Abstract
Description
Technical Field
[0001] The present invention relates to a technology for providing information to a trader who intends to conduct a transaction regarding the right to use a real estate property, which is the right to use the property.
Background Art
[0002] In recent years, regarding the short-term use of real estate, in addition to staying at accommodation facilities, there are various usage forms such as jointly owning a villa in a resort area and adjusting the usage time among co-owners, and so-called private accommodation where an individual-owned real estate is provided as an accommodation facility. These have been proposed and realized. Affected by the increasing global tourism boom, the number of Japanese travelers and travelers from abroad has increased significantly even in our country. Along with this, the demand for accommodation real estate has also increased. In response to such an increase in demand, the setting of short-term use rights for real estate, for example, reservations for accommodation facilities, cannot be sufficiently handled by the previous telephone exchanges, and reservation systems via web pages and the like using IT technology are being utilized.
[0003] For example, Patent Document 1 discloses a technology for realizing the sale of accommodation facilities by travel agencies on a website installed on the accommodation facility side. Further, Patent Document 2 discloses a technology for aggregating reservation information made via a plurality of reservation sites on the accommodation facility side regarding the management of accommodation facility use reservations.

Summary of the Invention
Problems to be Solved by the Invention
[0005] Regulatory relaxations are also being advanced with the expansion of the demand for short-term use of real estate. For example, in the past, when providing real estate to a third party for short-term use purposes, it was necessary to obtain prior permission from the competent authority based on the Hotel Business Act. However, in the case of private lodging (although certain conditions are imposed), legislative measures have been taken so that it suffices to file a notification.
[0006] In view of such a situation, it is expected that the secondary circulation of the short-term use right of real estate will be widely carried out in the near future. In the case of secondary circulation, it is assumed that both the purchasers of the use right and the sellers will include those who do not have sufficient knowledge of real estate use. For such sellers, for example, it is not easy to appropriately disclose the use conditions of the real estate set by the owner, appropriately set the price, and avoid selling the use right to problematic purchasers. Even for purchasers of the use right, when purchasing the use right from a seller who is not an expert such as a travel agent, problems such as to what extent the seller can be trusted will arise.
[0007] Therefore, in order to promote smooth secondary circulation even when those without specialized knowledge become sellers or purchasers, a system for appropriate circulation management is necessary. However, neither Patent Document 1 nor Patent Document 2 discloses any such technology.
[0008] The present invention has been made in view of the above problems, and an object thereof is to provide a technology for providing necessary and accurate information for transactions to a trader who intends to conduct a transaction regarding a property use right, which is a use right of a real estate property.

Note that when generating the past transaction information, information provided by the owner / manager of the property and / or past transaction parties may be utilized, or publicly available information may be utilized, or information regarding past concluded transactions may be pre-recorded and the recorded information may be utilized.
[0022] The neighboring price information generation unit 15 is for generating neighboring price information, which is information on the usage right prices of other properties located in the vicinity of the property subject to distribution management. Specifically, the neighboring price information generation unit 15 has a function of generating neighboring price information, which is information including information on the usage right prices of other properties of the same type located within a certain distance range from the neighboring property, for example, the property subject to distribution management. Note that the neighboring price information is used as reference information when determining the usage right price of a property. Although it is preferable that the "other properties" are the same or similar to the target property in terms of physical structure, neighboring price information may also be generated including properties that differ to a certain extent as "other properties". When the physical structures of the properties are different, it may be possible to correct the usage right price in the case where the physical structures match (for example, if the other property has twice the area of the target property, the usage right price is corrected to half and then information generation is performed), or information generation may be performed in a manner that clearly shows the different parts in terms of physical structure. Also, as the content of the neighboring price information, it may be in a form that includes information on the usage right prices of individual other properties, or it may include information on the usage right price of the target property estimated based on the usage right prices of individual other properties so that it can be easily referred to. Note that when generating the neighboring price information, information provided by the owners / managers of neighboring other properties or past traders related to the usage rights of such other properties may be utilized, or public information may be utilized, or information on transactions related to other properties that have been concluded in the past may be recorded in advance and the recorded information may be utilized.

For example, it includes information such as the physical structure information of the facility, information about the usage mode of the facility, and information about the attention level of tourists. In generating the neighboring facility information, information provided by the owner / manager of the facility may be utilized, or public information such as maps may also be utilized.
