Description

Method and system for providing content using a non-funcible token of certificate to prove the right to view the content.

The present disclosure relates to a method and system for providing content using a certificate NFT proving the right to view content.

A non-fungible token (NFT) is a virtual token that uses blockchain technology to prove ownership of a digital asset. These NFTs possess uniqueness and cannot be duplicated, making them widely used for their scarcity value.

The creator of a digital asset is assigned a unique identification code through the minting process for creating an NFT, allowing all participants in the blockchain network to verify the ownership of the digital asset.

NFTs are not stored in the account or storage of the actual owner, but rather exist on the blockchain network. NFT transactions are made by sending a transaction to the blockchain network to change the owner of the digital asset.

The transaction details are created as blocks through mutual verification by the network and linked to the chain. Transactions have a unique ID, a hash value, which is used to verify the delivery of the NFT and the validity of the transaction information. Once verification is complete, ownership is transferred to the buyer, and since all transaction details and information are shared across the network, falsification is impossible.

These NFT characteristics have made digital assets easily tradeable. Currently, assets with artistic value, such as games, music, and artwork, are primarily created and traded as NFTs. In other words, NFT technology contributes to the revitalization of the market economy by granting value to digital files of various real-world assets, digital art, and intellectual property rights.

Meanwhile, in the media platform market that provides streaming and download services for music and videos, the adoption of NFTs is still minimal, and as a result, there are limitations in terms of marketability and security.

For example, in the case of streaming services, there are no restrictions on content consumption, so it does not induce a desire for ownership, and since it can be viewed or enjoyed freely, it is easy to copy, which often leads to infringement of copyright holders' rights.

Even media files provided through download services are not assigned a unique identification code, making it difficult to consider them fully owned by the user. Consequently, reselling the media files prevents generating additional revenue. Furthermore, if certain restrictions, such as a limited time period, are imposed, the files become unplayable. Furthermore, media files provided to users are easily copied, making unauthorized distribution difficult to protect copyright.

Furthermore, even if NFT technology is applied to the media platform market and the ownership of content changes, the content remains publicly available, allowing anyone to access it, thus significantly reducing its scarcity. Furthermore, if this is not taken into account and exposed on the platform, its economic value will significantly decline, defeating the purpose of the content. Furthermore, since the change in content ownership is merely a change in ownership, the persistent problems of piracy and downloading remain difficult to resolve. These factors hinder the effectiveness of NFT production for content.

The present disclosure aims to address the problems of the prior art described above, and improve the limitations of the existing media platform market by issuing NFTs that prove the right to stream or download content and providing content to users whose ownership thereof has been verified.

However, the technical problems to be solved by the embodiments of the present disclosure are not limited to the technical problems described above, and other technical problems may exist.

The term "smart contract," as used herein, refers to an electronic contract existing on a blockchain, designed to automatically execute (self-execute) when agreed-upon terms and conditions are met. The contract's contents are written as smart contract source code and transmitted to the blockchain network. Network participants then verify its validity. Upon completion of verification, a block containing the smart contract is created and distributed.

Below, it is explained that the NFT market server or content server creates and transmits a smart contract or transaction, but this is only an agent for processing at the request of the creator terminal and user terminal, and in reality, the subjects of execution on the blockchain network (150) should be interpreted as the creator and user.

FIG. 1 is a structural diagram of an NFT proof-based content provision system according to one embodiment of the present disclosure.

Referring to FIG. 1, the system includes an NFT market server (110), a content server (120), a creator terminal (130), a user terminal (140), and a blockchain network (150).

According to one embodiment, a blockchain network (150) is a decentralized distributed network that mutually verifies and processes various smart contracts and transactions associated with NFT issuance and NFT transactions through a proof-of-work process. Participants (nodes) of the blockchain network (150) share all processing results. The blockchain network (150) is typically a public blockchain, but may also include a private blockchain. In addition, the blockchain network (150) may include various types, such as an Ethernet network, a smart chain network, a Solana network, an Avalanche network, and a Klaytn network, but is not limited thereto.

According to one embodiment, a creator terminal (130) is a terminal in which the creator is the main entity and may include memory (not shown), a processor (not shown), and a communication module (not shown). The communication module performs data communication with the NFT market server (110) and the content server (120) under the control of the processor. Furthermore, the creator terminal (130) is connected to the blockchain network (150) through the communication module and participates as a node.

According to one embodiment, the memory may store an NFT market place program (or application) provided from an NFT market server (110). Additionally, a content place program provided from a content server (120) may be stored.

The processor executes a series of operations to provide creators with a user interface for creating and trading certificate NFTs, registering and providing content, by executing programs stored in memory.

