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the amount is collected from the electronic coupon information, the wireless line is disconnected and the amount is withdrawn while taking out the product.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, only a product can be selected by establishing a wireless line with the vending machine, and the product is provided after the amount is deducted (see Patent Document 2).

However, for example, it is not possible to prevent fraud that can be restored and reused once it has been used for an electronic coupon that includes the provision of one product or one service. It is desired. In order to respond to such demands in electronic coupon transactions, management using illegal use information called negatives can be considered, but this negative has a problem of increasing over time.

  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.

  FIG. 6 shows a configuration diagram of the mobile phone 100. The cellular phone 100 has a configuration in which a display unit 11, an input unit 12 such as various keys, a telephone function unit 13, and a memory 14 are connected to a CPU 10 that controls each unit. A radio communication unit 18 is connected to the telephone function unit 13, and voice input from a microphone provided in the telephone function unit 13 is transmitted as a voice signal from the radio communication unit 18. In addition, a signal related to a call coming from the wireless communication unit 18 is down-converted into an audio signal, sent to the telephone function unit 13, and output as a voice from a speaker.

  The CPU 10 implements various functions such as an electronic mail function and an Internet communication function by application programs provided in the memory 14. Further, the application program AP1 relating to the download described above with reference to FIG. 2 is also stored in the memory 14, and by executing this, processing necessary for the electronic coupon transaction is performed.

  Further, the memory 14 is provided with a storage area 15. The storage area 15 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 storage area 15, 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, followed by “serial”, and then chip identification information “IDm” which is the chip manufacturing number information for electronic money. Is placed next, "Life", which is information for minimizing the amount of negative information retained and the time until the electronic coupon needs to be regenerated, is issued, and the electronic coupon is issued “Issuing place ID”, which is information for identifying a location, is arranged, followed by “checksum code method”, which is information indicating a checksum method, and then all data before encryption (broken line) "Checksum" that is a hash value created for data (including plaintext data that is not enclosed by Is a tio down information "(those to be encrypted out of) the application information" 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 the encryption key and a key serial code is arranged, and next is information for minimizing the amount of negative information retained. “Lifetime”, which is time information until the electronic coupon needs to be regenerated, is placed, and “App information (of which should be in plaintext)” consisting of information about products and deadlines is placed . 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 storage area 15 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.

  The memory 25 is provided with log storage means 26 for storing the unique number information (in this embodiment, information consisting of lot ID and serial) of the electronic coupon used in the vending machine 200. Further, the memory 25 is provided with negative storage means 27 for storing the unique number information of the illegally used electronic coupon sent from the electronic coupon issuing server 300 (in this embodiment, information consisting of lot ID and serial number). Yes.

  The CPU 20 includes a comparison unit 31, a clock unit 32, a second detection unit 33, a first detection unit 34, and a control unit 35. The clock means 32 generates time information including at least the current date.

  The comparison unit 31 compares the unique number information read from the storage area 15 of the mobile phone 100 with the unique number information stored in the negative storage unit 27.

  When the electronic coupon is used, the second detection means 33 detects whether the electronic coupon is within the expiration date based on the expiration date information of the electronic coupon and the time information by the clock means. When the electronic coupon is used, the first detection means 34 detects whether the electronic coupon is within the lifetime based on the lifetime information of the electronic coupon and the time information by the clock means.

The control unit 35 controls provision / rejection of service or product according to the comparison result by the comparison unit 31 and the detection result by the second and first detection units 33 and 34, and controls the product provision unit 21. . The CPU 20 further performs a detection process using the checksum using the checksum included in the electronic coupon information of FIG. When fraud or the like is detected by the detection process using the checksum, the control unit 35 controls the refusal to provide the product and controls the product providing 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 storage means 15 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 displays the data of the reader / writer 23 in the flowchart of FIG. The reading is monitored (S11), the data branched to YES and read by the reader / writer 23 is decrypted using the public key corresponding to the secret key used in the electronic coupon issuing server 300 (S12), and handled It is detected whether it is an electronic coupon according to the application information, lot ID, or serial number (S13).