[0024] The neighboring event information generation unit 17 is for generating neighboring event information, which is information about events held in the vicinity of the property subject to distribution management. Specifically, the neighboring event information generation unit 17 has a function of generating neighboring event information, which includes information about events held within a certain distance range from the property subject to distribution management, such as sports events, music concerts, theatrical events, special exhibitions with segmented periods in museums, summer festivals, fireworks displays, etc. Note that the neighboring event information generation unit 17 places no special restrictions on the implementation time of the events for the neighboring event information generated. From the perspective of being used as reference information for future property use right transactions, it is desirable to include at least information about events to be held in the future.
[0025] The sales condition information generation unit 18 is for generating sales condition information which is information on the restrictive conditions for the sale of property use rights. Specifically, the sales condition information generation unit 18 has the function of generating sales condition information including specific sales restrictive conditions for the sale of property use rights, such as not being allowed to sell at a price lower than the price specified by the property administrator, not being allowed to resell until a certain period has elapsed since the purchase of the use right, not being allowed to sell to a certain attribute (such as a legal person like a company), and only being allowed to sell to persons with a specified attribute among the traders. In addition, when generating the sales condition information, it is preferable to utilize the information published and provided by the property owner / manager and the information regarding legal regulations.
[0026] The property disclosure condition setting unit 2 is for setting property disclosure conditions which are the disclosure conditions of individual information included in the generated property information, such as property structure information, past transaction information, neighboring price information, neighboring facility information, neighboring event information, and sales condition information.

[0038] The object token generated by the object token generation unit 5 represents the right to use the corresponding object, and the person who holds the right to use the corresponding object holds the object token. Specifically, the person who holds the right to use the object at the time when the object token is generated by the object token generation unit 5 holds the object token, and when the right to use the object is transferred by means of transaction or the like, the holder of the object token also transfers accordingly. Further, an object transaction generated based on information including information about the owner / manager of the object corresponding to the object token and object information which is information about the right to use the object is output and stored in a block constituting a distributed ledger on a distributed network forming a blockchain.
[0039] "Blockchain" is a technology for data synchronization while utilizing cryptographic techniques among a plurality of computers constituting a distributed network. Specifically, each block is composed of an aggregate of information about tokens such as agreed transaction records and information (information of the previous block) for connecting to other blocks, and the blockchain is constituted by connecting a plurality of such blocks. Since correct data is selected by a majority vote with other computers even if data tampering occurs in a part of the plurality of computers, it has the feature that it is extremely difficult to destroy or tamper with data.
[0040] As the correspondence between the object token and the object, it is in the form of associating the identifier of the object token with the identification information of the object. Although the correspondence between the object and the object token is basically one-to-one, for example, a group of objects having a certain commonality (for example, a plurality of different rooms existing in the same building, etc.) may be associated with a single object token, and object information regarding each of the group of objects may be recorded in a block constituting the distributed ledger.
[0041] Regarding the generation of property tokens, the property token generation unit 5 may generate them by itself, or it may be in a mode where an external system directly or indirectly connected to the property token generation unit 5 generates them by issuing a predetermined command. Also, regarding the specific form of the property tokens, they are not limited to those conforming to ERC721, which is the standard of Ethereum (registered trademark). Any form is acceptable as long as it has the property of non-fungibility and the transaction history is stored in the blocks constituting the distributed ledger that has a correspondence relationship with the property tokens on the distributed network forming the blockchain.
[0042] The trader token generation unit 6 is for generating trader tokens, which are non-fungible tokens having a one-to-one correspondence with individual traders. Similar to property tokens, trader tokens are composed of non-fungible tokens with unique data, making them non-substitutable with other tokens. For example, they are issued based on ERC721, which is a project of Ethereum (registered trademark). Information including trader information related to the trader in correspondence with the trader token is stored in the blocks constituting the distributed ledger in correspondence with the trader token.
[0043] The property transaction generation unit 7 is for generating property transactions to be stored in the blocks in the distributed ledger in correspondence with the property tokens (i.e., recorded in the distributed ledger). Specifically, as the content of the property transactions, the property transaction generation unit 7 has a function of generating information including, in addition to information regarding the setting / change of the ownership name of the property tokens, property information, which is information regarding the corresponding property, and information regarding the property disclosure conditions, which are the disclosure conditions of the individual information constituting the property information.
