Advancing Healthcare Security: A Cutting-Edge Zero-Trust Blockchain Solution for Protecting Electronic Health Records

The effective management of electronic health records (EHRs) is vital in healthcare. However, traditional systems often need help handling data inconsistently, providing limited access, and coordinating poorly across facilities. This study aims to tackle these issues using blockchain technology to improve EHR systems' data security, privacy, and interoperability. By thoroughly analyzing blockchain's applications in healthcare, we propose an innovative solution that leverages blockchain's decentralized and immutable nature, combined with advanced encryption techniques such as the Advanced Encryption Standard and Zero Knowledge Proof Protocol, to fortify EHR systems. Our research demonstrates that blockchain can effectively overcome significant EHR challenges, including fragmented data and interoperability problems, by facilitating secure and transparent data exchange, leading to enhanced coordination, care quality, and cost-efficiency across healthcare facilities. This study offers practical guidelines for implementing blockchain technology in healthcare, emphasizing a balanced approach to interoperability, privacy, and security. It represents a significant advancement over traditional EHR systems, boosting security and affording patients greater control over their health records. Doi: 10.28991/HIJ-2023-04-03-012 Full Text: PD

Securing EHRs With a Novel Token-Based and PPoS Blockchain Methodology

Blockchain technology is vital in strengthening the security of private information, particularly in the healthcare sector. Its features, such as confidentiality, decentralization, security and privacy, address challenges traditional healthcare systems face, such as phishing, denial of service and identity theft attacks. In this regard, our research paper presents a security solution specifically tailored for healthcare applications. This solution integrates decentralized identity management (DIDs) for identity verification, employs the advanced ChaCha20-Poly1305 encryption algorithm to ensure data confidentiality, and utilizes a token-based mechanism for immutable record keeping. Furthermore, it incorporates a pure proof of stake (PPoS) consensus mechanism to enhance system security while optimizing efficiency. This comprehensive and scalable system showcases improvements in cost effectiveness, time efficiency of an average of 6,5 seconds and overall data protection compared to traditional approaches used in healthcare data security
