Today's location-sensitive service relies on user's mobile device to determine its location and send the location to the application. A location-based service is a service that determines the location of a mobile device and uses this to provide functionalities and information specific to that location. With the growth of the importance and of the audience of location-based services, questions of security and privacy are brought forward. As services are being built on top of this technology, the number of parties increases significantly, and the possibility of a malicious insider (or a misbehaving insider) emerges. The extent to which the parties care to trust each other has reduced, and trust amongst the various parties can no longer be assumed by a location-based service.
