Embodiment < Configuration>
Embodiments of an information processing system and an information processing apparatus according to the present invention will be described below. In the present embodiment, an information processing method using an information processing device, a program installed to generate the information processing device, and a storage medium such as a USB, DVD, etc. storing the program are also provided by the present embodiment. be done. Programs to be installed on various terminals such as personal computers, smartphones, and tablets are also provided. "Or" in this embodiment is a concept including "and", and A or B means either A, B or both A and B. The information processing system of this embodiment may provide a platform.

As shown in FIGS. 1 and 2 , the information processing system may have a plurality of local information processing devices 100 and a central processing device 500 capable of communicating with each of the local information processing devices 100 . A part or all of the local information processing device 100 may be installed in a transportation facility. Each of the local information processing devices 100 includes a local storage unit 60, a first writing unit 11 that writes discrimination target information, which is an example of the first information, in a blockchain, and a local storage of history information, which is an example of the second information. and a second writing unit 21 that writes to the unit 60 . The local storage unit 60 is typically a database installed in the station premises (within the facilities of the station) or in facilities managed by the station. In this embodiment, the local information processing device 100 has a local server 20 and a node device 10 that can communicate with the local server 20 . The node device 10 has the first writing unit 11 and the local server 20 has the second writing unit 21 .

In a blockchain, transaction information is recorded by connecting blocks, which are collections of transaction information (transactions), in a chain. The transaction information may be hashed and written to the blockchain, for example by hashing with SHA-256 (Secure Hash Algorithm 256-bit). By writing to the blockchain, it is possible to prevent tampering and achieve tamper resistance. As an example, data may be encrypted using a private key when writing transaction information or the like to the blockchain. Then, when reading the transaction information written in the blockchain, the data can be decrypted using the public key. As another example, data may be encrypted using a public key when writing transaction information or the like to the blockchain. Also, when reading the transaction information written in the blockchain, the data can be decrypted using the private key.

In addition, if you want to perform an electronic signature (digital signature) using a blockchain, the data obtained by encrypting the original data and the hashed data of the original data with a private key, and the public key corresponding to the private key should be recorded on the blockchain. When reading the blockchain, by confirming that the hashed data of the original data matches the data decrypted with the public key, it is possible to verify that the person who recorded the data is the person who signed it. can be confirmed.

Any of a public type, a consortium type, a private type, etc. may be used as a blockchain. If a public type is used, mining will be performed. On the other hand, when using the consortium type, mining is not performed, and consensus building is performed by consensus among specific persons. Even when using the private type, mining is not performed and consensus building is based on internal approval. In addition, when using the consortium type, although there is a blockchain administrator, it is beneficial in that it does not become centralized.

The first information and the second information may have common information for linking them. Common information may be user information. In this case, the user information associates the first information written in the blockchain with the second information written in the local storage unit 60 . The user information is information that is also used for settlement, which will be described later. User information includes user identification information such as user identification number, user identification symbol, wallet ID, personal identification information such as user name, telephone number, email address, gender, age, credit card number, expiration date, debit Payment method information such as the card number of the card and account information for withdrawal may be included. Considering only making payments, the user information may include only payment method information. As the credit card number, information registered in the smartphone or information registered in association with the smartphone may be used.

In the following description, the discrimination target information is used as the first information and the history information is used as the second information, but the present invention is not limited to this.

The information processing system may have a mobile terminal 200 that displays transaction information (see FIG. 3). The mobile terminal 200 may be a mobile phone or a tablet terminal owned by the user. The mobile terminal 200 may be able to display the transaction information by installing a dedicated application on the mobile phone or tablet terminal.

The mobile terminal 200 has a terminal display unit 210 and a terminal display unit 220. In the case of a smartphone or a tablet terminal, the display screen of the mobile terminal 200 functions as both the terminal display unit 210 and the terminal display unit 220. Also serves as. The transaction information may be displayed on the terminal display unit 210 as code information such as a QR code (registered trademark). Such a display may be realized by an operation on the terminal display section 220. FIG. By installing a predetermined program (application) in mobile terminal 200, mobile terminal 200 that functions as part of the information processing system in the present embodiment may be realized.

