GANprintR: Improved Fakes and Evaluation of the State of the Art in Face Manipulation Detection
João C. Neves, Ruben Tolosana, Ruben Vera-Rodriguez +3
The availability of large-scale facial databases, together with the remarkable progresses of deep learning technologies, in particular Generative Adversarial Networks (GANs), have…
Exploiting Complexity in Pen- and Touch-based Signature Biometrics
Ruben Tolosana, Ruben Vera-Rodriguez, Richard Guest +2
Biometric signature verification has been traditionally performed in pen-based office-like scenarios using devices specifically designed for acquiring handwriting. However, the hig…
Biometric Template Storage with Blockchain: A First Look into Cost and Performance Tradeoffs
Oscar Delgado-Mohatar, Julian Fierrez, Ruben Tolosana +1
We explore practical tradeoffs in blockchain-based biometric template storage. We first discuss opportunities and challenges in the integration of blockchain and biometrics, with e…
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…
Blockchain and Biometrics: A First Look into Opportunities and Challenges
Oscar Delgado-Mohatar, Julian Fierrez, Ruben Tolosana +1
Blockchain technology has become a thriving topic in the last years, making possible to transform old-fashioned operations to more fast, secured, and cheap approaches. In this stud…
Cross-Sensor Periocular Biometrics in a Global Pandemic: Comparative Benchmark and Novel Multialgorithmic Approach
Fernando Alonso-Fernandez, Kiran B. Raja, R. Raghavendra +4
The massive availability of cameras results in a wide variability of imaging conditions, producing large intra-class variations and a significant performance drop if heterogeneous…
SensitiveNets: Learning Agnostic Representations with Application to Face Images
Aythami Morales, Julian Fierrez, Ruben Vera-Rodriguez +1
This work proposes a novel privacy-preserving neural network feature representation to suppress the sensitive information of a learned space while maintaining the utility of the da…
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…