[0044] The trader transaction generation unit 8 is for generating trader transactions to be stored in (i.e., recorded in) the distributed ledger in a corresponding relationship with trader tokens. Specifically, the trader transaction generation unit 8 has a function of generating information including, as the content of the trader transaction, information regarding the setting / change of the holding name of the trader token, trader information which is information regarding the corresponding trader, and information regarding the trader disclosure condition which is the disclosure condition of each piece of information constituting the trader information. Note that the trader transaction generation unit 8 may generate the trader transaction after encrypting these pieces of information to conceal them to a certain extent, or may form the output destination distributed ledger on a private blockchain.
[0045] The electronic signature generation unit 9 has a function of generating an electronic signature which is data for proving that the creation / output of information included in each of the property transaction and the trader transaction conforms to the intention of the holder of each of the property token and the trader token. Specifically, the electronic signature generation unit 9 generates a hash value for the property transaction and the trader transaction generated by the property transaction generation unit 7 and the trader transaction generation unit 8 respectively, and has a function of generating an electronic signature by encrypting the hash value with the private key held by the holder of each of the property token and the trader token. Note that the "hash value" is a fixed-length value obtained by performing a certain calculation procedure on the original data. Since the calculation procedure is irreversible, it is impossible to restore the original data from the hash value. Also, the "private key" is a sequence of numbers used for encryption processing, and has a configuration that can be decrypted by the corresponding "public key". In the first embodiment, the property transaction generation unit 7, the trader transaction generation unit 8, and the electronic signature generation unit 9 are configured to perform by themselves up to the creation of each transaction and the electronic signature related to each transaction, but it is not necessary to be limited to this, and the property transaction generation unit 7, the trader transaction generation unit 8, and the electronic signature generation unit 9 may have only a function of instructing an external predetermined device to create each transaction and the electronic signature related to each transaction.
[0046] The output unit 10 outputs the property transaction generated by the property transaction generation unit 7 and the electronic signature related to the property transaction generated by the electronic signature generation unit 9 to a distributed network in a corresponding relationship with the property token, and outputs the trader transaction generated by the trader transaction generation unit 8 and the electronic signature related to the trader transaction generated by the electronic signature generation unit 9 to a distributed network in a corresponding relationship with the trader token. As a specific aspect of the output unit 10, in the first embodiment, it is configured to directly output the transaction and the electronic signature, but it may also be configured to only instruct other components (including those provided outside the information providing system according to the first embodiment) to output. In the first embodiment, the output unit 10 is directly or indirectly connected to the distributed network and is configured in a manner capable of outputting predetermined data to the distributed network. The distributed network generates a hash value of each output transaction and compares it with the data obtained by decrypting the corresponding electronic signature with the public key (= the hash value of the transaction). If the two values are different, it is determined that the transaction is not genuine and the registration is rejected. If the two values match, it is determined that the transaction is genuine, and the information constituted by the transaction is stored in the block constituting the distributed ledger. Regarding the correspondence between each transaction and each distributed ledger, for example, it may be configured by associating 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 not only when the output unit 10 outputs information but also when the information acquisition unit 11 performs information acquisition processing.
[0047] The information acquisition unit 11 is for acquiring property information regarding the property use right that a trader intends to transact and trader information regarding another trader who will be the counterparty in the transaction at the time of the transaction of the property use right from a distributed ledger in which each piece of information is recorded, and outputting it to the information providing unit 12. Specifically, the information acquisition unit 11 includes a disclosure condition information acquisition unit 28 that acquires information regarding the disclosure conditions of the trader who is the destination of the acquired information, an information access unit 29 that accesses the distributed ledger storing the information to be acquired, and an information acquisition unit 30 that acquires information that can be disclosed under the acquired disclosure conditions among the information stored in the distributed ledger.
[0048] The disclosure condition information acquisition unit 28 is for acquiring disclosure condition information, which is information regarding the disclosure conditions of information in the trader who intends to acquire information. In the information providing system according to the first embodiment, for example, a trader who intends to purchase a specific property use right attempts to acquire, via the information acquisition unit 11, property information regarding the property use right and trader information (more precisely, seller information among the transaction information) regarding the trader who holds the property use right. Also, a trader who intends to sell the property use right attempts to acquire property information regarding the property use right and trader information (more precisely, purchaser information among the transaction information) regarding the person who has made a purchase offer or the trader who intends to inquire about a sale. In these cases, the disclosure condition information acquisition unit 28 has a function of enabling acquisition of information within the range where the disclosure conditions are satisfied when accessing the distributed ledger and acquiring information, by acquiring the disclosure condition information of the trader who intends to acquire information. Here, the "disclosure conditions" correspond to conditions A, B, C,... which are the disclosure conditions set by the property disclosure condition setting unit 2 and the trader disclosure condition setting unit 4. For example, the disclosure condition information acquisition unit 28 acquires the disclosure condition information based on, in addition to whether the trader is a paid member of the information providing system according to the first embodiment, whether the number of transactions of the property use right using the system is equal to or more than a predetermined number, whether the person has engaged in problem behaviors such as information leakage in the past, etc., and also based on attribute information such as the age, gender, nationality, educational background, work history, etc. of the trader.
