主 题：location privacy location-based service internet of vehicles vehicular networks
摘 要：Ubiquitous information exchange is achieved among connected vehicles through the increasingly smart *** concept of conventional vehicular ad hoc network is gradually transformed into the Internet of vehicles(IoV).Meanwhile,more and more locationbased services(LBSs)are created to provide convenience for ***,the frequently updated location information sent to the LBS server also puts user location privacy at ***,preserve user location privacy while allowing vehicles to have high-quality LBSs is a critical *** solutions have been proposed in the literature to preserve location ***,most of them cannot provide real-time LBS with accurate location *** this paper,we propose a novel location privacy-preserving scheme,which allows vehicles to send accurate real-time location information to the LBS server while preventing being tracked by *** the proposed scheme,a vehicle utilizes the location information of selected shadow vehicles,whose route diverge from the requester,to generate multiple virtual trajectories to the LBS server so as to mislead *** results show that our proposed scheme achieves a high privacy-preserving level and outperforms other state-of-the-art schemes in terms of location entropy and tracking success ratio.
