Description

A System that Converges the Original and Non-Fungible Token (NFT) and Method Using the Same}

The present invention is a technology related to a system and method for combining a non-fungible token (NFT) and an original, and can be combined with artificial intelligence (AI) and the Internet of Things (IoT).

Technology for authenticating original works of art (works whose value as art is recognized, including archaeological data or historical relics) has not developed relatively vigorously. Authentication of the original, that is, 'whether the artwork was created by a specific subject' has been determined based on the empirical and intuitive judgment of a small number of experts, and the majority of artworks of relatively low value are original through the personal confirmation of the creator. Certification is in progress.

Whether a work of art is original is one of the most important factors to be considered in each stage, from the initial completion stage, to the stage of transfer to the initial purchaser, and to the stage of successive transfers. In particular, in the 'transfer' stage of art, which is the process after creation, the issue of authenticating the original includes 'whether the transfer is made by the true owner' as well as 'whether it is an artwork produced by the producer' or not. Doing so entails complex legal issues.

In this regard, blockchain technology, especially NFT (Non-fungible Token) technology based on Ethereum's ERC-721 protocol, is attracting attention as a promising technical alternative related to originality or original authentication. However, NFT technology itself does not solve the problem of originality or authentication of the original. NFT is issued in the form of issuing a token for each distinguishable unit and connecting external data such as a uri value to the token. In this case, if the external data connected to the uri value is a value specified by a protocol that cannot be manipulated, such as IPFS (InterPlanetary File System), it can be seen that a certain level of non-manipulation is guaranteed by issuing the NFT. However, NFT technology cannot give any answer to whether the external data linked to the uri value is the original even if the NFT is issued, and whether the issuing or owning account of the NFT has ownership of the original. The situation becomes even more serious when the external data itself is not the original, but a digital replica of a real physical object. In this case, the NFT technology does not give any answer to whether the physical object is the actual owner or whether the issuance, possession, or transfer of the NFT has any relation to the legal rights to the physical object, and rather the situation in which the rights are violated ( Example: When a subject that does not have any rights to the physical object issues an NFT).

The present invention is a system designed to solve these problems. That is, the present invention configures a combined relationship between 'original with physical substance' and 'NFT', (1) authentication of the original in the production stage, (2) authentication of the right holder in the transfer stage, and (3) production and transfer. It is a technology that enables a third party to check the certification details of the creation, transfer, change, and extinction of related rights.

In this regard, Korean Patent Registration No. 10-1812638 is disclosed as a prior art. A security device (Secure Element) that stores the certificate private key and unique ID issued when the module is created, and stores authentication information issued from the activation service server when purchasing the product; an encryption unit that encrypts the unique ID or authentication information with the certificate private key; and generating identification information including an encrypted unique ID when connected to a payment terminal, transmitting the generated identification information to the payment terminal, and including sales information and product information input through the payment terminal upon completion of unique ID authentication from the genuine certification service server. and a processor that receives authentication information, wherein the processor encrypts the authentication information including the sales information and the product information with the certificate private key through the encryption unit, and the security device encrypts the authentication information encrypted with the certificate private key. Disclosed is a genuine authentication module characterized by storing information and the unique ID encrypted with the certificate private key.

However, the aforementioned patent only uses a security device, which is separated from the product, that is, a work of art, and cannot fundamentally solve the concern about counterfeiting of the original work due to the high variability of the mark. In addition, there is a crucial difference from the present application in that it has nothing to do with advanced technology based on blockchain such as NFT. That is, in the above patent, the operation of the genuine authentication module is only driven through an encryption method, has nothing to do with the original, which is a physical entity, and has nothing to do with blockchain technology, especially with advanced blockchain technology such as NFT. has nothing to do with

In addition, there are many examples of utilization using the beacon technology of the present application, but no technology associated with the issuance and transfer of NFTs has been proposed to implement originality.

The specific content for carrying out the present invention will be described. The electronic authentication device {1000} of the present application is composed of a second memory device {102} attached to the original and a first memory device {101} that exists other than the original. The first and second memory devices store key values 1 and 2, which are symmetric encryption key values, respectively, and can store, transmit, and receive information, respectively. In some cases, the first and second beacon memory devices may be configured as beacons that meet the NFC standard and the Bluetooth standard. The second beacon memory device is necessarily coupled to the original, and it is generally appropriate to attach it to an invisible area of the original.

The electronic authentication device {1000} may be configured in conjunction with the electronic key master device {2000}, and the key value of each memory device of the electronic authentication device may be written, modified, or erased through the electronic key master device. However, It is preferable that the electronic key master device is configured to perform these operations only under certain constraints in conjunction with the outside.

The above operations are basically performed in the authentication processing server {3000}. The authorization processing server {3000} generates an encryption key pair of the first and second memory devices, and the first and second key values are finally stored through the electronic authentication device. Depending on the case, transmission/reception may be performed directly with the memory device or may be transmitted/received through the electronic key master device {2000}. Assuming that the work of art is a painting, if the original author stores and possesses the generated 2-key value in memory device 2, and the 1-key value is attached to memory device 1 and matches the painting in the final completion stage of the work of art, the painting In order to issue an NFT for , it is a prerequisite that the memory device No. 2 and the memory device No. 1 contact each other so that combined information of key values 1 and 2 is generated. The combined information of key values 1 and 2 is transmitted to the authentication processing server {3000}, and the NFT is issued to the account assigned to the original author in the blockchain network {4000}. Information about the work can be additionally used for NFT issuance through the authentication processing server. This process is of great significance to prevent the unauthorized issuance of NFTs. This is because when an NFT is issued by a subject other than the original creator, it is impossible to issue the NFT by using the value of the combination of key values 1 and 2 as the signature value for the final NFT issuance. In relation to this, the authentication unit performs a function of making it known that the NFT was issued with a combination of key values 1 and 2 through a hash function, etc. After the original creator issues the NFT, even if transfer becomes a problem, the values of keys 1 and 2 are still required. In principle, the original creator can hand over the number 2 memory device itself along with the transfer, and the NFT transfer also requires a final signature by a combination of key values 1 and 2. Key values 1 and 2 may be newly generated according to the selection of the transaction party. In this case, the authentication processing server {3000} has newly generated key values 1 and 2, and the corresponding values are input to the memory device 1. and the process can be processed, recorded, and stored through the blockchain network {4000}. If the above corresponding value is entered in relation to the transmission of the NFT, in combination with the authentication unit, key values 1 and 2 are newly issued without disclosing specific key values, and key values 2 are sent to the device combined with the original It has been entered, and according to the combination of the new key value, the transfer can be made in the future or the fact that it should be transferred can be disclosed. The above process can be combined with a smart contract to enable transfer as the fulfillment of specific conditions or as a division of rights. In addition, it is also possible to implement a function of allowing the first and second memory devices to have a function such as IoT and further strengthening authentication of the original by combining with location information.

The encryption method of the present application can be configured in various forms, but considering that art transactions must be secured for a very long period of time, it is appropriate to combine the strongest type of quantum resistance encryption technique. That is, in relation to the encryption of the present application, when using BIKE,

Under the above definition, key value 1 and key value 2 are,

will be implemented in the form

Regarding the signature, it utilizes a separate CRYSTALS-Dilithium algorithm and most simply,

form can be borrowed.
