Description

Event proving system

[ technical field ]

The present invention relates to a technique for proving by using an NFT (Non-homogeneous Token), and more particularly, to an effective technique suitable for an event proving system for proving events, behaviors, facts, and the like.

[ background Art ]

The utilization of NFT (Non-heterogeneous Token) technology, which is a technology for implementing unique and Non-replaceable data units on blockchains, is rapidly expanding. The use of NFTs to be able to claim, prove, identify unique rights in the digital space, etc., and the inability of the ownership of the NFT to replicate and tamper with, as a basis, to be able to send and transfer and track the value itself, is thus being investigated by various mechanisms that exploit and exploit such characteristics.

For example, japanese patent No. 7033352 (patent document 1) describes an art work trading system including: an artwork transaction management device, by which registered users, namely artists, register the exhibition of the artwork requested by the exhibition; and an ownership token management device that issues ownership tokens (NFTs) corresponding to the post-exhibition registered works of art and that exhibits the issued ownership tokens on a blockchain network.

Further, for example, japanese patent application laid-open No. 2022-35296 (patent document 2) describes a reservation system in which a server to which a smart contract has been installed on a blockchain platform issues and transfers a 1 st token indicating a reserved parking spot, issues and transfers a 2 nd token indicating a reserved car pool to a vehicle having the parking spot as a destination, and performs a verification of the 2 nd token when the car pool is used, and verifies the 1 st token when the parking spot is used.

Further, for example, japanese patent No. 7093487 (patent document 3) describes a mechanism that manages product-related information and requests NFT distribution including product purchaser information and a product serial number, and in this way, a reliable correspondence relationship is established between a genuine owner of a product and the product, so that management can be performed throughout the life cycle from purchase to discard of the product.

Summary of the invention

[ problem to be solved by the invention ]

According to the prior art described above, NFT can be utilized to prove the existence and content of any rights and value of an item (including digital content), usage rights, etc., and transfer or track it. In this case, for example, regarding drawing, the current attribution of rights such as ownership and usage rights, and history transfer history can be verified by the NFT associated with the drawing.

On the other hand, for example, if there is an NFT associated with the drawing, the fact that the drawing was once held by the owner after transferring the drawing may be kept in the NFT as a history, but in a state where the person does not hold the NFT, it is difficult for the person to autonomously prove the fact, and many times there is no NFT associated with the object article or the like in real life. That is, there is a need for a means of proving to a third party an event, behavior, fact, etc. that is independent of the movement of the item or value, but not the ownership of the drawing, but the fact that the drawing was once held, of the individual information itself.

Accordingly, an object of the present invention is to provide an event certification system for certifying an event, a behavior, a fact, or the like (hereinafter, collectively referred to as "event") for which individual information itself is not valuable, independently of the movement of an article or value, to a third party.

These and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[ means for solving the problems ]

In the invention disclosed in the present application, a representative summary is briefly described below.

An event certification system according to an exemplary embodiment of the present invention presents certification information for certifying the presence of a user-related event, and includes: a UI processing unit that provides a user terminal used by the user with a user interface related to the user performing an action such as purchasing a commodity related to an event that may be a certification target; a settlement processing unit that performs settlement processing related to an event that may be a certification target, and the like; a certification processing unit configured to determine whether or not a related event such as settlement processed by the settlement processing unit belongs to a certification target, and to collect related certification information of the event, the related event belonging to the certification target; and a wallet managing section that gives the certification information to attribute information, and issues NFT to a wallet related to the user on a blockchain.

[ Effect of the invention ]

In the invention disclosed in the present application, the effects obtained by the representative contents are briefly described below.

That is, according to representative embodiments of the present invention, it is possible to prove to a third party that individual information itself is not valuable, independent of the arrival or arrival of an item or value.

[ description of the drawings ]

Fig. 1 is a schematic diagram schematically showing an example of the structure of an event certification system according to an embodiment of the present invention.

Fig. 2 is a flowchart schematically showing an example of the event certification processing flow in the embodiment of the present invention.

Detailed description of the preferred embodiments

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In all the drawings describing the embodiments, the same reference numerals are given to the same parts in principle, and the repetitive description thereof will be omitted. On the other hand, in some cases, the same reference numerals are given to the portions where the reference numerals are given to the portions in some drawings, and the portions are not shown again in the descriptions of other drawings.

