Description

[Technical field]

[0001] The present invention relates to an NFT-based digital content management system and method, and more particularly to a system and method for converting digital content into various versions of NFT digital content, generating non-fungible tokens for each version, managing owners, and trading ownership information. [Background technology]

[0002] Various contents such as audio, images, and videos are digitized and distributed as digital contents. Such digital contents have the characteristic of being easily copied and shared. Due to such a characteristic, various methods for managing rights to digital contents are being researched.

[0003] Generally, a technology called DRM (Digital Rights Management) is a technology that manages playback rights for such digital content and allows only authorized users to use the digital content.

[0004] The prior art, Patent Document 1, “Content file distribution system and method using blockchain-based smart contract,” is a technology that uses blockchain technology to manage transactions for digital content and generate revenue using the digital content, and by combining blockchain with DRM, it enables more rational and secure digital content management.

[0005] Such DRM technology is a technology for managing the right to play the same content. Recently, non-fungible tokens (NFTs) have been used as a technology that allows not only playback rights but also ownership of the content itself to be safely managed. Non-fungible tokens issue tokens for a single piece of digital content that cannot be substituted for other tokens, and manage the ownership history of these tokens to identify the rightful owner of the digital content.

[0006] However, even with such non-fungible tokens, there can only be one owner for one piece of digital content, and there is no difference in terms of content playback between those who do not have the token, meaning that there is a limit to the revenue generation that can be achieved through this. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Korean Patent No. 10-2142259 Summary of the Invention [Problem to be solved by the invention]

[Figure 4] 1 is a flowchart showing a flow of a digital content management method according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the present invention, if it is determined that a detailed description of related known configurations or functions may obscure the gist of the present invention, the detailed description will be omitted. In addition, specific numerical values ​​in the description of the embodiments of the present invention are merely examples, and do not limit the scope of the invention.

[0024] The digital content management system according to the present invention may be configured to have a server configuration including a central processing unit (CPU) and memory, and connectable to other terminals via a communication network such as the Internet. However, the present invention is not limited by the configuration of the central processing unit and memory. Furthermore, the digital content management system according to the present invention may be physically configured as a single device, or may be embodied in a distributed form across multiple devices.

[0025] FIG. 1 is a block diagram showing the internal configuration of a digital content management system according to an embodiment of the present invention.

[0026] As shown in the figure, a digital content management system 101 according to an embodiment of the present invention may include a digital content information receiving unit 110, a digital content converting unit 120, a non-fungible token generating unit 130, a verifying unit 140, a digital content storing unit 150, a digital content playing unit 160, and a token trading unit 170. Each component may be a software module that operates physically within the same computer system, or may be configured to allow two or more physically separated computer systems to operate in conjunction with each other. Various embodiments including the same functions are within the scope of the present invention.

[0027] The digital content information receiving unit 110 receives digital content and the number of NFT contents to be generated based on the digital content. The present invention is characterized in that it converts various types of digital content into various versions and enables the owner to be identified for each version. The digital content may include sound sources, images, videos, etc., and in the case of sound sources, files such as MP3 files in which sound sources are compressed and stored, and in the case of images, files such as JPEG, GIF, PNG, etc. in which images are compressed and stored. In the case of a video, the file may be a compressed file such as MP4, AVI, etc. In addition, all content that can be stored in a digital form, such as a text document file, may be subject to the present invention.

[0028] The number of NFT contents to be generated received by the digital content information receiving unit 110 indicates the type of version into which the received digital content is converted, as described above. For example, if the number of NFT contents to be generated is 10, a total of 10 types of converted digital content can be generated. One of these can be the original digital content received, the rest can be content into which the original content is converted, and in some cases, all can be content stored differently from the original.

[0029] The digital content information receiving unit 110 can receive information regarding the digital content and the number of NFT contents to be generated from the owner who holds the original digital content, and the ownership of the converted NFT digital content generated thereby can also be primarily attributed to the owner of the original digital content.

