Публікація Method of cluster statistical coding of information resource data(CEUR Workshop Proceedings (CEUR-WS.org), 2020) Barannik, Vlad.; Tupitsya, I.; Hahanova, A. V.; Parkhomenko, M.; Ihnatiev, O.A method of cluster statistical coding of information resource data using internal data restructuring is being developed. The analysis of transformations of the nature of the law of distribution of probabilities of the appearance of elements in a message as a result of clustering by the number of series of units is carried out. The factors that have a significant impact on the effectiveness of the developed method of coding an information resource are analyzed from the standpoint of additional reduction of the structural redundancy of the output code sequence.Публікація Method of Selective Steganographic Data Hiding Based on Graphic Containers(IEEE, 2022) Tverdokhlib, V.; Barannik, D.; Kulitsa, O.; Savchuk, M.; Chornomaz, I.; Parkhomenko, M.An approach to the construction of a selective algorithm for steganographic information hiding based on graphic type containers is proposed. Unlike to most of existing approaches, proposed algorithm takes into account the container fragments content features. So, in the source container, initially performs search for a transformants set suitable for modification. In the next step, within each such identified transformants, a components set that are potentially acceptable for direct modification determines. At the same time, the search parameters for both the transformants set and the components can be modified using the stego key parameters. Encapsulating the secret message bits procedure considered. In this case used an approach based on indirect encapsulation, during which the component decimal value changes. Based on the fact that the algorithm does not make changes to the container that are characteristic of most known steganographic methods, and also due to the fact that the number of encapsulated bits within the container is insignificant, the proposed approach is potentially resistant to stegoanalysis methodsПублікація The concept of a quantitative sign formation for the internal restructuring of information resource data(Springer, 2020) Barannik, Vlad.; Parkhomenko, M.; Gurzhii, P.; Azatov, A.; Shaikhanova, A.; Tupytsya, I.; Karpiinski, M.; Pershin, A.Outlines steps to develop a method of forming a compact representation of the segmented images based on the detection of the two-component vector of tuples for linearized transformant. Dependencies for bit rates are compared in the case of processing the key frames of a saturated image stream using various compression methods. Identified modes that achieved delivery of the video stream in real time.Публікація Video encoding to increase video availability in telecommunication systems(Taras Shevchenko National University of Kyiv, 2020) Barannik, Vlad.; Babenko, Y.; Shulgin, S.; Parkhomenko, M.Article shows presence of the imbalance caused by insufficient level of productivity of modern and perspective information communication technologies concerning information intensity of bit streams. It is described how imbalance level reducing can be formed as a result of increasing of information processing technologies efficiency and that JPEG platform is the basic concept for construction of technologies of compression representation. Therefore it is proposed to provide further development of video processing methods using individual components of the JPEG platform for improving the integrity of information in terms of ensuring the required level of its availability.:
