A Scalable Privacy Preservation Block Chain-Based Method for Smart Healthcare System

In this study, we propose a scalable privacypreserving blockchain mechanism for smart healthcare systems. The rapid digitization of medical data has made security, scalability, and privacy vital. This approach minimizes risks associated with sensitive healthcare information by utilizing the decentralized architecture of blockchain to create a secure, transparent, and efficient healthcare information management platform. The system showed an increase in transaction throughput, a reduction of the latency, and an enhancement in energy efficiency compared with traditional approaches through simulations. Moreover, state-of-the-art cryptographic approaches provided strong privacy protection by reducing the risk of data leaks and malicious access. Smart contract implementation further optimized operations by facilitating secure and automated healthcare workflows. This method solves the growing issues in the area of managing healthcare data while delivering a much more scalable, secure, and patient-centric solution for contemporary healthcare systems.
