The token management unit may issue the token to the blockchain on the condition that the reception unit receives from the information terminal a purchase request indicating a desire to purchase the product, the purchase request including information specifying the first business identification information.

The token management unit may cause the blockchain to add acquisition information to the token indicating that the user has acquired the product from the second business operator, on the condition that the user has acquired the product from the second business operator.

The token management unit may cause the blockchain to add acquisition information to the token indicating that the user has acquired the product from the second business operator, on the condition that the user has paid the second business operator for the product.

The consideration may be digital currency managed on the blockchain.

The token management unit may, on the condition that the user has acquired the product from the second business, cause the blockchain to change the holder of the token from the user to the second business, and then from the second business to the first business.

The token management unit may change the holder of the token in the blockchain from the user to the second business operator, and then from the second business operator to the first business operator, on the condition that the user has paid the second business operator for the product.

The consideration may be digital currency managed on the blockchain.

The reward provision unit may provide the user with digital currency managed on the blockchain as the reward.

The reward provision unit may provide the user with a receipt token managed on the blockchain, which represents the right to receive a specified product or service, as the reward.

The token management unit may issue the token to the blockchain with the user as the holder.

The first business may be the manufacturer, investor, advertising business, or affiliated business of the product.

The first business may be a business that bears the funds for the benefit.
The second business may be a business that sells or provides the product to the user.
The identification unit may identify that the user has presented the token to the second business operator without the information processing device performing processing to have the user pay the price of the product to the second business operator.

A second aspect of the information processing method of the present invention includes the steps of receiving, executed by a processor, information specifying first business identification information for identifying a first business that handles a product from a user or an information terminal corresponding to the first business; issuing a token on a blockchain that associates user identification information for identifying the user and product identification information for identifying the product before the user acquires the product; identifying that the token has been presented to a second business that is different from the first business that corresponds to the first business identification information received in the receiving step; and providing a predetermined benefit to the user in response to identifying that the token has been presented to the second business in the identifying step.

[Outline of Information Processing System S]
1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes an information processing device 1, a user terminal 2, a first business operator terminal 3, and a second business operator terminal 4. The information processing system S may also include other devices such as servers and terminals.

The information processing device 1 is a computer that performs processing related to information stored on the blockchain. The blockchain is constructed in the memory unit of the information processing device 1 or in the memory unit of a device different from the information processing device 1. The blockchain may also be constructed in the memory units of multiple devices, in which case the information processing device 1 may be any one of those multiple devices.

Information stored on the blockchain includes, for example, transaction tokens that indicate the status of product transactions by users. Transaction tokens are stored, for example, by the blockchain on one or more storage units on the network, in association with identification information (ID: Identifier) that identifies the holder. The blockchain contains multiple blocks of data, and each block contains one or more transactions that indicate the transfer of the transaction token holder. Each block in the blockchain contains a hash value generated according to specified rules, and the accuracy of the entire blockchain is guaranteed by verifying the consistency of hash values between blocks.

The user terminal 2 is an information terminal used by a user. The first business operator terminal 3 is an information terminal used by a first business operator. The second business operator terminal 4 is an information terminal used by a second business operator different from the first business operator. A user is a person who trades goods. The first business operator is a person or organization that handles goods without providing the goods directly to the user, such as a product manufacturer, investor, advertising company, or affiliated business. The second business operator is a person or organization that provides goods directly to the user, such as a product seller (store, etc.).

The user terminal 2, the first operator terminal 3, and the second operator terminal 4 are, for example, computers such as smartphones, tablet terminals, or personal computers. The user terminal 2, the first operator terminal 3, and the second operator terminal 4 have an operation unit such as a touch panel or keyboard for accepting operations, and a display unit such as an LCD display for displaying information. The user terminal 2, the first operator terminal 3, and the second operator terminal 4 can communicate with the information processing device 1 via a network.

The following provides an overview of the processing executed by the information processing system S according to this embodiment. Before the user acquires a product handled by the first business, the information processing device 1 accepts a purchase request indicating a product specified by the user ((1) in Figure 1). The information processing device 1 issues a transaction token to the blockchain that associates user identification information (user ID) for identifying the user with product identification information (product ID) for identifying the specified product ((2) in Figure 1).

The user presents the transaction token to the second business ((3) in Figure 1) and then acquires the desired product from the second business ((4) in Figure 1). Based on the transaction token, the information processing device 1 determines that the user has presented the transaction token to the second business in order to acquire the product from the second business. For example, the information processing device 1 determines that the user has presented the transaction token to the second business on the condition that information indicating that the user has acquired the product from the second business has been added to the transaction token.

