Abstract
Digital watermarking technology being an important application of information hiding technology has become currently a hot issue in the field of digital information security. This chapter first discusses the digital copyright protection and safety requirements of the digital museum and then describes a common model of information hiding, digital watermarking technology of discrete cosine transform (referred as DCT), and its features in detail. At the same time, the chapter gives a DCT-based JPEG color image invisible watermarking algorithm, as well as swf animation file information hiding watermarking algorithm, in order to improve the information watermark security and attack resistance in the digital museum. The experimental tests show that the algorithm can better balance between imperceptibility, robustness, and security.
