for storing such individual ID numbers in the storage means is known, the appearance of such a forgery group is expected, and a new forgery prevention method is required.

  The present invention has been made based on such a background, and an inspection method capable of distinguishing a counterfeit product or a tampered product of a gaming machine control chip relatively easily, and an unprecedented inspection method It is another object of the present invention to provide an inspection apparatus and a gaming machine control chip for carrying out this method.

Alternatively, by storing both in the chip, this can be used for determining the authenticity of the chip, and a quick and accurate inspection is possible.

  Further, the first identification information printed on the surface of the package and the second identification information stored inside the chip are registered in the database in association with each other, so that the other is searched based on one of them. Therefore, a forged gaming machine control semiconductor device or a tampered gaming machine control semiconductor device can be reliably found.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing information printed on an external surface of a gaming machine control semiconductor device (hereinafter referred to as “gaming machine control chip”) according to an embodiment of the present invention.

  In FIG. 1, a print area indicated by reference numeral 10 includes a product number (N), a lot number (L), and a manufacturing date (D), which are examples of “first identification information” recited in the claims. ), A serial number (S), and other management numbers (K) are printed as characters made up of numbers and alphabets. Therefore, the person concerned with this product can know what this gaming machine control chip is by looking at the information printed in this printing area 10.

  Among the first identification information, the “serial number (S)” is a number assigned individually to each gaming machine control chip. For this reason, the first identification information is also information unique to each gaming machine control chip as a whole, and each gaming machine control chip can be uniquely specified by the first identification information.

  In FIG. 1, a check code (H) is printed in a check code printing area indicated by reference numeral 12. This check code (H) is generated based on the first identification information printed in the print area 10. Specifically, the check code (H) is obtained by calculating the hash function based on the first identification information as a variable, and expressing the obtained value as a numerical value.

  By printing such a check code (H), for example, in order for a person who forged the gaming machine control chip to have an appearance similar to the actual one, a print area 10 and a check code print area 12 on the package surface are used. Even if numbers and alphabets are printed in the same way, they are not related to the latter being generated from the former by the calculation of the hash function. Therefore, an operation for obtaining a hash function is performed based on the value printed in the printing area 10 of the gaming machine control chip on the market, and the obtained result is compared with the value printed in the check code printing area 12. Thus, the authenticity of the gaming machine control chip can be determined based on the print data.

  In FIG. 1, in a code printing area indicated by reference numeral 14, a mechanically readable code encoded with characters and numbers is printed. In this embodiment, a two-dimensional code (also called “two-dimensional barcode”) is used as such a code. The two-dimensional code can be printed using a general printing technique for printing on the surface of the semiconductor package. In addition, it is difficult to recognize what content is contained at a glance at a glance, but it can be read accurately and at high speed by an optical reading device (hereinafter referred to as “reader”).

  In place of the two-dimensional code, a one-dimensional bar code that can be optically read can also be used. In addition to those that can be read optically, such as barcodes and two-dimensional codes, elements that can be read electrically, such as non-contact IC chips, can be added to the gaming machine control chip, or magnetically What can be read may be attached to the gaming machine control chip.

  In the present embodiment, both the first identification information printed in the print area 10 and the check code (H) are included as data that is the basis of the two-dimensional code. As a result, when the two-dimensional code is read using a reader and restored to the original character or number data that can be recognized by humans and displayed on a computer display or the like, the first identification information and the check code (H) Both appear. The product number (N), lot number (L), production date (D), serial number (S), other management number (K), which are the first identification information actually printed in the print area 10, Then, by comparing with the check code (H) printed in the check code printing area 12, it is possible to determine the authenticity of the gaming machine control chip.

  Furthermore, the gaming machine control chip according to the present embodiment can write the ID number in its internal memory. This ID number is an example of “second identification information” recited in the claims.

  FIG. 2 is a block diagram showing an internal configuration of the gaming machine control chip according to the present embodiment. As shown in the figure, ID storage means c11a in the storage means c11 of the internal memory is provided inside the gaming machine control chip, and an ID for individually identifying each gaming machine control chip is provided here. Numbers can be stored.

  Writing of the ID number to the ID storage means c11a and reading of the ID number from the ID storage means c11a are performed via the external input / output means c14 (including the SC terminal and the BRC terminal) and the bus BUS1, and are written once. The ID number cannot be erased or rewritten except by using a special method.

