Location based services (LBS) are distributed multi-party infrastructures with the opportunity to generate profitable m-business applications. Also, LBS pose a great risk for their users' privacy, as they have access to private information about a person's whereabouts in a particular context. As location data is the essential input for LBS, protection of privacy in LBS is not a problem of providing anonymity by supressing data release, but a problem of identity management and control over information handling. In this paper we show a solution that ensures a LBS user's control over location information with managed identities. At the same time, our solution enables profitable business models, e.g. for mobile telephony operators. Additionally, we provide fine-grained consent management for the LBS user.