According to one embodiment, the creator terminal (130) can create a first blockchain wallet through a wallet creation user interface distributed by the blockchain network (150). The creator terminal (130) transmits a transaction for creating the first blockchain wallet to the blockchain network (150), and when mutual verification is completed, the first blockchain wallet is created and exists on the blockchain network (150). The first blockchain wallet stores cryptocurrency, NFT, personal identification, etc., and stores content previously created by the creator terminal (130).

In one embodiment, the first blockchain wallet may include a first blockchain account and a first contract account. The creator terminal (130) can create a desired transaction and transmit it to the blockchain network (150) by signing it using a unique private key via the first blockchain account. Accordingly, the status of the first blockchain account may be changed, and the number of successfully transmitted transactions, the cryptocurrency balance, and NFT information may be recorded. Meanwhile, the creator terminal (130) may use the private key to generate a public key, and the address of the first blockchain wallet may be set based on the public key.

The first contract account can store the number of transactions transmitted, the cryptocurrency balance, NFT information, as well as the status information of the smart contract and the code for executing it. This information is implemented as a hash value of a certain length and can be used as an address to locate the location where the information is actually stored. Specifically, the code hash value identifies the location where the executable code is stored, and the storage hash value indicates the actual location where the contract's status information will be implemented upon code execution.

According to one embodiment, a user terminal (140) is a terminal operated by an Internet user who wishes to consume the creator's content. The terminal may include memory (not shown), a processor (not shown), and a communication module (not shown). Under the control of the processor, the communication module performs data communication with the NFT market server (110) and the content server (120). Furthermore, the user terminal (130) is connected to the blockchain network (150) through the communication module and participates as a node.

According to one embodiment, the memory may store an NFT market place program (or application) provided from an NFT market server (110). Additionally, a content place program provided from a content server (120) may be stored.

The processor executes a program stored in memory to process a series of operations to provide the user with a user interface for NFT transactions and content viewing.

According to one embodiment, a user terminal (140) can create a second blockchain wallet through a wallet creation user interface distributed by a blockchain network (150). The user terminal (140) transmits a transaction for creating a second blockchain wallet to the blockchain network (150), and when mutual verification is completed, a second blockchain wallet is created and exists on the blockchain network (150). The second blockchain wallet stores cryptocurrency balance, NFT information, personal identification, etc.

In one embodiment, the second blockchain wallet may include a second blockchain account and a second contract account. The user terminal (140) can create a desired transaction and transmit it to the blockchain network (150) by signing it using a unique private key via the second blockchain account. Accordingly, the status of the second blockchain account may be changed, and the number of successfully transmitted transactions, the cryptocurrency balance, and NFT information may be recorded. Meanwhile, the user terminal (140) may use the private key to create a public key, and the address of the second blockchain wallet may be set based on the public key.

The second contract account can store the number of transactions transmitted, the cryptocurrency balance, NFT information, as well as the status information of the smart contract and the code for executing it. This information is implemented as a hash value of a certain length and can be used as an address to locate the actual location where the information is stored. Specifically, the code hash value identifies the location where the executable code is stored, and the storage hash value indicates the actual location where the contract's status information will be implemented upon code execution.

Meanwhile, the "terminal" in this specification may be implemented as a computer or portable terminal that can connect to a server or other terminal via a network. Here, the computer may include, for example, a notebook, desktop, laptop, VR HMD (e.g., HTC VIVE, Oculus Rift, GearVR, DayDream, PSVR, etc.) equipped with a web browser. Here, the VR HMD includes all of the stand-alone models (e.g., Deepon, PICO, etc.) that are implemented independently for PC (e.g., HTC VIVE, Oculus Rift, FOVE, Deepon, etc.), mobile (e.g., GearVR, DayDream, Storm Magic, Google Cardboard, etc.), and console (PSVR). A portable terminal is, for example, a wireless communication device that ensures portability and mobility, and may include not only a smart phone, a tablet PC, and a wearable device, but also various devices equipped with communication modules such as Bluetooth (BLE, Bluetooth Low Energy), NFC, RFID, ultrasonic, infrared, WiFi, and LiFi. In addition, a "network" refers to a connection structure that enables information exchange between each node, such as terminals and servers, and includes a local area network (LAN), a wide area network (WAN), the Internet (WWW: World Wide Web), wired and wireless data communication networks, telephone networks, wired and wireless television communication networks, and blockchain networks. Examples of wireless data communication networks include, but are not limited to, 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), Wi-Fi, Bluetooth, infrared, ultrasonic, visible light communication (VLC), LiFi, etc.

Referring to FIG. 2, according to one embodiment, an NFT market server (110) may be configured to include a memory (210) storing a program for processing NFT creation and transactions, and a processor (220) executing the program. Additionally, the server may include a communication module (230) for processing data communication with a creator terminal (130) and a user terminal (140), and may be connected to a blockchain network (150) via the communication module (230).

The processor (220) can perform various functions according to the execution of a program stored in the memory (210). Depending on each function, the components included in the processor (220) can be represented as a member management unit (310), an NFT issuance unit (320), and an NFT transaction unit (330), and each component can be further subdivided into sub-components according to the specified function.

