A Valid Watermark Is Not a Valid Identity: Spatial-Spectral Adversarial Face Evasion with Watermark Preservation
Jefferson David Rodriguez Chivata, Davide Ghiani, Simone Maurizio La Cava +3
Facial image watermarking can support traceability and certification in biometric pipelines, but provenance or manipulation detection alone does not guarantee reliable biometric id…
Deep Data Hiding for ICAO-Compliant Face Images: A Survey
Jefferson David Rodriguez Chivata, Davide Ghiani, Simone Maurizio La Cava +4
ICAO-compliant facial images, initially designed for secure biometric passports, are increasingly becoming central to identity verification in a wide range of application contexts,…
Fragile Watermarking for Image Certification Using Deep Steganographic Embedding
Davide Ghiani, Jefferson David Rodriguez Chivata, Stefano Lilliu +5
Modern identity verification systems increasingly rely on facial images embedded in biometric documents such as electronic passports. To ensure global interoperability and security…
Improving fingerprint presentation attack detection by an approach integrated into the personal verification stage
Marco Micheletto, Giulia Orrù, Luca Ghiani +1
Presentation Attack Detection (PAD) systems are usually designed independently of the fingerprint verification system. While this can be acceptable for use cases where specific use…
Vulnerabilities in Machine Learning-Based Voice Disorder Detection Systems
Gianpaolo Perelli, Andrea Panzino, Roberto Casula +3
The impact of voice disorders is becoming more widely acknowledged as a public health issue. Several machine learning-based classifiers with the potential to identify disorders hav…
