LBSs take advan- tage of different positioning technologies and provide multiple applications. There are two kinds of positioning Application Programmer Interfaces (APIs) on Android plat- form devices: GPS provider and network provider. Network provider is implemented with network-based localization technology. This technology allows devices to deter- mine their locations and requesting LBSs in both outdoor and indoor environments. Nevertheless, network-based localization results contain extra information which re- veal privacy information to attackers. In this paper, we first point out these privacy threats. Some effects of network-based localization results are found and evaluated. Second, a specifically attacking strategy is proposed to re-identify LBS messages. The attacking results show that location privacy is a significant problems. Finally, a privacy protection scheme is developed to solve the privacy issue of network-based localization.
