Description

  The present invention relates to a ticket system. In particular, it relates to a ticket system that prevents resale.

  Tickets are used to judge admission at various events such as movies, concerts, and symposiums. In the past, most paper tickets were used, but nowadays, electronic tickets, which are electronic versions of tickets, are also widely used.

  In the case of an electronic ticket, the information corresponding to the ticket is encoded with a one-dimensional code or a two-dimensional code, and the code is sent to the purchaser of the ticket by an appropriate method such as electronic mail. The purchaser can enter the event by reading the code with a code reader installed near the entrance gate of the event.

  On the other hand, high resale of tickets including electronic tickets has become a problem. For this reason, the event organizer takes measures against resale by various methods. However, as the measure against resale is strengthened, the convenience of the ticket purchaser is impaired. There are currently no effective measures that satisfy both parties.

  Further, as an electronic ticket system for preventing resale, there is a system as disclosed in Patent Document 1 below, for example.

JP, 2013-20599, A

  By using the system of Patent Document 1, resale of the electronic ticket can be prevented, but the purchaser of the electronic ticket also needs dedicated application software provided by the event organizer or the issuer of the electronic ticket. Become. Therefore, in order to enter the event, the purchaser must install special application software. Therefore, the purchaser has a heavy burden.

  Further, it is possible to invalidate the ticket by receiving the notification when the ticket is resold, but it is not easy to judge whether the notification is valid.

  In view of the above problems, the present inventor has invented a ticket system capable of suppressing resale with a simple mechanism.

  A first invention is a ticket system using an address of a blockchain, which comprises a ticket issuing processing unit for issuing a ticket identifier using an address of the blockchain and a transaction on the blockchain for an address corresponding to the ticket identifier. And a validity determination processing unit that determines the validity of the ticket identifier.

  By using the ticket identifier that uses the blockchain address, all transactions for the ticket identifier (ticket) are disclosed. Therefore, it is possible to easily monitor the ticket identifier. Therefore, both the person who resells the ticket (primary purchaser) and the person who purchased the resold ticket (secondary purchaser) can recognize that their transaction is public, and thus restrain the resale itself. The effect works.

  In the above invention, the validity determination processing unit is configured like a ticket system that determines the validity of the ticket identifier by determining whether or not there is a transaction on the block chain for the address corresponding to the ticket identifier. be able to.

  The validity of the ticket identifier can be facilitated by determining whether there is a transaction for the corresponding address.

  In the above invention, the ticket system includes a notification processing unit that receives a notification for the ticket identifier from an arbitrary person, and the notification processing unit receives the notification for the ticket identifier, and then receives the notification for the ticket identifier. It can be configured like a ticket system, sending transactions on the blockchain to corresponding addresses.

  The validity of the ticket identifier is determined by the transaction on the blockchain for the corresponding address. When reselling the ticket identifier, information about the ticket (ticket identifier and its code) may be displayed in order to indicate that the ticket identifier is held. Therefore, a person who knows that the ticket identifier (ticket) is being resold may notify the ticket identifier. Then, by sending a transaction to the address corresponding to the ticket identifier, the ticket identifier due to resale can be easily invalidated. In addition, in the blockchain, the relationship between the transaction and the transaction is clearly defined. For this reason, it is possible to easily determine the proximate relationship of a proper report.

  Even if the ticket identifier is not disclosed on the resale site, etc., the person who resells the ticket (primary purchaser) or the person who purchased the resold ticket (secondary purchaser) may make a notification. it can. Therefore, when the primary purchaser resells, the risk of being notified to the secondary purchaser and invalidating the ticket identifier, and when the secondary purchaser purchased from the primary purchaser, the ticket is reported from the primary purchaser There is an inherent risk of the identifier being invalidated. Therefore, the deterrent effect on resale itself will work.

  In the above invention, the ticket system includes a control processing unit that executes a control process corresponding to a determination result in the validity determination processing unit, and the control processing unit has a valid ticket identifier. In this case, a corresponding control process is executed, a transaction on the block chain is sent to the address corresponding to the ticket identifier, and when the ticket identifier is invalid, the corresponding control process is executed. Can be configured as follows.

  When a ticket identifier is used, there is a risk of double use unless the ticket identifier is invalidated. Therefore, by configuring as in the present invention, it is possible to prevent double use.

  In the above invention, the control processing is configured like a ticket system including any one or more of display on a display device regarding validity of the ticket identifier, opening / closing control of an entrance gate, and output of a warning sound. be able to.

  It is preferable to execute the processing according to the present invention according to the result of the validity judgment of the ticket identifier.