FIG. 3 is a block diagram showing a detailed structure of a processor of an NFT market server according to one embodiment of the present disclosure.

According to one embodiment, the member management unit (310) is responsible for managing creators and users who have registered on the NFT marketplace platform. Specifically, the member management unit (310) receives a predetermined fee (e.g., cryptocurrency) from the creator terminal (130) requesting membership and creates a creator wallet while registering the corresponding creator. The creator wallet can be applied as the creator's identification information on the NFT marketplace server (110) and is configured to be linked to the first blockchain wallet, thereby storing the creator's content. Thereafter, the member management unit (310) stores the certificate NFT of the issued content in the creator wallet. When the certificate NFT is depleted through a transaction, the member management unit updates the type and number of remaining certificate NFTs and stores them in the creator wallet. In other words, the creator can check the status information of the certificate NFT, such as which certificate NFTs have been issued, how many certificate NFTs remain, and how many certificate NFTs have been traded, through the creator wallet.

The member management unit (310) receives a predetermined fee (e.g., cryptocurrency) from the user terminal (140) requesting membership and creates a user wallet while registering the user. The user wallet can be applied as the user's identification information on the NFT market server (110) and is configured to be linked with a second blockchain wallet. Thereafter, at the request of the user terminal (140), the member management unit (310) stores the certificate NFT for which the transaction was completed and the proof of ownership in the user wallet. Furthermore, if the certificate NFT is depleted due to the sale of the certificate NFT to a third party, the type and number of remaining certificate NFTs are updated and stored in the user wallet. In other words, the user can check the status of his/her assets, such as the type and number of certificate NFTs purchased and the cryptocurrency balance, through the user wallet.

According to one embodiment, the NFT issuing unit (320) receives a request for minting a certificate NFT from a creator terminal (130) and, in response, processes the issuance of a certificate NFT proving the right to view content. Specifically, the NFT issuing unit (320) may receive copyright information of the certificate from the creator terminal (130). The copyright information may include at least one of video, image, text, and audio. In addition, the NFT issuing unit (320) generates a URL where the corresponding copyright information is exposed and sets it as an NFT address. In addition, the NFT issuing unit (320) receives the number of certificate NFTs to be issued from the creator terminal (130). The NFT issuing unit (320) generates a smart contract for issuing the certificate NFT in the number of issues and transmits it to the blockchain network (150). When a preset minting fee is received from the creator terminal (130), the NFT issuing unit (320) generates a transaction for executing the code within the smart contract to issue a certificate NFT and transmits it to the blockchain network (150). When the transmitted transaction is implemented as a block through mutual verification, the number of certificate NFTs issued is equal to the number of issued certificate NFTs, and the NFT issuing unit (320) stores the issued certificate NFTs in the creator wallet.

According to one embodiment, the NFT transaction unit (330) processes a transaction of a certificate NFT between a creator and a user. The NFT transaction unit (330) receives a transaction request for a certificate NFT along with a price for the certificate NFT from a user terminal (140). The NFT transaction unit (330) generates a transaction corresponding to the transaction request and transmits it to the blockchain network (150). When the transmitted transaction is implemented as a block through mutual verification, the ownership of the certificate NFT is transferred to the user, and the NFT transaction unit (330) stores the traded certificate NFT in the user's wallet and reflects the price (cryptocurrency) of the received NFT in the creator's wallet.

Referring to FIG. 4, a content server (120) according to one embodiment may be configured to include a memory (410) storing a program for providing content registration and viewing services, and a processor (420) for executing the program. Additionally, the content server may include a communication module (430) for processing data communication with a creator terminal (130) and a user terminal (140), and may be connected to a blockchain network (150) via the communication module (430).

The processor (420) can perform various functions according to the execution of a program stored in the memory (410). Depending on each function, the components included in the processor (420) can be represented as a member management unit (510), a content registration unit (520), and a content provision unit (530), and each component can be further subdivided into sub-components according to the specified function.

FIG. 5 is a block diagram showing a detailed structure of a processor of a content server according to one embodiment of the present disclosure.

In one embodiment, the member management unit (510) is responsible for managing creators and users who have registered with the content place platform. Specifically, the member management unit (510) receives a membership request from a creator terminal (130) and creates a creator account in response. The creator account can be applied as the creator's identification information on the content server (120) and is configured to be linked to a first blockchain wallet, thereby storing the creator's content. Furthermore, the member management unit (510) receives a membership request from a user terminal (140) and creates a user account in response. The user account can be applied as the user's identification information on the content server (120) and is configured to be linked to a second blockchain wallet. Furthermore, the user account is configured to be linked to a user wallet, thereby sharing a certificate NFT present in the user wallet with the user account.

