To improve the security of Bit-Plane Complexity Segmentation(BPCS) steganography algorithm,the authors proposed a BPCS steganography algorithm against statistical analysis.Firstly,an image was divided into blocks to calculate the information entropy and the wavelet contrast.Then the blocks were classified by Fuzzy C-Means(FCM) and each bit-plane block was set different complexity thresholds based on the classification result and a random number.Finally,if the similarity of secret data and carrier bit-plane block was less than 0.5,the secret data bit-plane block was negated to replace the carrier bit-plane block.The experimental results show that the proposed algorithm can effectively resist the detection of statistical analysis of the complexity histogram.Furthermore,the visual imperceptibility of stego image has been greatly improved.
