The Internet growth has led to a tremendous amount of multimedia information becoming widely available and to exploring means of new business, scientific, entertainment, and social opportunities. The rapid growth of digital imagery, the increasingly easy access to digital media and the increasingly powerful digital media manipulation tools have made media security a very important issue. This leads to the need for Digital image watermarking (DI\V) for resolving the copyright ownership and verifying the originality of the content. This thesis is concerned with the development and use of digital watermarking and data hiding advanced techniques to secure the image data in general and Remote Sensing (RS) and Cultural Heritage (CH) images in particular.
In this thesis, some advanced approaches of digital watermarking are developed. The proposed work identifies the key problems existing in many of current used watermarking schemes regarding real time watermarking, compatibility to advanced image compression techniques, blind and progressive detection. The thesis addresses several limitations and technical challenges of watermarking and data hiding existing techniques. In particular, the contributions of the thesis can be summarized as follows;
Developing general frameworks for each of the Remotely Sensed Imagery Security (RSIS) and the Cultural Heritage Image Security (CHIS) systems customized to their special requirements.
