Description

Automatic authentication method for ownership of continuously usable NFT ticket based on consortium blockchain network}

The present invention relates to a method for automatically authenticating the ownership of NFT tickets that can be continuously utilized based on a consortium blockchain network. More specifically, the basic digital personality or object of a specific collection that can be traded and gifted to anyone using NFT ( (hereinafter abbreviated as 'NFT Collection') is created, and based on this, detailed utilities such as additional admission tickets, use (use) tickets, priority tickets, exchange tickets, and identity tickets of the NFT collection (hereinafter abbreviated as 'NFT Ticket') are created. (Decided to do so) is not limited to a one-time use, but can be set, consumed, and traded continuously, so that only the owner of the NFT collection is the legitimate authority to purchase or use the NFT ticket, thereby providing legitimate proof of ownership of the NFT ticket and its value due to scarcity. It is about an automatic authentication method for sustainable NFT ticket ownership based on a consortium blockchain network that enables target marketing of elevated or de-identified personal information.

Blockchain is a P2P (Peer-to-Peer) system based on a distributed ledger that can execute smart contracts. It is a distributed data storage environment called a ‘block’ formed by linking small data. It is a distributed data storage technology that stores management data and is used to record transactions of digital assets. In other words, blockchain represents a digital ledger in which transaction details that occur between network users are shared and stored among network members. Transaction details that occur between users over a certain period of time are recorded by more than half of the users. Transaction details that are confirmed and confirmed through consensus are bundled into one block and stored in the blockchain. In order to change the transaction history included in a block connected to such a blockchain, the consensus of more than half of the users must be obtained again for the block and all blocks connected after the block, so it is difficult to arbitrarily change the transaction history stored in the blockchain. This makes it virtually impossible for data stored on the blockchain to be forged or altered. Therefore, the reliability of data stored in blockchain is very high.

These blockchains are divided into public blockchains, private blockchains, and consortium blockchains. In particular, only pre-selected nodes can participate in consortium blockchains, and all participating nodes operate. As a half-center blockchain, a single entity does not control all nodes, so it has higher transparency than a private blockchain, and only pre-selected nodes can participate, making network expansion easier and transaction speed faster than a public blockchain. It has the advantage of being fast.

On the other hand, NFT (Non-Fungible Token) refers to a non-fungible token issued by giving a unique recognition value to a digital asset using blockchain technology. It is based on blockchain, so it is not related to ownership and transaction history. All information is stored in the blockchain, and it is used in various fields as a kind of certificate of authenticity and ownership of digital assets that proves the uniqueness and scarcity value of digital assets.

NFT tickets, which are recently being issued using these NFTs, are a one-time method of storing existing mobile tickets on the blockchain, such as admission or use rights to film festivals or exhibitions, identity rights or priority rights for seminars, or use rights or exchange rights for general stores or companies. The issuance of branded NFT tickets is increasing.

However, in the case of these existing NFT tickets, there were problems with automatic authentication of legitimate authority, problems with scalping or negative use of tickets being traded at a higher price than the initial issuance price based on the value formed in the ticket after ticket issuance, or membership. Issues such as unreasonable usage rights restrictions due to one-time use of NFT tickets also occurred. In addition, in the case of existing NFT tickets, there were problems such as making public access impossible because payment was made through cryptocurrency.

Therefore, the present invention is intended to solve the above problems, and the technical problem to be solved by the present invention is to create an NFT collection that can be traded and gifted to anyone using NFT, and to provide detailed utility of the NFT collection based on this. It is not limited to a one-time use but allows for continuous setup, consumption, and trading so that only the owner of the NFT collection is the legitimate authority to purchase or use the corresponding NFT ticket, thereby providing legitimate proof of ownership of the NFT ticket, increase in value due to scarcity, or non-identification. It enables target marketing of personal information and provides various rights to users through convenient UI (User Interface)/UX (User eXperience), while maximizing the effect of blockchain technology in the real world and continuously utilizing it. The goal is to provide an automatic authentication method for sustainable NFT ticket ownership based on a consortium blockchain network that can contribute to increasing the utility of NFT tickets.

