Description

Method for managing digital content of NFT (Non-Fungible Token) and content management system using the same {METHOD FOR MANAGING NON-FUNGIBLE TOKEN DIGITAL CONTENTS FOR THE USE OF COPYRIGHT AND CONTENTS MANAGEMENT SYSTEM USING THE SAME}

The present invention relates to a method of managing digital content of NFT for application for use of copyright property rights and a content management system using the same. More specifically, the present invention relates to issuing and managing NFT using displaybone digital content edited from original digital content. It relates to a method of managing NFT digital content and a content management system using the same.

NFT is an abbreviation for Non-Fungible Token. While cryptocurrency tokens such as Bitcoin and Ethereum can be exchanged in the same amount, NFT is a unique smart contract address and token with each token using unique identification information. Because it has an ID, it has the characteristic of being non-replaceable with other tokens.

In addition, NFT can identify a specific asset or digital file according to the tag contained in the token, and can serve as proof of ownership and history of the asset by specifying ownership and transaction history through blockchain ledger technology.

In other words, NFT is a means of digitally tokenizing existing assets such as artwork and real estate, and is used to clarify ownership and liquidate assets by attaching an asset tag to tokens created using blockchain technology.

However, in order to create an NFT using a picture, video, photo, etc. as an asset, permission for use must be obtained from the copyright holder of the content, and depending on the type and scope of use, reproduction rights, performance rights, exhibition rights, distribution rights, and the right to create secondary works, etc. There is the inconvenience of having to obtain permission for each detailed copyright item.

In addition, there have been many cases of issuing NFTs without permission without seeking the consent of the copyright holder. These are all cases of copyright infringement, and there is a problem that such copyright infringement incidents are constantly occurring.

Additionally, due to the nature of the blockchain where all content is public, anyone can check the URL (Uniform Resource Locator) information where the digital content included in the NFT is stored, and the original digital content can be downloaded by accessing the URL at any time. There is a problem that cases of copyright infringement may occur.

In addition, even if you purchase an NFT and have ownership of the NFT, the transfer of copyright is generally not made. In this situation, if digital content is used for exhibition, rental, reproduction, etc., this is an infringement of reproduction rights, transmission rights, rental rights, and exhibition rights. This applies to cases.

In addition, when NFT digital content is displayed on a digital device, it is difficult to distinguish it from the original digital content, and even if NFT technology is incorporated to guarantee the uniqueness of the digital content and the owner of the digital content, it is done outside the NFT area. There is a problem that it is difficult to protect copyright because it is lost.

Therefore, improvement measures to solve the above problems are required.

The present invention aims to solve all of the above-mentioned problems.

Additionally, another purpose of the present invention is to prevent unauthorized use of digital content included in NFT.

Referring to FIG. 2, the content management system 1000 is a web/app service server (web/app service server) for receiving a signal from a content owner terminal or a content user terminal and transmitting the processing result for the received signal to the content owner terminal or content user terminal. 1100), a payment server 1200 for processing approval for use of copyright property rights according to the selection of the application menu for use of copyright property rights by referring to the content user information and content utilization information received from the content user terminal, information on selection of application menu for use of copyright property rights, copyright Use application management server (1300) and content management system (1000) to manage usage information such as usage form, usage space, usage period, user, etc. of digital content by referring to property rights usage approval information, a public blockchain external to the content management system (1000) An NFT issuing server (1400) for issuing NFTs and managing the issued NFTs through the NFT blockchain network (2100), and content corresponding to the content user terminal when accessing digital content using a token issued from the content user terminal. An access rights management server (1500) that verifies whether a user is a legitimate user and allows access to digital content to verified content users, and stores original digital content, display copy digital content, and duplicate digital content in a data storage system (2300). It may be configured with a data storage management server 1600 for storing and managing.

At this time, the payment server 1200, the application management server 1300, and the access rights management server 1500 of the content management system 1000 collect various information related to the use, permission, and use of the copyright property rights of the original digital content. It may be managed by storing it in a reliable storage system such as a database, or it may be managed by registering it in the content management blockchain network 2200.

In Figure 2, a web/app service server 1100, a payment server 1200, a usage application management server 1300, an NFT issuing server 1400, an access rights management server 1500, and a data storage management server 1600, respectively. Although shown as included in this content management system 1000. Each server may be separated from the content management system 1000 and configured as an individual system.