  In the above invention, the ticket system includes a notification reward processing unit that executes a process of paying a reward to a person who has issued a notification for the ticket identifier, and the notification reward processing unit is invalidated by the notification. It can be configured like a ticket system that sends a transaction for sending virtual currency equivalent to a reward to an address that sends a transaction for an address corresponding to a ticket identifier.

  By configuring to pay a reward (incentive) for resale of the ticket identifier, it is possible to actively prompt the notification. In addition, when there is resale, multiple people may report resale, in which case it is reasonable to pay the person who reports the earliest. However, in the conventional case, it may not be easy to determine the pro-post relationship of the report. In the present invention, since the ticket identifier is associated with the address on the block chain, the predecessor-successor relationship of the notification can be clearly specified. Moreover, since the whistleblower only uses the address on the blockchain for the transaction, it is not necessary to reveal the attribute information such as name and the like, and the virtual currency equivalent to the reward can be received.

  A seventh aspect of the present invention is a ticket system that uses a blockchain address, and has a ticket issuing processing unit that issues a ticket identifier using a blockchain address.

  By using the ticket identifier that uses the blockchain address, all transactions for the ticket identifier (ticket) are disclosed. Therefore, it is possible to easily monitor the ticket identifier. Therefore, both the person who resells the ticket (primary purchaser) and the person who purchased the resold ticket (secondary purchaser) can recognize that their transaction is public, and thus restrain the resale itself. The effect works.

  An eighth aspect of the present invention is a ticket system using an address of a block chain, the ticket system including a validity determination processing unit that determines the validity of the ticket identifier by a transaction on the block chain for an address corresponding to the ticket identifier. System.

  By judging the validity of the ticket identifier by the transaction on the block chain for the address corresponding to the ticket identifier, the person who tries to use the ticket identifier normally keeps his / her ticket identifier confidential. On the other hand, in the case of resale, since the ticket identifier is passed to at least the person who purchased the resold ticket (secondary purchaser), there is a risk of notification by the second purchaser. In addition, the secondary purchaser also has the risk of being notified by the primary purchaser who knows the ticket identifier. Therefore, the risk of resale itself becomes high, and the deterrent effect on resale works.

  A ninth aspect of the present invention is a ticket system that uses a blockchain address, including a ticket issuing processing unit that generates a blockchain address according to the required number of tickets, and issues a ticket identifier using the generated address. , A ticket information transmission processing unit for transmitting a part or all of ticket information based on the ticket identifier to a recipient of the ticket, and reading a part or all of the ticket information presented by the recipient, the ticket identifier A code reading processing unit that converts the ticket identifier to a valid address, a validity determination processing unit that determines the validity of the ticket identifier by a transaction on the block chain for the address corresponding to the converted ticket identifier, and a determination result of the validity of the ticket identifier. And a control processing unit that executes a control process according to the above and sends a transaction on the block chain to an address corresponding to the ticket identifier when the ticket identifier is valid.

  Even with the configuration of the present invention, it is possible to obtain the same technical effects as those of the first, seventh, and eighth inventions.

  The first invention can be realized by causing a computer to read and execute the program of the present invention. That is, a computer is configured to issue a ticket issuing processing unit that issues a ticket identifier using a block chain address, a validity determination processing unit that determines the validity of the ticket identifier by a transaction on the block chain for an address corresponding to the ticket identifier, It is a ticket program that functions as.

  The seventh invention can be realized by causing a computer to read and execute the program of the present invention. That is, it is a ticket program that causes a computer to function as a ticket issuing processing unit that issues a ticket identifier using a block chain address.

  The eighth invention can be realized by causing a computer to read and execute the program of the present invention. That is, it is a ticket program that causes a computer to function as a validity determination processing unit that determines the validity of the ticket identifier by a transaction on the block chain for the address corresponding to the ticket identifier.

  The ninth invention can be realized by causing a computer to read and execute the program of the present invention. That is, a computer generates a blockchain address according to the required number of tickets, issues a ticket identifier using the generated address, and a part or all of ticket information based on the ticket identifier. Corresponding to the ticket information transmission processing unit for transmitting to the ticket recipient, the code reading processing unit for reading a part or all of the ticket information presented by the recipient and converting it into the ticket identifier, and the converted ticket identifier. A validity determination processing unit that determines the validity of the ticket identifier by a transaction on the block chain for the address, executes control processing according to the determination result of the validity of the ticket identifier, and if the ticket identifier is valid, , A ticket processing program functioning as a control processing unit for sending a transaction on a block chain to an address corresponding to the ticket identifier.

  FIG. 1 shows an example of the overall processing of the ticket system 1 of the present invention, and FIG. 2 is a block diagram showing an example of the processing functions of the ticket system 1. The ticket system 1 uses a ticket issuing system 2, a management system 3, and a field system 4. Further, the ticket purchaser uses a portable communication terminal such as a smartphone or a tablet computer used by the ticket purchaser, or a purchaser terminal 5 such as a personal computer.

