摘要
基于位图的隐写分析方法较有效的检测算法是RS法,其检测率达到0 05bpp。通过对RS法的分析,提出一种针对该方法的隐写算法,使隐藏率达到0 2bpp。
At present, RS steganalysis is more effective steganalysis based on bitmap, it indicates that the detecting_rate is less than 0.05 bits per sample. With studying RS steganalysis, a steganographic algorithm which can resist this steganalysis was showed, it's safe bit_rate is less than 0.2 bits per sample.
