Recently, deep learning-based biometric authentication systems, especially fingerprint authentication, have been used widely in real-world. However, these systems are vulnerable to adversarial attacks which prevent deep learning models from distinguishing input data properly. To solve these problems, various defense methods have been proposed, especially utilizing denoising mechanisms, but they pr...Show More
To minimize security threats using fake fingerprints, various CNN-based fingerprint liveness detection methods have been proposed. However, since existing methods mainly employ a random crop method, key information of target fingerprint may be overlooked during the training process, which may lead to decreased detection accuracy. In this paper, we propose a new fingerprint liveness detection metho...Show More
