The digital token information is information about the digital token provided to the user, and provision conditions are set for at least a part of the digital token provided to the user. In this embodiment, location information for verifying the user's current location is associated with the digital token as a provision condition of the digital token.

Also, as the conditions for providing the digital token, one or more of the order of acquisition, the number of times of acquisition, and the acquisition period may be associated with the digital token instead of or in addition to the location information. The acquisition order is the order of location information that needs to be collated in order to acquire a digital token or the order of acquisition of digital tokens that need to be acquired. The number of times of acquisition is the number of times of location information that needs to be collated in order to acquire a digital token or the number of times of acquisition of a digital token that needs to be acquired. Acquisition period is the period during which digital tokens can be acquired. A daily unit such as "11:00 to 13:00", a minute unit such as "6:00 to 6:30", and the like are conceivable.

Further, as a provision condition of the digital token, the information used for data collation may be associated with the digital token instead of or in addition to the location information. The information used for data collation is, for example, information acquired via a device capable of reading a two-dimensional code placed at a place where a digital token can be obtained or a short-range wireless communication connection. The two-dimensional code is a QR code (registered trademark), Aztec Code, etc., and there is no specification for its format. The short-range wireless communication includes Bluetooth (registered trademark), NFC (Near Field Communication), etc., and the format thereof is not specified.

Also, as a provision condition of the digital token, an acquirable time may be associated with the digital token instead of or in addition to the location information. Acquirable time is the time at which the digital token can be acquired, and the digital token cannot be acquired unless the current location is transmitted at that time.

Digital token information includes digital content linked to the digital token. Digital content is an image or video for which a digital token becomes ownership, viewing rights, or the like.

Digital token information may include digital token attributes. A digital token attribute is an attribute representing the type, category, etc. of a place associated with the digital token. For example, a digital token for Zojoji would include a digital token attribute of "temple."

Digital token information may include descriptive information. Description information is information about advertisements or descriptions of digital tokens, and may be text, images, or videos.

<User history information>
The user history information is information related to the history of users who use the digital token provision system. In the present embodiment, the user history information is location information with which the user checked the current location, the date and time of the check, the digital token provided to the user, and the date and time of the provision. In addition to this, the user may use a dedicated application to include the history of digital tokens for which provision conditions have been confirmed.

<User-provided information>
The user-provided information is data provided by the user, and includes synthesized information and user-provided data. The synthetic 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 may be selected by the user from text prepared in advance by someone other than the user. The text file format is TXT, RTF (Rich Text Format), etc., and there is no specification for the format. The file format of the handwritten data is JPEG, PNG, etc., and the format is not specified. User-provided data is text, pictures, and moving images provided by the user, and there is no specification for these file formats. In this embodiment, the combined information is stored in association with the digital content provided by the user. In addition to this, it is conceivable that the synthesized digital content obtained by synthesizing the synthesized information with the digital content provided by the user or the URI thereof is stored. User-provided data is tied to a digital token provided to the user.

<Database example>
4 to 6 are examples of the database of the digital token provision system in this embodiment. 4 and 5 are an example of a digital token information database 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 place, the position information of the place, and the matching range in association with the position information ID. The position information in this embodiment is latitude and longitude, and is stored in decimal numbers. Alternatively, it may be stored in hexadecimal notation. Any information other than latitude and longitude may be stored as position information as long as it is information that can match a specific location with the user's current location. Also, the collation range in this embodiment is stored to determine whether collation within a radius of how many meters around the stored latitude and longitude is considered successful. In addition, it is conceivable to store a plurality of combinations of three or more latitudes and longitudes in advance, and perform collation within that range.

As shown in FIG. 5, the database 201 associates a digital token that can be provided with an identifiable token ID that can be provided, and stores the name of the provided digital token, the location information ID, the conditions for providing the digital token, and the digital token. Stores digital content, etc. for which ownership, etc. is defined.

