Description

Terminal and method

[0001] One aspect of the present invention relates to a terminal and a method.

[0002] Patent Document 1 describes a mobile communication system including a small portable display device and a mobile phone device. In this system, information stored in the mobile phone device is transmitted to the small portable display device, and the received information is displayed on the small portable display device.

[0003] Japanese Patent Application Laid-Open No. 2003-78965

[0004] In such a system, it is conceivable that a user other than the owner of the image representing the NFT may display the image representing the NFT on a small portable display device. In this case, the security of the image representing the NFT may be compromised. Therefore, it is desirable to display the image representing the NFT on a small portable display device while maintaining the security of the image representing the NFT.

[0005] One aspect of the present invention has been made in consideration of the above-mentioned situation, and aims to provide a terminal and method that enable an image indicating an NFT to be displayed on another terminal while maintaining the security of the image indicating an NFT.

[0006] In order to achieve the above object, the terminal of the present invention is a terminal configured to be able to input and output information to and from other terminals, and is equipped with an input unit that inputs information regarding an image showing an NFT, information regarding the owner of the NFT, and owner information regarding at least one of the owner of the terminal and the owner of the other terminal, and a control unit that, when it is determined based on the information regarding the owner of the NFT and the owner information that the owner of the NFT matches at least one of the owner of the terminal and the owner of the other terminal, transmits information regarding the image showing the NFT and permission information to permit the display of the image showing the NFT to the other terminal.

[0007] In the terminal according to the present invention, when the owner of the NFT matches at least one of the owner of the terminal and the owner of another terminal, information about an image representing the NFT and permission information for permitting the display of the image representing the NFT are transmitted to the other terminal. This configuration can prevent users other than the owner of the NFT from displaying the NFT on other terminals. This makes it possible to display the image representing the NFT on other terminals while maintaining the security of the image representing the NFT.

[0008] According to one aspect of the present invention, it is possible to display an image showing an NFT on another terminal while maintaining the security of the image showing an NFT.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0011] 1 is a diagram for explaining an overview of processing in an apparatus according to an embodiment. As shown in FIG. 1, an image display system 100 includes a first terminal 10 (terminal) and a second terminal 20 (another terminal). The first terminal 10 is configured to be able to input and output information to and from the second terminal 20.

[0012] The first terminal 10 according to the embodiment acquires an image showing an NFT from the network NW. If the owner of the NFT matches the owner of the first terminal 10, the first terminal 10 transmits information about the image showing the NFT and permission information for permitting the display of the image showing the NFT to the second terminal 20. Finally, the second terminal 20 displays information about the image showing the NFT based on the permission information.

[0013] An NFT (Non-Fungible Token) is a non-fungible token and a type of digital asset created using blockchain technology. Each NFT has an assigned owner. Information regarding the assignment of the owner of each NFT is certified on the blockchain. In this embodiment, the NFT is mainly image data. For example, the image representing the NFT is an image of a character or idol. The network NW is an NFT market such as OpenSea or Miime.

[0014] The information about the image representing the NFT is information about the image content of the NFT. The information about the image representing the NFT may be an image file representing the NFT, a video file representing the NFT, or information representing an NFT image file. The information representing the NFT image file may be any information for identifying the file, such as a file name or a file identification number.

[0015] The first terminal 10 is a terminal held by a user. The first terminal 10 is, for example, a smartphone or a tablet terminal carried by the user. The first terminal 10 is capable of communicating with the second terminal 20 via short-range wireless communication. An example of short-range wireless communication is Bluetooth (registered trademark).

[0016] The second terminal 20 is a small terminal owned by the user. FIGS. 2( a), (b), and (c) are diagrams illustrating examples of the second terminal 20. In the example illustrated in FIG. 2( a), the second terminal 20 is a badge-type display terminal. Multiple second terminals 20 are attached to a bag B. In the example illustrated in FIG. 2( b), the second terminal 20 is a keychain-type display terminal. In the example illustrated in FIG. 2( c), the second terminal 20 is a card-type display terminal placed inside a smartphone case. In FIGS. 2( a), (b), and (c), the second terminal 20 displays an image of a character or idol favored by the user in a display area D. The display area D is configured, for example, with electronic paper capable of displaying full-color images. For example, when participating in an event such as a live concert, the user can use the second terminal 20 to show other participants which character or idol the user favors. In other words, the second terminal 20 is a product used in so-called "oshikatsu" (supporting a favorite character or idol).