The code information includes ticket type information such as a ticket code, ticket issuer information such as a company code, user identification information such as a wallet ID, token information such as a ticket token (for example, a one-time token), and a reading unit provided in the automatic ticket gate 105. 110 may include installation location information (eg, location code) for identifying the installation location of 110, and action information indicating an action type such as entry or exit. Also, in the case of a plan ticket, the code information may include valid period information (for example, period code) of the ticket. As an example, the wallet ID may be a character string (eg, 66 characters) representing the user's wallet public key (eg, 33 bytes) in hexadecimal notation.

As an example, the determination target information includes ticket type information, issuer information, validity period information, user information, token information, and the like. On the other hand, history information includes user information, installation location information, action information, and the like. The transaction information (transaction) that will be recorded on the blockchain consists of input and output, but the token information is used to process the input and output.

By recording the determination target information in the blockchain and storing the history information in the central storage unit 560 such as the cloud storage unit, while limiting the information recorded in the blockchain, the information necessary for payment etc. can be stored in the central storage unit 560. can be stored in Therefore, useful information can be stored in the central storage unit 560 or the like while maintaining high processing performance in the blockchain. Central storage unit 560 is a storage unit included in central processing unit 500 . The central processing unit 500 has a central information processing unit 520 that can communicate with the local information processing unit 100 via the Internet or the like. may be made.

The discrimination target information may be minimum information for passing through the ticket gate. If the ticket is not a plan ticket but a normal ticket, the discrimination object information does not have to have valid period information. In addition, when a single business operator issues a ticket instead of a mode in which a plurality of business operators participate, the determination target information does not need to have issuer information. Further, when there is only one type of ticket, the discrimination target information may not have the ticket type information. By limiting the information to be determined in this way, it is possible to reduce the amount of information written in the blockchain, and effectively maintain high processing performance in the blockchain.

Fraud can be prevented by using a block chain as a means of recording discrimination target information. In addition, by using blockchain, it is possible to share information among multiple businesses easily and at low cost.

When the transaction information displayed on the mobile terminal 200 is read by the automatic ticket gate 105 at the station, the read transaction information may be written to the local storage unit 60 as well as to the blockchain. At this time, the identification target information (first information) of the transaction information may be written to the blockchain, and the history information (second information) of the transaction information may be written to the local storage unit 60 .

The local information processing apparatus 100 may have a determination unit 120 that determines whether or not the transportation facility can be used based on the transaction information when the transaction information is read by the reading unit 110 . When the determination unit 120 determines that the transaction information is valid, the determination unit 120 transmits a command permitting entry to the automatic ticket gate 105, etc. As a result, the user can pass through the automatic ticket gate 105. As a result, it becomes possible to enter or leave facilities such as stations.

The local server 20 may be an edge server such as an API server. Further, the node device 10 may have the determination unit 120 and a determination program for use in the determination unit 120 may be installed in the node device 10 .

The information processing system of this embodiment may be used as a substitute for a general train ticket. Also, it may be used as a substitute for a plan ticket. When used as a plan ticket, the determining unit 120 may determine whether or not to use not only stations but also leisure facilities, buses, taxis, ships, and other facilities and equipment (see FIG. 4).

In the information processing system (for example, platform) of the present embodiment, it may be possible to assign and transfer the user's ticket-related rights and virtual currency. To give an example of transferring rights related to a ticket, information related to rights such as ticket type information and a token may be hashed, signed with a private key, and transmitted together with a public key. Information about such transfer is written in the blockchain, and the fact that the right has been transferred from the sender (for example, Mr. C) to the receiver (for example, Mr. D) is written in the blockchain. The authenticity of the recipient (e.g., Mr. D) who has received the right is the identification information such as the recipient's ID read by the code information such as the QR code that is recognized when the recipient uses the right, and the ticket type information. The identification information such as the ID of the receiver and the ticket type information written in the block chain may be checked by the determination unit 120 so as to be checked.

