Problems solved by technology

[0002] Product traceability has been proposed many years ago. With the continuous development of informatization and intelligence, the entire industry is also constantly exploring how to solve this problem. But so far, this problem has not been completely solved. The reason is that In addition to the fact that each link of the product has its own data and identification system, and it is difficult to connect the data of different links in series, what is more important is the problem of data tampering and data integrity.
[0003] When people go to the supermarket to buy things, they often see green, organic, anti-counterfeiting and other signs, but the credibility of the signs themselves is basically proved by the data provided by the company itself, but this does not guarantee the security and effectiveness of the provided data.

Embodiment 1

[0029] see figure 1 , figure 1 A schematic diagram of the steps of a product traceability method provided by the embodiment of the present invention is as follows:

[0030] Step S100, uploading the product data to each data node of the block chain library and obtaining the hash value;

[0031] In some embodiments, a blockchain node is a program running on a personal computer, virtual machine or server. Multiple blockchain nodes distributed on different computers or servers are connected to each other through the network to form a complete blockchain network. Blockchain nodes usually store blockchain data on personal computers, virtual machines or servers.

[0032] Blockchain nodes operate data through specific databases, such as stand-alone or distributed databases such as LevelDB, RocksDB, or MySQL. Compared with directly operating the disk, the database abstracts a specific data access model and is more friendly to blockchain nodes. Therefore, blockchain nodes save bloc...

Embodiment 2

[0045] see figure 2 , figure 2 A schematic diagram of the detailed steps of a product traceability method provided by the embodiment of the present invention is as follows:

[0046] In step S200, a blockchain library is established according to the characteristics of blockchain traceability, and the blockchain library is divided into a production database, an inspection database, a circulation database, and a transaction database.

[0047] Step S210, processing the data in the blockchain library according to the traceability information processing rule engine;

[0048] In step S220, the data processing objects include the data range, data type and data encryption method of the traceability information.

[0049] In some implementations, based on the characteristics of the traceability information, the on-chain standard of the traceability information is formulated. The on-chain standard includes the database and traceability information processing rules established accordi...

Embodiment 3

[0079] see image 3 , image 3 A schematic diagram of a product traceability system module provided by an embodiment of the present invention is as follows:

[0080] Upload module 10, for uploading product data to each data node of block chain storehouse and obtain hash value;

[0081] The integration module 20 is used to integrate the product data on each data node of the blockchain library to form a complete traceability chain;

[0082] Annotation module 30 is used to generate a product two-dimensional code according to the hash value of the product data and the traceability chain, and mark the generated product two-dimensional code on the corresponding production product;

[0083] The interaction module 40 is used to scan the two-dimensional code attached to the surface of the product and interact with the product data on the block chain;

[0084] The index module 50 is used to read the product data information of each node of the blockchain in the product two-dimensiona...

Abstract

The invention provides a product traceability method, and relates to the field of block chain traceability. The product tracing method comprises the steps of uploading product data to each data node of a block chain library and obtaining a hash value; integrating the product data on each data node of the block chain library to form a complete traceability chain; generating a product two-dimensional code according to the hash value of the product data and the traceability chain, and marking the generated product two-dimensional code on a corresponding produced product; scanning the two-dimensional code attached to the surface of the product to interact with the product data on the blockchain; reading product data information of each node of the block chain in the product two-dimensional code information, and sending an index instruction to carry out product traceability query. A real and credible product traceability chain is established by utilizing the characteristic that a blockchaincannot be tampered, and the authenticity problem of data is effectively solved, so a user feels that the data of each link is credible.

Description

technical field [0001] The present invention relates to the field of blockchain traceability, in particular to a method for product traceability. Background technique [0002] Product traceability has been proposed many years ago. With the continuous development of informatization and intelligence, the entire industry is constantly exploring how to solve this problem, but so far, this problem has not been completely solved. The reason is that In addition to the fact that each link of the product has its own data and identification system, and it is difficult to connect the data of different links, the more important issues are data tampering and data integrity issues. [0003] When people go to the supermarket to buy things, they often see green, organic, anti-counterfeiting and other signs, but the credibility of the signs themselves is basically proved by the data provided by the company itself, but this does not guarantee the security and effectiveness of the provided dat...
