| Research Abstract |
In this project, we proposed a novel privacy preservation framework that reduces the damage of privacy-invasion, caused if malicious services try to share our footsteps. We can set the degree based on our demand : the higher the degree, the harder services misuse our footsteps. Consequently, this framework enables us to utilize ubiquitous location-aware services even though these services might be unknown, untrustworthy, or malicious ones.
