LivDet 2021 Fingerprint Liveness Detection Competition -- Into the unknown
This addresses security in biometric systems for applications like mobile authentication, but is incremental as part of a biennial series.
The LivDet 2021 competition assessed fingerprint liveness detection algorithms, focusing on real-world integration and feature efficiency, with 23 submissions setting a record.
The International Fingerprint Liveness Detection Competition is an international biennial competition open to academia and industry with the aim to assess and report advances in Fingerprint Presentation Attack Detection. The proposed "Liveness Detection in Action" and "Fingerprint representation" challenges were aimed to evaluate the impact of a PAD embedded into a verification system, and the effectiveness and compactness of feature sets for mobile applications. Furthermore, we experimented a new spoof fabrication method that has particularly affected the final results. Twenty-three algorithms were submitted to the competition, the maximum number ever achieved by LivDet.
