Abstract
In this paper, we propose an approach to improve the performance of a broad class of watermarking schemes through attack characterization. Robust and reference watermarks are both embedded into a signal. The reference watermark is used to characterize any modifications of the resulting marked signal, so that the robust watermark can be more reliably extracted. Analysis and simulations are provided to demonstrate the effectiveness of the approach.
