Novel DCT based watermarking scheme for digital images

چکیده
There is an ever growing interest in copyright protection of multimedia content, thus digital watermarking techniques are widely practiced. Due to the internet connectivity and digital libraries the research interest of protecting digital content watermarking is extensively researched. In this paper we present a novel watermark generation scheme based on the histogram of the image and apply it to the original image in the transform(DCT) domain. Further we study the performance of the watermark against some common attacks that can take place with images. Experimental results show that the embedded watermark is imperceptible and image quality is not degraded.
