Location Privacy Protection Approaches in Mobile Networks

PhD Qualifying Examination


Title: "Location Privacy Protection Approaches in Mobile Networks"

by

Mr. Junliang Liu


Abstract:

Providing valuable information according to user locations,
Location-based Service (LBS) has become increasingly important for
wireless and mobile networks. In current LBS schemes, Service
Providers (SPs) require users to report their accurate, continuous,
and real-time locations, which may be illegally used by malicious
adversaries to infer sensitive information of users. Privacy
disclosure raises the concerns of LBS users and limits the application
of LBS. This survey will discuss the problems concerning location
privacy. We begin by examining potential threats against location
privacy. Then we introduce the major existing location privacy
protection strategies, which can be classified into four categories:
regulatory, privacy policies, anonymity, and obfuscation. Following
our quick tour of privacy protection strategies, we dig into some
anonymitybased approaches which use some tricks to fool the
adversaries. We will discuss what kind of protection we can get from
these tricky ideas, and we will make a comparison between these
anonymity-based approaches. At the end of this survey, we provide
several directions of future research on location privacy.
