提出了一种针对UnderMP3Cover的RS(regular-singular)隐写分析新算法。通过分析RS算法产生误差的原因,选取了更适合的分辨函数,修正了不同码率下的MP3初始偏差,并改进了拟合方式,同时,在实验对比中选择了效果更佳的翻转算子。实验结果表明,算法可以有效地估计出秘密信息的嵌入容量,并将平均误差降低到2%,优于现有算法。
A new RS steganalysis algorithm to attack UnderMP3Cover was proposed.By analyzing the error caused by the RS algorithm
the choice of resolution function
the initial bias and the fitting method were modified
the flip operator was also selected in the experiment.Experimental results demonstrate that the proposed method can estimate the length of embedded message effectively and the average error reduces to 2%
which is better than the existing algorithms.