[0017] In this case, in the example shown in Figure 2(a), compared to the case where badges are used, by using a badge-type display terminal, the type of character to be displayed and the arrangement of the characters can be easily changed simply by switching the display on the display terminal. In the examples shown in Figures 2(b) and 2(c), by using a card-type display terminal, the type of character to be displayed and the arrangement of the characters can be easily changed simply by switching the display on the display terminal. Displaying ticket information on the display terminal can also improve user convenience.

[0018] The image representing the NFT on the second terminal 20 may be changed depending on the amount the user has paid for each content item (e.g., the number of years of fan club membership, the amount of merchandise purchased, etc.) (for example, the display mode of the image representing the NFT may be changed by applying hologram processing or the like to the image representing the NFT). In this case, the fan club operator can simply send the image representing the NFT online, eliminating the need to send a physical membership card, thereby easily improving the user's experience of supporting their favorite fan. An image representing the same NFT may also be distributed when a physical membership card is purchased.

[0019] 3 is a block diagram showing the functional configuration of the first terminal 10 and the second terminal 20 of the image display system 100. The first terminal 10 has an input unit 11 and a control unit 12. The second terminal 20 has a transmission unit 21, a reception unit 22, and a display unit 23. Each functional unit of the first terminal 10 and the second terminal 20 will be described in detail below.

[0020] The input unit 11 inputs information about an image showing an NFT and information about the owner of the NFT to the control unit 12. Specifically, the input unit 11 acquires the information about the image showing an NFT and the information about the owner of the NFT from the network NW shown in FIG. 1 or a storage unit (not shown). The input unit 11 inputs the acquired information to the control unit 12.

[0021] The information about the owner of the NFT is information about the user who owns the NFT. The information about the user who owns the NFT may be any information that can identify the user. For example, the information about the user who owns the NFT may be any one or combination of user identification information, username, name, and telephone number. The information about the owner of the NFT may be information about a device (e.g., the first terminal 10 or the second terminal 20) owned by the owner of the NFT. For example, the information about the device owned by the owner of the NFT may be the device identification number or the device serial number, etc.

[0022] The input unit 11 inputs owner information related to at least one of the owner of the first terminal 10 and the owner of the second terminal 20 to the control unit 12. Specifically, in the first terminal 10, first owner information related to the owner of the first terminal 10 is set in advance and stored in the storage unit. The input unit 11 acquires the first owner information from the storage unit and inputs the first owner information to the control unit 12. The input unit 11 also acquires information related to the owner of the second terminal 20 from the second terminal 20 and inputs the second owner information to the control unit 12.

[0023] The owner information regarding at least one of the owner of the first terminal 10 and the owner of the second terminal 20 is information regarding at least one of the user who owns the first terminal 10 and the user who owns the second terminal 20, for example, information indicating the user who owns the first terminal 10 or the second terminal 20. As one example, the information indicating the user who owns the first terminal 10 or the second terminal 20 may be any one or combination of user identification information, user name, name, and telephone number. As another example, the information indicating the user who owns the first terminal 10 or the second terminal 20 may be the identification number or serial number of the first terminal 10 or the second terminal 20.

[0024] The input unit 11 inputs distance information relating to the distance between the first terminal 10 and the second terminal 20 to the control unit 12. Specifically, the input unit 11 transmits a beacon to the second terminal 20 that is paired with the first terminal 10 via Bluetooth (registered trademark) or the like, and calculates information indicating the distance between the first terminal 10 and the second terminal 20 based on a response from the second terminal 20. For example, the input unit 11 calculates information indicating the time from the time the beacon is transmitted to the time the response is received from the second terminal 20. The input unit 11 inputs the calculated information to the control unit 12.

[0025] When the control unit 12 determines, based on the information about the owner of the NFT and the owner information, that the owner of the NFT matches at least one of the owner of the first terminal 10 and the owner of the second terminal 20, the control unit 12 transmits information about the image showing the NFT and permission information to the second terminal 20. Specifically, when the control unit 12 determines, based on the information about the owner of the NFT and the owner information, that the owner of the NFT matches both the owner of the first terminal 10 and the owner of the second terminal 20, the control unit 12 transmits information about the image showing the NFT and permission information to the second terminal 20.

