摘要: 针对Jessica Fridrich提出的基于无损嵌入容量的LSB信息隐藏检测方法(RS算法),通过实验讨论了对静态图像隐写分析的准确率有影响的几个主要因素,并分析这些因素产生重要影响的根本原因。提出了对RS算法的改进方案,从而减小隐写检测的偏差程度,提高检测的准确度。

Abstract: Based on the LSB detection algorithm of lossless data embedding that is brought forward by Jessica Fridrich, the paper discusses some main effecting factors through experiment, and analyzes the root cause of these factors. An improved RS detection algorithm is proposed, which can minimize the deviation of detection.

Key words: information hiding, steganalysis, RS detection algorithm
