Abstract
Convergence of technologies from several domains of computing and healthcare have aided in the creation of devices that can help health professionals in monitoring their patients remotely. An increase in networked healthcare devices has resulted in incidents related to data theft, medical identity theft and insurance fraud. In this paper, we discuss the design and implementation of a secure lightweight wearable health sensing system. The proposed system is based on an emerging security technology called Integrated Circuit Metric (ICMetric) that extracts the inherent features of a device to generate a unique device identification. In this paper, we provide details of how the physical characteristics of a health sensor can be used for the generation of hardware “fingerprints”. The obtained fingerprints are used to deliver security services like authentication, confidentiality, secure admission and symmetric key generation. The generated symmetric key is used to securely communicate the health records and data of the patient. Based on experimental results and the security analysis of the proposed scheme, it is apparent that the proposed system enables high levels of security for health monitoring in resource optimized manner.
Highlights
Healthcare devices are increasingly being networked, raising concerns about their security and safety
In this paper an ICMetric based health sensing scheme is proposed that employs the Mechanical Systems (MEMS) accelerometer and other device characteristics to generate a sensor identification called the device ICMetric
This device ICMetric possesses the quality that it is generated without human intervention and only when it is required
Summary
Healthcare devices are increasingly being networked, raising concerns about their security and safety. Health monitoring devices are available for a variety of purposes like medical, fitness, entertainment and lifestyle monitoring often described as “quantified self” [1]. Devices like pacemakers can be implanted into a patient’s body while smart watches and wearable sensors function externally When these healthcare devices become part of a network like the Internet of Things, we are faced with a situation where the devices are exposed to potential attacks. There are sensors that monitor a person’s vital signs like breathing, heart rate and body temperature at regular intervals Since these sensors monitor a person’s physiological responses, it is imperative to secure the device, data, patient and health professional in a resource efficient but comprehensive manner [2]
