In the present embodiment, the user history information includes location information on which the user verified the current location, the date and time of verification, the digital token provided to the user, and the date and time of the provision. In addition to this, the information may also include a history of digital tokens whose provision conditions have been confirmed by the user using a dedicated application.

<User provided information>
The user-provided information is data provided by the user, and is composite information and user-provided data. The composite information is date, text, or handwritten data freely drawn by the user. The date may not be provided by the user. The text may be input by the user or selected by the user from a text prepared in advance by someone other than the user. The text file format is TXT, RTF (Rich Text Format), etc., and the format is not specified. The file format of the handwritten data is JPEG, PNG, etc., and the format is not specified. The user-provided data is text, photos, and videos provided by the user, and there is no specification of these file formats. In this embodiment, the composite information is stored in association with the digital content provided to the user. In addition to this, a configuration in which composite digital content obtained by combining composite information with digital content provided to the user or its URI is stored. The user-provided data is linked to the digital token provided to the user.

<Database example>
4 to 6 are examples of databases of the digital token providing system in this embodiment. 4 and 5 are examples of databases of digital token information in this embodiment. FIG. 6 is an example of user history information and user provided information in this embodiment.

As shown in FIG. 4, the database 201 stores the name of a specific location, location information of that location, and matching range in association with location information ID. The position information in this embodiment is latitude and longitude, and is stored in decimal notation. In addition to this, it may be stored in sexagesimal notation. Information other than latitude and longitude may be stored as location information, as long as the information can match a specific location with the user's current location. Furthermore, the matching range in this embodiment is stored in order to determine within what radius of the stored latitude and longitude the matching performed is considered to be successful. In addition to this, it is conceivable to store in advance a plurality of combinations of latitude and longitude of three or more points and perform verification within that range.

As shown in FIG. 5, the database 201 links providable digital tokens to specifiable providable token IDs, and stores information such as the name of the digital token to be provided, location information ID, conditions for providing the digital token, and the information provided by the digital token. Stores digital content etc. whose ownership etc. are defined.

As shown in FIG. 5, the database 201 stores location information, the number of acquisition times, and fees as examples of conditions for providing digital tokens. For example, in FIG. 5, the number of times Kenrokuen token 2 has been obtained is "3", which means that it is necessary to check the location information with location information ID 1000 three times. When storing the number of digital token acquisitions that need to be acquired, the number of acquisitions for Kenrokuen Token 2 in Figure 5 is ``Kenrokuen Token 1 3 times.'' It is only necessary to remember whether or not you can obtain Kenrokuen Token 2 if you obtain it. Note that the number of times of acquisition may be the number of visits to a specific location defined by location information data or the like.

As shown in FIG. 5, the database 201 stores the acquisition order in the position information ID. For example, in Figure 5, the location information ID of the Shikoku 88 Places (in order) token "0001→...0088" means that the location information ID is 0001 first, then 0002,..., then 0087. , which means that it is necessary to match the position information with 0088 at the end. If you want to remember the acquisition order of the digital tokens that you need to acquire, use the token ID that can be provided, such as "Temple0001→...→Temple0088", as the acquisition order of Shikoku 88 places (in order) tokens. A possible format is to store them in order.

In this embodiment, the user can arbitrarily choose to acquire digital content. In addition to this, when a user obtains a digital token, digital content linked to the digital token may be automatically provided. In this case, when a user obtains a digital token with the same name, the digital content associated with the digital token may not be provided the second time or later. In addition to these, provision conditions may be set for each digital content, and a user may obtain the content if the provision conditions are met. Furthermore, conditions for providing digital content may be similar to those for digital tokens.

As shown in FIG. 6A, the database 201 associates a user with an identifiable user ID, and stores the location information ID verified by the user and the verification date and time representing the date and time of the verification. In this way, by storing the location information ID and verification date and time in association with the user ID, the server 2 is able to verify the acquisition order, number of times of acquisition, period of possible acquisition, and the like.

As shown in FIG. 6(b), the database 201 records digital tokens acquired by the user (referred to as acquired digital tokens) in association with the user ID. In this embodiment, the user ID includes a contract address, a digital token ID, user-provided data that is data provided by the user, a path of synthetic digital content in which digital content acquired by the user and synthetic information are combined, and the user. The acquisition date and time representing the date and time when the digital token and digital content were acquired are stored. In this way, by storing the path of the composite digital content in association with the user ID, the server 2 can display the composite digital content. In this way, by storing the digital token ID and acquisition date and time in association with the user ID, the server 2 can check the acquisition order, the number of acquisition times, the acquisition period, etc.

