Abstract

This article offers an architectural version leveraging blockchain era to decorate the secure control of Personal Health Information (PHI) throughout healthcare carriers within a decentralized network. By imposing advanced cryptographic protocols, including elliptic curve cryptography (ECC), the version ensures high facts integrity, confidentiality, and green key management, which appreciably optimizes transaction speed and useful resource usage as compared to traditional security techniques like RSA. This approach lets in PHI information from multiple healthcare entities to be securely stored, regarded, and controlled inside a unified blockchain community, mitigating unauthorized get admission to and safeguarding affected person information. Our model supports interoperability with existing health data structures, along with Electronic Health Records (EHR), Electronic Medical Records (EMR), and Personal Health Records (PHR). A dedicated service module is included to standardize and equalize communications among diverse healthcare systems, ensuring consistent information trade and accessibility. The structure additionally introduces robust access manipulate mechanisms, identification verification, and digital signatures to in addition shield towards cyber threats, allowing a resilient system suitable for big-scale healthcare programs. Preliminary opinions screen the model’s capability to deal with giant volumes of PHI at the same time as preserving machine integrity and operational performance, providing a promising alternative to centralized records management tactics. Future research will consciousness on scaling the version for excessive-volume environments and developing extra defences in opposition to evolving threats in peer-to-peer (P2P) networks. This innovative model lays the groundwork for a decentralized, secure, and interoperable healthcare facts gadget with full-size implications for both clinical exercise and biomedical research.
