Digital Watermarking on Multimedia Application

Digital Watermarking Schemes for Multimedia Authentication

Digital Watermarking for Multimedia Security Management

This chapter is intended to disseminate the concept of digital watermarking for multimedia security management in general, and multimedia copyright protection and content integrity verification in particular. We will be addressing the challenges posed to multimedia security management and how digital watermarking can be deployed in different applications in order to meet those challenges. Categ...

A Robust Digital Image Watermarking Scheme Based on DWT

In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

A Short Summary of Digital Watermarking Techniques for Multimedia Data

The growth of networked multimedia systems has created the need for the copyright protection of various digital medium, e.g., images, audio clips, video, etc. Copyright protection involves the authentication of ownership and the identi cation of illegal copies of a (possibly forged) image. One approach used to address this problem is to add a visible or invisible structure to an image that can ...
