Description

[Technical field]

[0001] The present invention relates to an information processing device, an information processing method, and a program. [Background technology]

[0002] Conventionally, there is known a service in which an introducing user introduces a product to an introduced user, and when the introduced user purchases the product, a reward is provided to the introducing user. Patent Document 1 discloses a technology for tracking customer behavior on the Internet by issuing cookies to the customer's terminal. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-283083 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, since cookies are information stored in a terminal, there is a risk that the cookies may be deleted or rewritten from the terminal. For example, if cookies are deleted from a terminal used by an introduced user, the behavior of the introduced user cannot be tracked, and therefore, even if the introduced user purchases a product, it is not possible to provide a reward to the introducing user who introduced the product to the introduced user via a website.

[0005] The present invention has been made in consideration of these points, and aims to provide a reward to referring users. [Means for solving the problem]

[0006] An information processing device according to a first aspect of the present invention has an authentication token issuing unit that executes a process to issue an authentication token to an introducing user, who is an introducer, to prove that the introducer has been authenticated as an introducer of a product or service, a product or service; an introduction token issuing unit that executes a process to issue an introduction token to an introduced user of the product to prove that the introduced user of the product has been introduced to the product by the introducing user, on the condition that the authentication token corresponding to the product has been issued to the introducing user; and a reward granting unit that executes a process to grant a reward to the introducing user when a provider of the product corresponding to the introduction token provides the product to the introduced user after the introduction token has been issued.

[0007] The introduction token issuing unit may execute a process for issuing the introduction token when the introducing user requests issuance of the introduction token for the introduced user.

[0008] The introduction token issuing unit may execute a process for issuing the introduction token to a follower who follows the introducing user in a social networking service (SNS) as the introduced user.

[0009] The introduction token issuing unit may execute a process for issuing the introduction token when the introduced user requests issuance of the introduction token corresponding to the product.

[0010] The introduction token issuing unit may execute a process for issuing the introduction token to a viewer who has viewed content introducing the commercial material created by the introducing user as the introduced user.

[0011] The introduction token issuing unit may execute processing to issue the introduction token with the further condition that the introducing user refers to the introduction content in which the product is introduced to the introduced user and indicates that the introduction content is a positive evaluation of the product.

[0012] The authorization token issuing unit may execute a process for issuing the authorization token when the provider requests issuance of the authorization token to the introducing user.

[0013] The certified token issuing unit may execute processing to issue the certified token when at least one of the following conditions is met: the number of followers of the introducing user on a SNS is greater than or equal to a predetermined threshold, and the provider has provided the product to the introducing user.

[0014] The referral token may have an expiration date, and the bonus granting unit may further execute processing to grant the bonus when the referred user completes the procedure to pay for the product within the expiration date of the referral token.

[0015] The benefit may have a granting deadline set, and the benefit granting unit may further execute processing to grant the benefit if the date on which the referral token issuing unit issues the referral token has not passed the granting deadline.

[0016] The reward granting unit may execute a process to grant the reward to at least one of the multiple different introducing users when a procedure is performed to pay for the product corresponding to the multiple introduction tokens after multiple introduction tokens corresponding to each of the multiple different introducing users, the multiple introduction tokens corresponding to a common product, are issued to the introduced user.

[0017] The privilege granting unit may refer to the payment history of the referred user after the introduction token is issued to determine whether or not a procedure has been performed to pay for the product corresponding to the introduction token.

[0018] An information processing method according to a second aspect of the present invention includes the steps of: executing a process executed by a computer to issue a certification token to an introducing user, who is the introducer, to prove that the introducing user has been certified as an introducer of a product or service; executing a process to issue an introduction token to the introducing user to prove that the introducing user has been introduced to the product by the introducing user, on the condition that the certification token corresponding to the product has been issued to the introducing user; and executing a process to grant a benefit to the introducing user when the introducing user has completed procedures to pay for the product corresponding to the introduction token after the introduction token has been issued.

[0019] A program relating to a third aspect of the present invention causes a computer to function as: an authentication token issuing unit that executes processing to issue an authentication token to an introducing user, who is the introducer, to prove that the introducer has been authenticated as an introducer of a product or service, a referral token issuing unit that executes processing to issue an introduction token to an introduced user to prove that the introduced user of the product was introduced to the product by the introducing user, on the condition that the authentication token corresponding to the product has been issued to the introducing user; and a bonus granting unit that executes processing to grant a bonus to the introducing user when, after the referral token has been issued, the introduced user performs procedures to pay for the product corresponding to the referral token.

[Figure 6] FIG. 2 is a sequence diagram showing a flow of processing executed by the information processing system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] [Outline of Information Processing System S] 1 is a diagram for explaining an overview of an information processing system S. The information processing system S is a system used for providing an information processing service. The information processing service is a service that gives a benefit to an introducing user when the introducing user introduces a product to an introduced user and the introduced user purchases or uses the product.