[0030] The digital content conversion unit 120 converts the digital content and generates NFT digital contents equal to the number of the received NFT contents. As described above, the digital content is converted based on the information on the number of NFT contents received from the digital content information receiving unit 110. Here, various conversion methods can be applied depending on the type of digital content.

[0031] Here, the digital content conversion unit 120 converts the digital content so that the generated NFT digital contents have different qualities. A non-fungible token (NFT) technology allows ownership information of one digital content to be managed safely and transparently using a blockchain, but when using this technology, only one owner is possible for one digital content, and the number of circulating contents is limited, making it difficult to actively trade and generate profits from it.

[0032] Therefore, the digital content conversion unit 120 is characterized by converting one digital content into various versions so that each can be traded separately. In the case of multiple converted NFT digital contents, they are traded in the market at different prices by having slightly different qualities from the original. Here, it is preferable to convert so that at least a part of the original digital content can be used, even if there is a difference in quality.

[0033] For example, the digital content converted by the digital content conversion unit 120 may be a sound source content, and each of the generated NFT digital contents may be a content generated by shortening the playback time of the digital content. If an author wishes to manage the ownership of an unreleased sound source, if the original digital content has a sound source with the entire playback time, the first converted NFT digital content may be converted to a form in which the last 10 seconds are removed, and the second converted NFT digital content may be converted to a form in which the last 20 seconds are removed. In this way, by gradually adjusting the quality of the digital contents, it is possible to have relatively different values ​​and to have them traded at different prices in the market.

[0034] In some cases, a total of 3 minutes (180 seconds) of music can be divided into 10 versions, each with a playback time of 18 seconds. Based on information such as the price of ownership of the NFT digital content being traded, it is possible to understand what the public likes, leading to more active trading in order to own all the music, and maximizing revenue generation from ownership trading.

[0035] As another example, when the original digital content converted by the digital content conversion unit 120 is a video content, the NFT digital content can be generated by converting it to have various resolutions. As a result, the content having the original resolution can be relatively expensive, and as the resolution is lowered and the quality is degraded, it can be traded at a low price and can be traded in various ways in the market.

[0036] The non-fungible token generating unit 130 generates a non-fungible token for each of the generated NFT digital contents based on the blockchain. A non-fungible token (NFT) generates a token that can confirm the owner information for one piece of digital content using blockchain technology, stores information on the owner's change history in the token, and allows the owner to be clearly confirmed without centralized management due to the characteristics of distributed blockchain technology.

[0037] The non-fungible token generator 130 allows the owner of each converted NFT digital content to be managed separately and traded separately by generating a token for each converted NFT digital content. If 10 NFT digital contents are generated by conversion for one digital content, 10 non-fungible tokens (NFTs) are also generated.

[0038] The non-fungible token generator 130 can generate a token so that the owner of the original digital content is registered as the owner of the entire converted NFT digital content. This allows the original owner, such as the author of the digital content, to convert their digital content into various versions, own the ownership rights to each of them, and generate revenue by buying and selling some or all of them on the market.

[0039] When playing the generated NFT digital content, the verification unit 140 verifies the non-fungible token generated for the played NFT digital content. Non-fungible token (NFT) technology is a technology that allows the owner of digital content to be verified, but does not manage the playback authority of the corresponding digital content. Therefore, the digital content management system of the present invention can verify the owner of each content when playing digital content, and control the digital content to be played only by the owner, or to output the owner information of the digital content together when playing the digital content.

[0040] The verification unit 140 can verify the non-fungible token corresponding to the NFT digital content to be played and verify whether the final owner recorded in the token is the same as the user who requested the content to be played. To this end, the verification unit 140 can request information such as a password that can verify that the owner is the same as the owner recorded in the token from the user who requested the content to be played, and if the user is a subscriber to the content management system 101 of the present invention, the verification unit 140 can store information that can be verified by matching with the user of the token as user information, thereby enabling playback without needing to unnecessarily request verification information every time the user requests content playback.

