This book presents improved Digital watermarking is a process to embed the secret information into digital data for verifying an identity of the owners by making the assertion about the data and image authentication applications that provide security to watermark, W which is converted to a sequence of random binary R of size n adopted to encrypt the watermark. The digital watermarking is created as a method to solve this kind of problems. There are two issues which are embedded watermark image in the host image without causing any kind of degradation, achieve and improve both imperceptibility and robustness of watermarked image before and after attacks. In this book, The RGB colour image watermarking is proposed using by Discrete Slantlet Transform (DST) to generate a higher degree of robustness and imperceptibility of the watermarked image. After applying 2-level DST on the host image to divided Red, Green and Blue select the best channel to embedding.
