RETRACTED: A Study on the Spread Spectrum Steganography Based on the High-order Markov Model (Retracted Article)

Spread spectrum communication is a way of information transmission. Steganography based on the principle of spread spectrum has a strong robustness and security. This paper carries out a study on the application of the high-order Markov model of digital grayscale image in its spread spectrum steganalysis. Results suggest that the statistical estimate of the original image and the stego-image obtained by the digital image high-order Markov model is more sensitive than that of the traditional e-secure security index and the image Markov model. Based on the fact that the high-order Markov model of carrier images has a preferable effect on SSIS steganalysis, the accuracy of steganalysis increases and False Positive decreases with the increase of the model order. The SSIS steganalysis scheme of the model is applicable not only to practical calculations but also to users of steganalysis with different requirements on analysis results.
