摘　　要：从信息的特性入手,在深入理解信息隐藏技术机理的基础上,提出了广义信息隐藏技术的概念及其模型,使一些有关古典隐蔽术和现代信息隐藏技术的基本问题得到了合理的解释.根据这个新概念所揭示的原理,得出了"掩盖信息的存在不是信息隐藏的必要条件"的重要结论,拓宽了信息隐藏技术的研究思路.When thinking of information hidding technology, despite the fact that many positive results in the application field have been achieved, some basic problems in its basic theory are still remained. Starting with the feature of the information, a new theory of the generalized information hiding as well as the model buit was suggested when the research on the mechanism of the information hiding was done. And, many traditional steganography and modern information hiding methods was reasonably illustrated. An important conclusion shows that the existance of covered messages is not the necessary condition for information hidding.
