The analysis of the current development and operation of information systems provided sufficient data for definition of sufficient conditions for a formal presentation steganographic transformation as a set of perturbations of singular values of the matrices (corresponding to the container) those ensure insensitivity (or low sensitivity) of formed steganographic message to compression attacks. The obtained sufficient conditions are independent of the confidential information that embedded to container (spatial or frequency) and specificity of stegano algorithm. The main mathematical tool is a matrix analysis. As the container is considered a digital image. New steganographic algorithm is developed and based on sufficient conditions that received in paper. The algorithm is stable to compression, including low compression rate. The results of computational experiments are presented.
