Enhancing Deniability against Query-Logs
(Springer, 2011)
We propose a method for search privacy on the Internet, focusing onenhancing plausible deniability against search engine query-logs. The method ap-proximates the target search results, without submitting the intended query ...
A privacy-preserving cloud computing system for creating participatory noise maps
(IEEE, 2012)
Participatory sensing is a crowd-sourcing technique which relies both on active contribution of citizens and on their location and mobility patterns. As such, it is particularly vulnerable to privacy concerns, which may ...
PHUBMIT - A new smart intervention for estimating and mitigating the cell phone induced ostracism (phubbing)
