An interleaving-decomposition based digital watermarking scheme in wavelet domain

A new digital watermarking scheme, which combines interleaving-decomposition and DWT, is proposed in this paper. Similar to scrambling, interleaving-decomposition is used to enhance the robustness of the watermark. First, according to interleaving-decomposition theory, the watermark image and the wavelet coefficients of the original image are decomposed into two sequences respectively. Then the decomposed watermark is embedded into the corresponding significant wavelet coefficients. Experimental results demonstrate that the proposed scheme has good robustness to the common hostile attack, such as JPEG compression, median filtering, adding noise, etc