As shown in FIG. 5, the database 201 stores location information, the number of acquisitions, and fees as an example of digital token provision conditions. For example, in FIG. 5, the number of acquisition times of Kenrokuen token 2 “3” means that it is necessary to collate the position information with the position information ID of 1000 three times. When storing the number of acquisitions of digital tokens that must be acquired, the number of acquisitions of Kenrokuen token 2 in FIG. It is only necessary to store whether or not the Kenrokuen token 2 can be acquired if it is acquired. Note that the number of acquisitions 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 FIG. 5, "0001→...0088" of the location information ID of the Shikoku 88 places (ordered) token means that the location information ID is 0001 first, then 0002, . , means that it is necessary to match the location information, which is 0088 at the end. When storing the acquisition order of digital tokens that need to be acquired, as the acquisition order of Shikoku 88 place (sequential) tokens, the available token ID are stored in order.

In this embodiment, the user can optionally choose to acquire digital content. In addition to this, when a user acquires a digital token, it is possible to automatically provide digital content linked to the digital token. In this case, when the user acquires a digital token with the same name, the digital content linked to that digital token does not have to be provided from the second time onward. In addition to these, it is conceivable that a provision condition is set for each digital content, and the user can obtain the content when the provision condition is satisfied. In addition, the 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 verification date and time. In this way, by storing the location information ID and the verification date and time in association with the user ID, the server 2 can verify the order of acquisition, the number of times of acquisition, the acquisition period, and the like.

As shown in FIG. 6B, the database 201 records the digital token acquired by the user (referred to as an acquired digital token) in association with the user ID. In this embodiment, the user ID includes a contract address and a digital token ID, user-provided data that is data provided by the user, the path of the synthesized digital content obtained by synthesizing the digital content and the synthesized information obtained by the user, the user stores the acquisition date and time representing the date and time when the digital token and digital content were acquired. 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. By storing the digital token ID and the date and time of acquisition in association with the user ID in this way, the server 2 can check the order of acquisition, the number of times of acquisition, the acquisition period, and the like.

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

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

<Determination means>
Upon receiving a collation instruction including the user's current location from the reception unit 202, the determination unit 203 determines whether the provision condition is satisfied using the location information and the current location collation result. When the provision condition is satisfied, the determination means 203 transmits that effect to the transmission means 204 . Also, the collation 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 verification is considered successful if the user's current location is within that range.

The determination unit 203 determines the collation history and acquisition order of the user's location information, the collation history and acquisition frequency of the user's location information, the acquisition history and acquisition order of the user's digital token, the acquisition history and acquisition frequency of the user's digital token, and the current Satisfaction of the provision condition may be determined using at least one of the matching result of the date and time and the available period. When the provision condition is satisfied, the determination means 203 transmits that effect to the transmission means 204 . Also, the collation date and time may be stored in the database 201 in association with the user ID. The collation history of the user's location information is the history of location information collated by the user in the past, and includes the date and time of collation. The matching history of the user's position information indicates something like FIG. 6(a). As a result, the order and the number of times the user has collated the position information in the past can be obtained. The digital token acquisition history is the history of digital tokens acquired by the user in the past, and includes the date and time of acquisition. As a result, the order and number of digital tokens acquired by the user in the past can be obtained.

Upon receiving a collation instruction including information used for data collation from the acceptance unit 202, the judging unit 203 may judge sufficiency of the provision condition using the collation result of the information used for data collation. When the provision condition is satisfied, the determination means 203 transmits that effect to the transmission means 204 . Also, the collation date and time may be stored in the database 201 in association with the user ID. The determining means 203 may, for example, collate the unique character string received by the receiving means 202 with what is stored in the database 201 .

