Abstract
A novel digital watermarking technique for color images using magic square and ridgelet transforms is designed, developed, tested, and described in this book. The novel feature of the method is to generate and use multiple copies of the digital watermark. This is tested for embedding digital watermark into color cover images and resulted in very high PSNR value and yielded comparable results with existing watermarking techniques. The book also deals with fractal coding technique for enhancing the robustness of the watermark techniques. Six different techniques are designed, developed, and tested leading to the technique using magic square and ridgelets. Two other techniques are designed, developed, and tested using fractals. Chapter 1 discusses the fundamentals of digital water
