[0004] [Patent Document 1] Patent Publication No. 2021-12620 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-288428 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a mobile terminal transmits display information including at least one of payment information and certificate information to another terminal and the other terminal displays the display information, the security of the display information may be compromised. For example, if the display information is displayed on a terminal of a user other than the user who owns the display information without the permission of the user, the security of the display of at least one of the payment information and certificate information may be compromised.

[0006] One aspect of the present invention has been made in consideration of the above-mentioned situation, and aims to provide an apparatus and method that can maintain security regarding the display of at least one of information related to payment and information related to certificates. [Means for solving the problem]

[0007] A terminal according to one embodiment of the present invention is a terminal configured to be able to input and output information to and from other terminals, and includes an input unit that inputs first owner information about the owner of the terminal and second owner information about the owner of the other terminal, and display information including at least one of information about payment and information about the certificate, and a control unit that, when it is determined based on the first owner information and the second owner information that the owner of the terminal and the owner of the other terminal match, transmits the display information and permission information to permit the display of the display information to the other terminal.

[0008] In one aspect of the present invention, when it is determined that the owner of a terminal matches the owner of another terminal, the device can display display information including at least one of payment information and certificate information on the other terminal. This configuration can prevent the display information from being displayed on other terminals owned by users other than the terminal owner. This can prevent, for example, the display information of the terminal owner from being displayed on terminals owned by users other than the terminal owner. Furthermore, it can prevent, for example, the display information of a user authenticated on a terminal from being displayed on other terminals owned by users different from the terminal. As a result, security can be maintained regarding the display of at least one of payment information and certificate information. [Effects of the Invention]

[0009] According to the present invention, security can be maintained regarding the display of at least one of information related to payment and information related to certificates. [Brief explanation of the drawings]

[0011] 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.

[0012] 1 is a diagram for explaining an overview of processing according to an embodiment. The information processing system 100 includes a display system 1, a main server 2, and a payment terminal 3. The display system 1 includes a first terminal 10 (terminal) and a second terminal 20 (another terminal). The first terminal 10 is a terminal configured to be able to input and output information to and from the second terminal 20. In the embodiment, if the first terminal 10 determines that the owner of the first terminal 10 and the owner of the second terminal 20 match, the second terminal 20 becomes able to display display information.

[0013] 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).

[0014] The second terminal 20 is a small terminal owned by the user. FIGS. 2(a), (b), and (c) are diagrams showing examples of the second terminal 20. In the example shown in FIG. 2(a), the second terminal 20 is a badge-type display terminal. A plurality of second terminals 20 are attached to a bag B. In the example shown in FIG. 2(b), the second terminal 20 is a keychain-type display terminal. In the example shown in FIG. 2(c), the second terminal 20 is a card-type display terminal placed inside a smartphone case.

[0015] For example, the second terminal 20 is a keychain-type display terminal. The second terminal 20 includes a small battery or cell. The second terminal 20 is, for example, a terminal without a SIM card and has only a short-range communication function such as Bluetooth. FIGS. 3(a) and 3(b) are diagrams illustrating usage examples of the second terminal 20. In the example illustrated in FIG. 3(a), the second terminal 20 is a keychain-type terminal attached to the backpack of a user A1 who is out and about. In the example illustrated in FIG. 3(b), the second terminal 20 is a keychain-type terminal attached to the clothing of a user A2 who is running. The second terminal 20 displays display information in a display area D. The display area D is configured, for example, with electronic paper capable of displaying full-color images. Therefore, power consumption is almost zero except when switching image display. By displaying display information on such a second terminal 20, the user can easily present the display information without removing the first terminal 10. Furthermore, the second terminal 20 can display display information regardless of whether the first terminal 10 can communicate with a network.

[0016] The display information is information that includes at least one of information related to payment and information related to a certificate. For example, the display information includes at least one of information related to payment by the owner of the first terminal 10 and information related to the certificate of the owner of the first terminal 10. Also, for example, the display information includes at least one of information related to payment by a user authenticated at the first terminal 10 and information related to the certificate of the owner of the first terminal 10.

