Secure Sharing of Health Data Using Hyperledger Fabric Based on Blockchain Technology

Permissioned block chain network ensures the trust and security with the help of key features of block-chain technology like distributed ledger, smart contract and consensus. Currently the sharing of patient data between health organisation is not safe without trusting each other may leads to data privacy violation. Block chain provides the trust in sharing of patient's medical information between health organizations. In this paper hyperledger fabric frame work based permissioned block chain network is proposed and established among patents and medical institutes to achieve the secured and reliable sharing of the patient's data. Block chain reliably manage the electronic health records eefficiently using Hyper ledger fabric frame work. Implementation results shows that, the hyperledger fabric based Block chain removes the unreliability in sharing of data among health care centres, doctors, public health departments and hospitals. This network also allows the organizations to quickly and safely move medical data in a legally compliant manner as it is a transparent system. The blockchain implemented has achieved the transparent and secure transfer and also controls the access of health data of patients by user policies with smart contracts as chain code. Hyper ledger Fabric provides high levels of performance, protection, and transaction privacy and the results have proved.