In addition, each of the web/app service server 1100, payment server 1200, use application management server 1300, NFT issuing server 1400, access rights management server 1500, and data storage management server 1600 is at least It may be a computing device including memory and a processor.

Specifically, a web/app service server (1100), payment server (1200), usage application management server (1300), NFT issuing server (1400), access rights management server (1500), data storage management server (1600), and Data storage system 2300 typically refers to a computing device (e.g., a device that may include a computer processor, memory, storage, input and output devices, and other components of a traditional computing device; an electronic communication device such as a router, switch, etc. achieve desired system performance using a combination of electronic information storage systems (such as network attached storage (NAS) and storage area networks (SAN)) and computer software (i.e., instructions that cause a computing device to function in a specific way) It can be achieved.

Additionally, the processor of the computing device may include hardware components such as a Micro Processing Unit (MPU) or Central Processing Unit (CPU), cache memory, and data bus. Additionally, the computing device may further include an operating system and a software component of an application that performs a specific purpose.

However, this does not exclude the case where the computing device includes an integrated processor in which a medium, processor, and memory for implementing the present invention are integrated.

The content management system 1000 configured in this way issues an NFT in accordance with the NFT issuance request received from the content owner terminal, and refers to the copyright property use application menu selection information received from the content user terminal to provide original digital content or duplicate digital content. A method of providing a token for access will be described with reference to FIGS. 3 to 5.

For reference, digital assets, unlike precious metals, can be copied infinitely and have the characteristic of making it impossible to distinguish between originals and copies. In addition, looking at the process by which NFTs for digital assets are created, they are not created after screening according to strict standards, but when a digital asset is uploaded, an NFT for the digital asset is issued, so it is a digital asset in a specific blockchain network. Even if an NFT for the original is issued, the NFT is issued by a third party who does not have ownership of the original digital asset for a digital asset replicated on a blockchain network other than a specific blockchain network, making it impossible for any NFT to correspond to the original digital asset. It is difficult to distinguish whether it is an NFT, and as a result, a situation may arise where it is difficult to protect the copyright of the original digital asset.

Therefore, through the process described below for NFT, it is possible to apply for and approve the use of copyright rights for a digital asset while having the URL of the original digital asset that is not disclosed to the content user, and through approval, a copy of the digital asset can be provided to the content user. Alternatively, you can prevent the above situation from occurring and preserve the value of the original digital asset by providing a token that can access the original.

Figure 3 schematically shows a process in which a content management system that manages digital content of NFT according to an embodiment of the present invention issues NFT in response to an NFT issuance request.

With reference to Figure 3, the process of issuing NFT for digital content according to an embodiment of the present invention will be described in detail as follows.

First, the content management system 1000 may obtain an NFT issuance request including original digital content and information about the original digital content from the content owner terminal 100 (S210).

As an example, the web/app service server 1100 of the content management system 1000 provides an NFT issuance service through a web or app installed on the content owner's content owner terminal 100, so that the content owner can use the content owner terminal 100. ), you can input the original digital content and information about the original digital content necessary for issuing the NFT, and when requesting the issuance of an NFT after inputting the original digital content and information about it, the web or installed on the content owner terminal 100 Through linking with the app, the web/app service server 1100 can obtain an NFT issuance request containing original digital content and information about it.

At this time, the content owner terminal 100 may use various computing devices such as PCs, tablets, mobile computers, PDAs/EDAs, mobile phones, smartphones, IOT devices, etc., but is not limited thereto.

Additionally, the information about the original digital content may include various information such as a description of the original digital content itself, a description of copyright property rights for the original digital content, copyright holder, publication date, and additional explanation of the original digital content.

For example, if the original digital content is a music file, information about the original digital content may include the artist name, album name, release date, etc. Additionally, in the case of CryptoKitty, which currently provides NFT services, a description of the cat, name, photo, and additional attributes may be included. Additionally, in the case of performance tickets, information about the original digital content may include performance date and seat information in addition to the ticket name and description. However, information about original digital content in the present invention is not limited to these examples and may include various information related to digital content related to NFT.

Next, the content management system 1000 inserts a watermark into the acquired original digital content to create display digital content (S220), and stores each of the original digital content and display digital content in the data storage system 2300. (S230).