An example of information flow is shown.
When a ticket is issued via the Internet or a ticket vending machine, the relevant information (transaction information) is written in the blockchain (see Fig. 3). As a result, code information indicating transaction information can be displayed on the mobile terminal 200 . When the code information displayed on the mobile terminal 200 is read by the reading unit 110 of the automatic ticket gate 105 at the station, the transaction information in the code information is compared with the transaction information written in the block chain, and valid transaction information is obtained. The determination unit 120 determines whether there is any. As an example, when the transaction information in the code information (for example, discrimination target information) and the transaction information written in the block chain (for example, discrimination target information) match, the discrimination unit 120 determines that the transaction information is valid, If the transaction information in the code information and the transaction information written in the block chain do not match, the determination unit 120 may determine that the transaction information is invalid.

As an example, when the code information is read by the reading unit 110 of the automatic ticket gate 105 installed at Station A, the determination target information in the transaction information indicated by the code information is determined by the node device 10 installed at Station A. to determine whether it is valid transaction information (see FIG. 3). If it is determined that the determination target information is valid, the automatic ticket gate 105 opens in response to a command from the determination unit 120, allowing the user to enter the station. Also, in this case, the discrimination target information is written to the block chain, and the history information is stored in the local storage unit 60 in the A station. On the other hand, when the transaction information in the code information and the transaction information written in the block chain do not match and the determination unit 120 determines that the transaction information is not valid, the automatic ticket gate 105 is closed and the user cannot enter the A station premises.

Also, the local server 20 at station A, for example, an edge server, writes the transaction information to the central storage unit 560 of the central processing unit 500, which is a cloud server in a cloud such as AWS (Amazon Web Service). The central processing unit 500, which is a cloud server, receives information on usage histories from the edge servers of many stations and other facilities, and the information on the usage histories is stored in the central storage unit 560. FIG.

The information about the usage history written in the cloud server is stored in the local storage unit 60 installed at the B station by the local server 20, which is the edge server of the B station. In this manner, the local storage unit 60 installed at each station has the same information as the central storage unit 560 has.

When the user who entered from A station exits at B station, the code information is read by the reading unit 110 of the automatic ticket gate 105 at B station. When the code information is read by the unit 110, the determination object information in the transaction information indicated by the code information is determined by the node device 10 installed at the B station to determine whether it is valid transaction information. If it is determined that the determination target information is valid, the automatic ticket gate 105 opens in response to a command from the determination unit 120, allowing the user to exit the station. Also in this case, the determination target information is written to the block chain, and the history information is stored in the local storage unit 60 in the B station. On the other hand, if the transaction information in the code information does not match the transaction information written in the block chain and the determination unit 120 determines that the transaction information is not valid, the automatic ticket gate 105 is closed and automatically The user cannot exit from the premises of the B station via the ticket gate 105. - 特許庁

Since the central storage unit 560 stores which station the user entered and exited from, it is possible to determine the usage fee based on this usage history. In the case of the post-pay type, the charge according to the usage status of each user is fixed at regular intervals. Then, a payment request based on a credit card is made according to the determined charge, and the payment is made. The fee determination and/or payment request may be performed by the calculation unit 530 of the central processing unit 500 . If the history information includes user information, installation location information, and action information, it is possible to determine who entered and exited from which location. become.

The reader 110 may be installed in a railway station, in a bus or taxi, or in a vessel such as a ferry (see FIG. 4). Further, the reading unit 110 may be installed at the target facility. The facilities may be various facilities such as amusement parks, zoos, botanical gardens, and museums. For vessels such as ferries, the reader 110 may be installed at the counter.

The calculation unit 530 may calculate profit distribution information using the information on the use of transportation or the information on the use of facilities stored in the central storage unit 560 .

Multiple readers 110 may be managed by multiple businesses. The reading unit 110 and the businesses may be associated, and the calculation unit 530 may calculate profit distribution information for each business. When the user gets on at A station managed by α company and gets off at B station managed by β company, the station between A station and B station managed by α company The calculation unit 530 may calculate the profit distribution information according to the usage fee at the company β and the usage fee managed by the company β.