[0041] The digital content storage unit 150 stores the digital content converted by the digital content conversion unit 120. Store the generated NFT digital content. As mentioned above, digital content can include various types of content, but is ultimately stored in the form of a digital file. Therefore, a digital file that stores information about the digital content can be stored on a recording medium, and the converted NFT digital content can be played upon request from a user. There are various ways to store NFT digital content, but it is preferable to apply content security technology that can prevent leakage of content.

[0042] The digital content playback unit 160 receives an NFT digital content playback command from a user, confirms the owner information of the non-fungible token of the NFT digital content corresponding to the playback command using the confirmation unit 140, and plays the NFT digital content corresponding to the playback command only if the owner matches the user. As described above, the confirmation unit 140 can confirm who the owner of the non-fungible token is for each NFT digital content, and can confirm whether the owner is the same person as the user who requested the playback of the NFT digital content.

[0043] The digital content playback unit 160 may include a playback module including a decoder capable of playing images, sound sources, videos, etc., for playing digital content, and thus may play various NFT digital contents. Here, the digital content playback unit 160 may apply various DRM technologies to prevent digital contents from being leaked to the outside, but the present invention is not limited by such DRM technologies. The more securely the digital content playback unit 160 manages the corresponding NFT digital contents so that users other than the owner cannot play them, the higher the value of the non-fungible token for the NFT digital contents may become.

[0044] The digital content playback unit 160 searches for and plays back the NFT digital content corresponding to the playback command in the digital content storage unit 150. As described above, the converted NFT digital content is stored in a playable form in the digital content storage unit 150, and by playing it in the digital content playback unit 160, it is possible to obtain an effect that the corresponding content can be used at any time through the digital content management system 101 of the present invention even if the user does not have the digital content in the form of a file or the like in the terminal.

[0045] The token trading unit 170 enables trading of non-fungible tokens generated for each NFT digital content, and includes the transaction history in the generated non-fungible token. The token trading unit 170 can provide a user UI in the form of an exchange so that the generated non-fungible tokens can be traded, and can convert owner information using blockchain technology when a transaction is concluded and a fee is paid. Due to the characteristics of blockchain technology, information on transaction history can be maintained, so that information on when and from whom the NFT digital content was transferred can be continuously managed, and therefore rights to each NFT digital content can be safely managed.

[0046] FIG. 2 is a diagram showing an example of converting digital content into NFT digital content of various qualities in a digital content management system according to one embodiment of the present invention.

[0047] In this example, the original digital content 201 is an audio source content, and a total of eight digital contents are generated by converting the digital content. As shown in the figure, eight converted NFT digital contents 210 to 280 can be generated. Here, as shown in the figure, the first NFT digital content 210 can be the same digital content as the original digital content, and the second to eighth NFT digital contents 220 to 280 can be digital contents in a form in which a part of the latter half of the original sound source has been removed.

[0048] Through this conversion, various NFT digital contents with different qualities can be generated, and non-fungible tokens can be generated for each NFT digital content, allowing owners to be managed, making it possible to trade various forms of content.

[0049] Although the figure shows an example of generating content of various qualities by adjusting the playable length of the sound source, various modifications are possible, such as converting the sound quality or evenly dividing the sound source to generate different content.

[0050] In addition to the digital content shown in the figure, a pre-listening sound source can be generated before the sound source, and this part can be played without securing separate ownership, making it useful for buying and selling.

[0051] FIG. 3 is a diagram showing an example of a case where a user who holds a non-fungible token for one of the NFT digital contents plays the corresponding content.

[0052] The example in the figure shows a case where a user owns a non-fungible token NFT3 corresponding to the third NFT digital content NFTDC3 and requests playback of the NFT digital content.

[0053] As shown by reference numeral 301, when a user requests the digital content playback unit 160 of the digital content management system 101 of the present invention to play back content, the digital content playback unit 160 checks the non-fungible token NFT3 to confirm the current owner of the token as shown by reference numeral 302. If the owner of the token is confirmed to be the same as the user who requested the playback, the digital content playback unit 160 reads the corresponding content NFTDC3 stored in the digital content storage unit 150 as shown by reference numeral 303, and plays it back to the user as shown by reference numeral 304.

