Abstract: In this paper, a detecting method is proposed for popular utility called InplainView, according to embedding scheme and the analysis of features. Furthermore, the steg key recovery problem is studied in case of hidden message encrypted by password. Through the analysis of frequencies distribution graph, correct password can be easily attained. At last, the experimental results indicate that the steganalysis method is simple, efficient and practical.

Key words: steganalysis, steg key, information hiding

摘要: 针对互联网上流行的真彩位图文件的隐写算法工具InplainView, 根据算法嵌入原理和特征分析,成功实现了对隐秘图像的检测;通过研究从隐秘图像中所提取消息的字符频度分布,提出了对嵌入消息加密的密钥恢复解决方案,有效提高了隐写分析性能。最后的实验结果表明,该隐写分析方法简单、高效,便于实用。
