Location Privacy: Who Knows Where You Are?

Engineering advances, like precise and accurate personal positioning systems, are helping to enable a wide range of commercially and socially beneficial information services. In this context, location privacy (the right of individuals to control information about their personal location) can seem a peripheral or puzzling issue for many engineers. As one engineering colleague put it to me: “If you have nothing to hide, why should you be concerned about location privacy?” However, location privacy is increasingly becoming a vital function of any location-based service, and a function that presents spatial information engineers with interesting new challenges.
