Description

Specification

Article management system, article management method, information processing terminal, and information recording medium

TECHNICAL FIELD [0001] The present invention relates to an article management system, an article management method, an information processing terminal, and an information recording medium for managing the association of a plurality of articles each having unique identification information, and in particular, a plurality of articles. The present invention relates to an article management system, an article management method, an information processing terminal, and an information recording medium, in which at least one of them is an information recording medium.

Background art

[0002] The conventional measures for illegally disassembling a gaming table unit is one example of managing the association of a plurality of items. As a measure against unauthorized disassembly of this gaming unit, whether or not the gaming unit has been illegally disassembled by attaching a seal sticker to the joint of the unit and checking the trace of the seal seal being peeled off. Judgment is being made. In such seals, in order to make it easier to confirm the peeled traces, for example, a seal having a structure that, when peeled, causes the seal seal to be broken, such as making a cut extending in the peeling direction. It is thought.

[0003] In recent years, a non-contact type IC label capable of writing and reading information in a non-contact state has been considered as a sealing seal as described above. A non-contact IC label can write information, unlike a sealed label with a barcode printed on its surface. Therefore, for example, by writing identification information such as an article ID given to an article to be sealed, it is possible to increase the reliability of the determination of unauthorized disassembly. In such a non-contact type IC label, the antenna and the IC chip break when peeled off from the article, making it impossible to write and read information, so that it can be detected reliably. For example, it is described in Japanese Patent Publication No. 2000-334154.

[0004] As described above, in order to prevent illegal disassembly of the gaming machine unit, the association between the gaming machine unit and the seal sticker attached thereto is used. When the seal sticker is peeled off from the gaming unit, that is, the gaming unit and the sealing sheet attached thereto. If the association with the game is resolved, it is determined that the game unit has been disassembled illegally.

[0005] In the non-contact information recording medium that can write and read information in a non-contact state, such as the above-described non-contact type IC label, so-called RFID (Radio Frequency Identification), in recent years, the sealing as described above It is used not only for labels but also for inventory management of goods such as products and distribution status management. Such RFID is attached to an article as a label or tag, and the article is managed by writing information about the article. In other words, the association between RFID and articles is also used in general article management using RFID.

[0006] However, in the one described in Japanese Patent Publication No. 2000-334154, after the non-contact type IC label is peeled off from the product, a new non-contact type IC label in which information about the product is written is newly provided. When pasted as a sealed label, there is a problem in that it is impossible to detect unauthorized disassembly of an article, that is, alteration of correspondence between plural articles.

[0007] In addition, when managing an article using an information recording medium, if an information recording medium on which unauthorized information is written is attached to the article, the illegally written information manages the article. For example, there is a problem that food production areas and distribution routes are falsified.

Disclosure of the invention

In this embodiment, as shown in FIG. La, unauthorized disassembly of a unit 20 in which a substrate 21 is housed in a case 23 is detected. The RFID label 30, which is an information recording medium, is attached to the joint of the case 23, and the association between the RFID label 30 and the unit 20 is managed by using the information processing terminal 10. Detected.

[0020] In the unit 20, the substrate 21 is housed in a case 23 that can be opened at the joint, and the RFID label 30 is attached as a sealing seal in a state where the joint is closed. The RFID label 30 is an IC chip (not shown) capable of writing and reading information in a non-contact state, and an antenna (not shown) connected to the IC chip and used for communication using a predetermined frequency. (Not shown) is provided on the label substrate. The IC chip contains a unique identifier (UID) that is unique to the RFID label 30 when the RFID label 30 is manufactured. The communication method via the antenna can be set as appropriate, such as the electromagnetic induction method using the 13.56 MHz frequency band and the radio wave method using the 2.45 GHz frequency band. Further, a serial number 22 which is identification information unique to the unit 20 is displayed on the substrate 21 by silk printing or the like.

As shown in FIG. Lb, the information processing terminal 10 includes an operation unit 11, an information reading unit 12, an encryption unit 13, an information writing unit 14, a decryption unit 15, and a key acquisition unit 16. And a collation unit 17 and an output unit 18.

The operation unit 11 is for inputting a serial number 22 of the unit 20 displayed on the board 21 with a plurality of key button forces capable of inputting numbers and alphabets.