[0049] The information access unit 29 is for accessing a distributed ledger that stores information that a trader wishes to obtain. Specifically, when the information to be obtained is property information regarding a specific property usage right, the information access unit 29 accesses a distributed ledger that has a correspondence relationship with the property avatar associated with the property. When the information to be obtained is trader information regarding a specific trader, the information access unit 29 has a function of accessing a distributed ledger that has a correspondence relationship with the trader avatar associated with the trader.
[0050] The information acquisition unit 30 is for acquiring the information recorded in the distributed ledger accessed by the information access unit 29. Specifically, the information acquisition unit 30 has a function of selecting, from the information recorded in the accessed distributed ledger, information that can be disclosed based on the disclosure condition information of the trader who wishes to obtain the information, and acquiring the selected information. For information that can be partially disclosed according to the disclosure condition (for example, only an approximate value of the past selling price of the property usage right can be disclosed, etc.), the information acquisition unit 30 shall perform necessary information processing (calculation of the approximate value, etc.) and then acquire the information.
[0051] The information providing unit 12 is for providing the property information acquired by the information acquiring unit 30 and the trader information about other traders to the traders who wish to acquire information. Specifically, the information providing unit 12 has a function of providing the information acquired by the information acquiring unit 30 to the traders who wish to acquire information as satisfying the disclosure conditions regarding the relevant traders. As a result, a trader, for example, as a purchaser (or a person who intends to become a purchaser) considering the purchase of a specific property use right, can examine whether to purchase by receiving the provision of the property information regarding the property use right, and can also examine the negotiation content by receiving the provision of the trader information (specifically, the seller information included in the trader information) regarding another trader who is the holder and seller (or a person who intends to become a seller) of the property use right. Alternatively, a trader, as a seller (or a person who intends to become a seller) considering the sale of the property use right held by himself / herself, can grasp the restrictive conditions regarding the sale of the property use right (for example, information regarding the minimum sale price, etc.) by receiving the provision of the property information regarding the property use right, and can judge whether the relevant trader is a suitable person as a purchaser by receiving the provision of the trader information (specifically, the purchaser information included in the trader information) regarding the purchaser (or a person who intends to become a purchaser), and can examine the negotiation content with the relevant trader when the relevant trader is a suitable person.
[0052] Next, the advantages of the information provision system according to Embodiment 1 will be described. The information provision system according to Embodiment 1 provides property information, which is information about the property use right that is the object of the transaction, to a person who is about to conduct a transaction of the property use right, and also has a function of providing trader information, which is information about another trader who is the counterparty of the transaction. By providing the property information, the trader who is about to conduct the transaction can grasp the details of the property use right that is the object of the transaction. When participating as a seller, for example, it becomes easier to explain the property to the purchaser, and it is possible to appropriately set the price, etc. based on the sales condition information, which is a restrictive condition, and then conduct the transaction. If the trader is a person who is about to participate in the transaction as a purchaser, it is possible to grasp the specific structure of the property related to the property use right from the property information and estimate the appropriate price of the property use right by grasping the past transaction details from the past transaction information.
[0053] Also, by providing trader information about another trader who is the counterparty of the transaction, the trader who is about to conduct the transaction, for example, when the trader participates in the transaction as a seller, can grasp from the purchase activity information the price range of the property use right that the counterparty trader has purchased in the past and use it as a reference for deriving the sales price. Based on the purchase evaluation information, the trader can also grasp whether the counterparty trader has a fact of delaying the payment of the purchase price, etc., and determine whether the trader can be tolerated as a counterparty. If it can be tolerated, it is possible to take measures such as deriving a sales price with a risk premium added. When the trader participates in the transaction as a purchaser, for example, based on the sales evaluation information, the trader can grasp whether the counterparty trader has caused any trouble in past transactions and determine the eligibility as a counterparty. Based on the property for sale information, the trader can also grasp the future value fluctuation of the property use right to be purchased from the same person, for example, the possibility of price increase, etc., and it is possible to make a judgment such as whether to purchase the property use right based on such information.
