BLOCKCHAIN TECHNOLOGY USAGE FOR DECENTRALIZED AND RELIABLE STORAGE OF MEDICAL DATA

Introduction. In an era characterized by the rapid digitization of almost every aspect of our lives, the healthcare industry has witnessed unprecedented progress. This progress, however, has given rise to unique challenges, especially with regard to the safe, secure, and efficient storage and management of large volumes of sensitive healthcare data. This is where the potential of blockchain technology comes into play, offering promising solutions to the healthcare data challenge. It is in this context that this paper explores the use of blockchain technology for decentralized and secure storage of medical data. Based on decentralization, security, and immutability, blockchain technology has the potential to revolutionize the healthcare industry. Its ability to provide secure, verifiable, and permanent methods of recording data is crucial to improving the integrity and accessibility of medical data while maintaining patient privacy. In addition, the decentralized nature of blockchain technology reduces the risk of data loss, theft, or corruption often associated with centralized databases. Purpose. The purpose of the study is to reveal conceptual approaches to the implementation of a blockchain-based information system that provides decentralized and reliable storage of patient medical data. Results. The scientific article reveals algorithms that will facilitate consistent and reliable decentralized storage of medical data on many nodes, ensuring data integrity and availability. Remote interaction between patients, healthcare providers, and medical data stores is ensured in a secure manner while maintaining confidentiality. We list the functionalities of a smart contract that regulate access to and modification of medical data in the blockchain, ensuring compliance with healthcare legislation and patients' privacy rights. Discussion. Implementation of the proposed blockchain system in medical institutions to ensure decentralized and secure storage of patients' medical data, allowing for reliable monitoring of these records while maintaining confidentiality and authenticity.
