Bijit Barman, Satyajit Sarmah · 2025
In healthcare, blockchain can enable secure and transparent management of electronic medical records (EMRs), enabling shared connectivity and data security across different representatives or stakeholders while preserving and securing patient confidential data, accuracy, and precision. An evidence-based affirmation can increase trust among patients, vendors, and regulators by reducing hazards related to illegal access & data breaches. Blockchain can overcome centralized systems that do not have access to it. This review intended to study how to preserve and secure healthcare data against external attacks. For these, a blockchain-based distributed system of storing electronic medical records (EMRs) is viewed where transactions will be kept in InterPlanetary File System (IPFS). This will ensure the security of EMRs and ease of sharing among the different stakeholders.
