    • A protocol for data exchange with free samples using smart contracts 

      Genés Durán, Rafael; Hernández Serrano, Juan; Esparza Martín, Óscar; Soriano Ibáñez, Miguel; Muñoz Tapia, José Luis; Bellés Muñoz, Marta (Jornadas de Ingeniería Telemática (JITEL), 2021)
      Text en actes de congrés
      Accés obert
      Distrust between data providers and data consumers is one of the main obstacles hampering digitaldata commerce to take off. Data providers want to get paid for what they offer, while data consumers want to know exactly ...

    • A construction of traceability set systems with polynomial tracing algorithm 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés obert
      A family F of w-subsets of a finite set X is called a set system with the identifiable parent property if for any w-subset contained in the union of some t sets, called traitors, of F at least one of these sets can be ...

    • A new class of traceability schemes 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2019)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A new class of tracing traitors schemes with traceability property which combines ideas of nonbinary IPP-codes and IPP set systems is proposed. A detailed comparison of the proposed scheme with previously known traceability ...

    • Privacy risk analysis in the IoT domain 

      Hernández Serrano, Juan; Muñoz Tapia, José Luis; León Abarca, Olga; Mikkelsen, Lars; Schwefel, Hans-Peter; Bröring, Arne (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      Most IoT systems are using or exchanging user related information between system components. This means that privacy is a key factor in these systems. Privacy, both in terms of not allowing unauthorized access to information, ...

    • Multimedia fingerprinting with noise via signature codes for weighted noisy adder channels and compressed sensing 

      Egorova, Elena; Fernández Muñoz, Marcel; Moon Ho, Lee (2017)
      Text en actes de congrés
      Accés obert
      We propose a new coding scheme for multimedia fingerprinting resistant to noise. Our scheme is based on signature codes for weighted noisy adder channel. The scheme (codes) can trace the entire coalition of pirates and ...

    • Improved existence bounds on IPP codes using the Clique Lovász Local Lemma 

      Aranda, Castor; Fernández Muñoz, Marcel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Nowadays, one of the biggest problems that challenges distributors of digital content is, precisely, protecting such content against redistribution. Those who trade with any of the multiple digital information formats ...

    • On the road to secure and privacy-preserving IoT ecosystems 

      Hernández Serrano, Juan; Muñoz Tapia, José Luis; Bröring, Arne; Esparza Martín, Óscar; Mikkelsen, Lars; Schwarzott, Wolfgang; León Abarca, Olga; Zibuschka, Jan (Springer, 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The Internet of Things (IoT) is on the rise. Today, various IoT platforms are already available, giving access to myriads of things. Initiatives such as BIG IoT are bringing those IoT platforms together in order to form ...

    • Computational improvements in parallelized k-anonymous microaggregation of large databases 

      Mezher, Ahmad Mohamad; Garcia Alvarez, Alejandro; Rebollo Monedero, David; Forné Muñoz, Jorge (2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The technical contents of this paper fall within the field of statistical disclosure control (SDC), which concerns the postprocessing of the demographic portion of the statistical results of surveys containing sensitive ...

    • Códigos de fingerprinting binarios. Nuevos paradigmas de identificación 

      Fernández Muñoz, Marcel; Kabatiansky, Grigory; Egorova, Elena (2016)
      Text en actes de congrés
      Accés obert
      Los códigos con la Identifiable Parent Property garantizan, con probabilidad 1, la identificación de como mínimo de uno de los traidores en sistemas de Traitor Tracing. Desafortunadamente, para el caso de códigos binarios ...

    • A stochastic optimization model for the placement of road site units 

      Urquiza Aguiar, Luis; Tripp Barba, Carolina; Aguilar Igartua, Mónica (Springer, 2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper, we propose a simple and scalable optimization model for the deployment of road site units (RSUs). The model takes advantage of the inherent stochasticity provided by the vehicles’ movements by using mobility ...

    • Almost IPP-codes or provably secure digital fingerprinting codes 

      Fernández Muñoz, Marcel; Kabatiansky, Grigory; Moreira Sánchez, José (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Codes with the Identifiable Parent Property (IPP codes) form a very useful tool in traitor tracing schemes since they guarantee (with probability 1) identification of at least one of the traitors. We consider a natural ...

    • MobilitApp: analysing mobility data of citizens in the metropolitan area of Barcelona
