    • 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 ...
