Abstract:
Scaling attacks are well-known to be some of the most harmful strategies against quantization-based watermarking methods, as they can completely ruin the performance of the watermarking system with almost no perceptual impact on the watermarked signal. In this paper we propose a new family of quantization-based methods specifically devised to deal with those attacks, and which presents the desirable property of yielding perceptually shaped watermarks.
