[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, such descriptions should not be interpreted in a limiting sense, and do not limit the subject matter described in the claims. Furthermore, various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present disclosure. Furthermore, different embodiments can be combined as appropriate.

[0009] [Information Processing System 100 in the First Embodiment] First, a description will be given of an example of the configuration of an information processing system 100 according to the first embodiment. Fig. 1 is a diagram illustrating an example of the configuration of an information processing system 100 according to the first embodiment.

[0010] 1, the information processing system 100 includes, for example, an information processing device 1 and an operation terminal 3. The information processing device 1 and the operation terminal 3 are accessible to each other via a network NW such as the Internet.

[0011] The information processing device 1 is, for example, a physical machine or a virtual machine. The information processing device 1 performs, for example, a process (hereinafter also referred to as information management process) for managing the use of products by each target person 2. Note that the information processing device 1 may be, for example, an information processing device that constitutes at least a part of a cloud system (not shown).

[0012] The operation terminal 3 is, for example, a mobile terminal such as a PC (Personal Computer) or a smartphone, and is a terminal used by each subject 2 when inputting necessary information to the information processing device 1. Specifically, the operation terminal 3 is, for example, a terminal owned by the subject 2. Note that the example shown in FIG. 1 illustrates a case where three subjects 2 (subject 2a, subject 2b, and subject 2c) input necessary information to the information processing device 1 via the operation terminals 3 (operation terminal 3a, operation terminal 3b, and operation terminal 3c), but a number of subjects 2 other than three may input necessary information via the operation terminals 3.

[0013] Specifically, the information processing device 1 manages, for example, information regarding a specific product (hereinafter also simply referred to as a specific product) owned by a specific target person 2 (hereinafter also referred to as a first target person 2) by storing it in the memory unit 130.

[0014] More specifically, the information processing device 1 acquires, for example, request information (hereinafter also simply referred to as request information) requesting use of a specific product by another target person 2 (hereinafter also referred to as second target person 2). After that, for example, in response to acquiring the request information, the information processing device 1 stores information indicating that the specific product is available to the other target person 2 in the storage unit 130.

[0015] That is, the information processing device 1 in this embodiment manages, for example, information indicating the target person 2 who owns each product and information indicating the target person 2 who uses each product as separate information.

[0016] As a result, the information processing device 1 in this embodiment can manage each product in a manner that reflects the situation even if the target person 2 who owns the product is different from the target person 2 who uses the product. Therefore, the information processing device 1 in this embodiment can manage each product in accordance with various usage patterns, for example.

[0017] [Hardware configuration of information processing system] Next, a description will be given of the hardware configuration of the information processing system 10. Fig. 2 is a diagram illustrating the hardware configuration of the information processing device 1 in the first embodiment.

[0018] 2, the information processing device 1 includes a CPU 101, which is a processor, a memory 102, a communication device 103, a storage medium 104, and an output device 105. Each unit is connected to one another via a bus 106.

[0019] The storage medium 104 has, for example, a program storage area (not shown) that stores a program 110 for performing information management processing. The storage medium 104 also has, for example, a storage unit 130 (hereinafter also referred to as a first storage unit 130 or an information storage area 130) that stores information used when performing information management processing. The storage medium 104 may be, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

[0020] The CPU 101 performs information management processing by executing a program 110 loaded from the storage medium 104 to the memory 102, for example.

[0021] The communication device 103 accesses each of the operation terminals 3 via a network NW such as the Internet, for example.

[0022] The output device 105 is, for example, a display, and outputs the results of the information management processing performed by the CPU 101.

[0023] [Functions of information processing systems] Next, a description will be given of the functions of the information processing system 10. Fig. 3 is a block diagram of the functions of the information processing device 1 in the first embodiment. Below, a description will be given of the case where the owner of a specific product (first target person 2) is target person 2a.

