Query-Aware Location Privacy model based on p-sensitive & k-anonymity for Road Networks
Recently, location leaks of an un-rrusted locationbased server chased plenty of work in location protection. However, previous techniques that protected user location privacy for location-based services in the Euclidean space would lead to privacy leakage and inefficient query processing while directly applied to the road network environment. In this paper, we propose a query-aware location privacy model based on p-sensitive & k-anonymity for road network environment. By cloaking a users location into p connected road segments which include at least k users, our model is able to meet better privacy requirements, and to minimize the query processing cost. Finally, we formally analyze the cost of our model under feasible assumption by using mathematic calculating.
