Iris Liveness Detection Competition (LivDet-Iris) – The 2023 Edition

This paper describes the results of the 2023 edition of the “LivDet” series of iris presentation attack detection (PAD) competitions. New elements in this fifth competition include (1) GAN-generated iris images as a category of presentation attack instruments (PAI), and (2) an evaluation of human accuracy at detecting PAI as a reference benchmark. Clarkson University and the University of Notre Dame contributed image datasets for the competition, composed of samples representing seven different PAI categories, as well as baseline PAD algorithms. Fraunhofer IGD, Beijing University of Civil Engineering and Architecture, and Hochschule Darmstadt contributed results for a total of eight PAD algorithms to the competition. Accuracy results are analyzed by different PAI types, and compared to human accuracy. Overall, the Fraunhofer IGD algorithm, using an attention-based pixel-wise binary supervision network, showed the best-weighted accuracy results (average classification error rate of 37.31%), while the Beijing University of Civil Engineering and Architecture’s algorithm won when equal weights for each PAI were given (average classification rate of 22.15%). These results suggest that iris PAD is still a challenging problem.

1. Introduction

LivDet-Iris 2023 is the fifth competition in the LivDet-Iris series offering (a) an independent assessment of the current state of the art in iris PAD [7, 3] algorithms, and (b) an evaluation protocol, including datasets of bona fide and spoofed iris images, including the most recent PAI. This means that, after the competition is closed, researchers can still compare their solutions with LivDet-Iris winners and baselines. LivDet-Iris 2023 has been included in the official IJCB 2023 competition list. ¹
