  • 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 ...

    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 ...
