Abstract
With the widespread use of mobile devices, iris recognition systems encounter more challenges, such as the vulnerability of Presentation Attack Detection (PAD). Recent works pointed out the contact lens attacks, especially images captured under the uncontrolled environment, as a hard task for iris PAD. In this paper, we propose a novel framework for detecting iris presentation attacks that especially for detecting contact lenses based on the normalized multiple micro stripes. The classification decision is made by the majority vote of those micro-stripes. An in-depth experimental evaluation of this framework reveals a superior performance in three databases compared with state-of-the-art (SoTA) algorithms and baselines. Moreover, our solution minimizes the confusion between textured (attack) and transparent (bona fide) presentations in comparison to SoTA methods. We support the rationalization of our proposed method by studying the significance of different pupil-centered eye areas in iris PAD decisions under different experimental settings. In addition, extensive cross-database and cross-attack (unknown attack) detection evaluation experiments are demonstrated to explore the generalizability of our proposed method, texture-based method, and neural network based methods in three different databases. The results indicate that our Micro Stripes Analyses (MSA) method has, in most experiments, better generalizability compared to other baselines.
