Програмна система для зберігання та захисту медичних даних на основі блокчейн-технології

Abstract

The paper presents a blockchain-based software system for secure storage and management of medical data. The system ensures transparency, data integrity, and differentiated access through RBAC, encryption, and pseudonymization. It uses a decentralized architecture with technologies such as Node.js, MongoDB, React, and Ethereum or Hyperledger Fabric. The proposed solution enhances patient data protection and simplifies integration with national healthcare systems.