[0054] Furthermore, in the information providing system according to the first embodiment, among the individual pieces of information constituting the recorded property information and trader information, only the information that is permitted to be disclosed according to the disclosure conditions derived for each trader who provides the information is disclosed. By adopting such a configuration, it becomes possible to create a difference in the range of information that can be obtained between paid users and free users of the system, and to take measures such as significantly restricting the disclosed information for those who have engaged in problematic behavior in the past.
[0055] (Second Embodiment) Next, the information providing system according to the second embodiment will be described. In the second embodiment, with respect to the components having the same name and the same reference numerals as those in the first embodiment, unless otherwise specified, they shall exhibit the same functions as the components in the first embodiment.
[0056] FIG. 2 is a schematic diagram showing the configuration of the information providing system according to the second embodiment. As shown in FIG. 2, the information providing system according to the second embodiment, in addition to the configuration of the first embodiment, essentially includes purchase activity information in the purchaser information constituting the trader information, and has a usage right extraction unit 32 that extracts other property usage rights having commonality with the information regarding the property usage rights related to past purchases included in the purchase activity information in the trader information regarding the trader who is the information providing destination by the information providing unit 31. The information acquisition unit 33 acquires the property information regarding the property usage rights extracted by the usage right extraction unit 32 and the trader information regarding the trader who holds the property usage rights (i.e., the trader who can be the seller of the property usage rights), and the information providing unit 31 provides the property information and the trader information.
[0057] The usage right extraction unit 32 has a function of acquiring trader information regarding a trader who is an information provider, acquiring information regarding the usage rights of properties purchased in the past described in the purchase activity information included in the acquired trader information, and acquiring property information regarding the usage rights of the properties. Further, the usage right extraction unit 32 extracts another usage right of a property having property information that is common to the information included in the acquired property information, and outputs information regarding the extracted usage right of the property and information regarding the trader who holds the usage right of the property (that is, a trader who can be a seller of the usage right of the property) to the information acquisition unit 33.
[0058] The "commonality" in "property information having commonality with the information included in the property information" is a concept that includes, for example, not only information where the property information completely matches each other, but also cases where the individual information constituting the property information matches or is similar to each other. Also, since there are a large number of information constituting the property information, it is not necessary for all the information to match or be similar. Cases where a certain percentage or more of the information matches or is similar, or cases where only specific partial information matches or is similar may also be included in the case of "having commonality". For example, even in cases where the specific structure of the properties is similar, or events held in the vicinity of the properties are common (such as a fireworks display being held in the vicinity of both properties), or neighboring facilities are common (such as an art museum being located in the vicinity of both properties), they are also targets to be extracted as "property information having commonality".
[0059] Next, the advantages of the information providing system according to the second embodiment will be described. In the information providing system according to the second embodiment, the system extracts the property use rights that have commonality with the property use rights purchased by the trader who is the target of information provision, and has a configuration for providing property information regarding the property use rights having commonality and transaction information regarding the trader who is the holder of the property use rights. By adopting such a configuration, the information providing system according to the second embodiment can provide information regarding another property use right that has commonality with the property use right purchased by the trader in the past, that is, a new property use right that conforms to the trader's preference, and can present suitable purchase candidates to the trader, thereby having the advantage of promoting the transaction of property use rights.
[0060] As described above, the present invention has been described over Embodiments 1 and 2. Of course, the technical scope of the present invention should not be construed as being limited to the specific configurations described in the embodiments, and any various modifications and application examples to the above embodiments also belong to the technical scope of the present invention as long as they can realize the functions of the present invention. For example, although the use right extraction unit 32 is configured to provide information regarding a new property use right that conforms to the preference of the trader based on the property information regarding the property use right purchased by the trader in the past, not only the property use rights purchased in the past but also other property use rights may be extracted based on a wide range of general behavior histories (for example, based on the behavior history of having participated in music concerts many times in the past, extracting the property use rights regarding the property information in which it is described that a music concert will be held in the neighborhood in the neighborhood event information, etc.). Further, when extracting property use rights based on such behavior histories, the behavior history may be grasped based on the alternative tokens issued in other services used by the trader and the information recorded in the corresponding distributed ledger.
