Projects

PriLoc — Privacy-aware Location Management

Funded by: German Research Foundation (DFG)

The PriLoc Project is focused on concepts and algorithms for the secure management of private position information in non-trusted location server infrastructures, e.g., Cloud computing infrastructures of different providers. Typically, advanced location-based applications such as friend finders or geo-social networks are based on location server infrastructures storing mobile user positions to ensure scalability by enabling the sharing of user positions between multiple applications. However, storing data on location servers raises privacy concerns if the user does not trust the provider of the location service. Multiple incidents in the past have shown that even if the provider is not misusing the data himself, private information can be revealed due to attacks, leaking, or loss of data. Therefore, the assumption of a trusted location service is questionable, and technical concepts are required to ensure location privacy without requiring a trusted third party.

The PriLoc Project investigates such concepts for the secure management of private position information on non-trusted location server infrastructures. In particular, we designed a novel position sharing approach with interesting properties such as no single point of failure w.r.t. privacy, graceful degradation of privacy with the number of compromised servers, and support of different, individual precision levels for location-based applications with different quality demands and trust levels.