[0054] A user who owns the NFT digital content converted through this process can play the digital content through the digital content management system 101 of the present invention without having to save the digital content on his / her own device, etc., and can block others from playing it.

[0055] FIG. 4 is a flowchart showing the flow of a digital content management method according to an embodiment of the present invention.

[0056] The digital content management method according to the present invention is a method for managing digital content in a digital content management system 101 having a central processing unit and a memory, and can be run on such a computer system.

[0057] Therefore, the digital content management method includes all the characteristic configurations described above for the digital content management system, and contents not described in the following description can also be implemented by referring to the description of the digital content management system described above.

[0058] In the digital content information receiving step (S401), digital content and the number of NFT contents to be generated based on the digital content are received. The present invention is characterized in that it converts digital content in a format into various versions and enables the owner to be identified for each version. The digital content may include sound sources, images, videos, etc., and in the case of sound sources, it may be in the form of a file in which sound sources are compressed and stored, such as MP3, in the case of images, it may be in the form of a file in which images are compressed and stored, such as JPEG, GIF, PNG, etc., and in the case of videos, it may be in the form of a file in which videos are compressed and stored, such as MP4, AVI, etc. In addition, all content that can be stored in a digital format, such as a text-type document file, may be subject to the present invention.

[0059] The number of NFT contents to be generated received in the digital content information receiving step (S401) indicates the type of version into which the received digital content is converted, as described above. For example, if the number of NFT contents to be generated is 10, a total of 10 types of converted digital content can be generated. One of these can be the original digital content received, the rest can be content into which the original content is converted, and in some cases, all can be content stored differently from the original.

[0060] In the digital content conversion step (S402), the digital content is converted to generate NFT digital content equal to the number of the received NFT contents. As described above, the digital content is converted based on the information on the number of NFT contents received in the digital content information receiving step (S401). Here, various conversion methods can be applied depending on the type of digital content.

[0061] Here, the digital content conversion step (S402) converts the digital content so that the generated NFT digital contents have different qualities. Non-Fungible Token (NFT) technology allows ownership information for one digital content to be managed safely and transparently using a blockchain, but when using this technology, only one owner is possible for one digital content, and the number of circulatable contents is limited, making it difficult to actively trade and generate profits from it.

[0062] Therefore, the digital content conversion step (S402) is characterized by converting one digital content into various versions so that each can be traded separately. In the case of multiple converted NFT digital contents, they are traded in the market at different prices by having slightly different qualities from the original. In this case, it is preferable that the conversion is performed so that at least a part of the original digital content can be used, even though there is a difference in quality.

[0063] For example, the digital content converted in the digital content conversion step (S402) may be a sound source content, and each of the generated NFT digital contents may be a content generated by shortening the playback time of the digital content. If an author wishes to manage the ownership of an unreleased sound source, if the original digital content has the entire playback time of the sound source, the first converted NFT digital content may be converted to a form in which the last 10 seconds are removed, and the second converted NFT digital content may be converted to a form in which the last 20 seconds are removed. In this way, by gradually adjusting the quality of the digital contents, it is possible to make them have relatively different values ​​and to have them trade at different prices in the market.

[0064] The non-fungible token generation step (S403) generates a non-fungible token for each of the generated NFT digital contents based on a blockchain. A non-fungible token (NFT) is a token that uses blockchain technology to generate a single token that can identify the owner of a piece of digital content, and stores information about the owner's change history in the token. The characteristics of decentralized blockchain technology make it possible to clearly identify the owner without centralized management.

[0065] In the non-fungible token generation step (S403), a token is generated for each converted NFT digital content, allowing the owner of each converted NFT digital content to be managed separately and traded separately. If 10 NFT digital contents are generated by conversion for one digital content, 10 non-fungible tokens (NFTs) are also generated.

[0066] In the non-fungible token generation step (S403), a token can be generated so that the owner of the original digital content can be registered as the owner of the entire converted NFT digital content. This allows the original owner, such as the author of the digital content, to convert their digital content into various versions, have ownership rights to each of them, and generate revenue by buying and selling some or all of them on the market.

