基于特征码的Imagehide与JPEGX图像隐藏信息检测以及提取

Based on Property Code Steganalysis on Imagehide and JPEGX

信息隐藏技术利用载体中存在的冗余信息来隐藏秘密对象,以隐藏秘密信息的存在。隐写术是信息隐藏的一个重要分支。隐写分析是通过对隐密对象的分析,对秘密信息进行检测及破解的技术。本文针对Imagehide与JPEGX两种网上常见的隐写工具,从分析特征码出发,揭示了检测和提取秘密信息的方法,并进行了实验,取得了较好的结果,证明了该方法的有效性。

The theory of Information Hiding is to embed secret message into cover media in advantage of the redundancy of the cover media so as to hide the existence of the secret message.As one of the important branch of Information Hiding , Steganalysis is the technology to detect and to break the stego-media.This paper explains how to detect and to extract secret information in Imagehideand JPEGX stego-images by property code anasysis.