  The ticket issuing system 2 is a computer system that issues ticket information, which will be described later, by using the blockchain technology. The management system 3 and the on-site system 4 are systems used by persons who host various events such as movies, concerts, and symposiums. The event organizer includes not only the actual organizer, but also a person who is entrusted by the organizer.

  The ticket issuing system 2, the management system 3, and the field system 4 are realized by using a computer. FIG. 3 schematically shows an example of the hardware configuration of the computer. The computer is capable of inputting information, such as an arithmetic unit 70 such as a CPU that executes arithmetic processing of a program, a storage unit 71 such as a RAM or a hard disk that stores information, a display unit 72 such as a display that displays information. It has an input device 73 such as a keyboard and a mouse, and a communication device 74 for transmitting / receiving the processing result of the arithmetic unit 70 and information stored in the storage device 71 via a network such as the Internet or a LAN.

  When the computer has a touch panel display, the display device 72 and the input device 73 may be integrally configured. The touch panel display is often used in, for example, a portable communication terminal such as a tablet computer or a smartphone, but is not limited thereto.

  The touch panel display is a device in which the functions of the display device 72 and the input device 73 are integrated in that input can be directly performed on the display by a predetermined input device (such as a pen for a touch panel) or a finger.

  The functions of the respective means in the present invention are logically distinct from each other, and may physically or virtually form the same area. The processing order of the processing in each means of the present invention can be appropriately changed. Also, part of the processing can be omitted. Furthermore, the configuration of the system of the present invention can be appropriately changed by executing the process in another system or by distributing it to a plurality of computer systems.

  The ticket issuing system 2 is a computer system that issues ticket information using block chain technology, and includes an event creation acceptance processing unit 20, an issued ticket identifier storage unit 21, a ticket issuance request acceptance processing unit 22, and a ticket issuance processing unit. 23, a ticket information processing unit 24, and a notification processing unit 25.

  Blockchain is a distributed ledger technology. For example, "A protocol or its implementation that uses an unspecified number of nodes, including Byzantine faults, and the probability that the agreement at that point will converge to 0 over time, or its implementation" or "Uses electronic signatures and hash pointers to detect falsification easily. "A technology that realizes high availability and data identity by having a large data structure and storing the data in a large number of nodes distributed over the network" is applicable.

  FIG. 8 schematically shows a block chain. FIG. 8 shows that the block chain has a data structure in which blocks are connected in a chain (in time series). The block contains records of transactions that occurred in the blockchain network, values (hash values, etc.) by a predetermined function such as a hash function that indicates the contents of the block that was created immediately before, and parameters (nonce). ) And. Information other than these may be included. The transaction includes at least the transaction content, and includes, for example, information on remittance (including 0) from the address “A” to the address “B”. A block includes a plurality of transactions, for example, tens to thousands of transactions. If any non-approved transaction is included in a block and a nonce satisfying a predetermined condition is found by a computer (node) that performs a work called mining, the transaction included in the block is approved. To be done. Which unapproved transaction is included in the block is appropriately selected by the computer (node) performing the mining work according to a fee or the like.

  Mining is information included in a block, in the case of FIG. 8, a plurality of unapproved transactions included in a block, a hash value of the immediately preceding block, and a nonce, and a predetermined hash function or the like. This is a task of executing a calculation by a function and searching for a nonce such that the calculation result has a value satisfying a predetermined condition. When SHA256 is used as the hash function, for example, a 64-digit hash value is calculated, and of the 64 digits, for example, the condition from the beginning to the 15th digit is an arbitrary value, for example, zero (0) is satisfied. Explore the nonce.

  The event creation acceptance processing unit 20 accepts an event creation request, which will be described later, from the management system 3 and creates an event. Specifically, in the event creation request, the event name (if there is an event for each date and time, the event name is set so that each can be identified), classification (student, general, child, elderly, disabled, etc.) At least the number of tickets (upper limit of the number of issued tickets) and the number of tickets issued are accepted. The capacity may be set for each category or may be set for the whole. After receiving the event creation request, the event creation acceptance processing unit 20 stores it in the issued ticket identifier storage unit 21 described later. Further, the event creation acceptance processing unit 20 may allocate event identification information for identifying an event and store the above information in the issued ticket identifier storage unit 21 in association with the event identification information. The event name can also be used as the event identification information.

