| Summary: | Sensor deployments are becoming more and more common nowadays and the ways to access them are becoming more standardized. Indeed, users want to access sensor data via the Internet and without using some complex and unknown protocol; enter Web Services. By observing the typical system architecture for relaying sensor information to the web, we identified out of a large group of security issues a particular one. The issue in question is user privacy. In this thesis we focus on hiding the activity of a user who queries a sensor deployment, from an attacker that can listen to communications in the neighborhood of the network. Our goal is to generate extra traffic in an intelligent way so that it can effectively mask user activity without draining the energy from the sensors. |
