Location Based Services with Location Centric Profiles

iVu.KOM: A Framework for Viewer-centric Mobile Location-based Services

Users, especially when in unfamiliar areas, would appreciate services that provide them with information about their surroundings and objects in the neighborhood. A natural way to find such information is by looking at the objects. Therefore, it would be very useful if Location-based Services could provide a kind of viewer-centric interaction between the users and their surroundings. In this pa...

Location Depersonalization for Location Privacy Protection in Location-Based Services

A spatial region with K different footprints indicates that it has been visited by K different people. An adversary may be able to identify all these users, but will not know who was there at what time. This observation gives us a new direction to investigate location depersonalization in location-based services (LBSs). We propose to leverage users’ historical location samples, each being a foo...

Over the past ten years location-based services (LBS) have been variously touted as the next generation of GIS; as the killer application that will bring the GIS industry to its next level of prosperity; and as a growing threat to human privacy. This chapter attempts to provide a basic introduction to LBS, and a discussion of some of the major issues surrounding them. It begins with basic defin...

Since the value for the users depends on the context (i.e. environmental factors surrounding them), mobile services can be assigned to different context-aware services which are characterized by integrating information about the us...
