Location-based Services (LBSs) are mobile services for providing information that has been created, compiled, selected or filtered under consideration of the usersa€™ current locations or those of other persons or mobile devices. Typical examples are restaurant finders, buddy trackers, navigation services or applications in the areas of mobile marketing and mobile gaming.