<Reception means>
Upon receiving the verification instruction including the user's current location, the reception means 202 transmits it to the determination means 203 . The user's current location can be received via the user terminal 3.

The reception means 202 may accept a verification instruction including information used for data verification. The accepted information is transmitted to the determination means 203. Information used for data verification can be received via the user terminal 3. The information used for data matching may be, for example, a unique character string. The user obtains a unique character string from the two-dimensional code, and the reception means 202 receives it.

<Determination means>
Upon receiving a verification instruction including the user's current location from the receiving device 202, the determining unit 203 determines whether the provision conditions are satisfied using the location information and the current location verification result. If the provision conditions are satisfied, the determining means 203 transmits a notification to that effect to the transmitting means 204. Further, the verification date and time may be stored in the database 201 in association with the user ID. The location information to be verified is stored within a certain range, and if the user's current location is within that range, the verification is considered successful.

The determining means 203 includes a verification history and acquisition order of the user's location information, a verification history and acquisition number of the user's location information, a user's acquisition history and acquisition order of the digital token, and a user's digital token acquisition history, acquisition number, and current It may be determined whether the provision conditions are met using at least one of the verification results of the date and time and the available acquisition period. If the provision conditions are satisfied, the determining means 203 transmits a notification to that effect to the transmitting means 204. Further, the verification date and time may be stored in the database 201 in association with the user ID. The user's location information verification history is the history of location information that the user has verified in the past, and includes the date and time of verification. The collation history of the user's location information is as shown in FIG. 6(a). As a result, the order and number of times the user has collated position information in the past can be obtained. The acquisition history of digital tokens is the history of digital tokens that the user has acquired in the past, and includes the date and time of acquisition. This provides the order and number of digital tokens that the user has acquired in the past.

When the determining means 203 receives a verification instruction including information used for data verification from the reception means 202, it may determine whether the provision conditions are satisfied using the verification result of the information used for data verification. If the provision conditions are satisfied, the determining means 203 transmits a notification to that effect to the transmitting means 204. Further, the verification date and time may be stored in the database 201 in association with the user ID. For example, the determining means 203 may be configured to compare the unique character string received by the receiving means 202 with that stored in the database 201.

<Transmission means>
When the determining means 203 determines that the provision conditions are satisfied, the transmitting means 204 transmits a digital token provision instruction to the blockchain network system. Furthermore, the digital token provided to the user, the date and time of acquisition, etc. may be stored in the database 201 in association with the user ID. The provision instruction includes the user's wallet address, contract address, metadata, etc. The user's wallet address and contract address are stored on the blockchain in association with the token URI. The token URI is a URI for referencing metadata of a digital token, and indicates a storage location of the metadata such as a server or IPFS (InterPlanetary File System). Note that the server may be the server 2. The metadata is the name, description, user-provided data, digital content, composite information, receipt data, certificate data, etc. of the digital token, or a metadata URI that allows them to be viewed. The metadata itself may be stored on the blockchain. When the blockchain stores the processing result based on the provision instruction, it sends back a notification to that effect to the server 2.

When the determining means 203 determines that the provision conditions are satisfied, the transmitting means 204 may transmit a provision instruction including the digital content or a URI that allows viewing the digital content to the blockchain network system. Digital content is an image or a video. The file format of the image is JPEG (Joint Photographic Experts Group), PNG (Portable Network Graphics), GIF (Graphics Interchange Format), etc., and the format is not specified. The video file is MP4, MOV, etc., and there is no specification as to its format.

After synthesizing digital content and synthetic information by a synthesizing means 211, which will be described later, the transmitting means 204 may transmit a provision instruction including the synthesized digital content or a URI that allows viewing the synthesized digital content to the blockchain network system.

The transmitting means 204 may transmit a provision instruction including user-provided data or a URI where the user-provided data can be viewed to the blockchain network system. Furthermore, user-provided data or a URI that allows the user-provided data to be viewed may be stored in the database 201 in association with the digital token provided to the user.

The transmitting means 204 may transmit a provision instruction including receipt data or a URI where the receipt data can be viewed to the blockchain network system. Further, receipt data or a URI that allows the receipt data to be viewed may be stored in the database 201 in association with the digital token provided to the user. A receipt is a general receipt provided when a user makes a payment. The recipient of the receipt may be the name listed in the user's basic information or a name newly received from the user.

