背景技术Background technique
产品质量追溯当发生产品发生质量事故时，能够提出恰当的应对措施，降低消费者的损失，使得消费者的利益能够得到保障。例如汽车行业的召回制度就是以产品追溯体系为基础。产品质量追溯帮助企业建立品牌形象，提升社会效应和经济效益。全程化的追踪管理，既加强了企业质量管理，减少了纠错成本，并且方便企业收集商品情报了解消费趋势，提高快速响应能力。而高效率的质量追溯方法可以提升国家产品整体质量水平，最大限度减少产品伪造假冒风险，提高产品满意度。但产品生产、流通和交易环节众多，交易数据量巨大，每个环节都可能出现产品质量问题，本发明提供一种利用区块链实现产品质量追溯的方法，获得每个环节的真实交易数据，并利用区块链技术记录信息，保证产品信息的可追溯。Product quality traceability When a product quality accident occurs, appropriate countermeasures can be proposed to reduce the loss of consumers and ensure the interests of consumers. For example, the recall system of the automobile industry is based on the product traceability system. Product quality traceability helps enterprises establish brand image and enhance social and economic benefits. The whole-process tracking management not only strengthens the quality management of the enterprise, reduces the cost of error correction, but also facilitates the enterprise to collect product information to understand consumption trends and improve the ability of rapid response. The high-efficiency quality traceability method can improve the overall quality level of national products, minimize the risk of product counterfeiting and improve product satisfaction. However, there are many links in product production, circulation and trading, and the amount of transaction data is huge, and product quality problems may occur in each link. The present invention provides a method of using blockchain to trace product quality to obtain real transaction data in each link. And use blockchain technology to record information to ensure the traceability of product information.
区块链技术是一种多技术的组合，它首先在比特币中应用，挖矿挖出的比特币和比特币交易依靠区块链认证和记录，在比特币的每个区块链中记录着完整的交易信息，每个区块链节点都可参与交易认证。Blockchain technology is a combination of multiple technologies. It was first applied in Bitcoin. Bitcoin and Bitcoin transactions mined by mining rely on blockchain certification and records, which are recorded in each blockchain of Bitcoin. With complete transaction information, each blockchain node can participate in transaction authentication.

结合附图，对本发明做进一步的阐述。In conjunction with the accompanying drawings, the present invention is further described.
利用本发明方法及系统，分配给产品交易环节的主体唯一交易主体ID和唯一交易主体令牌ID，并对每次交易环节分配唯一ID，其中交易主体ID和交易主体令牌ID可以是国家主管部门分配，类似工商部门为企业发放的证照号，只是交易主体ID可公开，而交易主体令牌ID是不公开的；而产品交易环节包括生产、运输、仓储、交易等环节，交易主体ID、交易主体令牌ID、每次交易环节ID，在本实施例中采用UUID识别码，Using the method and system of the present invention, the unique transaction subject ID and the unique transaction subject token ID are assigned to the subject of the product transaction link, and a unique ID is assigned to each transaction link, wherein the transaction subject ID and the transaction subject token ID can be national supervisors Departmental allocation is similar to the license number issued by the industrial and commercial department for enterprises, except that the ID of the transaction subject can be disclosed, while the token ID of the transaction subject is not; while the product transaction link includes production, transportation, warehousing, trading and other links, the transaction subject ID, The token ID of the transaction subject and the ID of each transaction link, in this embodiment, the UUID identification code is used,
针对每次交易，交易信息可以包括交易主体ID，标注为UUID01，交易主体令牌ID，标注为UUID02、本次交易环节ID，标注为UUID1，下一次交易环节ID，标注为UUID2、上一次交易环节ID，标注为UUID31，……直至第一次交易环节ID，标注为UUID3N，交易信息还包括时间戳和交易详情，如果没有上一次交易环节ID或下一次交易环节ID，则没有的上一次交易环节ID或没有的下一次交易环节ID项填空；交易主体上报每次交易信息，并将交易信息利用私钥加密，可防止信息泄露、信息造假和抵赖；For each transaction, the transaction information can include the transaction subject ID, which is marked as UUID01, the transaction subject token ID, which is marked as UUID02, the current transaction link ID, which is marked as UUID1, the next transaction link ID, which is marked as UUID2, the last transaction Link ID, marked as UUID31, ...until the first transaction link ID, marked as UUID3N, transaction information also includes time stamp and transaction details, if there is no last transaction link ID or next transaction link ID, then there is no previous transaction Fill in the blanks for the transaction link ID or the next transaction link ID if there is no one; the transaction subject reports each transaction information and encrypts the transaction information with a private key to prevent information leakage, information falsification and denial;
区块链接收交易主体每次上报的交易信息，对交易信息以交易主体的公钥解密，比对解密后交易信息中的交易主体令牌ID与区块链保存的交易主体令牌ID是否一致，一致则接受当次上报的交易信息，否则拒绝，进一步防止信息造假和抵赖；The blockchain receives the transaction information reported by the transaction subject each time, decrypts the transaction information with the public key of the transaction subject, and compares whether the transaction subject token ID in the decrypted transaction information is consistent with the transaction subject token ID stored in the blockchain , if consistent, accept the transaction information reported that time, otherwise reject it, further preventing information falsification and denial;
区块链以Key/Value形式存储交易信息，其中交易环节ID为key,其他交易信息为Value，并且区块链的每个区块中记录着交易主体ID（UUID01）、交易主体令牌ID（UUID02）、本次交易环节ID（UUID1）、下一次交易环节ID（UUID2）、上一次交易环节ID（UUID31）、……直至第一次交易ID（UUID3N）、时间戳和交易详情，每次交易信息在系统中不可更改；The blockchain stores transaction information in the form of Key/Value, where the transaction link ID is the key, and other transaction information is the Value, and each block of the blockchain records the transaction subject ID (UUID01), transaction subject token ID ( UUID02), this transaction ID (UUID1), the next transaction ID (UUID2), the last transaction ID (UUID31), ... until the first transaction ID (UUID3N), timestamp and transaction details, each time Transaction information cannot be changed in the system;
当进行质量追溯时，只需要以交易环节ID进行查询，就可追溯到上一次交易环节ID和查询到下一次交易环节ID，然后根据查询到的上一次交易环节ID或下一次交易环节ID再进行查询，可查询到更上一次交易环节或更下一次交易环节的详情，利用递归方式进一步追溯，直到没有上一次交易环节或下一次交易环节为止。其中，上述过程还可以将交易环节ID以二维码方式展现，用户扫描二维码就可方便地进行追溯，查询某个产品的产地、生产、运输过程等。When performing quality traceability, you only need to query the ID of the transaction link to trace back to the ID of the previous transaction link and query the ID of the next transaction link. By querying, you can query the details of the last transaction link or the next transaction link, and use the recursive method to further trace until there is no previous transaction link or next transaction link. Among them, the above process can also display the ID of the transaction link in the form of a QR code, and the user can easily trace it by scanning the QR code, and inquire about the origin, production, and transportation process of a certain product.
