Privacy Preserving Techniques and Deployment Types in Unmanned Aerial Systems

Unmanned Aerial Vehicles (UAVs) have garnered significant attention within the research community in recent years, with applications spanning from civilian to military use cases. The data generated by UAVs is susceptible and vulnerable to privacy breaches. Consequently, preserving privacy is crucial to safeguard this data against unauthorized access, and service providers must address this concern. This article establishes classification categories based on the required level of privacy preservation and provides an overview of the privacy-preserving techniques employed in Unmanned Aerial Systems (UAS). Additionally, the article offers insights into implementing privacy-preserving strategies across different levels, namely Type1, Type2, and Type3 in UAS. These deployment types can be combined to achieve a heightened level of privacy per the specific requirements. Lastly, the article compiles a table listing the attacks that privacy-preserving techniques can address and highlights the future challenges in this field.