  The issued ticket identifier storage unit 21 stores at least a ticket identifier and a category in association with each event (event identification information). FIG. 9 schematically shows an example of the issued ticket identifier storage unit 21. In FIG. 9, in addition to the ticket identifier and classification, customer identification information, seat information, information indicating the valid / invalid state of the ticket identifier, and the invalidated address of the ticket identifier (address on the block chain) are stored in association with each other. ing. The invalidated address is the address to which the transaction for the ticket identifier has been sent, which is the address of the resale notification (address on the block chain) or the address of the field system 4 (address on the block chain).

  The ticket issuance request reception processing unit 22 receives a ticket issuance request from the management system 3. The ticket issuance request may include at least the number of tickets to be issued and identification information (event name, etc.) of the event, and may also receive the category of the issued ticket, seat information, and customer identification information. The seat information is information indicating a seat or the like in the event of a reserved seat, and the customer identification information is arbitrary identification information used by the event organizer to manage the purchaser of the ticket. The ticket issuance request acceptance processing unit 22 determines whether the number of tickets accepted by the ticket issuance request has reached the event capacity or whether there is duplicate seat information, and if there is any of these, an error is sent to the management system 3. return. If it does not correspond, the processing by the ticket issuing processing unit 23 is executed.

  The ticket issue processing unit 23 generates an address to be used on the block chain and uses the generated address as a ticket identifier. Specifically, a public key is generated from the private key using a public key cryptosystem such as elliptic curve cryptography. Then, using the public key, an address used on the block chain is generated.

  In order to generate an address on the block chain from the public key, first, the public key is first substituted into the hash function SHA256 or the like to obtain the first hash value. Then, the first hash value is substituted into a different hash function RIPEMD160 or the like to obtain the second hash value. A third hash value is obtained by adding a predetermined value, for example, 00 as a header to the head of this hash value, and substituting that value into the hash function SHA256. The fourth hash value is obtained by further substituting the third hash value into the hash function SHA256. Then, the first 4 bytes of the fourth hash value are extracted and added to the last portion as a checksum block (fifth value). Finally, by encoding the fifth value in the Base 58 format, an address used on the block chain can be generated.

  The method of generating the address from the public key is not limited to this. Preferably, the public key is irreversibly derived from the private key and the address is irreversibly derived from the public key.

  The ticket issue processing unit 23 encodes the ticket identifier based on the generated address on the block chain with a predetermined standard such as a one-dimensional code or a two-dimensional code. Further, the ticket identifier is stored in the issued ticket identifier storage unit 21. At this time, the ticket classification, seat information, and customer identification information accepted by the ticket issuance request acceptance processing unit 22 may be stored in association with the ticket identifier. FIG. 10 shows an example of the issued ticket identifier storage unit 21 in this state.

  The private key and the public key used to generate the address used on the block chain form a pair, but the private key may be discarded or may be stored as it is. In general, the address used on the block chain is sufficiently long (for example, the amount of information for 160 bits), and the possibility of collision with other addresses is extremely low.

  When the ticket issuance request acceptance processing unit 22 accepts issuance requests for two tickets, the addresses used on the two block chains are generated, and the respective addresses are used as ticket identifiers. Then, the two addresses (ticket identifiers) are encoded into, for example, a two-dimensional code.

  The ticket information processing unit 24 sends information including the ticket identifier issued by the ticket issuing processing unit 23, the ticket identifier code, or the URL accessible to the ticket identifier code to the management system 3 as ticket information.

  The notification processing unit 25 accepts notification of ticket information from any person. The reception of this notification receives at least the ticket identifier issued by the ticket issuing system 2, and a predetermined transaction (for example, virtual currency) is sent from the address on the block chain of the ticket issuing system 2 to the address that is the ticket identifier that received the notification. A transaction that transfers only "0"). When this transaction is approved on the blockchain, the ticket identifier that received the notification is invalidated.

  When the notification processing unit 25 receives the address on the block chain of the notification person, the notification processing unit 25 associates the address on the block chain of the notification person with the issued ticket identifier storage unit 21 in association with the ticket identifier that received the notification. Remember.

  The management system 3 is a computer system used by an event organizer, and includes an event creation processing section 30, a ticket purchase acceptance processing section 31, a payment processing section 32, a ticket issuance request processing section 33, and a ticket information acceptance processing section 34. It has a ticket information transmission processing unit 35 and a notification reward processing unit 43.

  The event creation processing unit 30 creates an event using the ticket system 1 of the present invention. Specifically, when the management system 3 accepts a predetermined operation, the information about the event, such as the event name, classification, and the number of people, and the event creation request are sent to the ticket issuing system 2.