[0017] The payment information is information that the user uses for payment. For example, the payment information may be a QR code (registered trademark) used for payment, or a barcode used for payment. The payment information may also include an expiration date, the number of times payment can be made, and the amount that can be paid. This prevents users other than the owner of the payment information from fraudulently using the payment information. The payment information may also include information indicating multiple QR codes. For example, the second terminal 20 can switch between displaying information indicating multiple QR codes. Furthermore, the second terminal 20 can display an image that the user has previously set when no payment is being made.

[0018] The display information may include information about an image representing an NFT (Non-Fungible Token). The information about the image representing an NFT is information about the image content of the NFT. The information about the image representing an NFT may be an image file representing an NFT, a video file representing an NFT, or information representing an NFT image file. The information representing an NFT image file may be any information for identifying the file, and may be, for example, a file name or a file identification number.

[0019] The certificate-related information is information indicating a certificate held by the user. For example, the certificate-related information may be a personal certificate (e.g., a My Number card, a driver's license, or a health insurance card) or a membership card. Note that the first terminal 10 may add a mark or the like to an image indicating the certificate in the certificate-related information. For example, a My Number card or the like read by the first terminal 10 may be added with a special mark or the like within the first terminal 10 to display an image indicating the My Number card or the like.

[0020] The main server 2 is communicatively connected to the first terminal 10 and the payment terminal 3 of the display system 1. The main server 2 stores information related to user payments. The payment terminal 3 is configured to be able to read information related to payments displayed on the second terminal 20 of the display system 1. For example, the payment terminal 3 is used for selling goods at a store or a live music venue.

[0021] In the example shown in FIG. 1, the information processing system 100 is a payment system. The display information is a QR code used for payment. First, in the display system 1, display information such as a QR code for payment and an image showing an NFT is transferred from the first terminal 10 to the second terminal 20. In the information processing system 100, the QR code displayed by the display system 1 is read by the code reader R of the payment terminal 3. The payment terminal 3 transmits the result of reading the QR code and the payment result to the main server 2. The main server 2 coordinates the payment result with the first terminal 10.

[0022] In the example shown in FIG. 3(a), by enabling payments using the second terminal 20 in a location away from the first terminal 10, for example, a child user A1 receives pocket money in advance as electronic money from a parent who owns the first terminal 10. By carrying the second terminal 20, user A1 can use the pocket money to shop in a location away from the first terminal 10 (for example, on the way to school). In the example shown in FIG. 3(b), user A2 goes running without carrying the first terminal 10, but only the second terminal 20. This allows user A2 to easily purchase drinking water and the like while running without carrying a terminal that gets in the way.

[0023] Next, the process for displaying the display information will be described in detail with reference to Fig. 4. Fig. 4 is a block diagram showing the functional configuration of the first terminal 10 and the second terminal 20 according to the embodiment. The first terminal 10 has an input unit 11 and a control unit 12.

[0024] The input unit 11 inputs first owner information about the owner of the first terminal 10 and second owner information about the owner of the second terminal 20, and display information including at least one of payment-related information and certificate-related information. Specifically, in the first terminal 10, the first owner information about the owner of the first terminal 10 is set in advance and stored in a storage unit. The input unit 11 acquires the first owner information from a storage unit (not shown) and inputs the first owner information to the control unit 12. In the second terminal 20, second owner information about the owner of the second terminal 20 is set in advance and stored in a storage unit. The input unit 11 receives the second owner information from the second terminal 20 and inputs the second owner information to the control unit 12.

[0025] When the second terminal 20 is connected to and communicates with another terminal (for example, the first terminal 10), information about the owner of the other terminal may be set as the second owner information. When an image showing an NFT is displayed on the second terminal 20, information about the owner of the NFT may be set as the second owner information. That is, the second owner information may be information about the owner of the NFT displayed on the second terminal 20. When information related to payment is displayed on the second terminal 20, information about the contractor corresponding to the information related to payment may be set as the second owner information. That is, the second owner information may be information about the contractor corresponding to the information related to payment displayed on the second terminal 20.

