Study on Privacy Aware Location based Service

Abstract

The recent technology drive in communications, positioning and geographical systems opens novel location based applications on current Smart phones. Smart phone users have to disclose their identity to Content Providers to accesses these location based services. In spite of tremendous benefits offered by these apps, User Privacy is compromised. In this survey, we identify a logical structure of grouping the concepts of location privacy. It has been examined the location based services from a broad perspective involving definitions, characteristics, devices, applications and an overview of modeling regarding privacy preserving techniques and privacy metrics. It is concluded that the user privacy is addressed in existing applications and analyzed the factors that assess the efficiency of these privacy techniques under real-world conditions. It further helps researchers to identify open issues in the field of location privacy in LBS.
