A Detection Method Research for Data Hiding Based on Markov Chain
For theoretical disadvantages of detecting images signal based on independent and identically distributed (i.i.d.) models used for hiding data, a novel detection method is provided based on Markov chain in the paper. The Markov chain model provides an analytically tractable framework whose predictions are consistent with the performance of practical hiding data algorithms that account for spatial dependencies. Numerical results are provided for image information hiding techniques of using SS, QIM, and LSB, respectively.
