This document describes a proposed cloud-based health monitoring system using IoT technology. The system uses various sensors to collect patient health data and transmit it securely to the cloud for storage and remote access by doctors. The key components of the system include sensors, a microcontroller, customized software, and cloud server infrastructure. The document discusses the system architecture, data authentication and security mechanisms like encryption that are used to securely transmit sensitive patient health data via the cloud. It proposes using a Real-Or-Random model and Elliptic Curve Cryptography algorithm to authenticate users and encrypt the data transmission between sensors and the cloud server.
