Description

[[Technical Field]]

[0001] The present invention relates to a technology for providing information to a trader, who is a person intending to conduct a transaction regarding a property usage right that is a usage right for a real estate property. [[Background Art]]

[0002] In recent years, various usage forms for short-term use of real estate have been proposed and realized, in addition to accommodation in accommodation facilities, such as co-owning a villa in a resort area and adjusting the usage period among co-owners, and so-called private lodging where privately-owned real estate is provided as an accommodation facility. Possibly due to the influence of the growing global tourism boom, the number of Japanese travelers and travelers from foreign countries has increased remarkably in Japan, and the demand for accommodation real estate has also increased accordingly. In response to such an increase in demand, the setting of short-term usage rights for real estate, for example, reservation of accommodation facilities, cannot be sufficiently handled by the conventional telephone communication, and reservation systems via web pages and the like using IT technology have been utilized.

[0003] For example, Patent Document 1 discloses a technology that realizes the sale of accommodation facilities by travel agencies on a website installed by the accommodation facility side. In addition, Patent Document 2 discloses a technology for consolidating, on the side of the accommodation facility, reservation information made via a plurality of reservation sites, for managing usage reservations of the accommodation facility.

[0004] [[Patent Document 1]] Japanese Patent No. 6853339 [[Patent Document 2]] Japanese Patent No. 5999225 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] With the growing demand for short-term use of real estate, deregulation is also progressing. For example, in the past, providing real estate to a third party for short-term use required prior permission from the relevant government agency under the Hotel Business Act, but legislative measures have been taken so that in the case of private lodging (although certain conditions are imposed), notification is sufficient.

[0006] In light of these circumstances, it is expected that the secondary market for short-term use rights of real estate will become widespread in the near future. In the case of secondary markets, it is anticipated that both buyers and sellers of use rights may include individuals who do not possess sufficient knowledge of real estate use. For such sellers, it will not be easy to properly disclose the use conditions of the real estate set by the owner, to set appropriate prices, or to avoid selling use rights to problematic buyers. Buyers of use rights will also face problems, such as how much they can trust sellers who are not experts, like travel agents.

[0007] Therefore, in order to facilitate smooth secondary distribution even when sellers and buyers lack specialized knowledge, a system for appropriate distribution management is necessary. However, neither Patent Document 1 nor 2 discloses any such technology.

[0008] This invention has been made in view of the above-mentioned problems, and aims to provide a technology that provides necessary and accurate information to traders who intend to conduct transactions concerning property usage rights, which are rights to use real estate properties.

It goes without saying that any configuration other than the specific configurations shown in the embodiments that produces similar functions and effects is also included in the technical scope of the present invention.

[0018] (Embodiment 1) First, the information provision system according to Embodiment 1 will be described. As shown in Figure 1, the information provision system according to Embodiment 1 comprises: a property information generation unit 1 that generates property information, which is information relating to property usage rights in circulation; a property disclosure condition setting unit 2 that sets property disclosure conditions, which are the disclosure conditions for individual pieces of information included in the generated property information; a trader information generation unit 3 that generates trader information, which is information relating to traders who intend to conduct transactions relating to property usage rights; a trader disclosure condition setting unit 4 that sets trader disclosure conditions, which are the disclosure conditions for individual pieces of information included in the generated trader information; a property token generation unit 5 that generates property tokens, which are non-fungible tokens that correspond to individual properties; a trader token generation unit 6 that generates trader tokens, which are non-fungible tokens that correspond to individual traders; and a transaction information generation unit that generates transaction information stored in blocks in a distributed ledger corresponding to property tokens based on the property information. The system comprises a property transaction generation unit 7 that generates transactions, a trader transaction generation unit 8 that generates transactions to be stored in a distributed ledger block corresponding to a trader token based on trader information, an electronic signature generation unit 9 that generates an electronic signature which is data that proves that the generation and output of information included in the property transaction and trader transaction is in accordance with the intentions of the holder of the property token and trader token, an output unit 10 that outputs the property transaction, trader transaction and the electronic signatures related to each, an information acquisition unit 11 that acquires property information and trader information included in transactions stored in a distributed ledger block, and an information provision unit 12 that provides property information related to the property usage rights to be traded and trader information related to the trading partner to a person who intends to conduct a transaction related to property usage rights.

