CYBERSECURITY MODEL BACKED BY BLOCKCHAIN TECHNOLOGY FOR MEDICAL E-CARDS

Abstract

This article examines a security model for medical electronic cards (e-cards) based on blockchain technology and its role in ensuring the confidentiality, integrity, and availability of medical data. The application of blockchain mechanisms in the management of medical e-cards is analyzed, including decentralized data storage, cryptographic protection, and access control. The study demonstrates that blockchain-backed security models significantly reduce the risk of data breaches, unauthorized access, and information manipulation. Research findings indicate that integrating blockchain technology into medical e-card systems improves trust, data transparency, and the overall reliability of digital healthcare services.
