Description

The present invention relates to a technology for handling digital art, and in particular to a technology that is effective when applied to a digital art exhibition system that displays digital art borrowed from an owner.

The use of NFT (Non-Fungible Token), a technology that creates unique and non-fungible data units on blockchain, is rapidly expanding. By associating easily replicable digital data with NFTs (converting them into NFTs), it has become possible to turn the digital data into unique assets and make them the subject of transactions. Examples of digital data that can be traded include trading cards, in-game characters, items, and other types of content, as well as digital art created by artists. There is.

As a technology that applies NFT to digital art, for example, International Publication No. 2020/080537 (Patent Document 1) states that it is possible to record and manage accurate information regarding the origin and history of distributed art, etc. on a blockchain. In addition to copyright income and income from the sale of ownership rights related to the art, etc., there is a system that allows for the receipt of return income from secondary sales and distributions when derivative works are sold. Are listed.

In addition, Japanese Patent Laid-Open No. 2021-189475 (Patent Document 2) allows users to convert objects such as in-content currency obtained by using content such as games into crypto assets, and uses the crypto assets to By making it possible to trade the rights to use digital works such as in-game characters and items, it becomes possible to own and monopolize these digital works, and it also makes it possible for the general public who is not familiar with crypto assets etc. It describes a mechanism that allows even ordinary users to trade the rights to use digital works as long as they play the content.

International Publication No. 2020/080537 JP 2021-189475 Publication

For example, according to the technology described in Patent Document 1 mentioned above, the owner of digital art can turn it into NFT and make profits by trading it on a marketplace, but the revenue from buying and selling is the target. This has a strong implication that NFT art is treated as an investment target focusing on its asset value. In order to effectively utilize the value of NFT art as works of art, it is important to actually exhibit them so that people can see and experience them. On the other hand, managers and organizers of facilities and events where people gather, for example, do not require them to own NFT art, but they do so by displaying NFT art that is in harmony with the venue they manage. There is also a need to increase satisfaction.

According to the technology described in Patent Document 2 mentioned above, it is possible to trade the usage rights (ownership rights) of digital works, but it is not possible for the users themselves to obtain the usage rights (ownership rights). The purpose of the content is to use the content (for example, play a game) in order to obtain the crypto assets as compensation for acquisition, and the content is used for the purpose of This cannot meet the needs of realizing a system for displaying NFT art that is not owned.

Therefore, the purpose of the present invention is to enable NFT art to be used not only as an investment object through marketplace transactions, but also to be effectively exhibited and utilized as a work of art, while also allowing the owner to generate profits. Our goal is to provide a digital art exhibition system that

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

A brief overview of typical inventions disclosed in this application is as follows.

A digital art exhibition system that is a typical embodiment of the present invention is a digital art exhibition system in which an exhibitor displays digital art borrowed from an owner, and in which the exhibitor displays digital art borrowed from an owner. A marketplace processing unit that issues an NFT certificate and processes transactions related to the digital art, and registers lending conditions related to the digital art set by the owner in the NFT certificate, and processes transactions related to the digital art. a borrowing processing unit that receives a request to borrow the digital art, registers the borrowing conditions in the NFT certificate, and records the exhibition conditions related to the digital art set by the exhibitor; When it is determined that the user is located in a predetermined exhibition area, the borrowing processing unit extracts digital art that can be displayed in the exhibition area from among the borrowed digital art, and the extracted digital art is displayed by the user.

<Summary>
The digital art exhibition system, which is an embodiment of the present invention, is compatible with the exhibition of art works in, for example, airport lounges where only users who meet certain conditions can enter, hotel lobbies, restaurants, etc. This is a system that uses AR (Augmented Reality) to display and display NFT art in places where users may be able to appreciate it. The exhibition location is not particularly limited as long as it is a place where artwork can be exhibited, and may be a museum where the purpose is to display and appreciate art, a restaurant or retail store, indoors or outdoors. It may be an event venue, etc. It may be a place where only users who meet predetermined conditions can enter, or it may be a place where anyone can enter freely. Note that in this embodiment described below, an airport lounge will be described as an exhibition location.