The transmitting means 204 may transmit a provision instruction including the certificate data or a URI where the certificate data can be viewed to the blockchain network system. Furthermore, certificate data or a URI that allows viewing of the certificate data may be stored in the database 201 in association with the digital token provided to the user. The certificate proves that the user previously held digital tokens. The certificate data may include information in the user's basic information such as the user's user ID, name, date of acquisition by the user, etc. The certificate data may also include user-provided information.

<Reservation reception method>
The reservation accepting means 205 accepts a reservation for providing digital tokens from a user.

<Current location transmission means>
The current location transmitting means 301 transmits the user's current location acquired via the GPS module 38 to the receiving means 202 . Furthermore, if the provision conditions of the digital token for which the reservation for provision has been accepted by the reservation reception means 205 includes an acquisition possible time, the current location transmission means 301 automatically transmits the user's current location to the reception means 202 at the acquisition possible time. It's okay.

<Data verification information transmission means>
The data matching information transmitting means 302 transmits information used for data matching to the receiving means 202.

<Display processing means>
The display processing means 210 receives requests for display processing of various screens from the user, and returns display processing results. In the present embodiment, the display processing means 210 displays the providable digital token and displays a provision request screen. Also, on the provision request screen, a digital token provision request section is displayed. When the user presses the provision request section, a verification instruction is sent to the reception means 202.

The display processing means 210 displays a user basic information management screen on which user basic information can be edited.

Furthermore, the display processing means 210 displays the digital content and composite information based on the URI of the acquired digital token, etc., and displays a content screen. Further, in this embodiment, a synthesizing means 211, which will be described later, displays synthesized digital content obtained by synthesizing synthesized information and digital content. In addition, when a request for display processing of digital content is directly or indirectly received using a metadata URI, a display processing result of the digital content in which the synthesis information has been synthesized is sent based on the digital content and the synthesis information. But it's okay. Thereby, the user can view the digital content with the combined information on the user terminal 3.

The display processing means 210 displays a plurality of digital tokens that can be provided in a selectable manner on the provision request screen.

The selection accepting means 206 accepts the selection of digital tokens.

The display processing means 210 displays the digital token provision condition selected by the user in the selection reception means 206 on the provision request screen. This allows the user to easily confirm the conditions for providing digital tokens.

The display processing means 210 displays the digital token provision request section on the provision request screen. The display processing means 210 may display the digital token provision request portions by distinguishing them depending on the fulfillment status of the provision condition. The sufficiency of the provision conditions is determined by the determining means 203. For example, if you only want to visit one specific place and check the location information of that place with the user's current location, a digital token provision request section will be displayed, but if you need to visit multiple places and check the user's current location, the digital token provision request section will be displayed. For example, the provision request section is not displayed. In addition to this, it is conceivable that the color of the provision request section differs depending on the number of locations where location information needs to be verified.

<Synthesis information reception means>
The composite information receiving means 209 receives composite information. Furthermore, the composite information can be received either before or after acquiring the digital token. Further, the received composite information may be stored in the database 201.

<Synthesis means>
When the composition information receiving means 209 receives the composition information, the composition means 211 creates composite digital content by combining the digital content and the composition information. The synthesized digital content is linked to the digital token ID. Synthetic digital content is a combination of digital content such as an image or a video with synthetic information such as a date, text, and handwritten data freely drawn by the user. The database 201 may store the synthesized digital content or the URI through which the synthesized digital content can be viewed.

<User-provided data reception means>
The user provided data receiving means 212 receives user provided data from the user. Furthermore, user-provided data can be accepted either before or after acquiring the digital token. User-provided data is linked to a digital token ID. Further, the database 201 may store the received user-provided data or a URI that allows the user-provided data to be viewed.

<Pre-transfer acceptance method>
The pre-transfer acceptance means 213 allows a proxy user to check the current location and location information on someone's behalf to select a transfer destination in advance from among the transfer destination user who wishes to transfer and the digital tokens that can be provided on the provision request screen. Accept digital tokens that users wish to transfer. As a general rule, digital tokens for a specific location cannot be provided unless the current location of the user visiting the location is verified against the location information of that location. As an exception, a proxy user may specify in advance the transfer destination user to whom the transfer is desired and the digital token that can be provided, visit the location where the digital token will be provided on behalf of the transfer destination user, and provide the proxy user's current location and its location information. In the case of verification, a digital token may be provided to the transfer destination user.

