Method steganography hiding and withdrawal given in spatial area of the scenes with use the direct expansion of the spectrum

Annotations languages:

They are considered steganography of the system of protection to information, in which escapes not only semantic contents information data, but also fact itself to organizations by secret of the issue of the messages. The method steganography hiding and withdrawal given are offered in spatial area of the scenes with use the direct expansion of the spectrum. The Offered method differs from the known account statistical characteristic container-scenes, which allow vastly to raise validity of the withdrawal built-in data i.e. to account of the entering the additional restrictions on importance of the factor to correlations used discrete signal and given spatial area of the scene manages vastly to reduce the amount appearing mistake when removing information given on receiving end.
