ABSTRACT

During the last decade, the digital media placed a vital role in communications due to its wide advantages. As compared with the analog media, digital media is easy to manipulate, High quality streaming over the wide area network (WAN). Therefore, a significant problem of non-authorized copying and distribution of digital media is raised to overcome this problem Digital watermark technique (i.e. embedding a signature signal into image) came into existence. Over the past few years, a number of research papers about reversible watermarks have been produced. Reversible watermarking is a novel category of watermarking schemes. It not only can strengthen the ownership of the original media but also can completely recover the original media from the watermarked media. This feature is suitable for some important media, such as medical and military images, because these kinds of media do not allow any losses. The aim of this paper is to define the purpose of reversible watermarking, reflecting recent progress, and provide some research issues for the future. In this project, a new reversible watermarking scheme is presented. The proposed scheme does need the original image for extracting the watermark, original image and induces not noticeable distortion during the watermarking procedure. The Embedding algorithm has low computational complexity, can be applied to very small images and provides capabilities of multicasting. The basic principle of this scheme is based on the permutations of pixel bins, which are according to a specific rule. For embedding the watermark, a key is needed. Key is a real number that specifies the area where the watermark is to be embedded. Key necessary for decoding message from encoded image. Also a restoration key is created during embedding process, for restoring original image from encoded image both keys are required. Keywords: Imperceptibility, Readily Embedding and Retrieving, Higher Embedding Capacity, Blind, Reversible.