[0024] As shown in FIG. 3, the information processing device 1 realizes various functions including an information acquisition unit 111, an information management unit 112, an information determination unit 113, and an information output unit 114 by organically cooperating with hardware such as a CPU 101 and a memory 102 and a program.

[0025] Furthermore, the information processing device 1 stores, for example, management information DT1 in the information storage area 130 as shown in FIG.

[0026] The information acquisition unit 111 acquires, for example, request information requesting the second target person 2 to use a specific product (hereinafter also referred to as first request information).

[0027] Specifically, the subject 2b inputs the first request information to the operation terminal 3b of the subject 2b, for example. Then, the operation terminal 3b transmits the input first request information to the information processing device 1, for example. After that, the information acquisition unit 111 receives the first request information transmitted from the operation terminal 3b, for example.

[0028] For example, in response to the information acquisition unit 111 acquiring the first request information, the information management unit 112 generates management information DT1 indicating that a specific product is available to the second target person 2. Then, the information management unit 112 stores the generated management information DT1 in the information storage area 130, for example.

[0029] Specifically, for example, in response to the information acquisition unit 111 acquiring the first request information, the information output unit 114 outputs the acquired first request information. Then, for example, the information acquisition unit 111 acquires consent information (hereinafter also referred to as first consent information) indicating consent to the output first request information. Thereafter, for example, in response to acquiring the first consent information, the information management unit 112 stores management information DT1 indicating that the second target person 2 can use a specific product in the information storage area 130.

[0030] More specifically, the information determination unit 113, for example, refers to the management information DT1 stored in the information storage area 130, and identifies the target person 2a as the owner of the specific product corresponding to the first request information received by the information acquisition unit 111. Then, the information output unit 114, for example, transmits the first request information received by the information acquisition unit 111 (at least a part of the information included in the first request information) to the operation terminal 3a of the identified target person 2a. Thereafter, the operation terminal 3a outputs the first request information received from the information processing device 1 to, for example, an output device (not shown) of the operation terminal 3a.

[0031] Then, the target person 2a, for example, refers to (views) the first request information output to the output device of the operation terminal 3a, and determines whether or not to accept the first request information (whether or not to permit the target person 2b to use the specific product). As a result, if the target person 2a determines to accept the first request information, the target person 2a inputs, for example, first consent information indicating consent to the first request information (permission of the target person 2b to use the specific product) into the operation terminal 3a. On the other hand, if the target person 2a determines not to accept the first request information, the target person 2a inputs, for example, information indicating not consent to the first request information (not permitting the target person 2b to use the specific product) (hereinafter also referred to as non-consent information) into the operation terminal 3a.

[0032] Next, for example, when first consent information is input by the target person 2a, the operation terminal 3a transmits the input first consent information to the information processing device 1. Then, for example, the information acquisition unit 111 receives the first consent information transmitted from the operation terminal 3a. Thereafter, for example, in response to the information acquisition unit 111 receiving the first consent information, the information management unit 112 generates management information DT1 indicating that a specific product is available to the target person 2b. Then, for example, the information management unit 112 stores the generated management information DT in the information storage area 130.

[0033] That is, in this case, the information management unit 112 generates management information DT1 indicating, for example, that the owner of a specific product is the target person 2a, while the user of the specific product is the target person 2b, and stores the management information DT1 in the information storage area 130.

[0034] In this case, the information management unit 112 may generate management information DT1 including, for example, information indicating that a specific product is owned by a target person 2a and information indicating that a specific product is available to a target person 2b. Below, a description will be given of a case where the management information DT1 includes information indicating a target person 2 who owns each product 11 and information indicating a target person 2 who can use each product 11.

[0035] Furthermore, even when non-consent information is input by the subject 2a, the operating terminal 3a may transmit the input non-consent information to the information processing device 1. The information management unit 112 may generate management information DT1 that also includes the non-consent information transmitted from the operating terminal 3a, and store the generated management information DT1 in the information storage area 130.

