Description

Blockchain technology-based content transaction system and its control method The present invention relates to a content trading system and a method for controlling the same, and more specifically, to a system in which an electronic contract is executed between a seller and a buyer on a blockchain system and the content is disclosed sequentially according to the contract stage, and a method for controlling the same. NFTs utilize cryptographic technology to assign separate, unique identification information to digital content such as paintings, videos, and music. Unlike fungible tokens, the information contained within the blocks includes unique identifiers and data regarding the underlying asset, so each token possesses unique characteristics. NFT technology can prove the originality, authenticity, and uniqueness of digital content, as well as verify ownership and purchase history. As digital tokens that guarantee ownership by inputting unique recognition values, such as buyer information, into computer files using blockchain technology, NFTs can serve as digital original certificates or ownership certificates that allow for the recording and trading of digital representations or works of art. Technology transactions are primarily conducted offline. As for online systems to support technology transactions, only systems that allow viewing the content of the technology on web pages are provided and operated. For technologies that are already publicly disclosed and protected by intellectual property rights, it is possible to fully disclose the technical details through a webpage and conduct transactions through the transfer of registered intellectual property rights based on the disclosed technical details. However, in the case of know-how (trade secrets) or recipes that are not registered as intellectual property rights, there are no effective trading methods because it is impossible to fully disclose the relevant details. FIG. 1 is a conceptual diagram of a content trading system according to one embodiment of the present invention. FIG. 2 is a flowchart of a DID issuance procedure on a content trading system according to one embodiment of the present invention. FIG. 3 is a diagram illustrating a flowchart for registering information about content step by step according to an embodiment of the present invention. FIG. 4 is a diagram illustrating a flowchart of management regarding viewing based on DID according to an embodiment of the present invention. Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted. Additionally, while embodiments of the present invention will be described below, the technical concept of the present invention is not limited or restricted thereto and can be modified and implemented in various ways by those skilled in the art. Furthermore, the terms used herein are for the purpose of describing embodiments and are not intended to limit or/or restrict the disclosed invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising,” “having,” or “having” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and do not preclude the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Additionally, throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected" but also cases where they are "indirectly connected" with other elements in between. Terms including ordinal numbers, such as "first," "second," etc., used in this specification may be used to describe various components, but the components are not limited by these terms. Below, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the invention. Additionally, parts of the drawings that are irrelevant to the description are omitted to clearly explain the invention. FIG. 1 is a diagram illustrating a conceptual diagram of a content trading system (100) according to one embodiment of the present invention.
