Thousands of projects are challenging to make various platforms into DApps using blockchain as they go through the 1st generation Bitcoin, 2nd generation Ethereum, and 3rd generation EOS. Most of the DApps that have been carried out so far have been developed and released using the Ethereum blockchain, but a burdensome fee (gas fee), transaction processing speed problem, anonymous account problem, and blockchain account creation under the name of a corporation or institution It has not been able to overcome the barrier of commercialization due to problems that cannot be done. Furthermore, in non-financial fields other than the financial field, it is difficult to find an active DApp using the net function of the block chain. Although blockchain can be used in various fields, the field that can achieve the most effective convergence using the net function of blockchain is the industrial design field.

At this time, a platform for managing content copyright based on block chain was researched and developed.

The present invention will be described in the above four broad frameworks. Hereinafter, while describing with reference to FIG. 2 , when a concept or program necessary to explain FIG. 2 exists, it will be described with reference to FIGS. 3 to 4 . The storage unit 310 may receive and store drawing data in at least one format from the creative terminal 100 . In this case, the drawing data in at least one format may be 2-dimentional (2D), 3-dimentional (3D), virtual reality (VR), augmented reality (AR), and 3D printing data.

Referring to FIG. 3E , in order to activate the platform (maker's market) according to an embodiment of the present invention, the present applicant has secured about 370,000 drawing data. In other words, after signing a technology transfer contract with Sungchang Machinery, we secured 370,000 drawing data. Sungchang Machinery Co., Ltd. is a traditional engineering company that has manufactured key manufacturing facilities and equipment for 46 years. holds data. At this time, the present applicant has secured data in various fields such as industrial machinery, parts, mechanical equipment, and construction through a technology transfer contract with Sungchang Machinery Co., Ltd. In addition, various partnerships and MOUs have been signed to provide data and expand services on the platform according to an embodiment of the present invention.

Referring to Figure 3e, the platform according to an embodiment of the present invention has completed the development of the Ethereum-based Makers Market and started commercial testing, but the Ethereum-based Makers Market has solved problems such as low transaction processing speed and high fees. Because we had it, we decided to use EOS-based blockchain technology because of the need to use advanced smart contracts (smart contracts). In addition, smart contracts for industrial design creators and copyright protection can be implemented. Referring to FIG. 3f , the data consumer is a drawing data consumer such as an individual or an institution participating in the maker's market platform according to an embodiment of the present invention, and the data consumer requests industrial design drawing data or copyrights they need, and tokens You can pay to receive the information. In addition, data consumers can use the community to judge the reliability of data, and design to receive rewards according to their contribution.

Referring to FIG. 3G , an embodiment of the present invention provides a smart contract, and the smart contract can be executed for each transaction of a drawing and a copyright. Drawing data providers such as creators are rewarded with tokens whenever a transaction occurs, and each transaction record can be permanently recorded on the blockchain of the Makers Market platform. The biggest advantage of smart contracts is that it automatically handles transaction records, copyright records, and transfer of usage rights, distributed contracts cannot be modified, and it is not easy to change data without meeting unspecified contract criteria. Drawing data can be trusted.

Referring to FIG. 3h , it is a diagram for explaining a block-chain-IPFS interworking design for storage and management of large-capacity industrial design drawing data. At this time, IPFS (Inter Planetary File System, Distributed Storage System) was created for the purpose of connecting file standards and systems of computers around the world as a distributed file system. It is a P2P distributed file system that can make the web faster, safer and more open. It is a form of dividing large files into several pieces through P2P communication of nodes without a centralized server. However, the amount of data that can be stored in the block chain is very limited. Because only text can be recorded, it can be designed in conjunction with the block chain and IPFS so that large data such as photos and drawings can be shared through the Makers Market platform. In the block chain, hash values, which are IPFS data location information, can be stored, and data encrypted with a symmetric key can be stored inside IPFS. First, ① Encrypt the original industrial design drawing data with a symmetric key and upload it to IPFS, ② After encrypting the symmetric key with the seller’s public key, store the IPFS file link and the encrypted symmetric key in the block chain, ③ When selling, After decrypting the symmetric key with the seller's private key, encrypt it again with the buyer's public key and store it in the blockchain. ④ Decrypt the symmetric key with the downloader's private key. ⑤ When downloading, you can proceed in the order of securing the original drawing data with the symmetric key from step ④.