[0036] [Information Management Processing in the First Embodiment] Next, the information management process in the first embodiment will be described. Fig. 4 is a flowchart illustrating the information management process in the first embodiment. Fig. 5 to Fig. 8 are diagrams illustrating the information management process in the first embodiment.

[0037] [Specific examples of the correspondence between subject 2 and each product 11] First, a specific example of the correspondence between the subject 2 and the product 11 will be described. Fig. 5 is a diagram illustrating a specific example of the correspondence between the subject 2 and the product 11. The product 11 may be, for example, a ceramic filtration membrane used in a water purification plant. The product 11 may also be, for example, a battery installed in a vehicle.

[0038] In the example shown in FIG. 5, the subject 2a owns, for example, a product 11a. In this case, for example, an NFT (Non-Fungible Token) 12a indicating that the subject 2a owns the product 11a is stored on the blockchain. That is, in this case, for example, the NFT 12a that has been subjected to tamper-proof processing is stored in a storage device (not shown) that forms the blockchain. Hereinafter, the storage device that forms the blockchain will also be referred to as a second storage unit. Also, in the example shown in FIG. 5, for example, the product 11a is stored in a facility 4a owned by the subject 2a. In other words, in the example shown in FIG. 5, the product 11a is, for example, available for use by the subject 2a. Note that, for example, products other than the product 11a are also stored in the facility 4a.

[0039] Also, in the example shown in FIG. 5, subject 2b owns, for example, product 11b. In this case, for example, NFT 12b indicating that subject 2b owns product 11b is stored on the blockchain. That is, in this case, for example, NFT 12b in a state in which tampering prevention processing has been applied is stored in the storage device forming the blockchain. Also, in the example shown in FIG. 5, for example, product 11b is stored in facility 4b owned by subject 2b. In other words, in the example shown in FIG. 5, product 11b is in a state in which it can be used by subject 2b, for example.

[0040] 5, for example, the target person 2a is in a state of owning the product 11a and being able to use the product 11a, and the target person 2b is in a state of owning the product 11b and being able to use the product 11b.

[0041] [Example of management information DT1] Next, a specific example of management information DT1 showing the correspondence between each target person 2 and each product 11 will be described. Fig. 6 is a diagram for explaining a specific example of management information DT1. Specifically, the management information DT1 shown in Fig. 6 is, for example, management information DT1 corresponding to the state shown in Fig. 5.

[0042] The management information DT1 shown in Figure 6 has, for example, the following items: "product identification information" in which identification information for each product 11 is set, "owner" in which information indicating the target person 2 who owns each product 11 is set, and "user" in which information indicating the target person 2 who can use each product 11 is set.

[0043] Specifically, in the information in the first line of the management information DT1 shown in Figure 6, for example, "11a" indicating product 11a is set as the "product identification information," "2a" indicating target person 2a is set as the "owner," and "2a" indicating target person 2a is set as the "user."

[0044] In addition, in the information in the second row of the management information DT1 shown in Figure 6, for example, "11b" indicating product 11b is set as the "product identification information," "2b" indicating target person 2b is set as the "owner," and "2b" indicating target person 2b is set as the "user."

[0045] [Flowchart of information management processing in the first embodiment] Next, a flowchart of the information management process in the first embodiment will be described.

[0046] As shown in FIG. 4, the information acquisition unit 111 waits until it receives, for example, first request information requesting the use of each product 11 from the operation terminal 3 of each target person 2 (NO in step S11 in FIG. 4).

[0047] Then, for example, when first request information regarding a specific product 11 owned by a specific target person 2 is received from the operation terminal 3 of another target person 2 (YES in step S11 of Figure 4), the information determination unit 113 identifies the destination of the received first request information (step S12 of Figure 4).

