摘要: Yet Another Steganography Scheme (YASS), a promising steganographic scheme for JPEG images which can resist blind steganlysis via embedding data in randomized locations. However, the randomization is not sufficient enough, as some positions are possible to hold host blocks and definitely not. Meanwhile, artifacts introduced by quantization index modulation (QIM) led weakness its unsafety. In this paper, overcome these drawbacks, we present modified YASS incorporated with further virtual block selection model based permutes secret bits low-density cover probability minimize differences between distribution of image that stego. Consequently, proposed survive attack made specific steganalyzer YASS. Experimental results demonstrate detection achieved steganalyser on our method less than 59%, while about 95% above
