The Watermark Technology Application Research Guided by the Idea of Computer Safe Operation

Electronic information technology in the construction and development of modern society in various fields and trades in occupies the important position and role. Electronic information technology application is based on the computer, but because of various kinds of information in the network virus viral, causing a computer security protection become one of the key technical problems. In recent years, the watermarking technology in the widely used in computer security, and achieved ideal effect and function. This paper systematically discusses the research and development of digital watermarking technology, first of all introduced and classification of information hiding technology, then analyses the model of digital watermarking technology, finally, the digital watermarking technology and its application prospect of the development and research of some possible directions are pointed out.
