摘要： 提出一种基于多特征的空域替换类图像隐写检测方法。通过分析空域替换隐写原理，找出空域替换类隐写的共性，分别用位平面纹理相似性和位平面统计相关性以及位平面低比特位随机性来度量和刻画该类隐写对图像位平面间关系属性以及图像位平面属性的影响，由此构建针对空域替换类的隐写检测方法。实验结果表明该方法有效，并具有较高的检测准确性和较强的适应性。

Abstract: This paper presents a detection method for image spatial replacement steganography based on multi-feature. By analyzing the principle of spatial replacement embedding, the commonness is found. Texture similarity and statistical relativity of bit plane are used to measure and describe the impact on the relationship of image bit planes caused by such embedding, and the randomicity of the least significant bit plane is used to measure and describe the effect that embedding has upon the bit planes’ attribute, and the detection method for spatial replacement embedding is modeled. Experiment shows that the method is of high detection accuracy and robust adaptability.

Key words: spatial replacement steganography, multi-feature technique, steganography detection, classifier
