In this paper, we introduce a novel signal-dependent parameterization of Slant-Hadamard transform. A secure watermarking scheme in transform domain is proposed based on this new orthonormal transform. Then watermarking performance is analyzed and discussed if we model the watermarking scheme as spread spectrum communication problem. We also propose an optimal parameters selection algorithm and show the robustness performance of the method through simulations that compare with watermarking approaches in other orthogonal domains in the presence of lossy compression.
