An improved BPCS Steganography based on Dynamic Threshold
The bit-plane complexity segmentation (BPCS) steganography has good visual imperceptibility and high data embedding capacity, but the original BPCS method is vulnerable to the statistical analysis of complexity histogram. A modified BPCS method was proposed to enhance the security, but the deficiency still exists. Basing on the analysis of the original and modified BPCS method, an improved BPCS algorithm is proposed. While preserving the superiority of modified BPCS method, the improved method enhances the capability of histogram statistical analysis immunity, and increases the PSNR in some degree.
