In this paper, we propose a system that enables photoplethysmogram (PPG)-based
authentication by using a smartphone camera. PPG signals are obtained by recording a …

This paper presents a photoplethysmography (PPG)-based continuous user authentication
(CA) system, which especially leverages the PPG sensors in wrist-worn wearable devices to …

The wide diffusion of wearable sensors and mobile devices encouraged the study of
biometric recognition techniques that require a low level of cooperation from users. Among …

Remote photoplethysmography (rPPG) allows for noncontact monitoring of blood volume
changes from a camera by detecting minor fluctuations in reflected light. Prior applications of …

This paper considers signals from the cardiovascular system for possible use in biometric
authentication. The signals of particular interest here derive from photoplethysmography …

It is well established that many datasets used for computer vision tasks are not
representative and may be biased towards some demographic groups. The result of this is …

Smartwatches are expected to become the world's best-selling electronic product after
smartphones. Various smart-watches have been released to the private consumer market …

Remote camera measurement of the blood volume pulse via photoplethysmography (rPPG)
is a compelling technology for scalable low-cost and accessible assessment of …

Photoplethysmography (PPG) signals have unique identity properties for human recognition,
and are becoming easier to capture by emerging IoT sensors. Existing research on PPG …

Biometrics have a great deal of potential in healthcare applications, most notably
authentication for medical record privacy and fraud prevention. In this paper, we examine …
