A Secured Remote Health Monitoring System Based on IoT

Abstract

The Personal Healthcare Devices (PHDs) measure vital signals of patient. The benefits of PHDs are: (1) wearable (2) Support diseased people (3) Continuous monitoring of health and precaution leads to increased lifetime. Due to the arrival of various communication standards like low power Bluetooth, zigbee, and Internet of Things, the PHDs might be connected to caretakers or doctors and provide proper advice or medication. This project deals with designing a firmware for PHDs, which is interoperable and secure. The benefits of the proposed system are:

1. Low cost PHDs might be designed compatible for the firmware


2. Ensures privacy

• Improves patient care

There exists a challenge in terms of maintaining privacy of patient’s data when connecting PHDs to the network. .In this work, we integrate PHDs with internet for sharing health data using Constrained Application Protocol (CoAP) and AES algorithm for Security purpose. CoAP is predicted on the Representational State Transfer (REST) model and may be considered a real enabler for Internet of Things (IoT). IoT is characterized by an interconnected set of individually addressed and constrained devices during distributed system, with sensing/active devices for physical phenomena, data collection, and applications using sensing, computation and actuation.