  The ticket purchase acceptance processing unit 31 accepts an event ticket purchase request from the purchaser terminal 5 used by the purchaser. The ticket purchase process may be the same as a normal ticket purchase process. For example, the event name, date and time, ticket category, price, etc. are displayed on the purchaser terminal 5, and a purchase request for the ticket is accepted from the purchaser terminal 5. At this time, input of information necessary for ticket purchase such as event name, date and time, ticket classification, number of tickets, etc. is accepted. It should be noted that the ticket purchase acceptance processing unit 31 determines whether or not the capacity is exceeded based on the ticket purchase request accepted by the ticket purchase acceptance processing unit 31.

  The settlement processing unit 32 performs settlement processing based on the ticket purchase request accepted by the ticket purchase acceptance processing unit 31 when the capacity is not exceeded. This payment processing can be performed using any payment means such as credit card payment, as in the case of ordinary ticket sales.

  The ticket issuance request processing unit 33 sends a ticket issuance request including at least the number of tickets to the ticket issuing system 2. At this time, if there are a plurality of events, the identification information of the event, the classification when the ticket has a classification, the seat information when there is a reserved seat, and the customer when the information for identifying the customer exists. The identification information may be sent. The seat information is information indicating the seat selected by the purchaser at the time of ticket purchase acceptance processing, and the customer identification information is extracted in advance from a predetermined database or the like, which is identification information used by the event organizer to manage the purchaser. Then, it can be sent to the ticket issuing system 2.

  The ticket information reception processing unit 34 receives the ticket information sent from the ticket issuing system 2 in response to the ticket issuance request in the ticket issuance request processing unit 33.

  The ticket information transmission processing unit 35 sends a part or all of the ticket information received by the ticket information reception processing unit 34 to the purchaser terminal 5. For example, when the ticket information acceptance processing unit 34 accepts a URL that can access the ticket identifier code as the ticket information, the URL is accessed, the ticket identifier code is acquired, and a predetermined message is sent to the purchaser. The ticket identifier code (one-dimensional code or two-dimensional code of the ticket identifier) is sent to a predetermined contact such as an e-mail address or SNS account used by. Further, the code of the ticket identifier may be displayed on the screen of the purchaser terminal 5. Alternatively, the ticket identifier itself may be sent. FIG. 11 shows an example of the notification sent to the purchaser. Although FIG. 11 shows the case where both the ticket identifier and the ticket identifier code are sent to the purchaser, only the ticket identifier or only the ticket identifier code may be sent to the purchaser.

  The on-site system 4 is a computer system installed in an event venue or the like, and corresponds to a computer operated by a person in charge of the event venue, an automatic ticket gate system, or the like. The field system 4 includes a code reading processing unit 40, an effectiveness determination processing unit 41, and a control processing unit 42.

  The code reading processing unit 40 accepts information obtained by reading the code presented by the ticket purchaser when entering the event with a predetermined code reading device. For example, when the code is a two-dimensional code, the information read by the two-dimensional code reading device is accepted. Then, the read code is converted into a ticket identifier.

  The validity determination processing unit 41 confirms whether the ticket identifier converted by the code reading processing unit 40 exists by referring to the issued ticket identifier storage unit 21 in the ticket issuing system 2. Also, after confirming that the ticket identifier exists, it is determined whether the ticket identifier is valid on the block chain. Whether the ticket identifier is valid or not is determined by some transaction with respect to the address that is the ticket identifier. If there is no transaction for the address that is the ticket identifier, the ticket is determined to be valid, and if there is any transaction, the ticket is determined to be invalid.

  When the validity determination processing unit 41 determines that the ticket identifier is valid, the control processing unit 42 “enters” on the display device 72 of the computer visually recognized by the person in charge at the ticket gate location. Is displayed, or in the case of an automatic ticket gate system, the gate is opened so that the purchaser can pass through the gate. Further, the control processing unit 42 changes the “valid” information corresponding to the ticket identifier in the issued ticket identifier storage unit 21 of the ticket issuing system 2 to “invalid”. Then, from the address on the block chain of the field system 4, a predetermined transaction (for example, a transaction to transfer the virtual currency by "0") is sent to the address of the ticket identifier. When this transaction is approved on the blockchain, the ticket identifier is invalidated.

  On the other hand, when the validity determination processing unit 41 determines that the ticket identifier is invalid, “No entrance” is displayed on the display device 72 of the computer visually recognized by the person in charge at the ticket gate. Or, in the case of an automatic ticket gate system, the gate is closed so that the purchaser cannot pass through the gate. Depending on the case, a warning sound may be output or a warning may be displayed. That is, when it is determined that the ticket identifier is valid, a predetermined control process corresponding to validity is executed, and when it is determined that the ticket identifier is invalid, a predetermined control corresponding to invalidity is performed. The control process of is executed.

