Agricultural product quality safety traceability method and system based on agricultural Internet of Things

Abstract

The invention relates to the technical field of agricultural product traceability, and discloses an agricultural Internet of Things agricultural product quality safety traceability method, which comprises the following steps: initializing a credible value of an agricultural product in an agricultural product production stage and a credible value of each traceability node in a traceability process; calculating to obtain a credible value in the agricultural product traceability process by using a credible value algorithm, and if a traceability node with a relatively low credible value exists in the agricultural product traceability process, considering that the agricultural product of the current traceability node has a quality safety problem; storing the data provided by each traceability node in the agricultural product traceability process and the credible value into a block chain node; and encrypting the blockchain node the stored data into a traceability two-dimensional code by using an encryption algorithm, so that a user can scan the traceability two-dimensional code to trace the agricultural product. The invention further provides an agricultural product quality safety traceability system based on the agricultural Internet of Things and achieves agricultural product traceability.

Description

technical field [0001] The invention relates to the technical field of traceability of agricultural products, in particular to a method and system for traceability of the quality and safety of agricultural products in the agricultural Internet of Things. Background technique [0002] In recent years, with the development of informatization in the agricultural industry chain and the improvement of people's living standards, people have paid more and more attention to the security and authenticity of information in the traceability system of agricultural products. [0003] Most of the traditional traceability systems of agricultural products use the central database to store information, and the information may be tampered with artificially, which makes consumers have great doubts about the authenticity of the traceability information. At the same time, users in different links participate in the traceability process as different traceability nodes. The lack of information fee...

[0003] Most of the traditional traceability systems of agricultural products use the central database to store information, and the information may be tampered with artificially, which makes consumers have great doubts about the authenticity of the traceability information. At the same time, users in different links participate in the traceability process as different traceability nodes. The lack of information feedback, the information is not open and transparent, resulting in the asymmetry of information held by each traceability node, the lack of trust between the two parties in the transaction, and a trust crisis is likely to occur