Furthermore, in this embodiment, NFT art is displayed and exhibited using AR, but it is not limited to AR as long as it is a method that can display digital art, such as VR (Virtual Reality). , MR (Mixed Reality), SR (Substitutional Reality), and XR (Cross Reality/Extended Reality), in other words, by merging the real world and the virtual world. The structure may be such that the display is displayed using a technology that allows the user to perceive things that are not real (hereinafter sometimes referred to as "various types of reality display").

In this embodiment, physical space and virtual space are fused by displaying NFT art that matches the atmosphere of an exhibition location such as an airport lounge using AR. It is assumed that the exhibitor at the airport lounge etc. has received the loan (borrowed). In other words, exhibitors in airport lounges, etc., do not display NFT art that they own (this does not preclude the display of NFT art that they own), but rather they receive information from the owner on behalf of the owner of the NFT art. This will be exhibited after being borrowed (with permission to use it for exhibition).

Users of the airport lounge can view the NFT art exhibited through AR display, and can also purchase works of art that they like. As a result, the owner of NFT art can earn profits by lending the NFT art, and can also earn profits by selling the NFT art if it is purchased.

<System configuration>
FIG. 1 is a diagram showing an overview of a configuration example of a digital art exhibition system that is an embodiment of the present invention. The digital art exhibition system 1 includes, for example, a digital art exhibition server 10, a blockchain 5 configured on the Internet via a blockchain service (not shown), and a user such as a smartphone owned by a user 4 of an airport lounge or the like. It is configured to include a terminal 41.

The digital art exhibition server 10 is configured by, for example, a server device, a virtual server built on a cloud computing service, a PC, etc., and is configured by a CPU (Central Processing Unit) (not shown) to drive an HDD (Hard Disk Drive) or SSD (Solid Disk Drive). NFT art can be borrowed by running middleware such as an OS (Operating System), DBMS (DataBase Management System), or a web server program developed on memory from a recording device such as a storage device such as a state drive (State Drive), or software that runs on it. and various functions related to exhibitions, etc.

This digital art exhibition server 10 includes various parts such as a marketplace processing section 11, a borrowing processing section 12, and an exhibition processing section 13, which are implemented as software, for example. It also has data stores such as a digital art database (DB) 14 and an exhibition condition DB 15 implemented as databases, files, and the like. Note that in the example in Figure 1, each of these components is represented as if it were implemented on one server system, but this is a logical representation, and in reality, some or all of the components are implemented on one server system. They may be implemented as individual servers, systems, services, etc., and configured to cooperate via a network (not shown).

The marketplace processing unit 11 has a marketplace function that processes transactions such as buying and selling of NFTs such as NFT art. OpenSea (registered trademark, https://opensea.ip/) and other existing NFT marketplace platforms may be used, or a unique NFT marketplace platform may be newly implemented. The digital art owner 2 can list and trade the digital art 21 that he or she owns on the marketplace via the marketplace processing unit 11.

When the digital art 21 is put up for sale on the marketplace, the marketplace processing unit 11 issues an NFT certificate on the blockchain 5 to prove that it is genuine. For example, this can be done by registering predetermined work information related to the digital art 21 using the smart contract function of the blockchain 5. Further, the data and work information of the exhibited digital art 21 may be registered in the digital art DB 14. Payment for transactions may be made using virtual currency (crypto assets) on the blockchain 5, or may be made using other payment methods such as credit cards, miles, and points.

The borrowing processing unit 12 selects digital art 21 that has been exhibited in the marketplace and registered in the digital art DB 14 and that is registered in the NFT certificate etc. as being able to be lent by the digital art owner 2 at the airport. It has a function of borrowing (obtaining permission for exhibition) items from the digital art owner 2 that are candidates for display in an exhibition area 31 such as a lounge. The borrowed digital art 21 is registered in the exhibition condition DB 15 along with information on conditions such as the borrowing period and the exhibition area 31 to be displayed, and also in the NFT certificate. Even if rent is incurred when borrowing, it may be paid by sending virtual currency (cryptocurrency) on blockchain 5 to digital art owner 2, for example, in the same way as payment of transactions on the marketplace. However, other payment methods such as credit cards may be used.