  The ID number is described in detail in the patent application filed by the present applicant, Japanese Patent Application No. 2002-109658 (Japanese Patent Laid-Open No. 2003-299862), and Japanese Patent Application No. 2003-370884. Then, the explanation is omitted.

  This ID number is not only stored in the internal memory of the gaming machine control chip but also registered in a predetermined management database in association with the first identification information. That is, each gaming machine control chip is registered in the management database in association with the first identification information and the second identification information.

  FIG. 3 is a flowchart showing an overall flow of work from manufacture to shipment of the gaming machine control chip according to the present embodiment. First, similarly to the conventional work steps, a wafer is manufactured (S301) and a chip is assembled (S302). When the chip is assembled, print data is created (S303). Here, “print data” refers to the product number (N), lot number (L), production date (D), serial number (S), and other management number (K) printed in the print area 10 shown in FIG. ) And the check code (H) printed in the check code print area 12.

  Next, the created print data is actually printed on the package surface of the gaming machine control chip (S304). This step includes printing of the two-dimensional code created from the print data created in S303.

  After printing, the print data is inspected at this stage (S305). That is, the original information is restored by actually reading the two-dimensional code with a reader, and the contents are compared with the contents printed in the print area 10 and the check code print area 12. If both match, the result is accepted, and if they do not match, the product is discarded as a defective product (S310).

  Subsequently, an operation test of the gaming machine control chip is performed (S306). This work step is also similar to the conventional one. Then, for only the gaming machine control chip that has passed this test, a process of writing the ID number into its internal memory is performed (S307). When the first identification information or the function value is stored in the chip, it is written in the chip in this step.

  Up to this point, the first identification information (product number (N), lot number (L), production date (D), serial number (S), other management number (K) is displayed on the package surface of the gaming machine control chip. ), A check code (H), and an optically readable code (here, “two-dimensional code”) are printed, and the second identification information is written inside the gaming machine control chip. .

  Subsequently, data in which the first identification information and the second identification information are associated with each other is created and registered as one record in the management database 30 described later (S308). As a result, the first identification information printed on the surface of the gaming machine control chip and the second identification information written inside the gaming machine control chip are associated with each other. By accessing, it becomes possible to identify the other from one.

  The gaming machine control chip for which the above processing has been completed is shipped to a user, that is, a gaming machine manufacturer that manufactures a gaming machine using this gaming machine control chip (S309).

  Next, the inspection after the gaming machine control chip is shipped and actually mounted on the gaming machine and distributed to the market will be described.

  FIG. 4 is a diagram showing an outline of the entire gaming machine inspection system according to the present embodiment. This system includes a two-dimensional code reader (simply called “reader”) 22 that reads the two-dimensional code 14 printed on the gaming machine control chip, and a dedicated terminal provided on the gaming machine 20 on which the gaming machine control chip is mounted. An ID number reading device 24 for connecting and reading an ID number unique to the gaming machine control chip, a computer terminal 26 to which the reader 22 and the ID number reading device 24 are connected, a computer terminal 26 and a network 28 such as the Internet. Management database terminals 30 connected to each other.

  In the system shown in FIG. 4, only the reader 22 and the computer terminal 26 can constitute an inspection apparatus that performs the inspection described later, and a network 28 and a management database 30 are added to the inspection apparatus to constitute another inspection apparatus. Can do. Further, the ID number reading device 24 can be operated independently without being connected to the computer terminal 26. In this case, the read ID number is displayed on its own display unit 24a.

  Here, the reader 26 is an example of the “machine reading unit” described in the claims, and the ID number reading device 24 is an example of the “reading unit” described in the claims. The computer terminal 26 is an example of “restoring means” and “display means” described in the claims, and the management database 30 is an example of “database means” described in the claims. . The computer terminal 26 also has a function of performing an operation for obtaining a hash function using the first identification information restored from the two-dimensional code 14 as a variable, and comparing the obtained result with a check code.

  FIG. 5 is a flowchart showing a processing procedure for authenticity determination inspection after shipment using a two-dimensional code.

  First, a two-dimensional code is read by the reader 22 (S501). Then, the contents of the computer terminal 26 to which the reader is connected are restored, and the first identification information and the check code (H) are displayed on the display (display unit) 26a (S502). At this stage, if the two-dimensional code cannot be restored normally, the characters in the print area 10 and the check code print area 12 are printed from somewhere. It is possible to detect counterfeit products that have only been printed.

