Embodiment 1

[0024] (1) The blockchain-based food safety risk traceability analysis method and system architecture are as follows: figure 1 , It is mainly divided into database layer, communication layer and business layer. The database layer includes a blockchain structure and multiple database structures. The blockchain structure records the history of state changes. The State Database is a state database that records the latest status of transactions in the blockchain. The History Database is a historical database that stores Historical changes of status, Index Database is an index database, which stores index information. The nodes in the communication layer are assigned different roles, namely detection nodes (DTP) and supervision nodes (SVP), and different nodes can agree on transactions. The business layer operates on data through smart contracts. Among them, blockchain technology is applied to the database layer and communication layer of the system, and visualization technology ...

Abstract

The invention relates to a food safety risk traceability analysis method and a system based on a block chain. The block chain technology is applied to a database layer and a communication layer of thesystem, and the visualization technology is applied to a service layer of the system. Data upload requires the initiator's digital signature to ensure that the data is not tampered with and that thedata is stored in the block chain. Data access is controlled by permissions to access data in the chunk chain by executing smart contracts. Use Force-Directed Graph and flow maps show the food risk traceability process. When tracing the source of food safety risk, the user can trace the source of food safety risk through Force-Directed Graph Drills up to trace the source, then down to track the flow of food, Force-Directed Graph drill-through operations are shown in conjunction with a flow map in which arrows indicate the flow direction of risky foods, where different shades of color representdifferent degrees of risk flow. The invention not only solves the problems of unsafe storage of the traditional food traceability data and the vulnerability of the central database, but also providesa friendly visual interaction interface for users.

Description

technical field [0001] The invention relates to the fields of block chain technology, visualization technology, food safety, etc., and specifically relates to a block chain-based food safety risk traceability analysis system and method. Background technique [0002] Food safety is a systemic problem that involves a wide range of areas and is difficult to solve. In the traditional traceability, neither the encouragement of the state nor the efforts of enterprises can solve the biggest problem in the traceability and anti-counterfeiting of commodities - who will provide credible information. The traditional food safety management system is promoted by the government and covers the upstream and downstream of the entire food industry chain, including food production bases, food processing enterprises, and food terminal sales. Search online to find out all the circulation information of the food manufacturer, food origin, specific farmers, etc., and clarify the corresponding leg...
