信息隐藏的检测技术研究

Study of data hiding detection

信息隐藏检测是信息隐藏技术的一个重要方面,文章首先引入了信息隐藏的检测技术的概念,从不同角度出发,将信息隐藏的检测技术划分为对比检测方法、盲检测方法、时空域检测方法、频域检测方法、基于签名的检测方法和基于统计的检测方法。在众多检测技术中,文章着重研究了RQP检测法、Farid检测法和基于计算免疫系统的盲检测方法,并结合水印技术介绍了一种基于小波变换的水印检测算法。最后指出信息隐藏的检测技术有待解决的问题,如检测结果的优化与融合技术。

Data hiding detection is an important part of data hiding technique. This paper introduces firstly the definition of data hiding detection technique. Different points taken into account, the technique is classified as detection by contrasting, blind detection, detecting method in spatial field, detecting method in transformation field, detecting methods based on signature and on statistics. Among different detection techniques, the paper focuses on RQP method, Farid method and blind detection based on computing-immune system. Combining with watermarking, this paper introduces a detecting algorithm based on wavelet transformation. Finally, it points out several problems for further study , such as optimizing and syncretizing technique of the detecting result.
