LieRHRV system for remote lie detection using heart rate variability parameters

Scientific Reports
The standard polygraph, or lie detector, is limited by its reliance on average heart rate, subjective examiner interpretation, and the need for direct subject contact.

Remote physiological monitoring of neck blood vessels with a high-speed camera

Advanced Optical Technologies
IntroductionSeveral population-based clinical studies suggest that increased Pulse Wave Velocity (PWV) is highly associated with increased cardiovascular disease (CVD) mortality, which is one of the leading causes of death worldwide.

Biometric Authentication Based on Enhanced Remote Photoplethysmography Signal Morphology [PDF]

Remote photoplethysmography (rPPG) is a non-contact method for measuring cardiac signals from facial videos, offering a convenient alternative to contact photoplethysmography (cPPG) obtained from contact sensors.

Attacks on heartbeat-based security using remote photoplethysmography [PDF]

, 2018
The time interval between consecutive heartbeats (interpulse interval, IPI) has previously been suggested for securing mobile-health solutions. This time interval is known to contain a degree of randomness, permitting the generation of a time- and person-

Remote photoplethysmography for heart rate and blood oxygenation measurement:a review [PDF]

Usually measured through obtrusive contact-based methods, heart rate (HR) and peripheral oxygen saturation (SpO2) are critical physiological signs used by clinicians during emergency interventions.

Data-Driven Calibration Estimation for Robust Remote Pulse-Oximetry

Applied Sciences, 2019
Pulse-oximetry has become a core monitoring modality in most fields of medicine. Typical dual-wavelength pulse-oximeters estimate blood oxygen saturation (SpO2) levels from a relationship between the amplitudes of red and infrared photoplethysmographic ...
