Transparent Image Watermarking in the Wavelet Domain

引用

Wuhan University Journal of Natural Sciences 2000年第4期5卷 457-460页

作者： Chen Qing, Su xiang-fang, wang Yan-ping College of Electronic Information, Wuhan University, Wuhan 430072, China College of Electronic Information Wuhan University Wuhan China

Digital watermarking has been proposed as a viable solution to protect the copyright of multimedia data in a networked environment, since it makes possible to embed identification codes into a digital document. This paper proposes a new scheme for image watermarking in which a watermark is embedded in a selected set of wavelet transform coefficients. To ensure the watermark invisibility with high robustness, a binary pseudo-random sequence is embedded into significant wavelet coefficients by exploiting Embedded Zerotree Wavelet (EZW) coding algorithm. Experimental results show the effectiveness of this technique.
