Description

  The present invention relates to an electronic coupon for preventing a transaction by an illegal electronic coupon when the vending machine is made to read the electronic coupon information from the wireless communication terminal that has obtained the electronic coupon and the provision of goods or services is received from the vending machine. The present invention relates to a transaction system, a vending machine used in the electronic coupon transaction system, and a program for operating the vending machine.

  As this type of conventional system, an electronic coupon service device, a receiving terminal, and a user terminal are configured to be communicable at any time, and a winning result (validity) can be determined in real time. (See Patent Document 1). However, this system is based on the premise that the electronic coupon service device, the receiving terminal and the user terminal can communicate at any time, and is basically isolated like a vending machine. It is not suitable for systems where effectiveness must be determined independently.

  On the other hand, after the wireless line with the vending machine is established and the product can be provided, before the amount is collected from the electronic coupon information, the wireless line is disconnected and the amount is withdrawn while taking out the product. Something that prevents such fraud has been devised. In this system, depending on the establishment of a wireless line with a vending machine, only product selection is possible, and after the amount has been deducted, the product is provided (see Patent Document 2).

However, for example, for electronic coupons that include the provision of one product or one service, it is not possible to prevent fraud that can be revived on its own terminal or another terminal while using it once. Improvement is desired.

  Embodiments of an electronic coupon transaction system, a vending machine, and a program according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference numerals and redundant description is omitted. In FIG. 1, the block diagram of the Example of the electronic coupon transaction system which concerns on this invention is shown. This system includes an electronic coupon issue request server 400, an electronic coupon issue server 300, a plurality of automatic vending machines 200, and a mobile phone 100 that is usually a plurality of wireless communication terminals. Here, although the electronic coupon issue request server 400 and the electronic coupon issue server 300 are provided, the electronic coupon issue server 300 may be configured only by the electronic coupon issue server 300.

  For example, it is assumed that there is a contract for obtaining an electronic coupon providing one product CC on the condition that it becomes a TR member of the store TR, and the user of the mobile phone 100 becomes a TR member of the store TR. Therefore, as shown in FIG. 2, the user uses the mobile phone 100 to access the electronic coupon issue server 300, and receives the download of the application program AP1 that enables the mobile phone 100 to process transactions using the electronic coupon (SS11). . At this time, the downloaded application program AP1 converts the UID, which is an ID unique to the mobile phone 100, and the chip identification information IDm, which is chip manufacturing number information for electronic money including the electronic coupon, from the mobile phone 100 to the electronic coupon. It is automatically transmitted to the issuing server 300 (SS12), and the member number A of the TR member of the store TR is received from the electronic coupon issuing server 300 (SS13). The membership number A is held in the mobile phone 100 and can be displayed on the display unit 11 as necessary.

  Next, as shown in FIG. 3, in order to obtain an electronic coupon, it accesses the electronic coupon issue request server 400 of the store TR and notifies that it has become a TR member of the store TR (SS14). In response to the membership number request returned (SS15), the user inputs and transmits the membership number A (SS16) and receives a confirmation notification (SS17).

  Next, as shown in FIG. 4, the electronic coupon issue request server 400 transmits a request for issuing an electronic coupon to the member of the member number A to the electronic coupon issue server 300 (SS21). This electronic coupon issue request includes the lot ID of the electronic coupon, the store name (store TR here), and the member number A.

  The electronic coupon issue server 300 includes a lot management master file F1, a coupon member master file F2, an electronic coupon master file F3, and a used master file F4 shown in FIG. Upon receiving the electronic coupon issue request, the electronic coupon issue server 300 issues an electronic coupon and decrements the inventory corresponding to the store TR in the lot management master file F1 from “300” to “299” (P1 in FIG. 5). Various information related to the electronic coupon issued to the electronic coupon master file F3 is registered, and the status is set to “deposit”. Registration for the coupon member master file F2 is performed after the processing shown in FIG. 2, and registration is not performed in the used master file F4 when the electronic coupon is issued. In the electronic coupon master file F3, the relationship between the status type and the state transition in the electronic coupon is appended.

  As shown in FIG. 4, the electronic coupon issue server 300 downloads electronic coupon information related to the issued electronic coupon to the mobile phone 100 (SS22), and receives a successful download notification returned in response to this (SS23). ), The status of the corresponding entry of the electronic coupon master file F3 is changed to download DL (SS24).