The exhibitor 3 will select and borrow the digital art 21 that matches the atmosphere of the exhibition area 31 such as an airport lounge, but he or she may select the digital art 21 manually or specify the desired conditions in advance so that the digital art 21 matches the atmosphere of the exhibition area 31 such as an airport lounge. The digital art 21 may be automatically selected by the borrowing processing unit 12. For example, suitable digital art 21 may be extracted using AI based on image data obtained by photographing the exhibition area 31. Furthermore, the rental conditions (period, rent, etc.) that have been preset by the digital art owner 2 and registered in the exhibition condition DB 15 and the NFT certificate of the blockchain 5, and the rental conditions (period, rent, etc.) desired by the exhibitor 3. etc.) may be matched.

Regarding lending/borrowing of the digital art 21, for example, the exhibitor 3 who is the tenant receives permission for exhibition based on the copyright related to the digital art 21 from the digital art owner 2 who is the lender. However, similar to the lending and borrowing of physical works of art, only one exhibitor 3 can borrow any digital art 21 at a given time, and only that exhibitor 3 has exclusive rights. It may be something that can be used for exhibition at any time, or it may be something that can be borrowed by a plurality of exhibitors 3 or third parties at the same time. Furthermore, even if the exhibitor 3 exclusively borrows the exhibit, it may be possible to display the exhibit simultaneously in a plurality of exhibition areas 31 managed by the exhibitor 3.

The exhibition processing unit 13 extracts the digital art 21 borrowed by the borrowing processing unit 12 that matches the location of the exhibition area 31, the exhibition period, and other exhibition conditions, and uses the exhibition area 31 such as an airport lounge. When the user 4 takes a picture of the exhibition area 31 using a camera function via an application (not shown) installed in the user terminal 41, the digital art 21 is displayed in an appropriate place according to the exhibition conditions by AR display. Has a function.

As a configuration for performing AR display on the user terminal 41, for example, the exhibition processing unit 13 transmits data necessary for AR display to the user terminal 41, and the received user terminal 41 performs AR processing and displays the data. It can be configured as follows. Alternatively, a configuration may be adopted in which the exhibition processing unit 13 side executes the processing necessary for AR display, and the user terminal 41 simply displays the content transmitted from the exhibition processing unit 13 as is, or a combination of these configurations may be used. You can also use it as

The exhibition area 31 where the digital art 21 is displayed is not fixed to one specific place. For example, in the case of an airport lounge, the exhibition area 31 where the digital art 21 is displayed may be rotated to multiple airport lounges across the country for a certain period of time. If possible, depending on the lending/borrowing conditions of Art 21, it may be displayed simultaneously in multiple airport lounges. Furthermore, even in the same airport lounge, different digital art 21 may be displayed depending on the attributes of each user 4, and even in the same airport lounge, different digital art 21 may be displayed for users 4 who visit multiple times. may display a different digital art 21 each time.

Note that the method for acquiring the attribute information of each user 4 includes, for example, facilities and equipment of transportation companies such as airlines, railway companies, bus companies, and taxi companies (for example, as described in this embodiment). Applications for members (exclusive to facilities such as airport lounges, etc.) provided by facilities or equipment with fixed geographical locations such as airport lounges, railway lounges, bus stops, taxi shelters, etc., or available at these facilities and equipment, etc. Each user 4 can inquire about attribute information by installing and using the application (including the application used in the above) on the user terminal 41. The application may include and provide various functions of the user terminal 41 described in this embodiment. Furthermore, if User 4 has obtained a marketplace account (described later) through linked authentication with the member information mentioned above, by starting the application and logging in, he or she can log in to the application and the marketplace. It is also possible to have a configuration in which both are performed at the same time.

Regarding whether or not the target user 4 is located within the exhibition area 31 such as an airport lounge, for example, the latitude and longitude information acquired by the GPS (Global Positioning System) function of the user terminal 41 is determined based on the predetermined information. This can be determined based on whether the location is within the latitude and longitude range. Not limited to GPS, for example, by the user terminal 41 detecting predetermined beacon signals, WiFi signals, etc. transmitted within the exhibition area 31, it is possible to identify which exhibition area 31 based on the identification information of these signals, etc. Known and commonly used techniques, such as determining whether the computer is located within the computer, can be used as appropriate. With these techniques, it is possible to realize location-type AR that displays digital art 21 according to the location of user 4.

