The communication unit 28 includes an interface for communicating information with the server 102 via the information communication network 108 . Communication by the communication unit 28 may be wired or wireless.

The server 102 and the user terminal 104 can be, for example, personal computers (PCs), smart phones, tablet terminals, and the like.

The moving body 106 has moving means that enables movement. The mobile body 106 can be, for example, a drone that can move by flying, a robot that can move by walking or running, or the like. Mobile object 106 is placed at a place where digital objects are distributed, such as an event venue. The movement of the mobile body 106 may be autonomously performed based on a preset movement schedule, or may be controlled by an external device such as the server 102 or the like.

In this embodiment, as shown in FIG. 4, a code 30 is affixed to the outer surface of the mobile body 106, and the code 30 is read by the input unit 24 of the user terminal 104, thereby sending a digital message from the server 102 to the user terminal 104. It becomes possible to participate in distribution events of NFT objects for items. The code 30 may be a two-dimensional QR code (registered trademark), a one-dimensional code, or a three-dimensional code.

In this embodiment, an example using the moving body 106 is shown, but the code 30 may be attached to a predetermined place such as a wall or a pillar of an event venue without using the moving body 106. .

Digital object distribution processing according to the embodiment of the present invention will be described below with reference to the flowchart of FIG. Digital object distribution processing is implemented by running a digital object distribution program on server 102 and a user terminal program on user terminal 104 .

In step S10, control for moving the moving body 106 is performed. Through the processing in this step, the digital object distribution system 100 functions as movement control means. The moving body 106 starts moving such as flying autonomously or under the control of an external device such as the server 102 .

Mobile object 106 is preferably moved, for example, at a venue such as an event where digital objects are distributed. By using the mobile 106, the attention of users in the vicinity of the mobile 106 can be drawn. Participation in the distribution of digital objects, which will be described later, can thereby be induced.

It should be noted that the moving body 106 may be used to distribute physical distribution items such as goods and pamphlets. In addition, the moving object 106 may output still images, moving images, audio, and the like. As a result, the user's interest in the moving object 106 can be further attracted.

In step S12, processing for satisfying participation conditions by the user terminal 104 is performed. Through the processing in this step, the digital object distribution system 100 functions as participation processing means. In this embodiment, the user uses the input unit 24 of the user terminal 104 to read the code 30 attached to the mobile object 106 . The user terminal 104 transmits the read code 30 information to the server 102 via the communication unit 28 .

Although the condition for participation in the event is that a code is provided on the mobile body 106 and the code is read by the user terminal 104, the condition is not limited to this. For example, the participation condition may be that the user terminal 104 is within a predetermined area such as a venue where the event is being held. In this case, the user terminal 104 may be provided with position specifying means such as GPS to acquire the position of the user terminal 104 . Further, the participation condition may be that a beacon is generated in a predetermined area such as a hall where an event is held and the user terminal 104 receives the beacon. In this case, the user terminal 104 may be provided with beacon receiving means to receive the beacon from the user terminal 104 .

In step S14, a process of associating an electronic wallet for managing the NFT object with the user terminal 104 is performed. Through the processing in this step, the digital object distribution system 100 functions as wallet setting means. When receiving the code 30 information from the user terminal 104, the server 102 determines whether or not the code 30 information satisfies the participation conditions of the event. If the information of code 30 does not satisfy the conditions for participation in the event, it waits for the transmission of information satisfying the conditions for participation from the user terminal 104 . If the information of code 30 satisfies the conditions for participation in the event, processing is performed to associate an electronic wallet for managing the NFT object with the user terminal 104 of the transmission source.

If an electronic wallet has not been generated for the user terminal 104 of the transmission source, the server 102 automatically generates an electronic wallet and associates it with the user terminal 104 of the transmission source. For example, the server 102 automatically generates an electronic wallet that can record the ownership and transaction history of NFT objects based on standards such as ERC-721 and ERC-1155, and an identifier (address, etc.) that identifies the user terminal 104 that is the sender. ). If an electronic wallet has already been generated for the user terminal 104 of the transmission source, processing is performed to obtain information on the existing electronic wallet and associate the electronic wallet with the user terminal 104 of the transmission source.

