| Abstract | In this paper we present an approach to support privacy in people-centric sensing. In particular, we propose a technique that allows a central authority to select a subset of users whose past positions provide a good coverage of a given area of interest, without explicitly georeferencing them. To achievethis goal, we propose an efficient algorithm to solve the wellknown, N P -complete Set Cover problem that does not requireexplicit knowledge of the sets, but only uses their compact,privacy preserving representations or sketches. We perform athorough experimental analysis to evaluate the performance ofthe proposed technique and its sensitivity to a few key parameters using public data from real applications. Experimental results support the effectiveness of the proposed approach to efficiently produce accurate environmental or social maps, at the same time preserving users’ privacy. |
