Description

Management device and management method 【0001】 One aspect of the present disclosure relates to a management device and a management method. 【0002】 Patent Document 1 describes a device that supports more efficient matching between users. For example, in the device described in Patent Document 1, information indicating the relationships between users of a matching service (each user) is generated based on information indicating the related persons related to each user, and an evaluation value for the sociality of the user is generated based on the generated information. 【0003】 Japanese Unexamined Patent Application Publication No. 2024-44551 【0004】 By the way, in the above-described device, it is preferable that a user forms a predetermined relationship (for example, a relationship between lovers) with only one other user, but it was also possible for a user to form a predetermined relationship with a plurality of other users. In this case, it was difficult to prove that the user did not form a predetermined relationship with a plurality of other users. 【0005】 For example, when a user is looking for their lover, it is preferable that the user matches with only one异性 user to become a couple (a predetermined relationship), but it was also possible to match with a plurality of异性 users to become a couple. In this case, even if the user finds their lover, it was difficult to prove that the user or their lover did not engage in double-dealing or infidelity (prove that the user or their lover is honest and clean). 【0006】 An object of one aspect of the present disclosure is to provide a management device and a management method capable of suppressing a user from forming a predetermined relationship with a plurality of other users. 【0007】To achieve the above objective, the apparatus according to the present invention includes: an acquisition unit that acquires first state information indicating the state of an NFT (Non Fungible Token) acquired by a first user in order to join a group in which a user can form a predetermined relationship with other users; second state information indicating the state of an NFT acquired by a second user in order to join the group; and at least one of first relationship information indicating a user who has a predetermined relationship with the first user and second relationship information indicating a user who has a predetermined relationship with the second user; a modification unit that modifies the first state information and the second state information when it is determined that a predetermined relationship exists between the first user and the second user based on at least one of the first relationship information and the second relationship information; and a management unit that prevents the first user and the second user from joining the group when the first state information and the second state information are modified by the modification unit. 【0008】 According to one aspect of this disclosure, it is possible to prevent a user from forming a predetermined relationship with multiple other users. 【0009】 Figure 1 is a diagram showing an example of the functional configuration of a system including a management device according to one embodiment. Figure 2(a) is a diagram illustrating how a user can join a group managed by the management device shown in Figure 1, and Figure 2(b) is a diagram illustrating the process of a user withdrawing from the group. Figure 3(a) is a diagram showing an example of a screen displayed on a user terminal held by a user when the user joins a group managed by the management device shown in Figure 1, and Figure 3(b) is a diagram showing an example of a screen displayed on a user terminal held by the user when the user withdraws from the group. Figure 4 is a flowchart showing an example of a process to prevent a user from joining a group. Figure 5 is a diagram showing an example of the hardware configuration of a management device according to one embodiment of the present disclosure. 【0010】The embodiments described herein will be described in detail below with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference numerals, and redundant descriptions will be omitted. Furthermore, the embodiments described herein in the following description are specific examples of the disclosure and are not limited to these embodiments unless otherwise stated to limit the disclosure. 【0011】 Figure 1 shows an example of a system 100 including a management device 10 according to one embodiment. As shown in Figure 1, the management device 10 is communicated via a network with a plurality of user terminals 1A, 1B used by each of a plurality of users. The network is any communication network, such as a mobile communication network or the Internet. 【0012】 The management device 10 is a device that manages a group of multiple users. The group is a group that exists on the network. Each of the multiple users owns a user terminal 1. The group is a group that users who have purchased an NFT related to the group on the network can join. For example, the group is a DAO (Decentralized Autonomous Organization) managed by the management device 10. A DAO is an organizational form that utilizes blockchain. In a DAO, unlike conventional centralized organizations, participants cooperate with each other to manage the organization. 【0013】As an example, a group is a group (such as a server set up with Discord®) where participating users can communicate with each other via text or voice. The management device 10 or administrator that manages the group grants users who have joined the group the right to join text channels and voice channels set up within the group. Users can then join the channels to which they have been granted the right to join. In this embodiment, the group is managed only by the management device 10 or administrator, but is not limited to this. For example, the group may also be managed by a user who has been granted the authority to act as a group administrator. In this case, the management device 10 or administrator that manages the group can also grant users who have joined the group the authority to act as a group administrator. 【0014】 In this embodiment, a group is a group on a network that can form predetermined relationships with other users, for example, a group that can match users with other users. Users join a group with the aim of forming predetermined relationships with other users. These predetermined relationships include, for example, a romantic relationship (couple) between a user and another user, a marital relationship between a user and another user, and an employer-employee relationship. However, the predetermined relationships are not limited to those mentioned above and may also include a relationship between a company that commissions work and a company that commissions the work, or a relationship related to an exclusive contract between a company and a freelancer. 