Towards Privacy Support in a Global Location Service
Christian Hauser, Matthias Kabatnik · 2001
The fear of services building user profiles will constitute a rising threat to new mobile services. Especially when thinking of location based services, users must be able to trust the system not to misuse their location data. As the number of participants to new location based services will be likely to be very large, a scalable solution for controlling the disclosure as well as the linkage of users’ location data to their identity will be needed. We develop a privacy architecture for a global location service, permitting users exactly to define who will get which granularity of location data as well as identity information. Our architecture reduces necessary trust in the location service and prevents linkage of location queries even without encryption of the whole communication resulting in better performance.
