In the COVID-19 pandemic situation, the transmission of health records sharing and maintaining the integrity of data to receive the end-user is not consistent. Already, some countries decide to conduct lockdown using data models. In this scenario, the end user loss of integrity, loss of confidentiality and security on health records impacts the patients. The security of electronic health records (EHR) is a challenging task especially in COVID-19 like situations. It is a necessity to share secure EHR to physicians and patients which plays a vital role in COVID-19, and also data availability, scalability, and performance of data to receive the end-user is the loss of integrity. In this paper, we proposed an integrated approach of blockchain 4.0 technology used in IoT-based cloud environment that reduce the latency while transmission of health care records and introduce the blockchain-based electronic health records named as BEHR transmission between the physicians and patients. The performance of the proposed approach tested with the NodeJs software and ApacheJmeter open source JMeter Cloud Test environment and proved that the simulation-results of BEHR are an efficient approach in response time and file storage and transmission of EHR than the present conventional system. © 2021 IEEE.
