Steganographic vstraivanie given in still image by method of the direct expansion of the spectrum

Annotations languages:

Are considered steganographic methods embed given in containers-images on base of the use complex discrete signal. It is shown that using to technologies of the direct expansion of the spectrum in steganographic system allows to realize steganographic protection to information and provide high reception capacity organized steganochannell. It is offered the most further development of the methods to embed information in still containers-images on base of the use the greater ensembles weakly correlated (the quasi-orthogona) discrete signal.
Keywords: steganographic, difficult discrete signals, direct expansion of spectrum
