Additional data is entered into lower category of the domain or units indices, to the rest categories of indices of the domain of the initial image or units from the code book applied is the trial inversion procedure. Now, the domain indices and units from the code book are optimised to be transmitted, along with the data on indices of their orientation, over the communication channel. The receiving party isolates the additional data and restores the initial image.
