Ensuring Privacy and Security in Body Area Sensor Networks Manorama

Description: Body Area Sensor Network (BASN), with steady growth and increasing demand on the Internet of Things (IoT) based healthcare network systems, are getting widely popular day by day. A

Wireless Body Area sensor network (BASN) is a wireless network of wearable devices. These

body sensors that are mostly deployed in medical and healthcare systems. The busy way of life

makes visiting clinical advisors or clinics at regular intervals, tedious. Also, several diagnostic

and imaging devices, sensors, and medical equipment have now added up intelligence and

become smart devices or objects, to add up to, one of the important parts of the IoT healthcare

. So, a BASN can be used to connect several different sensors and devices that are placed

both within and external to the human body. With this technology, patients can be monitored

at home, and facilitate relevant data collection which saves time. Each node in a BASN is selfcontained

and capable of searching for and locating a suitable path for data transmission at a

remote site. For data transmission, the BASN node can connect to the internet and allows to keep

track of the patient's health from a far.




The growth of implantable and wearable sensors in BASNs for continuous monitoring of the

condition or function of some body parts entails privacy and security concerns for patients.

Ideally, the sensor gathered data is sent to the sink nodes or to the cloud which may further be

transferred to medical servers. In a BASN, sensor nodes collect data from the human body

and are connected to the external server or other telecommunication networks via a gateway

node. The connecting networks could be a mobile network, a wireless local area network, or a

hospital network. Since these devices use wireless medium to broadcast data, they become

an easier target for attack. In this thesis we aim to register security concerns of BASN

frameworks utilized in the medical care industry. We consider remote monitoring application of

Body Area Sensor Networks which can be adopted for enabling medication at home in

compliance with the treatment suggested by healthcare providers .
