ARCHITECTURE OF THE SYSTEM OF EXCHANGE OF MEDICAL DATA OF PATIENTS WITH DOCTORS ON THE BASIS OF IOTA

Abstract

The exchange of medical information allows the electronic movement of medical data between different health information systems. Unlike traditional paper documents, electronic ones allow healthcare providers to access and share important medical information. However, existing health systems for the exchange of medical data have faced a number of issues, including confidentiality, security, and lack of patient control. Given all the above, it is proposed to use distributed registry technology, as it can dramatically change the way medical information is stored, providing secure ways to share data. The article discusses the technology of a distributed registry for the Internet of Things (IoT), called IOTA. Blockchain is already used in many healthcare systems as it addresses serious health and privacy issues. However, questions remain about the scalability and performance of the blockchain. IOTA solves these problems by using the DAG (directed acyclic graph) data structure, which allows you to add transactions in parallel. This reduces the time required to confirm transactions, and the number of transactions processed simultaneously can be unlimited. Masked Authenticated Messaging (MAM) allows you to securely transmit encrypted data streams as transactions. Therefore, the proposed system uses IOTA for the secure exchange of medical data. The process of creating and sending medical data to IOTA is illustrated by a specific example. The application of the IAM protocol on the example of transferring medical data from a patient to a doctor is considered.
