Digital image watermarking has gained a huge interest among researchers in the last decade. Having such a great group of people who provide a continuously growing list of proposed algorithms, it is rapidly finding solutions to its problems. However, we are still far away from being successful. Therefore, more and more people are entering the field to make the watermarking idea useful and reliable for the digital world. Of these different watermarking algorithms, some smash others in terms of basic watermarking requirements like robustness, invisibility, processing cost, etc.

In this book, we study how to protect ownership of digital images using the robust and blind watermarking technique. we evaluate the performance of the algorithm from the watermarking literature against again a selected set of attacks and distortions and try to figure out the properties of the methods that make them vulnerable or invulnerable to these attacks.
