The Earth's aerospace monitoring (ASM) systems use state-of-the-art integrated information technologies that include radio-based detection and surveillance systems using telecommunications. One of the main tasks of ASM systems is to increase the efficiency of decision-making necessary for the timely prevention, detection, localization and elimination of crisis situations and their probable consequences. Modern conditions impose stricter requirements for efficiency, reliability and quality of the provided video data. To ensure compliance with the requirements, it is necessary to provide the appropriate capabilities of the onboard equipment. On the basis of the existing information and communication systems it is necessary to carry out: continuous or periodic assessment of a condition of objects of supervision and control; continuous (operational) collection, reception, transmission, processing, analysis and display of information resources. It is proposed to use UAVs (unmanned aerial vehicles) as a means to perform ASM tasks. The time of organizing communication sessions and delivery of information should vary from a few seconds to 2.5 hours. Untimely processing and delivery of a specific information resource in the management process leads to its obsolescence or loss of relevance, which contributes to erroneous decisions. One way to reduce time is to encode the data. To do this, it is proposed to use video compression algorithms. However, based on the analysis of the possibility of modern methods of video information compression, taking into account the specifics of the onboard equipment of the UAV, the coding problem is not completely solved. The research results show the expediency of using an improved method of video information compression to reduce the computing resources of the software and hardware complex of the onboard UAV equipment and to ensure the requirements for efficiency and reliability of data in modern threats to ASM systems as a whole.

Development of AN Advanced Method of Video Information Resource Compression in Navigation and Traffic Control Systems

In the article, the author analyzes information interventions as threats to the cybernetic security of Ukraine. The relevance of this study is due to the fact that large number of socially dangerous acts aimed at harming state interests can now be used both in the information space and in purely cyberspace. Since such actions are performed using computer systems and performed in cyberspace, we propose to define this type of intervention as “cybernetic intervention”, describing it as a separate group of socially dangerous acts aimed at damaging the information infrastructure of States, vital areas of society's existence. The main aim of this study is to analyze information intervention as a threat to cyber security of Ukraine. The interpretation of terms that make up the conceptual and categorical apparatus of the subject of research is carried out. A narrow definition of the concept of “information intervention” is proposed as the violent intervention of one or more subjects of information relations in the activities of another or others, and a broad definition – a certain set of aggressive actions that are aimed at influencing public opinion and decision-making within one or another country and achieving clearly defined results.

The article deals with the issues of authentication and authorization of users of systems operating on the Internet, considers the problem of reliable access and options to improve and enhance the security and safety of user data. The paper proposes a solution to the problem of improving reliability through an authentication system developed on the basis of sound signal analysis. It has been shown that the problem of protecting user accounts is becoming increasingly important with the spread of Internet technology in the lives of ordinary people.