In response to determining that the user has presented the transaction token to the second business, the information processing device 1 provides the user with a predetermined benefit ((5) in Figure 1). The benefit may be, for example, digital currency or a predetermined token managed on a blockchain.

In this way, the information processing system S provides rewards to users based on transaction tokens that indicate the user's product transaction status stored on the blockchain. This eliminates the need for businesses, such as product sellers, to manage the product transaction status and the granting of rewards, thereby reducing the burden on businesses to provide rewards to users.

[Configuration of information processing system S]
FIG. 2 is a block diagram of an information processing system S according to this embodiment. In FIG. 2, arrows indicate the main data flows, and data flows other than those shown in FIG. 2 may also exist. In FIG. 2, each block indicates a functional configuration rather than a hardware (device) configuration. Therefore, the blocks shown in FIG. 2 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between blocks via any means, such as a data bus, a network, or a portable storage medium.

The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The information processing device 1 may be configured by two or more physically separate devices connected by wire or wirelessly. The information processing device 1 may also be configured by a cloud, which is a collection of computer resources.

The communication unit 11 has a communication controller for transmitting and receiving data between the user terminal 2, the first operator terminal 3, and the second operator terminal 4 via the network. The communication unit 11 notifies the control unit 13 of data received from the user terminal 2, the first operator terminal 3, and the second operator terminal 4 via the network. The communication unit 11 also transmits data output from the control unit 13 to the user terminal 2, the first operator terminal 3, and the second operator terminal 4 via the network.

The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, etc. The storage unit 12 pre-stores programs to be executed by the control unit 13. The storage unit 12 may be provided external to the information processing device 1, in which case data may be exchanged between the storage unit 12 and the control unit 13 via a network.

The control unit 13 has a reception unit 131, a token management unit 132, an identification unit 133, and a reward provision unit 134. The control unit 13 is a processor such as a CPU (Central Processing Unit), and functions as the reception unit 131, token management unit 132, identification unit 133, and reward provision unit 134 by executing programs stored in the memory unit 12.

The processing executed by the information processing system S will be described in detail below. First, the processing by the information processing device 1 to issue a transaction token will be described. A transaction token is information indicating the status of a product transaction by a user.

Figure 3 is a schematic diagram illustrating the process by which the information processing device 1 issues a transaction token. On the user terminal 2, the user performs an operation to specify a product that the user wishes to purchase (a product that the user plans to purchase) and that is handled by a first business (for example, a product manufactured by a manufacturer that is the first business) before acquiring the product. The user terminal 2 transmits a purchase request indicating that the user wishes to purchase the product specified by the user to the information processing device 1. The user terminal 2 may transmit the purchase request directly to the information processing device 1, or may transmit the purchase request to the information processing device 1 via the first business terminal 3.

A purchase request is, for example, information that associates a user's user ID with the product ID of a product specified by the user. The product ID of the product is pre-associated with a business ID that identifies a first business that handles the product, and the business ID of the first business can be identified from the product ID. The purchase request may also include the quantity of the product that the user wishes to purchase.

In the information processing device 1, the reception unit 131 receives from the user terminal 2 a purchase request indicating that the user wishes to purchase a specified product. On the condition that the reception unit 131 has received the purchase request, the token management unit 132 causes the blockchain to issue a transaction token before the user acquires the product indicated in the purchase request.

The token management unit 132 sends an issuance instruction to the blockchain to issue a transaction token containing information corresponding to the purchase request. The transaction token is, for example, information that associates the user ID of the user indicated in the purchase request with the product ID and quantity of the product indicated in the purchase request. This allows the information processing device 1 to manage user product purchase requests on the blockchain.

The transaction token may also include information indicating the business designated as the purchaser of the product (designated business). In this case, the token management unit 132 acquires information indicating the designated business that is pre-stored in the memory unit 12, and causes the blockchain to issue a transaction token that includes a business ID for identifying the designated business indicated by the acquired information. The designated business is, for example, a seller designated in advance by the first business.

The transaction token may also include an area capable of storing information indicating the payment status of the price of the product ("Receipt" in Figure 3), the delivery status of the product ("Delivery" in Figure 3), and the business from which the user actually purchased the product ("Purchasing Business" in Figure 3), although this information does not necessarily need to be stored at the time the transaction token is issued.

