一种改进的基于马尔科夫链的扩频图像隐写分析方法
An improved image steganalysis method based on Markov chains for spread-spectrum data hiding
摘要
Abstract
We propose an algorithm for steganalysis of images based on spread-spectrum data hiding. We employ Markov chains and a combination of threshold method and improved pattern recognition method, and we can discriminate whether an image contains hiding data through detecting the relativity of correlated pixels of the image. Results of the experiments on Corel' s image library show that this algorithm reduces the false alarm rate and increases the precision rate.关键词
