ABSTRACT

Digital watermarking protects information and is capable of detecting illegal use of proprietary data. This chapter discusses various applications and possible requirements of watermarking in the areas of telemedicine, remote sensing/military, and industry. A digital rights management system recommended watermarking for various applications with variable levels of robustness and other requirements. The crucial requirements of watermarking techniques when applied to satellite images are imperceptibility, lossless embedding, the capacity to extract the watermark blindly, the ability to watermark region of interest and integrity of data. The reversible watermarking schemes are widely used in military applications where copyright protection or ownership authentication is required. A lot of research has been done in the area of digital image watermarking and its application areas in the last twenty years, a major focus being copyright protection and ownership authentication of proprietary images, digital photographs, digital artworks, industrial designs, product models, medical images and remotely sensed images.
