Two-channel real-time steganographic system

In the work considered digital steganographic system, based on contraction mapping. The idea of steganogrphic algorithm is grow out of measurement systems in which signal considered as a function of payload and mistake in each moment of measure. The mistake removing algorithm can be considered as decoding system while the stego has a correct mathematical model. The two channel algorithm allows improved precision of payload decoding with almost any proportion of payload signal to carrier signal..