[0026] If the control unit 12 determines, based on the first owner information and the second owner information, that the owner of the first terminal 10 and the owner of the second terminal 20 match, it transmits display information and permission information for permitting the display of the display information to the second terminal 20. Note that, if the second owner information is information about the owner of the NFT displayed on the second terminal 20, the control unit 12 may transmit the display information and permission information to the second terminal 20 if it determines, based on the first owner information and the second owner information, that the owner of the first terminal 10 and the owner of the NFT match.

[0027] The permission information is information for permitting the display of the display information. Specifically, the permission information may be any information that enables the display of the display information. For example, the permission information may be a token indicating permission to display the display information. The permission information may be assertion information indicating whether the display information can be displayed, or may be key information used to display the display information. As an example, if an image file of the display information 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.

[0028] The permission information includes information indicating an expiration date. If the expiration date has passed, the display information cannot be displayed based on the permission information. For example, if the second terminal 20 cannot periodically obtain the permission information, the display information cannot be displayed. Note that when the second terminal 20 starts displaying the display information 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 display of the display information to continue on the second terminal 20. Furthermore, the control unit 12 may enable the second terminal 20 to display the display information when the expiration date of the permission information has not passed. For example, when the expiration date of the permission information has not passed, the user may press a button P on the second terminal 20 to switch the display on the second terminal 20 from a predetermined image to a display image.

[0029] The control unit 12 may transmit the display information and the permission information to the second terminal 20 based on the distance information. Specifically, the control unit 12 may transmit the display information and the permission information to the second terminal 20 when it further determines that the distance between the first terminal 10 and the second terminal 20 is equal to or less than a threshold. For example, the control unit 12 may transmit the display information and the permission information to the second terminal 20 when it 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 threshold may be set in advance by the owner of the first terminal 10, etc.

[0030] Control unit 12 may stop displaying the display information on second terminal 20 based on the distance information. Specifically, control unit 12 may stop displaying the display information on second terminal 20 when it determines that the distance between first terminal 10 and second terminal 20 exceeds a threshold. For example, control unit 12 may stop displaying the display information on second terminal 20 when it determines that the time from when input unit 11 transmits a beacon to second terminal 20 to when it receives a response from second terminal 20 exceeds a threshold.

[0031] 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 an image indicating an 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. When stopping the display of the display information on the second terminal 20, the control unit 12 stops sending permission information to the second terminal 20, or sends stop information to the second terminal 20 to stop the display of the display information.

[0032] Next, each functional unit of the second terminal 20 will be described. The transmission unit 21 acquires second owner information from a storage unit (not shown). The transmission unit 21 transmits the second owner information to the first terminal 10. The transmission unit 21 transmits a response to the beacon transmitted from the first terminal 10 to the first terminal 10. The reception unit 22 receives display information and permission information from the first terminal 10. The reception unit 22 outputs the received information to the display unit 23. The display unit 23 displays the display information based on the permission information. When the user deletes information related to the owner of the second terminal 20, the user inputs a password set in advance.

[0033] When displaying an image indicating an NFT, the display unit 23 may stop displaying the image indicating the NFT and then start displaying the display information. For example, when the user presses button P (see FIG. 1) on the second terminal 20, the display unit 23 stops displaying the image indicating the NFT and starts displaying the display information. The display unit 23 may also control the display of the display information according to the expiration date of the display information. For example, when the expiration date of the information regarding payment has expired, the display unit 23 may stop displaying the information regarding payment.

[0034] Next, a process for displaying the display information will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of a process for displaying the display information on the second terminal 20.

[0035] First, the first terminal 10 inputs first owner information about the owner of the first terminal 10, second owner information about the owner of the second terminal 20, and display information including at least one of payment-related information and certificate-related information (step S101: input step). Next, the first terminal 10 inputs distance information about the distance between the first terminal and the second terminal (step S102: input step). Finally, if the first terminal 10 determines, based on the first owner information and the second owner information, that the owner of the first terminal 10 and the owner of the second terminal 20 match, it transmits the display information and permission information for permitting the display of the display information to the second terminal 20 (step S103). Then, in step S103, when the second terminal 20 receives the display information and the permission information, it displays the display information based on the permission information.

