<Details of the embodiment>
Hereinafter, the work ownership transaction management system (hereinafter referred to as “system”) according to the embodiment of the present invention will be described with reference to the drawings.

<Overview>
The system according to the embodiment of the present invention is a so-called art work (painting, print, sculpture, etc.) provided by a provider (examples of, but not limited to, artists, galleries, collectors, museums, foundations, companies, curators, etc.). One art work by selling to the user as the owner's right (although but not limited to examples such as planes, solids, objects, photographs, digital art, installations, public art, calligraphy, calligraphy, images, crafts, ceramics, etc.) It is a system for providing a service that can be jointly owned by multiple people.

In the following, the act of creating these works is defined by the term "creation", but it also includes terms used in the field, industry practice, and business practice such as creation, production, production, and manufacturing. Furthermore, the works (creations) obtained by the creation are, for example, novels, scripts, papers, lectures and other language works, music works, dance or silent drama works, paintings, prints, sculptures. Examples include other art works, architectural works, maps or drawings of academic nature, charts, models and other graphic works, movie works, photographic works, program works, etc. However, even if it is not strictly classified into these, it is included as long as it is a creative expression of thought or feeling.

<Structure>
As shown in FIG. 1, in this system 100, a work management server (hereinafter referred to as "management server") 1, a database 1a connected to the work management server 1, a user terminal 2, and a provider terminal 3 are connected to a network (Internet, etc.). It is connected and configured via a blockchain network).

In the present embodiment, at least the management server 1 is connected to the distributed ledger (blockchain) jointly managed in the blockchain network so that it can be accessed, referenced, and added (details will be described later).

<Hardware configuration>
As shown in FIGS. 2 and 3, the management server 1 and the user terminal 2 according to the present embodiment have the following hardware configurations. The following configuration is an example, and may have other configurations. Further, each functional block may be present in whole or in part in each terminal, or may be logically configured such as being available through a cloud service or the like.

<Management server 1>
As shown in FIG. 2, the management server 1 constitutes a part of the system by executing information processing via communication with the user terminal 2. The management server 1 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

The management server 1 includes at least a processor 10, a memory 11, a storage 12, a transmission / reception unit 13, an input / output unit 14, and the like, and these are electrically connected to each other through a bus 15.

The bus 15 is commonly connected to each of the above elements and transmits, for example, an address signal, a data signal, and various control signals.

<User terminal 2>
As shown in FIG. 3, the user terminal 2 constitutes a part of the system by executing information processing via communication with the management server 1. The user terminal 2 may be, for example, a user's smartphone terminal, tablet terminal or other mobile phone terminal, or may be a general-purpose computer such as a personal computer.

As shown, the user terminal 2 includes at least a processor 20, a memory 21, a storage 22, a transmission / reception unit 23, an input / output unit 24, and the like, which are electrically connected to each other through a bus 25. These functions may be shared with a control system such as an automobile.

Similar to the management server 1 described above, the processor 20 is an arithmetic unit that controls the operation of the entire user terminal 2, controls the transmission and reception of data between each element, and performs information processing and the like necessary for executing an application. For example, the processor 20 is a CPU (Central Processing Unit), and executes each information processing by executing a program or the like stored in the storage 22 and expanded in the memory 21.

The memory 21 includes a main storage configured by a volatile storage device such as a DRAM (Dynamic Random Access Memory) and an auxiliary storage configured by a non-volatile storage device such as a flash memory or an HDD (Hard Disk Drive). .. The memory 21 is used as a work area or the like of the processor 20, and also stores a BIOS (Basic Input / Output System) executed when the user terminal 2 is started, various setting information, and the like.

The storage 22 stores various programs such as an application program, an authentication program for a blockchain network, and an algorithm for controlling an automobile or the like. A database storing data used for each process may be built in the storage 22.

The transmission / reception unit 23 connects the user terminal 2 to the network 3. The transmission / reception unit 23 may be provided with a short-range communication interface of Bluetooth (registered trademark) and BLE (Bluetooth Low Energy).

The input / output unit 24 is an information input device such as a keyboard and a mouse used as needed, and an output device such as a display (touch panel).

