Workshop on Ubicomp Communities: Privacy as Boundary Negotiation, in International Conference on Ubiquitous Computing (Ubicomp)


January 2003


Privacy concerns remain a major barrier to adoption of location-based services. Users demand significant, concrete benefits before they are willing to allow an outside party to track their movements. We propose Place Lab, a trustworthy, secure location infrastructure that gives users control over the degree of personal information they release. Place Lab allows service providers to design services that provide basic benefits to all users, and expanded benefits as users release personal location information. This position paper discusses privacy and security issues arising in Place Lab, a multi-organization initiative to bootstrap the location-enhanced web.
