摘要：Now a days, due to sharp rise in the Internet services, the critical issue of copyright protection of document content increases.Watermarking is a way of providing protection for ownership on owner's document. To enlarge security of copyright protection and to produce indistinguishable watermarked image from original cover image with human eye, a new watermarking approach using diagonally pixel value differencing in a segment during embedding and extraction with a proposed range table is proposed in this paper. The experimental results show that the proposed method is highly efficient for providing more secure ownership on his/her document and also the proposed method is secured against effects of attacks. Besides, the embedded original watermark can be extracted from watermarked image without the assistance of original cover image.