<Transmission means>
When the determination means 203 determines that the provision condition is satisfied, the transmission means 204 transmits a digital token provision instruction to the blockchain network system. Further, the database 201 may store the digital token provided to the user, the date and time of acquisition, etc. in association with the user ID. The provision instructions include the user's wallet address, contract address, metadata, and the like. The user's wallet address and contract address are linked to the token URI and stored in the blockchain. A token URI is a URI for referring to metadata of a digital token, and indicates a storage location of metadata such as a server or IPFS (InterPlanetary File System). Note that the server may be the server 2 . Metadata is the name of the digital token, description, user-provided data, digital content, composite information, receipt data, certificate data, etc., or a metadata URI where they can be viewed. The metadata itself may be stored on the blockchain. When the block chain stores the processing result based on the provision instruction, it returns that fact to the server 2 .

When the determination means 203 determines that the provision condition is satisfied, the transmission means 204 may transmit a provision instruction including the digital content or a URI that allows viewing of the digital content to the blockchain network system. Digital content is images or moving images. The image file format is JPEG (Joint Photographic Experts Group), PNG (Portable Network Graphics), GIF (Graphics Interchange Format), etc., and there is no specification for the format. The moving image file is MP4, MOV, etc., and there is no specification for the format.

After synthesizing the digital content and the synthesizing information by 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 of the synthesized digital content to the blockchain network system.

<Data Verification Information Transmission Means>
Data collation information transmission means 302 transmits information used for data collation to reception means 202 .

<Display processing means>
The display processing means 210 receives display processing requests for various screens from the user and returns display processing results. In this embodiment, the display processing means 210 performs display processing on the digital token that can be provided, and displays the provision request screen. Also, on the provision request screen, display processing is performed for the provision request portion of the digital token. When the user presses the provision request section, a collation instruction is transmitted to the receiving means 202 .

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

Also, the display processing means 210 displays the content screen by performing display processing on the digital content and the composite information based on the URI of the acquired digital token. Further, in this embodiment, the synthesizing unit 211, which will be described later, performs display processing of synthesized digital content obtained by synthesizing the synthesis information and the digital content. In addition, when a digital content display processing request is received directly or indirectly using a metadata URI, the display processing result of the digital content synthesized with the synthesis information is transmitted based on the digital content and the synthesis information. But it's okay. Thereby, the user can browse the digital content combined 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.

Selection accepting means 206 accepts selection of a digital token.

The display processing means 210 displays the conditions for providing the digital token selected by the user in the selection receiving means 206 on the provision request screen. This allows the user to easily check the provision conditions of the digital token.

The display processing means 210 displays the provision request portion of the digital token on the provision request screen. The display processing means 210 may perform display processing of the provision request part of the digital token by distinguishing it according to the satisfaction status of the provision condition. The determination means 203 determines whether the provision condition is satisfied. For example, if you just want to visit one specific place and match the location information of that place with the user's current location, the digital token provision request part will be displayed, and if you need to visit multiple places and check For example, the provision request part 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 for which location information needs to be collated.

<Synthetic information receiving means>
Synthesis information receiving means 209 receives synthesis information. In addition, it is possible to receive the combined information either before or after acquiring the digital token. Also, the received synthesis information may be stored in the database 201 .

<Synthesis means>
When the synthesis information receiving means 209 receives the synthesis information, the synthesizing means 211 creates synthesized digital content by synthesizing the digital content and the synthesizing information. The composite digital content is tied to the digital token ID. Synthetic digital content is obtained by synthesizing synthetic information such as date, text, and handwritten data freely drawn by a user on digital content such as an image or moving image. The database 201 may store the synthesized digital content or a URI that allows browsing of the synthesized digital content.

<Means for accepting user-provided data>
User-provided data accepting means 212 accepts user-provided data from a user. Also, user-provided data can be accepted either before or after obtaining a digital token. User-provided data is tied to a digital token ID. Also, the received user-provided data or a URI that allows browsing of the user-provided data may be stored in the database 201 .