[0019] The property information generation unit 1 is for generating property information, which is information set for each property usage right that is the subject of information provision in the information provision system according to this embodiment 1, and is related to the property usage right. Specifically, the property information generation unit 1 includes a property structure information generation unit 13 that generates property structure information, which is information about the physical structure of the property that is the subject of the property usage right; a past transaction information generation unit 14 that generates past transaction information, which is information about past transaction details related to the property usage right; a nearby price information generation unit 15 that generates nearby price information, which is information about the price of property usage rights for nearby properties that are located near the property related to the property usage right; a nearby facility information generation unit 16 that generates nearby facility information, which is information about facilities located near the property related to the property usage right; a nearby event information generation unit 17 that generates nearby event information, which is information about events held near the property related to the property usage right; and a sales condition information generation unit 18 that generates sales condition information, which is information about the constraints on the sale of the usage right. The unit has the function of generating property information that includes one or more pieces of information from the property structure information, etc., and outputting it to the property transaction generation unit 7.

[0020] The property structure information generation unit 13 is configured to generate property structure information, which is information about the physical structure of a real estate property that is the object of a circulated property use right. Specifically, the property structure information generation unit 13 has a function of generating information about physical structures such as the property's location, age, size, floor plan, and indoor equipment as the property structure information. In generating the property structure information, information provided by the owner or manager of the property may be used, or information published on the Internet or other platforms may be used. Note that the "property" that is the object of the property use right is a concept including all real estate, but is not limited to real estate in the legal concept. For example, it is a concept that includes one room in an independent real estate (such as a guest room in a hotel) or a partial space in one room, and any whole or part of real estate for which an independent use right is established and becomes the subject of transaction shall fall under the "property" in the present invention. In addition, the property structure information shall be generated and recorded in a form associated with the real estate property itself that is the object of the circulated property use right (that is, generated and recorded in a manner that clarifies which property each piece of property structure information relates to), and this shall also apply to past transaction information or sales condition information.

[0021] The past transaction information generation unit 14 is configured to generate past transaction information, which is information about past transaction contents related to a property use right that is the use right of a property subject to distribution management. Specifically, the past transaction information generation unit 14 has a function of generating past transaction information, which is information including past transaction contents related to the same property, such as transaction date and time, transactors (seller and purchaser of the use right), the use period subject to the transaction, and the transfer price of the use right. In generating the past transaction information, information provided by the owner / manager of the property and / or past transactors may be used, public information may be used, or information about transactions concluded in the past may be recorded in advance and the recorded information may be used.

[0022] The neighboring price information generation unit 15 is configured to generate neighboring price information, which is information relating to usage right prices of other properties located in the neighborhood of a property subject to distribution management. Specifically, the neighboring price information generation unit 15 has a function of generating neighboring price information that is information including information relating to usage right prices of other similar properties located within a certain distance range from neighboring properties, for example, the property subject to distribution management. The neighboring price information is used as reference information when determining the usage right price of a property. Although it is preferable that "other properties" are the same as or similar to the target property in physical structure, properties that differ to a certain extent may also be included in "other properties" to generate the neighboring price information. If the physical structures of the properties are different, correction may be made to the usage right price for a case where the physical structures match (for example, for another property having twice the area of the target property, the usage right price may be corrected to half price before information is generated), or information may be generated in a mode that explicitly indicates differing parts in the physical structure. In addition, as the content of the neighboring price information, a mode may be adopted in which information on the usage right price of each individual other property is included, or information on the usage right price of the target property estimated based on the usage right prices of individual other properties may be included for easy reference. When generating the neighboring price information, information provided by the owners or managers of other neighboring properties or past transactors related to the usage rights of said other properties may be used, public information may be used, or information related to transactions of other properties that have been completed in the past may be recorded in advance, and said recorded information may be used.

