Mobile online social networks (mOSNs) become more and more popular, and compared with traditional OSNs, mOSNs take a step further in that they provide the location-based services, which also raise significant privacy concerns. Location sharing is a fundamental component of mOSN, however, users may be hesitant to share locations if privacy is not guaranteed. In this paper, we present a new privacy-preserving location sharing system for mOSN, which is flexible to support a variety of location-based applications, in that it enables location sharing between both trusted social relations and untrusted strangers. In this system, threat models are further analyzed and users' location privacy is proved to be preserved.
