YASS is a new steganographic method that resists blind steganalysis.A new steganalysis method is proposed for YASS.Based on different block size,the position of different squares with side length 8 is determined,and then co-occurrence matrix for feature extraction and SVM for pattern classification are adopted.Experiments with different block size show that when the block size is less than 16,the detection rate of this method is higher than that f the existing method,and for bigger blocks and the detection rate of this method with the advanced YASS is higher than 90%,much higher than that of the existing other methods.