[0023] The Neighborhood Facility Information Generation Unit 16 is for generating neighborhood facility information, which is information about tourist facilities and other facilities located near the property subject to distribution management. Specifically, the Neighborhood Facility Information Generation Unit 16 has the function of generating neighborhood facility information, which includes information about facilities such as tourist facilities located within a certain distance from the property subject to distribution management (meaning land or things fixed to the land, including not only buildings but also parks, plazas, etc., and not limited to what is legally defined as real estate or what is subject to property use rights), such as information about the physical structure of the facility, information about how the facility is used, and information about the level of attention it attracts from tourists. When generating neighborhood facility information, information provided by the owner or manager of the facility may be used, or publicly available information such as maps may be used.

[0024] The Neighborhood Event Information Generation Unit 17 is for generating neighborhood event information, which is information about events held in the vicinity of the property subject to distribution management. Specifically, the Neighborhood Event Information Generation Unit 17 has the function of generating neighborhood event information that includes information about events held within a certain distance range from the property subject to distribution management, such as sporting events, music concerts, theatrical events, special exhibitions held for a limited period at museums, summer festivals, fireworks displays, etc. The Neighborhood Event Information Generation Unit 17 does not impose any particular restrictions on the timing of the events in the neighborhood event information it generates, but it is desirable to include information about events that will be held in the future, from the perspective of using it as reference information for future transactions of property usage rights.

[0025] The sales conditions information generation unit 18 is for generating sales conditions information, which is information regarding the constraints on the sale of property usage rights. Specifically, the sales conditions information generation unit 18 has the function of generating sales conditions information, which includes specific sales constraints such as not being able to sell property usage rights at a price lower than the price specified by the property manager, not being able to resell them until a certain period of time has elapsed since the purchase of the usage rights, not being able to sell them to certain attributes (for example, corporations), and only being able to sell them to traders with specified attributes. When generating sales conditions information, it is preferable to utilize information that has been made public or provided by the property owner / manager, as well as information regarding legal regulations.

[0026] The Property Disclosure Condition Setting Unit 2 is for setting property disclosure conditions, which are the disclosure conditions for individual pieces of information included in the generated property information, such as property structure information, past transaction information, neighborhood price information, nearby facility information, nearby event information, and sales conditions information. Specifically, the Property Disclosure Condition Setting Unit 2 has the function of setting property disclosure conditions that specify to what extent and to what degree individual pieces of information will be disclosed depending on the transaction recipient when the Information Provision Unit 12, described later, provides property information. More specifically, the Property Disclosure Condition Setting Unit 2 sets disclosure conditions such as disclosing all of the information to transaction recipients who meet condition A, and disclosing only the nearby event information to transaction recipients who meet condition B, as well as disclosure conditions that restrict the disclosure of some information, such as disclosing only an estimated value, rather than the exact value, of the usage rights price of other properties to transaction recipients who meet condition C. Conditions A, B, C, etc. constitute the property disclosure conditions. Specific examples of property disclosure conditions include, for example, whether the recipient of the information is a paid member of the information provision system according to Embodiment 1, whether the number of property usage rights transactions using the system exceeds a predetermined number, whether the person has previously engaged in problematic behavior such as information leaks, and other attribute information such as the recipient's age, gender, nationality, educational background, and work history.

[0027] The Transaction Information Generation Unit 3 is for generating transaction information, which is information set for each transactionor who intends to conduct a transaction of property usage rights. Specifically, the Transaction Information Generation Unit 3 comprises a Seller Information Generation Unit 19 that generates seller information, which is information when the transactionor acts as the seller of property usage rights, and a Buyer Information Generation Unit 20 that generates buyer information, which is information when the transactionor acts as the buyer of property usage rights. In this invention, "transactionor" is a concept that is not limited to those who have previously traded property usage rights, but also includes those who intend to conduct a transaction for the first time, and includes not only natural persons but also corporations and other entities that can be the subject of a property usage rights transaction. The Transaction Information Generation Unit 3 outputs transaction information, which includes at least one of seller information and buyer information, to the Transaction Transaction Generation Unit 8, and the Transaction Transaction Generation Unit 8 generates a transaction based on the transaction information.