[0023] The commercial material is a product or a service. The introducing user is a person who introduces a product, for example, a member of an information processing service. The introduced user is a person to whom a product is introduced. The introduced user may be a member of the information processing service or a non-member of the information processing service. The benefit is a reward given to the introducing user who introduced the introduced commercial material to the introduced user who purchased the introduced commercial material in return for his / her contribution, for example, cash, points, cryptocurrency, etc. The information processing service may further include an online shopping service that sells commercial materials on the Internet. The information processing system S has a provider terminal 1, an introducing user terminal 2, an introduced user terminal 3, and an information processing device 4.

[0024] The provider terminal 1 is a terminal used by a provider, such as a smartphone, a tablet terminal, a personal computer, etc. The provider is a person who provides commercial materials, such as a manufacturer that produces products, a seller that sells products, a service provider that provides services, etc.

[0025] The introducing user terminal 2 is a terminal used by the introducing user, and is, for example, a smartphone, a tablet terminal, a personal computer, or the like.

[0026] The introduced user terminal 3 is a terminal used by the introduced user, and is, for example, a smartphone, a tablet terminal, a personal computer, or the like.

[0027] The information processing device 4 is a device that manages the information processing service, and is, for example, a server. For example, a dedicated application program (hereinafter, referred to as a "dedicated app") for providing the information processing service is installed in each of the provider terminal 1, the introducing user terminal 2, and the introduced user terminal 3. The dedicated app is provided with a plurality of function items for providing various functions, such as a function for registering a commodity, a function for introducing a commodity, a function for purchasing a commodity, etc., and the information processing device 4 acquires information from each terminal and presents the information via the dedicated app. The information processing device 4 may also acquire information from each terminal and present the information via a website of the information processing service.

[0028] The information processing device 4 manages the track record of an introducing user introducing a product to an introduced user by using the blockchain B. The blockchain B is a system that issues a predetermined token used in the information processing service. The predetermined token is, for example, a non-fungible token.

[0029] The predetermined tokens include an authorization token and an introduction token. The authorization token is a token for proving that the introducer has been authorized, and is used as a condition for granting an issue token (described later) to the introducing user. The issue token is a token for proving that the introduced user has been introduced a product by the introducing user, and is used as a condition for granting a benefit to the introducing user.

[0030] Certified tokens and referral tokens are distinguished by the type of information contained in each token, information indicating the type of token defined in the information processing service (e.g., a string for identifying the type of token), or the type of token issued by blockchain B (e.g., whether it is a soulbound token, which is a non-transferable, non-fungible token, or a transferable, non-fungible token, etc.). The processes executed by the information processing system S will be described below.

[0031] First, the information processing device 4 registers information about a product to be introduced by an introducing user in the information processing service. For example, first, when a provider uses a dedicated app on the provider terminal 1 to input information about a product that the introducing user wishes to introduce in the information processing service, the provider terminal 1 transmits a registration request including information about the product input by the provider to the information processing device 4 ((1) in FIG. 1). Then, the information processing device 4 executes a registration process for the product ((2) in FIG. 1).

[0032] Next, the information processing device 4 certifies the introducing user as an introducer who will introduce the product to the introducing user. For example, first, when the introducing user performs an operation to select a product that the introducing user wishes to introduce from among multiple products registered in the information processing service using a dedicated application of the introducing user terminal 2, the introducing user terminal 2 transmits an authorization request to the information processing device 4 to have the introducing user authorized as an introducer who will introduce the selected product ((3) in FIG. 1). Then, upon receiving the authorization request, the information processing device 4 executes an issuing process of an authorization token corresponding to the introducing user and the product, thereby certifying the introducing user as an introducer who will introduce the product ((4) in FIG. 1).

[0033] Next, the information processing device 4 records the performance of the introducing user introducing the product to the introduced user. For example, when the introducing user specifies an introduced user using a dedicated application of the introducing user terminal 2 and introduces a product to the specified introduced user, the information processing device 4 executes an introduction token issuing process corresponding to the introducing user, the introduced user, and the product, on the condition that an authorization token corresponding to the introducing user and the product has been issued, thereby recording the performance of the introducing user introducing the product to the introduced user ((5) and (6) in FIG. 1).

[0034] Then, when an introduced user who has been introduced to a product by an introducing user goes through the procedure to pay the provider for the product, the information processing device 4 grants a benefit to the introducing user identified by the introduction token, provided that an introduction token corresponding to the introduced user and the product has been issued ((7) and (8) in Figure 1).