  The report reward processing unit 43 executes a process of paying the report reward to the reporter. For example, in the issued ticket identifier storage unit 21, the address on the block chain of the caller is associated with the ticket identifier invalidated by the notification (ticket identifier other than the ticket identifier invalidated by the address of the field system 4). If it is stored, refer to it to obtain the address of the caller on the blockchain. Then, the event organizer sends a transaction for remitting virtual currency equivalent to the reward from the address on the block chain of the event organizer to the address on the block chain of the informant. By approving this transaction on the blockchain, the event organizer can pay a reward to the whistleblower. The virtual currency equivalent to the reward may be at least the transaction cost of notification. Transaction cost is a virtual currency-based fee required for a transaction to be approved by a node.

  Alternatively, payment of a reward may be made via the ticket issuing system 2. That is, the ticket issuing system 2 identifies the ticket identifier invalidated by the notification and calculates the reward for the notification. Then, the calculated amount of the reward is charged to the event organizer. The event organizer pays for this request by a predetermined method such as a credit card. On the other hand, the ticket issuing system 2 identifies an address on the block chain of the whistleblower from the issued ticket identifier storage unit 21, and sends a transaction for sending virtual currency equivalent to the reward to the address. Approval of this transaction on the blockchain allows payment of the reward to the whistleblower.

  It should be noted that the management system 3 may access the ticket issuing system 2 and send a request for payment of the reward by notification. In this case, the management system 3 sends to the ticket issuing system 2 a request for payment of a reward by the notification, and the ticket issuing system 2 which receives the request specifies the ticket identifier invalidated by the notification and calculates the reward by the notification. . Then, the event organizer is charged with the calculated amount of reward. The event organizer pays for this request by a predetermined method such as a credit card. On the other hand, the ticket issuing system 2 specifies the address on the block chain of the whistleblower from the issued ticket identifier storage unit 21, and sends a transaction to send virtual currency equivalent to the reward to the address. Approval of this transaction on the blockchain allows payment of the reward to the whistleblower.

  Next, an example of a processing process using the ticket system 1 of the present invention will be described with reference to the flowcharts of FIGS. 4 to 7.

  First, the process of creating an event will be described.

  The event organizer inputs information about the event, such as the event name, classification, and capacity, by performing a predetermined operation on the management system 3, and sends an event creation request to the ticket issuing system 2. When the ticket issuing system 2 receives an event creation request from the management system 3, the event creation acceptance processing unit 20 accepts information on the event name, classification, and capacity, and the issued ticket identifier storage unit 21 stores the information. An area is secured (S100, S110).

  At this time, the event organizer may pay the ticket issuing system 2 a fee according to the fixed number (upper limit of ticket issuance).

  After the event creation processing is performed as described above, ticket sales are started. Then, the purchaser who purchases the ticket performs a predetermined operation on the purchaser terminal 5, and the ticket purchase acceptance processing unit 31 of the management system 3 requests information such as the event name, date and time, ticket classification, and number of tickets and a ticket purchase request. Accept (S200).

  Then, the number of tickets is compared with the capacity, and it is determined whether or not the capacity is exceeded (S210). If it is determined that the capacity is exceeded, the purchaser terminal 5 is notified (S220).

  On the other hand, when it is determined that the number of people is not exceeded, the payment processing unit 32 executes payment processing such as credit card payment in the same manner as normal ticket sales (S230).

  Further, after the settlement process is completed and before or in parallel with the settlement process, the ticket issuance request processing unit 33 informs the ticket issuing system 2 of event identification information such as an event name, ticket classification, number of tickets, purchaser. The seat information selected by, the customer identification information of the purchaser, etc. are sent as a ticket issuance request (S240).

  The ticket issuing system 2 that has received the ticket issuing request executes a ticket issuing process (S250). That is, when the ticket issuing system 2 receives the ticket issuing request from the management system 3 in the ticket issuing request receiving processing unit 22 (S300), it is determined whether the seat information selected by the purchaser is duplicated or not. The storage unit 21 is referred to and checked (S310). When it is determined that they overlap, a predetermined notification such as an error is sent to the management system 3. In addition, it may be determined whether or not the number of people for each division set by the management system 3 is exceeded. When it is determined that the number of persons in each category is exceeded, similarly, a predetermined notification such as an error is sent to the management system 3.

  When the ticket duplication check, the capacity excess check, and the like are normally performed, the ticket issuing processing unit 23 generates an address to be used on the block chain according to the number of tickets in the ticket issuing request. That is, an irreversible public key is derived using the private key, and an irreversible block chain address is derived from the public key (S320). Then, the generated address is used as the ticket identifier (S330). The address used as the ticket identifier is stored in the issued ticket identifier storage unit 21 in association with the customer identification information, classification, seat information, etc. accepted by the ticket issuance request acceptance processing unit 22. The status of the ticket identifier in the issued ticket identifier storage unit 21 is stored as "valid". FIG. 10 shows an example of the issued ticket identifier storage unit 21 in this state. Then, the ticket issue processing unit 23 encodes the ticket identifier (S340). An example of the coded ticket identifier is shown in FIG. FIG. 12 shows a case where the ticket identifier is two-dimensionally coded.

