In the healthcare system, electronic medical records are very critical, and they must be authenticated and verified. During the medical check-up, a large amount of patient medical data is generated which includes reports related to blood, lifethreatening diseases, and personal information such as credit card numbers and addresses. Any privacy breach in patient medical records will bring various risks. A simple blockchain (Ethereum) can be effective to validate and authenticate stored data by deploying an immutable ledger. However, the main challenge in the simple blockchain is that its data can be easily accessible. In this paper, the authors create a business network for healthcare using Hyperledger fabric, which ensures that data is only available to the concerned person and its access rights are granted and revoked by the concerned participant. Additionally, the authors tested different scenarios to access blockchain security and its benefits.