[0035] In this way, the information processing system S can prevent the information indicating the track record of the introducing user introducing the product to the introduced user from being deleted or rewritten by issuing an introduction token as information indicating the track record of the introducing user introducing the product to the introduced user. As a result, the information processing system S can provide a reward to the introducing user. The configuration of the information processing device 4 will be described below.

[0036] [Configuration of information processing device 4] Fig. 2 is a block diagram of an information processing device 4. In Fig. 2, arrows indicate main data flows, and data flows other than those shown in Fig. 2 may exist. In Fig. 2, each block indicates a configuration in functional units, not a configuration in hardware (device) units. 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.

[0037] The information processing device 4 includes a communication unit 41, a storage unit 42, and a control unit 43. The information processing device 4 may be configured by connecting two or more physically separated devices by wire or wirelessly. The information processing device 4 may also be configured by a cloud that is a collection of computer resources.

[0038] The communication unit 41 has a communication controller for transmitting and receiving data between the provider terminal 1, the introducing user terminal 2, or the introduced user terminal 3 via the network. The communication unit 41 notifies the control unit 43 of data received via the network from the provider terminal 1, the introducing user terminal 2, or the introduced user terminal 3. In addition, the communication unit 41 transmits data output from the control unit 43 to the provider terminal 1, the introducing user terminal 2, or the introduced user terminal 3 via the network.

[0039] The storage unit 42 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, etc. The storage unit 42 may be provided outside the information processing device 4, in which case data may be exchanged between the storage unit 42 and the control unit 43 via a network. The storage unit 42 stores in advance a program to be executed by the control unit 43. The storage unit 42 stores information about users who use the information processing service (e.g., user ID, user gender, user age, credit card number, etc.). The storage unit 42 also stores a product management database that manages information about products.

[0040] Fig. 3 is a diagram showing an example of the configuration of a product management database. In the example shown in Fig. 3, the product management database stores a provider ID, a product ID, a certification condition, a benefit content, and a benefit deadline in association with each other.

[0041] The provider ID is information for identifying the provider of the product. The product ID is information for identifying the product. The certification condition is a condition for issuing a certification token, and is, for example, a condition set by the provider. The certification condition is, for example, at least one of the following conditions: the number of followers of the introducing user on the SNS is equal to or greater than a predetermined threshold, and the provider has provided the product to the introducing user. The predetermined threshold is, for example, a value set by the provider. The certification condition may be a condition set by an administrator of the information processing device 4. The reward content is the content of the reward to be granted to the introducing user, and is, for example, the content set by the provider. The reward content may be the content set by the administrator of the information processing device 4. The granting deadline is a deadline for granting the reward, and is, for example, a deadline set by the provider or the administrator of the information processing device 4.

[0042] 2, the control unit 43 has a registration unit 431, an authorization token issuing unit 432, an introduction token issuing unit 433, a payment management unit 434, and a bonus granting unit 435. The control unit 43 is a processor such as a CPU (Central Processing Unit), and functions as the registration unit 431, the authorization token issuing unit 432, the introduction token issuing unit 433, the payment management unit 434, and the bonus granting unit 435 by executing a program stored in the storage unit 42.

[0043] [Registration process] First, a description will be given of the commercial material registration process executed by the information processing device 4. The registration unit 431 executes the commercial material registration process in response to a commercial material registration request from a provider. Specifically, the registration unit 431 executes the commercial material registration process by executing the following two steps.

[0044] As a first step, the registration unit 431 acquires a request to register a product from the provider terminal 1. For example, first, when the provider selects a function item for registering a product from a menu of a dedicated application of the provider terminal 1, the provider terminal 1 displays a registration screen. The registration screen is a screen for registering a product to be introduced by an introducing user in the information processing service, and is provided with input fields for inputting information about the product desired to be introduced, such as a field for inputting the provider's ID, a field for inputting the product's ID, a field for inputting certification conditions, a field for inputting the contents of a special offer, and the like.

[0045] In this case, when the provider inputs information into the input fields on the registration screen, the provider terminal 1 transmits a registration request including information on the product input by the provider to the information processing device 4. Then, the information processing device 4 receives the registration request from the provider terminal 1.

[0046] In a second step, the registration unit 431 registers the product. Specifically, the registration unit 431 registers the product by storing information about the product included in the acquired registration request in a product management database.

[0047] [Authorization token issuance process] Next, a description will be given of the authorization token issuing process executed by the information processing device 4. The authorization token issuing unit 432 executes a process for issuing an authorization token to an introducing user. Specifically, the authorization token issuing unit 432 executes the process for issuing an authorization token by executing the following two steps.

[0048] As a first step, the certified token issuing unit 432 acquires a certification request for a product from the introducing user terminal 2. The certification request is a request to have the introducing user certified as an introducer of the product, and includes, for example, the introducing user ID and the product ID.