[0028] The seller information generation unit 19 is for generating seller information, which is information about a trader when the trader acts as a seller. Specifically, the seller information generation unit 19 includes a sales activity information generation unit 21 which generates sales activity information, which is information about the trader's activities when the trader is involved in a transaction as a seller of property usage rights; a sales property information generation unit 22 which generates sales property information, which is information about the evaluation of property usage rights sold by the trader as a seller; and a sales evaluation information generation unit 23 which generates sales evaluation information, which is information about the trader's evaluation as a seller. The unit has the function of generating seller information that includes one or more pieces of information from the sales activity information and information about the disclosure method.

[0029] The sales activity information generation unit 21 is for generating sales activity information, which is information about the activities of a trader as a seller. Specifically, the sales activity information generation unit 21 has the function of generating sales activity information such as an overview of the property usage rights sold by the trader, the sales period, the sales price, and the closing rate. When generating sales activity information, information provided by the trader or another trader who negotiated with the trader as a buyer (or potential buyer) may be used, or information on past property usage right transactions may be recorded in advance and this recorded information may be used.

[0030] The Sales Property Information Generation Unit 22 is for generating sales property information, which is information regarding the valuation of the property usage rights themselves that a transactional party handled when acting as a seller. Specifically, the Sales Property Information Generation Unit 22 generates sales property information as information that includes one or more of the following: information regarding the value fluctuation of property usage rights that a transactional party sold or attempted to sell (for example, information regarding the difference between the purchase price and the resale price of the property usage rights when they were purchased from the transactional party and then resold. The higher the resale price compared to the purchase price, the higher the valuation, and the lower the resale price, the lower the valuation), information regarding the level of attention from other transactional parties at the time of the sale of the property usage rights (for example, information regarding the number of other transactional parties that made offers to purchase the property when the transactional party sold it), and valuation information for the property related to the property usage rights (for example, valuation information by transactional parties who purchased the property usage rights and actually used the property). The sales property information may include information about value fluctuations, or it may include numerical information (for example, assigning a score out of 100, or rating it in three stages: A, B, and C) that corresponds to the level of the property's value derived from the information. When generating the sales property information, it may be possible to record information about past transactions of property usage rights in advance and extract information about the property usage rights related to the sale from the recorded information, or to utilize information provided by other parties who transacted with the transaction in question, or by the person who ultimately actually used the property related to the property usage rights.

[0031] The sales evaluation information generation unit 23 is for generating sales evaluation information, which is information regarding the evaluation of the conduct and words of a trader when the trader is acting as a seller.

[0036] The Transaction Disclosure Condition Setting Unit 4 is for setting transaction disclosure conditions, which are the disclosure conditions for individual pieces of information included in the seller information and buyer information that constitute the generated transaction information. Specifically, the Transaction Disclosure Condition Setting Unit 4 has the function of setting transaction disclosure conditions that specify to what extent and to what degree individual pieces of information will be disclosed depending on the transaction recipient when the information provision unit 12, described later, provides transaction information. More specifically, the Transaction Disclosure Condition Setting Unit 4 sets disclosure conditions such as disclosing all of the information to transaction recipients who meet condition A, and disclosing only the sales activity information to transaction recipients who meet condition B, as well as disclosure conditions that restrict the disclosure of some information, such as disclosing only an estimated value, not the exact value, of the price of the property usage rights purchased, for transaction recipients who meet condition C. Conditions A, B, C, etc. are the conditions for disclosing information to the trader. Specific examples of these conditions for disclosing information to the trader include, for example, whether the trader receiving the information is a paid member of the information provision system according to Embodiment 1, whether the number of property usage rights transactions using the system exceeds a predetermined number, whether the person has previously engaged in problematic behavior such as information leaks, and preferably other attribute information such as the trader's age, gender, nationality, educational background, and work history.

