Abstract
The rapid development of the Unmanned Aerial Vehicle(UAV) brings much convenience to our life. However, security and privacy problems caused by UAVs are gradually exposed. This paper analyzes UAV safety from three aspects, including sensors, communications and multi-UAVs. A UAV relies on different sensors to locate and calculate its flight attitude, which means spoof and attacks on sensors are fatal. On the one hand, wrong information from sensors will lead UAVs to make wrong judgments. On the other hand, damage to sensors can cause UAVs to fail to obtain information and severely cause UAVs to crash. Information exchange between UAV and Ground Control Station(GCS) relies on communication links and an unsafe link is susceptible to attacks. Multi-UAVs applications rely on stable network among UAVs. Ad-hoc network the mainstream of current networking method but it still exists many potential dangers. Besides, another possibility of privacy disclosure caused by aerial photos is also mentioned. These photos often contain private information such as location and shooting time which is likely to be leaked when the photographer shares photos on social applications. Finally, we summarize the paper and discuss the future research direction.
