Pioneering the Technique for Invisible Image Watermarking on Color Image

Accessibility and ease of internet, together with availability of relatively inexpensive digital recording and storage devices has created an environment where duplication, unauthenticated use and maldistribution of digital content has become very easy. This also facilitates unauthorized use, misappropriation, misrepresentation. Thus authentication of multimedia contents (such as image, video, audio) has achieved a sharp attention in recent times. In this perspective we’ve already introduced a framework for invisible image watermarking for color image authentication. In this paper we propose a method for embedding color watermark image to color host image in a more efficient manner. We introduce a new arena of embedding color watermark image at LSB to different positions of color host image in this paper. In proposed watermarking framework, it allows a user with an appropriate secret key and a hash function to verify the authencity, integrity and ownership of an image. We’ve used blind extraction method.
