Semantic and Sensitivity Aware Location Privacy Protection for the Internet of Things

Abstract. Everyday applications and ubiquitous devices contribute data to the Internet of Things, oftentimes including sensitive information of people. This opens new challenges for protecting users ’ data from ad-versaries, who can perform different types of attacks using combinations of private and publicly available information. In this paper, we discuss some of the main challenges, especially regarding location-privacy, and a general approach for adaptively protecting this type of data. This ap-proach considers the semantics of the user location, as well as the user’s sensitivity preferences, and also builds an adversary model for estimating privacy levels.