Note that the exhibition area 31 for displaying the digital art 21 is not limited to facilities with fixed geographical locations such as airport lounges, railway lounges, bus stops, and taxi shelters, which are described in this embodiment, but for example, It uses beacon signals, WiFi, etc. to determine whether non-fixed equipment such as airplanes or vehicles is being used (riding), and digital art 21 is displayed in AR only when these equipment are being used. You may also do so.

When displaying digital art 21 in AR in an exhibition area 31 such as an airport lounge, for example, a commonly used marker-type AR display can be used to display the digital art 21 in a form that matches the interior, furniture, fixtures, etc. of the exhibition area 31. It is displayed according to the markers set in advance in the display condition DB 15. The example in FIG. 1 shows an example in which the digital art 21 is displayed in AR on the screen of the user terminal 41 above a table installed in the exhibition area 31.

The user 4 can also purchase the digital art 21 displayed in AR on the user terminal 41 if desired. For example, when the user 4 presses a "purchase" button (not shown) displayed on the screen together with the digital art 21 displayed in AR, the purchase process in the marketplace processing unit 11 (digital art owner 2). This allows the user 4 to purchase the digital art 21 and become the new owner. At this time, if the user 4 does not have an account on the marketplace, he or she registers a new account and purchases the item.

If the user 4 purchases the digital art 21, the user 4 will become the new digital art owner 2 from now on with respect to the digital art 21, and the relationship between the original digital art owner 2 and the exhibitor 3 will be changed. The rental/borrowing contract may be considered to have ended. In this case, unless the new digital art owner 2 re-lists it on the marketplace and the exhibitor 3 processes it for borrowing, third parties will not be able to view it on the marketplace, and the AR display in the exhibition area 31 will not be possible. Not done.

Alternatively, in order to ensure that the digital art 21 is displayed in the exhibition area 31 for a predetermined period, the purchase process by the user 4 is treated as a purchase reservation, and the marketplace processing unit 11 processes the purchase after the predetermined exhibition period ends. Transaction processing such as payment and transfer of ownership may be performed, or after transaction processing is performed, only AR display in the exhibition area 31 is possible continuously during the exhibition period (if the status of the lender is The digital art may be transferred to a new owner 2, and the state in which it is borrowed by the exhibitor 3 may be maintained.

In addition, if the user 4 thinks that the digital art 21 displayed in AR on the user terminal 41 is good, he or she may, for example, make a so-called "throwing coin" or press the "like" button to rate the digital art 21. It may also be possible to allow users to vote. Miles, points, etc. may be used for the "tips". Further, for example, the user 4 may input a comment at a specific viewpoint position regarding the digital art 21 displayed in AR, and may also be able to refer to comments including those from other users 4.

Digital art 21 that is judged to have a certain level of evaluation or popularity based on the number of "tips", "likes", the content of comments, etc. will be prioritized for display in the exhibition area 31. Alternatively, works that are no longer popular or old works may be excluded from the exhibition as the exhibition has ended. When determining popularity, we not only use indicators such as the number of "likes" but also obtain the length of time the AR is displayed from log information, and the longer the AR display time, the higher the rating and the higher the popularity. It may be treated as a certain work.

<Processing flow>
FIG. 2 is a diagram showing an overview of an example of the flow of processing related to a marketplace in an embodiment of the present invention. Here, an example of the flow of processing is shown when the digital art owner 2 newly puts the digital art 21 that he or she owns up for sale on the marketplace.

The digital art owner 2 first accesses the digital art exhibition server 10 using a web browser or marketplace application installed on a terminal such as a smartphone or PC (not shown), and logs into the marketplace (S01 ). The marketplace processing unit 11 performs login processing (S02). If the digital art owner 2 does not have a marketplace account, he or she creates a new account and logs in.

After that, the digital art owner 2 inputs information related to the digital art 21 to be exhibited (S03), and then sends the data of the digital art 21 to the marketplace (or the digital art exhibition server 10) via the marketplace processing unit 11. (S04). Information related to the digital art 21 to be put up for sale includes, for example, the title of the work, the creator, the date of creation, and the selling price.

The marketplace processing unit 11 registers the data of the uploaded digital art 21 in the digital art DB 14 (or blockchain 5) (S05), and issues an NFT certificate for the digital art 21 on the blockchain 5 (S05). mint) (S06), and performs listing processing such as publishing the digital art 21 so that it can be traded on the marketplace (S07). Furthermore, due to the smart contract function of Blockchain 5, the NFT certificate contains, for example, the information of the target digital art 21, as well as the history of the owner (ownership, date of transfer of ownership, etc.) and rental history. Information (borrower, loan period, etc.) is recorded. Address (wallet) information on Blockchain 5 of the creator, owner, and borrower is also associated.

