Identification algorithms for sequential traitor tracing

Abstract

Sequential traitor tracing schemes [10, 11] are generally used to deter piracy in multimedia content delivery scenarios. This is accomplished by embedding the codewords of a code with traceability properties into the content, prior to its delivery. The focus of this paper is on tracing algorithms for sequential traitor tracing schemes, where soft-decision list decoding techniques are applied in order to improve the identification process in the original sequential traitor tracing schemes, where where a brute force approach is used. © Springer-Verlag 2004.
