摘　　要：信息隐藏技术不同于传统的密码学,其不仅隐藏信息的内容,而且隐藏了信息的存在性,是全媒体时代信息安全领域的一项重要技术。数字图像置乱,既可作为信息加密的一种方法,又可作为进一步隐藏的预处理,是信息隐藏中重要的方法。本文在分析数字图像置乱技术的基础上,运用其中两种重要的数字图像置乱变换方法作为实例进行了实验,从实验结果可知,置乱效果良好。Information hiding, which is different from traditional cryptography technology, it does not only hide the content, but also hides the existence of the information. It is an important technology in information security area in the current electrical media age. As an important technology in information hiding, scrambling transformation can be regarded as a means of information encode and also it can be used as a pre-processor for further hiding, so it's given more attention. The paper is based on studying methods of scrambling transformation. Two scrambling transformation are put research and put into practice in the paper, and has been got a satisfactory result.
