The relevance of the topic is determined by the rapid digital transformation of society and the substantial increase in personal data processing volumes, which necessitates the enhancement of administrative and legal mechanisms that ensure a balance between effective state control and the protection of citizens' constitutional rights. The subject of this research is the system of administrative and legal norms regulating the notification procedure to Roskomnadzor regarding personal data processing. The study aims to analyze systemic problems of this mechanism and substantiate the need for its technological modernization. The research findings revealed several systemic shortcomings inherent in the current notification framework, primarily concerning excessive bureaucratic burdens, a pronounced lack of automation, and undefined criteria for data updates. As a solution, the study proposes the concept of a «Personal Data Operator's Personal Account» with authentication through the Unified Identification and Authentication System (ESIA), integrated with automated notification systems, notification lifecycle management tools, and an AI-assistant. Particular attention is devoted to developing a proactive regulation model that ensures equilibrium between effective state control and reduced administrative burden on operators. The author concludes that technological modernization of the notification procedure is essential for minimizing administrative barriers, enhancing control efficiency, and strengthening the protection of the right to privacy.
