LOCAL DECISION POLICIES ABOUT THE SHARING OF SENSED DATA THAT ENHANCE PRIVACY AND LOWER COMMUNICATION COSTS FOR SERVICES THAT AGGREGATE DATA FROM PERSONAL DEVICES |
摘要 |
Velocity information can be beneficial to various entities including other vehicles and a central traffic monitoring and routing system. Vehicles with sensors can serve as velocity probes to update speeds that are shared via a more global service. However, individuals may be reluctant to provide location and velocity information given privacy preferences. Local policies about sharing personal data are described that can be harnessed to enhance privacy while minimizing communication costs. The local data-sharing policies allow devices to monitor their own speeds and locations and to employ models and analyses that determine the value of sharing flow information with a larger service in accordance with privacy preferences, and to make local decisions as to when to respond to broadcasted queries for specific information, while minimizing the redundancy of signals from multiple vehicles. |
