presentation: Robustness and Security of Wavelet-Based Watermarking Algorithms
Guest Lecture, Microsoft Research, Cambridge, UK
May 11, 2000
Several wavelet-based watermarking schemes and their
robustness to wavelet compression attacks are discussed. Following an idea
by Fridrich  and experiments by Kundur , we propose to use a
parametrization of wavelet filter coefficients to bring the concept of a
key-dependent transform to the wavelet domain. We demonstrate that the new
technique can be easily intregrated in existing watermarking algorithms to
