Abstract: The ubiquity of smartphones and other location-aware hand-held devices has resulted in a dramatic increase in popularity of location-based services (LBS) tailored to users| locations. The comfort of LBS comes with a privacy cost. Various distressing privacy violations caused by sharing sensitive location information with potentially malicious services have highlighted the importance of location privacy research aiming to protect users| privacy while interacting with LBS. This paper presents a taxonomy of different approaches proposed to enable location privacy in LBS and elaborates on the strengths and weaknesses of each class of approaches.

Keywords: location privacy; location-based services; LBS; spatial databases; spatial query processing; taxonomy; privacy protection; information sharing; sensitive information; sensitive location information.
