摘要

由于使用了新的3D面具，检测面部呈现攻击的系统面临着巨大的挑战。被动太赫兹成像提供了特定的物理特性，可以提高演示攻击检测能力。本文的目的是介绍在250 GHz被动成像中使用新型3D人脸面具进行人脸呈现攻击检测的研究成果。对使用定制3d打印和定制柔性3d乳胶面具的面部识别系统的呈现攻击进行了全面分析，并提供了各种物品的光谱特征。描述和讨论了一组不同欺骗项的实验。最后，提出了一种250 GHz被动成像的演示攻击检测方法。

Face presentation attack detection with passive imaging at 250 GHz

Systems for detecting face presentation attacks are facing great challenges since new 3D facial masks are used. Passive terahertz imaging offer specific physical properties that may improve presentation attack detection capabilities. The aim of this paper is to present outcomes of study on using novel 3D facial masks for face presentation attack detection in passive imaging at 250 GHz. A thorough analysis of presentation attacks for facial recognition systems using custom 3D-printed and custom flexible 3D-latex masks is provided together with spectral characterization of various items. A set of experiments with various spoofing items is described and discussed. Finally, a presentation attack detection method with passive imaging at 250 GHz is presented.
