A Novel Framework for Privacy Preserving in Location Based Services

As availability of the mobile has been increased and many providers have started offering Location Based Services (LBS). There is undoubted potential of location-aware computing, but location awareness also comes up with the inherent threats, perhaps the most important of which is location privacy. This tracking of the location information result into unauthorized access of location data of user and causes serious consequences. It is a challenge to develop effective security schemes which can allow users to freely navigate through different applications, services and also ensure that the user´s private information cannot be revealed elsewhere. This paper presents a detailed overview of existing schemes applied to Location Based Services (LBS). It also proposes a novel privacy preserving method (based on PIR) to provide the location privacy to the user.