In this way, when an electronic wallet is not associated with the user terminal 104 of the transmission source, the user can easily receive the NFT object by automatically generating an electronic wallet and associating it with the user terminal 104 of the transmission source. .

The electronic wallet is preferably made available from a web browser on the source user terminal 104 . That is, a web browser is preferably used to allow access to information regarding the electronic wallet associated with the user terminal 104 . This makes it possible to access the electronic wallet without installing a dedicated application or the like on the user terminal 104 . A dedicated electronic wallet application may be installed in the user terminal 104 .

In step S16, a process for causing the user terminal 104 to perform a predetermined operation is performed. Through the processing in this step, the digital object distribution system 100 functions as service providing means. After performing the wallet setting process in step S14, the server 102 transmits to the user terminal 104 information necessary for providing a service for the user to perform a predetermined operation using the user terminal 104 via the communication unit 18. . When the user terminal 104 receives the information from the server 102 via the communication unit 28, the user terminal 104 performs processing for performing a predetermined operation.

In this embodiment, an augmented reality image (AR image) including an image corresponding to a digital object to be distributed is displayed on the output unit 26 of the user terminal 104 (digital object display means). For example, as shown in FIG. 6, the camera, which is the input unit 24 of the user terminal 104, continues to capture images of the moving object 106, so that the display, which is the output unit 26 of the user terminal 104, is made to look like a balloon 32. display an image. Furthermore, an AR image 200 in which an image corresponding to the seed 34, which is a digital object to be distributed, is scattered from the balloon 32 is displayed.

In step S18, a process of accepting an operation by the user terminal 104 is performed. Through the processing in this step, the digital object distribution system 100 functions as operation acquisition means. The user uses the user terminal 104 to perform an operation that satisfies the necessary operation conditions to receive the distribution of the digital object. Information indicating the operation performed on the user terminal 104 is transmitted to the server 102 via the communication unit 28 .

In this embodiment, the operation condition is that the user uses the input unit 24 of the user terminal 104 to operate the image corresponding to the digital object included in the AR image displayed in step S16. As shown in FIG. 6, an AR image 200 is displayed in which a mobile object 106 is assumed to be a balloon 32 and seeds 34 corresponding to digital objects are scattered from the balloon 32, and the user touches the touch panel, which is the input unit 24 of the user terminal 104, to display the AR image 200. Assume that an operation of tapping the image of the seed 34 corresponding to the digital object is performed. The user terminal 104 transmits the content of the operation to the server 102 when the image of the seed 34 corresponding to the digital object is tapped.

In step S20, a process of generating an NFT object is performed. Through the processing in this step, the digital object distribution system 100 functions as NFT object generation means. When the server 102 receives the information indicating the details of the operation performed using the user terminal 104 in step S18, the server 102 determines whether or not the details of the operation satisfy the operation conditions for giving the digital object. If the operation content does not satisfy the operation condition for giving the digital object, the digital object distribution process is ended or the operation content satisfying the operation condition is received from the user terminal 104. FIG. If the operation content satisfies the operation conditions for giving a digital object, an NFT object is generated for the digital object. For example, based on standards such as ERC-721 and ERC-1155, give a unique identification code to a digital object, generate a block containing hash values indicating past transaction history information and its contents, and use it as an NFT object do.

In this embodiment, when the user terminal 104 receives an operation content indicating that the image of the seed 34 corresponding to the digital object has been tapped, the operation condition is that the image of the seed 34 corresponding to the digital object is tapped. Create an NFT object.

Note that the NFT object may be generated when other conditions are satisfied in addition to the operation conditions. For example, when some NFT object is already associated with the electronic wallet of the user terminal 104, the NFT object is generated when the operation condition is satisfied, or different digital objects are created depending on the NFT object already associated with the electronic wallet. An NFT object may be generated. As a specific example, if the electronic wallet is not already associated with an NFT object, then generate the first digital object's NFT object, and if the electronic wallet is already associated with the first digital object's NFT object, An NFT object of the second digital object may be generated.

