A Blockchain-Based Notarization Service for Biomedical Knowledge Retrieval
(Elsevier Ltd., 2018-08)
Biomedical research and clinical decision depend increasingly on scientific evidence realized by a number of au-thoritative databases, mostly public and continually enriched via peer scientific contributions. Given the ...
Revealing the political affinity of online entities through their Twitter followers
(Elsevier Ltd., 2020-03)
In this work, we show that the structural features of the Twitter online social network can divulge valuable information about the political affinity of the participating nodes. More precisely, we show that Twitter followers ...
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 ...
A Privacy-by-Design Contextual Suggestion System for Tourism
(MDPI, 2016-05-05)
We focus on personal data generated by the sensors and through the everyday usage of smart devices and take advantage of these data to build a non-invasive contextual suggestion system for tourism. The system, which we ...
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 ...
Privacy-Enhanced Television Audience Measurements
(2017-02)
Internet-enabled television systems (SmartTVs) are a development that introduces these devices into the interconnected environment of the Internet of Things. We propose a privacy-preserving application for computing ...
Pythia: A Privacy-enhanced Personalized Contextual Suggestion System for Tourism
(COMPSAC, 2015-07)
We present Pythia, a privacy-enhanced non-invasive contextual suggestion system for tourists, with important architectural innovations. The system offers high quality personalized recommendations, non-invasive operation ...