[0023] The information reading unit 12 can read information written on the RFID label 30 in a non-contact state, and reads the UID and encryption key information written on the RFID label 30.

The encryption unit 13 encrypts the serial number 22 of the unit 20 input to the operation unit 11 and the UID of the RFID label 30 read by the information reading unit 12 together.

[0025] The information writing unit 14 can write information to the RFID label 30 in a non-contact state. The information encrypted by the encryption unit 13 is written in the RFID label 30 as encryption information.

The decryption key unit 15 decrypts the cipher key information read from the RFID label 30 by the information reading unit 12.

The key acquisition unit 16 acquires an encryption key for encrypting information in the encryption key unit 13 and a decryption key for decrypting the encryption key information in the decryption unit 15. . For example, it can also be obtained by reading the encryption key or decryption key written on the card, which also serves as a card reader.

[0028] The verification unit 17 includes the serial number 22 of the unit 20 decrypted by the decryption unit 15 and the UID of the R FID label 30 and the serial number 22 of the unit 20 input to the operation unit 11. And the UID of the RFID label 30 read by the information reading unit 12 is collated.

The output unit 18 displays and outputs the collation result in the collation unit 17.

[0030] Hereinafter, an unauthorized disassembly detection method for the unit 20, which is an article management method using the article management system configured as described above, will be described.

First, a process when assembling the unit 20 will be described.

[0032] FIG. 2 is a flowchart for explaining processing when the unit 20 is assembled in the article management system shown in FIGS. La and lb.

The unit 20 is assembled by housing the substrate 21 in the case 23. At that time, in step S 1, the serial number 22 of the unit 20 displayed on the substrate 21 is input to the operation unit 11 of the information processing terminal 10. The serial number 22 is unique identification information assigned to each unit 20 and is displayed on the board 21 in a state where it can be seen.

[0034] Next, the joint portion of the case 23 containing the substrate 21 is closed, the RFID label 30 is attached to the joint portion, the case 23 is sealed, and in step S2, the information processing terminal 10 is turned on. Used to read the UID of RFID label 30. At this time, when the information processing terminal 10 is put on the R FID label 30, the information reading unit 12 of the information processing terminal 10 reads the UID written on the RFID label 30 in a non-contact state.

The serial number 22 of the unit 20 input to the operation unit 11 and the UID of the RFID label 30 read by the information reading unit 12 are given to the encryption unit 13. In step S3, the serial number 22 of the unit 20 input to the operation unit 11 and the information reading unit 12 read it. The encrypted UID of the RFID label 30 is encrypted by the encryption unit 13 together. Note that the encryption key in the encryption key unit 13 is performed using the encryption key acquired by the key acquisition unit 16. The encryption key for the encryption key in the encryption key unit 13 is supplied by, for example, a card. The encryption key for the encryption key in the encryption key part 13 is written on the card, and the encryption key written on the card is read by the card reading part of the key acquisition part 16, The key acquisition unit 16 acquires the encryption key. The information encrypted by the encryption unit 13 is given to the information writing unit 14. The encryption key can be acquired by the key acquisition unit 16 when the encryption unit 13 encrypts the serial number 22 of the unit 20 and the UID of the RFID label 30 together, or the information processing terminal 10 It may be acquired in advance and stored.

[0036] After that, when the information processing terminal 10 is put on the RFID label 30, in step S4, the information writing unit 14 of the information processing terminal 10 converts the information given from the encryption unit 13 into the encryption key information. Is written to the RFID label 30 in a non-contact state.

FIG. 3 is a diagram showing the configuration of the storage area of the RFID label 30 shown in FIG.

The storage area of the RFID label 30 shown in FIG. 1 has a UID of the RFID label 30 written therein, as shown in FIG. 3, and a first storage area 31 in which only information can be read, and information writing. It consists of a second storage area 32 that can be loaded and read. The encrypted information written from the information processing terminal 10 is written in 32 storage areas in which information can be written and read. That is, the encrypted information written to the RFID label 30 is written to a storage area different from the UID of the RFID label 30.

[0039] In this way, when assembling the unit 20, the information processing terminal 10 is used to encode and encrypt the serial number 22 of the unit 20 displayed on the board 21 and the UID of the RFID label 30 together. Write to the RFID label 30 as information.