The bus 25 is commonly connected to each of the above elements and transmits, for example, an address signal, a data signal, and various control signals.

<Processing flow>
Subsequently, with reference to FIG. 4, the information exchanged with the operation of each element shown in FIG. 1 will be described.

As shown in FIG. 4, each information processing is performed by a provider terminal 3 operated by a provider (artist, gallery, collector), a management server 1 (and a database 1a) operated by the system provider, and a user. It is performed with the user terminal 2.

From the provider terminal 3, information about the work that the provider himself wants to sell is provided to the management server 1. That is, the provider sells his / her own work or the work under his / her control to the system provider. The management server 1 receives the target work information and the price information from the provider, and sets the reference price of the owner right based on the price information. In the present embodiment, the transaction price of the work may be adjusted (corrected) from the current evaluation trend of the work or the author.

The "work" according to the present embodiment may include a work that has already been completed, a work that is currently being created, and a work that is about to be created.

The system provider performs authenticity and price assessment of the provided work, and issues digital ownership (hereinafter referred to as "ownership"). It is also possible to store the work itself in an appropriate place and environment. Furthermore, it is also possible to collect information related to the work and analyze the work itself. In the present embodiment, each user who has acquired the ownership right can receive a predetermined preferential treatment (details will be described later). The management server 1 also performs a process of selling the owner right from the user (= a process of repurchasing the owner right).

In this embodiment, the term "ownership right" is used, but the terming of the right is not limited to this. That is, any name may be used as long as it is a concept having the authority to own, manage, control, trade, buy or sell, dispose of, or modify the work itself.

In the illustrated example, each user of the user terminal 2 has a predetermined ratio of ownership (30%, 25%, 5%, 2%, etc.). Each user can own the asset value according to the ownership stake. Further, in the present embodiment, it is possible to hold an exhibition of works only by the owner or rent them out for ornamental purposes.

For example, each user can sell all (or a part of) his / her own ownership to another user (user terminal 2a) or purchase from another user.

In this way, according to this system, it is possible for a plurality of people to jointly own a work provided by a provider, and for example, even an expensive painting can be easily owned.

The example shown in FIG. 4 shows an example in which the provider sells all the ownership rights, but as shown in FIG. 5, the seller (= provider) may leave the ownership rights to himself / herself. .. In the illustrated example, the seller (provider) sells the remaining 90% of the ownership to the user while leaving 10% of the work with the evaluation value of 1 million yen on hand.

As shown in the figure, if the value increases after the sale due to buying and selling between users or the activity of the artist himself (for example, if the value is more than tripled in 3 years), the seller is 10% of himself / herself. It is also possible to sell the ownership of the product to another user. As a result, the value of the 10% ownership, which was equivalent to the initial evaluation value of 100,000 yen, will be tripled to 300,000 yen, and a profit of 200,000 yen can be obtained.

FIG. 6 is an example of a screen for the user to purchase. As shown, it is possible to see photos of the work, prices and details. In the purchase details screen shown in FIG. 7, the user sends a purchase request and a ratio to the system for the work for which the ownership is to be purchased.

On the purchase screen, the title of the work, the author, the date of completion of the work, the place of completion (country), the genre / attribute, the price of the work, the current frame unit price, the edition information, the information on the frame, the size, the state, and the past of similar works. Price transition, future price transition forecast, sales establishment amount, existence of authenticity certificate, authenticity certificate of the work, work commentary by an expert, video of the creation process, work introduction video, writer's career, work history information, purchase Number of desired users, current order status, remaining sales days, number of people who already have it, own ownership rate in the work, estimated holding rate of the work to be purchased in the own portfolio, past buy / sell order price, current Displays the number of slots owned by the artist, past unit price changes, unit price fluctuation rate over a specified period, difference from the average work price of the corresponding artist, other recommended works for purchase, news about the work and the artist, and other attribute information. You may do it. In addition, this information may be different between the case of purchasing a new ownership right for the work and the case of buying and selling the ownership right already held. The payment process is started when the user further inputs information regarding the purchase intention and the ratio.