According to one embodiment, the content registration unit (520) registers content in a creator account on the platform in response to a registration request from a creator terminal (130) and exposes the content to users who have signed up for the platform.

In one embodiment, the content provider (530) receives a content viewing request from a user terminal (140) and, in response, verifies whether a certificate NFT for the corresponding content exists in the user account. If so, the content provider (530) determines that the user has been granted access to the content and provides the content to the user terminal (140).

Hereinafter, an embodiment of a content provision method based on NFT proof according to the present disclosure will be described using FIGS. 6 and 7, with any redundant descriptions replaced with the aforementioned content. FIGS. 6 and 7 are flowcharts illustrating an operation of a content provision method based on NFT proof according to an embodiment of the present disclosure.

First, the NFT market server (110), content server (120), creator terminal (130), and user terminal (140) are interconnected to a preset blockchain network (150).

In step 610, the creator terminal (130) creates a first blockchain wallet. Furthermore, the creator terminal (130) distributes the previously produced content to the blockchain network (150). When a unique hash value is generated through proof-of-work, a block containing information about the content is created and linked to the chain. Accordingly, the content is stored via the first blockchain wallet, and all participants in the blockchain network (150) recognize that the creator is the creator and owner of the content.

In step 612, the creator terminal (130) requests a subscription from the content server (120), and the content server (120) creates a creator account in response. The created creator account is configured to be linked to the first blockchain wallet, and thus, the creator's content is stored in the creator account.

In step 614, the content server (120) extracts content stored in the creator account and registers it on the content place platform in response to a content registration request from the creator terminal (130). This allows users registered with the content server (120) to recognize that the content has been registered. Furthermore, when registering content, the content server (120) may additionally display information indicating that a certificate NFT is required in the content display area within the platform. Accordingly, users are made aware that they must access the NFT market server (110) to view the content.

In step 616, the creator terminal (130) requests registration from the NFT market server (110), and the NFT market server (110) generates a creator wallet in response. The generated creator wallet does not exist on the distributed network (150) but is managed by the NFT market server (110), but is configured to be linked to the first blockchain wallet. Therefore, the creator's content is stored in the creator wallet, and information about the content is displayed, allowing the creator to easily check it. In other words, the creator wallet may be a user interface designed to address the difficulty faced by general internet users, not experts, in identifying their assets or transaction history through an actual blockchain wallet.

In step 618, the creator terminal (130) requests the NFT market server (110) to mint a certificate NFT for content stored in the creator wallet. In response, the NFT market server (110) processes the process for issuing the certificate NFT.

In one embodiment, a certificate NFT may include copyright information indicating the bibliographic details of the content. The copyright information may include at least one of video, image, text, and audio. Furthermore, the copyright information is created by the creator and may include, but is not limited to, at least one of the following objects: the title, type, identification mark, identification number, summary, access rights, creator identifier, copyright notice, and copy protection flag. Furthermore, a certificate NFT may be issued in multiples. Each issued certificate NFT is unique due to the characteristics of the NFT, and unlike typical cryptocurrencies or gift certificates, it is assigned unique identification information. Therefore, ownership of each certificate NFT will vary depending on the user who transacts with it. Unlike existing streaming or download services, it is provided to users in a limited number of issued certificate NFTs, thereby ensuring scarcity value.

In one embodiment, the creator terminal (130) can set the price of the certificate NFT along with the minting request. For example, the creator terminal (130) can select one of the following methods: specifying a price, bidding, or bundled sales. In the case of bidding, the price may increase or decrease depending on the creator's fame or the popularity of the content, contributing to additional revenue generation for the creator and enhancing competitiveness.

In step 620, when a certificate NFT is issued through mutual verification of the blockchain network (150), the certificate NFT and the content registered in the content server (120) are mapped by the creator terminal (130).

In step 622, the user terminal (140) creates a second blockchain wallet. The second blockchain wallet records the user's cryptocurrency balance, NFT information, and various transaction details.

In step 624, the user terminal (140) requests registration from the content server (120), and the content server (120) creates a user account in response. The created user account is configured to be linked to a second blockchain wallet, allowing the user to easily check their cryptocurrency balance, NFT information, and various transaction histories through the user account. Furthermore, the user can request access to or check the details of content viewed through the user account. Furthermore, since the user account is linked to the user wallet, the NFT certificate and proof information for which ownership has already been acquired are stored, allowing the user to easily check them.

In step 626, the user terminal (140) requests registration from the NFT market server (110), and the NFT market server (110) creates a user wallet in response. The created user wallet does not exist on the distributed network (150) but is managed by the NFT market server (110), but is configured to be linked to a second blockchain wallet. Accordingly, the user wallet stores and displays cryptocurrency balances, NFT information, and various transaction histories. In other words, the user wallet may be a user interface designed to address the difficulty faced by non-expert internet users in identifying their assets or transaction histories through an actual blockchain wallet.

