摘　　要：文中提出了一种新颖的基于多混沌序列加密Word文档,并对数字图像进行Arnold变换的信息隐藏算法。分析了混沌序列Arnold变换图像;设计了信息嵌入与提取算法;并采用动态补偿抵御SPA的检测。利用VB实现Word文档(可以包括字体格式、表格、图形等)的嵌入与提取;给出了信息隐藏的峰值信噪比(PSNR)和SPA分析方法的检测结果。实验表明该算法具有信息隐藏方便、安全可靠、信息隐藏量大等特点。This paper proposes a kind of novel algorithm for information hiding based on chaotic sequences encrypting Word document and digital image of Arnold transform. It analyzes the Chaotic sequence generation and Arnold Transforming digital image; designs algorithm for information embedding and extracting; applies the dynamic compensation method to resist the SPA checking. By using VB the information embedding and extracting of Word document（include font format, form, graph and so on） is realized; the PSNR of the information embedding and the detection result by the SPA analyzing method are calculated. The experimental result shows that the algorithm is convenient, safe and trusted, and large-quantity in information hiding. The project has better application prospect and practical use in internet secret communication.