[0048] Specifically, in the information in the second row of the management information DT1 described in Fig. 6, for example, "11a" is set as the "product identification information" and "2a" is set as the "owner." Therefore, for example, when first request information requesting the use of product 11a is received in step S11, the information determination unit 113 refers to the management information DT1 described in Fig. 6 and identifies target person 2a as the target person 2 who owns the product 11 corresponding to the first request information received in step S11. In other words, in this case, the information determination unit 113 identifies, for example, the operation terminal 3a of target person 2a as the destination of the first request information received in step S11.

[0049] The management information DT1 may include, for example, information that associates each subject 2 with the operation terminal 3 owned by that subject 2. In this case, the information determination unit 113 may, for example, refer to the management information DT1 stored in the information storage area 130 to identify the operation terminal 3a of the subject 2a as the destination of the first request information received in step S11.

[0050] Thereafter, the information output unit 114 transmits, for example, the first request information received in step S11 to the destination (the operation terminal 3 of the specific target person 2) identified in step S12 (step S13 in FIG. 4).

[0051] Specifically, for example, if first request information requesting the use of product 11a is received in step S11 and the destination identified in step S13 is the operation terminal 3a of the target person 2a, the information output unit 114 transmits the first request information received in step S11 to the operation terminal 3a of the target person 2a.

[0052] Next, the information acquisition unit 111 waits, for example, until first consent information in response to the first request information transmitted in step S13 is received from the operation terminal 3 of the specific target person 2 (step S14 in FIG. 4).

[0053] Then, for example, when first consent information is received from the operation terminal 3 of a specific target person 2 (YES in step S14 of FIG. 4), the information management unit 112 stores, for example, management information DT1 indicating information that the specific product is available to other target people 2 in the information storage area 130 (step S15 of FIG. 4). That is, in this case, the information acquisition unit 111 updates, for example, the management information DT1 stored in the information storage area 130.

[0054] Specifically, the example shown in Fig. 7 shows a state in which, for example, after the state shown in Fig. 5, the target person 2a agrees to the target person 2b's use of the product 11a, and the product 11a is transported from the facility 4a to the facility 4b. Therefore, in this case, the information management unit 112 updates the management information DT1 to indicate that the target person 2a continues to own the product 11a and that the target person 2b can use the product 11a, as shown in Fig. 8.

[0055] More specifically, in this case, the information management unit 112 updates the management information DT1 to indicate that the target person 2b can use the product 11a, as shown in the underlined portion of the first line in FIG.

[0056] On the other hand, for example, if the information output unit 114 does not receive the first consent information from the operation terminal 3 of the specific target person 2 within a predetermined time period after sending the first request information in step S13 (NO in step S14 in Figure 4), the information management unit 112 does not perform step S15.

[0057] That is, in this case, the information management unit 112 determines that the specific target person 2 has not given consent for the other target person 2 to use the specific product 11, and does not perform step S15.

[0058] For example, when each target person 2 owns one product 11, he / she can use that one product 11. Specifically, when each target person 2 owns one product 11, he / she can use not only the product 11 that he / she does not own, but also the product 11 that he / she does not own, but he / she cannot use two or more products 11 at the same time.

[0059] Therefore, as shown in Figures 7 and 8, when the information management unit 112 updates the management information DT1 to indicate that the target person 2b uses the product 11a, the information management unit 112 may also update the management information DT1 so that the target person 2 who uses the product 11b is other than the target person 2b.

[0060] Specifically, the example shown in Fig. 7 shows a state in which, after the state shown in Fig. 5, the target person 2b agrees to the target person 2a's use of the product 11b, and the product 11b is transported from the facility 4b to the facility 4a. Therefore, in this case, the information management unit 112 may update the management information DT1 to indicate that the target person 2b continues to own the product 11b and that the target person 2a can use the product 11b, as shown in Fig. 8.

[0061] More specifically, in this case, the information management unit 112 may update the management information DT1 to indicate, for example, that the target person 2a uses the product 11b, as shown in the underlined part of the second line in Figure 8.