[0037] The property token generation unit 5 is for generating property tokens, which are non-fungible tokens that correspond to individual properties. A "non-fungible token" is a so-called NFT (Non-Fungible Token), that is, a token that has the property of being non-fungible with other tokens by possessing unique data, and is issued based on the ERC721 standard of Ethereum®.

[0038] The property tokens generated by the property token generation unit 5 represent the right to use the corresponding property, and the person who holds the right to use the corresponding property holds the property token. Specifically, the person who holds the right to use the property at the time the property token is generated by the property token generation unit 5 holds the property token, and when the right to use the property is transferred through a transaction, etc., the holder of the property token is also transferred accordingly. Furthermore, property transactions generated based on information including property information, which is information about the owner / manager of the property corresponding to the property token and information about the right to use the property, are output and stored in blocks that constitute a distributed ledger on a distributed network that forms a blockchain.

[0039] Blockchain is a technology that uses cryptographic techniques to synchronize data among multiple computers that make up a decentralized network. Specifically, each block is composed of a collection of token information, such as agreed-upon transaction records, and information to connect to other blocks (information from the previous block). A blockchain is formed by linking multiple such blocks together. Even if data is tampered with on some of the computers, the correct data is selected by majority vote among the other computers, making it extremely difficult to destroy or tamper with the data.

[0040] The correspondence between property tokens and properties will be in the form of associating the identifier of the property token with the identification information of the property. While the principle is a one-to-one correspondence between properties and property tokens, it is also possible to associate a group of properties with certain commonalities (for example, multiple different rooms in the same building) with a single property token, and record property information for each of these properties within a block that constitutes the distributed ledger.

[0041] Furthermore, the property token generation may be performed by the property token generation unit 5 itself, or it may be performed by an external system that is directly or indirectly connected to the property token generation unit 5 by issuing a predetermined command to that external system. In addition, the specific format of the property token is not limited to that which conforms to the Ethereum® standard ERC721, but may be any format as long as it has the property of being non-fungible and is stored in a block that constitutes a distributed ledger where the transaction history corresponds to the property token on the decentralized network that forms the blockchain.

[0042] The trader token generation unit 6 is for generating trader tokens, which are non-fungible tokens that have a one-to-one correspondence with individual traders. Trader tokens, like property tokens, are composed of non-fungible tokens that possess unique data and are not interchangeable with other tokens, and are issued, for example, based on the ERC721 standard of Ethereum®. Information including trader information about the trader corresponding to the trader token is stored in the block that constitutes the distributed ledger corresponding to the trader token.

[0043] The property transaction generation unit 7 is for generating property transactions that are stored in blocks in the distributed ledger that correspond to property tokens (i.e., recorded in the distributed ledger). Specifically, the property transaction generation unit 7 has the function of generating information that includes, as the content of a property transaction, information regarding the setting and changing of the ownership name of the property token, as well as property information, which is information about the corresponding property, and information regarding property disclosure conditions, which is the disclosure conditions for the individual pieces of information that make up the property information.

[0044] The trader transaction generation unit 8 is for generating trader transactions that are stored in blocks in the distributed ledger that correspond to the trader token (i.e., recorded in the distributed ledger). Specifically, the trader transaction generation unit 8 has the function of generating information that includes, as the content of the trader transaction, information regarding the setting and changing of the name of the holder of the trader token, as well as trader information, which is information about the corresponding trader, and information regarding trader disclosure conditions, which is the disclosure conditions for the individual pieces of information that make up the trader information. The trader transaction generation unit 8 may generate trader transactions after encrypting this information to a certain extent in order to conceal it, or it may form the distributed ledger to which the output is located on a private blockchain.