[0049] For example, first, when the introducing user selects a function item for receiving certification for introducing a product from the menu of the dedicated application of the introducing user terminal 2, the provider terminal 1 displays a product selection screen. The product selection screen is a screen for the introducing user to receive certification for introducing a product, and displays, for example, a list of products registered in the information processing service (for example, a list of products whose information is stored in a product management database).

[0050] In this case, when the introducing user selects a product for which he / she wishes to receive introduction certification from the list of products displayed on the product selection screen, the introducing user terminal 2 transmits a certification request including the introducing user's ID and the ID of the product selected by the introducing user to the information processing device 4. The certification request may further include the ID of the provider who provides the product. Then, the information processing device 4 acquires the certification request from the introducing user terminal 2.

[0051] As a second step, the authorized token issuing unit 432 executes a process for issuing an authorized token to the introducing user. Specifically, when the authorized token issuing unit 432 acquires a authorization request from the introducing user terminal 2, the authorized token issuing unit 432 causes the blockchain B to issue an authorized token corresponding to the introducing user and the product selected by the introducing user, and grants the authorized token to the introducing user.

[0052] For example, first, the certified token issuing unit 432 transmits the ID of the introducing user and the ID of the product included in the certification request to the blockchain B. The blockchain B issues a token ID and issues a soulbound token, which is a non-fungible token that is non-transferable and includes the ID of the issued token, the ID of the introducing user, and the ID of the product, as the certified token.

[0053] Fig. 4 is a diagram showing an example of the configuration of an authorized token. In the example shown in Fig. 4, the authorized token is associated with a token ID, an introducing user ID, and a product ID. Note that the authorized token is not limited to the example shown in Fig. 4, and may further be associated with a provider ID and type information indicating that the type of the token is an authorized token.

[0054] Returning to FIG. 2, when blockchain B issues a certification token, the certification token issuing unit 432 transmits the certification token (e.g., a token ID, etc.) to the introducing user terminal 2 that sent the certification request. The introducing user terminal 2 then stores the acquired certification token. In this way, the information processing device 4 can prevent the certification of the introduction of a product from being transferred to another user by having blockchain B issue a soulbound token as the certification token. Note that the certification token issuing unit 432 may also have blockchain B issue a transferable non-fungible token as the certification token.

[0055] The authorization token issuing unit 432 may execute a process for issuing an authorization token when a predetermined condition related to the product selected by the introducing user is satisfied. Specifically, the authorization token issuing unit 432 executes a process for issuing an authorization token when, as a predetermined condition, a provider of the product selected by the introducing user requests issuance of an authorization token to the introducing user.

[0056] For example, first, when the certified token issuing unit 432 acquires a certification request from the introducing user terminal 2, it notifies the provider terminal 1 corresponding to the provider of the product that the introducing user has accepted the request for certification to introduce the product. In this case, the certified token issuing unit 432 may notify the provider terminal 1 of information (e.g., a profile, etc.) regarding the introducing user who wishes to be certified to introduce the product.

[0057] When the provider terminal 1 receives a notification from the information processing device 4, it displays information about the introducing user and information indicating the product. When the provider permits the introducing user to introduce the product and performs an operation on the provider terminal 1 to authorize the introduction of the product to the introducing user, the provider terminal 1 transmits a request to issue an authorization token to the information processing device 4. Then, when the authorization token issuing unit 432 receives the request to issue an authorization token from the provider terminal 1, it executes processing to issue an authorization token to the introducing user. In this way, the information processing device 4 can grant an authorization token to the introducing user authorized by the provider of the product.

[0058] The information processing device 4 may execute a process for issuing an authorization token corresponding to a user designated by the provider. The user designated by the provider is a user selected by the provider from among multiple users of the information processing service, or a person who has individually contracted with the provider to introduce a product (a user who uses the information processing service or a user who does not use the information processing service). For example, when the provider first performs an operation to input information on a user who is authorized as an introducer who will introduce a product in the provider terminal 1, the provider terminal 1 transmits an authorization token issuance request including the ID of the user selected by the provider to the information processing device 4. Then, when the authorization token issuance unit 432 acquires the authorization token issuance request from the provider terminal 1, it executes a process for issuing an authorization token to the introducing user.

[0059] The information processing device 4 may also execute a process for issuing an authentication token corresponding to the first product to an introducing user who has previously introduced a second product provided by a provider of the first product. The first product and the second product are, for example, different products (for example, products of the same series or products of different series, etc.) and are provided by the same provider.

[0060] For example, first, when the authorization token issuing unit 432 receives an issuance request for an authorization token corresponding to a first product from the provider terminal 1, the authorization token issuing unit 432 refers to the blockchain B and searches for an authorization token including the ID of the provider of the first product. Then, if a corresponding authorization token has been issued as a search result, the authorization token issuing unit 432 executes a process for issuing an authorization token corresponding to the introducing user identified by the introducing user's ID included in the authorization token and the first product.

