A Review: Security and Privacy for Health Care Application in Wireless Body Area Networks

At present, the utilization of wireless sensor networks (WSN) is extended into various sectors such as military, building monitoring, health monitoring, surveillance, industrial process security, control and monitoring and habitat monitoring. Among these, the implementation of WSN has occurred in health monitoring as body sensor networks (BSNs) which lead to a signification change in the everyday life of people. The major advantage of BSN is consistent physiological monitoring of humans, in which humans have not suffered from any unnecessary noises. Because of the BSNs assisted monitoring, some benefits such as prevention of disease or activity analysis for detection, integration of BSN data with the environment data and rehabilitation after a medical procedure has occurred. Recently several works have been done to maintain and improve the ageing world population from chronic diseases. This review mainly focuses on security and privacy for healthcare applications in wireless body area networks (WBANs). BAN technology establishes a method that monitors the patient’s health status in or around the human body by tiny wireless sensor devices which support medical professionals. However, it faces some difficulties in implementing and designing, like security and privacy for everybody since it holds information. Data should keep data consistency, power failure, high secrecy, validation of sensor versus system compatibility and so on. Furthermore, the review conveys the best way to maintain and improve the dependability of WBAN.
