Privacy for real-time location-based services
Lars Kulik · SIGSPATIAL Special · 2009
Location-Based Services (LBSs) are developing at an amazing pace. Whereas the first generation of LBSs required manual user input of location information via simple web-based interfaces, current GPS-enabled devices such as smartphones or in-car navigation systems can automatically initiate and negotiate LBSs based on their current position. The latest generation of LBSs combines high position accuracy with real-time position updates, which enables numerous applications including asset tracking, location-based advertising, location-sensitive billing, and street-level routing and positioning.
