For the mobile computing environment, binding the cyberworld to the real world is an important service. We have developed a geographical location information (GLI) system that binds a logical location of network entities to its geographical location information. Privacy control in the GLI system is important. In this paper, we propose a privacy control scheme for our GLI system. The scheme provides the following capabilities:
1) manage public and private information at once
2) protect private information from illegal user access
3) access private information without direct communication with the owner
We are implementing a prototype GLI system with a privacy control mechanism. A preliminary evaluation of the prototype system is also given.
