In article discussed steganographic system based on contraction mapping method. Shown mathematical models of direct and inversed steganographic transform. Considered equation systemn of sensitivity to key variation. Obtained condition to perform maximal sensitivity of system. Analysis of obtained condition in channels with code length limitation is made. It is shown, that in data transfer systems with a lot of quantizing levels, using of the method allows realization of effective data hiding.
