Abstract

In this paper, we focus on improving collusion resistance of error correcting code (ECC) based multimedia fingerprinting. Although permuted subsegment embedding (PSE) scheme has provided better interleaving collusion resistance than conventional scheme, our study shows that the resistance is still weaker than that under averaging collusion at moderate-to-high watermark-to-noise ratio (WNR). We then propose interleaving embedding (ILE) scheme to enforce interleaving collusion resistance, where user's original fingerprint is applied block interleaving before embedded to the host signal. Simulation results show that ILE scheme can resist more colluders' interleaving collusion than PSE scheme at moderate-to-high WNR. Theoretical analysis and experimental results demonstrate that the performance of ECC-based fingerprinting with ILE scheme under interleaving collusion is comparable to that under averaging collusion.
