Abstract
This article analyzes and summarizes the current 5W1H problems faced by the Agricultural Product Traceability System. In order to solve these problems, based on the Permissioned BlockChain technology and Cryptographic technology, a logical framework for the safety and reliable Agricultural Product Traceability System is designed. The framework uses data encryption and flexible access control to protect data privacy and security of participants in the traceability system. A safe and reliable three-dimensional agricultural product traceability mechanism of “Combination of Peacetime and Wartime” + “Criss-Cross” is proposed. With the help of Smart Contracts, the agricultural products traceability data can be shared safely in time and matter. Effectively solve the problem of not being able to obtain real traceability data. It can not only trace the responsible party, but also ascertain the truth of the security incident. The research results of this paper provide theoretical support for the research of Agricultural Product Traceability System.
