摘　　要：基于图像的信息隐藏及分析技术是信息安全领域的一个重要方面 信息隐藏技术包括了隐写术和数字水印 信息隐藏检测技术是信息隐藏技术的攻击技术 通过基于图像的信息隐藏检测技术 ,可以判断图像中是否存在信息的隐藏和嵌入 基于图像的信息隐藏检测技术包括了数字图像特征分析、检测算法和实现技术 提出了基于图像的信息隐藏检测技术的知识体系 重点阐述了多种基于图像的信息隐藏检测算法 ,并进行了理论分析和实验测试 分析了现有的几种基于图像的信息隐藏的实现技术 。Information hiding includes steganography and digital watermark The application of steganography can be traced to ancient time, and it is also an important means of secret communication in recent years Information hiding analysis is the art of detecting the message's existence or destroying the steganographic cover in order to blockade the secret communication And information hiding detection is the very first step in information hiding analysis Firstlly, architectonic analysis about information hiding detection is proposed, including the analysis of digital image characteristics, image based detecting algorithms and some problems in its realization Secondly, many detecting algorithms are introduced with theoretical analyses and experimental results in details Thirdly, two applications of detecting technology are put forward Finally, a detecting model used in Internet is discussed