[0062] Furthermore, for example, when the information output unit 114 receives the first consent information from the operation terminal 3a of the target person 2a, the information output unit 114 may output an instruction to a predetermined transport company (hereinafter simply referred to as the transport company) to transport the product 11a stored in the facility 4a to the facility 4b. Specifically, in this case, the information output unit 114 may transmit, for example, an instruction to transport the product 11a from the facility 4a to the facility 4b to the operation terminal (not shown) of the transport company.

[0063] In this way, the information processing device 1 in this embodiment acquires, for example, first request information requesting the use of a specific product 11 by the second target person 2. Then, in response to acquiring the first request information, the information processing device 1 in this embodiment stores, in the information storage area 130, management information DT1 indicating that the specific product 11 is available to the second target person 2, for example.

[0064] Specifically, the information processing device 1 in this embodiment, for example, outputs the acquired first request information in response to acquiring the first request information. Then, the information processing device 1 in this embodiment, for example, acquires first consent information indicating consent to the output first request information. Thereafter, the information processing device 1 in this embodiment, for example, stores management information DT1 indicating that the second target person 2 can use the specific product 11 in the information storage area 130 in response to acquiring the first consent information.

[0065] Furthermore, in this embodiment, information indicating that first target person 2 owns specific product 11 is processed to prevent tampering before being stored in a storage device (a storage device forming a blockchain).

[0066] That is, the information processing device 1 in this embodiment manages, for example, information indicating a person who owns each product 11 and information indicating a person who uses each product 11 in a manner that associates them as separate information.

[0067] As a result, the information processing device 1 in this embodiment can manage the products 11 in a manner that reflects this state, even if the target person 2 who owns each product 11 is different from the target person 2 who uses each product 11. Therefore, the information processing device 1 in this embodiment can manage the products 11 in accordance with various usage patterns, for example.

[0068] In the above example, a case has been described in which information about the target person 2 (owner) who owns each product 11 is converted into an NFT and stored in a storage device, and information about the target person 2 (user) who can use each product is stored as management information DT1 in the information storage area 130, but this is not limiting. Specifically, in this embodiment, for example, in addition to information about the target person 2 who owns each product 11, information about the target person 2 who can use each product 11 may also be converted into an NFT and stored in a storage device. Also, in this embodiment, for example, information about the target person 2 who owns each product 11 and information about the target person 2 who can use each product 11 may each be converted into an NFT and stored in a storage device, and stored in the information storage area 130 as management information DT1.

[0069] [Specific example of information management processing (1)] Next, another specific example (hereinafter also referred to as the first specific example) of the information management process in the first embodiment will be described. Figures 9 to 12 are diagrams explaining the first specific example of the information management process in the first embodiment. Note that hereinafter, a description of the process of storing NFTs 12 in a storage device that forms a blockchain will be omitted.

[0070] The examples shown in Figures 9 to 12 are specific examples of a case where, for example, after the state described in Figure 5, the target person 2b requests the target person 2a to exchange the product 11. That is, the examples shown in Figures 9 to 12 are specific examples of a case where, for example, after the state described in Figure 5, the target person 2b transmits, via the operation terminal 3b of the target person 2b, information requesting the target person 2a to purchase the product 11b (for example, the old product 11) (hereinafter also referred to as purchase request information) and information requesting the target person 2a to sell the product 11a (for example, the new product 11) (hereinafter also referred to as sale request information).

[0071] Specifically, for example, when purchase request information for product 11b for target person 2a and sale request information for product 11a for target person 2a are received from operation terminal 3b, information determination unit 113 identifies target person 2a to whom the received purchase request information and sale request information are to be sent (steps S11 and S12 of Figure 4).

[0072] Then, the information output unit 114 transmits the received purchase request information and sale request information to, for example, the operation terminal 3a of the identified target person 2a (step S13 in FIG. 4).