[0040] Next, processing when confirming unauthorized disassembly of the unit 20 will be described.

[0041] FIG. 4 is a flowchart for explaining processing when confirming unauthorized disassembly of the unit 20 in the article management system shown in FIGS. La and lb.

[0042] When confirming the unauthorized disassembly of the unit 20, first, when the information processing terminal 10 is put on the RFID label 30, the information reading unit 12 of the information processing terminal 10 performs RF in step S11. The encryption key information and UID written on the ID label 30 are read in a non-contact state.

[0043] The encrypted information read from the RFID label 30 by the information reading unit 12 is provided to the decryption unit 15 of the information processing terminal 10. In step S12, the encryption key information read from the RFID label 30 by the information reading unit 12 is decrypted by the decryption key unit 15. It should be noted that the decryption of the encryption key information in the decryption key unit 15 is performed using the decryption key acquired by the key acquisition unit 16 in the same manner as the encryption in the encryption key unit 13. The decryption key for decryption in the decryption unit 15 is supplied by, for example, a card. In the card, a decryption key for decryption in the decryption key unit 15 is written, and the decryption key written in the card is read by the card reading unit in the key acquisition unit 16 to obtain a key. The obtaining unit 16 obtains the decryption key. The acquisition of the decryption key in the key acquisition unit 16 may be performed when the encryption key information read from the RFID label 30 is decrypted by the decryption key unit 15, or may be acquired in advance by the information processing terminal 10. It may be acquired and stored. The encryption key for encrypting information in the encryption unit 13 and the decryption key for decrypting the encrypted information in the decryption unit 15 use a common key by a common key encryption method. However, a secret key and a public key based on a public key cryptosystem may be used, but the latter is preferable in terms of ease of key management. That is, a secret key based on a public key cryptosystem is used as an encryption key for encrypting information in the encryption unit 13, and a decryption key for decrypting the encryption key information in the decryption key unit 15. It is preferable to use a public key by a public key cryptosystem.

[0044] When the decryption unit 15 decrypts the encryption key information read from the RFID label 30, the serial number 22 of the unit 20 and the UID of the RFID label 30 are provided to the verification unit 17. .

Next, in step S 13, the serial number 22 of the unit 20 displayed on the substrate 21 is input to the operation unit 11 of the information processing terminal 10.

[0046] The serial number 22 of the unit 20 input to the operation unit 11 and the UID read from the RFID label 30 by the information reading unit 12 in step S11 are given to the verification unit 17. In step S14, the serial number and UI D given from the decryption unit 15 are compared with the serial number and UID given from the operation unit 11 and the information reading unit 12. Checked in part 17.

[0047] After that, in step S15, the collation result in the collation unit 17 is given to the display unit 18 and displayed. The collation result display output is such that, for example, the serial number and UID given from the decryption unit 15 match the serial number and UID given from the operation unit 11 and the information reading unit 12, respectively. In such a case, it is displayed that the two match, and the serial number and UID given from the decryption unit 15 match the serial number and UID given to the operation unit 11 and the information reading unit 12 as well. In this case, it may be displayed that both are in agreement! In addition, the serial number and UID given from the decryption key unit 15 and the serial number and UID given from the operation unit 11 and the information reading unit 12 may be displayed on the output unit 18! / ,.

[0048] Here, if the unit 20 has not been illegally disassembled, the unit 20 has the same RFID label 30 as the RFID label 30 attached when the unit 20 force S is assembled. It should be. Therefore, if the UID written as the encryption information on the RFID label 30 is decrypted, the decrypted UID must match the UID of the RFID label 30 read from the RFID label 30 in step S11. Become. Similarly, when the serial number written as encryption key information in the RFID label 30 is decrypted, the decrypted serial number is stored in the unit 20 input to the operation unit 11 in step S13. It will match the serial number 22. On the other hand, when the unit 20 is illegally disassembled, an RFI D label 30 different from the RFID label 30 attached when the unit 20 is assembled is attached to the unit 20. Therefore, even if the serial number 22 of the unit 20 is encrypted and written to the RFID label 30 newly attached to the unit 20 in the same manner as described above, it is written to the RFID label 30 as encryption key information. If the UID is decrypted, the decrypted UID does not match the UID of the RFI D label 30 read from the RFID label 30 in step S11!