The calculation unit 530 may calculate profit distribution information regardless of the travel distance or travel section for transaction information read by taxi, bus, or ship. When adopting this aspect, the sections and times of available taxis may be set in advance. When the available time is set, the taxi may be available for a certain period from the time when the transaction information is read by the reader 110 installed in the taxi. The calculation unit 530 may calculate the benefit distribution information according to the used distance or section, without being limited to such a mode. Identification information is assigned to each of the reading units 110, and when the transaction information is read, the identification information of the reading unit 110 is associated with the transaction information, and is written to the block chain by the first writing unit 11. may be written to the local storage unit 60 by the second writing unit 21 . As described above, the information written in the local storage unit 60 is stored in the central storage unit 560, and is also stored in the local storage unit 60 installed at another station or the like. The associated identification information and transaction information of the reading unit 110 may be written to the blockchain by the first writing unit 11 together with the date and time, or may be written to the local storage unit 60 by the second writing unit 21. . Based on the identification information of the reading unit 110 , the second writing unit 21 may write the information about the station, bus, or taxi used by the user into the local storage unit 60 . However, the information is not limited to such a mode, and the first writing unit 11 may write information about the station, bus, or taxi used by the user to the blockchain.

A predetermined coefficient is applied to each of the railroad section (fare), the number of times of taxi use, the number of times of bus use, the number of times of facility use, etc., stored in the central storage unit 560, and these are aggregated for each operator. The calculation unit 530 may calculate the profit sharing information. For example, L1 x railroad usage fee + L2 x number of times taxi is used + L3 x number of times bus is used + L4 ₁ x m ₁ number of times facility is used + ··· + L4 _n x m _n facility is used. The calculation unit 530 may calculate the profit distribution information for each business operator by calculating the calculation results for each business operator.

The time when the transaction information is first read by the reading unit 110 may be used to determine the period of use of the transportation or facility according to the transaction information. Management of the usage period may be performed by the management unit 580 . The management unit 580 may be installed in the central processing unit 500, or may be installed in a local area such as each station or facility (see management unit 80 in FIG. 1). The transaction information and the usage start time may be associated and stored in the local storage unit 60 . As an example, for a certain period of time, such as 24 hours, 72 hours, 1 day, 3 days, or 1 week from the time the transaction information is first read by the reader 110, may be made freely available. In addition, for example, when used as a plan ticket, since the period in which the plan is valid is fixed, within the effective period, 24 hours, 72 hours, 24 hours, 72 hours, or 24 hours from the time when the transaction information is first read by the reading unit 110. Subject transportation and facilities may be freely available for a period of time, such as one day, three days, or one week. Limitation of usage period may be performed by a script (locktime).

The information handling system may handle virtual currency. Transaction information may be purchased using virtual currency. Code information such as a QR code may also be displayed when using virtual currency. The code information (first code information) that displays the transaction information and the code information (second code information) that is displayed when using the virtual currency may be different code information (for example, another QR code). . It should be noted that the transaction information may be purchased using cash, a credit card, a debit card, or the like, without being limited to such a mode. Also, the same code information may be used for code information (first code information) for displaying transaction information and for code information (second code information) displayed when using a virtual currency. It may be displayed in code.

The management unit 580 may manage the value of the virtual currency so that it depreciates over time. The value of the virtual currency may be gradually depreciated, may be depreciated to 0 after a certain period of time, or may be depreciated in stages. When purchasing virtual currency from cash, a certain premium may be added. The virtual currency may be a regional virtual currency that can be used only in a specific region. The degree of depreciation and premium value may be set differently for each region. As an example, when the value of cash to be converted is "1", the value of the converted virtual currency may be "1 + p" (0% < p ≤ 50%). "p" may be from 10% to 30%.

