Integrating Healthcare Management System Using Blockchain Technology

In the realm of modern healthcare, data management grapples with challenges such as transparency, traceability, and privacy, exacerbated by centralized systems’ vulnerability during natural disasters. Blockchain technology emerges as a disruptive solution with transformative potential for healthcare data management. This paper meticulously investigates challenges hindering seamless blockchain integration in healthcare, encompassing regulatory, technical, and ethical dimensions. It emphasizes the critical need for innovative solutions to fortify data security and combat issues like deception in clinical trials within the healthcare domain. Addressing these challenges, the paper proposes a patient-centric blockchain-based framework. This framework employs advanced cryptographic techniques, including ciphertext-policy attribute-based encryption, to establish authorization rights for relevant parties. Proxy re-encryption ensures secure data transfer and requested anonymity, allowing successful decryption without compromising confidentiality. To validate the proposed framework, the paper employs the Burrows–Abadi–Needham (BAN) logic for security evaluation. Simulation using OMNET++ software provides insights into associated storage and computation costs, facilitating a comprehensive assessment of operational efficiency. In conclusion, this paper navigates the challenges of integrating blockchain into healthcare data management, presenting its transformative potential and proposing a robust patient-centric solution. It not only addresses domain-specific problems but also contributes significantly to the broader discourse on technology’s convergence with healthcare. Envisioning a future where blockchain enhances scientific advancement, technological integration, and patient empowerment, the paper underscores the profound influence of blockchain on the healthcare sector.
