What are Physiological Biometrics?
Physiological biometrics technology measures the unique pattern of a user’s automatic bodily functions for purposes of identification, authentication, and analysis. Heartbeat, brain activity, perspiration, respiration, eye-reactions to light, emotions, and even body odor can be measured for a wide variety of applications including health monitoring, physical and logical access control, liveness detection, payments, marketing and more.
Where can I find Physiological Biometrics?
Physiological biometrics are at the cutting edge of biometric innovation, but they do exist in real world deployments. The most commonly known and understood of the physiological biometrics is the cardiovascular modality, through which the heartbeat of a user is measured via a vital sign sensor and used for remote health monitoring or continuous authentication for finance and physical access control applications.
We are also on the verge of seeing brainwave biometrics used for authentication, with solutions emerging in this field in the wake of innovative biometric research into the uniqueness of human brain activity.
As more headway is made in physiological biometrics, expect to see them integrated into spaces where continuous and frictionless authentication is required, or where health and fitness data can be useful as part of a larger technological ecosystem. Connected cars, health spaces, and smart home applications are ideal for the novel solutions made possible through physiological biometrics. Researchers have even suggested emotional biometrics be used as a nuclear failsafe to ensure the direst of all decisions can’t be made in a fit of rage.
