A Free Terrain Model for Trajectory K–Anonymity (original) (raw)

Lecture Notes in Computer Science, 2008

Abstract

This paper introduces a privacy model for location based services that utilizes collected movement data to identify parts of the user trajectories, where user privacy is at an elevated risk. To protect the privacy of the user, the proposed methodology transforms the original requests into anonymous counterparts by offering trajectory K–anonymity. As a proof of concept, we build a working