One embodiment of the present invention for achieving the above object is an NFT ticket ownership authentication method in an NFT ticket management system that registers and trades NFT tickets in the distributed ledger of the consortium blockchain, including user ID and password for membership registration. When creating, a service key for logging in to the NFT ticket management system is created, linked to the user ID, and stored in the distributed ledger of the consortium blockchain. When the user ID and password are entered for user authentication, the service key is stored in the distributed ledger of the consortium blockchain. An identity verification step that performs user internal authentication by mapping the user ID, and when applying for registration or issuance of an NFT ticket by an identity-proven user, the ownership information of the NFT collection for the user is confirmed and the ownership information of the NFT collection is verified. If there is an NFT ticket registration/issuance step of receiving utility information for NFT ticket registration or issuance, generating or minting the corresponding NFT ticket and registering it in the distributed ledger of the consortium blockchain, the consortium blockchain network is continuous. This is a usable NFT ticket automatic ownership verification method.

The continuously usable NFT ticket automatic ownership authentication method based on the consortium blockchain network according to an embodiment of the present invention includes ownership information of the NFT collection for the user when requesting an auction or purchase of an NFT ticket by an identity-proven user. After confirmation, if there is ownership information of the NFT collection, the winning bid or transaction of the NFT ticket is processed, and the corresponding change information of the NFT ticket is processed through the individual's My Page, and the NFT ticket is stored and managed in the distributed ledger of the consortium blockchain. An NFT that further includes a management/transaction step or authenticates the user's NFT ticket ownership while maintaining minimal communication through a mobile application to prevent errors in transferring NFT ticket ownership upon a request for confirmation of NFT ticket ownership by an identity-proven user. It further includes a ticket ownership confirmation step, or it further includes an administrator authority setting and proof step of setting and proving administrator authority by receiving administrator information according to a request for authority setting and proof by an identity-proven NFT ticket manager, or NFT ticket It may be implemented in different embodiments, each further including a QR code recognition step of the NFT ticket that performs authority authentication of the NFT ticket through recognition of the QR code of the NFT ticket by an external device communicatively connected to the management system.

According to the present invention, an NFT collection that can be traded and gifted to anyone is created using NFT, and based on this, detailed utilities such as additional admission tickets, use rights, priority rights, exchange tickets, and identity rights of the NFT collection are used. NFT tickets can be set, consumed, and traded on an ongoing basis rather than just as a one-time purchase, so that only the NFT collection owner is the legitimate authority to purchase or use the NFT ticket, providing legitimate proof of ownership of the NFT ticket, and It provides the advantage of increasing value or enabling target marketing of de-identified personal information.

In addition, according to the present invention, it is possible to authenticate and authorize NFT tickets based on consortium blockchain, thereby providing various rights to users through convenient UI/UX while maximizing the effect of incorporating blockchain technology into the real world. It can contribute to increasing the utility of NFT tickets that can be used sustainably.

In addition, according to the present invention, NFT tickets are simply QR coded and NFT ticket authentication is performed using a database that is interconnected with on-chain and off-chain, thereby preventing fraud such as encryption and duplicate checks of NFT tickets.

Terms or words used in this specification and claims are not to be construed limited to their ordinary or dictionary meanings, and the inventor can appropriately define the concept of terms to explain his or her invention in the best way. It must be interpreted based on the meaning and concept consistent with the technical idea of the present invention. Therefore, it is understood that the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention, and that there may be various equivalents and modifications that can replace them at the time of filing this application. shall.

Figure 1 is a conceptual diagram illustrating the configuration of a consortium blockchain network for operating the present invention. The consortium blockchain network 10 consists of a master node 11 and at least one member node 12.

