Abstract. Nowadays, Location Based Services (LBS) are mostly, if not always, based on the processing of location data by two players: the telecommunications service provider and the LBS provider. Assuming that these two players are different entities, we introduce in this paper a viable privacy-enhanced model for LBS based on the concept of a trusted server. Further, we provide technological, legal and economic arguments for this model. We show how to prevent an LBS provider from associating a user to an LBS request in an economically feasible way. We also show how it is possible to prevent, at the same time, the telecommunications service provider from directly associating a specific LBS request with an individual user. 1
