Miniature (mini) drones are enjoying increasing attention. They have a broad market and applications. However, a powerful technology often has two ethical sides. Miniature drones can be abused, rendering security and privacy concerns. The contribution of this paper is two-fold. First, we will perform a survey of mini-drones on market and compare their specifications such as flight time, maximum payload weight, and price, and regulations and issues of operating mini-drones. Second, we propose novel aerial localization strategies and compare six different localization strategies for a thorough study of aerial localization by a single drone.