[0061] The authorization token issuing unit 432 may execute a process for issuing an authorization token when the introducing user satisfies authorization conditions corresponding to a product as a predetermined condition. Specifically, the authorization token issuing unit 432 executes a process for issuing an authorization token when the introducing user satisfies the authorization conditions stored in the product management database in association with the ID of the product included in the authorization request.

[0062] For example, if the certification condition is that the number of followers of the introducing user on the SNS is equal to or greater than a predetermined threshold, the certified token issuing unit 432 first transmits the ID of the introducing user included in the certification request to an SNS server (not shown) that manages the SNS, and acquires information indicating the number of followers of the introducing user on the SNS. The introducing user ID in this case is an ID commonly used in the information processing service and the SNS. Then, if the number of followers of the introducing user on the acquired SNS is equal to or greater than a predetermined threshold included in the certification condition, the certified token issuing unit 432 executes processing to issue a certified token.

[0063] Also, for example, if the certification condition is that the provider has provided a product to the introducing user, first, the certified token issuing unit 432 refers to the provision history (e.g., payment history) in the information processing service, and executes processing for issuing a certified token if the history includes a history of the provider providing a product to the introducing user. In this manner, the information processing device 4 can grant a certified token to an introducing user who satisfies a predetermined condition. Note that the certified token issuing unit 432 refers to the provision history in the information processing service, and if the history does not include a history of the provider providing a product to the introducing user, it may notify the introducing user terminal 2 that the provider needs to provide the product to the introducing user in order to be certified.

[0064] [Token issuing process] Next, a description will be given of the process of issuing an issue token executed by the information processing device 4. The introduction token issuing unit 433 executes a process for issuing an introduction token corresponding to an introducing user and a product to an introduced user on the condition that an authorized token corresponding to the product has been issued to the introducing user. Specifically, the introduction token issuing unit 433 executes the process for issuing an introduction token by executing the following three steps.

[0065] As a first step, the introduction token issuing unit 433 acquires an introduction request. The introduction request is a request for issuance of an introduction token for recording the performance of the introducing user introducing a product to the introduced user, and includes, for example, the introducing user ID, the introduced user ID, and the product ID. The introduction request may include the provider ID and the token ID corresponding to the authorization token.

[0066] Specifically, the introduction token issuing unit 433 acquires an introduction request from the introducing user. For example, first, when the introducing user selects a function item for introducing a product from a menu of a dedicated application of the introducing user terminal 2, the introducing user terminal 2 displays an introduction screen. The introduction screen is a screen for the introducing user to introduce the product to the introduced user, and is provided with, for example, an item for specifying the product to be introduced, an item for specifying the introduced user who is the introduction destination, and an item for inputting the introduction content.

[0067] In this case, when the introducing user specifies a product and an introduced user on the introduction screen and performs an operation to input the introduction content, the introducing user terminal 2 transmits an introduction request including an introduction message indicating the input introduction content, the introducing user's ID, the specified introduced user's ID, and the specified product ID to the information processing device 4. Then, the introduction token issuing unit 433 acquires the introduction request from the introducing user terminal 2. Thereafter, the introduction token issuing unit 433 transmits the acquired introduction message to the introduced user terminal 3 corresponding to the acquired ID of the introduced user.

[0068] As a second step, the introduction token issuing unit 433 searches for an authorization token corresponding to a specific introducing user and a specific product. The authorization token corresponding to a specific introducing user and a specific product is, for example, a non-fungible token including a combination of the acquired introducing user ID and the acquired product ID, a non-fungible token including a combination of the acquired introducing user ID, the acquired product ID, and type information indicating that the type of the token is an authorized token, a soulbound token including a combination of the acquired introducing user ID and the acquired product ID, etc.

[0069] Specifically, the introduction token issuing unit 433 refers to the blockchain B and searches for an authorization token corresponding to a combination of a specific introducing user and a specific product. When acquiring a token ID from the introducing user terminal 2, the introduction token issuing unit 433 may refer to the blockchain B and search for an authorization token corresponding to the acquired token ID.

[0070] As a third step, the introduction token issuing unit 433 executes a process for issuing an introduction token when an authorized token corresponding to a specific introducing user and a specific product has been issued. Specifically, when the introduction token issuing unit 433 acquires an introduction request from the introducing user terminal 2, it causes the blockchain B to issue an introduction token corresponding to the introducing user, the introduced user designated by the introducing user, and the product designated by the introducing user, and grants the introduction token to the introduced user.