[0026] The permission information is information for permitting the display of an image representing an NFT. Specifically, the permission information may be any information that enables the display of an image representing an NFT. For example, the permission information may be a token indicating permission to display an image representing an NFT. The permission information may be key information used to display an image representing an NFT. As an example, if an image file of an NFT is encrypted with an encryption key, the permission information may be a decryption key. The permission information may also be information other than the above.

[0027] The permission information includes information indicating an expiration date. If the expiration date has passed, information related to an image showing an NFT cannot be displayed based on the permission information. For example, if the second terminal 20 cannot periodically obtain the permission information, the second terminal 20 cannot display an image showing an NFT. Note that when the second terminal 20 starts displaying an image showing an NFT based on the permission information, the control unit 12 transmits the next permission information to the second terminal 20 within the expiration date. This allows the second terminal 20 to continue displaying the image showing an NFT.

[0028] The control unit 12 may transmit information related to the image indicating the NFT and permission information to the second terminal 20 based on the distance information. Specifically, when the control unit 12 further determines that the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold, the control unit 12 may transmit information related to the image indicating the NFT and permission information to the second terminal 20. For example, when the control unit 12 determines that the time from when the input unit 11 transmits a beacon to the second terminal 20 to when the control unit 12 receives a response from the second terminal 20 is equal to or less than a threshold, the control unit 12 may transmit information related to the image indicating the NFT and permission information to the second terminal 20. The threshold may be set in advance by the owner of the NFT, etc.

[0029] The control unit 12 may stop displaying information related to an image indicating an NFT on the second terminal 20 based on the distance information. Specifically, when the control unit 12 determines that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold, the control unit 12 may stop displaying information related to an image indicating an NFT on the second terminal 20. For example, when the control unit 12 determines that the time from when the input unit 11 transmits a beacon to the second terminal 20 to when the control unit 12 receives a response from the second terminal 20 exceeds a threshold, the control unit 12 may stop displaying information related to an image indicating an NFT on the second terminal 20.

[0030] When the control unit 12 determines that the first terminal 10 cannot communicate with the second terminal 20, the control unit 12 may stop displaying information related to the image indicating the NFT on the second terminal 20. Furthermore, when the control unit 12 determines that the first terminal 10 cannot communicate with the second terminal 20 for a predetermined period of time, the control unit 12 may invalidate information related to the owner of the second terminal 20.

[0031] When the control unit 12 determines that the owner of the NFT has changed based on the information about the owner of the NFT, the control unit 12 may stop displaying information about the image showing the NFT on the second terminal 20. Specifically, when the control unit 12 determines that the owner of the NFT does not match the owner of the first terminal 10 based on the information about the owner of the NFT and the owner information, the control unit 12 may stop displaying information about the image showing the NFT on the second terminal 20.

[0032] When the control unit 12 stops displaying information related to an image showing an NFT on the second terminal 20, it either stops sending permission information to the second terminal 20 or sends stop information to the second terminal 20 to stop displaying information related to an image showing an NFT.

[0033] Next, each functional unit of the second terminal 20 will be described. The transmitter 21 acquires information about the owner of the second terminal 20 from a storage unit (not shown). The transmitter 21 transmits information about the owner of the second terminal 20 to the first terminal 10. The transmitter 21 transmits a response to the beacon transmitted from the first terminal 10 to the first terminal 10. The receiver 22 receives information about an image indicating an NFT and permission information from the first terminal 10. The receiver 22 outputs the received information to the display unit 23. The display unit 23 displays information about the image indicating an NFT based on the permission information. When the user deletes information about the owner of the second terminal 20, the user inputs a password set in advance.

[0034] Next, a process for displaying an image showing an NFT will be described with reference to Figures 4 to 6. Figure 4 is a flowchart showing a process for displaying an image showing an NFT.

[0035] 4 , the first terminal 10 confirms a communication connection between the first terminal 10 and the second terminal 20 (step S101). For example, the first terminal 10 and the second terminal 20 are paired by Bluetooth or the like. When the first terminal 10 and the second terminal 20 are connected for communication for the first time, a dedicated app or the like installed on the first terminal 10 confirms that an owner has not been set for the second terminal 20, and newly registers information indicating the owner of the first terminal 10 in the second terminal 20.

