A User Sensitive Privacy-preserving Location Sharing System in Mobile Social Networks

Abstract

Some types of social networking applications installed in the mobile devices require users to share own locations while using them. Adversaries glean users’ private information through shared locations via social networking application and public available geographic data. In this paper, we propose a user sensitive privacy-preserving location sharing system to avoid leaking. Users define sensitivity profiles to transform the public available geographic data into personal obfuscate region maps. Shared locations from obfuscate region maps provide close enough coordinates for application to use, but disconnected correlation between exact public available geographic data and user's actual location to prevent malicious tracking.
