Security and Conduction Properties of Interference-Robust Human Body Communication (IR-HBC) for Secure RemoteHealth Monitoring using Physiological Sensor Data
Abstract
With the prolific growth of miniaturized sensors, wearable/implanted physiological sensors are becoming increasinglycommon in medical, healthcare systems and for remote health monitoring sensors. The common method connecting these sensors is Wireless Body Area Network (WBAN). However, WBAN suffers from (1) inter-sensor interference, (2) low security (limited encryption signals from energy-limited sensors) and (3) poor energy-efficiency (RF up-conversion and down-convention, energy- spread in air). Human Body Communication (HBC), which uses human body as a conducting medium, provides an alternate communication technique that performs significantly better than WBAN in these respects. While low- frequency HBC has been around for two decades, interest in using HBC for BAN has drastically increased only recently. However, the science of various mechanics by which signals couple onto and propagate through human body for a wide frequency range is not yet well understood. The overall goal of the proposed work is to develop an in-depth understanding of the fundamental science of signal condition through human body and analyze/reduce security-vulnerability of on-body information. The success of these studies will pave the path towards fully energy-harvested physiological sensors.
