频域DCT图像信息伪装的隐写分析

Steganalysis of Steganography in Image Based on DCT in Frequency Domain

文章首先概述信息隐藏技术,阐述隐写分析技术的基本原理和分类,重点分析现有的几种隐写分析算法,评价其优缺点,最后指出隐写分析技术的发展方向。

This article first summarized the teclmiques for information hiding, and iUustrated the principle and types of steganalysis. Based on this, the types of the basic steganalysis algorithm were analyzed in details, and the advantages and disadvantages of the present types were discussed. Finally, the developing trend for steganalysis was prospected.
