The paper analyzes the possibility of using nonlinear converted stochastic "autoregressive conditional heteroscedastic" process to improve the structural security of transmitted information. The method for estimating the quality parameters of information hiding model is proposed and also the dependence of the correct evaluation probability of information bits on the signal / noise ratio at the receiver at different length values of the encoded sequence elements and at different values of the averaged information volume.
Keywords: autoregressive conditional heteroscedastic, autocorrelation coefficient, security
