摘　　要：提出利用小波分析、水印技术的相关知识将处理后的文本信息加密并嵌入相应的信息载体中进行加密隐藏保护的一种简单方法。小波分析是当前数学中一个迅速发展的新领域,它突破了傅立叶分析在时域和频域方面的局限,是传统傅立叶分析思想方法的发展与延拓。文章首先简述了水印技术基本原理以及Matlab小波工具;对用转换工具turn5将文本及数值转换后的加密及解密的过程作了较为详细的叙述。This paper proposes a simple method which uses the relevant knowledge of wavelet analysis and watermark technology to hide the encrypted text message in the corresponding information.Wavelet analysis which develops rapidly in the current mathematics is the development and extension of Fourier analysis＇ method.It breaks through the limit in time and frequency domain of the Fourier analysis.In this paper,we describe the basic theory of watermark technology,and then give a simple introduction about Matlab toolbox.The procession of encrypting and decrypting of text or number which is converted by turn5 software is more detailed.