[0036] Next, the first terminal 10 inputs information indicating an image related to the NFT, information related to the owner of the NFT, and owner information related to at least one of the owner of the first terminal 10 and the owner of the second terminal 20 (step S102: input step). Specifically, the first terminal 10 acquires the information indicating an image related to the NFT and the information related to the owner of the NFT from a network or a storage unit. The first terminal 10 acquires information related to the owner of the first terminal 10 from the storage unit. The first terminal 10 acquires information related to the owner of the second terminal 20 from the second terminal 20.

[0037] Next, if the first terminal 10 determines, based on the information about the NFT owner and the owner information, that the owner of the NFT matches at least one of the owner of the first terminal and the owner of the second terminal, it transmits information about the image showing the NFT and permission information from the first terminal 10 to the second terminal 20 (step S103: control step). Specifically, if the first terminal 10 determines, based on the information about the NFT owner and the owner information, that the owner of the NFT matches both the owner of the first terminal 10 and the owner of the second terminal 20, it transmits information about the image showing the NFT and permission information to the second terminal 20 (steps S131 and S132 described below).

[0038] The processing of step S103 will be described in detail below. FIG. 5 is a diagram illustrating an example of the processing of step S103. As illustrated in FIG. 5, the first terminal 10 determines whether the owner of the NFT and the owner of the first terminal 10 match based on information about the owner of the NFT and the owner information (step S131). Subsequently, if the first terminal 10 determines that the owner of the NFT and the owner of the first terminal 10 match (step S131: YES), the first terminal 10 determines whether the owner of the first terminal 10 and the owner of the second terminal 20 match based on the owner information (step S132). If the first terminal 10 determines that the owner of the first terminal 10 and the owner of the second terminal 20 match (step S132: YES), the first terminal 10 determines whether the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold based on the distance information (step S133). If the first terminal 10 determines that the distance between the first terminal 10 and the second terminal 20 is less than or equal to a threshold value (step S133: YES), it sends information about the image indicating the NFT and permission information to the second terminal 20, terminates the processing of step S103, and proceeds to step S104 (step S134).

[0039] If the first terminal 10 determines that the owner of the NFT does not match the first terminal 10 (step S131: NO), if the owner of the first terminal 10 does not match the owner of the second terminal 20 (step S132: NO), or if it determines that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold value (step S133: NO), it terminates the processing of step S103 and terminates the processing of displaying the image without proceeding to step S104.

[0040] Finally, the second terminal 20 displays information about the image showing the NFT (step S104). Specifically, the second terminal 20 receives information about the image showing the NFT and permission information from the first terminal 10, and displays information about the image showing the NFT based on the permission information.

[0041] 6 is a flowchart showing the process after the image showing the NFT is displayed. After the image showing the NFT is displayed, the process shown in FIG. 6 is repeatedly executed at a predetermined interval. As shown in FIG. 6, the first terminal 10 determines whether the owner of the NFT has changed based on information about the owner of the NFT (step S201). Specifically, the first terminal 10 determines whether the owner of the NFT matches the owner of the first terminal 10.

[0042] If the first terminal 10 determines that the owner of the NFT has not changed based on the information about the owner of the NFT (step S201: YES), it determines whether the owner of the first terminal 10 matches the owner of the second terminal 20 (step S202). In step S202, the first terminal 10 determines (confirms) whether the owner registered in a dedicated app or the like installed on the first terminal 10 matches the owner stored on the second terminal 20. The above determination process is executed by a dedicated app or the like installed on the first terminal 10.

[0043] If the first terminal 10 determines that the owner of the first terminal 10 and the owner of the second terminal 20 are the same (step S202: YES), the first terminal 10 determines whether the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold (step S203). If the first terminal 10 determines that the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold (step S203: YES), the first terminal 10 determines whether the first terminal 10 and the second terminal 20 are capable of communicating with each other (step S204). If the first terminal 10 determines that the first terminal 10 and the second terminal 20 are capable of communicating with each other (step S204: YES), the first terminal 10 transmits permission information to the second terminal 20 (step S205). Therefore, when the second terminal 20 starts displaying information related to an image showing an NFT based on the permission information, the first terminal 10 transmits the next permission information to the second terminal 20 within a predetermined period (within the expiration date).

