KVC-onGoing: Keystroke Verification Challenge
Giuseppe Stragapede, Ruben Vera-Rodriguez, Ruben Tolosana +27
This article presents the Keystroke Verification Challenge - onGoing (KVC-onGoing), on which researchers can easily benchmark their systems in a common platform using large-scale p…
BeCAPTCHA-Type: Biometric Keystroke Data Generation for Improved Bot Detection
Daniel DeAlcala, Aythami Morales, Ruben Tolosana +5
This work proposes a data driven learning model for the synthesis of keystroke biometric data. The proposed method is compared with two statistical approaches based on Universal an…
Mobile Behavioral Biometrics for Passive Authentication
Giuseppe Stragapede, Ruben Vera-Rodriguez, Ruben Tolosana +3
Current mobile user authentication systems based on PIN codes, fingerprint, and face recognition have several shortcomings. Such limitations have been addressed in the literature b…
SetMargin Loss applied to Deep Keystroke Biometrics with Circle Packing Interpretation
Aythami Morales, Julian Fierrez, Alejandro Acien +2
This work presents a new deep learning approach for keystroke biometrics based on a novel Distance Metric Learning method (DML). DML maps input data into a learned representation s…
TypeNet: Deep Learning Keystroke Biometrics
Alejandro Acien, Aythami Morales, John V. Monaco +2
We study the performance of Long Short-Term Memory networks for keystroke biometric authentication at large scale in free-text scenarios. For this we explore the performance of Lon…
Smartphone Sensors for Modeling Human-Computer Interaction: General Outlook and Research Datasets for User Authentication
Alejandro Acien, Aythami Morales, Ruben Vera-Rodriguez +1
In this paper we list the sensors commonly available in modern smartphones and provide a general outlook of the different ways these sensors can be used for modeling the interactio…
Keystroke Biometrics in Response to Fake News Propagation in a Global Pandemic
Aythami Morales, Alejandro Acien, Julian Fierrez +4
This work proposes and analyzes the use of keystroke biometrics for content de-anonymization. Fake news have become a powerful tool to manipulate public opinion, especially during…
BeCAPTCHA: Behavioral Bot Detection using Touchscreen and Mobile Sensors benchmarked on HuMIdb
Alejandro Acien, Aythami Morales, Julian Fierrez +2
In this paper we study the suitability of a new generation of CAPTCHA methods based on smartphone interactions. The heterogeneous flow of data generated during the interaction with…
BeCAPTCHA-Mouse: Synthetic Mouse Trajectories and Improved Bot Detection
Alejandro Acien, Aythami Morales, Julian Fierrez +1
We first study the suitability of behavioral biometrics to distinguish between computers and humans, commonly named as bot detection. We then present BeCAPTCHA-Mouse, a bot detecto…
TypeNet: Scaling up Keystroke Biometrics
Alejandro Acien, John V. Monaco, Aythami Morales +2
We study the suitability of keystroke dynamics to authenticate 100K users typing free-text. For this, we first analyze to what extent our method based on a Siamese Recurrent Neural…
BeCAPTCHA: Detecting Human Behavior in Smartphone Interaction using Multiple Inbuilt Sensors
Alejandro Acien, Aythami Morales, Julian Fierrez +2
We introduce a novel multimodal mobile database called HuMIdb (Human Mobile Interaction database) that comprises 14 mobile sensors acquired from 600 users. The heterogeneous flow o…
Characterization of the Handwriting Skills as a Biomarker for Parkinson Disease
R. Castrillon, A. Acien, J. R. Orozco-Arroyave +6
In this paper we evaluate the suitability of handwriting patterns as potential biomarkers to model Parkinson disease (PD). Although the study of PD is attracting the interest of ma…
MultiLock: Mobile Active Authentication based on Multiple Biometric and Behavioral Patterns
Alejandro Acien, Aythami Morales, Ruben Vera-Rodriguez +1
In this paper we evaluate mobile active authentication based on an ensemble of biometrics and behavior-based profiling signals. We consider seven different data channels and their…