Transaction information may be purchased at a bargain price when a virtual currency issued by a predetermined issuer is used. In this case, the type of virtual currency used is determined by the management unit 580, and if the management unit 580 determines that the virtual currency is issued by a predetermined issuer, the transaction information can be purchased at a discounted price. You may do so. Further, when the transaction information is purchased with a virtual currency issued by a predetermined issuer, a premium may be given to the virtual currency. In this case as well, the management unit 580 determines the type of virtual currency used, and if the management unit 580 determines that the virtual currency is issued by a predetermined issuer, the virtual currency managed by the mobile terminal 200 A premium may be given to the currency. By adopting such a mode, it is possible to increase the possibility of using the virtual currency wherever the user has moved, and it is expected that the use of the virtual currency by the user will be encouraged. Also, when purchasing transaction information, a virtual currency that can be used in the region may be purchased at the same time. good too. In this case, it may be managed by the management unit 580 so that the period during which the purchased virtual currency can be used matches the period during which the transaction information is valid. For example, if the transaction information is valid for one week from the first use, the virtual currency will be available for one week from the first use, and the management unit will set the value of the virtual currency to 0 after one week. 580 may depreciate the value of virtual currency.

The virtual currency may be virtual coins, points, electronic money, etc., or two or more of these. If two or more of these are used as the virtual currency, the management unit 580 may manage such that the virtual coin can be converted into electronic money but not into points. The management unit 580 may manage so that electronic money cannot be converted into virtual coins and points. The management unit 580 may manage so that points can be converted into virtual coins and points. The exchange ratio between different types of assets may be set arbitrarily, or may be set by a supply and demand prediction model (dynamic pricing). When the supply and demand forecast model is employed, the management unit 580 may have an artificial intelligence function and generate the supply and demand forecast model using the adoption variables and the adoption coefficients for the adoption variables. In this case, a change to a different asset can be made according to the demand-supply balance between assets.

A sufficient amount of transactions, such as 10,000, may be available in an issued token for a predetermined period of time. This transaction will be consumed each time a state change occurs, such as passing through a ticket gate or using a facility. Transactions remaining after the usage period has expired may be deleted by the management unit 580 or may be collected by the management unit 580 .

When a blockchain is used, the discriminating unit 120 may discriminate usable service information based on transaction information using colored coins. The available service information may vary depending on the type of transportation available, the type of facility, the period of availability, and the like. As for the types of means of transportation, the railway company that can be used, the section that can be used, the section that can be used for taxis, the section that can be used for buses, and the like may be different.

The first writing unit 11, the second writing unit 21, the determination unit 120, etc., the calculation unit 530, the management unit 580, etc. of the present embodiment may be realized by one unit (control unit), It may be implemented by different units. The functions of a plurality of "parts" may be integrated and implemented in one unit (control unit). Further, the first writing unit 11, the second writing unit 21, the discrimination unit 120, etc., and the calculation unit 530, the management unit 580, etc. may be implemented by a circuit configuration.

≪Method≫
Next, an example of the information processing method according to this embodiment will be described with reference to FIG.

A user purchases transaction information for which the user is a target via the Internet or using a terminal terminal such as a ticket vending machine at a station. By adopting a form in which transaction information can be purchased via the Internet, it is possible to promote the use of tourists coming to Japan from overseas, and to omit the paperwork related to the purchase of transaction information at facilities such as stations. can. When purchasing via the Internet, the purchased personal computer may serve as the terminal device. When purchasing at a ticket vending machine, the ticket vending machine may serve as the terminal device.

When the transaction information is purchased, the mobile terminal 200 owned by the user can display the transaction information as code information such as a QR code. When the mobile terminal 200 reads information displayed on the terminal device, sends an e-mail to a specified e-mail address from the terminal device, or communicates from the terminal device by short-range communication such as Bluetooth, the mobile terminal 200 acquires the code information, and the code information may be displayed on the mobile terminal 200 . When purchasing transaction information with the mobile terminal 200, the mobile terminal 200 may be able to display code information such as a QR code.