[0045] The electronic signature generation unit 9 has the function of generating electronic signatures, which are data that proves that the creation and output of information contained in each property transaction and transaction are in accordance with the intentions of the respective holders of the property token and transaction token. Specifically, the electronic signature generation unit 9 has the function of generating hash values ​​for the property transaction and transaction transaction generated by the property transaction generation unit 7 and transaction transaction generation unit 8, respectively, and then encrypting these hash values ​​with the private keys held by the respective holders of the property token and transaction token to generate electronic signatures. A "hash value" is a fixed-length value obtained by applying a certain calculation procedure to the original data. Since this calculation procedure is irreversible, it is considered impossible to recover the original data from the hash value. A "private key" is a sequence of numbers used in the encryption process and is configured to be decryptable using the corresponding "public key". In this embodiment 1, the property transaction generation unit 7, the trader transaction generation unit 8, and the electronic signature generation unit 9 are configured to create each transaction and the electronic signature related to each transaction themselves. However, the embodiment is not limited to this configuration, and the property transaction generation unit 7, the trader transaction generation unit 8, and the electronic signature generation unit 9 may have the function of only instructing an external device to create each transaction and the electronic signature related to each transaction.

[0046] The output unit 10 outputs property transactions generated by the property transaction generation unit 7 and electronic signatures related to property transactions generated by the electronic signature generation unit 9 to a decentralized network corresponding to the property token, and outputs transaction transactions generated by the transaction transaction generation unit 8 and electronic signatures related to transaction transactions generated by the electronic signature generation unit 9 to a decentralized network corresponding to the transaction token. In this embodiment 1, the output unit 10 is configured to directly output transactions and electronic signatures, but it may also be configured to simply instruct other components (including those provided outside the information provision system according to embodiment 1) to output. In this embodiment 1, the output unit 10 is directly or indirectly connected to the decentralized network and is configured to output predetermined data to the decentralized network. The distributed network generates a hash value for each output transaction and compares it with the data obtained by decrypting the corresponding digital signature with a public key (= transaction hash value). If the two values ​​are different, it is determined that the transaction is not genuine and registration is rejected. If the two values ​​match, it is determined that the transaction is genuine and the information composed of the transaction is stored in a block that constitutes the distributed ledger. The correspondence between each transaction and each distributed ledger can be established, for example, by linking the identification information of the distributed ledger with the identification information of the transaction. More simply, the same information as the identification information of the transaction may be used as the identification information of the distributed ledger. The identification information of the distributed ledger is used when outputting information by the output unit 10, as well as when retrieving information in the information retrieval unit 11.

[0047] The information acquisition unit 11 acquires property information relating to the property usage rights that the trader intends to trade, and trader information relating to other traders who will be the counterparty to the transaction of said property usage rights, from a distributed ledger in which the respective information is recorded, and outputs it to the information provision unit 12. Specifically, the information acquisition unit 11 includes a disclosure condition information acquisition unit 28 that acquires information on the disclosure conditions of the traders to whom the acquired information will be provided, an information access unit 29 that accesses a distributed ledger that stores the information to be acquired, and an information acquisition unit 30 that acquires information from the information stored in the distributed ledger that can be disclosed according to the acquired disclosure conditions.

[0048] The disclosure condition information acquisition unit 28 is for acquiring disclosure condition information, which is information regarding the disclosure conditions of a trader who intends to acquire information. In the information provision system according to this embodiment 1, for example, a trader who intends to purchase a specific property usage right intends to acquire property information related to the property usage right and trader information (more precisely, seller information within the transaction information) related to the trader who holds the property usage right via the information acquisition unit 11. Similarly, a trader who intends to sell a property usage right intends to acquire property information related to the property usage right and trader information (more precisely, buyer information within the transaction information) related to a person who has offered to purchase or a trader who intends to inquire about selling. In these cases, the disclosure condition information acquisition unit 28 has the function of enabling access to the distributed ledger and acquisition of information to the extent that the disclosure conditions are met when acquiring information by acquiring the disclosure condition information of the trader who intends to acquire information. Here, "disclosure conditions" refer to conditions A, B, C, etc., which are disclosure conditions set by the property disclosure condition setting unit 2 and the transactioner disclosure condition setting unit 4. For example, the disclosure condition information acquisition unit 28 acquires disclosure condition information based on whether or not the person is a paid member of the information provision system according to this embodiment 1, whether or not the number of property usage rights transactions using the system is above a predetermined number, whether or not the person has committed problematic behavior such as information leakage in the past, as well as attribute information such as the transactioner's age, gender, nationality, educational background, and work history.