In the present embodiment, each owner can appreciate the target work related to the ownership right together with the image or the video of the target work. For the predetermined work (= work for which the provider has given permission, etc.), for example, the image or video of the work related to the ownership that oneself owns may be shared with other users.

As shown in FIG. 9, the user has the ownership right for each predetermined attribute (work name, author, work completion date, completion place (country), genre / attribute, and other attributes. Information) may be used to visualize how much it is possessed (the example shown is for one type of work). A valuation gain or loss based on the current valuation is displayed at the same time.

Information on works and recommended works may be displayed on the same screen.

By sending the ownership sale request and the sale ratio to the system, the user can sell the ownership at a price determined based on the sale ratio and the current transaction price of the ownership. .. When the system receives the ownership sale request and the sale ratio from the user terminal, the system executes the sale settlement process.

As shown in FIG. 8, the transition of the transaction price of the two types of ownership may be displayed.

Various factors can be taken into consideration in the price according to the present embodiment. For example, the price may be corrected according to information such as external evaluation of the work or its author, past evaluation, prediction of future evaluation, and the like. Further, it can be corrected according to the transaction status performed by the system 1 itself. Further, the price may be determined by a combination of these.

Further, by comprehensively judging such an evaluation and predicting the future price, it may be possible to give advice to the user such as when to sell the owner's right or when to purchase.

The above-mentioned price is related to a work that has already been completed, but for example, an owner right for a work to be created may be issued and traded. In this case, for example, the provider side (artist, etc.) can obtain the funds first. You can concentrate on the creative activities of your work.

In this case, the price of ownership is determined by factors such as the evaluation of the creator of the work, the type, scale, or attributes of the work to be created. The price determined by this standard is determined at a predetermined timing.

The management server manages information on the ownership purchase request and the purchase ratio, and the ownership sale request and the sale ratio on the blockchain. An example of blockchain management will be described with reference to FIGS. 9 to 11.

In the following description, an example in which information on ownership is passed in the order of owner, management server, and user will be described.

As shown in FIG. 9, (A) stores the public key hash value of the management server as the transferee from the owner, and (B) stores the main body of the public key of the management server. .. Authentication is performed by collating the public key hash value of the management server included in the Pubkey Script of (A) with the public key body of the management server included in the Signature Script of (B).

Specifically, the hash value of the public key body of the management server included in the Signature Script of (B) is generated, and it is confirmed that the hash value matches the public key hash value of the management server included in the Pubkey Script of (A). As a result, the ownership has been transferred from the owner to the management server.

As shown in FIG. 12, the management server creates and provides its own private key in advance in order to digitally sign the ownership with respect to the deposit. Specifically, it is an electronic signature included in the Signature Script of (B).

The digital signature is generated as follows. That is, the transaction ID (TX_ID) of (A) and the public key hash value of the management server are taken out, and the right_ID and user public key hash of (B) are added (see (X) in the figure). This is encrypted (signed) with the private key of the management server included in (B). The electronic signature constitutes a part of the electronic signature of (B).

Next, the verification of the electronic signature when the ownership of the management server is passed to the user (that is, the user purchased the ownership) will be described. As shown in FIG. 13, the digital signature verification uses the public key of the management server. As mentioned above, the public key is the same as the one specified as the hash value included in the Pubkey Script in the transaction (A).

When the digital signature of (Y) is decrypted with the public key of the management server and restored, a certain hash value (“hash value B” in the figure) is obtained. On the other hand, the original information that created the hash value described with reference to FIG. 12 is collected again from the transaction data to create the hash value A. If the hash value A and the hash value B are matched and matched, it is proved that the management server has the private key corresponding to the public key specified as the destination in the transaction (A).

From the above, it is possible to confirm and verify the legitimacy that the owner has transferred the work (right_ID) to the management server and the legitimacy that the owner right stored in the management server is received by the user. Further, by including the public key hash information of the other party to whom the ownership right is to be transferred in the information related to the transaction, only the other party can surely receive the ownership right.

Normally, it is recommended to renew the public key pair in units of one transaction.

The embodiments described above are merely examples for facilitating the understanding of the present invention, and are not intended to limit the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes its equivalents.
