摘要

针对LSB嵌入图像最不重要位的特点

提出了一种基于局部图像稳定性LSB隐写分析算法。该方法借鉴污染数据分析的思想

把秘密信息的嵌入看作是图像数据传递过程中的噪声

利用噪声分析选取合适的图像像素值临界点

达到载密图像的检测目的。理论分析与实验结果表明

该算法在嵌入率较低时具有较高的检测性能。

Abstract

Aimed at the characteristics of LSB steganogtaphy

an algorithm based on local image stability was proposed.Combined with the idea of pollution data analysis

the secret information was regarded as noise in the process of informa-tion transmission.Then using the noise analysis technique

and selecting appropriate critical point value to achieve the detection purpose of the secret information.The theoretic analysis and experimental results show that detection algorithm advances than traditional algorithm in low embedding rate.