[0049] The information access unit 29 is for accessing a distributed ledger that stores the information that the trader wishes to obtain. Specifically, if the information to be obtained is property information relating to a specific property usage right, the information access unit 29 has the function of accessing the distributed ledger corresponding to the property avatar associated with that property, and if the information to be obtained is trader information relating to a specific trader, it has the function of accessing the distributed ledger corresponding to the trader avatar associated with that trader.

[0050] The information acquisition unit 30 is for acquiring information recorded in the distributed ledger accessed by the information access unit 29. Specifically, the information acquisition unit 30 has the function of selecting information that can be disclosed from the information recorded in the accessed distributed ledger based on the disclosure conditions information of the trader seeking to acquire the information, and acquiring the selected information. In addition, for information that can be partially disclosed depending on the disclosure conditions (for example, only an estimated value can be disclosed for past sales prices of property usage rights, etc.), the information acquisition unit 30 will perform the necessary information processing (calculation of an estimated value, etc.) before acquiring the information.

[0051] The Information Provision Unit 12 is for providing property information and other transaction information obtained by the Information Acquisition Unit 30 to transactionors who have requested information. Specifically, the Information Provision Unit 12 has the function of providing transactionors who have requested information with information obtained by the Information Acquisition Unit 30 that meets the disclosure conditions regarding that transactionor. This allows transactionors, for example, a buyer (or prospective buyer) considering purchasing a particular property usage right, to receive property information regarding that property usage right to consider whether or not to purchase it, and to receive transaction information (more precisely, seller information included in the transaction information) regarding another transactionor who is the owner and seller (or prospective seller) of that property usage right to consider the details of negotiations. Alternatively, a trader, as a seller (or prospective seller) considering selling the property use rights they own, can receive property information regarding those property use rights to understand the constraints on the sale of those property use rights (for example, information regarding the minimum selling price, etc.), receive trader information (more precisely, buyer information included in the trader information) regarding the buyer (or prospective buyer), determine whether the trader is a suitable person to buy, and, if they are a suitable person, consider the content of negotiations with that trader.

[0052] Next, the advantages of the information provision system according to Embodiment 1 will be described. The information provision system according to Embodiment 1 has the function of providing property information, which is information about the property use rights that will be the object of the transaction, to a person who is about to conduct a transaction for property use rights, and also providing transaction information, which is information about another transaction party that will be the other party to the transaction. By providing property information, transaction parties who are about to conduct a transaction can grasp the details of the property use rights that will be the object of the transaction, and if they are involved as a seller, for example it becomes easier to explain the property to the buyer, and it becomes possible to conduct the transaction after appropriately setting the price, etc., based on the sales conditions information, which is a constraint. If the transaction party is someone who is about to be involved in the transaction as a buyer, they can grasp the specific structure of the property related to the property use rights from the property information and grasp the details of past transactions from the past transaction information, and thus estimate the appropriate price of the property use rights.

[0053] Furthermore, by providing information on other trading partners, a trading party intending to conduct a transaction can, for example, if the trading party is involved as a seller, use the purchase activity information to understand what price range of property usage rights the other party has purchased in the past, and use this as reference material for deriving the selling price. They can also use the purchase evaluation information to understand whether the other party has ever delayed payment of purchase price, and if so, whether they are acceptable as a trading partner. If they are acceptable, they can derive a selling price that includes a risk premium. If the trading party is involved as a buyer, they can, for example, use the sales evaluation information to understand whether the other party has caused trouble in past transactions, and judge their suitability as a trading partner. They can also use the sales property information to understand the future fluctuations in the value of the property usage rights to be purchased from that person, such as whether there is an expectation of price increases, and based on this information, they can decide whether or not to purchase the property usage rights.

