Protecting People Location Information ( Extended
نویسنده
چکیده
Ubiquitous computing environments rely on the availability of location information about people to provide location-specific services. However, location is a sensitive piece of information. For example, it is often possible to gather information about the current activities of a person from her location. Therefore, location information should not be distributed to just anyone. The solution is to allow people to specify location policies that state who should be allowed to locate them. In this paper, we present and motivate key features that should be supported by location policies. We have implemented a prototype of a secure people location service that supports many of the features discussed here, and we are currently evaluating the system with real users in the context of the CMU Aura project [1].