<Transfer transmission method>
When the determining means 203 determines that the provision conditions are satisfied, the transfer transmitting means 214 transmits a digital token provision instruction to the blockchain network system. As a provision instruction, the wallet address of the transfer destination user is sent instead of the wallet address of the proxy user. This allows the transfer of digital tokens to be permitted with restrictions.

In addition, before transmitting the digital token provision instruction to the blockchain network system, the combination of the proxy user, the transfer destination user, and the digital tokens desired to be transferred to the transfer destination user is stored in the database 201. At a later date, if the proxy user's transfer instruction for the digital token matches that combination, it is conceivable that the transfer instruction is sent to the blockchain network system.

<Search method>
The search means 215 searches for surrounding location information based on the user's current location and location information representing digital token provision conditions. The surrounding location information is location information of digital tokens that can be provided around the user's current location. This makes it possible to search for digital tokens provided around the user's current location.

The search means 215 may search for surrounding location information based on the user's current location, attributes specified by the user, location information representing digital token provision conditions, and attributes associated with each digital token. The user can specify attributes on the basic user information management screen. This makes it possible to search for digital tokens that are near the user's current location and have attributes specified by the user.

When a user searches for surrounding location information, the search means 215 searches surrounding location information based on the user's current location and user attributes, as well as location information representing digital token provision conditions and user attributes linked to the digital token. You can also search. This makes it possible to search for digital tokens that are located near the user's current location and that are frequently acquired by users with the same user attributes.

<Notification means>
Notification means 216 notifies the user of surrounding location information. The surrounding location information is location information searched by the search means 215. This allows the user to know the location information of digital tokens provided around the current location. Further, the user may be notified of explanatory information. The explanatory information is text, images, videos, etc. for advertisement or explanation of the digital token.

<Payment determination method>
Payment determination means 217 determines whether the payment made by the user is successful or not. Further, it may be determined whether the payment made by the user is sufficient, and if the payment is sufficient, receipt data may be provided. The provided receipt data or a URI that allows viewing of the receipt data may be stored in the database 201 in association with the digital token obtained by making the payment.

The payment determination means 217 may determine whether a payment made by the user is possible. Determining whether or not a payment made by a user is possible means that the balance charged by the user is recorded in the user's basic information, and a digital token or digital content in which a certain charge is stored is acquired within the range of the balance. Determine whether it is possible. Based on this determination, the display processing means 210 may perform display processing by distinguishing the provision requesting sections.

<Certificate provision means>
The certificate providing means 218 provides certificate data indicating that the user holds the digital token. The provided certificate data or a URI that allows the certificate data to be viewed may be stored in the database 201. With this, even if a user provides a digital token that he/she owns to another user, it is possible to prove that the user has held the digital token in the past.

Note that although this embodiment has shown a configuration in which the server 2 is realized by a single computer device, the present invention is not limited to this. For example, the server 2 may be implemented by a plurality of computer devices, such as a configuration in which the determining means 203 is provided in another computer device.

<Processing of digital token provision>
FIG. 7 is a flowchart showing the flow of processing for providing digital tokens in this embodiment. In step S11, the accepting means 202 accepts a user's selection of a digital token that can be provided from a dedicated application downloaded to the user terminal 3.

In step S12, the display processing means 210 displays the conditions for providing the digital token selected in step S11. Furthermore, in step S12, the display processing means 210 displays a digital token provision request section for transmitting a verification instruction including the user's current location. Furthermore, upon receiving the user's selection of a digital token, the determining means 203 determines whether the provision conditions for the digital token selected by the user are satisfied, and based on the result, the display processing means 210 determines whether the provision conditions are satisfied or not. The digital token provision request part may be displayed and processed separately.

In step S13, when the user presses the provision request section displayed on the screen of the dedicated application, a verification instruction including the user's current location is transmitted to the server 2. Note that an embodiment may also be considered in which a verification instruction including the user's current location is transmitted to the server 2 by selecting the digital token in step S11.

