A collaborative protocol for anonymous reporting in vehicular ad hoc networks
(Elsevier, 2013-11-01)
Article
Restricted access - publisher's policyVehicular ad hoc networks (VANETs) have emerged to leverage the power of modern communication technologies, applied to both vehicles and infrastructure. Allowing drivers to report traffic accidents and violations through ... -
A Collaborative Protocol for Private Retrieval of Location-Based Information
(IADIS Press, 2009)
Conference lecture
Open AccessPrivacy and security are paramount for the proper deployment of location-based services (LBSs). We present a novel protocol based on user collaboration to privately retrieve location-based information from an LBS provider. ... -
An Algorithm for k-Anonymous Microaggregation and Clustering Inspired by the Design of Distortion-Optimized Quantizers
(Elsevier Science Ltd., 2011)
Article
Restricted access - publisher's policyWe present a multidisciplinary solution to the problems of anonymous microaggregation and clustering, illustrated with two applications, namely privacy protection in databases, and private retrieval of location-based ... -
A privacy-preserving architecture for the semantic web based on tag suppression
(Springer, 2010)
Conference report
Restricted access - publisher's policyWe propose an architecture that preserves user privacy in the semantic Web via tag suppression. In tag suppression, users may wish to tag some resources and refrain from tagging some others in order to hinder privacy ... -

A privacy-protecting architecture for collaborative filtering via forgery and suppression of ratings
(Springer, 2011)
Conference report
Restricted access - publisher's policyRecommendation systems are information-filtering systems that help users deal with information overload. Unfortunately, current recommendation systems prompt serious privacy concerns. In this work, we propose an architecture ... -

Building hierarchical public key infrastructures in mobile ad-hoc networks
(Springer, 2006)
Conference report
Restricted access - publisher's policyDynamism of mobile ad-hoc networks implies changing trust relationships among their nodes that can be established using peer-to-peer PKIs. Here, certification paths can be built although part of the infrastructure is ... -
Categorization of bibsonomy tags to apply privacy-preserving mechanisms.
(2012-07-24)
Other
Open AccessIn this technical report, we approach one of the practical aspects when it comes to represent users' interests from their tagging activity, namely the categorization of tags into high-level categories of interest. The ... -
Certificate revocation system implementation based on the Merkle Hash Tree
(2004-01)
Article
Restricted access - publisher's policyPublic-key cryptography is widely used to provide Internet security services. The public-key infrastructure (PKI) is the infrastructure that supports the public-key cryptography, and the revocation of certificates implies ... -
CERVANTES - A certificate validation test-bed
(Springer Berlin / Heidelberg, 2004)
Conference report
Restricted access - publisher's policyCertificate validation is one of the toughest scalability problems of the PKI. The goal of this paper is to introduce a Java platform for certificate revocation called CERVANTES. CERVANTES pretends to be an easy to extend ... -

Digital hyper-transparency: leading e-government against privacy
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessFor a long time, the Internet and web technologies have supported a more fluid interaction between public institutions and citizens through e-government. With this spirit, several public services are being offered online. ... -
Does k-anonymous microaggregation affect machine-learned macrotrends?
(Institute of Electrical and Electronics Engineers (IEEE), 2018-05-16)
Article
Open Accessn the era of big data, the availability of massive amounts of information makes privacy protection more necessary than ever. Among a variety of anonymization mechanisms, microaggregation is a common approach to satisfy the ... -
