Abstract: In recent years, multi-rotor unmanned aerial vehicle have developed quickly and have been widely used in fields and industries all over the world. However, due to the lack of effective safety strategies and the incomprehension of related flight regulations and the deliberate sabotage of laws and regulations of some users, incidents of illegal and random flights, illegal usage and hostile attacks increase day by day. This presents a significant challenge to the healthy development of the unmanned aerial vehicle industry and the safety and stability of the society. Therefore, taking measures such as the identity authentication and information forensics of unmanned aerial vehicle and their users can be beneficial to solve the above prominent problems. The forensics system of unmanned aerial vehicle is put forward for the first time in this paper. The system can acquire in advance and store the images, videos and other digital information on the illegal actions of users, so it can better solve the above problems. Meanwhile, this paper puts forward the authentication mechanism to confirm the three identities of users. Based on users’ actions, this paper develops an analysis model of users’ threat level and evaluates the model. The result shows that the model can accurately distinguish threats from users and provides accurate forensics standards for the forensics system of unmanned aerial vehicle.

Key words: unmanned aerial vehicle, forensics system, triple authentication