[0067] In the confirmation step (S404), when the generated NFT digital content is played, the non-fungible token generated for the played NFT digital content is confirmed. Non-fungible token (NFT) technology is a technology that allows the owner of digital content to be confirmed, but does not manage the playback authority of the corresponding digital content. Therefore, the digital content management system of the present invention can control the confirmation of the owner of each content when playing digital content, and allow only the owner to play the digital content, or output the owner information of the digital content together when playing the digital content.

[0068] The confirmation step (S404) can confirm whether the final owner recorded in the token is the same as the user who requested the content to be played by checking the non-fungible token corresponding to the NFT digital content to be played. For this purpose, the confirmation step (S404) can request information such as a password that can confirm that the owner is the same as the owner recorded in the token from the user who requested the content to be played, and if the user is a subscriber to the content management system 101 of the present invention, information that can be confirmed by matching with the user of the token is stored as user information, so that the user can play the content without having to unnecessarily request confirmation information every time the user requests content to be played.

[0069] In the digital content storage step (S405), the NFT digital content generated through conversion in the digital content conversion step (S402) is stored in the digital content storage unit 150. As described above, digital content may include various types of content, but is ultimately stored in the form of a digital file. Thus, a digital file that stores information about the digital content is stored in a recording medium, and the converted NFT digital content can be played at the user's request. There are various methods for storing NFT digital content, but it is preferable to apply content security technology that can prevent leakage of content.

[0070] In the digital content playback step (S406), an NFT digital content playback command is received from a user, and the confirmation step (S404) confirms the owner information of the non-fungible token of the NFT digital content corresponding to the playback command, and only if the owner matches the user, the NFT digital content corresponding to the playback command is played. In addition, the confirmation step (S404) can confirm who the owner of the non-fungible token is for each NFT digital content, and can confirm whether this owner is the same person as the user who requested the playback of the NFT digital content.

[0071] The digital content playback step (S406) may include a playback module including a decoder capable of playing images, sound sources, videos, etc., for playing digital content, thereby playing various NFT digital content. Here, the digital content playback step (S406) may apply various DRM technologies to prevent the digital content from being leaked to the outside, but the present invention is not limited by such DRM technologies. The more securely the NFT digital content is managed in the digital content playback step (S406) so that users other than the owner cannot play it, the higher the value of the non-fungible token for the NFT digital content can be.

[0072] In the digital content playback step (S406), the NFT digital content corresponding to the playback command is searched for and played in the digital content storage unit 150. As described above, the converted NFT digital content is stored in a playable form in the digital content storage unit 150, and by playing it in the digital content playback step (S406), it is possible to obtain an effect that the digital content can be used at any time through the digital content management system 101 of the present invention even if the user does not have the digital content in the form of a file or the like in the terminal.

[0073] The token trading step (S407) allows non-fungible tokens generated for each NFT digital content to be traded, and includes the transaction history in the generated non-fungible token. The token trading step (S407) can provide a user UI in the form of an exchange so that the generated non-fungible tokens can be traded, and when a transaction is concluded and a fee is paid, owner information can be converted using blockchain technology. Due to the characteristics of blockchain technology, information on transaction history can be maintained, so that information on when and from whom the NFT digital content was transferred can be continuously managed, and therefore rights to each NFT digital content can be safely managed.

[0074] The digital content management method according to the present invention can be produced as a program for causing a computer to function and be recorded in a computer-readable recording medium.

[0075] Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks and magnetic tapes, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, etc.

[0076] Examples of program instructions include not only machine code, such as produced by a compiler, but also high-level language code executable by a computer using an interpreter, etc. The hardware devices may be configured to operate as one or more software modules to perform the processes according to the present invention, and vice versa.

[0077] Although the present invention has been described with reference to the preferred embodiments, those skilled in the art will recognize that various modifications and variations of the present invention may be made without departing from the spirit and scope of the present invention as defined by the following claims. and can be changed.