[0054] Furthermore, the information provision system according to this embodiment 1 employs a configuration in which only the information that is permitted to be disclosed according to the disclosure conditions derived for each information provider is disclosed, from among the individual pieces of information that constitute the recorded property information and transaction information. By adopting such a configuration, it becomes possible to create differences in the range of information that can be obtained between paying users and free users of the system, and to take measures such as significantly restricting the information disclosed to those who have engaged in problematic behavior in the past.

[0055] (Embodiment 2) Next, the information provision system according to Embodiment 2 will be described. In Embodiment 2, components that have the same name and reference numerals as those in Embodiment 1 will perform the same functions as those in Embodiment 1 unless otherwise specified.

[0056] Figure 2 is a schematic diagram showing the configuration of the information provision system according to Embodiment 2. As shown in Figure 2, the information provision system according to Embodiment 2, in addition to the configuration of Embodiment 1, requires that purchase activity information be included in the buyer information that constitutes the trader information, and newly includes a usage right extraction unit 32 that extracts other property usage rights that have information in common with the information regarding property usage rights related to past purchases included in the purchase activity information in the trader information of the trader who is the recipient of information provided by the information provision unit 31, and the information acquisition unit 33 acquires property information related to the property usage rights extracted by the usage right extraction unit 32 and trader information related to the trader who holds the property usage rights (i.e., a trader who can become the seller of the property usage rights), and the information provision unit 31 provides the property information and trader information.

[0057] The usage rights extraction unit 32 has the function of acquiring transaction information concerning the transaction recipients of the information, acquiring information on property usage rights previously purchased that is included in the purchase activity information contained in the acquired transaction information, and acquiring property information related to said property usage rights. In addition, the usage rights extraction unit 32 has the function of extracting other property usage rights that have property information common to the information contained in the acquired property information, and outputting information on the extracted property usage rights and information on the transaction holders who hold said property usage rights (i.e., transaction holders who could become sellers of said property usage rights) to the information acquisition unit 33.

[0058] In the context of "property information that shares commonalities with other property information," "commonality" includes not only cases where property information completely matches each other, but also cases where individual pieces of information constituting the property information match or are similar to each other. Furthermore, since property information consists of a large amount of information, it is not necessary for all information to match or be similar. Cases where a certain percentage or more of the information matches or is similar, or where only certain pieces of information match or are similar, may also be included in the definition of "commonality." For example, cases where the specific structure of the properties is similar, or where events held near the properties are common (e.g., fireworks displays were held near both properties), or where nearby facilities are common (e.g., art museums were located near both properties), will also be considered as "property information with commonalities."

[0059] Next, the advantages of the information provision system according to this second embodiment will be described. The information provision system according to this second embodiment has a configuration that extracts property usage rights that have commonalities with property usage rights previously purchased by the transaction subject to information provision, and provides property information related to the common property usage rights and transaction information related to the transaction that holds the property usage rights. By adopting this configuration, the information provision system according to this second embodiment has the advantage of being able to provide information on other property usage rights that have commonalities with property usage rights previously purchased by the transaction, that is, new property usage rights that are in line with the transaction's preferences, and to present suitable purchase candidates to the transaction, thereby promoting transactions of property usage rights.

[0060] Although the present invention has been described above in terms of Embodiments 1 and 2, the technical scope of the present invention should not be interpreted as being limited to the specific configurations described in the embodiments. Various modifications and applications of the above embodiments are also within the technical scope of the present invention, as long as they can realize the functions of the present invention. For example, the usage rights extraction unit 32 provides information on new property usage rights that are in line with the trader's preferences based on property information relating to property usage rights that the trader has purchased in the past. However, it is also possible to extract other property usage rights based on a broad range of general behavioral history, not just property usage rights that have been purchased in the past (for example, based on a behavioral history that the trader has attended music concerts many times in the past, property usage rights relating to property information that states that a music concert will be held nearby in the nearby event information). Furthermore, if property usage rights are to be extracted based on such behavioral history, the behavioral history may also be grasped based on fungibility tokens issued by other services used by the trader and the corresponding distributed ledger information. [Industrial applicability]
