Sliding-window dynamic frameproof codes
نویسنده
چکیده
A sliding-window dynamic frameproof code is a scheme for discouraging the piracy of digital broadcasts through the use of digital fingerprinting. In this paper we formally define sliding-window dynamic frameproof codes and provide optimal constructions for a certain class of these schemes. We also discuss bounds on the number of users such schemes

Dynamic frameproof codes
There are many schemes in the literature for protecting digital data from piracy by the use of digital fingerprinting, such as frameproof codes, which prevent traitorous users from colluding to frame an innocent user, and traitortracing schemes, which enable the identification of users involved in piracy. The concept of traitor tracing has been applied to a digital broadcast setting in the form...
متن کاملSequential and dynamic frameproof codes
There are many schemes in the literature for protecting digital data from piracy by the use of digital fingerprinting, such as frameproof codes and traitor-tracing schemes. The concept of traitor tracing has been applied to a digital broadcast setting in the form of dynamic traitor-tracing schemes and sequential traitor-tracing schemes, which could be used to combat piracy of pay-TV broadcasts,...
متن کاملOn symmetric designs and binary 3-frameproof codes
In this paper, we study when the incidence matrix of a symmetric (v, k, λ)-BIBD is a 3-frameproof code. We show the existence of infinite families of symmetric BIBDs that are 3-frameproof codes, as well as infinite families of symmetric BIBDs that are not 3-frameproof codes.
متن کاملCombinatorial Properties and Constructions of Traceability Schemes and Frameproof Codes
In this paper we investigate combinatorial properties and constructions of two recent topics of cryptographic interest namely frameproof codes for digital ngerprinting and traceability schemes for broadcast encryption We rst give combinatorial descriptions of these two objects in terms of set systems and also discuss the Hamming distance of frameproof codes when viewed as error correcting codes...
متن کاملOn Collusion Security of Random Codes
Fingerprinting is a technique to add identifying marks to each copy of digital contents in order to enhance traceability to a distribution system. Collusion attacks, in which the attackers collect two or more fingerprinted copies and try to generate an untraceable copy, are considered to be a threat for the fingerprinting system. With the aim of enhancing collusion security to the fingerprintin...
