Connecting the dots for health and security monitoring


This talk introduces our research on sensor web for health and security monitoring. In concern of cyber-physical security, we have created sensor web systems that utlize the spatio-temporal electrical signals in power networks, together with cyber signals, for the security and health monitoring of devices, machines and infrastructures. Electrical devices (including computers, appliances, machines) draw energy from power networks and must leave traces of their security and health information in the electrical signals, but this fact was unexplored in the cyber-security literature before our research. In response to the needs of continuous and engagement-free point of care, we invented a series of privacy-preserving seismic sensor web to monitor human and animal health and security. For example, BedDot, attached underneath a bed, senses micro-seismograms from heartbeats and movements and estimates vital signs and activities. FloorDot, placed on a floor, senses seismograms generated by foot steps and other activities to identify the intrusions and activities of daily living (ADL). CageDot, placed under an animal cage, monitors animal activities and vital signs.
