Abstract:
Buyers and producers of medical care continue to be worried about the healthcare safety and
confidentiality of electronic healthcare records (EHRs). When a medical system is breached, critical
medical information is exposed. This information is often maintained in centralized systems, which
increases weaknesses and makes cyber-attacks more effective. This review aims to leverage blockchain
technology to improve the safety and confidentiality of electronic health records. This study presents a
novel architecture that avoids centralized storage concerns by using decentralized databases. In
addition, the setup creates a blockchain network based on the Ethereum blockchain to record the hashes
of the gathered information and regulate the connection to it while it has been retrieved. The suggested
framework based on Blockchain is intended to improve the robustness of healthcare management
systems while avoiding security flaws that have been identified in regularly utilized smart healthcare
systems