The master node (11) is a node that configures and manages the consortium blockchain network. When a random node wants to participate in the consortium blockchain network, the node to participate must include the node's user information, NFT collection information or NFT ticket information associated with the node, Node verification information, including electronic signature information, is requested, nodes are verified based on the node verification information received from the node, and only verified nodes are allowed to participate as member nodes (12) in the consortium blockchain network. At this time, the NFT collection information or NFT ticket information associated with the node may include utility information for proving ownership of the ticket that requires NFT ticket creation.

In addition, the master node 11 can grant or limit the authority of each member node within the consortium blockchain network based on the node information of the member nodes 12 participating in the consortium blockchain network. The authority of these member nodes (12) is the user or purchaser who purchases administrator rights, ownership, or usage rights to manage, register, and maintain NFT collections based on the consortium blockchain network for proof of ownership of NFT tickets ( buyer) may have authority. Member nodes can have one or more of these roles.

Member nodes (12) are nodes that participate in the consortium blockchain network and form the consortium blockchain network. They can create and distribute blocks within the consortium blockchain network, and provide services for the NFT ticket management system within the consortium blockchain network. may be provided or received. That is, these member nodes 12 provide or receive the services of the NFT ticket management system within the consortium blockchain network based on authority granted or limited by the master node 11 (e.g. administrator authority, user or buyer authority). Information on blocks distributed in the consortium blockchain network may be accessed or the scope of access may be restricted.

Figure 2 is an operation flowchart of a continuously usable NFT ticket automatic ownership authentication method based on a consortium blockchain network according to the present invention, and Figures 3a to 3c are detailed operation flowcharts of the main steps of Figure 2, according to an embodiment of the present invention. As illustrated in Figure 2, the NFT ticket automatic ownership authentication method may include an identity verification step (S110), an NFT ticket registration/issuance step (S120), an NFT ticket management/transaction step (S130), and NFT ticket ownership. It may be implemented in another embodiment, including at least one of the confirmation step (S140), the administrator authority setting and proof step (S150), or the QR code recognition step of the NFT ticket (S160). This NFT ticket automatic ownership authentication method of the present invention can be performed or operated by an NFT ticket management system that registers and trades NFT tickets in the distributed ledger of the consortium blockchain.

In the identity verification step (S110), as illustrated in Figure 3a, when the membership application (S111) and the user ID and password for the same are generated (S112), a service key for logging in to the NFT ticket management system is generated (S113) to allow the user The membership registration stage (S111-S114) is linked to the ID and stored in the distributed ledger of the consortium blockchain (S114), and when the user ID and password for user authentication are entered, the service key and user are stored in the distributed ledger of the consortium blockchain. It includes an internal authentication step (S115-S118) that performs internal user authentication by mapping IDs.

The membership registration stage (S111-S114) is a stage carried out in response to a membership registration request by a random node user who wishes to participate in the consortium blockchain network, and the master node 11 sends user information, node information, and node information to the corresponding node requesting membership. Request node verification information, including NFT collection information and electronic signature information associated with the corresponding node, and verify the node based on the node verification information received from the node. Only verified nodes are member nodes in the consortium blockchain network. Participate in (12). At this time, when the user ID and password for a random node are generated, the master node 11 uses a private key and a public key as service keys based on the consortium blockchain network necessary for registration and transactions of NFT collections. The service key is generated internally, linked internally with the user ID, and stored in the consortium blockchain network. Accordingly, in the NFT ticket management system for automatic authentication of NFT ticket ownership of the present invention, the public key and private key, which are service keys necessary for service use and very important for network security, are generated and stored inside the master node 11, so external member nodes (12) is not exposed at all, and therefore there is no risk of the service key, which is very important for network security, being leaked or lost through printed matter, etc., thereby improving network security.

In addition, in the NFT ticket management system for automatic authentication of NFT ticket ownership of the present invention, the service key is not individually owned or stored by the user of each member node 12, and the consortium block is created by simply storing the user ID and password. By making it possible to use the service of the chain-based NFT ticket management system, convenience of use can be improved.

