SYSTEM AND METHODS FOR AUTHENTICATING VITAL SIGN MEASUREMENTS FOR BIOMETRICS DETECTION USING PHOTOPLETHYSMOGRAPHY VIA REMOTE SENSORS

摘要

A method of authenticating vital sign measurements for biometrics detection via a mobile device comprises the steps of: (a) obtaining video of a first body region and a second body region of said user via said at least one front camera sensor and at least one back camera sensor, respectively; (b) extracting pulsatile signals of said user using photoplethysmography imaging (PPGi) analysis of said video obtained from said first and second body regions; and (c) calculating a first heart rate value (FHRV) and a second heart rate value (SHRV). The videos are obtained simultaneously and a comparative output value between first heart rate value (FHRV) and a second heart rate value (SHRV) is calculated.
