Review of Digital Watermark Technique, Theory and Application (Part 1)

The development of digital watermark is reviewed in this paper, the security, robustness and transparency of digital watermark is adequately analyzed. By using the conception of cryptology, watermark can work in the field of content authentication, fingerprint, "multi-bit watermark" and "several watermarks" as well as copyright protection. Theories related to watermark are introduced in detail, including communication model, related detection model, hiding information capacity analysis and security of steganography. Finally, digital watermark is forecasted in terms of technology, theory and application, indicating the developmental trend of watermark application.