Further, for example, when a predetermined electronic game is installed in the user terminal 104 or when the play status of the electronic game satisfies predetermined conditions, an NFT object is generated when an operation condition is satisfied, or a predetermined electronic game is played. NFT objects of different digital objects may be generated according to the installed state or the play status of the electronic game. As a specific example, if the character level is less than a predetermined value in an electronic game that is being played or has been played on the user terminal 104, the NFT object of the first digital object is generated, and if the character level is equal to or higher than the predetermined value, the NFT object is generated. An NFT object of the second digital object, if any, may be generated. In addition, if there is an item possessed in an electronic game that is being played or has been played in the user terminal 104, an NFT object is generated by using items other than the item as a digital object. An NFT object may be generated using the item as a digital object. In these cases, the digital objects are preferably items or characters that can be used in electronic games.

In step S22, a process of distributing the NFT object is performed. Through the processing in this step, the digital object distribution system 100 functions as NFT object distribution means. The server 102 distributes the NFT object by associating the NFT object generated in step S20 with the electronic wallet of the target user terminal 104.

In step S24, processing for receiving the NFT object is performed. Through the processing in this step, the digital object distribution system 100 functions as NFT object receiving means. The user terminal 104 receives information regarding the NFT object associated with the electronic wallet at step S22.

A digital object distributed as an NFT object may be, for example, an item that can be used in a virtual space. In this embodiment, by giving the digital object of the seed 34 as an NFT object to the user, the user can use the user terminal 104 to plant the digital object of the seed 34 in a flower bed in the virtual space, thereby making the flower bloom. You may make it perform the process which can be performed.

By the above processing, the user using the user terminal 104 can acquire the NFT object. The user can freely use and trade the NFT objects owned by the function of the electronic wallet.

Digital objects distributed as NFT objects may be, for example, items that can be used in services provided at event venues. As a specific example, at an event venue where digital objects are distributed as NFT objects, it may be possible to receive benefits at the event by collecting multiple types of digital objects. Digital objects distributed as NFT objects may be, for example, digital coupons that can be exchanged for prizes or the like.

Also, in the present embodiment, the operation condition for giving the NFT object is the user's operation on the AR screen, but it is not limited to this. For example, using the camera of the user terminal 104, the NFT object may be given under the operating condition that the user himself/herself takes an image of a predetermined pose or action.

Alternatively, for example, the camera of the user terminal 104 may be used to capture an image of the moving body 106, and the NFT object may be assigned using the imaging condition as an operation condition. As a specific example, the NFT object may be assigned when the size of the moving object 106 in the image by the user terminal 104 or the imaging angle of the moving object 106 satisfies a predetermined condition. Further, as a specific example, NFT objects may be assigned to different digital objects according to the size in the image of the moving body 106 by the user terminal 104 and the imaging angle of the moving body 106 .

Also, for example, an NFT object may be assigned using an operation on an external device such as an operation tool that can communicate with the user terminal 104 as an operation condition. As a specific example, an operation tool or goods available at an event venue or the like can be communicated with the user terminal 104, and the operation condition is to use the operation tool or goods, and when the operation condition is satisfied, the NFT object may be given.

Also, the digital object to be given as the NFT object may be a unique digital object such as NFT (Non-Fungible Token). For example, in step S18, a digital object such as unique video data or audio data may be automatically generated according to the operation performed using the user terminal 104 and used as an NFT object. For example, if the operation condition for giving the NFT object is that the user himself takes a predetermined pose and takes an image, unique image data is automatically generated according to the user's pose in the imaged image, and the NFT object It may be given as an object. The unique image data can be, for example, an image of a popular anime or game character taking the same pose as the user poses. Such unique digital objects can have a high added value in transactions, and can increase the motivation of users to use the digital object distribution system 100 .

Also, instead of the user terminal 104, a venue-installed terminal installed at an event venue or the like may be used. In this case, the NFT object may be assigned when the operation conditions are satisfied by the user operating the venue-installed terminal.

In addition, in the present embodiment, an example in which the server 102 and the user terminal 104 are each implemented by one device is shown, but the present invention is not limited to this, and the server 102 and the user terminal 104 are implemented by a plurality of computers. A configuration in which processing is performed in a distributed manner may also be used.