[0049] If the board 21 in the unit 20 has not been illegally replaced, the serial number 22 displayed on the board 21 in the unit 20 is stored in the case 23 when the unit 20 is assembled. It should be the same as the serial number of board 21. Therefore, if the serial number written as encryption key information on the RFID label 30 is decrypted, The converted serial number matches the serial number 22 of the unit 20 input to the operation unit 11 in step S13. On the other hand, if the board 21 in the unit 20 is illegally replaced, the serial number 22 displayed on the board 21 in the unit 20 is the board 21 stored in the case 23 when the unit 20 is assembled. This is different from the serial number. Therefore, even when the RFID label 30 is peeled cleanly from the unit 20 and the RFID label 30 is attached to the unit 20 again, the serial number written as encryption key information on the RFID label 30 is decrypted. If it is entered, the decrypted serial number does not match the serial number input to the operation unit 11 in step S13.

[0050] In this way, when the unit 20 in which the substrate 21 is stored in the case 23 is sealed with the RFID label 30, the serial number of the unit 20 displayed on the substrate 21 is displayed using the information processing terminal 10. 22 and the UID of the RFID label 30 are encrypted and written to the RFID label 30 as encrypted information, and then the information on the RFID label 30 is read using the information processing terminal 10. The RFID label 30 from the unit 20 is decrypted by comparing the serial number and the UID of the RFID label 30 with the serial number of the unit 20 and the UID of the RFID label 30 displayed on the board 21. It is possible to detect whether or not the unit 20 has been tampered with. That is, the association between the unit 20 and the RFID label 30 can be managed only by the information processing terminal 10 without constructing a database or a communication infrastructure for accessing the database.

[0051] (Second Embodiment)

FIG. 5a is a diagram showing an overall configuration of the second embodiment of the article management system of the present invention. FIG. 5b is a block diagram illustrating a configuration of the information processing terminal 110 illustrated in FIG. 5a.

In this embodiment, as shown in FIG. 5a, illegal disassembly of the units 20a to 20c, in which the substrates 21a to 21c are housed in the cases 23a to 23c, respectively, and a gaming table 40 to which the units 20a to 20c are attached. To detect unauthorized replacement of units 20a to 20d. RFID labels 30a to 30c, which are information recording media, are affixed to the joints of the cases 23a to 23c, respectively, and bar code information 41, which is identification information unique to the game stand 40, is printed or bar code labels on the game stand 40. Is displayed. This RFID label 30a ~ 30c and unit By managing the association between 20a to 20c and gaming table 40 using information processing terminal 110, unauthorized disassembly of units 20a to 20c and unauthorized replacement of units 20a to 20d with respect to gaming table 40 are detected. .

[0053] Each of the units 20a to 20c is similar to the unit 20 shown in the first embodiment, and the substrates 21a to 21c are housed in cases 23a to 23c that can be opened at the joints, and the joints are RFID labels 30a to 30c are attached as sealing seals in the closed state. In addition, serial numbers 22a to 22c serving as identification information unique to the units 20a to 20c are displayed on the boards 21a to 21c.

As shown in FIG. 5b, the information processing terminal 110 is different from the information processing terminal 10 shown in the first embodiment only in that a barcode reading unit 19 is provided.

The bar code reading unit 19 reads the bar code information 41 displayed on the game table 40.

[0056] The following is an article management method using the article management system configured as described above, and a method for detecting unauthorized disassembly of units 20a to 20c and unauthorized replacement of units 20a to 20d with respect to the gaming table 40. explain.

First, a process when assembling the units 20a to 20c and the game table 40 will be described.

FIG. 6 is a flowchart for explaining processing when assembling the units 20a to 20c and the game table 40 in the article management system shown in FIGS. 5a and 5b.

[0059] The unit 20a is assembled by housing the substrate 21a in the case 23a. At that time, in step S 101, the serial number 22 a of the unit 20 a displayed on the substrate 21 a is input to the operation unit 11 of the information processing terminal 110. The serial number 22a is unique identification information given to each of the units 20a to 20c, and is displayed in a state of being visible on the substrate 21a.

