摘要
文章阐述了隐写系统的定义及安全性,推导出不同位平面随机嵌入机密信息的公式,并开发相关代码,对实验结果进行比较分析。根据理论研究及实验结果提出了图像LSB位平面及第二位平面中嵌入机密信息都不易引起视觉感知的结论。
It was described the definition and security of steganographic system.It was obtained inferential reasoning formula of embedding secrets in different bit-planes.In addition,we developed the source code and do the experimental analysis in this paper.According to the theory study and experimental results,we proposed that the LSB plane and the second bit plane cater for embedding secrets.