[0044] If the first terminal 10 determines that the owner of the NFT has changed based on information about the owner of the NFT (step S201: NO), if it determines that the owner of the first terminal 10 does not match the owner of the second terminal 20 (step S202: NO), if it determines that the distance between the first terminal and the second terminal exceeds a threshold (step S203: NO), or if it determines that the first terminal 10 and the second terminal 20 are not able to communicate (step S204: NO), it stops displaying information about the image showing the NFT on the second terminal (step S205).

[0045] Next, the effects of the first terminal 10 according to the present embodiment will be described. With the first terminal 10 and method according to the present embodiment, when the owner of the NFT matches at least one of the owner of the first terminal 10 and the owner of the second terminal 20, information about an image showing the NFT and permission information for permitting the display of the image showing the NFT are transmitted to the second terminal 20. This configuration can prevent users other than the owner of the NFT from displaying the NFT on the second terminal 20. This makes it possible to display an image showing the NFT on the second terminal 20 while maintaining the security of the image showing the NFT.

[0046] In the first terminal 10, the owner information may be information about the owner of the first terminal 10 and the owner of the second terminal 20, and when the control unit 12 determines, based on the information about the owner of the NFT and the owner information, that the owner of the NFT matches both the owner of the first terminal 10 and the owner of the second terminal 20, it may transmit information about the image indicating the NFT and permission information to the second terminal 20. In this case, when the owner of the NFT matches the owner of the first terminal 10 and the owner of the second terminal 20, information about the image indicating the NFT and permission information for permitting the display of the image indicating the NFT are transmitted to the second terminal 20. This makes it possible to display the image indicating the NFT on the second terminal 20 while more reliably maintaining the security of the image indicating the NFT.

[0047] In the first terminal 10, the input unit 11 may further input distance information regarding the distance between the first terminal 10 and the second terminal 20, and the control unit 12 may transmit information regarding the image indicating the NFT and permission information to the second terminal 20 when it further determines, based on the distance information, that the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold. In this case, when the owner of the NFT matches the owner of the first terminal 10 and the owner of the second terminal 20, and the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold, information regarding the image indicating the NFT can be displayed on the second terminal 20. This makes it possible to display the image indicating the NFT on the second terminal 20 while more reliably maintaining the security of the image indicating the NFT.

[0048] In the first terminal 10, when the control unit 12 determines that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold based on the distance information, the control unit 12 may stop displaying information related to the image indicating the NFT on the second terminal 20. In this case, when the user does not have the second terminal 20, for example, when the second terminal 20 is lost or stolen, the display of the image indicating the NFT on the second terminal 20 can be stopped. As a result, the security of the NFT can be maintained more reliably.

[0049] In the first terminal 10, when it is determined that the owner of the NFT has changed based on the information about the owner of the NFT, the control unit 12 may stop displaying information about the image showing the NFT on the second terminal 20. In this case, when the owner of the NFT has changed based on the information about the owner of the NFT, it is possible to stop displaying the image showing the NFT on the second terminal 20. As a result, it is possible to prevent users other than the owner of the NFT from displaying the image showing the NFT on the second terminal 20. Therefore, the security of the NFT can be maintained more reliably.

[0050] In the first terminal 10, the permission information may include information indicating an expiration date of the permission information, and when the second terminal 20 starts displaying information related to an image showing an NFT based on the permission information, the control unit 12 may transmit the next permission information to the second terminal 20 within the expiration date. In this case, the first terminal 10 can continue to display information related to an image showing an NFT on the second terminal 20 by continuing to transmit the permission information to the second terminal 20. The first terminal 10 can stop displaying information related to an image showing an NFT on the second terminal 20 by stopping transmission of the permission information to the second terminal 20.

[0051] In the above embodiment, the owner information is information about the owner of the first terminal 10 and the owner of the second terminal 20, but is not limited thereto. For example, in the first terminal 10, the owner information may be information about the owner of the first terminal 10, and when the control unit 12 determines that the owner of the NFT and the owner of the first terminal 10 match based on the information about the owner of the NFT and the owner information, the control unit 12 may transmit information about the image representing the NFT and permission information to the second terminal 20. In this case, in the processing of step S103 shown in FIG. 5 , step S132 may not be executed. When the first terminal 10 determines that the owner of the NFT and the owner of the first terminal 10 match (step S131: YES), the first terminal 10 proceeds to step S133.

