基于置乱与融合的数字图象隐藏技术及其应用

文中首先介绍数字图象的置乱与融合，并基于数字图象的置乱与融合，提出了一种数字图象隐藏方法，在该方法中，地数字图象隐藏的预处理和后处理融合用于将一幅图象隐藏于别一幅图象之中，其次介绍所提出的数字图象隐藏方法，探讨了该方法在数字图象分存与数字水印技术中的应用，实例分析显示，证明该方法可以方便地实现并且具有一定程度的鲁棒笥。

Digital Image Information Hiding Technology and its ApplicationBased on Scrambling and Amalgamation

This paper presents a novel digital image information hiding echeme which based on digital image scrambling and amalgamation. Firstly, this paper introduces how to realize digital image scrambling and amalgamation. Secondly, this paper presents a new kind of digital image information hiding schemes. In the scheme, scrambling technology is used as pre process and post process of digital image information hiding, and amalgamation is used to hide an image into the other one. At last, this paper discusses how to use the scheme into the research area of digital image sharing and digital image watermarking. Examples show that the scheme could be expediently realized and it is robust in a certain extent.
