Securing Blockchain based Electronic Health Record using Multilevel Authentication

Abstract

Electronic health records possess the patient's medication details and their health history. The health records attract the attention of the attackers' as it possesses invaluable information. Loss of electronic health record leads to a wrong medication or surgery. Healthcare systems provide fewer security measures to secure the health records. Blockchain is a distributed and decentralized ledger that plays a vital role in securing the data and transactions. Introduction of blockchain in the healthcare systems protects the health records from the attackers. However, the blockchain faces phishing, dictionary-based, cold wallets, and hot wallets attacks. This paper proposes a multilevel authentication-based scheme to protect the blockchain from the attacks mentioned above.