The issuance instruction is an instruction to have the blockchain associate the user ID indicated in the purchase request (the user ID of the user who is the holder) with a transaction token and issue it. The blockchain generates and stores the transaction token in association with the user ID in accordance with the issuance instruction sent by the token management unit 132. As a result, a transaction token indicating the transaction status of the product specified by the user is stored in the blockchain with the user as the holder before the user acquires the product.

Next, we will explain the process by which the information processing device 1 adds acquisition information to the transaction token. The acquisition information is information that indicates that the user has acquired (e.g., purchased) a product from a second business.

Figure 4 is a schematic diagram illustrating the process by which information processing device 1 adds acquisition information to a transaction token. In order to acquire the product indicated in the purchase request from the second business, the user pays the price (price) for the product to the second business and presents the transaction token to the second business.

The user pays the second business operator for the goods. The price for the goods is, for example, digital currency (crypto assets) managed on the blockchain. The user, for example, performs an operation on the user terminal 2 to pay the price for the goods to the second business operator. The user terminal 2, for example, sends a change instruction to the blockchain to change the holder of the digital currency corresponding to the price of the goods from the user to the second business operator. The blockchain stores information to change the holder of the digital currency from the user to the second business operator in accordance with the change instruction sent by the information processing device 1.

The user also performs an operation to display the transaction token on the user terminal 2. The second business operator uses the second business operator terminal 4 to acquire a token ID for identifying the transaction token presented by the user (the transaction token displayed on the user terminal 2). The second business operator terminal 4 acquires the token ID of the transaction token, for example, by capturing an image of the transaction token displayed on the user terminal 2 using an imaging unit, or accepts an operation to input the token ID of the transaction token from the second business operator. The second business operator then provides the product to the user, and the user acquires the product from the second business operator.

The second business operator terminal 4 transmits the token ID of the acquired transaction token to the information processing device 1. In the information processing device 1, the reception unit 131 receives the token ID of the transaction token transmitted by the second business operator terminal 4. When the reception unit 131 receives the token ID of the transaction token, the information processing device 1 determines that the user has paid the second business operator for the product and acquired the product from the second business operator.

The token management unit 132 causes the blockchain to change the holder of the transaction token from the user to the second business operator, on the condition that the reception unit 131 has received the token ID of the transaction token, i.e., the user has paid the second business operator for the product and acquired the product from the second business operator. The token management unit 132, for example, sends a change instruction to the blockchain to change the holder of the transaction token from the user to the second business operator. The blockchain stores information to change the holder of the transaction token from the user to the second business operator in accordance with the change instruction sent by the information processing device 1.

The token management unit 132 adds acquisition information to the blockchain for the transaction token corresponding to the token ID accepted by the acceptance unit 131. The acquisition information is, for example, information indicating that the user has acquired a product from a second business. The token management unit 132 sends an addition instruction to the blockchain to add the acquisition information to the transaction token. The addition instruction includes, for example, the token ID of the transaction token and the business ID of the second business.

The blockchain adds acquisition information to the transaction token in accordance with the addition instruction sent by the token management unit 132. For example, the blockchain stores the business ID of the second business ("Purchasing Business" in Figure 4), the fact that payment for the product has been made ("Receipt" in Figure 4), and the fact that delivery of the product has been made ("Delivery" in Figure 4) in the transaction token corresponding to the token ID indicated in the addition instruction. As a result, the transaction token stored in the blockchain records that the user has acquired the product from the second business.

After adding the acquisition information to the transaction token, the token management unit 132 causes the blockchain to change the holder of the transaction token again from the second business operator to the user. For example, the token management unit 132 sends a change instruction to the blockchain to change the holder of the transaction token from the second business operator to the user. The blockchain stores information to change the holder of the transaction token from the second business operator to the user in accordance with the change instruction sent by the information processing device 1.

In the example of Figure 4, the token management unit 132 adds acquisition information to the transaction token after changing the holder of the transaction token between the user and the second business, but it may also add acquisition information to the transaction token without changing the holder of the transaction token.

Next, we will explain the process by which the information processing device 1 provides a benefit to a user based on a transaction token. Figure 5 is a schematic diagram illustrating the process by which the information processing device 1 provides a benefit to a user based on a transaction token.

After acquiring a product from the second business, the user performs an operation on the user terminal 2 to request the provision of a special benefit. The user terminal 2 transmits the token ID of the transaction token for which the user wishes to receive a special benefit to the information processing device 1.