The internal authentication step (S115-S118) is a step performed in response to a user authentication request from a member node (12) participating in the consortium blockchain network. A user login request (S115) from the member node (12) and a user ID and When entering a password (S116), the master node (11) authenticates the user by internally mapping the service key (private key and public key) linked to the user ID stored in the consortium blockchain network with the entered user ID (S117). It is performed (S118). At this time, the master node 11 authenticates the user ID input from the member node 12 by internally mapping it with the private key of the service key linked to the user ID stored in the consortium blockchain network, thereby authenticating the NFT ticket of the present invention. In the NFT ticket management system for automatic authentication of ownership, network security can be improved by ensuring that the service key, which is necessary for service use and is very important for network security, is not exposed to external member nodes 12 even during user authentication.

As illustrated in Figure 3b, the NFT ticket registration/issuance step (S120) verifies the ownership information of the NFT collection for the user according to the application for registration or issuance of the NFT ticket (S121) by the user whose identity is verified (S122). And, if there is ownership information for the corresponding NFT collection (Y branch of S123), utility information for NFT ticket registration or issuance is uploaded (S124) and the corresponding NFT ticket is created or minted (S125) to decentralize the consortium blockchain. This is the step of registering in the ledger (S126). This NFT ticket registration/issuance step (S120) is a step performed in response to a request for registration or issuance of an NFT ticket by a user. When an application for registration or issuance of an NFT ticket is received from the member node 12, the master node 11 First, the ownership information of the NFT collection for the user is first checked, and if the user has ownership information of the NFT collection, the ticket information for NFT ticket registration or issuance is uploaded from the member node 12 and the corresponding NFT ticket is uploaded. is created or minted, and the created or minted NFT ticket is registered in the member node's My Page and the distributed ledger of the consortium blockchain. As a result, the automatic authentication method for NFT ticket ownership of the present invention can encourage continuous use of NFT collections or NFT tickets, and thus provide users with various rights through convenient UI/UX, thereby integrating blockchain technology into the real world. The effect can be maximized and it can contribute to increasing the utility of NFT tickets that can be continuously used through target marketing using legitimate proof of ownership of NFT tickets, increased value due to scarcity, or non-identified personal information.

At this time, when creating or minting an NFT ticket, the master node 11 can classify and code the utility information of the NFT ticket by item as illustrated in Figure 4 and store it in a database that is interconnected with on-chain and off-chain, and the utility of the NFT ticket The information may include utility issuance information that records issuance history, utility transaction information that records transaction history, and utility authentication information that records authentication history. Here, the utility issuance information of the NFT ticket includes utility ID, collection ID, director ID, utility name, thumbnail, parent category, number of uses, expiration date, number of issues, issue price, and issue date information as illustrated in Figure 5. NFT ticket utility transaction information may include utility ID, collection ID, NFT ID, previous owner ID, current owner ID, transaction type (sale/gift), transaction price, transaction date and time information, and NFT The ticket's utility authentication information may include utility ID, NFT ID, current owner ID, authentication start date, authentication end date, and validity information.

As illustrated in Figure 3c, in the NFT ticket management/transaction step (S130), if there is an auction or purchase request (S131) for an NFT ticket by an identity-proven user, the ownership information of the corresponding NFT collection for the user is checked (S132). If there is ownership information for the NFT collection (Y quarter of S133), the NFT ticket will be successfully bid or traded (S134), and when the auction or transaction is completed (Y quarter of S135), the corresponding NFT ticket change information will be posted to each individual's My Page. This is the step of processing changes (S136) and then storing and managing them in the distributed ledger of the consortium blockchain (S137). This NFT ticket management/transaction step (S130) is a step that is carried out according to an NFT ticket auction or purchase request by the user. When an application for auction or purchase of an NFT ticket is made from the member node 12, the master node 11 first The ownership information of the relevant NFT collection for the relevant user is first confirmed, and if the user has the ownership information of the relevant NFT collection, a transaction for auction or purchase of the requested NFT ticket is performed and the winning bid or transaction is completed according to the auction or purchase. In this case, the transaction information resulting from the successful bid or purchase is registered in the member node's My Page and the distributed ledger of the consortium blockchain. As a result, the automatic authentication method for NFT ticket ownership of the present invention can encourage continuous use of NFT collections or NFT tickets, and thus provide users with various rights through convenient UI/UX, thereby integrating blockchain technology into the real world. The effect can be maximized and it can contribute to increasing the utility of NFT tickets, which can be continuously utilized through target marketing using legitimate proof of ownership of NFT tickets, increased value due to scarcity, or non-identified personal information.

