Statistical analysis against improved BPCS steganography
ICACC), 2010 2nd International Conference（2010）
摘要
The improved bit-plane complexity segmentation (BPCS) steganography carries on different processings to different bit-planes, with setting high threshold value at the high bit-plane and low threshold value at the low. Not only provides good visual imperceptibility and data embedding capacity, this scheme also is capable of resisting the analysis of the whole complexity histogram. However, it still exists safe loophole. Experimental results show that, the partial statistical analysis the paper mentioned can analysis the existence of secret information; furthermore, it can estimate the embedding threshold value accurately.
