DDRF: the Drone Data Regulatory Framework Based on Blockchain

Civilian UAVs have developed rapidly in recent years. However, due to the lack of supervision, cumbersome flight plan application process, and other problems, many people use drones at will, and many accidents occur as a result. We proposed a framework for using blockchain to regulate drone behavior and implemented a demo. With this framework, users don’t have to go through a complicated approval process to apply for a flight plan. Besides, because of the nature of blockchain, the system implemented based on our framework is transparent and decentralized, which meets the requirement of supervision. Information is authentic and all on-chain information is available for viewing. If there is a drone accident, the person responsible can also be identified based on immutable information records. Moreover, we also process the data to make the overhead of appending repeating data smaller and make automated data checks. The framework includes three modules, a data processing module, a data registration module, and a data audit module. Our demo implements these modules based on Hyperledger Fabric. We carry out experiments on the model, and the results showed our framework is efficient.
