    • Multimedia copyright protection platform demonstrator 

      Soriano Ibáñez, Miguel; Fernández Muñoz, Marcel; Sayrol Clols, Elisa; Tomás Buliart, Joan; Casanellas, Joan; Pegueroles Vallés, Josep R.; Hernández Serrano, Juan (Springer, 2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The work presented in this paper consists in the development of a portable platform to protect the copyright and distribution rights of digital contents, and empirically demonstrate the capacity of several marking and ...

    • 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 ...

    • New considerations about the correct design of turbo fingerprinting codes 

      Tomás Buliart, Joan; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (Springer, 2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Since the introduction of turbo codes in 1993, many new applications for this family of codes have been proposed. One of the latest, in the context of digital fingerprinting, is called turbo fingerprinting codes and was ...

    • On non-binary traceability set systems 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2020-03-19)
      Article
      Accés obert
      We introduce non-binary IPP set systems with traceability properties that have IPP codes and binary IPP set systems with traceability capabilities as particular cases. We prove an analogue of the Gilbert–Varshamov bound ...

    • Parallelization of the interpolation process in the Koetter-Vardy soft-decision list decoding algorithm 

      Moreira Sánchez, José; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (2012)
      Comunicació de congrés
      Accés obert
      List decoding is a decoding strategy that provides a set of codewords at the output of the channel decoder. Since this technique corrects errors beyond the correcting bound of the code, upper layers in the application or ...

    • Signature codes for weighted noisy adder channel, multimedia fingerprinting and compressed sensing 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory; Moon Ho, Lee (2019-03-01)
      Article
      Accés obert
      We propose a new approach to construct noise-resistant multimedia fingerprinting codes. Our approach is based on the theory of the signature codes for multiple access channels, mainly, for a weighted noisy adder channel. ...

    • Tracing traitors by guessing secrets. The q-ary case 

      Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel; Cotrina Navau, Josep (Springer, 2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper we present, by solving a variant of the guessing secrets problem defined by Chung, Graham and Leighton [3], a sequential traitor tracing scheme equipped with an efficient identification algorithm. Sequential ...

    • Use of Turbo Codes with Low-Rate Convolutional Constituent Codes in Fingerprinting Scenarios 

      Tomás Buliart, Joan; Gómez Muro, Ana; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (IEEE, 2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      We discuss the use of turbo codes in fingerprinting schemes. More precisely, we present a family of turbo codes that are secure against attacking coalitions of size 2. This family is build upon a class of low-rate convolutional ...
