Health Monitoring system
Health Monitoring system – Smart Health System The wireless medical sensor network is used in healthcare applications that have the collections of biosensors connected to a human body or emergency care unit to monitor the patient’s physiological vital status. The real-time medical data collected using wearable medical sensors are transmitted to a diagnostic center. The data generated from the sensors are aggregated at this center and transmitted further to the doctor’s personal digital assistant for diagnosis. The unauthorized access of one’s health data may lead to misuse and legal complications while unreliable data transmission or storage may lead to life-threatening risks to patients. So, this Letter combines the symmetric algorithm and attribute-based encryption to secure the data transmission and access control system for the medical sensor network. Further, the data is sent to a centralized server through a wireless network. In this case, this server can be a PC connected to the same network, for this transmission UDP protocol can be used. This data can be accessed only through fingerprint authentication.
In the recent period, we observed a gradual rise in expectations of life in various parts of the world, which leads to a frequent increase in the number of aged people. As per the report of the United Nations, the number of aged people will be about 2.0 billion (22% of the total world’s population) by 2050. In research found that nearly 89% of the aged people are living individually. However, a medical research survey found that it is 80% of the aged people elder than 65 and they suffer from at least one disease and older people have every difficulty caring for themselves. By WHO 2015 report 400 million people do not have necessary Health facilities. The number of patients has increased nearly double every four decades, and it is difficult for hospitals to care for all patients. According to the United States report, we can avoid about 41 million deaths yearly if we provide Healthcare facilities at the time. Providing a gracious quality of life to patients is a big social challenge.
Body sensor network provides a large convenience to detect the abnormality in patient’s body and provide proper treatment at the time. Sensors sense the physiological data (Body Temperature, Heart Rate, Blood Pressure, ECG Signal, etc.) periodically every 10 seconds from the patient’s body. In capturing the physiological data from the sensor at the patient’s body, we need to process data pre-processing techniques on sensor data to resolve duplication, errors (Outliers), and missing values in data.
