目前，基于数字图像的信息隐藏技术现有理论仅集中在算法的研究，问题使得算法设计和性能局限在对应用技术本身的研究和创新，缺乏全面的系统考虑。本文以算法性能和复杂度为目标基础，对影响因素进行收集、分析和归类，提出一套完整的基于数字图像的信息隐藏系统。首先，给出基于两个子系统和9个功能模块的基于数字图像的信息隐藏系统，给出了完整的系统结构；其次，给出信息隐藏系统各个模块的理论基础和功能设置；最后，对预处理子系统中模块之间存在的相互制约和影响关系进行了说明。信息隐藏系统的提出为信息隐藏技术，尤其是算法设计提供了理论基础。

The existing theory of Information Hiding techniques based on digital image only focus on the algorithm research , which makes the design and performance of algorithm be limited to the research of application of the technology itself and the innovation, without a comprehensive system. This paper, col ect, analyze and classify the influencing factors, based on the performance and complexity of the algorithm as the goal, and put forward a set of Information Hiding system based on digital image.Firstly,an Information Hiding system based on two sub-systems and nine functional modules is constructed. Secondly, function setting and theory basis of each module of the Information Hiding system are brought forward. Final y, mutual restriction and effect relation between modules of pre-treatment system are detailed. Information Hiding system is proposed that provides a theoretical foundation for Information Hiding techniques;especial y,for algorithm design.
