Electronic product circulation traceability method and system

Abstract

The invention belongs to the technical field of circulation supervision of electronic products, and discloses an electronic product circulation traceability method and system. The method and system enable producers, middlemen and consumers to understand the whole process of circulation of electronic products, and solve the problem of difficult quality traceability. The method specifically comprises the steps that the information identifier of an electronic product is constructed according to the information of the electronic product; the information identifier and the factory record of the electronic product are encrypted, and the encrypted information identifier and factory record are stored in a blockchain; the intermediate transaction record of the electronic product from a factory to aconsumer is encrypted, and the encrypted intermediate transaction record is stored in the blockchain; and after the consumer purchases the electronic product, the factory record and the intermediatetransaction record of the electronic product are acquired from the blockchain through the information identifier, and the circulation process of the electronic product is acquired.

Description

technical field [0001] The invention relates to the technical field of circulation supervision of electronic products, in particular to a method and system for traceability of electronic product circulation. Background technique [0002] In the circulation process of electronic products, it is very necessary to trace them. People use this to understand the information of electronic products in each circulation link, so as to grasp the circulation status of products. [0003] In the existing technology, the usual product traceability method is as follows: before each product leaves the factory, a two-dimensional code is printed on its packaging. link, such as when entering the warehouse, the inspector scans the QR code on the product to obtain the relevant information when the product leaves the factory, and then enters the relevant information and the newly added inspection information into the database of the enterprise, such as when leaving the warehouse, By scanning the ...

AI Technical Summary

Problems solved by technology

[0004] However, there are still obvious defects in the existing technology. For example, in each circulation process of electronic products, the lower-level suppliers can only obtain the information of the upper-level suppliers of the products, but cannot understand the whole picture of the entire circulation process, especially for consumers. For example, it is even impossible to check the whole process of circulation, and can only query the factory information through the network, which cannot guarantee whether the information of electronic products has been tampered with in the middle circulation link. Therefore, in the existing technology, the traceability of electronic products is limited and cannot satisfy consumers Traceability requirements for electronic products
