Abdelmgeid A. Ali, Ahmed A. Radwan, Ahmed H. Ismail . Digital Image Watermarking using MSLDIP (Modified Substitute Last Digit in Pixel). International Journal of Computer Applications. 108, 7 ( December 2014), 30-34. DOI=10.5120/18925-0277
The improvements in Internet technologies and growing requests on online multimedia businesses have made digital copyrighting as a significant challenge for businesses that are related with online content distribution via diverse business models including pay-per-view, subscription, trading, etc. Copyright protection and the proof for rightful ownership are major issues related with the distribution of any digital images. Digital watermarking is one of the suggested solutions for copyright protection of multimedia data. This technique is better than Digital Signatures and other methods because it does not rise overhead. In this paper a new watermarking method based on spatial domain image steganography method called MSLDIP (Modified Substitute Last Digit in Pixel) is proposed. The main goal of this method is to hide the watermark in the pixels of digital image in such a manner that the human visual system is not able to distinguish between the cover image and the watermarked image. Also the experimental results showed that this method can be used effectively in the field of watermarking.