  The electronic coupon handled here can be deposited from the mobile phone 100 to the electronic coupon issuing server 300, or can be transferred to a TR member having another registration number (for example, B) of the store TR. By sending a deposit request from the mobile phone 100 to the electronic coupon issue server 300, the status of the electronic coupon master file F3 is changed to “deposit”, and a deposit request on the premise of transfer from the mobile phone 100 to the electronic coupon issue server 300 and By sending a transfer destination member number (for example, B) and a password, the status of the electronic coupon master file F3 is changed to “deposit” on the premise of transfer, and the password is set in security information, for example. As shown in FIG. 4, the member with the member number B can receive a download by transfer by sending a transfer request and the password set by the member with the member number A from the mobile phone 100B to the electronic coupon issuing server 300. In this case, the status of the electronic coupon master file F3 is changed to download DL, and the owner TR member number is changed from “A” to “B” (P2 in FIG. 5). Of course, the chip identification information IDm included in the transferred and downloaded electronic coupon is changed to that of the mobile phone 100B.

The first storage area 15 is an area in which chip identification information IDm, which is chip manufacturing number information for electronic money provided in at least the mobile phone (wireless communication terminal) 100, is stored. The second storage area 16 is an area in which the electronic coupon information downloaded in the already explained SS22 of FIG. 4 is stored. In order to write the downloaded electronic coupon information in the second storage area 16, the CPU 10 is provided with writing means 17.

  The coupon information is configured as shown in FIG. A description will be given from the upper stage to the lower stage in the figure. In the top level, the “lot ID” of the product provided by the electronic coupon is arranged, then “serial” is arranged, then the chip manufacturing number information “IDm” for electronic money is arranged, and the next “Life”, which is information for minimizing the amount of negative information held, is placed, “Issuing place ID”, which is information for identifying the issuing place of the electronic coupon, etc. is placed next, and then checked “Checksum code method”, which is information indicating the sum method, is arranged, and then “checksum” is a hash value created for all the data before encryption (including plaintext area data not enclosed by broken lines) ”Is arranged, and“ application information (of which to be encrypted) ”composed of information on products and deadlines is arranged. The information arranged in the encryption area EA of FIG. 7 described above is encrypted with the secret key in the electronic coupon issue server 300. The public key corresponding to this secret key is distributed from the electronic coupon issuing server 300 to the vending machine 200, and the vending machine 200 holds this public key.

  In the next stage of the encryption area EA, a “key code” composed of an algorithm code relating to an encryption key and a key serial code is arranged, and next is information for minimizing the amount of negative information retained. “Lifetime” is arranged, and “application information (of which should be plaintext)”, which is application information composed of information on products and deadlines, is arranged. The information in the non-encrypted area is information used by the mobile phone (wireless communication terminal) 100. Also, the coupon information in FIG. 7 is erased by the mobile phone (wireless communication terminal) 100 by using or transferring the coupon.

  FIG. 8 shows a configuration diagram of the vending machine 200. The vending machine 200 is centered on a CPU 20 that controls each unit, and a product providing unit 21 that discharges the product to the outlet, an input unit 22 including a product selection button, a reader / writer 23, a wired communication unit 24, a memory 25 is connected.

  The reader / writer 23 reads information from the first and second storage areas 15 and 16 of the mobile phone 100. The wired communication unit 24 is for transmitting and receiving information to and from the electronic coupon issue server 300 via a wired line. The vending machine 200 is basically an isolated device, and transmission / reception of information using the wired communication unit 24 is performed once a day, for example, and log information is transmitted to the electronic coupon issuing server 300 to issue an electronic coupon. Negative information is received from the server 300.

  In the memory 25, log storage means 26 for storing, as a log, unique number information (in this embodiment, information consisting of lot ID and serial) of an electronic coupon once used in the vending machine 200, and an electronic coupon issuing server Negative storage means 27 is provided for storing unique number information (in this embodiment, information consisting of a lot ID and a serial number) of an electronic coupon illegally used sent from 300.

  The CPU 20 includes log writing means 31, first comparison means 32, second comparison means 33, and control means 34. The log writing unit 31 writes the unique number information read by the reader / writer 23 from the first storage area 15 of the mobile phone 100 to the log storage unit 26 when an electronic coupon is used.

  The first comparison means 32 includes the chip identification information IDm read from the first storage area 15 of the mobile phone 100 and the chip identification information and IDm included in the coupon information read from the second storage area 16 of the mobile phone 100. Are compared. The second comparison unit 33 compares whether or not the unique number information read from the second storage area 16 of the mobile phone 100 matches the unique number information stored in the log storage unit 26.

