摘要: 提出一种基于统计特性的LSB密写分析方法,这种方法根据密写对原始数据统计特性的影响来判断秘密信息的有无.实验结果给出了不同阈值时的检测性能,当秘密信息量较大时,两类错误概率都可以得到有效控制.

关键词: 密写分析, 最低比特位, 信息隐藏

Abstract: This paper proposes a novel steganalysis technique based on the statistics method for LSB insertion, in which the change of statistical characteristic caused by information hiding is used to judge the presence of secret message. Numerical results show the performance of this developed method with different thresholds and, especially, both kinds of judgment error probability can be effectively controlled with the increase of embedded information.

Key words: information hiding, steganalysis, LSB
