摘要
信息隐藏是一个崭新的研究领域,它横跨数字信号处理、图像处理、语音处理、模式识别、数字通信、多媒体技术、密码学等多个学科。互联网上有很多自由下载的软件可用于信息隐藏。但是对于其相应的检测技术却还是相对薄弱,很少有非常有效的检测算法。该文针对BMP图像信息隐藏新型检测方法的研究,主要针对的是空域的盲检测算法。对BMP新型信息隐藏软件以做出了仔细的研究,得出了针对不同的软件、不同情况下的加入隐藏信息后的特点。研究出了最可疑点统计算法和层次比的算法,并使用C语言进行实现。
Steganography is a novel research area, It is relevant to iots of fields like Digitai Signal Processing, Image Processing, Speech processing, Pattern Pecognition, Data Communication, Multimedia technology, Cryptology and so on. There are some Steganography freeware on internet for people to download. However the Steganalysis techniques are still relatively week, Not many Stegodetection methods are effective,This subject focuses on the novel detection algorithms of BMP stenographic, especially the spatial domain blind detection algorithms. This subject performed detailed research and obtained the typical characteristics of the images after processed by the stego softwares.As for the varied situations, I performed the statistic analysis experiments on the result of algorithms to varied amount of hidden data and various conditions of origin image files to test their performance.