[0071] For example, first, the introduction token issuing unit 433 transmits the introducing user ID, the introduced user ID, and the product ID included in the introduction request to the blockchain B. The blockchain B issues a token ID, and issues a non-fungible, transferable token including the issued token ID, the introducing user ID, the introduced user ID, and the product ID as an introduction token. The introduction token issuing unit 433 may cause the blockchain B to issue an introduction token further including type information indicating that the type of token to be issued is an introduction token.

[0072] FIG. 5 is a diagram showing an example of the configuration of an introduction token. In the example shown in FIG. 5, the introduction token is associated with a token ID, an introducing user ID, an introduced user ID, and a product ID. Note that the introduction token is not limited to the example shown in FIG. 5, and type information indicating that the type of the token is an introduction token may be further associated with the introduction token. In addition, the introduction token may be further associated with an issue date when the introduction token is issued and an expiration date of the introduction token (for example, one week, one month, one year, etc.). The expiration date may be a deadline predetermined in the information processing device 4, or may be a deadline determined by the provider of the product.

[0073] Returning to FIG. 2, when the blockchain B issues an introduction token, the introduction token issuing unit 433 transmits the introduction token (for example, a token ID, etc.) to the introduced user terminal 3 corresponding to the acquired ID of the introduced user. After that, the introduced user terminal 3 stores the acquired introduction token.

[0074] Here, when an introducing user introduces a product to an introduced user with negative content, even if the introduced user subsequently purchases the product, it may not be appropriate to give a privilege to such an introducing user. Therefore, the information processing device 4 may execute a process for issuing an introduction token when an introducing user introduces a product to an introduced user with positive content. Specifically, the introduction token issuing unit 433 executes a process for issuing an introduction token with a further condition that the introducing user refers to the introduction content introducing the product to the introduced user and indicates that the introduction content is a positive evaluation of the product.

[0075] For example, first, the introduction token issuing unit 433 analyzes the introduction message acquired from the introducing user terminal 2, and determines whether or not the content of the introduction message is a positive evaluation of the product. Whether or not the content of the introduction message is a positive evaluation of the product may be determined based on whether or not a negative evaluation is included, or whether or not the proportion of positive evaluations among positive and negative evaluations is high. The introduction token issuing unit 433 determines whether or not the evaluation of the product is positive using, for example, a known technique (e.g., emotion analysis including sentiment analysis, etc.).

[0076] The introduction token issuing unit 433 further executes an introduction token issuing process when the introduction content of the introduction message is a positive evaluation of the product. In this way, the information processing device 4 can grant a privilege to the introducing user who introduced the product to the introduced user with positive content.

[0077] In the above, an example has been described in which the introduction token issuing unit 433 executes a process of issuing an introduction token corresponding to an introduced user designated by an introducing user, but the present invention is not limited to this. For example, the introduction token issuing unit 433 executes a process for issuing an introduction token to a follower who follows the introducing user on an SNS as an introduced user.

[0078] For example, first, when the introducing user performs an operation to post an introduction message for a specified product on the SNS using the introducing user terminal 2, the introducing user terminal 2 posts the introduction message on the SNS and transmits an introduction request to the information processing device 4. In this case, the introduction request includes the introducing user ID and the product ID. Furthermore, the introducing user ID included in the introduction request is an ID commonly used in the information processing service and the SNS. Upon receiving the introduction request, the introduction token issuing unit 433 inquires about the followers of the introducing user by transmitting the introducing user ID to an SNS server (not shown) that manages the SNS.

[0079] Then, the introduction token issuing unit 433 executes an introduction token issuing process corresponding to the follower's ID (introduced user's ID) acquired from the SNS server for each follower. In this way, the information processing device 4 can grant a reward for an introduction message posted by an introducing user on the SNS.

[0080] The introduction token issuing unit 433 may execute an introduction token issuing process for a viewer who has viewed the introduction content as an introduced user. The introduction content is a content that introduces a product created by an introducing user, and is, for example, a Web page. For example, the introduction content includes the ID of the introducing user who created the content and the ID of the product introduced in the content.

[0081] In this case, first, when the introduced user performs an operation to access the introduced content on the introduced user terminal 3, the introduced user terminal 3 displays the introduced content. Then, when the introduced user terminal 3 accesses the introduced content, the introduction token issuing unit 433 acquires the ID of the introduced user from the introduced user terminal 3, and executes an introduction token issuing process corresponding to the acquired ID of the introduced user, the introducing user ID set in the introduced content accessed by the introduced user terminal 3, and the ID of the product. In this way, the information processing device 4 can grant a privilege to the introducing user who created the introduced content in response to the introduced user viewing the introduced content.

[0082] The introduction token issuing unit 433 may execute a process for issuing an introduction token when an introduced user requests issuance of an introduction token corresponding to a product. For example, the introduction content is provided with a support button for supporting the introducing user who introduces the product, and the ID of the introducing user is set to the support button.

