Abstract: Health care system is more affluent and more complex nowadays. One of the main resources in healthcare is health records of patients. Most of the hospital altered to Electronic Health Record (EHR) which enhanced the health care system. EHR consists of most subtle data and this has to be managed properly. There are a lot of issues faced in management of EHR like security, privacy, interoperability. The proposed system describes the solutions for the issues discussed here. This paper proposes a secure EHR system which will preserve the privacy and maintain interoperability using Blockchain. The Blockchain is a data structure that display the way the data are stored and sensibly joined together in a peer-to-peer network. Hyperledger Fabric is used to manage EHR. Sharing health records between the several hospitals is a vital and life-saving during emergency. This will significantly reduce the time needed for the physicians to prescribe and take precautionary actions required as swiftly as possible. This helps to attend the patient’s on-time and save their lives during the emergency circumstances.