[0060] Next, the joint portion of the case 23a containing the substrate 21a is closed, the RFID label 30a is attached to the joint portion, and the case 23a is sealed. In step S102, the information processing terminal 110 Is used to read the UID of RFID label 30a. At this time, if the information processing terminal 110 is put on the RFID label 30a, the information reading unit 12 of the information processing terminal 110 reads the UID written on the RFID label 30a in a non-contact state. Na The

[0061] Next, in step S103, the barcode information 41 displayed on the gaming table 40 to which the unit 20a to which the RFID label 30a is attached is attached is read using the information processing terminal 110. Bar code information 41 displayed on the gaming table 40 is a bar code representation of the serial number of the gaming table 40. Therefore, when the barcode reading unit 19 of the information processing terminal 110 reads the barcode information 41 displayed on the gaming table 40, the read barcode information 41 is recognized as a serial number.

[0062] The serial number 22a of the unit 20a input to the operation unit 11, the UID of the RFID label 30a read by the information reading unit 12, and the bar code information 41 is read by the bar code reading unit 19. The serial number of the gaming table 40 recognized in this way is given to the encryption key section 13. In step S104, the serial number 22a of the unit 20a input to the operation unit 11, the UID of the RFID label 30a read by the information reading unit 12, and the bar code information 41 by the bar code reading unit 19. The encryption unit 13 also encrypts the serial number of the gaming table 40 that has been read and recognized as Note that the encryption in the encryption unit 13 is performed using the encryption key acquired by the key acquisition unit 16 in the same manner as described in the first embodiment.

[0063] After that, when the information processing terminal 110 is put on the RFID label 30a, in step S105, the information writing section 14 of the information processing terminal 110 transmits the information given from the encryption section 13 to the encryption. It is written to RFID label 30a as non-contact information as key information. Note that the encryption information is written in a storage area different from the storage area in which the UID of the RFID label 30a is written, as shown in FIG.

[0064] The above-described processing is performed for all of the units 20a to 20c.

[0065] When the units 20a to 20c and the gaming table 40 are assembled in this way, the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c are used using the information processing terminal 110. The bar code information 41 displayed on the gaming table 40 and the UIDs of the RFID labels 30a to 30c are encrypted together and written into the RFID labels 30a to 30c as encrypted information.

[0066] Next, unauthorized disassembly of the units 20a to 20c and the units 20a to 20c with respect to the game table 40 The process for confirming the unauthorized replacement of will be explained.

[0067] FIG. 7 illustrates a process for confirming the unauthorized disassembly of the units 20a to 20c and the unauthorized replacement of the units 20a to 20c with respect to the game table 40 in the article management system illustrated in FIGS. 5a and 5b. It is a flowchart for.

[0068] When the unauthorized disassembly of the units 20a to 20c and the unauthorized replacement of the units 20a to 20c with respect to the gaming table 40 are confirmed, first, when the information processing terminal 110 is put on the RFID label 30a, in step S111, the information The information reading unit 12 of the processing terminal 110 reads the encryption key information and UID written in the RFID label 3 Oa in a non-contact state.

[0069] The encrypted information read from the RFID label 30a by the information reading unit 12 is provided to the decryption unit 15 of the information processing terminal 110. Then, in step S112, the encryption key information read from the RFID label 30a by the information reading unit 12 is decrypted by the decryption key unit 15. Note that the decryption key information is decrypted in the decryption key unit 15 by using the decryption key acquired by the key acquisition unit 16 in the same manner as described in the first embodiment.

[0070] When the decryption unit 15 decrypts the encryption key information read from the RFID label 30a, the serial number 22a of the unit 20a, the UID of the RFID label 30a, and the bar code information of the gaming table 40 The serial number displayed as 41 is given to the verification unit 17.

Next, in step S113, the serial number 22a of the unit 20a displayed on the board 21a is input to the operation unit 11 of the information processing terminal 110. In step S114, the barcode reading unit 19 of the information processing terminal 110 reads the barcode information 41 displayed on the gaming table 40.

