AMOEBA: Robust Location Privacy Scheme for VANET
Source: University of Washington
Communication messages in Vehicular Ad hoc Networks (VANET) can be used to locate and track vehicles. While tracking can be beneficial for vehicle navigation, it can also lead to threats on location privacy of vehicle user. In this paper, the authors address the problem of mitigating unauthorized tracking of vehicles based on the broadcast communications, to enhance the user location privacy in VANET. Compared to other mobile networks, VANET exhibits unique characteristics in terms of vehicular mobility constraints, application requirements such as a safety message broadcast period, and vehicular network connectivity. Based on the observed characteristics, they propose a scheme called AMOEBA that provides location privacy by utilizing the group navigation of vehicles.
