A privacy-preserving data collection scheme for smart agriculture based on edge blockchain

Abstract

Smart agriculture is a new agricultural production model integrating Internet, cloud computing and Internet of things, which provides precision planting and online services for agricultural production. The accuracy and reliability of agricultural data collection affect agricultural decision-making, so it is very necessary to protect agricultural privacy data. Existing solutions usually require the cooperation of trusted institutions, which is not practical. Blockchain adopts the PBFT consensus algorithm and does not require a trusted third party. Edge computing can greatly improve the efficiency of data aggregation and save data transmission time. Hence, this paper proposes a data collection scheme with a faulttolerant property based on blockchain and edge computing to protect sensitive information in smart agriculture. It is proved to be data security, privacy protection, and fault tolerance with the performance simulation and security analysis.