< overview >

The event certification system according to an embodiment of the present invention can certify an event that is not valuable by itself (for example, not ownership of a drawing but a fact that the drawing was held), to a third party, independently of the arrival and arrival of an item or value, by NFT-ing the related information of the event.

Thus, by presenting the NFT to a third party, for example, in the case of the drawing, the owner can prove the fact that he has purchased and held the drawing, and further prove the fact that he has supported the drawing and the painter, after transferring the drawing. Further, as other specific examples, for example, a purchased horse ticket wins, is converted into a prize, and can be certified as a supporter of the winning horse itself, or can be certified as a donation fact after making some donations. In addition, it can prove that itself is a duplicate purchaser of a particular manufacturer, and the manufacturer can lock customers and the like when providing a particular service to a premium customer. Further, for example, in real estate sales and the like where there may be a time lag between payment of a sales payment to actual delivery of an item, the payment of the sales payment may be used to prove the payment of the sales payment for eliminating an illegal act.

As can be seen from these examples, each example relates to an event that can be authenticated and includes a settlement behavior such as a payment of a user, and by capturing the settlement behavior and issuing an NFT in the form of authentication information including a settlement object, an associated remark such as the content of the event, and the like, the event can be identified and authenticated.

System constitution >

Fig. 1 is a diagram schematically showing an example of the configuration of an event certification system according to an embodiment of the present invention. The event certification system 1 is configured by, for example, a server device, a virtual server set up on a cloud computing service, a PC, or the like, and executes middleware such as OS (Operating System) or DBMS (DataBase Management System) or a Web server program developed from a recording device such as HDD (Hard Disk Drive) or SSD (Solid State Drive) on a memory, or software running thereon by using a not-shown CPU (Central Processing Unit) to realize various functions related to certifying an event of the user 2.

The event certification system 1 includes, for example, a User Interface (UI) processing unit 11, a settlement processing unit 12, a certification processing unit 13, a wallet managing unit 14, and the like, which are installed as software. Although the example of fig. 1 shows the form in which these components are mounted on one server system, these components are logically expressed, and in practice, some or all of these components may be mounted as separate servers, systems, services, etc. and connected via a network not shown.

The UI processing unit 11 has a function of providing the user terminal 21 such as a smart phone or a PC held by the user 2 with a relevant user interface for the user 2 to perform payment and settlement of the purchased goods, services, rights, donations, or the like related to the event that may be the certification target. For example, a screen for performing various operations such as selecting and settling of commodities by the user 2 may be provided via a dedicated application program, not shown, installed on the user terminal 21 or a Web browser. Since the process of selecting and purchasing commodities and the like is the same as that of the conventional EC website and the like, the details thereof will not be described in detail, and the system may be installed alone in the event verification system 1 or may be connected to an external EC website and the like. Further, as described later, a screen for accessing the wallet 41 managing the NFT of the user 2 to perform a query and an operation may be provided.

The settlement processing unit 12 has a function of performing settlement-related processing such as payment of a deposit or donation related to an event that may be a certification target. For example, an interface for providing instructions or requests for settlement to acquire and query processing results functions as a settlement system or a settlement service connected to the external financial institution 3 or the like via a network not shown. The settlement means is not limited to the means by the financial institution 3 such as cash transfer and remittance, credit card, etc., but any means such as various kinds of point service, virtual money (encrypted asset) on the blockchain 4, etc. may be used.

The certification processing unit 13 has a function of determining whether or not the settlement-related event belongs to a certification target based on the condition registered in the NFT issuing condition 15 when the settlement performed by the settlement processing unit 12 is completed, and acquiring and collecting information for certification belonging to the certification target. The NFT issuance condition 15 may be set and registered in advance by, for example, the user 2, a seller such as a commodity, or a manager of the event certification system 1, or may be designated by the user 2 each time the settlement of the object is performed.