In step 628, the user terminal (140) requests a transaction for the certificate NFT to the NFT market server (110). For example, after the certificate NFT is issued, the NFT market server (110) may generate a smart contract containing the code "Transfer the certificate NFT when the transaction price is paid" and transmit it to the blockchain network (150). Nodes, including the user terminal (140) within the network (150), review the smart contract and agree to create a block. Once this verification is complete, a block containing the smart contract is generated and distributed, and each node adds the block to its own chain. When the user terminal (140) requests a transaction, this is considered a signature for invoking the smart contract and executing the code. Accordingly, the NFT market server (110) generates a transaction to execute the code and change the state and transmits it to the blockchain network (150). Once the transaction is verified, the code is executed, changing the state of the first blockchain wallet by the amount of the transaction, and setting the ownership of the certificate NFT to the address of the second blockchain wallet.

In this way, when ownership is transferred, the NFT market server (110) stores the corresponding certificate NFT in the user's wallet. This may simply mean that the corresponding proof information and copyright information for the NFT are stored. In this way, users who wish to stream or download specific content must secure access to the content through the certificate NFT. This fact is shared with all participants on the network (150), making falsification impossible and preventing future copyright infringement of the content.

In step 630, the user terminal (140) requests the content server (120) to view the content, and the content server (120) responds by checking whether the user has the right to view the content. That is, the content server (120) searches for the user account and checks for the presence of a certificate NFT. This may be a different expression, but it can also mean checking whether the ownership of the certificate NFT is set to a second blockchain address. If the certificate NFT is confirmed, the content server (120) determines that the user is a legitimate user who can view the content and provides the content to the user terminal (140).

Hereinafter, various applied embodiments of the present disclosure will be introduced using FIGS. 8 through 14. First, the process of issuing a certificate NFT will be described in more detail with reference to FIG. 8. FIG. 8 is a flowchart illustrating the process of issuing a certificate NFT according to one embodiment of the present disclosure.

In step 810, the creator terminal (130) uploads the copyright information of the certificate indicating the content's viewing authority to the NFT market server (110) and sets the number of certificate NFTs issued. The format in which the viewing authority is indicated may vary, such as an authorization code or authorization mark, and is not specifically limited by the present disclosure. Furthermore, the copyright information of the certificate may include bibliographic information about the content as described above, and may be implemented differently for each issued number. For example, each copyright information may be created by the creator to include a different authorization code.

In step 820, the NFT market server (110) may distribute a smart contract for issuing a certificate NFT in the same number of issues. For example, the NFT market server (110) may obtain a code that says, "If the minting fee for the certificate NFT is transferred, a certificate NFT is issued," and may create a smart contract including the code in the same number of issues and transmit the smart contract to the blockchain network (150). Participants within the network (150) review the smart contract and agree to create a block. Once this verification is completed, a block containing the smart contract is created and distributed, and each participant adds the block to their own chain, thereby sharing the smart contract.

In step 830, the NFT market server (110) may generate a URL where the copyright information uploaded in step 810 is displayed. Since NFTs require the disclosure of media information (metadata) of digital assets, and creators upload copyright information through the NFT market place, a process for processing this information is necessary. Accordingly, the NFT market server (110), which oversees the NFT market place process, generates a unique URL where copyright information is displayed and sets this as the NFT address. Meanwhile, if the URL where copyright information is displayed is input by the creator terminal (130) in step 810, step 830 may be omitted.

In step 840, when the creator terminal (130) requests minting by sending a minting fee to the NFT market server, this is considered a signature for invoking a smart contract and executing the code. Accordingly, the NFT market server (110) generates a transaction for executing the code for issuing the certificate NFT, corresponding to the number of issuances, and transmits it to the blockchain network (150). At this time, the issuance code may be actually stored in the first contract account of the first blockchain wallet.

At step 850, when the transaction's mutual verification is completed by the blockchain network (150), a block is generated and combined into the chain of all participants, thereby issuing the same number of certificate NFTs as the issued number and existing on the network (150). The owner and creator of each certificate NFT is set to the address (creator) of the first blockchain wallet, and each certificate NFT may include owner information, creator information, an NFT address, and unique identification information. In addition, the first contract account may be created with information such as the number of certificate NFTs issued and a hash value indicating the creator as the owner, so that status information can be changed.

In one embodiment, a creator may limit the viewing period to ensure the value and rarity of the content. The operation of the system related to this will be described below using Figure 9. Figure 9 is a flowchart illustrating a process for a limited viewing period of content according to one embodiment of the present disclosure.

In step 910, the creator terminal (130) can set a content viewing period through the user interface of the NFT marketplace. That is, the content marketplace can limit the period during which users can stream or download content.