[0083] In this case, first, when the introduced user presses the support button in the introduced content displayed on the introduced user terminal 3, the introduced user terminal 3 transmits an introduction token issuance request including the introducing user ID set in the support button to the information processing device 4. Then, when the introduction token issuance unit 433 acquires an introduction token issuance request from the introduced user terminal 3, it executes an introduction token issuance process corresponding to the acquired introducing user ID. In this way, the information processing device 4 can grant a privilege to the introducing user recommended by the introduced user.

[0084] The introduction token issuing unit 433 may execute a process for issuing an issue token when the introducing user satisfies an issuance condition corresponding to the product. For example, the introduction token issuing unit 433 executes a process for issuing an introduction token when the introducing user satisfies, as an issuance condition, a certification condition stored in the product management database in association with the ID of the product included in the introduction request.

[0085] [Granting process] Next, a description will be given of the reward granting process executed by the information processing device 4. When the introduced user performs a procedure to pay for the product corresponding to the introduction token after the introduction token is issued, the reward granting unit 435 executes a process to grant a reward to the introducing user. Specifically, the information processing device 4 executes the process to grant a reward to the introducing user by executing the following two steps.

[0086] As a first step, the payment management unit 434 executes a process for paying for the merchandise. For example, first, when the introduced user performs an operation for making payment for the merchandise using a dedicated app on the introduced user terminal 3, the introduced user terminal 3 transmits a payment request to the information processing device 4. The payment request is a request for payment for the merchandise, and includes, for example, the introduced user's ID, the merchandise's ID, and the ID of a token (introduction token) corresponding to the merchandise. The payment request may further include a credit card number. Then, upon receiving the payment request, the payment management unit 434 executes a payment process for settling the merchandise's price.

[0087] As a second step, when the payment management unit 434 executes the payment process, the reward granting unit 435 executes a process for granting a reward to the introducing user. For example, first, the reward granting unit 435 refers to the blockchain B and searches for an introducing token that includes the acquired token ID or a combination of the acquired introduced user ID and product ID.

[0088] Then, when the corresponding introduction token is issued as a search result, the reward granting unit 435 executes a process for granting a reward to the introducing user identified by the introduction token. For example, the reward granting unit 435 grants to the introducing user a reward of the content stored in the product management database in association with the ID of the acquired product. When the reward granting unit 435 executes a process for granting a reward to the introducing user, the reward granting unit 435 may notify the introducing user terminal 2 of a message that the reward has been granted.

[0089] The reward granting unit 435 may execute a process for granting a reward to the introducing user of a product when the introduced user performs a procedure for paying for the product in a shopping service or store other than the information processing service. Specifically, the reward granting unit 435 executes the process for granting a reward to the introducing user by executing the following three processes.

[0090] As a first step, the reward granting unit 435 acquires the payment history of the introduced user after the introduction token is issued. The payment history includes, for example, information indicating the object of the payment, the date and time of the payment, etc. The reward granting unit 435 acquires the payment history of the introduced user at a predetermined interval (for example, daily, weekly, monthly, etc.) from the introduced user terminal 3, the provider terminal 1 of the provider who provides the merchandise, or an external server (not shown) that provides a shopping service.

[0091] In a second step, the reward granting unit 435 refers to the payment history of the introduced user to determine whether or not a procedure for paying for the product corresponding to the introduction token has been performed. Specifically, the reward granting unit 435 determines whether or not the payment history of the introduced user includes a payment for the product identified by the introduction token corresponding to the introduced user.

[0092] As a third step, the reward granting unit 435 executes a process for granting a reward to the introducing user when the introduced user makes a payment for the product. In this way, the information processing device 4 can grant a reward to the introducing user who introduced the product to the introduced user based on the performance of the introduced user paying for the product.

[0093] Here, if the introduced user purchases the product immediately after the product is introduced by the introducing user, the probability that the product was purchased due to the introduction of the product by the introducing user is high, and if the introduced user purchases the product some time after the product is introduced by the introducing user, the probability that the product was purchased due to the introduction of the product by the introducing user is low. Therefore, the bonus granting unit 435 may further execute a process for granting a bonus when the introduced user performs a procedure to pay for the product within the validity period of the introduction token.

[0094] For example, first, the reward granting unit 435 determines whether the expiration date included in the corresponding introduction token has passed the acquisition time when the payment request was acquired from the introduced user terminal 3. Then, when the reward granting unit 435 determines that the expiration date has not passed the acquisition time, it executes a process for granting a reward to the introducing user. In this way, the information processing device 4 can grant a reward to the introducing user when there is a high probability that the introduced user has purchased a product due to the introduction of the product by the introducing user.