[0036] Next, the processing in step S103 will be described in detail with reference to Fig. 6. In step S103, if the owner of the first terminal 10 and the owner of the second terminal 20 match, and the second terminal 20 has received and retained the permission information, the first terminal 10 transmits display information (for example, a payment QR code, NFT data) to the second terminal 20.

[0037] First, the first terminal 10 determines whether the first terminal 10 and the second terminal 20 are able to communicate with each other (step S131). In step S131, the first terminal 10 determines whether communication has been established between the first terminal 10 and the second terminal 20 using Bluetooth or the like. For example, the first terminal 10 determines whether the first terminal 10 and the second terminal 20 are paired with each other.

[0038] Next, if the first terminal 10 determines that the first terminal 10 and the second terminal 20 are able to communicate with each other (step S131: YES), the first terminal 10 determines whether or not second owner information is set in the second terminal 20 (step S132). If the first terminal 10 determines that the second owner information is set in the second terminal 20 (step S132: YES), the first terminal 10 determines whether or not the owner of the first terminal 10 and the owner of the second terminal 20 match (step S133).

[0039] When the first terminal 10 determines that the second owner information has not been set in the second terminal 20 (step S132: NO), for example, when the second terminal 20 is a newly purchased terminal and the second owner information has not been set, the first terminal 10 writes the first owner information as the second owner information in the second terminal 20 (step S134). In this way, when the first terminal 10 confirms that the second terminal 20 is an unused product and no owner has been set, it newly registers the first owner information in the second terminal 20.

[0040] Next, if the first terminal 10 determines that the owner of the first terminal 10 and the owner of the second terminal 20 match (step S133: 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 S135). 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 S135: YES), the first terminal 10 determines whether the permission information of the first terminal 10 and the permission information of the second terminal 20 match (step S136). If the first terminal 10 determines that the permission information of the first terminal 10 and the permission information of the second terminal 20 match (step S136: YES), the first terminal 10 proceeds to step S138. Note that the processing of step 135 does not have to be executed, and the first terminal 10 may proceed to step S136 if it determines that the owner of the first terminal 10 and the owner of the second terminal 20 match (step S133: YES).

[0041] When the first terminal 10 writes the first owner information to the second terminal 20 as the second owner information (step S134), or when it determines that the permission information of the first terminal 10 and the permission information of the second terminal 20 do not match (step S136: YES), the first terminal 10 transmits the permission information of the first terminal 10 to the second terminal 20 (step S137) and proceeds to step S138.

[0042] Next, the first terminal 10 transmits the display information to the second terminal 20 (step S138). The second terminal 20 displays the display information (step S139) and ends the process. Furthermore, the first terminal 10 ends the process when it determines that the first terminal 10 and the second terminal 20 are not able to communicate with each other (step S131: NO), when it determines that the owner of the first terminal 10 does not match the owner of the second terminal 20 (step S133: NO), or when it determines that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold (step S135: NO).

[0043] The processes of steps S132 to S137 above are executed by a dedicated application installed in the first terminal 10, for example.

[0044] Fig. 7 is a flowchart showing the processing after the display information is displayed. After the display information is displayed, the processing shown in Fig. 7 is repeatedly executed at a predetermined cycle. For example, a dedicated app or the like installed on the first terminal 10 periodically checks whether the owner information of the first terminal 10 matches the owner information of the second terminal 20.

[0045] 7, the first terminal 10 determines whether the owner of the first terminal 10 and the owner of the second terminal 20 match (step S201). In step S201, 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 saved on the second terminal 20. The above determination process is executed by the dedicated app or the like installed on the first terminal 10.

[0046] When the first terminal 10 determines that the owner of the first terminal 10 and the owner of the second terminal 20 match (step S201: 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 S202). When 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 S202: YES), the first terminal 10 determines whether the first terminal 10 and the second terminal 20 are capable of communicating with each other (step S203). When the first terminal 10 determines that the first terminal 10 and the second terminal 20 are capable of communicating with each other (step S203: YES), the first terminal 10 transmits permission information to the second terminal 20 (step S204). Note that step S202 does not have to be executed, and the first terminal 10 may proceed to step S203 when it determines that the owner of the first terminal 10 and the owner of the second terminal 20 match (step S201: YES).

