Abstract	Nowadays, the Internet of Things (IoT) is an emerging technology to interconnect the physical things for providing the best services in hands. IoT has different applications in many areas viz., Smart Health, Smart Transportation, and Smart Cities. Healthcare IoT is an information system to provide quick health services to patients. In medical service applications, IoT facilitates correspondence among specialists and remote patients who are equipped with wearable sensors. Patients' data is critical and any security violation to such data may lead to severe problems. Some existing healthcare frameworks may prompt infringement on the security of the patients. Therefore, security must be implemented carefully in such systems. Blockchain is one of the secure techniques and has been applied to most IoT systems. Scarcely, the significant purposes behind using the Blockchain in medical care frameworks are its conspicuous provisions, i.e., Decentralization, Immutability, Transparency, Security, and Privacy. In this paper, we proposed a blockchain-based healthcare IoT system for the security of Electronic Health Records (EHRs). In this methodology, the health data of the patients are encrypted and stored at the hospital servers and related hash values are stored in the blockchain. Our primary intention is to give an appropriate, secure, and approved admittance to this critical clinical data of the patients using the Ethereum blockchain. This Ethereum based architecture provides an adaptable and secure framework for a smart healthcare system and outperforms the existing methods. © 2022 Bharati Vidyapeeth, New Delhi.
