Title
Protecting location privacy in opportunistic mobile social networks.
Abstract
Users face location- privacy risks when accessing Location-Based Services (LBSs) in an Opportunistic Mobile Social Networks (OMSNs). In order to protect the original requester's identity and location, we propose a location-privacy obfuscation protocol Multi-Hop Location-Privacy Protection (MHLPP) protocol that utilizes social ties between users. To increase chances of completing obfuscation operations, users detect and make contacts with one-hop or multi-hop neighbor friends in social networks. Encrypted obfuscation queries avoid users learning important information except for the original requester who generates queries and trusted users, especially the original requester's identity and location. Simulation results show that our protocol can give a higher query success ratio compared to its existing counterpart.
