Embodiment 1

[0027] 1. The technical framework of the agricultural product traceability system is as follows: figure 1 , mainly divided into physical layer, communication layer, database layer and application layer. Among them, blockchain technology is applied to the database layer and communication layer.

[0028] 2. The physical layer mainly includes smart sensors and actuators, which are used for data collection and forwarding to the upper layer protocol, which is essentially similar to the physical layer in the Internet of Things structure. The password encryption technology and access control mechanism adopted by the equipment make it vulnerable to attack, and the supplier can strengthen its security from the aspects of routers and communication protocols.

[0029] 3. The communication layer mainly includes network structure and protocols. The communication layer of the traditional IoT architecture mainly uses communication mechanisms such as Bluetooth, Zigbee, wifi, Ethernet, and 3...

Abstract

The invention relates to a blockchain technology-base agricultural product traceability method. According to the method, a block chain technology is applied to the database layer and communication layer of a system; agricultural products are coded through a global unified identification system; a data entry process uses digital signatures and smart contracts, so that it can be ensured that data are not tampered; all the data are stored in a blockchain and can be accessed by authorized nodes; and the right of data access depends on the roles and functions of participants in a supply chain. Withthe method adopted, problems such as non-standard information collection, insecure data storage, the vulnerability of a central system to attacks and failure to ensuring privacies in the process of information exchange between enterprises of a traditional agricultural product traceability system can be solved.

Description

technical field [0001] The invention belongs to the fields of block chain technology and food safety, and in particular relates to a traceability method for agricultural products based on block chain technology. Background technique [0002] In recent years, food safety incidents have occurred frequently, and a series of quality and safety issues such as bird flu, clenbuterol, melamine, and rice cadmium exceeding the standard have triggered a crisis of consumer trust and are also a major challenge in the country's work in building and developing an honest society. The food traceability system can identify the source of food and provide detailed information on the whole process from production to table. Once a food safety accident occurs, the food traceability system can quickly and accurately locate the problem link, clarify the responsible party, recall the problem food in time, and curb the spread of the problem. This is one of the effective ways to solve the current food ...