<Method of accepting advance transfer>
The pre-transfer acceptance means 213 receives a transfer destination user who wishes to transfer in advance from the proxy user who checks the current location and position information on behalf of someone and the transfer destination from among the digital tokens that can be provided by the proxy user on the provision request screen. Accept digital tokens that you wish to transfer to users. In principle, a digital token for a particular place cannot be provided without matching the current location of the user visiting that place with the location information of that place. As an exception, the proxy user designates in advance a transferee user who wishes to transfer and a digital token that can be provided, visits the place where the digital token is provided on behalf of the transferee user, and obtains the current location of the proxy user and its location information. In the case of verification, the digital token may be provided to the transferee user.

<Transfer Transmission Means>
When the determination means 203 determines that the provision condition is satisfied, the transfer transmission means 214 transmits a digital token provision instruction to the blockchain network system. As the provision instruction, the transferee user's wallet address is sent instead of the proxy user's wallet address. As a result, the transfer of digital tokens can be permitted with restrictions.

In addition, before sending a digital token provision instruction to the blockchain network system, the database 201 stores a combination of the proxy user, the transferee user, and the digital token that the transferee user desires to transfer. At a later date, if the proxy user's transfer instruction for the digital token matches the combination, the transfer instruction may be sent to the blockchain network system.

<Search method>
The search means 215 searches for peripheral position information based on the user's current position and the position information representing the conditions for providing the digital token. The peripheral location information is location information of the digital tokens that can be provided in the vicinity of the user's current location. This allows searching for digital tokens offered around the user's current location.

The search means 215 may search for peripheral location information based on the user's current location, attributes specified by the user, location information representing conditions for providing digital tokens, and attributes associated with each digital token. The user can specify attributes on the user basic information management screen. As a result, it is possible to search for digital tokens that are in the vicinity of the user's current location and have attributes specified by the user.

When a user searches for peripheral location information, the search means 215 retrieves the peripheral location information based on the user's current location, user attributes, location information representing conditions for providing digital tokens, and user attributes linked to digital tokens. You can 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 attribute.

<Notification method>
The notification means 216 notifies the user of the surrounding position information. The peripheral location information is location information retrieved by the retrieval means 215 . This allows the user to know the location information of the digital tokens provided around the current location. Also, the explanation information may be notified to the user. The descriptive information is text, images, videos, or the like for advertisement or description of the digital token.

<Payment determination method>
The payment determination means 217 determines whether the payment made by the user is successful. In addition, it is also possible to determine whether the payment made by the user is satisfactory, and to provide receipt data when the payment is satisfactory. The provided receipt data or the URI at which the receipt data can be browsed may be stored in the database 201 in association with the digital token acquired by making the payment.

The settlement determination means 217 may determine whether or not settlement by the user is possible. Determining whether or not settlement by the user is possible means that the user's basic information records the balance charged by the user, etc., and a digital token or digital content that stores a certain fee is acquired within 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 part.

<Certificate provision method>
Certificate providing means 218 provides certificate data indicating that the user possesses the digital token. The database 201 may store the provided certificate data or a URI that allows browsing of the certificate data. As a result, even when a user provides another user with a digital token owned by the user, it is possible to prove that the user owned the digital token in the past.

In addition, in this embodiment, although the structure which implement|achieves the server 2 by the single computer apparatus was shown, this invention is not limited to this. For example, a configuration in which the determination means 203 is provided in another computer device, or a configuration in which the server 2 is realized by a plurality of computer devices may be employed.

<Processing of provision of digital tokens>
FIG. 7 is a flow chart showing the flow of processing for providing a digital token in this embodiment. In step S<b>11 , the accepting unit 202 accepts selection of a digital token that can be provided by the user from the 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. Further, 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, when receiving the selection of the digital token by the user, the determination means 203 determines whether the provision condition of the digital token selected by the user is satisfied, and based on the result, the display processing means 210 The digital token provision request part may be displayed separately.

In step S<b>13 , when the user presses the provision request section displayed on the dedicated application screen, a verification instruction including the user's current location is transmitted to the server 2 . An embodiment is also conceivable in which a verification instruction including the user's current location is sent to the server 2 by selecting a digital token in step S11.

