IoT Secure Framework for Wearable Sensor Data for E-health System

The risk of infection among people may be reduced dramatically with the reduction in patient movement especially during the pandemic situation like the COVID-19 virus. In such scenarios, a dramatic increase is observed among people in availing tele-healthcare services. The Internet of Things and Cloud Computing technologies are leveraged in this paper while the patients are provided with clinical exams through tele-medical laboratory services by technicians in a hospital. Consultation or validation of the results obtained from the IoT devices is enabled by transferring this data to the hospitals and doctors to the cloud environment. A virtual health team is set up with the hospital clouds by integration of various hospital data, medical doctors, technicians, and nurses on a distributed scenario along with blockchain-based intrinsic security to carry out the workflow of the healthcare system. Ethereum platform is used for assessment of the public, private and hybrid blockchain scenarios.
