We propose a continuous user verification system, which re-uses the widely deployed WiFi infrastructure to capture the unique physiological characteristics.
Thus, the distinct respiratory motion, which is a spontaneous thoracic movement, can be regarded as an ideal biometric for continuous user verification. B.

A respiration-based user authentication scheme is developed to accurately identify users and reject spoofers. Extensive experiments involving 20 subjects ...
We then derive the user-specific respiratory features based on the waveform morphology analysis and fuzzy wavelet transformation of the respiration signals.
This work, in a pioneering approach, attempts to build a biometric system that works purely based on the fluid mechanics governing exhaled breath.
Researchers have leveraged the car- diac biometrics [13], speech characteristics [33], and respiratory patterns [14] to perform continuous user verification.

What are the two types of biometrics used to authenticate authorized users?
Authentication. Biometrics are commonly used to authenticate a person's identity. Some examples of this include fingerprint or facial recognition to access smart phones, or the use of facial recognition technology at airport smart gates.
What is verification and identification in biometrics?
Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. These biological identifiers include fingerprints, hand and earlobe geometries, retina patterns, voice prints and written signatures.