  The control means 34 controls service / product provision / rejection according to the comparison results of the first and second comparison means 32, 33, and controls the product provision unit 21. The CPU 20 further performs detection processing using a checksum using the checksum included in the electronic coupon information in FIG. 7 and performs a check using the negative information stored in the negative storage means 27 of the memory 25. In the case where fraud or the like is detected by a checksum detection process or a check using negative information, the control unit 34 controls the product provision refusal and controls the product provision unit 21.

  The CPU 20 of the vending machine 200 configured as described above functions as each unit of FIG. 8 by executing a program corresponding to the flowchart shown in FIG. 9, and the operation will be described based on this flowchart. Regarding the pair of steps S15 and S16, the pair of steps S17 and S18, the pair of steps S19 and S20, and the pair of steps S21 and S22 in this flowchart, these pairs may be arranged in any order. FIG. 9 shows an example.

  In a state where the electronic coupon information is written in the second storage area 16 by the writing means 17, when the mobile phone 100 is held over the position of the reader / writer 23 of the vending machine 200, the CPU 20 reads the reader / writer in the flowchart of FIG. 23 is monitored (S11), and the process branches to YES and the electronic coupon information read by the reader / writer 23 is decrypted using the public key corresponding to the private key used in the electronic coupon issuing server 300 ( S12), it is detected using application information, lot ID, serial number, etc. whether it is an electronic coupon related to the handling object (S13). The reader / writer 23 reads the chip identification information IDm from the first storage area 15 in the above.

  As a result of the detection in step S13, it is determined whether the electronic coupon is a handling target electronic coupon (S14). If it is a handling target electronic coupon, all data of the electronic coupon information (data in a plain text area not surrounded by a broken line is obtained). A hash value is created for the data including the checksum, and a checksum process including comparison with the checksum of the electronic coupon information is performed (S15), and it is determined whether they match (is OK) (S16). If it becomes OK in step S16, the process proceeds to step S17.

  In step S17, the unique number information composed of the lot ID and the serial included in the electronic coupon information, the unique number information composed of the lot ID and the serial of the negative storage means 27 (which is illegally used), A comparison is made (S17), and it is determined whether they are inconsistent (OK) (S18). If it becomes OK in step S18, the process proceeds to step S19.

  In step S19, the reader / writer 23 compares the chip identification information IDm from the first storage area 15 of the mobile phone 100 with the chip identification information IDm included in the electronic coupon information (S19). (OK) is determined (S20). If it becomes OK in step S20, the process proceeds to step S21.

  Steps S19 and S20 have the following significance. That is, the chip identification information IDm is stored in the first storage area 15 of the mobile phone 100 from the beginning, and when receiving the download of the application program AP1 (SS11), it is transmitted to the electronic coupon issuing server 300, Based on this, it is included in the electronic coupon information. Therefore, the chip identification information IDm in the first storage area 15 of the mobile phone 100 should match the chip identification information IDm included in the electronic coupon information. Therefore, the detection using the chip identification information IDm can prevent the electronic coupon from being used when it is illegally copied to another mobile phone 100B.

  In step S21, the unique number information (one used in the vending machine 200 once) composed of the lot ID and serial stored in the log storage means 26, and the lot ID included in the electronic coupon information. Is compared with the unique number information composed of the serial number (S21), and it is determined whether or not they match (S22). If it becomes OK in step S22, the process proceeds to step S23.

  In step S23, the CPU 20 logs the unique number information composed of the lot ID and the serial included in the electronic coupon, and the provision of the merchandise, which is a process such as discharging the merchandise by controlling the merchandise providing unit 21. Writing to the storage means 26 (S23), the process is terminated.

  Steps S21 and S22 have the following significance. That is, the unique number information including the lot ID and the serial number once included in the electronic coupon used in the vending machine 200 is written in the log storage unit 26 in step S23. Therefore, in steps S21 and S22, the unique number information composed of the lot ID and the serial stored in the log storage means 26, the unique number information composed of the lot ID and the serial included in the electronic coupon information, The electronic coupons already used in the vending machine 200 cannot be used. Therefore, this process can prevent the electronic voucher 200 from being used when the electronic coupon once used is illegally copied in the mobile phone 100 or another mobile phone 100B.

  Further, when branching to NO in steps S14, S16, S18, S20, and S22, the CPU 20 controls the product providing unit 21 to perform product non-provisioning, which is a process of stopping discharging of the product and the like (S24). Therefore, in the case of fraud, an appropriate electronic coupon transaction is realized without providing a product (service).
