本文基於密碼學，展頻通訊技術，以及雜訊理論，提出數位浮水印影像（ Digital Water Marking Images ）技術的一般方法。 這篇文章主要貢獻在數位浮水印影像 關念與功能架構。首先，主要是在描述數位浮水印影像的相關工作，然而提出一般數位浮水 印影像的模型以及模型參數分析。根據這個模型，來討幾個特殊的數位浮水印影像系統。最 後，結論以及未來研究方向。

　　　　　This paper presents a generic model of digital water marking image techniques Based on the following principles: steganography, spread spectrum communications technology and noise theory. Concepts and functional modules are developed in this paper to describe an abstract scheme of digital water marking image methods. Firstly, we briefly describe the related work in digital water marking images. Then a generic digital water marking model and a general analysis of parameters in this model are presented. According to this generic model, several specific digital water marking image systems will be discussed. Finally, conclusions are drawn and the future directions are discussed.
