Technical Field
The invention relates to the technical field of e-commerce product quality tracing, in particular to a rural e-commerce product quality tracing system based on double chains.
Background
With the rapid development of rural electric commerce, some safety problems related to agricultural product supply chains are gradually exposed, for example: the vegetables are left with excessive pesticide, stored and stored for a long time are aged and grain, products lack standards and quality certification, and the vegetables are three products (no production date, no quality qualification certificate and no manufacturer), and the like, wherein many products threaten the health and life safety of people, but the general public is difficult to identify, and once food safety problems occur, consumers cannot find responsible persons even.
The existing rural E-commerce product quality tracing technology comprises the following steps: one is to trace back the relevant information after harvesting the agricultural products or the information in the circulation process after processing into finished products, such as quality tracing in a box and horse supplier system. The method is to record all-chain information in the processes from collection to circulation, but mainly adopts a manual data input mode, the data are often filled before selling, what needs to be displayed is filled, and the authenticity of the quality data cannot be guaranteed. In addition, the traceability information of all links is stored in a core unit of a certain link in a centralized way, and the participation units of the whole chain are low in enthusiasm for sharing data due to worry about the safety and privacy of the data; since the data is stored in a single unit, there is a possibility that the data is tampered with, and the public confidence is insufficient.
At present, with the increasing importance of consumers on rural e-commerce products, some manufacturers of large supermarkets and rural e-commerce products have started to push out related traceability systems.
