| 摘 要： | 针对目前广泛使用的最低比特位(LSB)信息隐藏算法容易被基于统计检测的隐写分析方法如RS分析或X2分析等检测出来，提出一种新型的LSB隐写算法，能有效地抵抗基于统计检测的隐写分析。对传统LSB缺点和统计检测方法的特点做了分析，改进了传统的LSB隐写算法。采用模拟实验方法证明，改进后的新型LSB隐写分析算法能有效地抵抗统计分析检测。

| Abstract: | Aiming at traditional LSB steganography weakness this paper points that it can be detectable by statistical analysis such as RS and Chi-square analyses. It proposes a novel LSB image steganography algorithm that can effectively resist image steganalysis based on statistical analysis after analysising the feature of LSB steganography and statistical analysis. Experimental results show that the proposed method can effectively resist steganalysis based on these two steganalysis. |
