摘要
图像隐写分析是检测、提取和破坏隐写图像中秘密信息的技术,是信息安全领域的研究热点之一。由Westfeld提出的F5隐写算法是一种重要的图像隐写算法。分析了F5隐写算法及其隐写系统,讨论了一种针对F5隐写算法的隐藏检测方法,并给出了具体实现的算法。实验结果表明,F5算法采用矩阵编码,提高了嵌入效率。
Image steganalysis is a technique of detecting, extracting and destroying the hiding information in stegoimage, and it has become one of the focuses in the field of information security. F5 Steganographic Algorithm is a important steganography. F5 Steganographic Algorithm and its Steganographic system are presented. A steganalytic method that detect messages hidden in JPEG images is discussed. Experimental results show that F5 algorithm implements matrix encoding to improve the efficiency of embedding.
