Intelligent UAV-based monitoring systems are becoming an essential apparatus for crowd monitoring as they have proven to be viable and cost-effective solutions. Applications of such systems may include detecting antisocial and abnormal behavior among a crowd to ensure public safety and security, especially during periods of pandemic or social unrest when technology is aimed at replacing the human factor to ensure scalability and reduce risk. On the other hand, the modern architectures of autonomous UAV-based systems requires processing the captured information at the edge and cloud facilities, which requires transmission and/or retransmission of the captured data. This vulnerability of data security during transmission may compromise the benefits of the technology. Therefore, there is need for an effective strategy to achieve a secure architecture that takes into consideration the limited computing capabilities onboard the UAV agents and the distributed nature of the system. Blockchain, as a distributed network technology, will provide a safe, transparent, and efficient network system for UAV systems. Therefore, this article proposes a drone-swarm-aided distributed monitoring system in a blockchain-powered network. In the proposed monitoring mechanism, the security protocol and encryption algorithm are applied to ensure the security of each stage of the system, so as to realize the cooperative drone swarm to reliably perform monitoring tasks. The blockchain technology is introduced to achieve tamper-proof monitoring log recording and support group decision making of monitoring transactions.

基于无人机群的基于区块链的安全人群监控系统

基于智能无人机的监控系统已被证明是可行且具有成本效益的解决方案,正成为人群监控的重要工具。这种系统的应用可能包括检测人群中的反社会行为和异常行为,以确保公共安全,特别是在大流行或社会动荡时期,当技术旨在替代人为因素以确保可扩展性并降低风险时。另一方面,基于自主UAV的系统的现代体系结构需要在边缘和云设施处处理捕获的信息,这需要传输和/或重新传输捕获的数据。传输过程中的数据安全漏洞可能会损害该技术的优势。所以,需要一种有效的策略来实现一种安全的体系结构,该体系结构要考虑到无人机代理上有限的计算能力以及系统的分布式性质。区块链作为一种分布式网络技术,将为无人机系统提供一个安全,透明,高效的网络系统。因此,本文提出了一种在基于区块链的网络中的无人机群辅助分布式监控系统。在提出的监控机制中,应用安全协议和加密算法来保证系统各个阶段的安全性,从而实现协同无人机群可靠地执行监控任务。引入了区块链技术以实现防篡改的监控日志记录并支持监控交易的组决策。
