In today's conditions of the situation and during the stabilization operation of the combined forces, the Air Forces of Ukraine is one of the main carriers of the combat capabilities of the Armed Forces of Ukraine. An analysis of the tendencies of the introduction of digital technologies of secret management and data transmission in the Armed Forces of the Air Forces of Ukraine during the construction of a modern military control system has been carried out. Today, in addition to the development of new models of aviation technology, the modernization of existing on-board electronic equipment is actively being carried out. The purpose of this article is to develop a steganographic method based on the co-use of direct and indirect data embedding.In this article, the features of using steganographic methods for hiding information are considered. Requirements to the developed method are formed, which consists in minimizing and distributing the distortions of the original container image as a result of embedding information. The main requirements for the design of the indirect embedding method are determined. An estimation of the number of elements that can be embedded in an image block of a certain size is made. A rule for the selection of image regions with different saturation is formulated. A rule for determining the position of the reference and operating points while embedding is formulated. A method of indirect steganographic embedding is developed on the basis of the modification of the working elements of the block relative to the reference point in three levels. It is proposed to use the embedding method based on the modification of the least significant bit. A system of direct and reverse steganographic transformation based on the developed method of indirect embedding is created.
