    • A new class of traceability schemes 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2019)
      Conference report
      Restricted access - publisher's policy
      A new class of tracing traitors schemes with traceability property which combines ideas of nonbinary IPP-codes and IPP set systems is proposed. A detailed comparison of the proposed scheme with previously known traceability ...
    • 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 ...
    • 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 ...
    • 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 ...
    • On non-binary traceability set systems 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2020-03-19)
      Article
      Open Access
      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 ...
    • 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
      Open Access
      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. ...
