OWNERSHIP AND COPYRIGHT INTEGRATING NFT SYSTEM BASED ON BLOCKCHAIN IN METAVERSE PLATFORM
An ownership and copyright integrating non-fungible token (NFT) system based on blockchain in a metaverse platform includes an input unit configured to receive NFT information on content based on an NFT, a token management unit configured to generate an NFT matching the received NFT information and provide a history management service for the NFT, rights holder authentication unit configured to integrate ownership and copyright in an equal share ratio and providing the integrated ownership and copyright to a user corresponding to the generated NFT, and a token transaction unit configured to perform NFT transaction with other users on the metaverse platform by using transaction information input by a rights holder to whom the ownership and copyright are provided, generate transaction completion information when NFT transaction is completed, and broadcast the transaction completion information to a blockchain network.
1 . An ownership and copyright integrating non-fungible token (NFT) system based on blockchain in a metaverse platform, the ownership and copyright integrating NFT system comprising:
an input unit configured to receive NFT information on content based on an NFT;
a token management unit configured to generate an NFT matching the received NFT information and provide a history management service for the NFT;
a rights holder authentication unit configured to integrate ownership and copyright in an equal share ratio and providing the integrated ownership and copyright to a user corresponding to the generated NFT; and
a token transaction unit configured to perform NFT transaction with other users on the metaverse platform by using transaction information input by a rights holder to whom the ownership and copyright are provided, generate transaction completion information when NFT transaction is completed, and broadcast the transaction completion information to a blockchain network,
wherein the token transaction unit performs a sale for shares of a requested transaction while performing a sequentially rotation when multiple rights holders request a sale for token transaction.
2 . The ownership and copyright integrating NFT system of claim 1 , further comprising:
a digital wallet management unit configured to collect NFT information held by the multiple rights holders and usage rights information on digital wallets set by each of the multiple rights holders and configured to perform conversion management between a hot wallet and a cold wallet.
3 . The ownership and copyright integrating NFT system of claim 1 , wherein
the token transaction unit performs the sale in an equal share unit of the multiple rights holders while performing the sequential rotation.
4 . The ownership and copyright integrating NFT system of claim 1 , wherein
the token transaction unit performs the sale in proportion to share ratios owned by the multiple rights holders while performing the sequential rotation.
5 . The ownership and copyright integrating NFT system of claim 3 , wherein
a minimum transaction unit of the shares is 0.01%, and the multiple rights holders performs the sale by 1% for each rights holder while performing the sequential rotation.
6 . The ownership and copyright integrating NFT system of claim 4 , wherein
a minimum transaction unit of the shares is 0.01%, and the multiple rights holders performs the sale by 1% for each rights holder while performing the sequential rotation.
7 . The ownership and copyright integrating NFT system of claim 1 , wherein
the token transaction unit automatically notifies other rights holders of share price per % when a largest share holder among the multiple rights holders determines the share price per %, automatically activates a transaction of a corresponding rights holder when the share price per % is included in a share price range directly set by another rights holder, and automatically deactivates transaction activation setting for the corresponding rights holder when the share price per % is not included in the set share price range.
8 . The ownership and copyright integrating NFT system of claim 7 , wherein
the token transaction unit deactivates the transaction of another rights holder who does not agree with the share price per % when the largest share holder among the multiple rights holders determines the share price per %.
9 . The ownership and copyright integrating NFT system of claim 8 , wherein,
when the largest share holder is not engaged in the transaction for a certain period of time while the share price per % is determined, the token transaction unit releases the transaction activation settings of all rights holders and determines the share price per % based on an average profit of a corresponding content for a certain period of time for the content through an automatic valuation method.
10 . The ownership and copyright integrating NFT system of claim 9 , wherein,
in the automatic valuation method, each rights holder sets the shares for transaction again to request a sale.
11 . The ownership and copyright integrating NFT system of claim 10 , wherein,
in the automatic valuation method, transaction activation settings of all rights holders are maintained even when the largest share holder is not engaged in the transaction for a certain period of time.
12 . The ownership and copyright integrating NFT system of claim 1 , wherein
the NFT information includes at least one of content information including an image, a video, music, modeling, digital real estate, and a game, information in which copyright and ownership of content are integrated, and share ratio information of a rights holder and other users.
13 . The ownership and copyright integrating NFT system of claim 12 , wherein
the token management unit generates an NFT to which a random unique key is assigned in response to the NFT information, matches the generated NFT to integrated copyright and ownership information, and stores the matched information, and detects external access or abnormal access by using the random unique key assigned to the NFT.
14 . The ownership and copyright integrating NFT system of claim 13 , wherein
the token transaction unit restricts authority to download NFT content-related supporting documents, access big data, search for information, and information inquiry and transaction according to the share ratio information of the rights holder and other users.
15 . The ownership and copyright integrating NFT system of claim 14 , wherein
the token transaction unit collects share information, marketable share information, and price information corresponding to a share for the NFT content received from a user terminal of the rights holder, and performs a transaction for the NFT based on the collected share information, the marketable share information among total shares, and the price information.
16 . The ownership and copyright integrating NFT system of claim 15 , wherein,
when the token transaction unit receives a request for NFT transaction and ownership transfer from the user terminal of the rights holder, the token transaction unit performs authentication by using a unique key included in the NFT, and then performs the NFT transaction and the ownership transfer between the rights holder and the other users on a network.
17 . The ownership and copyright integrating NFT system of claim 2 , wherein,
when the digital wallet management unit receives a request for blocking information change for the NFT from a user terminal of the rights holder, the digital wallet management unit moves a corresponding NFT from a hot wallet to a cold wallet.
18 . The ownership and copyright integrating NFT system of claim 17 , wherein,
when profit for the NFT content is generated, the digital wallet management unit distributes a copyright fee to the rights holder in proportion to a share ratio.