Furthermore, information used for data collation may be included in the collation instruction. For example, when a digital token is selected in step S11, a mode is conceivable in which a dedicated application displays conditions for providing the digital token and a button for activating the camera. By pressing the button to activate the camera and reading the two-dimensional code, the user's current location and information used for data verification are transmitted. In addition to this, by pressing a camera activation button displayed in a dedicated application and reading a two-dimensional code, the user's current location and information used for data collation 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 read the two-dimensional code to the user terminal 3, and verification including information used for data verification from the user terminal 3 A form of sending an instruction is conceivable.

Also, when a digital token is selected in step S11, an instruction requesting connection of short-range wireless communication is displayed on the user terminal 3, and when the connection is made, the user's current location and information obtained by connecting the short-range wireless communication are transmitted. can be considered. Also, when a dedicated application is activated and a short-range wireless communication connection is established, the user's current location and information acquired by 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 connects to the short-range wireless communication. A form of transmitting a verification instruction including the information to be acquired is conceivable.

Further, in step S13, the user may transmit at least one of the user-provided data and the synthesized information while transmitting the verification instruction. Alternatively, at least one of user-provided data and synthetic information may be transmitted after obtaining a digital token and digital content.

In step S14, the position information and the user's current location are collated. As collation other than the position information and the user's current location, the order of acquisition, the number of times of acquisition, the acquisition possible period, the acquisition possible time, the information used for data collation, the success or failure of payment, and the like may be collated.

In step S15, it is determined whether the conditions for providing the digital token are satisfied. It determines whether the location information stored as the condition for providing the digital token and the user's current location have been successfully compared. As other determinations of sufficiency, the order of acquisition, number of times of acquisition, available period, available time of acquisition, information used for data collation, success or failure of payment, etc. are also determined. When the determination of the satisfaction of the provision conditions is affirmative in step S15 (step S15: Yes), the process proceeds to step S16. If it is determined in step S15 that the provision condition is satisfied is negative (step S15: No), it waits for the user to select the 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 showing an example of the processing flow of collation of current location and location information and transfer of a digital token on behalf of a user in this embodiment. In S21, the user selects the transfer destination user and the digital token to be transferred, and the advance transfer acceptance means 213 accepts it.

In step S22, a digital token provision instruction is sent to the blockchain network system. Unlike step S16, the user who receives the provision is the transferee user, so the wallet address is stored in the blockchain.

<When the available time is included in the provision conditions>
FIG. 9 is a diagram showing an example of the flow of processing for making a reservation for provision of a digital token that includes an acquirable time as a provision condition in this embodiment. In step S31, the user makes a reservation for provision of a digital token that includes an acquirable time as a provision condition. A dedicated application remembers to send the user's current location at that available time.

In step S32, when the user activates the dedicated application before the obtainable time, the dedicated application automatically transmits the user's current location to the reception unit 202 at the obtainable time.

<Notification of surrounding location information>
FIG. 10 is a diagram showing an example of the flow of processing for searching, notifying, and displaying peripheral position information in this embodiment. In step S<b>41 , the user terminal 3 transmits the user's current location to the server 2 .

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

In step S42, the search means 215 may further search for peripheral 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 relevant to what the user is interested in. In other words, there is a high possibility that the present location can be transmitted and the digital token of interest to the user can be presented by searching the surrounding location information including it.

Alternatively, the search means 215 may search for peripheral position information using the user attributes and position information of the user who sent the current position. From the user history information, it is possible to find out what kind of user attribute a certain providable token is popular among users. Therefore, by searching the surrounding location information using the user attributes and user history information of the user who sent the current location, there is a high possibility that the digital token of interest to the user who sent the current location can be presented.

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

In step S44, the accepting unit 202 accepts selection of surrounding position information by the user.

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

Data transmission/reception and requests between the server 2 and the user terminal 3 or the like in the present embodiment may be performed via a browser application on the user terminal 3 or may be performed via an API. .
