Certain investigations on blockchain based secured iot system for healthcare applications

Abstract

newline Quality of life in most countries has been increasing substantially over several decades due to significant improvements in medicine and public healthcare. Consequently, there is a huge demand for the development of cost-effective remote health monitoring, in which the Internet of Things has a great impact on the creation of personalized and patient-oriented medicine. IoT in healthcare services has received growing attention due to the rapid technical advancement of sensor devices, sensor networks, and mobile data transmission. IoT can collect, store, record, and analyze the data, which can be further streamed at a much faster speed. The miniaturization of sensors helps to reduce the material cost as well as power consumption. Healthcare devices connected with IoT focus much on the increase in quality care. Biosensors constitute a multidisciplinary field that has recently emerged as one of the most attractive areas of research. The main advantage of biosensors is that a person can carry them everywhere because the devices are small, light, and wireless. Another advantage of these systems is that they can monitor health conditions in real-time, and also, an IOT device sends and receives data via cloud storage. As a result, the same data can be reachable by multiple devices, which is impossible with current systems.
