It is comprised of more than 600 individuals acquired simultaneously in three scenarios: 1) over the Internet, 2) in an office environment with desktop PC, and 3) in indoor/outdoor environments with mobile portable hardware.
One of the open issues in fingerprint verification is the lack of robustness against image-quality degradation.

Behavioral biometrics can be powerful tools in this fight.
Deep learning has become a breathtaking technology in the last years, overcoming traditional handcrafted approaches and even humans for many different tasks.
ii) We perform a complete analysis of the proposed approach considering both traditional authentication systems such as Dynamic Time Warping (DTW) and novel approaches based on Recurrent Neural Networks (RNNs).
The free access to large-scale public databases, together with the fast progress of deep learning techniques, in particular Generative Adversarial Networks, have led to the generation of very realistic fake content with its corresponding implications towards society in this era of fake news.
We present a platform for student monitoring in remote education consisting of a collection of sensors and software that capture biometric and behavioral data.
The increased need for unattended authentication in multiple scenarios has motivated a wide deployment of biometric systems in the last few years.
