Abstract

The present application relates to a method for providing product traceability, the method comprising: determining the origin information of each product batch in a plurality of product batches; combining the origin information of each product batch with satellite positioning data and standard time The data is fused and the first hash value is calculated, and the blockchain batch code is generated based on the first hash value; the product information of each single product of the smallest packaging unit in the current batch of products is determined and the second hash is generated value, generate a blockchain product code based on the second hash value; form a predetermined number of single products into a product logistics unit and equip the product logistics unit with a satellite positioning chip, obtain location information and combine the location information with the predetermined number of single products Each individual product in the overall product is associated and stored in the block chain; hash calculation is performed on the combination of the first and second hash values ​​to generate a third hash value, which is generated based on the third hash value The private key of the current batch of products.

Description

technical field

[0001] The present application relates to the field of network information processing, and more specifically relates to a method, system and server for providing product traceability. Background technique

[0002] The traceability system is used to realize the two-way traceability function of all batches of products from raw materials to finished products, and from finished products to raw materials. The main functions of the traceability system include data security, and each input link can be backed up in real time by software. After the traceability system is established, once a product-related accident occurs, supervisors can use the traceability system to judge whether the company has negligent behavior. In addition, the enterprise can also use the traceability system to find out the links, steps and responsible persons of problems. The traceability system avoids the difficulties in handling accidents due to incomplete information and unclear responsib...