[0073] Next, the information acquisition unit 111 receives, for example, consent information for the transmitted purchase request information and sale request information from the operation terminal 3a (step S14 in FIG. 4).

[0074] Then, for example, the information management unit 112 stores management information DT1 in the information storage area 130, the management information DT1 including information indicating that the subject 2b owns the product 11a and information indicating that the subject 2a owns the product 11b (step S15 in Figure 4).

[0075] Specifically, the example shown in Fig. 9 shows a state in which, for example, after the state shown in Fig. 5, target person 2a purchases product 11b from target person 2b and target person 2a sells product 11a to target person 2b. Therefore, in this case, the information management unit 112 generates management information DT1 indicating, for example, that the owner of product 11a is target person 2b and the owner of product 11b is target person 2a, as shown in the underlined portion of Fig. 10, and stores the generated management information DT1 in the information storage area 130.

[0076] Here, even if the target person 2b sells the product 11b and purchases the product 11a, for example, there are cases where the target person 2b wishes to continue using the product 11b.

[0077] Specifically, for example, if there is still some time left in the service life of product 11b and target person 2a does not wish to use product 11b after purchasing product 11b, target person 2b may wish to continue using product 11b until the number of years of use of product 11b reaches the service life of product 11b.

[0078] Therefore, as shown in Figure 9, even if target person 2a and target person 2b sell product 11b and purchase product 11a, they may not immediately transport product 11a to facility 4b and product 11b to facility 4a.

[0079] Furthermore, as shown in the underlined parts of Figures 9 and 10, even if, for example, the owner of product 11a becomes target person 2b and the owner of product 11b becomes target person 2a, the information management unit 112 may keep the user of product 11a as target person 2a and the user of product 11b as target person 2b in the management information DT1.

[0080] Thereafter, as shown in FIG. 11, for example, after the period agreed upon between the subject 2a and the subject 2b has elapsed and the product 11a has been transported to the facility 4b and the product 11b has been transported to the facility 4a, the information management unit 112 may generate management information DT1 indicating that the user of the product 11a is the subject 2b and the owner of the product 11b is the subject 2a, as shown in the underlined part of FIG. 12, and store the generated management information DT1 in the information storage area 130 (step S15 of FIG. 4).

[0081] In this way, the information processing device 1 in this embodiment acquires, for example, sales request information (hereinafter also referred to as second request information) requesting the sale of product 11a (specific product 11) to target person 2b (hereinafter also referred to as third target person 2), acceptance information (hereinafter also referred to as second acceptance information) indicating acceptance of the second request information, purchase request information (hereinafter also referred to as third request information) requesting the purchase by target person 2a (first target person 2) of product 11b (another product 11) owned by target person 2b, and acceptance information (hereinafter also referred to as third acceptance information) indicating acceptance of the third request information. Then, in response to acquiring the second request information, the second consent information, the third request information, and the third consent information, the information processing device 1 in this embodiment stores management information DT1 in the information storage area 13, the management information DT1 including information indicating that the subject 2b owns the product 11a, information indicating that the subject 2a owns the product 11b, information indicating that the subject 2a can use the product 11a, and information indicating that the subject 2b can use the product 11b.

[0082] As a result, the information processing device 1 in this embodiment can manage the product 11 in a manner that reflects this state, even if the target person 2 who owns the product 11 is different from the target person 2 who uses the product 11.

[0083] Therefore, the information processing device 1 in this embodiment makes it possible, for example, to set the time when each product 11 is bought and sold to be different from the time when transportation, construction, etc. associated with the exchange of each product 11 is carried out.

[0084] Furthermore, as shown in Figures 9 to 12, for example, the target person 2b can store the product 11b at facility 4a even after purchasing the product 11b, thereby reducing the costs required for storing the product 11b (storage at facility 4b).

[0085] Furthermore, as shown in Figures 9 to 12, when target person 2b purchases product 11b from target person 2a, he or she can also sell product 11a, thereby reducing the cost of purchasing product 11b.