  In fact, even if the trademark or product number (N) is imitated, and it looks counterfeited at first glance, the two-dimensional code is very detailed in each component. Since it is difficult to accurately reproduce a fine part to such an extent that it can be read properly, it is possible to detect counterfeiting effects or detect counterfeiting even by performing such an inspection.

  After restoring the first identification information in the print area 10 and the check code in the check code print area 12 from the two-dimensional code, the computer terminal 26 performs an operation for obtaining a hash function using the restored first identification information as a variable (S503). This is compared with the restored check code (H) (S504). As a result, if they match, it is determined that the content of the printed two-dimensional code is normal (S505), and if they do not match, it is determined that the content is abnormal (S506). The abnormal case here is an operation for obtaining a hash function for a certain part of the character information (here, the first identification information) even though a two-dimensional code can be generated based on some character information. This corresponds to the case where a person who did not know that a calculation for obtaining another part (check code) is performed or who did not know the specific calculation method of the hash function forged such a chip.

  Subsequently, the data displayed on the display 26a after restoring the two-dimensional code and the contents actually displayed in the print area 10 and the check code print area 12 on the package surface of the gaming machine control chip are displayed as an inspector. Are visually compared (S507). If they match, it is determined as a normal chip (S508), and if they do not match, it is determined as a forged chip (S509). By performing a visual comparison inspection, the product number (N) can be imitated, but only a two-dimensional code that is difficult to duplicate can be taken from somewhere and a counterfeit chip that is attached to the surface can be found. it can.

  FIG. 6 and FIG. 7 are flowcharts showing the process of authenticity determination inspection for the gaming machine control chip using the two-dimensional code reader 22 and the ID number reading device 24. This inspection can be performed in an environment where both the two-dimensional code of the gaming machine control chip and the ID number can be read out, and further, these can be transmitted to the management database 30 via the network 28 and a search process can be requested. It is.

  In FIG. 6, S601 to S606 are the same as S501 to S506 in FIG. When the content printed as the two-dimensional code in S605 is normally displayed, the ID number reading device 24 is used to read the ID number from the gaming machine control chip (S607).

  Here, it is determined whether the ID number can be read normally (S608). In this determination, first, whether or not a protocol for communication between the gaming machine control chip and the ID number reading device 24 has been established, and the ID number read as established has a predetermined format (number of digits, etc.) Determine if the content is normal. If the data cannot be read normally, it may be counterfeited and an abnormal ID number is displayed (S613).

  On the other hand, if the data can be read normally in S608, the computer terminal 26 transmits a search request to the management database 30 via the network 28 (S609). At the time of this search request, both the data obtained by restoring the two-dimensional code and the ID number are transmitted to the management database. Search processing in the management database is shown in FIG.

  When the computer terminal 26 receives the search result from the management database 30 (S610), it is determined whether or not the search result is normal (S611). If the search result is normal, the search content is displayed on the display 26a (S612). If so, the contents of the abnormality are displayed (S614).

  Here, as an abnormal case, when neither the contents of the two-dimensional code restored and the ID number exist in the database, or when only one of these exists, each of them is certainly present in the database. May not be registered in association with each other.

  When normal collation contents are displayed on the display 26a in S612, the inspector can confirm the contents displayed on the display and the actual package surface of the gaming machine control chip as in S507 to S509 of FIG. It is visually confirmed that the contents displayed in the print area 10 and the check code print area 12 match. If the two do not coincide with each other, the two-dimensional code and the ID number are taken from somewhere, but the printing area 10 and the check code printing area 12 are considered to be counterfeit chips that are similar to those.

  Next, search processing in the management database 30 shown in FIG. 7 will be described. This process is started by the search request in S609 shown in FIG. First, when a search request is received from the computer terminal 26 to which the two-dimensional code reader 22 and the ID number reading device 24 are connected (S701), the management database 30 is searched. This search is performed using either one or both of the two-dimensional code restoration information printed on the package surface of the gaming machine control chip and the ID number.

  Then, it is checked whether or not the data exists (S703). If the data does not exist, the fact that the corresponding data does not exist is transmitted as a search result to the computer terminal 26 via the network 28 (S710).

  On the other hand, if either one of the two-dimensional code restoration data or ID number exists, the other corresponding data is extracted from the association data, and the extracted data pair and the data pair requested to be searched And match. As a result, if the collation results match, the corresponding record is set in the transmission buffer (S706). If the collation results do not match (if only one of the two-dimensional code restoration data and the ID number matches), The mismatched pair record is set in the transmission buffer (S709). The data set in the transmission buffer is transmitted to the computer terminal 26 at a predetermined timing (S710).