The NFT ticket ownership confirmation step (S140) is a step of authenticating the user's NFT ticket ownership through a mobile application (e.g., ownership proof API) in response to a request for confirmation of NFT ticket ownership by an identity-proven user. This NFT ticket ownership confirmation step (S140) is a step carried out in response to a request for confirmation of NFT ticket ownership by a user whose identity has been verified through a mobile application, and minimal communication is maintained through the mobile application to prevent errors in transferring NFT ticket ownership. This authenticates the user's ownership of the NFT ticket.

The administrator authority setting and proof step (S150) is a step of setting and proving administrator authority by receiving administrator information according to the authority setting and proof request by the identity-proven NFT ticket manager. The administrator's authority related to various performances and events is set and proven. This is the setup and proof stage, and can be done off-chain regardless of on-chain. When authenticated by linking with an external device, it is converted to a QR code, and administrator information is input to set and prove administrator authority.

The QR code recognition step (S160) of the NFT ticket is a step of performing authority authentication of the NFT ticket through recognition of the QR code of the NFT ticket by an external device communicatively connected to the NFT ticket management system. In the QR code recognition step (f) of these NFT tickets, kiosks, tablets, smartphones, and PCs can be used as external devices communicatively connected to the NFT ticket management system. Authorization of the NFT ticket includes an admission (or invitation) right, It is possible to authenticate any one of the following rights: use (or use) right, priority (or reservation) right, exchange (or payment) right, and identity right.

The operation and effects of the sustainable NFT ticket ownership automatic authentication method based on the consortium blockchain network of the present invention configured as described above and its effects are described as follows.

First, in the identity verification step (S110), as illustrated in Figure 3a, when a membership application is made by a random node user who wants to participate in the consortium blockchain network, user information and secrets are provided to the corresponding node requesting membership. Request node verification information including number, NFT collection information associated with the node, electronic signature information, etc. from the node and verify the node based on the node verification information received from the node. Consortium blockchain network only for verified nodes participate as a member node (12). At this time, when creating a user ID and password for a random node, the master node 11 internally generates a consortium blockchain network-based service key required for registration and trading of NFT collections, links it to the user ID, and stores it in the consortium blockchain network. Therefore, the service key, which is necessary for using the service of the NFT ticket management system for automatic authentication of NFT ticket ownership of the present invention and is very important for network security, is not exposed to the external member node 12 at all, and therefore is very important in terms of network security. It is possible to fundamentally block the risk of external leakage or loss of important service keys, thereby improving network security.

Next, when there is a login request and user ID and password input from a member node participating in the consortium blockchain network, the master node internally maps the user ID entered from the member node and the service key stored in the distributed ledger of the consortium blockchain to internally connect the user. Authentication is performed. At this time, the master node 11 authenticates the user ID input from the member node 12 by internally mapping it with the private key of the service key linked to the user ID stored in the consortium blockchain network, so the NFT ticket of the present invention is owned. In the NFT ticket management system for automatic authentication, the service key, which is necessary for service use and is very important for network security, is not exposed to external member nodes 12 even during user authentication, thereby improving network security.