[0052] In this case, if the owner of the NFT and the owner of the first terminal 10 match, information about the image showing the NFT and permission information for permitting the display of the image showing the NFT are transmitted to the second terminal 20. This makes it possible to prevent users other than the owner of the NFT from displaying the NFT on the second terminal 20. As a result, it becomes possible to display the image showing the NFT on the second terminal 20 while maintaining the security of the image showing the NFT.

[0053] Furthermore, for example, the owner information may be information about the owner of the second terminal 20, and when the control unit 12 determines that the owner of the NFT and the owner of the second terminal 20 match based on the information about the owner of the NFT and the owner information, the control unit 12 may transmit information about the image indicating the NFT and the permission information to the second terminal 20. In this case, in the processing of step S103 shown in FIG. 5 , instead of steps S131 and S132, it may be determined whether the owner of the NFT and the owner of the second terminal 20 match based on the information about the owner of the NFT and the owner information. When the first terminal 10 determines that the owner of the NFT and the owner of the second terminal 20 match, the first terminal 10 proceeds to step S133.

[0054] In this case, if the owner of the NFT and the owner of the second terminal 20 match, information about the image representing the NFT and permission information for permitting the display of the image representing the NFT are transmitted to the second terminal 20. This makes it possible to prevent users other than the owner of the NFT from displaying the NFT on the second terminal 20. As a result, it becomes possible to display the image representing the NFT on the second terminal 20 while maintaining the security of the image representing the NFT.

[0055] In the above embodiment, the first terminal 10 transmitted permission information to the second terminal 20 at a predetermined period, but the second terminal 20 may periodically request permission information from the first terminal 10, and the first terminal 10 may execute the process shown in Figure 6 in response to the request and transmit the permission information to the second terminal 20.

[0056] In the above embodiment, the first terminal 10 has the input unit 11 and the control unit 12. However, the second terminal 20 may have the input unit 11 and the control unit 12. For example, the second terminal 20 (terminal) may be a terminal configured to be able to input and output information to and from the first terminal 10 (another terminal). The input unit 11 may input information about an image representing an NFT, information about the owner of the NFT, and owner information about at least one of the owner of the first terminal 10 and the owner of the second terminal 20 to the control unit 12. The control unit 12 may display information about the image representing the NFT when it determines that the owner of the NFT matches at least one of the owner of the first terminal 10 and the owner of the second terminal 20 based on the information about the owner of the NFT and the owner information. The control unit 12 may request permission information from the network or the first terminal 10 and input the received permission information to the display unit 23. The display unit 23 may display information about the image representing the NFT based on the permission information.

[0057] In this case, if the owner of the NFT matches at least one of the owner of the terminal and the owner of the other terminal, information about an image representing the NFT is displayed on the second terminal 20 (terminal). This configuration can prevent users other than the owner of the NFT from displaying the NFT on the second terminal 20 (terminal). This makes it possible to display an image representing the NFT on the second terminal 20 (terminal) while maintaining the security of the image representing the NFT.

[0058] In the above embodiment, when the control unit 12 determines, based on the information about the owner of the NFT and the owner information, that the owner of the NFT matches at least one of the owner of the first terminal 10 and the owner of the second terminal 20, the control unit 12 may instruct the second terminal 20 to display information about an image representing the NFT by streaming. For example, the control unit 12 may receive information about images representing multiple NFTs and control the second terminal 20 to sequentially display the images representing the multiple NFTs.

[0059] In this case, if the owner of the NFT matches at least one of the owner of the terminal and the owner of the other terminal, information related to the image showing the NFT is displayed on the second terminal 20. Furthermore, if the communication connection between the first terminal 10 and the second terminal 20 is disconnected, the display of information related to the image showing the NFT stops. This configuration can prevent users other than the owner of the NFT from displaying the NFT on the second terminal 20. This makes it possible to display the image showing the NFT on the second terminal 20 while maintaining the security of the image showing the NFT.
