Mouse Behavior Analysis Based on Artificial Intelligence as a Second-Phase Authentication System
(MDPI AG, 2019-08-01)
[Abstract] Nowadays, a wide variety of computer systems use authentication protocols based on several factors in order to enhance security. In this work, the viability of a second-phase authentication scheme based on users’ ...
AI-based user authentication reinforcement by continuous extraction of behavioral interaction features
(Springer, 2022-07)
[Abstract]: In this work, we conduct an experiment to analyze the feasibility of a continuous authentication method based on the monitorization of the users' activity to verify their identities through specific user profiles ...
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
(EDP Sciences, 2021)
[Abstract] Aims. We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue through comparisons to the full data release, ...
Gaia Early Data Release 3: Summary of the Contents and Survey Properties
(EDP Sciences, 2021)
[Abstract] Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of ...
Gaia Early Data Release 3: Acceleration of the Solar System from Gaia Astrometry
(EDP Sciences, 2021)
[Abstract] Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric ...
Gaia Early Data Release 3: Structure and Properties of the Magellanic Clouds
(EDP Sciences, 2021)
[Abstract] Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements ...
Distributed Fast Self-Organized Maps for Massive Spectrophotometric Data Analysis
(MDPI AG, 2018-05-03)
[Abstract] Analyzing huge amounts of data becomes essential in the era of Big Data, where databases are populated with hundreds of Gigabytes that must be processed to extract knowledge. Hence, classical algorithms must be ...
Gaia Early Data Release 3: The Galactic Anticentre
(EDP Sciences, 2021)
[Abstract] Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a ...
A First Approach to Authentication Based on Artificial Intelligence for Touch-Screen Devices
(MDPI AG, 2020-08-18)
[Abstract]
Most authentication schemes follow a classical approach, where the users are authenticated only once at the beginning of their sessions. Therefore, it is not possible to verify the legitimate use of such a ...
Gaia Early Data Release 3: The celestial reference frame (Gaia-CRF3)
(EDP Sciences, 2022-11-23)
[Abstract]: Context. Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains ...