Referring to FIG. 3i, the blockchain-based industrial design drawing data transaction service can be activated, creating a new market called industrial design drawing data transaction service, and prototyping, BM, and 3D printing of the maker’s market platform through technology verification (PoC). It is possible to create a new market for 2D/3D drawings, AR/VR drawings, costume design drawings, and 3D printing drawings through drawing interlocking support and blockchain technology verification. In addition, 3D printing can be popularized through verification of 3D printing drawings linked with educational institutions. Currently, live-action printing using 3D printers such as Seoul National University Idea Factory, Sungkyunkwan University Learning Factory, Konkuk University Seongsu Maker Space, and Hongik University GLUCK is possible. There is a 'maker space'. There are various 3D printers in the makerspace, but due to the problem of compatibility between drawing S/W, 3D printing drawings that can be printed in real life are limited. Therefore, it is possible to provide drawings that can be printed on various 3D printers to educational institutions including makerspaces through 3D drawing interworking support according to an embodiment of the present invention. In the future, an embodiment of the present invention may establish an offline infrastructure that can help the commercialization of individuals and students who do not have a 3D printer for the popularization of 3D printing.

The upload unit 330 may generate and upload a transaction ID to identify the transaction. Referring to Figure 3j, it is basic to be able to record transactions based on blockchain, and the first commercialization of blockchain technology applied to the transaction area of industrial design drawings for the first time in Korea through functional and design verification of the blockchain-based maker's market platform prototype You can verify the prototype by launching the service. In addition, it is possible to verify the BM of illegal theft and distribution/sale of industrial design drawings through smart contract-based creator and copyright protection and compensation system model verification. And, it is possible to verify that the drawing data generated through the 3D printing drawing SW (Tadacraft) is linked with educational institutions to activate and popularize the 3D printing industry. In addition, KYC-based real-name authentication, personal and institutional block chain account creation, and blockchain test bed environment capable of high-performance transaction processing speed are promoted to verify technology, thereby promoting safe protection of creators and copyrights and commercialization of a trust-based drawing transaction platform. By doing so, it is possible to verify the blockchain technology.

Referring to Figure 3k, it shows the blockchain-IPFS linkage technology, and Figure 3l shows the KYC-based real-name authentication account creation and personal and institutional blockchain account creation technology. The platform according to an embodiment of the present invention supports the creation of a KYC-based real-name blockchain account, enabling copyright protection and a reasonable compensation system for creators and creations of industrial design drawings, and blocks for corporations and institutions as well as individual accounts. It is possible to create a chain account, so not only individual transactions within the platform, but also corporations and institutions can participate in drawing transactions.

The compensation unit 340 may pay compensation to the creative terminal 100 through a smart contract. The creative terminal 100 may receive compensation through a blockchain-based smart contract when the purchase and payment of drawing data occurs. At this time, referring to FIG. 3M, the smart contract is designed in such a way that the reward is returned to the creator by executing the smart contract whenever an industrial design drawing transaction occurs to compensate the creator, so that the transaction record, the record of the copyright holder, and the transfer of the right to use can be handled. have. Referring to FIG. 3N , as a review reward, only the trader can write a review at the time of completion of the transaction, and at the time of writing, at least one purchased industrial design drawing-related photo and an evaluation and total rating for the creator must be presented. If you write a review that satisfies all of the above conditions, 1% of the transaction price can be compensated.

Grade compensation is processed using a smart contract as a differential compensation payment according to the creator grade, as shown in Figure 3o and Table 2 below.

rank Condition Benefits Basic Default automatic conversion when applying for creator no benefit Star 1. More than 2 recent (6 months) transactions

Figure 3p shows a prototype of the platform of the present invention. The drawing transaction service may proceed to search for a transaction ID as shown in FIG. 3T after proceeding with drawing payment as shown in FIG. 3S. When the consumer selects a drawing to purchase and proceeds with payment, payment can be made easily and conveniently with the QR code linked to the blockchain-based wallet, and by pressing the transaction ID of the purchased drawing, the transaction details on the block chain can be checked as shown in Figure 3u. . 3v is a creator reward, and FIG. 3w is a review reward. In the platform according to an embodiment of the present invention, a reward is paid to the creator through a smart contract whenever a drawing transaction occurs, and the buyer (consumer) is compensated for writing a review It is processed through a smart contract. The program for this is as shown in FIG. 3x. The interworking unit 350 may control the demand terminal 400 to perform integrity check and block conversion with a pre-stored 3D modeling program using the drawing data, and then output to a 3D printer. have. Referring to Figure 3y, 3D modeling data (FBX, STL, etc.) obtained from various 3D authoring tools such as CAD, 3DSMax, and Asset Store is converted into a block shape so that it can be used in the 3D modeling program 'Tadacraft', and this data is converted You can even edit it in 'Tadacraft' by importing it to be usable.
