English Abstract
The fast and continuous growth in using internet and the simplicity of copy and store processes of (images, audios, videos clips and texts) without pre-authorization from the owner, led to the appearance of digital image watermarking.
The proposed system is one of the solutions for patent and copyright protection from those unauthorized users.
Furthermore, it prevents unauthorized users from manipulation, illegal use and redistribution of such materials.
There are several available algorithms of digital image watermarking that currently used Discrete Wavelet Transform (DWT) or Contourlet Transform (CT) separately.
In this thesis, we propose a new robust and secure system that is based on the combination between two different transforms DWT and CT.
The new system has been implemented efficiently and successfully.
The experimental results showed that combining two transforms improves the imperceptibility and robustness and provide better results in comparison with other algorithms based only on DWT or CT separately.
The proposed system has been tested against five types of common image attacks.
Performance evaluation of the proposed system shored improved results in terms of imperceptibility, robustness, and high tolerance against these attacks; accordingly, the system is very effective and applicable.