The user causes the mobile terminal 200 to display the code information, and causes the reading section 110 such as a QR code reading section installed at the ticket gate of the station to read the code information. When the code information is read by the reading unit 110 in this manner, the determining unit 120 determines whether or not the transportation facility can be used according to the transaction information displayed as the code information. When the code information is read by a reading unit 110 such as a QR code reading unit installed at the entrance of the facility, the discrimination unit 120 discriminates whether or not the facility can be used based on the transaction information displayed as the code information.

In the case of using a railway or the like, when leaving a destination station, the code information is read by a reading unit 110 such as a QR code reading unit installed at the ticket gate of the station.

In the facility, if the determination unit 120 determines that the facility can be used, the first writing unit 11 may write the time when the use of the facility started to the blockchain, or the second writing unit 21 may write the local It may be stored in the storage unit 60 . When leaving the facility, the code information may be read by a reading unit 110 such as a QR code reading unit installed at the exit of the facility, for example. In this case, the time when the user leaves the facility can be managed. The calculation unit 530 may calculate profit distribution information according to the length of stay at the facility. In this case, a high profit distribution may be made to a facility with a long stay, and a low profit distribution may be made to a facility with a short stay. As an example, the calculation unit 530 may calculate the profit distribution information using the calculation result (K×T) obtained by multiplying the profit coefficient K per unit time for each facility by the length of stay T. By adopting such a mode, profits can be distributed more fairly.

When using a taxi or bus, the transaction information may be read by the reader 110 installed in the taxi or bus. In this case, the calculation unit 530 may calculate the profit distribution information regardless of the travel distance within the target section.

"effect"
Next, the effects of the present embodiment having the above-described configuration, which have not yet been described, will be mainly described. Any configuration used in the "effect" can be adopted in the present invention even if it is not explained in the "configuration".

If the local information processing device 100 adopts a mode having the determination unit 120 that determines the validity of the transaction by comparing the information read by the reading unit 110 with the information written in the block chain, the reading unit A quick match can be made between the information read at 110 and the information written to the blockchain.

In particular, when the reading unit 110 and the discrimination unit 120 are connected via a wired or wireless line (mobile line or the like) without going through the Internet, the processing speed can be increased. As a result of a demonstration experiment, when discrimination was performed by a discrimination unit connected via the Internet, the information read by the reading unit 110 of the automatic ticket gate 105 was discriminated once as the median value of the standard distribution. A time of 600 to 700 ms was required per time. On the other hand, when the reading unit 110 and the discriminating unit 120 are connected by a wired or wireless line (such as a mobile line) without going through the Internet, the processing time is 125 to 150 ms per time as the median value of the standard distribution. We could do it, and we could do it much faster. In general, processing within 200 ms is required for smooth processing when a station is congested, but this embodiment was able to satisfy this requirement.

Also, the first information, which is part of the information read by the reading unit 110, is written to the blockchain by the first writing unit 11, and the part of the information read by the reading unit 110 is the first information. When the second information including different information is written to the local storage unit 60 by the second writing unit 21, writing to the block chain or writing to the local storage unit 60 is performed depending on the type of information. can do. Therefore, necessary information can be stored in the local storage unit 60 while reducing the load on the blockchain.

When the second information includes user information and information about the installation location of the reading unit 110, it is possible to store in the local storage unit 60 which station the reading unit 110 was typically used by the target user. , and thus can be stored in the central storage unit 560 of the cloud server. Therefore, it is possible to charge the user based on this information.

When the first information and the second information have common information, the first information written in the blockchain can be associated with the second information stored in the local storage unit 60 or the central storage unit 560. . Therefore, the information written in the blockchain and the information stored in the local storage unit 60 or the central storage unit 560 can be linked when necessary and used for analysis or the like.

When the same information as the information stored in the local storage unit 60 of the local information processing device (first local information processing device) 100 with the central processing unit 500 is obtained, and the information is stored in the central storage unit 560 , the information obtained by the automatic ticket gate 105 of each station can be managed by the central processing unit 500 as well.

