BTG-AC: Break-the-Glass Access Control Model for Medical Data in Wireless Sensor Networks

Abstract— Wireless sensor networks (WSNs) have recently at-tracted much interest in the research community because of their wide range of applications. An emerging application for WSNs involves their use in healthcare where they are generally termed wireless medical sensor networks. In a hospital, outfitting every patient with tiny, wearable, wireless vital sign sensors would allow doctors, nurses, and other caregivers to continuously monitor the state of their patients. In such a scenario, patients are expected to be treated in reasonable time, so an access control model is needed, which will provide both real-time access to comprehensive med-ical records and detect unauthorized access to sensitive data. In emergency situations, a doctor or nurse needs to access data im-mediately. The loss in data availability can result in further decline in the patient’s condition or can even lead to death. < final year projects >
