Topicality.. In today's digital age, data security is becoming a primary concern in various sectors, especially in healthcare.the critical nature of patient data requires robust protection mechanisms against unauthorized access and potential malicious use. This article examines the changing data security landscape in the healthcare sector and highlights vulnerabilities associated with traditional data storage systems. The paper proposes a model of a system for collecting, storing and exchanging electronic health records (EHR). The paper examines blockchain technology as a revolutionary approach to solving security problems for the exchange of confidential medical data. The goal of this work is to increase the confidentiality of medical data, its integrity and availability, as well as to ensure reliable exchange of this data between medical institutions and other participants by designing and developing software components for creating secure systems for transmitting medical information based on blockchain technology.. The object of research includes systems for the transmission of medical information, which ensure the exchange of data between medical institutions, specialists and specialists, ensuring the confidentiality, integrity and availability of this data.. The subject of research is methods and tools for designing and developing software components necessary for creating and maintaining secure medical information transmission systems. These components include software for encryption, authentication, authorization, and mechanisms for fault tolerance and data recovery. Results. In this paper, we propose a model of a decentralized system for collecting, storing, and exchanging EHR. Conclusions. The results of this study highlight the transformative potential of blockchain technology in rethinking data security paradigms in the healthcare sector. by creating a secure, transparent and efficient platform for managing EHR, the proposed model not only increases the confidentiality and integrity of medical data, but also makes a significant contribution to improving the quality of care and patient outcomes. As we move forward, the introduction of decentralized systems based on blockchain technology in healthcare represents a promising path to address complex challenges related to data security and Privacy, thereby paving the way for a more sustainable and patient-centered healthcare ecosystem.Downloads
