Fingerprint Spoof Detection: Temporal Analysis of Image Sequence
Tarang Chugh, Anil K. Jain
We utilize the dynamics involved in the imaging of a fingerprint on a touch-based fingerprint reader, such as perspiration, changes in skin color (blanching), and skin distortion,…
Universal Material Translator: Towards Spoof Fingerprint Generalization
Rohit Gajawada, Additya Popli, Tarang Chugh +2
Spoof detectors are classifiers that are trained to distinguish spoof fingerprints from bonafide ones. However, state of the art spoof detectors do not generalize well on unseen sp…
Fingerprint Spoof Generalization
Tarang Chugh, Anil K. Jain
We present a style-transfer based wrapper, called Universal Material Generator (UMG), to improve the generalization performance of any fingerprint spoof detector against spoofs mad…
OCT Fingerprints: Resilience to Presentation Attacks
Tarang Chugh, Anil K. Jain
Optical coherent tomography (OCT) fingerprint technology provides rich depth information, including internal fingerprint (papillary junction) and sweat (eccrine) glands, in additio…
