Enhanced data security and privacy in healthcare using a new secentralized blockchain architecture
Yogendra Kumar · 2025
This paper presents a novel decentralized blockchain architecture to solve the pressing demand for improved data security and privacy in the healthcare industry. The suggested design takes advantage of blockchain’s built-in benefits of immutability, transparency, and auditability while using a clustering technique to reduce computation costs and communication overhead. Strong access control and data integrity are also guaranteed by this resource-efficient method. Our results show that the suggested approach provides robust defense against prevalent security risks in the healthcare sector. Our design yields a 10x decrease in network traffic and a 63% improvement in ledger update time when compared to lightweight blockchain systems and current blockchain, demonstrating its better performance and usefulness for healthcare applications. In spite of these noteworthy developments, further investigation is required to include this architecture with the existing healthcare IT infrastructure, determine whether it is appropriate for certain healthcare situations, and carry out comprehensive testing to determine its practical efficacy. The scalable, transparent, and secure solution that this novel blockchain architecture offers will ultimately enable healthcare organizations to safeguard patient information, uphold confidence, and create a more resilient healthcare ecosystem.