[0047] If the first terminal 10 determines that the owner of the first terminal 10 does not match the owner of the second terminal 20 (step S201: NO), if it determines that the first terminal 10 and the second terminal 20 cannot communicate with each other (step S202: NO), or if it determines that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold value (step S203: NO), it stops displaying the display information (step S204).

[0048] When the first terminal 10 transmits the permission information to the second terminal 20 (step S203) or stops displaying the display information (step S204), the first terminal 10 ends the process.

[0049] Therefore, when the display of display information based on the permission information starts on the second terminal 20, the first terminal 10 transmits the next permission information to the second terminal 20 within a predetermined period (within the expiration date).

[0050] Next, the effects of the first terminal 10 according to this embodiment will be described. With the first terminal 10 and method according to this embodiment, when it is determined that the owner of the first terminal 10 and the owner of the second terminal 20 are the same, display information including at least one of payment-related information and certificate-related information can be displayed on the second terminal 20. This configuration can prevent the display information from being displayed on the second terminal 20 owned by a user other than the owner of the first terminal 10. This can prevent, for example, the display information of the owner of the first terminal 10 from being displayed on a terminal owned by a user other than the owner of the first terminal 10. Furthermore, it can prevent, for example, the display information of a user authenticated on the first terminal 10 from being displayed on a second terminal 20 owned by a user different from the first terminal 10. From the above, it is possible to maintain security regarding the display of at least one of payment-related information and certificate-related information. Furthermore, it is possible to present the display information to another person without removing the first terminal 10. This allows the user to more easily present payment information or information related to the user's certificate.

[0051] The display information may include at least one of information related to payment by the owner of first terminal 10 and information related to the certificate of the owner of first terminal 10. In this case, it is possible to prevent the display information of the owner of first terminal 10 from being displayed on terminals of users other than the owner of first terminal 10. As a result, it is possible to maintain security regarding the display of information related to payment by the owner of first terminal 10 and information related to the certificate of the owner of first terminal 10.

[0052] The display information may include at least one of information related to payment of a user authenticated at the first terminal 10 and information related to a certificate of the owner of the user's first terminal 10. In this case, it is possible to prevent the display information of a user authenticated at the first terminal 10 from being displayed at the second terminal 20, which has an owner different from that of the first terminal 10. From the above, it is possible to more reliably maintain security regarding the display of at least one of information related to payment and information related to the certificate.

[0053] The second owner information may be information about the owner of the NFT displayed on the second terminal 20, and the control unit 12 may transmit display information and permission information to the second terminal 20 when it determines, based on the first owner information and the second owner information, that the owner of the first terminal 10 and the owner of the NFT match. In this case, when it is determined that the owner of the NFT displayed on the second terminal 20 matches the owner of the first terminal 10, the display information can be displayed on the second terminal 20. This makes it possible to display the display information when it is possible to display an NFT owned by the owner of the first terminal 10 on the second terminal 20. As a result, security can be more reliably maintained regarding the display of at least one of information related to payment and information related to the certificate.

[0054] The permission information may include information indicating an expiration date of the permission information, and when the second terminal 20 starts displaying the display information 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 the display information on the second terminal 20 by continuing to transmit the permission information to the second terminal 20. The first terminal 10 can stop displaying the display information on the second terminal 20 by stopping transmission of the permission information to the second terminal 20.

[0055] 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 the display information and the 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 first terminal 10 and the owner of the second terminal 20 match and the distance between the first terminal 10 and the second terminal 20 is equal to or less than the threshold, the display information can be displayed on the second terminal 20. This makes it possible to more reliably maintain security regarding the display of at least one of the payment-related information and the certificate-related information.

[0056] In the first terminal 10, the control unit 12 may stop displaying the display information on the second terminal 20 when it is determined based on the distance information that the distance between the first terminal 10 and the second terminal 20 exceeds a threshold. In this case, if the user does not have the second terminal 20, for example, if the second terminal 20 is lost or stolen, the display of the display information on the second terminal 20 can be stopped. As a result, security can be more reliably maintained regarding the display of at least one of the information related to the payment and the information related to the certificate.