  The ticket information processing unit 24 returns information including the ticket identifier issued by the ticket issuing processing unit 23, the ticket identifier code, or the URL accessible to the ticket identifier code to the management system 3 as ticket information (S350).

  When the ticket information reception processing unit 34 of the management system 3 receives the ticket information from the ticket issuing system 2 (S260), it sends a part or all of the ticket information to the purchaser terminal 5 (S270). FIG. 11 is an example of the notification sent to the purchaser.

  Next, a case where the ticket purchaser resells the ticket will be described.

  When the purchaser resells the ticket, the ticket identifier or the code thereof may be displayed on the ticket resale site to indicate the existence of the ticket. In that case, the person who visually recognizes it (reporter) is the address on the blockchain of the reporter with respect to the address that is the ticket identifier displayed on the resale site or the address that is the ticket identifier converted from the code. Sends the specified transaction. By approving this transaction on the blockchain, the transaction for the address that is the resold ticket identifier is recorded.

  The whistleblower himself can send a transaction, and the whistleblower can make a notification via the ticket issuing system 2. In this case, a predetermined website of the ticket issuing system 2 accepts at least the ticket identifier that has been resold. When the notification processing unit 25 receives the notification of the ticket identifier, the notification processing unit 25 confirms whether the ticket identifier exists in the issued ticket identifier storage unit 21. From the above address, send a predetermined transaction to the address of the ticket identifier that received the notification. By approving this transaction on the blockchain, the transaction for the address that is the resold ticket identifier is recorded.

  When the notification processing unit 25 receives the address on the block chain of the notification person, the notification processing unit 25 associates the address on the block chain of the notification person with the issued ticket identifier storage unit 21 in association with the ticket identifier that received the notification. Remember. FIG. 13 shows an example of the issued ticket identifier storage unit 21 when the notification for the ticket identifier “NXXXXXXX” is received from the address “NAAAAAA” on the block chain.

  Next, a process when a ticket purchaser enters with a ticket will be described with reference to the flowchart of FIG.

  When entering the event site, the purchaser presents the ticket information code to the person in charge of the field system 4 or the automatic ticket gate system (S400). Then, the person in charge of the field system 4 reads the code presented by the code reading device. In the case of the automatic ticket gate system, the presented code is read by the code reading device (S410). Then, the read code is converted into a ticket identifier (S420).

  When the ticket identifier is normally converted, the validity determination processing unit 41 of the field system 4 refers to the issued ticket identifier storage unit 21 and confirms whether the converted ticket identifier exists (S430). By this confirmation, it can be confirmed whether the ticket identifier is issued by the ticket issuing system 2.

  When the converted ticket identifier exists in the issued ticket identifier storage unit 21, the validity determination processing unit 41 determines whether the ticket identifier is valid on the block chain (S440). That is, the presence / absence of a transaction for the address that is the ticket identifier is determined on the block chain (S450). If there is no transaction, it is determined that the ticket is valid (S460), and if there is any transaction, it is determined that the ticket is invalid (S470).

  Then, the control processing unit 42 executes the control process corresponding to the determination result of the validity determination processing unit 41 (S480). That is, when the validity determination processing unit 41 determines that the ticket identifier is valid, the control processing unit 42 causes the control processing unit 42 to perform a predetermined control process corresponding to “validity”, for example, a clerk at the ticket gate location of the ticket. The display 72 of the computer is displayed as "admission allowed", or in the case of the automatic ticket gate system, the gate is opened so that the purchaser can pass through the gate. Then, the control processing unit 42 sends a predetermined transaction (for example, a transaction for transferring "0" to the virtual currency) from the address on the block chain of the field system 4 to the address of the ticket identifier. When this transaction is approved on the blockchain, the ticket identifier is invalidated. Further, the control processing unit 42 changes the “valid” information corresponding to the ticket identifier in the issued ticket identifier storage unit 21 of the ticket issuing system 2 to “invalid”. FIG. 14 shows an example of the issued ticket identifier storage unit 21 in this state. FIG. 14 shows a case where the purchaser with the ticket identifier “NZZZZZ” has normally entered. In this case, “NBBBBBB” is an address on the block chain of the field system 4.

  On the other hand, when the validity determination processing unit 41 determines that the ticket identifier is invalid, the control processing unit 42 performs a predetermined control process corresponding to “invalid”, for example, a clerk at the ticket gate location visually recognizes it. When the automatic ticket gate system is closed, the gate is closed so that the purchaser cannot pass through the gate.