On the other hand, the digital art owner 2 inputs information regarding whether or not to permit the exhibited digital art 21 to be rented out for exhibition, and if so, the conditions for lending (period, rent, display method, etc.). (S08), the borrowing processing unit 12 registers this in the exhibition condition DB 15 and also registers it in the NFT certificate using the smart contract function of the blockchain 5 (S09). This allows the digital art owner 2 to put the digital art 21 up for sale on the marketplace and also lend it to the exhibitor 3 to display it in the exhibition area 31.

FIG. 3 is a diagram illustrating an overview of another example of the flow of processing related to the marketplace in an embodiment of the present invention. Here, an example of the flow of processing when a user newly purchases digital art 21 on the marketplace and becomes the digital art owner 2 is shown. In addition to the case where a general user newly purchases digital art 21 on the marketplace, this also includes the case where user 4 in the exhibition area 31 purchases digital art 21 displayed in AR, as will be described later.

Similar to the example in FIG. 2 above, first, the user (later the new digital art owner 2) accesses the digital art exhibition server 10 using a terminal such as a smartphone and logs in to the marketplace ( S11), the marketplace processing unit 11 performs a login process (S12).

Thereafter, the user uses a marketplace application or the like to view the digital art exhibited on the marketplace (S13) and makes a purchase request for the desired item (S14). The marketplace processing unit 11 processes the payment of the purchase price using virtual currency (crypto assets), credit card, miles, points, etc. (S15), and when the payment is made, the smart contract function of the blockchain 5 allows the The NFT certificate related to the digital art 21 is updated by registering that the user who purchased it is the new owner (new digital art owner 2) (S16).

On the other hand, similar to the example shown in FIG. (Rent, exhibition method, etc.) (S17), the rental processing unit 12 registers (or updates) this in the exhibition condition DB 15, and uses the smart contract function of the blockchain 5 to enter information related to the target digital art 21. It is also registered (or updated) in the NFT certificate (S18). Thereby, the new digital art owner 2 can lend the digital art 21 to the exhibitor 3 and have it displayed in the exhibition area 31.

Furthermore, as mentioned above, if the digital art 21 to be purchased is on display (on loan) in the exhibition area 31, it may be treated as a purchase reservation in which buying and selling is reserved until the end of the exhibition period. , the status of the previous digital art owner 2 as a lender may be inherited by the new digital art owner 2, and the exhibition may be continued.

FIG. 4 is a diagram showing an overview of an example of the flow of a process for borrowing digital art 21 according to an embodiment of the present invention. Here, an example of the flow of processing is shown in which an exhibitor 3 borrows an item that is a candidate for display from among the digital art 21 exhibited in the marketplace.

An exhibitor 3 who wishes to exhibit digital art 21 in an exhibition area 31 such as an airport lounge uses a web browser, exhibition application, etc. installed on a terminal such as a smartphone or PC (not shown) to display digital art 21 on the digital art exhibition server 10. and displays a list of digital art 21 that can be exhibited (S21). At this time, the rental processing unit 12 of the digital art exhibition server 10, for example, rents out the digital art 21 registered in the digital art DB 14 (or located on the blockchain 5) set by the digital art owner 2. Conditions and exhibition conditions (for example, rental period, rent, rental area and location, restrictions on exhibition method, etc. If it is an exclusive rental, this also includes the fact that it is not lent to others). A list of items matching the specified desired conditions is extracted and obtained (S22).

After that, the exhibitor 3 selects the one to actually borrow and display from the list of digital art 21 that can be displayed (S23), and inputs the borrowing conditions (for example, the borrowing period, information on the exhibition area 31 to be displayed, etc.) (S24), and then applies for borrowing (S25). As mentioned above, when selecting the digital art 21, the exhibitor 3 may manually select one that matches the atmosphere of the exhibition area 31 such as an airport lounge, or specify desired conditions in advance. The rental processing unit 12 may automatically select one that meets the conditions. A suitable one may be selected by AI based on image data obtained by photographing the exhibition area 31.