In addition, the content management system 1000 may obtain original link information, which is access path information for the original digital content stored in the data storage system 2300, and display source link information, which is access path information for the display source digital content. (S240).

As an example, original digital content obtained from the content owner terminal 100 is transmitted to the data storage management server 1600 through the web/app service server 1100 of the content management system 1000, and the data storage management server 1600 ) can store the original digital content in the data storage system 2300. In addition, the data storage management server 1600 may insert a watermark into the original digital content to create the displayed digital content and then store the displayed digital content in the data storage system 2300. In addition, the data storage management server 1600 provides original link information, which is access information to the original digital content stored in the data storage system 2300, and display bone, which is access path information to the display bone digital content stored in the data storage system 2300. Link information can be obtained and managed.

At this time, Displaybone digital content is intended to prevent illegal copying of the original digital content for the issued NFT, by inserting confidential information such as copyright information into the original digital content, or inserting pictures or text into the original digital content. and various digital watermarks that allow information to be tracked.

In addition, the data storage system 2300 is a database, a file system, a CDN (Content Delivery Network) that stores cached content on an edge server at a Point-Of-Presence (POP) location close to the end user, thereby minimizing dash time, and a distributed It may include at least one of IPFS (Interplanetary File System), a peer-to-peer network for sharing and storing data in the file system, the content management system 1000, or another system linked to it or a drive device of another server. It is not limited to this.

Additionally, the content management system 1000 supports storing each of the original digital content and the displayed digital content in different data storage systems 2300, so that the original digital content and the displayed digital content can be managed separately.

Next, the content management system 1000 includes DisplayBorn digital content displayed in response to DisplayBorn link information, information on the original digital content, and a copyright rights use application menu for applying for copyright use of the original digital content. You can create copyright property use application link information, which is access path information for the copyright property use application page (S250).

As an example, the data storage management server 1600 of the content management system 1000 transmits display bone link information to the NFT issuing server 1400, and the NFT issuing server 1400 obtains it from the data storage management server 1600. Using the DisplayBone link information, DisplayBorn digital content displayed in response to the DisplayBorn link information, information on the original digital content, and a copyright property use application menu for applying for copyright use of the original digital content. You can create copyright property use application link information, which is access path information for the copyright property use application page. In contrast, the data storage management server 1600 of the content management system 1000 applies for the use of copyright rights for the DisplayBorn digital content displayed in response to the DisplayBorn link information, information on the original digital content, and the original digital content. It is possible to generate copyright property use application link information, which is access path information for the copyright property use application page including the copyright property use application menu.

Here, an example of a copyright property use application page that can be confirmed through copyright property use application link information will be described in FIG. 5.

Next, the content management system 1000 may generate an NFT issuance transaction including NFT asset information and copyright property use application link information (S260).

As an example, the NFT issuance server 1400 of the content management system 1000 may generate an NFT issuance transaction that includes NFT asset information and link information for applying for copyright property use as NFT metadata.

At this time, NFT asset information may include various information related to NFT, such as token ID, smart contract address, NFT issuer information, NFT blockchain network information, content metadata information, etc. Additionally, NFT asset information may include various verification information such as timestamps and signature values to verify the validity of the NFT.

Afterwards, the content management system 1000 broadcasts the NFT issuance transaction to the NFT blockchain network 2100 (S270) and the NFT issuance transaction is transmitted to the NFT blockchain by distributed agreement of the nodes constituting the NFT blockchain network 2100. NFTs for original digital content can be issued by registering them in the distributed ledger of the network 2100 (S280).

As an example, the NFT issuance server 1400 of the content management system 1000 broadcasts an NFT issuance transaction to the NFT blockchain network 2100 to issue an NFT by distributed agreement of the nodes constituting the NFT blockchain network 2100. It is possible to support the issuance of NFTs for original digital content by ensuring that transactions are registered in the distributed ledger of the NFT blockchain network (2100). In addition, when an NFT is issued, the NFT issuing server 1400 obtains the NFT issuance result information from the NFT blockchain network 2100 and transmits it to the web/app service server 1100, so that the content owner can send it to the content owner terminal 100. You can check NFT issuance result information through the installed web or app.

At this time, the issued NFT is not the original digital content, but various digital watermarks that insert secret information such as copyright information into the original digital content, or insert pictures or text into the original digital content, allowing the original source and information to be traced.