  By executing the above processing, it is possible to determine whether or not to enter the event.

  When paying a reward for a report, for example, the address on the block chain of the informant stored in the issued ticket identifier storage unit 21 is referred to and the address on the block chain of the informant is acquired. Then, the event organizer sends a transaction for remitting the virtual currency equivalent to the reward from the address on the block chain of the event organizer to the address on the block chain of the informant.

  On the other hand, when paying through the ticket issuing system 2, the management system 3 sends a request for payment of a reward by notification to the ticket issuing system 2, and the ticket issuing system 2 receiving this request invalidates the ticket identifier by the notification. And calculate the reward for the notification. Then, the calculated amount of the reward is charged to the event organizer. The event organizer pays for this request by a predetermined method such as a credit card. Then, the ticket issuing system 2 identifies the address on the block chain of the whistleblower from the issued ticket identifier storage unit 21, and sends a transaction to remit the virtual currency equivalent to the reward to the address.

  Further, the ticket issuing system 2 may voluntarily perform the payment process of the reward. In that case, the ticket issuing system 2 identifies the ticket identifier invalidated by the notification from the issued ticket identifier storage unit 21 and waits for the reward by the notification without waiting for the payment of the reward by the notification from the management system 3. calculate. Then, the calculated amount of the reward is charged to the event organizer. The event organizer pays for this request by a predetermined method such as a credit card. Then, the ticket issuing system 2 identifies the address on the block chain of the whistleblower from the issued ticket identifier storage unit 21, and sends a transaction for remitting virtual currency equivalent to the reward to the address.

  In the above-described embodiment, whether or not there is any transaction for the address that is the ticket identifier (whether the ticket identifier is valid) is determined on the blockchain after reading the code of the ticket identifier. , The decision is made on the blockchain periodically or irregularly at an arbitrary timing, and the decision is stored in the issued ticket identifier storage unit 21, and the validity of the ticket identifier is determined by the valid / invalid information. The determination may be made.

  In this case, the notification processing unit 25 identifies an address whose status is “valid” among the addresses which are the issued ticket identifiers stored in the issued ticket identifier storage unit 21 and periodically determines whether there is a transaction for the address. Make a decision on the blockchain either randomly or irregularly. Then, when it is determined that the transaction has an address (ticket identifier) with some transaction, the state corresponding to the ticket identifier stored in the issued ticket identifier storage unit 21 is changed to “invalid” and stored.

  By storing the ticket identifier in the issued ticket identifier storage unit 21 in advance in this manner, the validity determination processing unit 41 of the field system 4 determines the validity of the ticket identifier obtained by converting the code presented from the purchaser terminal 5. When performing the processing, the same purpose can be achieved by referring to the issued ticket identifier storage unit 21 without making a determination on the block chain.

  In each of the above-described embodiments, the case where the address on the block chain is used as it is as the ticket identifier has been described, but information obtained by converting the address on the block chain by a predetermined method may be used as the ticket identifier. In this case, the address on the block chain and the ticket identifier are stored in association with the issued ticket identifier storage unit 21. Then, when the notification for the ticket identifier is accepted, the issued ticket identifier storage unit 21 is referred to, the address on the corresponding block chain is specified, and the transaction for the address on the block chain is sent. Can be invalidated.

  Similarly, the validity determination processing unit 41 also refers to the issued ticket identifier storage unit 21 on the basis of the read ticket identifier, identifies the address on the corresponding block chain, and identifies the address on the block chain for the identified address. By judging the transaction, the validity of the ticket can be judged. Then, when it is determined that the ticket is valid, the ticket identifier can be invalidated by using the transaction on the blockchain to the address specified above.

  Note that the ticket identifier and the address on the block chain may not be stored in the issued ticket identifier storage unit 21, but may be appropriately converted using a conversion function.

  In each of the above-described embodiments, the case of an event ticket has been described, but the present invention is not limited to this and can be applied to tickets in general. For example, it can be applied to train and bus tickets, and boarding tickets for airplanes and ships. It is especially effective for tickets when it is desired to restrict the use by people other than the person himself / herself.

  Further, the ticket according to the present invention can also be used as a coupon (ticket) that can enjoy some service (various services such as discount and accommodation). In this case, resale of the coupon (ticket) can be similarly suppressed. In this case, “event organizer” may be read as “issuer of a coupon (ticket) such as a store”, “event” may be read as “product and / or service”, and “purchaser” may be read as “user”. The purchaser and the user are collectively called the recipient.

  By using the ticket system 1 of the present invention, resale can be suppressed with a simple mechanism.
