Food sales tracing system

Abstract

The invention discloses a food sales tracing system, relates to the technical field of sales data traceability, and solves the technical problem of difficult traceability caused by sales data loss orunreality in a food sales process. According to the invention, the data acquisition module is arranged and is used for acquiring food information through communication connection with the Internet ofThings device, so that the data acquisition efficiency can be improved and the traceability accuracy of food sales can be ensured; according to the invention, the data display module is arranged to verify the identity information of the user before data display, so that the confidentiality of food sales data is ensured, and the traceability accuracy is further improved; the traceability is carriedout based on the blockchain technology, the blockchain adopts the P2P network technology, the asymmetric technology and the blockchain table mode to store the data, the characteristics of being tamper-proof and non-repudiation are achieved, and the primitiveness and credibility of the food sales data are guaranteed.

Description

technical field [0001] The invention belongs to the field of sales data traceability, relates to block chain technology, and in particular is a food sales traceability system. Background technique [0002] Food quality and safety traceability is an information management method that can connect production, inspection, supervision and consumption, so that consumers can understand the production and distribution process in line with hygiene and safety, and improve consumers' confidence; the blockchain adopts P2P network technology, non- Symmetrical technology, using the block chain table to store data, has the characteristics of non-tampering and non-repudiation. [0003] The invention patent with the publication number CN108389063A provides a product sales traceability system. A traceability identification code management module is set in the system, which assigns the promoter traceability identification code to the promoter, and the product buyer submits the traceability ide...
