Modeling Tobacco Traceability System Based on Blockchain and RFID Technologies

Abstract

The existing tobacco traceability systems ignore the environmental factors that affect the quality of tobacco in the whole supply chain, and the authenticity of the information is difficult to guarantee. Therefore, it is necessary to establish a trusted traceability system for tobacco to ensure the product quality and improve consumer satisfaction. Based on blockchain and radio frequency identification (RFID) technology, this paper models a tobacco traceability system, focusing on the traceability of environmental data in the entire tobacco supply chain. Using the RFID and blockchain technology, we build the traceable coding architecture and traceability mechanism for the tobacco supply chain, and upload trusted data to the blockchain, thus ensuring the authenticity and accuracy of data in the entire supply chain process.
