Description

NFT electronic notary system and its operation method {SYSTEM FOR NFT ELECTRONIC NOTARY AND OPERATING METHOD THEREOF}

The present invention is related to an NFT notarization system, and specifically relates to a system that electronically notarizes a document provided online or offline using an unmodifiable NFT.

NFT is a virtual token that proves the owner of a digital asset using blockchain technology. By putting the address pointing to digital files such as pictures and videos in the token, it is used to indicate its unique originality and ownership. That is, it may be a kind of virtual certificate of authenticity.

Existing digital assets were easily copied without permission because they consisted only of data, and copy prevention technology using DRM (Digital Rights Management) also had a centralized management server that eventually distributed them.

In contrast, NFTs are not controlled by anyone using blockchain technology and have uniqueness that cannot be reproduced, so their scarcity can be fully recognized and they are relatively safer. As a result, various digital assets, including various works of art, are being produced and traded as NFTs.

On the other hand, notarization is widely used to publicly prove certain facts or legal relationships. Currently, users who want to obtain notarization have to endure the hassle of visiting a law firm for notarization. In addition, the cost and time required for notarization cannot be overlooked. In the case of a law firm, since even simple tasks such as notarization must be handled in person with the person requesting notarization, the efficiency of the work is reduced, and the services provided are subject to regional restrictions.

In order to solve these offline problems, a system for notarizing electronic documents online has been proposed, but it may not have the same legal effect as that provided by law firms, and when paper contract documents are notarized, there is a problem that it is difficult to preserve permanently for reasons such as loss or damage.

The present application is intended to solve the above-described problems with offline notarization. In order for the NFT notarization server of the present application to issue an electronic document or paper document as an NFT, the server manages the creation and request of NFTs and NFT management, so that users can permanently preserve and manage NFT services as notarized documents.

In step 310, the user terminal 110 may transmit the NFT electronic notarization request including the electronic document to the NFT notarization server 120. The user can transmit the electronic document to be notarized by including it in the NFT electronic notarization request.

The NFT notary server 120 may perform electronic seal on the received electronic document. Electronic sign-in can be collectively referred to as performing sign-in electronically. Electron incorporation can be performed in a variety of ways.

Specifically, the processor may sequentially arrange at least one page included in the electronic document received from the user terminal so that adjacent pages contact each other. When an adjacent page is arranged to be contacted, it can be considered ready to perform a causal, such as performing an causal offline.

The processor may display an electronic notarization mark between adjacent pages among the at least one arranged page to generate an electronic document displaying the electronic notarization mark. The processor may perform electronic authentication by transmitting an electronic document marked with an electronic notarization mark to the NFT minting system through a communication module. The present application has described the liver method as an embodiment, but is not limited thereto.

In step 320, the NFT notary server 120 may generate metadata corresponding to the electronic document for generating the NFT using the electronic document. Meta data may refer to data about an electronic document. Information such as the document's name, image link, royalty rate, original author, etc. can be included.

In step 330, the NFT notarization server 120 may transmit the electronic document and the meta data through the communication module so that the NFT minting system issues the NFT using the electronic document and meta data. Transmission of meta data may be performed through a wireless network.

In step 340, the NFT minting system 130 may transmit a fee payment request requesting payment for the NFT issuance fee. In step 350, the NFT notary server 120 may perform payment for the NFT issuance fee.

Payment for NFT issuance fees can be performed in various ways. For example, the NFT notary server 120 may transmit a payment request message to the user terminal through a communication module upon receiving the fee payment request. When a payment request message is transmitted to the user terminal 110, the user terminal 110 may perform payment for the NFT issuance fee through the user interface of the above-described application.

As described above, the NFT notary server 120 directly pays the NFT issuance fee with the NFT minting system 340, so that the user can perform NFT management and electronic notarization by the NFT notary server 120. This has the advantage of promoting user convenience through unification of performing entities.

In step 360, the NFT notarization server 120 may receive the issued NFT notarized document from the NFT minting system according to the payment of the NFT issuance fee. Specifically, the NFT notarization server 120 may receive the NFT electronic notarization document generated using the electronic document and the meta data from the NFT minting system through a communication module.

Receiving an NFT notarized document can be performed in a variety of ways. For example, an NFT notarized document can be sent with a QR code (Quick Response code) link or link address. Referring to FIG. 4 , the user terminal 110 may display a QR code 410 in which information on an NFT notarized document is stored, and a link 420 through the display 400 . The user may access the NFT electronic notarized document using at least one of a QR code and a link.

Referring to FIG. 5 , when a user accesses an NFT electronic notarized document, the NFT electronic notarized document may be displayed through the display of the user terminal 110 or 500 . A virtual address at which the issued NFT electronic notarized documents are stored may be displayed on the display, and electronic notarized documents 502 held by the user may be displayed through a user interface.
