Among all Internet of Things (IoT) devices, a subset of them are related to users. Leveraging
these user-related IoT elements, it is possible to ensure the identity of the user for a period of …

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 …

Rapid advances in semiconductor fabrication technology have enabled the proliferation of
miniaturized body-worn sensors capable of long term pervasive biomedical signal …

The shortcomings of conventional access control systems for high‐security environments
have led to the concert of continuous authentication. Contrary to traditional verification, in …

In recent years, physiological signal-based authentication has shown great promises, for its
inherent robustness against forgery. Electrocardiogram (ECG) signal, being the most widely …

Nowadays, the method of simple‐feature extraction has been extensively studied and is
used in PPG biometric recognition; some promising results have been reported. However …

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

Security issues are becoming critical in modern smart systems. Particularly, ensuring that
only legitimate users get access to them is essential. New access control systems must rely …

Background There is worldwide demand for an affordable hemoglobin measurement
solution, which is a particularly urgent need in developing countries. The smartphone, which …

Nowadays, the number of mobile, wearable, and embedded devices integrating sensors for
acquiring cardiac signals is constantly increasing. In particular, plethysmographic (PPG) …