[0095] The reward granting unit 435 may further execute a process for granting a reward when the date on which the introduction token is issued by the introduction token issuing unit 433 has not passed the benefit deadline. For example, the reward granting unit 435 determines whether the issue date of the introduction token has passed the benefit deadline. Then, when it is determined that the benefit deadline has not passed the issue date of the introduction token, the reward granting unit 435 executes a process for granting a reward to the introducing user. In this way, the information processing device 4 can provide the introducing user with a motivation to introduce a product to the introduced user early.

[0096] When the introduced user is introduced by a plurality of different introducing users for the same product, the reward granting unit 435 may execute a process for granting a reward to at least one of the plurality of introducing users. Specifically, when the introduced user performs a procedure for paying for the product corresponding to the plurality of introduction tokens after a plurality of introduction tokens corresponding to the plurality of different introducing users, which correspond to a common product, are issued to the introduced user, the reward granting unit 435 executes a process for granting a reward to at least one of the plurality of different introducing users.

[0097] The reward granting unit 435, for example, executes a process of equally dividing the reward among the number of introducing users and granting the reward to each introducing user. The reward granting unit 435 may execute a process of granting a reward to an introducing user who first introduced the introduced user among the multiple introducing users. The reward granting unit 435 may also execute a process of granting a reward to an introducing user designated by the introduced user among the multiple introducing users.

[0098] For example, first, when the introduced user performs a payment procedure for the price of a product on the introduced user terminal 3 and performs an operation to designate one introducing user from among multiple introducing users, the introduced user terminal 3 transmits the ID of the introducing user designated by the introduced user to the information processing device 4. Then, the reward granting unit 435 executes a process for granting a reward to the introducing user designated by the introduced user. In this way, the information processing device 4 can grant a reward to at least one of the multiple introducing users even if multiple introducing users have introduced a common product to the introduced user.

[0099] [Processing of information processing system S] Next, a description will be given of the flow of processing executed by the information processing system S. Fig. 6 is a sequence diagram showing the flow of processing executed by the information processing system S. This processing starts when the introducing user terminal 2 transmits a certification request including an introducing user ID and a product ID to the information processing device 4 (S1).

[0100] When the certification token issuing unit 432 obtains a certification request from the introducing user terminal 2, it causes blockchain B to issue a certification token including the introducing user ID and the product ID included in the certification request, and grants the certification token to the introducing user by sending the issued certification token to the introducing user terminal 2 (S2).

[0101] The introducing user terminal 2 transmits an introduction request including the introduction message, the introducing user ID, the introduced user ID, the product ID, and the certified token ID to the information processing device 4 (S3). Upon receiving the introduction request, the introduction token issuing unit 433 transmits the obtained introduction message to the introduced user terminal 3 corresponding to the obtained introduced user ID (S4).

[0102] The introduction token issuing unit 433 refers to the blockchain B, and searches for an authorization token including the acquired ID of the introducing user, the ID of the introduced user, the ID of the product, and the ID of the authorization token, thereby determining whether or not the authorization token has been issued (S5). If the introduction token issuing unit 433 determines that the corresponding authorization token has not been issued (NO in S5), it ends the process.

[0103] On the other hand, if the introduction token issuing unit 433 determines that the corresponding certified token has been issued (YES in S5), it causes blockchain B to issue an introduction token including the introducing user's ID, the introduced user's ID, and the product ID included in the acquired introduction request, and grants the introduction token to the introduced user by sending the issued introduction token to the introduced user terminal 3 (S6).

[0104] The introduced user terminal 3 transmits a payment request including the introduced user ID, the product ID, and the introduction token ID to the information processing device 4 (S7). When the payment management unit 434 acquires the payment request, it executes the payment process (S8). When the payment management unit 434 executes the payment, the benefit granting unit 435 refers to the blockchain B and searches for an introduction token including the acquired introduction token ID, the introduced user ID, and the product ID, thereby determining whether the introduction token has been issued (S9).

[0105] When the reward granting unit 435 determines that the corresponding introduction token has not been issued (NO in S9), it ends the process. On the other hand, when the reward granting unit 435 determines that the corresponding introduction token has been issued (YES in S9), it grants a reward to the introducing user identified by the introduction token (S10).

[0106] [Effects of this embodiment] As described above, when an authentication token corresponding to an introducing user and a product is issued, the information processing device 4 executes a process for issuing an introduction token corresponding to the introducing user, the introduced user, and the product, and executes a process for granting a privilege to the introducing user when a provider of the product corresponding to the introduction token provides the product to the introduced user. In this way, the information processing device 4 issues an introduction token as information indicating the track record of the introducing user introducing the product to the introduced user, thereby preventing the information indicating the track record of the introducing user introducing the product to the introduced user from being deleted or rewritten. As a result, the information processing device 4 can provide a reward to the introducing user.

[0107] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote industry, innovation and infrastructure."
