A Blind Digital Steganography Scheme Based on Complete Complementary Codes

Digital watermarking schemes based on complete complementary codes have been proposed. It has been pointed out that the watermarking schemes can be extended to the steganography scheme because complete complementary code has good correlation properties. In this paper, we propose a blind steganography algorithm which does not need to refer any cover data in the extraction process. In addition, we theoretically evaluate the maximum size of the embedded data and numerically analyze the limit to embed the secret messages under the condition where the peak signal to noise ratio(PSNR) is over 35[dB]. Bit error rate and bit error distribution of the proposed method are also included in this paper.
