Food Supply Chain Traceability using Block Chain

Abstract

In this paper, the main idea is to have a transparent food supply chain by the use of blockchain technology. The architecture uses an authentication protocol which is similar to the protocol involved in the crypto currency technology. For this feature to be available in all the products a radio frequency identification (RFID)-based sensor was used. The architecture is built by having the cyber layer having the Blockchain and RFID sensor in the physical layer. The main idea of RFID is to provide real time monitoring of data by the use of a unique identifier. For a food supply chain to be transparent, every product has to have a proper link to the concerned origin and the status of the products. In order to achieve this blockchain provides a highly secured digital database for each of the food products. In order to prevent cyber-attacks different security analysis was being conducted at different architectural stages.
