Item ІНФОРМАЦІЙНЕ ПРОТИБОРСТВО В ГЕОПОЛІТИЧНОМУ ПРОСТОРІ. INFORMATION STRUGGLE IN GEOPOLITICAL SPACE(2019) Хорошко, Володимир Олексійович; Khoroshko, Volodymyr; Іванченко, Ігор Сергійович; Ivanchenko, IhorGeopolitics has always been associated with the security of the state, since geopolitical processes have arisen with the security of the state, because geopolitical processes have arisen and will arise about the counteraction between geopolitical entities for influencing this or that space. The result of this rivalry is the fact that some subjects gain an advantage and others lose it, which affects their security status. The purpose of the work is the consideration of the problem of information confrontation in the geopolitical space. The conditions and content of geopolitical competition in the information society are established and the threats of information and psychological confrontation in the geopolitical space are formulated. The information and psychological sphere and processes of social relations forming for geopolitical subjects are outlined. The position of geopolitics is investigated and the main qualitative changes that reflect the new conditions and content of geopolitical competition in the information society are identified. Major threats, that arise, are also identified, either as a result of information confrontation with the enemy state, or as a result of information war with it, namely the development by the state aggressor of the national information space, obstruction of the opponent protection of interests in geopolitical space, integration of the opponent. In general, according to the purposes of the confrontation, the objects and subjects of the threats of information confrontation are identified. Any component or segment of the information and psychological space can become the object of information warfare. The subjects of information warfare can be: states, their unions and coalitions; international organizations; non-state, illegal (including illegal international) armed formations and organizations of terrorist, extremist, radical religious orientation; transnational corporations; media conferences and media; virtual social communities; virtual coalitions. Thus, activities in the field of information and psychological confrontation and information influence are defined and considerable opportunities for their use in the present time are given.Item ОБЩАЯ МЕТОДИКА ВЫСОКОЭФФЕКТИВНОЙ ДИАГНОСТИКИ СЛЕДОВ МОНТАЖА В ЦИФРОВЫХ ФОНОГРАММАХ. GENERAL METHODOLOGY OF HIGH-EFFICIENCY DIAGNOSTICS OF TRACKS OF EDITING IN DIGITAL PHONOGRAMS(2019) Рыбальский, Олег Владимирович; Rybalskyi, Oleh; Соловьев, Виктор Иванович; Solovіov, Viktor; Журавель, Вадим Васильевич; Zhuravel, VadymInto the complete set of tools necessary for the judicial technical examination of materials and apparatus of the audio recording, the programs and methodologies (tool) for diagnostic researches of authenticity of phonograms are obligatorily included. Diagnostics of authenticness of phonograms unites researches of originality (i.e. to priority) of phonogram and presence (or absence) in it the tracks of editing. Presently for the record of the phonograms the digital apparatus of the audio recording is mainly used, and editing is produced with the use of digital processing of the signals fixed in phonograms. Therefore there is an insistent necessity of creation of tool for the exposure of tracks of digital treatment (tracks of the digital editing) in phonograms. It is offered by us, along with the instruments worked out before, to apply the neuron networks of the deep learning for creation of the expert tool intended for the exposure of tracks of digital treatment in phonograms. Preliminary researches are completed, and the first version of the program of such high-efficiency system is built. An aim of the study is the creation of general methodology of examining of the authenticity of digital phonograms, based on the tool worked out by authors. In the construction of such system it is suggested to come from that for editing phonogram it is possible from different pre-product – phonograms taped on the different apparatus of the audio recording, and phonograms, taped on one apparatus. For the exposure of tracks arising up at such types of editing, it is necessary to use a different tool, that allows considerably to shorten labour intensiveness and time of examination. For diagnostics of editing, made from the records taped on different apparatus, it is expedient to use the tool built on the basis of fractal approach, in particular, the automated tool is “Fractal”. For diagnostics of editing, made from the records taped on one apparatus of the audio recording, it is expedient to use the tool built on the basis of neuron network of the deep learning. Both types of tool are worked out by authors. Such approach allows to bring down labour intensiveness and time of examining.Item СИНТЕЗ АСИМПТОТИЧНО ОПТИМАЛЬНОГО ДЕТЕКТОРА ШУМОПОДІБНИХ СИГНАЛІВ. SYNTHESIS OF ASYMPTOTICALLY OPTIMIZING NOISE SIGNAL DETECTOR(2019) Євграфов, Дмитро Вікторович; Yevhraphov, Dmytro; Заїчко, Костянтин Вікторович; Zaichko, Kostiantyn; Білогуров, Володимир Андрійович; Bilohurov, Volodymyr; Назарок, Дмитро Станісловович; Nazarok, DmytroThe structure of a special technical tool for detecting noise-like signals, whose intensity varies according to the certain rule, is substantiated. The tool consists of a radio envelope processing device. It is shown, that the main one is a signal processing in the post-detector paths. A joint algorithm for detecting and evaluating a parameter for changing the intensity of a noise signal under a priori uncertainty regarding the radiation power and a parameter for changing the intensity is synthesized. During the synthesis, the uncertainty with respect to the power of the noise signal at the input of the receiver is first overcome, and then with respect to the parameter for changing the noise intensity. The synthesized post-detector algorithm for processing noise-like signals is optimal, when the ratio of the noise signal power to the receiver internal noise power at the output of the linear system tends to infinity. The post-detector detection path consists of a quadratic detector, a centering device, correlation processing channels, a maximum selection device and a threshold device. The maximum amplitude signal at the output of the maximum selection device is compared with the detection threshold. When the threshold is exceeded, an alarm is generated, and an informative parameter for changing the noise intensity is estimated by the number of the correlation channel with the maximum amplitude. The parameters of digital post-detector signal processing are analyzed and a conclusion is made about the possibility of implementing a processing algorithm on microprocessor systems.