[0072] The serial number 22a of the unit 20a input to the operation unit 11, the UID read from the RFID label 30a by the information reading unit 12 in step S111, and the barcode information by the barcode reading unit 19 The serial number of the gaming table 40 read and recognized as 41 is given to the verification unit 17. In step S115, the serial number of the unit given from the decryption key unit 15, the UID of the RFID label, and the serial number of the gaming table, and the serial number of the unit given from the operation unit 11 and the information reading unit 12, The collation unit 17 collates the UID of the RFID label and the serial number of the game machine.

[0073] Thereafter, in step S116, the collation result in collation unit 17 is given to output unit 18. Is displayed and output. The collation result display output includes, for example, the serial number of the unit given from the decryption unit 15, the UID of the RFID label, and the serial number of the gaming table, and the unit given from the operation unit 11 and the information reading unit 12. If the serial number, the UID of the RFID label, and the serial number of the game machine match each other, it is displayed that both match, and the serial number of the unit to which the decryption unit 15 is given, RFID When the UID of the label and the serial number of the gaming table match the serial number of the unit given from the operation unit 11 and the information reading unit 12, the UID of the RFID label, and the serial number of the gaming table It is conceivable that both will be displayed if they match. Also, the serial number of the unit given from the decryption unit 15, the UID of the RFID label, and the serial number of the gaming table, the serial number of the unit given from the operation unit 11 and the information reading unit 12, and the RFID label The UID and the serial number of the game machine may be displayed on the output unit 18.

[0074] The above-described processing is performed for all of the units 20a to 20c.

[0075] Here, if the units 20a to 20c are illegally disassembled !, the units 20a to 20c are the same as the RFID labels 30a to 30c attached when the units 20a to 20c are assembled. RFID labels 30a-30c should be affixed. Therefore, when the UID written as encryption key information in the RFID labels 30a to 30c is decrypted, the decrypted UID is read from the RFID labels 30a to 30c in step SI11. This will match the UIDs of 30a-30c. Similarly, when the serial number of the unit written as the encryption key information on the RFID labels 30a to 30c is decrypted, the decrypted serial number is input to the operation unit 11 in step S113. Will match the serial numbers 22a-22c of the units 20a-20c. On the other hand, when the units 20a to 20c are illegally disassembled, the RFID labels 30a to 30c different from the RFID labels 30a to 30c attached when the units 20a to 20c are assembled are affixed to the units 20a to 20c. It is worn. Therefore, even if the serial numbers 22a to 22c of the units 20a to 20c are encrypted and written to the RFID labels 30a to 30c newly attached to the units 20a to 20c in the same manner as described above, the RFID labels If the UID written as encryption information in 30a-30c is decrypted, the decrypted UID is RFID label 30a-3 in step S111. The RFID label 30a-30c read from Oc will not match the UID.

[0076] When the boards 21a to 21c in the units 20a to 20c are not illegally replaced, the serial numbers 22a to 22c displayed on the boards 21a to 21c in the units 20a to 20c are the units 20a to 20c. Should be the same as the serial number of the boards 21a-21c housed in the cases 23a-23c. Therefore, when the serial number of the unit written as the encryption key information on the RFID labels 30a to 30c is decrypted, the decrypted serial number is stored in the unit 20a input to the operation unit 11 in step S113. It will match the serial number 22a-22c of ~ 20c. On the other hand, if the boards 21a to 21c in the units 20a to 20c are illegally replaced, the serial numbers 22a to 22c displayed on the boards 21a to 21c in the units 20a to 20c are assembled by the units 20a to 20c. When this is done, the serial numbers of the boards 21a-21c housed in the cases 23a-23c will be different. Therefore, even if the RFID labels 30a to 30c are peeled cleanly from the units 20a to 20c and the R FID labels 30a to 30c are affixed to the units 20a to 20c again, the RFID labels 30a to 30c are encrypted. When the serial number written as information is decrypted, the decrypted serial number does not match the serial number input to the operation unit 11 in step S113.

[0077] In this way, when the units 20a to 20c in which the substrates 21a to 21c are accommodated in the cases 23a to 23c are sealed with the RFID labels 30a to 30c, the information processing terminal 110 is used to seal the substrates 21a to 21c. The serial numbers 22a to 22c of the units 20a to 20c and the UIDs of the RFID labels 30a to 30c are encrypted together and written to the RFID labels 30a to 30c as encrypted information. Is used to read and decrypt the encryption key information written in the RFID labels 30a to 30c, decrypt the serial number, the UID of the RFID labels 30a to 30c, and the units displayed on the boards 21a to 21c. By checking the serial number of 20a to 2 Oc and the UID of RFID label 30a to 30c, it can be confirmed whether the RFID label 30a to 30c has been peeled off from the unit 20a to 20c and the unit 20a to 20c has been illegally disassembled. Can be detected. In other words, the correspondence between the units 20a to 20c and the RFID labels 30a to 30c can be managed only by the information processing terminal 110 without constructing a communication infrastructure for accessing the database and the database. The

[0078] In addition, when the units 20a to 20c are not illegally replaced with respect to the gaming table 40, the RFID units 20a to 20c occupied by the shells 20a to 20c have the units 20a to 20c. The serial number of the attached gaming base 40 should be written as encrypted information together with the serial number of units 20a-20c and the UID of RFID labels 30a-30c. Therefore, when the encryption key information written in the RFID labels 30a to 30c is decrypted, the decrypted information includes the serial number of the units 20a to 20c input in step S113 and the step SI 11 This includes the UID read from the RFID labels 30a to 30c and the serial number read and recognized as the barcode information 41 at step S114. On the other hand, if the units 20a to 20c are illegally replaced for the gaming table 40, the serial numbers 22a to 22c of the units 20a to 20c and the serial number of the gaming table 40 are combined with the UIDs of the RFID labels 30a to 30c. It is encrypted and not written on the RFID labels 30a-30c. Therefore, when the decryption information written to the RFID labels 30a to 30c is decrypted, the decrypted information includes the serial numbers of the units 20a to 20c input in step S113 and the step S111. RFID label 30a-30c The UID from which the force was read and the serial number that was read and recognized as bar code information 41 in step SI 14 are included in correspondence! / Wow! /

[0079] In this way, when the units 20a to 20c are attached to the gaming table 40, the information processing terminal 110 is used to play the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c. The serial number based on the barcode information 41 of the table 40 is encrypted together with the UID of the RFID label 30a to 30c and written to the RFID label 30a to 30c as encrypted information, and then the information processing terminal 110 is used to Reads and decrypts the encrypted information written on the labels 30a to 30c, serializes the decrypted information, the serial numbers of the units 20a to 20c displayed on the boards 21a to 21c, and the barcode information 41 of the gaming table 40 By checking the number, it is possible to detect whether the units 20a to 20c have been illegally replaced with respect to the gaming table 40. That is, the association between the units 20a to 20c and the game machine 40 can be managed only by the information processing terminal 110 that does not construct a database or a communication infrastructure for accessing the database. [0080] In this embodiment, the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c and the bar code information 41 of the game table 40 and the UIDs of the RFID labels 30a to 30c are used. And is written to the RFID labels 30a to 30c as encrypted information and then written to the RFID labels 30a to 30c using the information processing terminal 110. By reading the information and decrypting it, by comparing the decrypted information with the serial number of the units 20a-20c displayed on the boards 21a-21c and the serial number of the bar code information 41 of the game table 40 , The unit 20a to 20c is illegally replaced with respect to the game table 40! /, It is detected that the serial number 22a to the unit 20a to 20c displayed on the boards 21a to 21c is detected. Barcode information 41 of all 22c and game console 4 0 The serial number and all the UIDs of the RFID labels 30a to 30c are encrypted together and written as encrypted information to at least one of the RFID labels 30a to 30c. This information is decrypted and decrypted. By checking the serial number of the units 20a to 20c displayed on the boards 21a to 21c and the serial number based on the bar code information 41 of the gaming table 40, the unit 20a to the gaming table 40 is checked. It may be configured to detect whether 20c is illegally replaced.

[0081] In the two embodiments described above, the voice corresponding to the matching result in the force matching unit 17 described as an example in which the matching result in the matching unit 17 is displayed and output on the output unit 18 is output. It is also possible to output.

In addition, only the information decoded by the decryption unit 15 is displayed and output on the output unit 18 instead of displaying the collation result in the collation unit 17 on the output unit 18. It is also conceivable to visually check the information displayed on the board and the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c.
