Evaluation of PPG Biometrics for Authentication in different states

Autor: Yadav, Umang, Abbas, Sherif N, Hatzinakos, Dimitrios

Amongst all medical biometric traits, Photoplethysmograph (PPG) is the easiest to acquire. PPG records the blood volume change with just combination of Light Emitting Diode and Photodiode from any part of the body. With IoT and smart homes' penetrati