  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, based on the expiration date information included in the application information of the electronic coupon and the time information by the clock means 32, it is detected whether the electronic coupon is within the expiration date (S19). Whether it is OK) is determined (S20). If it becomes OK in step S20, the process proceeds to step S21.

  In step 21, it is detected whether the electronic coupon is within the lifetime based on the lifetime information of the electronic coupon and the time information by the clock means 32 (S21), and it is determined whether the lifetime is within the lifetime (OK) (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.

  If the process branches to NO in steps S14, S16, S18, S20, and S22, the process proceeds to step S24, where the CPU 20 controls the product providing unit 21 to cancel the product non-delivery, which is a process of stopping discharging the product and the like. Since it performs (S24), in the case of fraud, an appropriate electronic coupon transaction is realized without providing a product (service).

  Here, the meaning of the lifetime information will be described. The lifetime information is refresh time information until the electronic coupon needs to be regenerated. For example, as shown in FIG. 10A, when the serial number constituting the unique number information of the electronic coupon KP is 011, the issue date is January 10, and the expiration date L is April 30, the lifetime N is 2 months. The lifetime N may be longer than the expiration date, but is set shorter than the expiration date so that several regenerations (refreshes) are required within the normal expiration date.

  In FIG. 10 (a), the last day by the lifetime N of a genuine and unused electronic coupon (serial: 011) KP is March 10, and if regeneration is not performed after March 11, for example, Even if the use is attempted in the period t1 in FIG. 10 (a), it is not possible to branch to NO in steps S21 and S22 in FIG. Therefore, for example, the user performs a predetermined operation using the input unit 22 to start the application program AP1, and requests the electronic coupon issue server 300 to regenerate the electronic coupon (serial: 011). As described above, the mobile phone 100 receives the regeneration unit for requesting the regeneration of the electronic coupon from the issuer of the electronic coupon, and the regeneration unit receives the predetermined operation from the operation unit. Activation control means for performing activation control so as to be requested to the electronic coupon issue server 300 which is the issuer of

  In response to this request, the electronic coupon issue server 300 downloads the electronic coupon information of a new electronic coupon (serial: 011) KP2 whose lifetime N is 2 months from this time. The downloaded electronic coupon information is written into the storage area 15 by the writing means 17. When the electronic coupon (serial: 011) KP2 is regenerated on March 18, the last day of the lifetime N is May 18, but the last day of the expiration date L is April 30. Even if an attempt is made to use the electronic coupon (serial: 011) KP2 during the period t2 exceeding April 30, it is not possible to branch off to NO through steps S19 and S20 in FIG. .

  On the other hand, when there is an illegal electronic coupon (serial: 011) KPC shown in FIG. 10 (b) obtained by illegally copying the electronic coupon (serial: 011) KP shown in FIG. For example, it is assumed that negative information with serial number 011 is sent from the electronic coupon issue server 300 on February 6. Even if an attempt is made to use the fraudulent electronic coupon (serial: 011) KPC after February 6, the vending machine 200 stores the negative information (serial: 011) in the negative storage means 27. It is not possible to branch to NO in steps S17 and S18 and receive provision of goods and the like.

  Further, the last day of the fraudulent electronic coupon (serial: 011) KPC by the service life N is March 10, and even if the vending machine 200 tries to use it after March 11, the vending machine 200 performs the steps of FIG. It is not possible to branch to NO through S21 and S22 and receive a product or the like. Even if a mobile phone having an unauthorized electronic coupon (serial: 011) KPC requests the electronic coupon issuing server 300 to regenerate, it is rejected based on the negative information, and therefore, refreshing is not performed. Therefore, after March 11, the vending machine 200 can delete the negative information (serial: 011) from the negative storage means 27, and only needs to hold the negative information (serial: 011) for the period t3. Become.

  By managing the electronic coupon information according to the lifetime and the expiration date in this way, it is possible to use the regular electronic coupon until the expiration date, and to invalidate the illegal electronic coupon without using the negative information after the lifetime. It is possible to reduce the amount of negative information held in the vending machine and perform an appropriate electronic coupon transaction.
