Digital fingerprinting is a tool to protect multimediarncontent from illegal redistribution by uniquely markingrncopies of the content distributed to each user.rnFingerprinting based on error correction coding (ECC)rnhandle the important issue of how to embed the fingerprintrninto host data in an abstract way known as the markingrnassumptions, which often do not fully account forrnmultimedia specific issues. In this paper, we examine thernperformance of ECC based fingerprinting by consideringrnboth coding and embedding issues. We providernperformance comparison of ECC-based scheme and arnmajor alternative of orthogonal fingerprinting. Asrnaveraging is a feasible and cost-effective collusion attackrnagainst multimedia fingerprints yet is generally notrnconsidered in the ECC-based system, we also investigaternthe resistance against averaging collusion and identifyrnavenues for improving collusion resistance.
