The article is devoted to the problems of information and analytical activity through the prism of regulatory and legal cooperation between Ukraine and foreign countries. The article defines information and analytical support as one of the main elements of the organization of the system of state authorities. This activity is reduced, firstly, to information and research work aimed at supporting operative and investigative activities, and secondly, to analytical work aimed at supporting strategic decision-making in this area and coordinating the activities of these bodies. Emphasis is placed on the fact that analytical activity has increased attention to the protection of personal data. The personal nature of certain types of information, as well as the use of privacy-intrusive methods to obtain them, place particular importance on surveillance mechanisms and measures to ensure security. The development of information technologies led to a new need for personal data protection. It is noted that analytical work is one of the main elements of the process of cognition, which is carried out in the process of solving the tasks of state authorities. Analytical work makes it possible, by processing certain unfinished information, to obtain knowledge on the basis of which appropriate decisions can be made. At the same time, a necessary condition for the effective performance of analytical measures is the availability of an appropriate information system. It was concluded that the national information and analytical system cannot be recognized as full-fledged, intended for analytical support of the activities of state authorities, without an international legal system of regulation of personal data. The solution to the considered problem can be the practical implementation of an information and analytical system, which includes a set of modern information technologies in the field of analytical data processing, the use of artificial intelligence subsystems, which make it possible to compare and analyze information on the basis of multi-component modules, predict the actions of persons and their locations possible location, give recommendations on the organization of activities of state authorities.
