Minutiae-Guided Fingerprint Embeddings via Vision Transformers

no code implementations25 Oct 2022 Steven A. Grosz, Joshua J. Engelsma, Rajeev Ranjan, Naveen Ramakrishnan, Manoj Aggarwal, Gerard G. Medioni, Anil K. Jain

We further demonstrate that by guiding the ViT to focus in on local, minutiae related features, we can boost the recognition performance.

A Unified Model for Fingerprint Authentication and Presentation Attack Detection

no code implementations7 Apr 2021 Additya Popli, Saraansh Tandon, Joshua J. Engelsma, Naoyuki Onoe, Atsushi Okubo, Anoop Namboodiri

Therefore, rather than performing the two tasks separately, we propose a joint model for spoof detection and matching to simultaneously perform both tasks without compromising the accuracy of either task.

C2CL: Contact to Contactless Fingerprint Matching

no code implementations6 Apr 2021 Steven A. Grosz, Joshua J. Engelsma, Eryun Liu, Anil K. Jain

Matching contactless fingerprints or finger photos to contact-based fingerprint impressions has received increased attention in the wake of COVID-19 due to the superior hygiene of the contactless acquisition and the widespread availability of low cost mobile phones capable of capturing photos of fingerprints with sufficient resolution for verification purposes.

White-Box Evaluation of Fingerprint Recognition Systems

no code implementations1 Aug 2020 Steven A. Grosz, Joshua J. Engelsma, Anil K. Jain

While a few studies have conducted white-box evaluations of the fingerprint reader, feature extractor, and matching components, no existing study has provided a full system, white-box analysis of the uncertainty introduced at each stage of a fingerprint recognition system.

HERS: Homomorphically Encrypted Representation Search

1 code implementation27 Mar 2020 Joshua J. Engelsma, Anil K. Jain, Vishnu Naresh Boddeti

Fingerprints: Fixed Length Representation via Deep Networks and Domain Knowledge

no code implementations1 Apr 2019 Joshua J. Engelsma, Kai Cao, Anil K. Jain

We learn a discriminative fixed length feature representation of fingerprints which stands in contrast to commonly used unordered, variable length sets of minutiae points.

Fingerprint Match in Box
