Privacy-preserving computation of participatory noise maps in the cloud
(Elsevier Ltd., 2014-06)
This paper presents a privacy-preserving system for participatory sensing, which relies on cryptographic techniques and distributed computations in the cloud. Each individual user is represented by a personal software ...
User-Centric Privacy-Preserving Statistical Analysis of Ubiquitous Health Monitoring Data
(ComSIS Consortium, 2014)
In this paper, we propose a user-centric software architecture for managing Ubiquitous Health Monitoring Data (UHMD) generated from wearable sensors in a Ubiquitous Health Monitoring System (UHMS), and examine how these ...
A query scrambler for search privacy on the internet
(Springer Link, 2012-10-09)
We propose a method for search privacy on the Internet, focusing on enhancing plausible deniability against search engine query-logs. The method approximates the target search results, without submitting the intended query ...
An efficient privacy-preserving solution for finding the nearest doctor
(Personal and Ubiquitous Computing volume, 2012-10-30)
In this work, we define the Nearest Doctor Problem for finding the nearest doctor in case of an emergency and present a privacy-preserving protocol for solving it. The solution is based on cryptographic primitives and makes ...
Versatile Query Scrambling for Private Web Search
(Springer Link, 2015-05-16)
We consider the problem of privacy leaks suffered by Internet users when they perform web searches, and propose a framework to mitigate them. In brief, given a ‘sensitive’ search query, the objective of our work is to ...
