Description

Special management forest product quality management system using block chain {QUALITY MANAGEMENT SYSTEM FOR SPECIAL FOREST PRODUCT USING BLOCKCHAIN}

The present invention relates to a specially managed forest product quality management system, and more particularly to a system that enables quality control of specially managed forest products using a block chain and smart contract.

Special management forest product is the legal name of wild ginseng, and wild ginseng is one of the classifications of ginseng, and its cultivation method is different from domestic ginseng, which we usually call ginseng. Wild ginseng refers to ginseng grown as closely as possible to wild ginseng and wild ginseng without using pesticides by sowing or transplanting in the production area. Since there is not much difference between wild ginseng and ginseng varieties, it is difficult for non-experts and ordinary consumers to distinguish between wild ginseng and ginseng. Therefore, the production process is managed by the 'Mountain Management Act' and the 'Act on the Promotion of Forestry and Mountain Villages', and quality is managed based on institutional trust by preparing a quality control process based on the law.

The quality control process manages the entire production process, from securing planting sites, seeds, and seedlings to distribution and sales. However, the entire process is managed through the 'Enforcement Rules of the Act on the Promotion of Forestry and Mountain Villages' and designated documents using its annexed forms, which puts the expression of the 4th industrial revolution era colorless. Even among the designated documents, the production process record book is manually prepared by a grower of specially managed forest products, and if it is submitted to a specialized institution every three years, on-site verification conducted together with submission of this document is all that is needed to verify the record.

Despite the fact that many documents are prepared and attached for the process, a lot of cost is consumed in administrative processing because it relies on a verification method based on institutional trust, not technical trust. In addition, among these verification methods, the institutionally prepared quality inspection pass certificate is the only way for consumers to check wild ginseng on sale. Since 90% of wild ginseng is sold directly to consumers, the case of ginseng that abused it to disguise itself as wild ginseng causes financial damage to consumers and lowers the reliability of all Sangyang ginseng farms. Therefore, it is necessary to establish a quality management system based on technological trust to solve the problem.

Currently, the system for quality control of specially managed forest products includes the Korea Forestry Promotion Agency's wild ginseng cultivation history inquiry and Hamyang wild ginseng production history system. In the case of wild ginseng cultivation history inquiry, authentic verification of the quality inspection pass certificate is performed, and since the history cannot be confirmed, the confirmation date for each process and the photo at harvest can be viewed. In the case of the Hamyang wild ginseng production history system, it is the first system in the country to record the production history of wild ginseng using a mobile phone. However, it is difficult to verify the record because it is possible to check the production photos and the date of photo registration, and it is impossible to check records for wild ginseng other than the local government.

In this regard, Korean Patent Registration No. 10-1871468 discloses a blockchain-based integrated agricultural and livestock product history management system. According to the prior literature, a system that increases reliability by storing integrated history information management of agricultural and livestock products on a blockchain and allows consumers to view integrated history information without restrictions is disclosed.

However, since prior literature still has problems with reliability because step-by-step verification is not performed, a quality control system capable of providing consumers with transparent information with high integrity and reliability by granting a final pass or failure through step-by-step verification is required. .

Through this, the specially managed forest product quality management system 10 allows stakeholders, consumers, producers, etc. to conveniently check whether wild ginseng is produced in a legal and appropriate production process.

The special management forest product quality control system 10 may record the quality inspection result requested by the specially managed forest product grower in the block chain through a smart contract. The special management forest product quality management system 10 may issue a pass certificate when a quality inspection application that satisfies the conditions set in the smart contract is entered.

The special management forest product quality management system 10 has the advantage of preventing illegal distribution by enabling to check the specially managed forest products that have not been certified in the distribution and sales process through the information recorded in the block chain.

Production suitability survey results, production process record results, and quality inspection results recorded by the specially managed forest product quality control system 10 were conducted by an existing specialized institution (Korea Forestry Promotion Agency) and stored as documents. The production report results recorded by the special management forest product quality control system 10 are those that have been carried out by existing local governments and stored as documents.

The first database 100 may store production documents of specialized institutions including production suitability investigation results, production process recording results, or quality inspection results. The first database 100 may convert and store data stored as offline documents in specialized institutions. The first database 100 may provide stored documents to the recording unit 300 to be recorded in the blockchain.

The second database 200 may store local government production documents including production report results. The second database 200 can convert and store data stored as offline documents in local governments. The second database 200 may provide stored documents to the recording unit 300 to be recorded in the blockchain.

The recording unit 300 uses a smart contract to record in the blockchain in the order of production suitability investigation results, production report confirmation results, production process confirmation results, and quality inspection results stored in the first database 100 or the second database 200. You can submit the calling transaction. The recording unit 300 may call a smart contract to record all information recorded in the first database 100 or the second database 200 in the block chain from the stage before production of wild ginseng to the stage of distribution and sales.

The recording unit 300 may generate an electronic document that satisfies a legal format using a smart contract. The recording unit 300 may submit a transaction to record the created electronic document in the blockchain. The electronic document information recorded in the blockchain by the recording unit 300 can be used as a means of verifying the referenced electronic document when referring to a document between interested parties.