In the information processing device 1, the reception unit 131 receives, from the user terminal 2, the token ID of a transaction token for which the user wishes to receive a benefit. The token management unit 132 changes the holder of the transaction token in the blockchain from the user to the first business operator, on the condition that the reception unit 131 has received the token ID of the transaction token, i.e., that the user has requested the provision of a benefit. The token management unit 132, for example, sends a change instruction to the blockchain to change the holder of the transaction token from the user to the first business operator. The blockchain stores information to change the holder of the transaction token from the user to the first business operator in accordance with the change instruction sent by the information processing device 1.

In the example of Figure 5, the token management unit 132 changes the holder of the transaction token from the user to the first business operator on the condition that the user performs an operation on the user terminal 2 indicating that they wish to receive a benefit. However, the token management unit 132 may automatically change the holder of the transaction token from the user to the first business operator on the condition that acquisition information is added to the transaction token.

The identification unit 133 identifies, based on the transaction token stored on the blockchain, that the user has presented the transaction token to the second business to acquire a product from the second business. The identification unit 133, for example, acquires from the blockchain a transaction token corresponding to the token ID accepted by the acceptance unit 131, and determines whether acquisition information has been added to the acquired transaction token. If the identification unit 133 determines that acquisition information has been added to the transaction token, it identifies that the user has presented the transaction token to the second business; otherwise, it does not identify that the user has presented the transaction token to the second business. This allows the information processing device 1 to identify, based on the transaction token stored on the blockchain, whether the user has presented the transaction token to the second business, eliminating the need to query the second business for information.

The identification unit 133 may also identify, based on the acquired transaction token, that the user has presented the transaction token to the second business, provided that the second business is a business that has been pre-designated as a place to purchase the product. For example, if the business ID of the purchasing business (second business) included in the transaction token matches the business ID of the designated business included in the transaction token, the identification unit 133 determines that the second business is a business that has been pre-designated as a place to purchase the product; otherwise, the identification unit 133 determines that the second business is not a business that has been pre-designated as a place to purchase the product. The identification unit 133 identifies that the user has presented the transaction token to the second business, provided that acquisition information has been added to the transaction token and the second business is a business that has been pre-designated as a place to purchase the product. This allows the information processing device 1 to provide a benefit to the user only if the user has acquired a product from a specific business.

In the example of Figure 5, the identification unit 133 determines that the user has presented the transaction token to the second business operator after changing the holder of the transaction token from the user to the first business operator, but it may also determine that the user has presented the transaction token to the second business operator without changing the holder of the transaction token.

The reward provision unit 134 provides a predetermined reward to the user in response to the identification unit 133 identifying that the user has presented the transaction token to the second business. Here, the reward provision unit 134 may store information in the transaction token indicating that the reward has already been provided. This allows the reward provision unit 134 to not provide the reward to the user if information indicating that the reward has already been provided is already stored in the transaction token.

The reward provision unit 134 provides the user with, for example, digital currency (crypto assets) managed on the blockchain as a reward. In this case, the reward provision unit 134, for example, sends a change instruction to the blockchain to change the holder of the digital currency (reward) from the first business operator to the user. The blockchain stores information to change the holder of the digital currency from the first business operator to the user in accordance with the change instruction sent by the information processing device 1.

The reward provider 134 may also provide the user with a reward, for example, a receipt token that indicates the right to receive a specific product or service managed on the blockchain. In this case, the reward provider 134 sends an issuance instruction to the blockchain to issue the receipt token. The receipt token includes information indicating the product or service that the user is entitled to receive. The issuance instruction is an instruction to have the blockchain issue the receipt token in association with the user ID of the user who wishes to receive the reward (the user ID of the user who is the holder). The blockchain generates and stores the receipt token in association with the user ID in accordance with the issuance instruction sent by the reward provider 134.

This allows the information processing device 1 to provide benefits to users based on transaction tokens that indicate the user's product transaction status, which is managed on the blockchain.

[Information processing method flow]
6 is a flowchart illustrating an exemplary information processing method executed by the information processing device 1 according to this embodiment. A user performs an operation on the user terminal 2 to specify a product handled by a first business before acquiring the product. The user terminal 2 transmits a purchase request indicating a user's desire to purchase the product specified by the user to the information processing device 1. In the information processing device 1, the receiving unit 131 receives, from the user terminal 2, the purchase request indicating a user's desire to purchase the product handled by the first business specified by the user (S11).