【0015】 The management device 10 comprises an acquisition unit 11, a modification unit 12, and a management unit 13. The functions of each functional unit of the management device 10 will be described in detail below. 【0016】First, let's explain the process for a user to join the group described above. As a prerequisite, the user purchases the NFTs necessary to join the group by accessing a management server (not shown) that manages the NFT sales service using user terminal 1. The management server stores purchase information indicating the NFTs purchased by the user. The management server sends a URL to join the group to the user terminal 1 of the user who purchased the NFTs, via email or other means. The user accesses the URL received by user terminal 1 and uses user terminal 1 to input identification information to identify the purchased NFTs and the account information (wallet address) that the user used to purchase the NFTs at the management server. For example, the identification information includes the ID of the NFTs purchased by the user. 【0017】 The acquisition unit 11 acquires identification information for identifying the NFT purchased by the user, and account information used by the user to purchase the NFT. For example, the acquisition unit 11 acquires the identification information and account information entered by the user into the user terminal 1 from the user terminal 1. The method for acquiring each piece of information can be implemented using various publicly known technologies. 【0018】 The management unit 13 determines, based on the identification information and account information, that a user has purchased an NFT related to the group, and then allows the user to join the group. Specifically, the management unit 13 obtains purchase information from the management server, indicating the NFT purchased by the user, based on the account information. The management unit 13 then grants the user permission to join the group (authenticates the user) by comparing the obtained purchase information with the identification information obtained by the acquisition unit 11. For example, if the NFT ID included in the identification information matches the NFT ID included in the purchase information, the management unit 13 grants the user permission to join the group, allowing the user to participate. In this case, the user can join the text channel within the group. For example, as shown in Figure 2(a), first user A obtains the right to join group G by purchasing NFT n1. 【0019】Thus, on a network, a group is a group that a user can join if they purchase an NFT. For example, a user joins a group (e.g., a matching DAO) by purchasing an NFT. The user then forms predetermined relationships with other users through events and communication within the group. 【0020】 Next, we will explain the process of preventing a user from joining a group (the process of excluding a user from a group). Specifically, if a user forms a predetermined relationship with another user in the group, the management device 10 will exclude that user and the other user from the group. This allows the management device 10 to prevent the user from forming a predetermined relationship with yet another user. For example, if the predetermined relationship is a romantic relationship between users, the management device 10 can prevent infidelity or cheating within the group. Thus, the predetermined relationship is a one-to-one relationship that a user can form with another user, and a relationship that a user cannot form with any other user besides the one they formed with. 【0021】 The acquisition unit 11 acquires status information indicating the status of the NFT acquired by a user to join the group. The status information includes first status information indicating the status of the NFT acquired by the first user A, shown in Figure 2(b), to join the group, and second status information indicating the status of the NFT acquired by the second user B, also shown in Figure 2(b), to join the group. The status of the NFT is the status of the NFT, and in this embodiment, it is information indicating a state in which a predetermined relationship is not established or a state in which a predetermined relationship has been established. 【0022】Specifically, when a first user A joins the group, the acquisition unit 11 generates first state information by setting the state of the NFT purchased by the first user A to a state where a predetermined relationship is not established. When a second user B joins the group, the acquisition unit 11 generates second state information by setting the state of the NFT purchased by the second user B to a state where a predetermined relationship is not established. The acquisition unit 11 stores the generated first and second state information in a memory or the like (not shown). The acquisition unit 11 retrieves the first and second state information from the memory or the like. The acquisition unit 11 may also change the state of the first state information (information indicating the state of the NFT purchased by the first user A) stored in the user terminal 1A when the first user A joins the group, to a state where the NFT purchased by the first user A is not established. When the second user B joins the group, the acquisition unit 11 may change the state of the second state information (information indicating the state of the NFT purchased by the second user B) stored in the user terminal 1B to a state where a predetermined relationship is not established. 【0023】 The acquisition unit 11 acquires relationship information indicating users who have a predetermined relationship with the user. The status information includes first relationship information indicating users who have a predetermined relationship with the first user A, and second relationship information indicating users who have a predetermined relationship with the second user B. For example, the first relationship information is information indicating users who have been matched with the first user A. The second relationship information is information indicating users who have been matched with the second user B. 【0024】 In the example shown in Figure 2(b), if a predetermined relationship is formed between User A and User B after they have joined Group G (i.e., User A and User B are matched as a couple), User A and User B input to User Terminal 1 that a predetermined relationship has been formed between them. 