DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0023] 1 shows a system according to an embodiment of the present invention. A mobile terminal 100 used by an NFT holder communicates with a first device 110, a second device 120 different from the first device 110, a blockchain network 130, and a storage 140 via an IP network such as the Internet. The blockchain network 130 includes multiple nodes, and the mobile terminal 100 communicates with any of the nodes.

[0024] The mobile terminal 100 includes a communication unit 101 such as a communication interface, a processing unit 102 such as a processor or a CPU, and a storage unit 103 including a storage device or storage medium such as a memory or a hard disk, and can be configured by executing a program for performing each process or operation in at least one processor of the processing unit 102. The mobile terminal 100 can be a portable device such as a smartphone or a tablet that can be connected to an IP network by wireless communication. The program may include one or more programs, and may be recorded in a computer-readable storage medium to form a non-transient program product. The program may be stored in the storage unit 103, and instructions included in the program may be executed in at least one processor of the processing unit 102, and the program may also be transmitted from the first device 110 to the mobile terminal 100 as described below.

[0025] First, the mobile terminal 100 receives a module for a camera application from the first device 110 (S201). FIG. 3 is an example of a screen 300 displayed on a web browser operating on the mobile terminal 100 when the module is executed on the mobile terminal 100. The module can be written in, for example, JavaScript (registered trademark) language. An example of a camera application provided using a web browser will be described below, but a native application may be installed on the mobile terminal 100. In this case, the mobile terminal 100 receives the native application from the first device 110 in advance. In either case, the mobile terminal 100 only needs to receive a program for the camera application from the first device 110.

[0026] Next, the mobile terminal 100 transmits a request to the second device 120 different from the first device 110 to connect the software wallet to the camera application (S202). The software wallet must be installed in the mobile terminal 100 and the public address must be registered. The software wallet may be a native application or a plug-in for a web browser.

[0027] For example, in the example of screen 300 shown in Fig. 3, in response to the user of the mobile terminal 100 clicking or tapping a button labeled "Connect Wallet", a selection screen for a wallet to be connected may be displayed on the display screen of the mobile terminal 100, and a request may be made to the second device 120 providing the wallet connection service to connect the wallet selected by the user to the camera application. Here, "connecting" a wallet means that the application to be connected is able to view the public address and data associated therewith managed in the wallet to be connected.

[0028] Then, the mobile terminal 100 receives a notification of successful connection from the second device 120 via the first device 110 as necessary (S203). Here, an example is described in which the wallet connection service provided by the second device 120 is used, but other methods may be used as long as the software wallet installed in the mobile terminal 100 can be connected to the camera application. Also, instead of the second device 120 notifying the user of the successful connection, the software wallet may notify the camera application on the mobile terminal 100, and no explicit notification may be given.

[0029] After the connection, the mobile terminal 100 receives one or more URLs of one or more images included in at least any metadata of one or more NFTs associated with the public address managed by the software wallet from the blockchain network 130 in which the public address is recorded (S204 to S205). Although the expression "URL" is used, any information indicating a storage location on an IP network may be used. The blockchain network 130 may be an Ethereum (trademark) blockchain network or an EVM compatible network.

[0030] Specifically, as an example, a contract address capable of issuing NFTs targeted by a camera application is stored in the camera application, and the number n of NFTs issued using the contract address is obtained by the web3.js method tokenSupply(). If the tokenid identifying an NFT is incremented from 0, it is possible to check which public address holds each NFT by invoking the method ownerOf(tokenid) for tokenids 0 to n-1. An NFT identified by a tokenid whose return value of the method ownerOf(tokenid) matches a public address managed by a software wallet connected to the camera application can be identified as an NFT associated with that public address. Then, for each NFT identified in this way, the method tokenURI(tokenid) can be invoked to find the URL of the image included in the metadata of the NFT.

[0031] The URL of the image linked to the NFT associated with the public address managed by the software wallet may be obtained by storing an association between multiple NFT identifiers such as tokenids and the URLs of images linked to the NFTs identified by each NFT identifier in a storage device or storage medium accessible by the mobile terminal 100 and referencing this.

[0032] The mobile terminal 100 can obtain the images stored in the received one or more URLs by accessing those URLs (S206 to S207). The metadata of each NFT is, for example, data in JSON format, and includes the URL of the image, and may further include the name and description of the image. The URL can be a URL that includes an identifier of the content in the distributed storage. If the identifier is a hash value of the image, if there is tampering after the NFT is issued, the hash value will not match the identifier, making it possible to verify whether or not there has been tampering. An example of an image to be obtained is an image that includes one or more people or buildings.

[0033] Then, as shown in the list screen 400 of FIG. 4, at least a part of the acquired one or more images is displayed on the camera application (S208), and in response to the selection of one of the images by the NFT holder, who is the user of the mobile terminal 100, it becomes possible to shoot a video using the image as a camera frame (S209). Here, displaying at least a part of the acquired one or more images includes displaying them as previews such as thumbnails corresponding to the images. In addition, the display may be performed after rearranging the images based on the past selections of the NFT holder in order to reflect the preferences of the NFT holder. In the example of the shooting screen 500 shown in FIG. 5, it is possible to take a photo, but it may also be possible to shoot a video. In addition, it may be possible to change the image used as the camera frame from the screen where shooting is possible.

[0034] In this way, by connecting a software wallet installed on the mobile terminal 100 to a camera application running on the mobile terminal 100 used by the holder of one or more NFTs, and enabling the holder to take a video using an image selected by the holder from one or more images linked to one or more NFTs associated with a public address managed by the software wallet as a camera frame, the holder can be given a new experience that can be obtained by holding an NFT due to the rarity of the NFT to which the image is linked. By linking collected NFTs with the familiar act of explaining photos or videos, the benefits of holding NFTs can be realized, increasing interest in NFTs.

[0035] The image displayed on the camera application may be an image linked to one or more NFTs associated with the public address that meet certain conditions. For example, by displaying an image on the camera application as an image that can be selected only at a certain location or date and time, the value of the experience given to the holder of the NFT linked to the image can be increased. Examples of such images include images showing events such as fireworks and festivals, and images showing tourist attractions. In addition, only images linked to one or more NFTs associated with the public address that meet certain conditions may be selectable from among the displayed images.

[0036] In the above-mentioned embodiments, it should be noted that unless there is a statement of "only" such as "based only on", "depending only on", or "only in the case of", it is assumed in this specification that additional information may be taken into consideration. Also, as an example, it should be noted that the statement "do b when a" does not necessarily mean "always do b when a" or "do b immediately after a" unless expressly stated. Also, the statement "each a constituting A" does not necessarily mean that A is composed of multiple components, but includes the case where the component is singular.

[0037] Also, just to be clear, even if there is an aspect of a method, program, terminal, device, server or system (hereinafter referred to as a "method, etc.") that performs an operation different from that described in this specification, each aspect of the present invention is directed to an operation that is the same as any of the operations described in this specification, and the existence of an operation different from that described in this specification does not make the method, etc. outside the scope of each aspect of the present invention.