[0086] In addition, the target person 2a may guarantee that the quality and functionality of the product 11b will be equivalent to that of the product 11a, for example, after the target person 2b purchases the product 11a and until the target person 2b begins using the product 11a.

[0087] [Specific example of information management processing (2)] Next, another specific example (hereinafter also referred to as a second specific example) of the information management process in the first embodiment will be described. Figures 13 to 16 are diagrams illustrating the second specific example of the information management process in the first embodiment.

[0088] The examples shown in Figures 13 to 16 are specific examples of a case where, for example, after the state described in Figure 9 and before the state described in Figure 11, target person 2c requests target person 2a to purchase product 11b (product 11a that target person 2a purchased from target person 2b), i.e., a case where target person 2c's operation terminal 3c sends sales request information requesting target person 2a to sell product 11b.

[0089] Specifically, when the information determination unit 113 receives, for example, a request to sell product 11b to a target person 2a from the operation terminal 3c of the target person 2c, it identifies the target person 2a to whom the received request to sell information is to be sent (steps S11 and S12 of Figure 4).

[0090] Then, the information output unit 114 transmits the sale request information to, for example, the operation terminal 3a of the identified target person 2a (step S13 in FIG. 4).

[0091] Next, the information acquisition unit 111 receives, for example, consent information for the transmitted sale request information from the operation terminal 3a of the target person 2a (step S14 in FIG. 4).

[0092] Here, as shown in FIG. 13, if the product 11b corresponding to the sales request information received in step S11 is being used by another target person 2 (target person 2b), target person 2c may not be able to use the product 11b, for example, until target person 2b finishes using the product 11b.

[0093] Therefore, in this case, the target person 2a may allow the target person 2c to use the product 11a (the product 11a used by the target person 2a) sold to the target person 2b instead of the product 11b, for example.

[0094] Specifically, in this case, the information output unit 114 may transmit, for example, request information requesting that the target person 2c use the product 11a to the operation terminal 3b of the target person 2b.

[0095] For example, when the information acquisition unit 111 receives consent information for the request information from the operation terminal 3b of the target person 2b, the information management unit 112 may generate management information DT1 indicating that the user of the product 11a is the target person 2c, and store the generated management information DT1 in the information storage area 130.

[0096] That is, as shown in FIG. 13, for example, after the product 11a is transported to facility 4c (facility 4c owned by subject 2c), the information management unit 112 may generate management information DT1 indicating that the owner of product 11b is subject 2c and the user of product 11a is subject 2c, as shown in the underlined part of FIG. 14, and store the generated management information DT1 in the information storage area 130 (step S15 of FIG. 4).

[0097] Thereafter, as shown in FIG. 15, for example, after the period agreed upon between subject 2b and subject 2c has elapsed and product 11a has been transported to facility 4b and product 11b has been transported to facility 4c, the information management unit 112 stores management information DT1 indicating that the user of product 11a is subject 2b and the owner of product 11b is subject 2c in the information storage area 130, as shown in the underlined part of FIG. 16 (step S15 of FIG. 4).

[0098] In this way, the information processing device 1 in this embodiment acquires, for example, sale request information (hereinafter also referred to as fourth request information) requesting the sale of product 11b to target person 2c (hereinafter also referred to as fourth target person 2), and consent information (hereinafter also referred to as fourth consent information) indicating consent to the fourth request information. Then, in response to acquiring the fourth request information and the fourth consent information, the information processing device 1 in this embodiment stores in the information storage area 130 management information DT1 including information indicating that target person 2c owns product 11b and information indicating that target person 2c can use product 11a.

[0099] This allows the target person 2a to effectively utilize the product 11a that has been sold to the target person 2b and is stored in the facility 4a, for example.

[0100] [Specific example of information management processing (3)] Next, another specific example (hereinafter also referred to as a third specific example) of the information management process in the first embodiment will be described. Figure 17 is a diagram illustrating the third specific example of the information management process in the first embodiment. Hereinafter, notation of the NFTs 12 corresponding to each product 11 will be omitted.