【0025】For example, User A and User B, who have become a couple, exchange NFT IDs with each other. User A then enters "We have become a couple" into a channel in Group G (for example, the DAO authentication channel). User A then enters User A's NFT ID and User B's NFT ID into the input form displayed on User Terminal 1A. The acquisition unit 11 acquires the information indicating "We have become a couple," User A's NFT ID, and User B's NFT ID as report information (first relationship information) indicating "We have become a couple." 【0026】 Second user B enters "We have become a couple" into the channel in group G. Second user B then enters the NFT ID of first user A and the NFT ID of second user B into the input form displayed on user terminal 1B. Acquisition unit 11 acquires the information indicating "We have become a couple," the NFT ID of first user A, and the NFT ID of second user B as report information (second relationship information) indicating "report of becoming a couple." 【0027】 In this way, when a predetermined relationship is formed between the first user A and the second user B (when a couple is formed), the first user A and the second user B register each other as their partners (lovers) with the management device 10. As a result, the NFT status of the first user A and the second user B becomes a couple status, and the user corresponding to the NFT that has become a couple status is forcibly removed from the group (for example, by DAO's bot determination). 【0028】 The acquisition unit 11 stores the content and statements exchanged between users within a group, associating them with the users. For example, the acquisition unit 11 stores the content of chats written by users in a text channel within a group, along with the date and time the content was written, associating it with the user who wrote it. Users who have access to the text channel can view the conversation log in the text channel by checking the content stored by the acquisition unit 11. 【0029】The modification unit 12 determines whether a predetermined relationship exists between the first user A and the second user B based on at least one of the first relationship information and the second relationship information. Specifically, the modification unit 12 determines whether a predetermined relationship exists between the first user A and the second user B based on both the first relationship information and the second relationship information. For example, the modification unit 12 determines whether the first user A and the second user B are matched based on at least one of the first relationship information and the second relationship information. 【0030】 The modification unit 12 modifies the first state information and the second state information when it determines that a predetermined relationship exists between the first user A and the second user B. Specifically, when the modification unit 12 determines that a predetermined relationship exists between the first user A and the second user B, it modifies the state of the first state information to indicate that the first user A has a predetermined relationship with the second user B, and also modifies the state of the second state information to indicate that the second user B has a predetermined relationship with the first user A. The process of changing the state of the NFT is implemented by various publicly known technologies. 【0031】 In the example shown in Figure 2(b), the modification unit 12 compares the report information relating to the first user A with the report information relating to the second user B. If the combination of NFT IDs included in each report information matches, it determines that a pair of users (first user A and second user B) corresponding to the combination of NFT IDs have matched. If the modification unit 12 determines that first user A and second user B have matched, it changes the NFT status of both first user A and second user B to a state where a couple has been formed (for example, "couple status"). 【0032】 The modification unit 12 may determine whether a predetermined relationship exists between the first user A and the second user B based on only one of the first relationship information and the second relationship information. For example, the modification unit 12 may determine that the first user A and the second user B are matched when it obtains report information relating to the first user A. 【0033】When the first status information and the second status information are changed by the modification unit 12, the management unit 13 prevents the first user A and the second user B from joining the group (excludes the first user A and the second user B from the group). Specifically, first, the management unit 13 automatically identifies the information included in the status information indicating the status of the NFT in which the NFT status has been changed. For example, the management unit 13 identifies that the first status information and the second status information have been changed. 【0034】 Next, the management unit 13 prevents users corresponding to the identified information from joining the group. For example, the management unit 13 prevents first user A and second user B, corresponding to the identified first and second state information, from joining the group. As an example, the management unit 13 forcibly removes first user A and second user B from the group (excludes them). The process of adding or removing users from a group is implemented using various publicly known technologies. 【0035】Figure 3(a) shows the screen displayed to a user who has joined the group, and Figure 3(b) shows the screen displayed to a user who has been forcibly removed from the group. As shown in Figure 3(a), a user who has joined the group can use various communication channels within the group (for example, a channel for self-introductions, a channel for free conversation, a channel for recruiting event participants, a channel for discussing hobbies, a channel for reporting that a couple has formed, a channel for displaying Q&A, and a channel for showing the group's usage rules). Communication in these communication channels is done using text or voice calls between two or more users. On the other hand, as shown in Figure 3(b), a user who has been forcibly removed from the group will no longer be able to use any channels other than those available only to users who have formed a couple (they will no longer be able to access the communication channels). In such channels, a string of text will be displayed expressing gratitude for using the group (Matching DAO), a string of text indicating that the formation of a couple has been verified (for example, "Couple formation verified" or "Congratulations on forming a couple"), and a string of text indicating that the user has been removed from the group as a result. 