| Summary: | In view of the fact that most images are compressed when transmitted through telecommunica-tion systems and telecommunication systems in the energetics, from the point of view of the practical use of steganographic algorithms in real information security systems, such as their property, the ability to effectively resist a compression attack, is of great interest. This work aims at increasing the robustness of steganographic system against compression attacks to ensure the reliability of the steganographic message perception by developing a steganographic method that implements the embedding of additional information in the spatial domain of the container, us-ing the code control of the frequency components that are under perturbations resulting from the steganographic transformation. The goal was achieved using the code control of information embedding: due to preliminary additional coding of the embedded information with codewords for which the Walsh-Hadamard transformants have the specified properties, which leads to a given localization of disturbances in the Walsh-Hadamard domain of the container as a result of the information embedding. The most significant result is the steganographic method developed based on the formed theoretical basis, for which classes of codewords that provide the highest robustness against the compression attacks were constructed. The significance of the results ob-tained is that the developed method ensured a high reliability level of perception the ste-ganographic messages, significant robustness against the compression attacks, as well as sim-plicity of algorithmic implementation and high performance. |
