The Security And Privacy Implications Of Energy-Proportional Computing, Shane S. Clark
The Security And Privacy Implications Of Energy-Proportional Computing, Shane S. Clark
Open Access Dissertations
The parallel trends of greater energy-efficiency and more aggressive power management are yielding computers that inch closer to energy-proportional computing with every generation. Energy-proportional computing, in which power consumption scales closely with workload, has unintended side effects for security and privacy. Saving energy is an unqualified boon for computer operators, but it is becoming easier to identify computing activities by observing power consumption because an energy-proportional computer reveals more about its workload.
This thesis demonstrates the potential for system-level power analysis---the inference of a computers internal states based on power observation at the "plug." It also examines which hardware components …

Exploring Privacy And Personalization In Information Retrieval Applications, Henry A. Feild
Open Access Dissertations
A growing number of information retrieval applications rely on search behavior aggregated over many users. If aggregated data such as search query reformulations is not handled properly, it can allow users to be identified and their privacy compromised. Besides leveraging aggregate data, it is also common for applications to make use of user-specific behavior in order to provide a personalized experience for users. Unlike aggregate data, privacy is not an issue in individual personalization since users are the only consumers of their own data.
The goal of this work is to explore the effects of personalization and privacy preservation methods …