Also, the information stored in the local storage unit 60 of a local information processing device (first local information processing device) 100 stored in the central storage unit 560 can be transferred to another local information processing device (second local information processing device). device) 100, and information stored in the local storage unit 60 of the local information processing device (first local information processing device) 100, which is the other local information processing device (second local information processing device) 100 In the case of storage, information obtained at one station can be shared and held at another station. When such a mode is adopted, for example, since data related to the boarding station is stored in the local storage unit 60 of the alighting station, the user exits from the automatic ticket gate 105 of the alighting station (when not of the post-pay type). When doing so, it becomes possible to settle the account using the data on the boarding station. The transmission of information from the local 60 of the local information processing device 100 to the central processing device 500 and the storage of the transmitted information in the central storage unit 560 are performed periodically (for example, 1 It may be performed once a minute, etc.). In the case of the post-pay type, since settlement is made collectively, the transmission of information from the local 60 of the local information processing device 100 to the central processing unit 500 and the storage of the transmitted information in the central storage unit 560 are It may be performed less frequently, such as once a day, once a week, or the like.

According to the aspect in which both the transportation facility and the facility can be used by the transaction information displayed on the mobile terminal 200 , both the movement by the transportation facility and the use of the destination facility can be realized by the mobile terminal 200 . Therefore, there is no need to have multiple tickets, and it is very useful in that it can be used simply with the mobile terminal 200 alone. As an example, by digitizing special passenger tickets, it is possible to seamlessly process the purchase of special tickets, the use of vehicles and facilities, and the settlement of accounts without the need to go through ticket collection and exchange at a station window or a travel agency. In addition, it is very useful in that it can be completed only with the mobile terminal 200 such as a smart phone.

If a calculation unit 530 is provided that calculates profit distribution information using the information on the use of transportation or the information on the use of facilities stored in the storage unit 60, profit distribution can be performed according to the state of use. can be done. In the currently used unlimited-use tickets, etc., profits are not distributed according to usage conditions, so if this mode is adopted, profits can be distributed according to the actual situation. .

When the reading unit 110 and the business operators are associated with each other and the calculation unit 530 automatically calculates the profit distribution information for each business operator, the profit to be allocated to each business operator can be automatically calculated. useful in terms of

With respect to the transaction information read by a taxi or bus, if the calculation unit 530 calculates the profit distribution information regardless of the distance traveled or the section traveled, profit distribution can be easily performed for taxis and buses. can. Note that regarding railroads, the calculation unit 530 may calculate the profit distribution information based on the boarding section. In this case, profit distribution can be performed according to the utilization section.

In the case of adopting a mode in which the usage period of a transportation facility or facility based on the transaction information is determined using the time when the transaction information is first read by the reading unit 110, the usage start time is used to determine the usage end time. and can provide services that allow free use of railways and facilities for a certain period of time.

When the discriminating unit 120 adopts a mode in which available service information is discriminated from transaction information using colored coins, types of available transportation facilities and/or facilities, available service providers, etc. services can be provided by distinguishing between

When the mode of the present embodiment is used as a plan ticket, it is possible to reduce operational costs in terms of issuance and management, and clerical costs (personnel costs, printing costs, transportation costs, administrative costs) involved in operations. More specifically, when digitizing special tickets using a blockchain platform and code information such as QR codes, ticket sales at ticket counters and ticket inspections at tourist facilities can be omitted, reducing clerical costs. can be greatly reduced. In addition, according to this aspect, it is possible to eliminate or reduce the sales consignment commission paid to the travel agency or the like.

In addition, unlike a magnetic ticket, high security can be enhanced (forgery, unauthorized use, unauthorized resale, etc. can be prevented), and authenticity can be checked at low cost. In addition, it becomes possible to centrally accumulate action histories such as boarding, using, purchasing, etc., and it is possible to promote utilization of data, for example, it can be used for marketing activities.

In this embodiment, integration of service and payment using a smart contract may be adopted. More specifically, when adopting a mode in which delivery of securities and payment are mutually conditioned so that unless one is performed, the other will not be performed. Costs can also be reduced.

Since the validity determination processing of the magnetic ticket is complicated, the introduction and maintenance of the automatic ticket gate 105 require high costs. The system can be introduced at low cost.
