Concerns on widespread use of biometric authentication systems are primarily centered
around template security, revocability, and privacy. The use of cryptographic primitives to …

This paper studies the reliability of geometric features for the identification of users based on
hand biometrics. Our methodology is based on genetic algorithms and mutual information …

Biometric recognition systems based on ultrasonic images have several advantages over
other technologies, including the capability of capturing 3D images and detecting liveness …

Reliable authentication is a key factor in ensuring data security. Information systems
requiring a high level of data security do not use passwords that are considered to be too …

The biometric identification is an important topic with applications in different fields. Among
the different modalities, based-handwriting biometric is a very useful and extended modality …

In data analysis, the hierarchical clustering algorithms are powerful tools allowing to identify
natural clusters, often without any priori information of the data structure, and are quite often …

In this paper we propose a new classifier called a dispersion matcher. Our proposal is
especially well adapted to those scenarios where a large number of classes and a small …

This paper presents an approach to personal verification and identification using hand
geometry. Having extracted, fifteen features of users' right hand, Fingers' width, Area and …

Stream‐based biometric authentication using a novel approach based on spiking neural
networks (SNNs) is addressed. SNNs have proven advantages regarding energy …

The rapid expansion of the Internet is receiving a great deal of attention world-wide. The
technological developments and the increase in online communications have played a vital …