A condition for determining whether or not the settlement-related event belongs to a certification target, that is, whether or not the settlement-related event belongs to the NFT issuance target is registered in the NFT issuance condition 15. Various values such as attribute information (ID information, category, etc.) of purchased goods, attribute information (ID information, age, sex, registration plan, whether or not it belongs to the user of Web3, etc.), attribute information (ID information, industry, registration plan, etc.) of a seller of goods, information about purchase and settlement contents (settlement time, settlement means, settlement amount, number of purchases of goods and services, number of purchases from the same seller, etc.) can be set in this condition.

The information for certifying the event may be, for example, explanatory information of a commodity or service or the like given by a provider of the commodity or service or the like or an intermediary, or a provider of the settlement means or the like. The description information corresponds to "witness" given by the provider with respect to the event, and may include, for example, information published on a Web site providing goods, services, or the like, or any content such as a description or remark input by the provider. The electronic signature of the event attestation system 1 (more precisely the issuer of the NFT) may be used further or instead. For example, the information corresponding to the witness may be issued in an ID token format of OpenID Connect, an Assertion format used in SAML (Security Assertion Markup Language), or Verifiable Credentials format.

The wallet managing section 14 has a function of managing the account number (wallet 41) of the user 2 on the blockchain 4, issuing the relevant NFT certifying the event to the wallet 41, and querying the NFT held in the wallet 41 or presenting to a third party. When the NFT related to the certification event is issued, the certification information acquired or collected by the certification processing unit 13 is given to the attribute information by the intelligent contract function of the blockchain 4. The presence of the certification information-related event can be certified by presenting the NFT (and certification information given as attribute information).

The user 2 accesses the wallet managing unit 14 via the UI processing unit 11, registers and identifies the address of the own account (wallet 41) in advance, and can access the own wallet 41. The access method of the wallet 41 differs depending on the specification of the blockchain 4, and the third party management type (online management type, online wallet) wallet is in a form of access via management like the wallet management section 14 as described above, but the self management type (local management type) wallet is in a form of access directly from the user terminal 21 to the wallet 41 without via the wallet management section 14 or the like.

< processing flow >)

Fig. 2 is a flowchart schematically showing an example of the event certification processing flow in the embodiment of the present invention. First, the user 2 accesses the UI processing part 11 via the user terminal 21, selects, for example, a commodity or service related to an event such as drawing, horse ticket, or donation, and issues a request for purchase, and performs a related process such as purchase by the UI processing part 11 (S01). Subsequently, a further settlement or payment request is issued, and the settlement processing unit 12 performs a settlement process (S02).

After the settlement processing is completed, the certification processing unit 13 determines whether or not the settlement-related event belongs to a certification target of the user 2 (S03). As described above, the determination may be performed based on a condition set in advance by the user 2, a seller such as a commodity, or the like, or may be performed based on an instruction issued by the user 2 for the settlement. When the related event is judged not to belong to the proving object, the proving processing of the event is ended.

On the other hand, when it is determined that the related event belongs to the certification target, the certification processing unit 13 acquires certification information for certifying the event (S04). As described above, the user may receive input of a description, remarks, or the like from a provider of the purchased commodity or the like or from a provider of the settlement means. Then, the wallet managing section 14 gives the certification information acquired in step S04 as the attribute value of the NFT by using the smart contract function of the blockchain 4, and issues the relevant NFT of the event to the wallet 41 (S05), thereby ending the certification process of the event.

In this case, when the holder of the account number for issuing the NFT (deploying the NFT smart contract) is not the same person (individual or organization) who has convinced the certification information, not only the certification information itself but also a private key signature that has been held by the person who has convinced the certification information may be given to the NFT attribute value. That is, if the provider of the commodity or the provider of the settlement means holds the private key s of the public key code alone, sign (s, p) may be calculated on the authentication information p using the signature algorithm Sign, and the calculation result may be added as the NFT attribute value. In addition, the operation of registering signature Sign (s, p) as the NFT attribute value may be omitted under the condition that a person who has convinced the certification information is the same as, for example, the holder of the account number that issued the NFT.

In addition, in the above-described step S01, when the user 2 performs the processing related to purchase or the like, the configuration of accessing the UI processing part 11 via the user terminal 21 is adopted, and as described above, the case where the UI processing part 11 can be connected to an external EC website is described, but the configuration is not limited thereto.

