Reversible Watermarking Method for JPEG Images

open access: yesIEICE Transactions on Information and Systems, 2008
In this letter, we propose a simple reversible watermarking method for JPEG images using the characteristics of JPEG compression. The method embeds a watermark into a JPEG image, and it extracts the watermark from the watermarked JPEG image and at the same time can recover the watermarked JPEG image to an original unwatermarked JPEG image.
