Analyzing the information recorded from pervasive sensor networks can provide insight about human behavior for better personalized system services, as well as richer media content and social communication. With these increased capabilities, serious concerns which create great obstacles to the deployment of such network are raised with regard to privacy and boundaries. However, there exist no real data currently about privacy in pervasive media networks and most studies that have been made so far are speculative. This thesis presents the design and implementation of a configurable infrastructure that can protect users' dynamic levels of privacy in a pervasive sensor network. Through an active badge system, users have different options to disable each type of data transmission. This work evaluates approaches for privacy protection through conducting an extensive user study in an actual ubiquitous invasive sensing environment to obtain feedback via sensor system data and questionnaires and correlates that information for future reference in the design of privacy-protected ubiquitous sensor networks. Results from the user study indicated that an active badge for on-site control, especially periodically broadcast RF beacon for privacy control, is the most effective and acceptable method.","abstract_html":"Ubiquitous computing sensor networks have greatly augmented the functionality of interactive media systems by adding the ability to capture and store activity-related information.
