Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (Institute of Electrical and Electronics Engineers (IEEE), 2019)
Text en actes de congrés
Accés obertA family F of w-subsets of a finite set X is called a set system with the identifiable parent property if for any w-subset contained in the union of some t sets, called traitors, of F at least one of these sets can be ... -
A family of asymptotically good binary fingerprinting codes
Cotrina Navau, Josep; Fernández Muñoz, Marcel (2010-10)
Article
Accés restringit per política de l'editorialA 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 ... -

Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel; Cotrina Navau, Josep (Springer, 2005)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 new class of traceability schemes
Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2019)
Text en actes de congrés
Accés restringit per política de l'editorialA 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 ... -
A note about the traceability properties of linear codes
Fernández Muñoz, Marcel; Cotrina Navau, Josep; Soriano Ibáñez, Miguel; Domingo, Neus (Springer, 2007)
Text en actes de congrés
Accés restringit per política de l'editorialWe 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 ... -
A novel support recovery algorithms and its applications to multiple-access channels
Fernández Muñoz, Marcel; Kabatiansky, Grigory; Miao, Ying (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialA novel algorithm of a sparse vector support recovery in presence of noise is proposed. In contrary to known algorithms based on matrices with RIP-property our algorithm exploits properties of so-called separating codes. ... -
A study of the separating property in Reed-Solomon codes by bounding the minimum distance
Fernández Muñoz, Marcel; Jiménez Urroz, Jorge (2022-02)
Article
Accés obertAccording to their strength, the tracing properties of a code can be categorized as frameproof, separating, IPP and TA. It is known that, if the minimum distance of the code is larger than a certain threshold then the TA ... -
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'editorialCodes 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)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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
Accés obertIn 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)
Text en actes de congrés
Accés restringit per política de l'editorialSecure 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
Accés obertThis 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 ... -
