A robust deinterlacing multiple image Watermarking technique in DWT

Abstract

Digital Watermarking has been used as a tool to protect the Intellectual Property Rights of multimedia documents. Through the watermarking we are able to prevent the unauthorized access, modification, and alteration of digital multimedia document. In today's era distribution of digital documents and e-commerce are widely used. Problem of Intellectual and copyright protection can be solved through multiple watermarking. In Multiple Watermarking we can insert more than one watermark into Multimedia content, to accomplish various goals of Digital Watermarking. In our proposed method we are focusing on the robustness, imperceptibility and capacity of watermark in frequency domain against unintentional and intentional signals/distortion. We apply deinterlacing process on the sub band of host image according to its even and odd row pixel value. On these deinterlaced images we insert our visible binary watermark. For insertion of watermark we are using additive watermark insertion technique. Proposed method is a trade-off between the elements of watermarking requirement triangle.