Furthermore, the verification instruction may include information used for data verification. For example, when a digital token is selected in step S11, a button for starting a camera may be displayed on a dedicated application together with conditions for providing the digital token. By pressing a button to activate the camera and reading a two-dimensional code, the user's current location and information used for data verification are transmitted. In addition to this, it is also conceivable that the user's current location and information used for data verification are transmitted by pressing a button that activates a camera displayed on a dedicated application and reading a two-dimensional code. In addition, the user terminal 3 transmits the user's current location, after verification by the server, the server transmits an instruction to read the two-dimensional code to the user terminal 3, and the user terminal 3 performs verification including information used for data verification. A possible method is to send an instruction.

Furthermore, when a digital token is selected in step S11, an instruction to request a short-range wireless communication connection is displayed on the user terminal 3, and when the connection is established, the user's current location and information acquired through the short-range wireless communication connection are transmitted. There are several possible forms in which this is done. Furthermore, when a dedicated application is started and a short-range wireless communication connection is established, the user's current location and information acquired through the short-range wireless communication connection may be transmitted. In addition, the user's current location is transmitted from the user terminal 3, and after verification by the server, the server transmits an instruction to connect the short-range wireless communication to the user terminal 3, and the user terminal 3 transmits the user's current location to the user terminal 3. A possible form is to transmit a verification instruction that includes the information to be acquired.

Furthermore, in step S13, in addition to transmitting the verification instruction, the user may also transmit at least one of user-provided data and composite information. In addition, after acquiring the digital token and digital content, at least one of user-provided data and composite information may be transmitted.

In step S14, location information, the user's current location, etc. are verified. In addition to location information and the user's current location, verification may include acquisition order, number of times of acquisition, acquisition period, acquisition time, information used for data verification, success/failure of payment, etc.

In step S15, it is determined whether the conditions for providing the digital token are met. It is determined whether the location information stored as a digital token provision condition and the user's current location are successfully verified. Other sufficiency determinations include acquisition order, number of acquisitions, acquisition period, acquisition time, information used for data verification, and success/failure of payment. If it is determined in step S15 that the provision conditions are satisfied (step S15: Yes), the process proceeds to step S16. If the determination of satisfaction of the provision conditions is negative in step S15 (step S15: No), the process waits for the user to select a digital token again.

In step S16, a digital token provision instruction is sent to the blockchain network system.

<Verification of current location and location information by proxy>
FIG. 8 is a diagram illustrating an example of the processing flow of collating the current location and location information and transferring the digital token on behalf of the user in this embodiment. In S21, the user selects the transfer destination user and the digital token he/she wishes to transfer, and the pre-transfer acceptance means 213 accepts the selection.

In step S22, a digital token provision instruction is sent to the blockchain network system. Unlike step S16, since the user receiving the provision is the transfer destination user, the wallet address is stored in the blockchain.

<If the provision conditions include the available time of acquisition>
FIG. 9 is a diagram illustrating an example of the flow of a process for making a reservation for providing a digital token that includes the obtainable time as a provision condition in this embodiment. In step S31, the user makes a reservation for provision of a digital token that includes the obtainable time as a provision condition. The dedicated application remembers to send the user's current location at the available time.

In step S32, if the user activates the dedicated application before the obtainable time, the dedicated application automatically transmits the user's current location to the receiving means 202 at the obtainable time.

<Notification of surrounding location information>
FIG. 10 is a diagram illustrating an example of the flow of processing for searching, notifying, and displaying surrounding position information in this embodiment. In step S41, the user terminal 3 transmits the user's current location to the server 2.

In step S42, the search means 215 searches for surrounding location information from the received current location and the location information of the digital token stored in the database.

In step S42, the search means 215 may further search for surrounding location information using attributes specified by the user and digital token attributes representing location information associated with the digital token. The attributes specified by the user are likely to be related to what the user is interested in. In other words, by searching surrounding location information including this information, there is a high possibility that the current location can be transmitted and digital tokens of interest to the user can be presented.

In addition, the search means 215 may search for surrounding location information using the user attributes and location information of the user who transmitted the current location. From the user history information, it is possible to know which user attributes a certain providable token is popular among users. Therefore, by searching for surrounding location information using the user attributes and user history information of the user who sent the current location, it is highly possible to present digital tokens that are of interest to the user who sent the current location.

In step S43, the notification means 216 notifies the user of the surrounding location information.

In step S44, the accepting means 202 accepts the user's selection of surrounding position information.

In step S45, the notification means 216 displays an advertisement or explanation of the digital token of the selected surrounding location information.

Note that data transmission and reception, requests, etc. between the server 2 and the user terminal 3, etc. in this embodiment may be performed via a browser application on the user terminal 3, or may be performed via an API. .
