摘要

在隐写分析领域

国内外已有很多学者对JPEG图像的DCT系数统计分布模型进行过研究.本文根据数据的统计特征

系统地描述了JPEG净图DCT系数的SαS模型.SαS模型具有很强的柔韧性

随着特征指数α改变

其分布形状就会改变.根据SαS模型的柔韧性

本文提出了一种新颖的、基于净图定量描述的隐写分析方法

这种隐写分析方法与传统模型的隐写分析方法相比

具有更好的隐藏信息检测性能.

Abstract

In the domain of steganalysis

the theory of DCT coefficients statistical distribution model has been addressed in many previous papers.Based on the statistical characters of image's data

this paper introduces the symmetric alpha-stable model of the cover image's DCT coefficient systematically.Because of the adequate flexibility of SαS

its shape of distribution will be changed as the characteristic index α changes.According to SαS model flexibility

a new novel steganalysis method based on cover image quantitative describing is proposed in this paper.Compared with the traditional model's steganalysis method

the performance of the new model's is much better.