Afterwards, in the NFT ticket registration/issuance step (S120), as illustrated in Figure 3b, when there is an application for registration or issuance of an NFT ticket (S121) by an identity-proven user, the master node retains ownership of the NFT collection for that user. Check the information first (S122, S123), and if you are a user with ownership information for the NFT collection, upload utility information for NFT ticket registration or issuance (S124) and create or mint the corresponding NFT ticket (S125). , the generated or minted NFT ticket is registered (S126) in the member node's My Page and the distributed ledger of the consortium blockchain. As a result, the automatic authentication method for NFT ticket ownership of the present invention can encourage continuous use of NFT collections or NFT tickets, and thus provide users with various rights through convenient UI/UX, thereby integrating blockchain technology into the real world. The effect can be maximized and it can contribute to increasing the utility of NFT tickets, which can be continuously utilized through target marketing using legitimate proof of ownership of NFT tickets, increased value due to scarcity, or non-identified personal information.

At this time, when creating or minting an NFT ticket, the master node 11 classifies and codes the utility information of the NFT ticket by item as illustrated in Figure 4 and stores it in a database that is interconnected with on-chain and off-chain.

Meanwhile, in the NFT ticket management/transaction step (S130), as illustrated in FIG. 3c, when there is an auction or purchase request (S131) for an NFT ticket by an identity-proven user, the master node 11 first First, check the ownership information of the NFT collection (S132, 133), and if you are a user who has the ownership information of the NFT collection, proceed with a transaction for auction or purchase of the requested NFT ticket (S134) to win or win the auction or purchase. When the transaction is completed (Y quarter of S135), the transaction information related to the winning bid or purchase is registered (S136, S137) in the member node's My Page and the distributed ledger of the consortium blockchain. As a result, the automatic authentication method for NFT ticket ownership of the present invention can encourage continuous use of NFT collections or NFT tickets, and thus provide users with various rights through convenient UI/UX, thereby integrating blockchain technology into the real world. The effect can be maximized and it can contribute to increasing the utility of NFT tickets, which can be continuously utilized through target marketing using legitimate proof of ownership of NFT tickets, increased value due to scarcity, or non-identified personal information.

Meanwhile, in the NFT ticket ownership confirmation step (S140), in response to a request for confirmation of NFT ticket ownership by an identity-proven user, the user's NFT ticket ownership is authenticated through a mobile application to prevent errors in transferring NFT ticket ownership.

Meanwhile, in the administrator authority setting and proof step (S150), administrator information is input according to the authority setting and proof request by the identity-proven NFT ticket manager related to various performances and events, and administrator authority is set and proven. The setup and proof step (S150) can be done off-chain regardless of on-chain, and is converted to a QR code when authenticated by linking with an external device, and administrator information is input to set and prove administrator authority.

Lastly, in the QR code recognition step (S160) of the NFT ticket, the authority of the NFT ticket is recognized through the QR code recognition of the NFT ticket by an external device such as a kiosk, tablet, smartphone, or PC that is communicatively connected to the NFT ticket management system. In other words, one of the following rights is authenticated: entrance (or invitation) right, use (or use) right, priority (or reservation) right, exchange (or payment) right, and identity right.

Accordingly, according to the present invention, an NFT collection of a specific collection that can be traded and gifted to anyone is created using NFT, and based on this, additional admission tickets, use rights, priority rights, exchange rights, identity rights, etc. of the NFT collection are created. NFT tickets for detailed utility are not limited to one-time use, but can be set, consumed, and traded continuously, so that only the owner of the NFT collection is the legitimate authority to purchase or use the NFT ticket, providing legitimate proof of ownership of the NFT ticket, It provides the advantage of increasing value due to scarcity or marketing by targeting non-identified personal information.

In addition, according to the present invention, it is possible to authenticate and authorize NFT tickets based on consortium blockchain, thereby providing various rights to users through convenient UI/UX while maximizing the effect of incorporating blockchain technology into the real world. It contributes to increasing the utility of NFT tickets that can be used sustainably.

In addition, according to the present invention, NFT tickets are simply QR coded and NFT ticket authentication is performed using a database that is interconnected with on-chain and off-chain, thereby preventing fraud such as encryption and duplicate checks of NFT tickets. Easy entry is possible through QR code authentication of the ticket, preventing fights, and providing the advantage of enabling crowd management by calculating real-time density through digital tracking.
