    • 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 ...

      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 ...

      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 ...

      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 ...

      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 ...