In step 920, when the viewing period is received, the NFT market server (110) may deploy a smart contract for the return of ownership of the certificate NFT. For example, the NFT market server (110) may obtain a code that states, "Ownership of the certificate NFT is set to the address of the first blockchain wallet when the viewing period expires," and generate a smart contract containing the code and transmit it to the blockchain network (150). Participants within the network (150) review the smart contract and agree to create a block. Upon completion of this verification, a block containing the smart contract is generated and distributed, and each participant adds the block to their own chain, thereby sharing the smart contract.

At step 930, after the certificate NFT transaction is processed and ownership is set to the address of the second blockchain wallet, and the viewing period has elapsed, the contract conditions are satisfied and the smart contract code is executed.

At step 940, once the transaction verification for code execution is completed, ownership of the certificate NFT is set to the first blockchain address, and the certificate NFT stored in the user account and wallet is deleted. The NFT market server (110) checks the user wallet and deletes any remaining copyright information and proof information. The content server (120) also checks the user account and deletes any remaining copyright information and proof information.

In one embodiment, a user can specify a portion of the content they desire and have access to it. For example, a consumer may only want to collect a portion of a series or a specific character in a comic book. In such cases, granting exclusive access to the content can foster a sense of ownership and provide a customized collection. A related embodiment is described with reference to FIG. 10. FIG. 10 is a flowchart illustrating a process when options are set for content viewing according to one embodiment of the present disclosure.

In step 1010, the user terminal (140) can set option information for specific content in the NFT marketplace. The option information, which specifies only the portion desired by the user from the entire content, may include, but is not limited to, at least one of a specific playback section, character, scene, track, episode, season, and cover of the content. The NFT market server (110) receives the option information and provides it to the creator terminal (130) of the corresponding content, while requesting whether to mint the detailed certificate NFT. Here, the detailed certificate NFT is a non-fungible token that proves the right to view the content for which the optional information is set and notifies all participants in the network (150) of the ownership thereof.

In step 1020, if the creator terminal (130) requests minting of a detailed certificate NFT, the NFT market server (110) may deploy a smart contract for issuing the detailed certificate NFT. For example, the NFT market server (110) may obtain a code that reads, "If the minting fee for the detailed certificate NFT is transferred, a detailed certificate NFT is issued," create a smart contract containing the code, and transmit it to the blockchain network (150). If the smart contract is verified by the network (150), the detailed certificate NFT is issued, and ownership thereof is set to the address of the first blockchain wallet.

Thereafter, the NFT market server (110) processes a transaction of a certificate NFT based on a transaction request for a certificate NFT from a user terminal (140). A detailed description thereof will be replaced with the description of the certificate NFT transaction described above. Once the transaction is processed, the status of the first blockchain wallet changes based on the consideration, ownership of the certificate NFT is set to the address of the second blockchain wallet, and the certificate NFT is stored in the user wallet.

In step 1030, when ownership of the detailed certificate NFT is transferred, the NFT market server (110) deploys a smart contract for providing a portion of the content according to the option. For example, a code that states, "When a request to view content is made, a portion of the content according to the option information is extracted and provided to the terminal that requested the view" can be obtained, and a smart contract containing this code can be created and transmitted to the blockchain network (150).

In step 1040, if the user terminal (140) requests to view the content, the conditions of the smart contract are satisfied. That is, the user's request to view the content is considered a signature for invoking the smart contract and executing the code. Accordingly, the content server (120) transmits the code execution transaction to the blockchain network (150). At this time, the content server (120) merely acts as a node on behalf of the user terminal (140), and the code may actually be stored in the second contract account of the second blockchain wallet. Once the transaction is verified, the content server (120) extracts only the portion of the content that matches the optional information and provides it to the user terminal (140). For example, if the optional information is the intro of song A, the user has exclusive rights to stream or download the intro of song A. Alternatively, if the option information is the role of "Hong Gil-dong" in a B-movie, the user will be able to watch the part where "Hong Gil-dong" appears in the B-movie and will have exclusive rights to streaming or downloading that part.

In one embodiment, a user may have difficulty finding specific content, even though they have been issued a certificate NFT to view it, due to the sheer volume of content on the content platform. In this regard, the present disclosure discloses an embodiment of automatic content provisioning, as illustrated with FIG. 11. FIG. 11 is a flowchart illustrating the automatic content provision process according to one embodiment of the present disclosure.

In step 1110, when a transaction of a certificate NFT is completed, the NFT market server (110) generates proof information for the certificate NFT. The proof information serves to prove ownership of the certificate NFT and is data that adds visibility to the certificate NFT that actually exists on the blockchain network (150). It may be text, media, or a combination thereof, but its form is not particularly limited. The NFT market server (110) stores the generated proof information in the user wallet, and since the user wallet and the user account are linked, the proof information is also shared with the user account.

In step 1120, the content server (120) may deploy a smart contract for automatic content provision. For example, the code "Content will be provided to the user terminal when the user account's credentials are verified" may be obtained, a smart contract containing this code may be created, and transmitted to the blockchain network (150).

