Laptiev O. Methodological bases of automated search for digital means of illegal obtaining information retrival

As a result of the dissertation, an important scientific and applied problem has been solved, the essence of which is to develop methodological bases for automated search of digital means of illegal obtaning of information under the conditions of influence of external and internal destabilizing factors. At first, the concept of integrated detection, recognition and localization of digital non-tacit information retrieval based on legal radio signals has been developed, which combines theoretical methods, techniques, models and technological approaches: using fast calculation algorithms; recognition of signals of the means of illegal obtaing information acquisition on the basis of the method of spectral analysis with the use of splines and differential transformations; determination of parameters of signals of the means of illegal obtaing of information on the basis of correlation-regression analysis; localization of the means of illegal obtaing based on the far-field method. The implementation of the concept in the automated software-hardware complex allows to detect, recognize and localize digital means of s illegal obtaing acquisition against the background of radiation of legal devices and systems in the conditions of noise and interference. At first, a method of recognizing the signal of digital means of illegal obtaing of information against the background of legal airwaves is proposed, based on the use of multi-agent clustering with direct communication between agents. At first, a technique for determining the accuracy of localization of digital means of illegal obtaing is proposed, based on a far-reaching method of calculating the coordinates of an emitter with a location determination using the least squares method.