For example, in the process of selecting and purchasing a commodity or the like by the user 2 directly accessing the EC website using a Web browser or the like, not shown, of the user terminal 21, objects such as check boxes capable of requesting event-related proofs are provided through a purchase screen or the like on the EC website. When the user 2 requests the certification of an event such as purchasing a commodity, the EC website receives the request, and after completion of the settlement processing with the financial institution 3, the request for the certification of an event including information required for the certification of the event (NFT issue) is transmitted to the event certification system 1 via an API or the like, and the processing of steps S04 and S05 described above is performed.

With this configuration, at least a part of the functions of the UI processing unit 11 and the settlement processing unit 12 in fig. 1 are provided by the system of the external EC website, and are not required to be provided by the event certification system 1. Next, the user 2 may register information of his own account number (wallet 41) in the event certification system 1 instead of the information of the wallet 41 in the member information of the user 2 on the EC website, and when the EC website transmits a request for event certification to the event certification system 1 through the API, the information of the wallet 41 is simultaneously transmitted, and the processing (NFT issuance) on the blockchain 4 is performed using the information in the event certification system 1.

The configuration may be adopted in which the user 2 does not register information of the account number (wallet 41), but the wallet 41 is newly issued by the EC website or the event certification system 1, and processing on the blockchain 4 (NFT issuance) is performed using the information of the wallet 41. In this case, it is also possible to adopt a constitution in which information of the wallet 41 is transmitted to the user 2 in the final process of the event certification processing, and the certification information (NFT) of the event is acquired by querying on the blockchain 4 using the information of the wallet 41 received by the user terminal 21.

In the above example, the wallet 41 is newly issued for the purpose of issuing the NFT, and the wallet 41 may be newly issued each time a commodity or the like is purchased or the NFT is issued, and the same wallet 41 may be used for issuing the NFT even when the same user 2 subsequently issues the NFT. In either case, since a plurality of NFTs exist after the user 2 issues a plurality of NFTs or uses a plurality of identical EC websites, it is recommended that information be held in a plurality of wallets 41 issued to the user 2 in an application program or EC website on the user terminal 21.

In the present embodiment, the wallet managing unit 14 may query the NFT held in the wallet 41 or present it to a third party, as described above, and may be configured to acquire the attestation information (NFT) of the event by directly querying the blockchain 4 with the information of the wallet 41 received by the user terminal 21. Further, the user 2 may give an object (link, button, etc.) for querying the NFT to the posting content of an external content providing website such as a blog, an instragram (registered trademark), a YouTube (registered trademark), etc. It is possible to employ a constitution in which, after a user who browses the contents presses the object, an external content providing website of the object can query NFT using information of the wallet 41 held in association with the object, and the query result is transmitted and displayed to the user.

As described above, according to the event certification system 1 of the embodiment of the present invention, by capturing the settlement behavior performed on or accompanying the event as the certification target, and issuing the NFT as the certification information including the remarks on the settlement target, the event content, and the like, the related information NFT of the event in which the individual information itself does not have value is converted into the related information NFT, and the certification can be performed to the third party on the event independently of the arrival and arrival of the item or the value.

The invention completed by the present inventors has been specifically described above based on the embodiments, but the invention is not limited to the above embodiments, and various modifications may be made without departing from the gist thereof. The above-described embodiments are described in detail for the purpose of facilitating understanding of the present invention, but are not limited to the configuration in which all the components described are necessarily provided. In addition, with respect to a part of the configuration of the above embodiment, addition, deletion, and substitution of other configurations can be performed.

In addition, part or all of the above-described respective components, functions, processing units, processing means, and the like may be realized in hardware by, for example, designing in an integrated circuit. The above-described respective components, functions, and the like may be realized in a software manner by a processor interpreting and executing a program for realizing the respective functions. Information such as programs, tables, and files for realizing the respective functions can be stored in a recording device such as a memory, a hard disk, and an SSD, or in a recording medium such as an IC card, an SD card, and a DVD.

In the above figures, the control lines and the information lines are shown in consideration of the description, and not necessarily all the control lines and the information lines are shown on the mounting. In practice, it is believed that nearly all of the components may be interconnected.
