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…