In step 1130, when a user terminal (140) accesses the content server (120) and the user wallet is activated, the content server (120) can identify it and query the user wallet. If the presence of proof information is confirmed through the query, the smart contract code is executed upon fulfillment of the contract conditions.

In step 1140, even if there is no viewing request from the user terminal (140), the content server (120) provides the corresponding content to the user terminal (140) by executing the code, and accordingly, streaming or downloading proceeds automatically.

In one embodiment, unlike conventional methods, users possess unique viewing rights, so reselling them to third parties does not infringe ownership or copyright, thereby providing an opportunity to generate additional revenue. In this regard, the present disclosure discloses an embodiment of the certificate NFT sales process, which is illustrated using FIG. 12. FIG. 12 is a flowchart illustrating the certificate NFT sales process according to one embodiment of the present disclosure.

At step 1210, a user who owns a certificate NFT can request the sale of the certificate NFT to a third party through the NFT market server (110).

In step 1220, the NFT market server (110) may deploy a smart contract for the sale of a certificate NFT in response to a sales request from a user terminal (130). For example, the NFT market server (110) may obtain a code that reads, "If the transaction price is paid, transfer the certificate NFT," create a smart contract containing the code, and transmit it to the blockchain network (150). Meanwhile, the actual subject of the contract may be the user, and the code may be stored in a second contract account.

That is, the sales request of the user terminal (130) is implemented as an operation in which the NFT market server (110) creates a transaction for the sale of the certificate NFT and transmits it to the blockchain network (150). Accordingly, the transaction is shared with all participants (user terminals) of the network (150), and when the transaction verification is completed and a block is created, the block is connected to the chain of all participants.

At step 1230, if a specific user terminal among all participants requests to purchase a certificate NFT by paying a fee to the NFT market server (110), a transaction for code execution is distributed upon fulfillment of the contract terms. That is, the purchase request is considered a signature for invoking a smart contract and executing the code. Accordingly, the NFT market server (110) generates a transaction for the purchase of the certificate NFT and transmits it to the blockchain network (150).

At step 1240, once the mutual verification of the purchase transaction is complete, ownership of the Certificate NFT is established in the purchasing user's blockchain wallet address. This transfers ownership, and the Certificate NFT, copyright information, and proof information stored in the seller's user account and the user's wallet are deleted.

Meanwhile, we have introduced an example where creators retain ownership of their content while only selling access to it. However, if necessary, such as when a quick cash flow is needed, creators can transfer ownership of both the content itself and the access to it, generating double revenue. In this regard, the present disclosure discloses an embodiment of a content NFT, which will be explained using FIG. 13. FIG. 13 is a flowchart illustrating the process of creating and selling a content NFT according to one embodiment of the present disclosure.

In step 1310, the creator terminal (130) may request the NFT market server (110) to mint and sell content NFTs for the purpose of transferring ownership of the content. Upon receiving this, the NFT market server (110) identifies the URL where the content is exposed by the content server (120) and sets it as the NFT address to secure the required NFT address.

In step 1320, the NFT market server (110) processes the issuance of a content NFT in response to the minting request. For example, the NFT market server (110) may obtain a code that states, "If the minting fee for the content NFT is transferred, a content NFT is issued," create a smart contract containing the code, and transmit it to the blockchain network (150). Participants within the network (150) review the smart contract and agree to create a block. Once this verification is complete, a block containing the smart contract is created and distributed, and each participant shares the smart contract by adding the block to their own chain.

When a creator terminal (130) requests minting by sending a minting fee to the NFT market server, this is considered a signature for calling a smart contract and executing a code, and accordingly, the NFT market server (110) transmits a transaction for executing the code for issuing a content NFT to the blockchain network (150). When mutual verification of the transaction is complete, the owner information and creator information of the content NFT are set corresponding to the address of the first blockchain wallet, and a content NFT including the NFT address, owner information, creator information, and unique identification information is issued.

In step 1330, after the content NFT is issued, the NFT market server (110) may deploy a smart contract for the sale of the content NFT in response to a sales request. For example, the NFT market server (110) may obtain a code that reads, "Content NFT will be transferred when the transaction price is paid," create a smart contract containing the code, and transmit it to the blockchain network (150). Meanwhile, the actual contract subject may be the creator, and the code may be stored in the first contract account.

That is, the sales request of the creator terminal (130) is implemented as an operation in which the NFT market server (110) creates a transaction for the sale of content NFT and transmits it to the blockchain network (150). Accordingly, the transaction is shared with all participants (user terminals) of the network (150), and when the transaction verification is completed and a block is created, the block is connected to the chain of all participants.

