FIELD: information technology.
SUBSTANCE: method for incorporation of information into an image compressed by a fractal method based on a formed library of domains, which involves formation stages of a vector of image compression parameters, input of hidden information, extraction of domains and rank areas, correlation of rank areas and domains, formation of a terminal archive; besides, at the image compression stage, bits of hidden information are coded with coordinates of domains.
EFFECT: providing a possibility of hidden transmission of confidential data.
