Digital watermarking is widely used to protect the copyright of digital media. The watermarking approach is usually to embed a copyright mark into the target media to claim the ownership. Any ownership dispute can be judged by detecting the existence of the copyright mark. In the paper, we propose a reversible visible watermark method, which embeds binary-imaged watermark into gray-scale images to create a visible watermark. Not using complex calculations, this paper tries to simply change the pixel value to achieve the digital watermark. Besides, a reversible steganographic method is used to embed the watermark information into the watermarked images. The watermark information can be used to recover the original images.
