Physiological Signal Based Security

BANs constantly interact with their physical environment with the help of sensors. Sensors collect process as well as communicate information gathered from their environment. Thus BANs are inherently cyber-physical systems. The BAN interacts with its physical world (human body) by collecting, processing, and communicating health data (vital signals, temperature, pressure) from the person. This information from the environment that is already being collected can be used to provide security to the BAN. Physiological Value based Security (PVS) uses the vital signals of the human body that is collected during health monitoring operation to provide usable security to BAN.