At step 1340, if a specific user terminal among all participants requests to purchase a content NFT by paying a fee to the NFT market server (110), a transaction for code execution is distributed upon fulfillment of the contract terms. That is, the purchase request is considered a signature for invoking a smart contract and executing the code. Accordingly, the NFT market server (110) generates a transaction for the purchase of the content NFT and transmits it to the blockchain network (150).

At step 1350, once the mutual verification of the purchase transaction is complete, ownership of the content NFT is set to the address of the purchasing user's blockchain wallet. This means that ownership of the content is transferred, and the content stored in the creator account and creator wallet is deleted. However, even if the ownership of the content NFT changes, the ownership of the previously issued certificate NFT is not affected. If the creator retains the previously issued certificate NFT, it means that they legitimately obtained it by paying a fee. If the user retains the certificate NFT, it means that they acquired ownership by paying a fee. Therefore, the creator can access the content with the remaining certificate NFT and can also sell it to a third party.

In one embodiment, a creator's content may also be available offline. For example, in the case of a play or musical, the content may be provided through both a theater viewing service and a streaming service that is filmed in real time. In offline performances, the typical method is to reserve or issue physical tickets. However, if users who purchase a certificate NFT for the same content want to view the performance, this can lead to double costs. This disclosure discloses an embodiment that addresses this issue, and will be described with reference to FIG. 14. FIG. 14 is a conceptual diagram illustrating an offline linkage service according to one embodiment of the disclosure.

First, if a creator's specific content is confirmed to be available offline, the content server (120) deploys a smart contract for ticket issuance to prevent duplication of costs. For example, the content server (120) obtains a code that states, "If a certificate NFT is identified, an admission ticket for the corresponding content will be issued," creates a smart contract containing this code, and transmits it to the blockchain network (150). The smart contract is mutually verified and shared with all nodes connected to the network (150).

An Internet of Things (IoT) device (1410) for issuing admission tickets may be placed at the entrance to the site. The IoT device (1410) may include a communication module (not shown), a sensor unit (1420), and a content recognizer (1430).

The communication module handles wireless communication with the content server (120). Accordingly, the IoT device (1410) can receive real-time information on content being processed at the location from the content server (120). The content information may include at least one of a title, type, identification mark, identification number, summary, viewing qualifications, creator identifier, and copyright notice. Furthermore, the IoT device (1410) is designed to be connected to a blockchain network (150) via the communication module and form a node. Accordingly, the IoT device (1410) can verify smart contracts and transactions distributed to the network (150), and can also transmit them.

The sensor unit (1420) can identify the certificate NFT displayed on the screen of the user terminal (140). Preferably, a camera is configured to identify the copyright information of the certificate NFT.

Even if the copyright information is identified by the sensor unit (1420), it must be determined what content the certificate NFT relates to. Accordingly, a content recognizer (1430) according to one embodiment can be constructed by image learning using a preset deep learning model. Specifically, the content server (120) randomly extracts some or all of the content stored in the database. The content server (120) verifies the NFT address for each extracted content and extracts the copyright information of the certificate NFT. The content server (120) sets the extracted copyright information as training data. As described above, the copyright information may include at least one object from among the title, type, identification mark, identification number, summary, viewing qualification, creator identifier, copyright notice, and copy prevention flag of the content. When the training data is input to the deep learning model, the content server (120) repeatedly trains the model so that the objects included in the training data are recognized. Accordingly, the content indicated by the copyright information can be determined by the recognized object. That is, the content server (120) can build a content recognizer (1430) that outputs corresponding content when the copyright information of a specific certificate NFT is input by repeating training and optimizing the algorithm of the deep learning model. In addition, in order to minimize the delay due to communication, the content server (120) transmits the built content recognizer (1430) to the IoT device (1410), and the IoT device (1410) stores it internally and utilizes the function on its own. Of course, the content recognizer (1430) may be pre-built into the IoT device (1410), and the content recognizer (1430) may be continuously updated by copyright information input in the actual field. Meanwhile, the deep learning model is preferably YOLO (You Only Look Once), which is specialized in image object recognition, but the CNN (Convolutional Neural Network) series can also be applied.

According to the above embodiment, the user's on-site entry proceeds as follows. The sensor unit (1420) senses the screen of the user terminal (140) to identify and store the work information (1440) of the certificate NFT. The work information (1440) is input into the content recognizer (1430), and the content (1450) corresponding to the certificate NFT is output. Accordingly, the certificate NFT of the content that the user is trying to view is identified by the IoT device (1410), and when the conditions of the smart contract are fulfilled and the code is executed, an admission ticket (1460) for the corresponding content is issued.

We have discussed various embodiments so far. Those skilled in the art will appreciate that the present invention can be implemented in modified forms without departing from its essential characteristics. Therefore, the disclosed embodiments should be considered illustrative rather than restrictive. The scope of the present invention is set forth in the claims, not the foregoing description, and all differences within the scope equivalent thereto should be construed as being encompassed by the present invention.
