摘要:

随着近年来生物认证系统的使用越来越多,欺骗指纹检测变得越来越重要。在这项工作中,我们实现和评估两种不同的特征提取技术,基于软件的指纹活性检测:卷积网络与随机权重和本地二进制模式。这两种技术都与支持向量机(SVM)分类器结合使用。数据集增强被用来提高分类器的性能和各种预处理操作进行了测试,如频率滤波,对比度均衡,和感兴趣的区域过滤。实验是在2009年,2011年和2013年的活体检测竞赛中使用的数据集上进行的,这些数据集包括近50,000张真实和伪造的指纹图像。我们最好的方法实现了95.2%的正确分类样本的总体率-与之前公布的最佳结果相比,测试误差提高了35%。

英文摘要:

With the growing use of biometric authentication systems in the past years, spoof fingerprint detection has become increasingly important. In this work, we implement and evaluate two different feature extraction techniques for software-based fingerprint liveness detection: Convolutional Networks with random weights and Local Binary Patterns. Both techniques were used in conjunction with a Support Vector Machine (SVM) classifier. Dataset Augmentation was used to increase classifier's performance and a variety of preprocessing operations were tested, such as frequency filtering, contrast equalization, and region of interest filtering. The experiments were made on the datasets used in The Liveness Detection Competition of years 2009, 2011 and 2013, which comprise almost 50,000 real and fake fingerprints' images. Our best method achieves an overall rate of 95.2% of correctly classified samples - an improvement of 35% in test error when compared with the best previously published results.