【0036】 In this way, when a predetermined relationship is formed between a user and another user (a couple is formed), the NFTs of the user and the other user change, and the user and the other user are automatically removed from the group. 【0037】 Next, the processes performed by the management device 10 according to this embodiment will be explained using the flowchart in Figure 4. Figure 4 is a flowchart showing an example of a process that prevents a user from joining a group. 【0038】 First, the management device 10 acquires first state information and second state information, and first relationship information and second relationship information (steps S01 and S02: acquisition steps). Subsequently, the management device 10 determines whether a predetermined relationship exists between the first user A and the second user B (step S03). 【0039】 If the management device 10 determines that a predetermined relationship exists between the first user A and the second user B (step S03: Yes), the first status information and the second status information are changed (step S04). If the management device 10 changes the first status information and the second status information, the first user A and the second user B are prevented from joining the group (step S05). 【0040】 Finally, if the management device 10 determines that no predetermined relationship exists between the first user A and the second user B (step S03: No), or if step S05 is executed, the process of preventing the user from joining the group is terminated. 【0041】 Next, the effects of the management device 10 and management method according to this embodiment will be described. In the management device 10 and management method of this embodiment, if it is determined that a predetermined relationship exists between a first user and a second user based on at least one of the first relationship information and the second relationship information, the first state information and the second state information are changed, and when the first state information and the second state information are changed, the first user and the second user are prevented from joining the group. As a result, when a user who has joined a group first forms a predetermined relationship, that user is prevented from joining the group. As a result, it is possible to suppress a user from forming predetermined relationships with multiple other users. In addition, even when the group is a DAO, it is possible to suppress a user from forming predetermined relationships with multiple other users in the group. 【0042】Further, when it is determined that a predetermined relationship exists between the first user A and the second user B, the change unit 12 may change the state of the first state information so as to indicate that the first user A has a predetermined relationship with the second user B, and change the state of the second state information so as to indicate that the second user B has a predetermined relationship with the first user A. In this case, it is possible to confirm whether or not the first user A has a predetermined relationship with the second user B only by checking the first state information and the second state information. Thereby, based on the first state information and the second state information, it is possible to surely suppress the user from forming a predetermined relationship with a plurality of other users. 【0043】 Further, the group is a group in which a user can match with another user, the first relationship information is information indicating a user who has matched with the first user A, the second relationship information is information indicating a user who has matched with the second user B, and when it is determined that the first user and the second user have matched based on at least one of the first relationship information and the second relationship information, the change unit 12 may change the first state information and the second state information. In this case, when the group is a group in which a user can match with another user, it is possible to suppress the user from matching with a plurality of other users. 【0044】 Further, when it is determined that a predetermined relationship exists between the first user A and the second user B based on both the first relationship information and the second relationship information, the change unit 12 may change the first state information and the second state information. In this case, compared with the case of determining based on only one of the first relationship information and the second relationship information, it is possible to more accurately determine whether or not a predetermined relationship exists between the first user A and the second user B. 【0045】Also, the group may be a group that users can join when they purchase an NFT. In this case, since all users who join the group purchase an NFT, it is possible to reliably reflect that the user has formed a predetermined relationship with other users in the state of the user's NFT. As a result, based on the state of the user's NFT, it is possible to reliably suppress the user from forming a predetermined relationship with a plurality of other users. 【0046】 Also, the acquisition unit 11 acquires identification information for identifying the NFT purchased by the user and account information used by the user for purchasing the NFT, and when the management unit 13 determines based on the identification information and the account information that the user has purchased an NFT related to a group, the management unit 13 may allow the user to join the group. In this case, only the user who has purchased the NFT can be allowed to join the group. 【0047】 Regarding the present disclosure, the management device 10 of the present disclosure has the following configuration. 【0048】 [1] An acquisition unit that acquires at least one of first state information indicating the state of an NFT (Non-Fungible Token) acquired by a first user for the first user to join a group in which a user can form a predetermined relationship with other users on a network, second state information indicating the state of an NFT acquired by a second user to join the group, first relationship information indicating a user having the predetermined relationship with the first user, and second relationship information indicating a user having the predetermined relationship with the second user; A change unit that changes the first state information and the second state information when it is determined that the predetermined relationship exists between the first user and the second user based on at least one of the first relationship information and the second relationship information; and a management unit that prevents the first user and the second user from joining the group when the first state information and the second state information are changed by the change unit. 