An EHR (Electronic Health Record) is a digital patient's medical history representation , comprising details like medications, diagnoses, laboratory test results, allergies, treatment plans, and other relevant healthcare information. EHRs are created to be easily available to authorized healthcare providers and patients, enabling the exchange of information across various healthcare environments and enhancing the quality and effectiveness of healthcare services. Ensuring the high security and accuracy of healthcare data is the top priority of the healthcare industry due to its direct impact on human life. Storing this data on decentralized systems increases its susceptibility to attacks. Blockchain technology can play a crucial role in preserving data due to its decentralized nature and ability to offer an effective solution to data security risks. EHR can be implemented using the Ethereum public blockchain. Here in the proposed work, EHR is implemented using Hyperledger a permissioned blockchain hence providing security to the data.
