    k-Anonymous microaggregation is a widespread technique to address the problem of protecting the privacy of the respondents involved beyond the mere suppression of their identifiers, in applications where preserving the ...
  • Knowledge sharing in the health scenario 

    LLuch Ariet, Magi; Brugues de la Torre, Albert; Vallverdú Bayés, Sisco; Pegueroles Vallés, Josep R. (2014-11-28)
    Article
    Open Access
    The understanding of certain data often requires the collection of similar data from different places to be analysed and interpreted. Interoperability standards and ontologies, are facilitating data interchange around the ...
  • Incremental k-Anonymous microaggregation in large-scale electronic surveys with optimized scheduling 

    Rebollo Monedero, David; Forné Muñoz, Jorge; Soriano Ibáñez, Miguel; Hernández Baigorri, César (Institute of Electrical and Electronics Engineers (IEEE), 2018-10-15)
    Article
    Open Access
    Improvements in technology have led to enormous volumes of detailed personal information made available for any number of statistical studies. This has stimulated the need for anonymization techniques striving to attain a ...
  • Constructions of almost secure frameproof codes with applications to fingerprinting schemes 

    Moreira, Jose; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2018-04)
    Article
    Open Access
    This paper presents explicit constructions of fingerprinting codes. The proposed constructions use a class of codes called almost secure frameproof codes. An almost secure frameproof code is a relaxed version of a secure ...
  • Transient analysis of idle time in VANETs using Markov-reward models 

    Martín Faus, Isabel Victoria; Urquiza Aguiar, Luis; Aguilar Igartua, Mónica; Guérin-Lassous, Isabelle (2018-02-10)
    Article
    Open Access
    The development of analytical models to analyze the behavior of vehicular ad hoc networks (VANETs) is a challenging aim. Adaptive methods are suitable for many algorithms (e.g., choice of forwarding paths, dynamic resource ...
  • Game-theoretical design of an adaptive distributed dissemination protocol for VANETs 

    Iza Paredes, Cristhian; Mezher, Ahmad Mohamad; Aguilar Igartua, Mónica; Forné Muñoz, Jorge (Multidisciplinary Digital Publishing Institute (MDPI), 2018-01-01)
    Article
    Open Access
    Road safety applications envisaged for Vehicular Ad Hoc Networks (VANETs) depend largely on the dissemination of warning messages to deliver information to concerned vehicles. The intended applications, as well as some ...
  • On the anonymity risk of time-varying user profiles. 

    Puglisi, Silvia; Rebollo Monedero, David; Forné Muñoz, Jorge (2017-04-26)
    Article
    Open Access
    Websites and applications use personalisation services to profile their users, collect their patterns and activities and eventually use this data to provide tailored suggestions. User preferences and social interactions ...
  • On web user tracking of browsing patterns for personalised advertising 

    Puglisi, Silvia; Rebollo Monedero, David; Forné Muñoz, Jorge (2017-02-19)
    Article
    Open Access
    On today’s Web, users trade access to their private data for content and services. App and service providers want to know everything they can about their users, in order to improve their product experience. Also, advertising ...
  • p-probabilistic k-anonymous microaggregation for the anonymization of surveys with uncertain participation 

    Rebollo Monedero, David; Forné Muñoz, Jorge; Soriano Ibáñez, Miguel; Puiggalí Allepuz, Jordi (2016-12-13)
    Article
    Open Access
    We develop a probabilistic variant of k-anonymous microaggregation which we term p-probabilistic resorting to a statistical model of respondent participation in order to aggregate quasi-identifiers in such a manner that ...
  • Shall I post this now? Optimized, delay-based privacy protection in social networks 

    Parra Arnau, Javier; Gómez Mármol, Félix; Rebollo Monedero, David; Forné Muñoz, Jorge (2016-11-16)
    Article
    Open Access
    Despite the several advantages commonly attributed to social networks such as easiness and immediacy to communicate with acquaintances and friends, significant privacy threats provoked by unexperienced or even irresponsible ...
  • Almost separating and almost secure frameproof codes over q-ary alphabets 

    Moreira Sánchez, José; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2015-03-27)
    Article
    Open Access
    In this paper we discuss some variations of the notion of separating code for alphabets of arbitrary size. We show how the original definition can be relaxed in two different ways, namely almost separating and almost secure ...