【0049】[2] The management device according to [1], wherein the modification unit, when it determines that the predetermined relationship exists between the first user and the second user, changes the state of the first state information to indicate that the first user has the predetermined relationship with the second user, and also changes the state of the second state information to indicate that the second user has the predetermined relationship with the first user. 【0050】 [3] The management device according to [1] or [2], wherein the group is a group in which the user can be matched with the other users, the first relationship information is information indicating a user that has been matched with the first user, the second relationship information is information indicating a user that has been matched with the second user, and the modification unit modifies the first status information and the second status information when it determines that the first user and the second user have been matched based on at least one of the first relationship information and the second relationship information. 【0051】 [4] The management device according to any one of [1] to [3], wherein the modification unit modifies the first status information and the second status information when it determines, based on both the first relationship information and the second relationship information, that a predetermined relationship exists between the first user and the second user. 【0052】 [5] The management device according to any one of [1] to [4], wherein the group is a group that the user can join if they purchase the NFT. 【0053】 [6] The management device according to [5], wherein the acquisition unit acquires identification information for identifying the NFT purchased by the user and account information used by the user to purchase the NFT, and the management unit enables the user to join the group based on the identification information and the account information. 【0054】[7] A management method executed by a management device, comprising: an acquisition step of acquiring first state information indicating the state of NFTs acquired by a first user in order to join a group on a network in which a user can form a predetermined relationship with other users; second state information indicating the state of NFTs acquired by a second user in order to join the group; and first relationship information indicating a user with whom the predetermined relationship exists with the first user and second relationship information indicating a user with whom the predetermined relationship exists with the second user; a modification step of modifying the first state information and the second state information when it is determined that the predetermined relationship exists between the first user and the second user based on at least one of the first relationship information and the second relationship information; and a management step of preventing the first user and the second user from joining the group when the first state information and the second state information have been modified by the modification step. 【0055】 [Definitions of Terms, etc.] The block diagrams used in the description of the above embodiments show functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized using one device that is physically or logically coupled, or it may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wired, wireless, etc.).

For example, a functional block (configuration part) that enables transmission is called a transmitting unit or transmitter. In all cases, as mentioned above, the method of implementation is not particularly limited. 【0057】 For example, the management device 10 in one embodiment of the present disclosure may function as a computer that processes the management method of the present disclosure. Figure 5 is a diagram showing an example of the hardware configuration of the management device 10 according to one embodiment of the present disclosure. The management device 10 described above may be physically configured as a computer device including a processor 1001, memory 1002, storage 1003, communication device 1004, input device 1005, output device 1006, bus 1007, etc. 【0058】 In the following explanation, the term "device" can be replaced with "circuit," "device," "unit," etc. The hardware configuration of the management device 10 may include one or more of the devices shown in the figure, or it may be configured to omit some of the devices. 【0059】 Each function in the management device 10 is realized by loading predetermined software (programs) onto hardware such as the processor 1001 and memory 1002, which causes the processor 1001 to perform calculations, control communication by the communication device 1004, and control at least one of data reading and writing in the memory 1002 and storage 1003. 【0060】The processor 1001 controls the entire computer, for example, by running an operating system.

The above-mentioned storage medium may be, for example, a database, server, or other suitable medium including at least one of the memory 1002 and the storage 1003. 【0064】 The communication device 1004 is hardware (transmitting / receiving device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as a network device, network controller, network card, communication module, etc. The communication device 1004 may be configured to include high-frequency switches, duplexers, filters, frequency synthesizers, etc., in order to implement at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the modification unit 12 described above may be implemented by the communication device 1004. The communication device 1004 may be implemented with physically or logically separated transmitting and receiving units. 【0065】 The input device 1005 is an input device that accepts input from an external source (e.g., a keyboard, mouse, microphone, switch, button, sensor, etc.). The output device 1006 is an output device that outputs to an external source (e.g., a display, speaker, LED lamp, etc.). The input device 1005 and the output device 1006 may be configured as an integrated unit (e.g., a touch panel). 【0066】Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or different buses may be configured for each device. 【0067】 Furthermore, the management device 10 may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), and an FPGA (Field Programmable Gate Array), and some or all of each functional block may be realized by such hardware.
