Implementation of Blockchain Enabled Healthcare System using Hyperledger Fabric

Abstract

The healthcare industry is one of the top priorities for every country, as the government wants to improve the process and provide better services to the public in the health sector. In COVID19, there is a need to immediate response and secured way of storing data due to overwhelming patients admitting to the hospitals. Many stakeholders are involved in the health sector, such as patients, doctors, pharmaceutical companies, laboratories, and hospitals which makes the complete system complex. Security and privacy are the major concern of comprehensive patient-related information accessed by the involved participants. Blockchain technology is capable of ensuring data integrity and privacy with immutable features. The blockchain technology can be implemented in public and private means, but the medical data is sensitive information which cannot be shared to the public. In this paper, the permissioned blockchain is implemented for healthcare sector using Hyperledger Fabric. The Fabric is an open-source platform through which a Smart Contract is developed on the blockchain network. With the help of a smart contract, the secure transaction is performed on the ledger to store the confidential data related to a patient. The data stored in the form of an immutable block ensures the security of health records stored on distributed ledger through a smart contract. With this implementation, the efficient healthcare process is simplified and the transactions with multiple end-users are done securely, leading to transparency and traceability.
