  • A family of asymptotically good binary fingerprinting codes 

    Cotrina Navau, Josep; Fernández Muñoz, Marcel (2010-10)
    Article
    Restricted access - publisher's policy
    A fingerprinting code is a set of codewords that are embedded in each copy of a digital object with the purpose of making each copy unique. If the fingerprinting code is c-secure with error, then the decoding of a pirate ...
  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Almost separating and almost secure frameproof codes 

    Fernández Muñoz, Marcel; Kabatiansky, Grigory; Moreira Sánchez, José (2011)
    Conference report
    Restricted access - publisher's policy
    The theory of separating codes has been applied in several areas of science ranging from automata synthesis to the protection of distribution rights. In this paper, we introduce a relaxed version of separating and secure ...
  • 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 ...
  • A new class of codes for fingerprinting schemes 

    Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel; Cotrina Navau, Josep (Springer, 2005)
    Conference report
    Restricted access - publisher's policy
    In this paper we discuss the problem of collusion secure fingerprinting. In the first part of our contribution we prove the existence of equidistant codes that can be used as fingerprinting codes. Then we show that by ...
  • A note about the traceability properties of linear codes 

    Fernández Muñoz, Marcel; Cotrina Navau, Josep; Soriano Ibáñez, Miguel; Domingo, Neus (Springer, 2007)
    Conference report
    Restricted access - publisher's policy
    We characterize the traceability properties of linear codes. It is well known that any code of length n and minimum distance d is a c-TA code if c 2¿<¿n/(n¿-¿d). In this paper, we show that a less restrictive condition can ...
  • Códigos de fingerprinting binarios. Nuevos paradigmas de identificación 

    Fernández Muñoz, Marcel; Kabatiansky, Grigory; Egorova, Elena (2016)
    Conference report
    Open Access
    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 ...
  • Constructions of almost secure frameproof codes based on small-bias probability spaces 

    Moreira Sánchez, José; Fernández Muñoz, Marcel; Kabatiansky, Grigory (Springer International Publishing, 2013)
    Conference report
    Restricted access - publisher's policy
    Secure frameproof code is the name given to a separating code when studied in relation to fingerprinting schemes. Separating codes are combinatorial objects that have found to be useful in many areas such as technical ...
  • 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 ...
  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • 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)
    Conference report
    Restricted access - publisher's policy
    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)
    Conference report
    Open Access
    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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Parallelization of the interpolation process in the Koetter-Vardy soft-decision list decoding algorithm 

    Moreira Sánchez, José; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (2012)
    Conference lecture
    Open Access
    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 ...
  • Tracing traitors by guessing secrets. The q-ary case 

    Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel; Cotrina Navau, Josep (Springer, 2005)
    Conference report
