摘要
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, then the decoding of a pirate word created by a coalition of at most c dishonest users, will expose at least one of the guilty parties. In this paper we construct a 2-secure fingerprinting code by concatenating an inner (2,2)-separating code with an outter IPP code. The particular choice of the codes is such that allows the use of efficient decoding algorithms that correct errors beyond the error correction bound of the code, namely a simplified version of the Chase algorithms for the inner code and the Koetter-Vardy soft-decision list decoding algorithm for the outter code.
