摘要

直方图是图像最重要的特征量

经常被攻击者作为分析的凭证

设法使隐写后的直方图失真尽量小是抵御直方图攻击的有效手段。通过对+-1嵌入隐写产生的直方图失真进行分析

提出了利用直方图失真反馈对嵌入进行调整的新思路

并结合该思路对+-1嵌入隐写方法进行了改进。实验结果表明

通过该方法

直方图的实际失真达到了理论的最小值

从而提高了隐写的安全性。本方法同样适用于频域的嵌入方法。

Abstract

The histogram of an image is a key feature statistic

which is often searched by attackers for artifact caused by steganography. Therefore

keeping the abnormality of histogram minimum can be an efficient way to resist steganalysis based on histogram. For purpose of optimizing the stegnographic method

this paper analyzes the abnormality of histogram caused by +-1 embedding

and present a new idea of regulating the process of embedding by the feedback of the abnormality of histogram. Based on this new idea

the +-1 embedding method was improved.Experimental results show that using the method advanced here

the practical abnormality of histogram is theoretically minimum

and the security of steganography is consequently improved. It is also showed that this method is full of promise in Application to frequency domain.
