Abstract :
The enhanced data processing technologies have made the manipulation and computation of digital data & images easier. This has created a need for the copyright protection of digital content. In this paper a novel reversible visible watermarking algorithm is proposed to cater the needs of copyright protection and to resume the original image data processing at the receiver´s end. This proposed algorithm uses a noise sensitive region based watermarking embedding (NSRBWE) technique to embed the watermark W in the given region R of Image I. To extract the original image from the visible watermarked image it is necessary to remove the full watermark. We preserve the information of altered pixels of the region R in the rest of image I - R. Our algorithm can fully remove the watermark from the visible watermarked image. It uses a Secret Key K to reconstruct the altered pixels value. In addition, only users with correct secret key K can restore the original image.
