Blockchain technology has attained importance in the field of health as it overcomes the challenges in securing Electronic Health Records (EHR) as well as Electronic Medical Records (EMR) in eHealth systems. Distributed nature of the technology produces a single ecosystem of patient information which can be monitored more efficiently and quickly by doctors, pharmacists and hospitals or anyone who diagnosis or gives treatment. Blockchain technology is used to securely store digital health records and maintain the source record in order to protect and preserve the identity of patients. This work aims to integrate secure data from IoT devices so as to clearly understand the effects of Blockchain in the real environment field. A novel blockchain approach is designed for eHealth and is employed to discover different ways of sharing decentralized view of health information and improve medical accuracy, health and prevent health disorders.
