A real time efficient & secure patient monitoring based on Wireless Body Area Networks

Wearable health-monitoring system is a leading technology, especially in enabling the non-invasive diagnosis of vital functions of the human body. The combined information obtained from such systems can either be relayed directly to any health-monitoring organization in the case of crises or can be logged and analyzed as a part of preventive health measures. With the increasing population density it is difficult to have a real time tracking of health condition of people in an area. Traditional offline method such as using medical survey and making medical records manually are inefficient. In this project hardware for continuous health monitoring and alert system is developed. Different sensors are used to measure various parameters from human body. Reading taken from ECG is huge and is hard to handle, so a compression algorithm is used to compress the readings taken from patient's body. To ensure the security and privacy of patient's health status it is critical to secure the data collected from the person's body, for this we are using Knapsack cryptography algorithm. The encrypted data is then uploaded to the website. With this system the doctor can have access to patient's data from anywhere. The main aim of this project is to setup a virtual hospital with limited resource.