The borrowing processing unit 12 of the digital art exhibition server 10 that receives the borrowing application uses the smart contract function of the blockchain 5 to transfer the information about the exhibitor 3 who is the tenant, the lending/borrowing period, and other information included in the application information to the smart contract function of the blockchain 5. The NFT certificate is updated by registering it with the NFT certificate (S26). This means that the exhibitor 3 has borrowed the digital art 21 in question.

The exhibitor 3 sets exhibition conditions for the borrowed digital art 21 so that it is displayed in AR in an appropriate place in the exhibition area 31 in an appropriate form (S27), and then sends the borrowing processing unit 12 of the digital art exhibition server 10 ( Alternatively, the exhibition processing unit 13) registers information on the set exhibition conditions in the exhibition condition DB 15 (S28). Information on exhibition conditions includes, for example, latitude/longitude range information that specifies the exhibition area 31, beacon signal identification information, marker information that specifies the exhibition location within the exhibition area 31, and the display size of the digital art 21. , orientation, and other display settings information.

FIG. 5 is a diagram illustrating an overview of an example of display processing of digital art 21 using AR display according to an embodiment of the present invention. Here, an example of a process flow is shown in which matching digital art 21 is displayed in AR when user 4 is located in exhibition area 31 such as an airport lounge.

The user terminal 41 owned by the user 4 uses a dedicated application for realizing AR display (for example, an airline application that can be used by airport lounge users) to activate the GPS function at regular intervals. (S31), and determines whether there is any digital art 21 that can be exhibited at the location, that is, whether the user 4 is in any of the exhibition areas 31 and if the user 4 is in any of the exhibition areas 31. 31, the digital art exhibition server 10 is inquired as to whether there is any digital art 21 that can be exhibited (S32).

The exhibition processing unit 13 of the digital art exhibition server 10 refers to the exhibition condition DB 15 (or the blockchain 5) and obtains a list of digital art 21 that is currently available for loan by the exhibitor 3 (S33). This list may be obtained each time an inquiry is received from the user terminal 41 as shown in FIG. 5, or it may be obtained separately and reused once a day. You can do it like this.

Then, the exhibition processing unit 13 determines whether the user 4 is in any of the exhibition areas 31 based on the position information of each exhibition area 31 registered in the exhibition condition DB 15 and the position information sent from the user terminal 41. If the digital art 21 is located in any of the exhibition areas 31, it is determined whether the digital art 21 is located in any of the exhibition areas 31, and from each digital art 21 in the list obtained in step S33, the digital art 21 that can be displayed in the exhibition area 31 is determined based on the respective exhibition conditions. Objects are extracted (S34). It may be possible to display all items that match exhibition conditions such as exhibition period and exhibition location, or it may be possible to display a predetermined number of items that are most popular or new items.

Note that when determining whether or not the user 4 is located within any of the exhibition areas 31, as described above, for example, latitude and longitude information obtained by GPS may be used, or the user terminal 41 may use latitude and longitude information. The identification information of the received beacon signal may also be used. If there is no digital art 21 located in any of the exhibition areas 31 or if there is no digital art 21 that can be displayed in the existing exhibition area 31, the process ends.

When the information on the digital art 21 that can be exhibited is acquired in step S34, the exhibition conditions for each digital art 21 (information on markers that specify the exhibition location, display size, orientation, and other display settings) are obtained from the exhibition condition DB 15. information, etc.) and responds this to the user terminal 41 (S35).

The user terminal 41 uses a dedicated application for AR display to display an image of the exhibition area 31 at a location specified by a marker specified in the exhibition conditions according to the display settings specified in the exhibition conditions. The digital art 21 is displayed in AR (S36). Thereby, the user 4 can view and appreciate the digital art 21 displayed by AR display in a manner that matches the situation of the exhibition area 31 being photographed by the user terminal 41. You can also purchase it from the marketplace if you wish. Note that which digital art 21 to display in AR at the location specified by the marker in the exhibition area 31 may be fixedly set in advance by the exhibitor 3 in the exhibition condition DB 15, or may be set in advance by the exhibitor 3 depending on the time of day. The exhibition processing unit 13 may use AI or the like to dynamically determine the location based on the user's 4 attributes including the season, weather, and destination.