[0101] As shown in FIG. 17, even if subject 2a sells product 11c (e.g., product 11 stored in facility 4a) to subject 2b, subject 2a may transport product 11d (e.g., product 11 stored in facility 4c owned by subject 2a) different from product 11c to facility 4b and allow subject 2b to use product 11d.

[0102] In this case, the information management unit 112 may store management information DT1 in the information storage area 130, which indicates that the owner of product 11c is the target person 2b and that the user of product 11d is the target person 2b.

[0103] As a result, the information processing device 1 in this embodiment can manage this situation even when, for example, it is difficult to transport product 11c from facility 4a to facility 4b and product 11d is transported from facility 4c to facility 4b instead of product 11c.

[0104] In addition, the target person 2a may guarantee that the quality and functionality of the product 11d will be equivalent to that of the product 11c, for example, after the target person 2b purchases the product 11c and until the target person 2b begins using the product 11c.

[0105] [Specific example of information management processing (4)] Next, another specific example (hereinafter also referred to as a fourth specific example) of the information management process in the first embodiment will be described. Figures 18 to 20 are diagrams illustrating the fourth specific example of the information management process in the first embodiment.

[0106] As shown in FIG. 18, for example, if product 11e owned by subject 2b or product 11f owned by subject 2c is a product 11 that requires maintenance (e.g., a battery that needs to be charged at facility 4a), subject 2a may appropriately exchange each product 11 owned by each subject 2 with each product 11 owned by subject 2a (e.g., product 11g), and perform maintenance on each product 11 owned by each subject 2.

[0107] Specifically, as shown in FIG. 19, for example, when subject 2a receives request information from operation terminal 3b of subject 2b requesting that maintenance be performed on product 11e, subject 2a may exchange product 11g stored in facility 4a for product 11e stored in facility 4b and then perform maintenance on product 11e.

[0108] In this case, the information management unit 112 may store management information DT1 in the information storage area 130, which indicates that the user of product 11e is target person 2a and the user of product 11g is target person 2b, for example.

[0109] Thereafter, as shown in FIG. 20, for example, when subject 2a receives request information from operation terminal 3c of subject 2c requesting that maintenance be performed on product 11f, subject 2a may exchange product 11e stored in facility 4a (product 11e for which maintenance has been completed) for product 11f stored in facility 4d owned by subject 2c, and then perform maintenance on product 11f.

[0110] In this case, the information management unit 112 may store management information DT1 in the information storage area 130, which indicates that the user of product 11f is target person 2a and the user of product 11e is target person 2c, for example.

[0111] As a result, the information processing device 1 in this embodiment can manage the product 11 in a manner that reflects this situation, even if, for example, the target person 2 who owns each product 11 is different from the target person 2 who uses each product 11 and there is no need for each product 11 to be used by its owner.

[0112] As shown in FIG. 19, when subject 2b uses product 11g, subject 2a may, for example, guarantee that the quality and functionality of product 11g are equivalent to those of product 11e (product 11 owned by subject 2b).

[0113] In this case, the target person 2a may determine the usage fee for the product 11g according to the difference in performance between the product 11e and the product 11g, for example.

[0114] Specifically, for example, if product 11e and product 11g are batteries and the chargeable amount of product 11g is greater than the chargeable amount of product 11e, in other words, if product 11g has higher performance than product 11e, the usage fee for product 11g may be set higher than when the chargeable amount of product 11g is equal to the chargeable amount of product 11e.

[0115] Furthermore, for example, if product 11e and product 11g are batteries and the chargeable amount of product 11g is less than the chargeable amount of product 11e, in other words, if product 11e has higher performance than product 11g, the usage fee for product 11g may be set lower than when the chargeable amount of product 11g is equal to the chargeable amount of product 11e.