  FIG. 8 is a flow chart showing a standard work procedure when inspecting whether or not a gaming machine control chip used for each gaming machine in a gaming store or the like is genuine. The inspector has a dedicated ID number reading device 24, which is used for the inspection.

  First, the ID number reading device 24 is connected to the connection terminal 20a of the gaming machine to be inspected, and the ID number stored in the internal memory is read. As described above, in order to read out the ID number, it is necessary to establish a predetermined protocol between the ID number reading device 24 and the gaming machine control chip. it can.

  In step S801, it is determined whether the ID number can be read. If the ID number can be read out, the management database is inquired based on the read ID number to check whether the gaming machine control chip is supposed to be in the gaming store. Can do.

  On the other hand, when the ID number cannot be read because the protocol is not established or the like, the appearance information of the gaming machine control chip, that is, the first identification information (product number (N), lot number (L), manufacturing date, Based on (D), serial number (S), other management number (K)) and check code (H), the relevant organization that owns the management database is inquired by telephone or the like (S803). If there is no such appearance information (S804), the gaming machine control chip is seized as a counterfeit, and a detailed investigation is performed as necessary (S812).

  If the appearance information can be recognized in S804, the relevant institution is inquired based on the appearance information, and the gaming machine manufacturer to which the gaming machine control chip is shipped is specified (S805). Since the gaming machine manufacturer usually records the ID number of the used gaming machine control chip in some form, it inquires of the manufacturer about the ID number (S806). At the same time, the gaming machine manufacturer records the ID number of each gaming machine control chip, the gaming machine using the gaming machine control chip, and the gaming store to which the gaming machine is shipped in association with each other. The game store is also inquired, and it is determined whether the game store that should be the shipping destination matches the game store where the game machine is actually installed (S807). As a result, if the amusement store matches, it is considered that either the faulty product whose ID number cannot be read from the gaming machine control chip or the one whose appearance is completely counterfeited, and a detailed investigation is performed ( S813).

  On the other hand, if the stores do not match, the gaming machine control chip is suspected of being forged, so the gaming machine control chip is seized (S808), and the authenticity of the gaming machine control chip is detailed in a tester or the like. Inspect (S808). If it is determined to be a genuine product, the non-approved modified gaming machine is broken, that is, the gaming machine control chip is replaced with another gaming machine without obtaining the necessary approval. It is determined that the device is malfunctioning (S814). If it is determined in S810 that the product is not a regular product, it is determined that the chip has a counterfeit appearance (S811), and necessary measures are taken.

  FIG. 9 is a flowchart showing a standard work procedure for determining the authenticity of the gaming machine control chip based on the appearance information printed on the package of the gaming machine control chip.

  First, the appearance information printed on the package of the gaming machine control chip, that is, the first identification information printed on the print area 10 of the package and the check code (H) printed on the check code print area 12 are visually checked. Read (S901). Based on the read appearance information, an inquiry is made to the inspection institution managing the chip manufacturer or the chip database or the manufacturer of the gaming machine control chip by telephone or the like (S902), and the gaming machine control registered along with such information Whether or not the chip exists is checked (S903). If there is nothing registered with such information, the game machine control chip is seized as being a counterfeit product, and necessary measures are taken such as strict investigation.

  On the other hand, if it is determined in S903 that there is a gaming machine control chip registered with such information, the inspection engine or the gaming machine control chip manufacturer shipped the gaming machine control chip based on the information. A gaming machine manufacturer is specified (S904).

  Then, the game machine manufacturer is inquired about the associated ID number (S905). It is checked whether or not the shipping-destination amusement store known from the ID number matches the store where the gaming machine is actually installed (S906), and if it matches, it is properly installed in the amusement store. (S912).

  In S906, if the stores do not match, the gaming machine control chip is suspected of being counterfeit, so the chip is seized (S907), and the authenticity of the chip is inspected internally by a tester or the like (S908). As a result, when it is determined that the product is a regular product (S909), it is determined that the product is a failed product of the unauthorized change gaming machine (S913). On the other hand, when it is determined that the chip is not a regular product (S909), it is determined that the chip has a counterfeit appearance, and necessary measures are taken.

  As described above, the first identification information is printed on the package surface of the gaming machine control chip, and the check code (H) is generated by performing an operation for obtaining a hash function using the first identification information as a variable. In addition, by printing on the package surface, a considerable forgery prevention effect can be obtained.
