Abstract

The state-of-the-art on known blockchain-based systems for secure management of medical information, conducted in this paper, showed that none of the analyzed solutions satisfies all combined necessary criteria. Therefore, it is necessary to design and implement a blockchain-based system for the secure management of medical information that would satisfy all the necessary criteria at the same time, which is the goal of this study. Since the designed blockchain-based system for secure management of medical information must perform four separate functions, when performing them, information and data will be exchanged, that is, there will be interaction, it was decided to develop the blockchain-based system for secure management of medical information as a multi-agent system. So, the paper developed a blockchain-based multi-agent system for secure management of medical information, which evaluates the medical information’s sufficiency before recording it in the blockchain (the agent for evaluating the medical information’s sufficiency), entering information into the blockchain and obtaining information from the blockchain (the agent for entering information into the blockchain and obtaining information from the blockchain), evaluating the reputation of a health care institution as a blockchain miner (the agent for evaluating the reputation of a health care institution). Thus, the developed system satisfies all specified necessary criteria in a complex. The considered examples of the work of proposed blockchain-based multi-agent system for secure management of medical information showed that the proposed system can significantly increase the security of medical information management, medical information storage and medical information exchange, increase the protection of confidentiality of medical information, thereby increasing the trust of the medical community in medical information technologies and in clinical decision support systems.