The token management unit 132 issues a transaction token to the blockchain, provided that the reception unit 131 has received the purchase request, and before the user acquires the product indicated by the purchase request (S12).

To acquire the product indicated in the purchase request from the second business, the user pays the second business the price (price) for the product and presents the transaction token to the second business. The second business uses the second business terminal 4 to acquire a token ID for identifying the transaction token presented by the user to the second business (e.g., the transaction token displayed on the user terminal 2). The second business terminal 4 transmits the token ID of the acquired transaction token to the information processing device 1. In the information processing device 1, the reception unit 131 receives the token ID of the transaction token transmitted by the second business terminal 4 (S13).

The token management unit 132 adds the acquisition information to the blockchain for the transaction token corresponding to the token ID accepted by the acceptance unit 131 (S14).

After acquiring a product from the second business, the user performs an operation on the user terminal 2 to request the provision of a special benefit. The user terminal 2 transmits the token ID of the transaction token for which the user wishes to receive a special benefit to the information processing device 1. In the information processing device 1, the reception unit 131 receives the token ID of the transaction token for which the user wishes to receive a special benefit from the user terminal 2 (S15).

The identification unit 133 acquires from the blockchain a transaction token corresponding to the token ID accepted by the acceptance unit 131, and determines whether acquisition information has been added to the acquired transaction token (S16). If the identification unit 133 determines that acquisition information has not been added to the transaction token (NO in S17), the information processing device 1 terminates processing.

If the identification unit 133 determines that acquisition information has been added to the transaction token (YES in S17), the reward provision unit 134 provides a predetermined reward to the user (S18). The reward provision unit 134 provides the user with, for example, digital currency (crypto assets) or a received token managed on a blockchain as a reward.

[Effects of the embodiment]
In the past, in order to grant a user a reward for purchasing a product, the business had to manage the transaction status of the product and the granting of the reward, or the user had to submit evidence such as a receipt of the product purchase to the business. In contrast, according to the information processing system S of this embodiment, the information processing device 1 manages a transaction token indicating the user's transaction status of the product on a blockchain, and provides the user with a reward when the user presents the transaction token to acquire the product. As a result, the information processing system S does not require the business, such as the seller of the product, to manage the transaction status of the product and the granting of the reward, thereby reducing the burden on the business to provide rewards to users.

<Modification>
In the above-described embodiment, the information processing device 1 determines that the user has presented the transaction token to the second business based on the acquired information added to the transaction token, but in this modification, the information processing device 1 determines that the user has presented the transaction token to the second business based on the fact that the transaction token has been transferred. The following mainly describes the parts that are different from the above-described embodiment.

Figure 7 is a schematic diagram illustrating the process by which the information processing device 1 according to this modification identifies that a user has presented a transaction token to a second business.

The token management unit 132 causes the blockchain to change the holder of the transaction token from the user to the second business operator, on the condition that the reception unit 131 has received the token ID of the transaction token, i.e., the user has paid the second business operator for the product and acquired the product from the second business operator. The token management unit 132, for example, sends a change instruction to the blockchain to change the holder of the transaction token from the user to the second business operator. The blockchain stores information to change the holder of the transaction token from the user to the second business operator in accordance with the change instruction sent by the information processing device 1.

After the holder of the transaction token is changed to the second business operator, the token management unit 132 changes the holder of the transaction token from the second business operator to the first business operator in the blockchain. The token management unit 132, for example, sends a change instruction to the blockchain to change the holder of the transaction token from the second business operator to the first business operator. In accordance with the change instruction sent by the information processing device 1, the blockchain stores information changing the holder of the transaction token from the second business operator to the first business operator. This stores in the blockchain that the holder of the transaction token has changed from the user to the first business operator via the second business operator.

The identification unit 133 acquires the history of the transaction token holder from the blockchain. The identification unit 133 identifies that the user has presented the transaction token to the second business operator, provided that the acquired history indicates that the transaction token holder was changed from the user to the second business operator, and then from the second business operator to the first business operator.

As a result, the information processing device 1 in this example can provide benefits to users by identifying the user's product transaction status based on the transaction token transfer history, without adding acquisition information to the transaction token.

Furthermore, this invention will contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), "Build resilient infrastructure, promote inclusive and sustainable industrialization, and promote innovation and resilience."

The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and alterations are possible within the spirit of the invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of new embodiments resulting from the combination will also have the effects of the original embodiments.
