Description

With the rapid growth of high speed computer network and that of internet reproduction and distribution of digital data has become easier than ever before. Due to the open environment of internet downloading, new set of challenging problems is introduced in copyright protection regarding security and illegal distribution of privately owned images. Digital watermarking techniques have been proposed to solve the ownership problem about how to authenticate the digital data. The aim of this book is to make students and professionals aware about how to combine both cryptography and digital watermarking together for embedding the secret information to achieve higher secrecy and efficiency. In this book digital watermarking embedding scheme and extraction scheme are proposed using Data Encryption Standard (DES) based on spatial domain for gray scale and colour images. These proposed schemes were evaluated using the following metrics: Peak Signal to Noise Ratio (PSNR), Normalized Cross Correlation (NCC) and Image Histograms, along with the various Noises. In this book MATLAB codes were provided for better understanding for beginners.
