In our research, we design a lossless visible watermarking scheme whichcan extract the original visible watermark and recover the original hostmage losslessly. Our research based on reversible data-hiding techniques to embed secret data at unwatermarked area. At watermarked area, we replace the LSB7 by halftone watermark. The experimental result shows that PSNR values of watermarked images from our scheme are better than ones obtained from previous schemes; also we can see the watermark clearly.
