ABSTRACT: A user’s trajectory can be
maliciously monitored by adversaries when they share the positions in
location-aware social networking applications which require users to update
their own locations continuously. An adversary infers user’s locations from the
trajectories, and gleans user’s private information through them via
location-aware social networking applications and public available geographic
data. In this paper, we propose a user proprietary obfuscate system to suit
situations for position sharing and location privacy preserving in
location-aware social network. Users transform the public available geographic
data into personal obfuscate region maps with pre-defined profile to prevent
the location leaking in stationary status. Our obfuscation with size restricted
regions method tunes user’s transformed locations fitting into natural movement
and prevents unreasonable snapshot locations been recorded in the trajectory.
