A blockchain-based smart agriculture privacy protection data aggregation scheme

Smart agriculture is a new agricultural production mode. The Internet of things has been widely used in smart agriculture. The goal is to monitor, collect and effectively employ the relevant data of agricultural process, so as to realize the sustainable development of modern agriculture. The accuracy and reliability of the collected data affect the intelligent decision, so the security and privacy protection of the data are very necessary. Data aggregation solution is one of the most commonly used methods to solve the privacy protection and security problems of data collection. Existing solutions generally require the collaboration of a trusted authority, which may not be practical. Blockchain is a new distributed protocol that can be decentralized. Hence, this paper proposes a privacy protection data aggregation solution with a fault-tolerant property based on blockchain in smart agriculture. It is proved to be data security, privacy protection.
