信息技术 评估生物识别系统对变形攻击抗性的方法论

[中文适用范围]： 本文件建立了一种评估生物识别系统（BS）对变形攻击（包括多重身份攻击）抵抗力的方法。文件仅限于基于图像的变形攻击。术语“基于图像”包括面部、虹膜和指纹图像数据等模式。 文件建立了： - 生物识别样本修改和操纵的定义，特别关注构成多重身份攻击的操纵。例如，使用面部图像变形进行注册攻击； - 一种测量变形方法变形攻击潜力的方法。 文件还描述了如何将变形算法用于系统评估。 [外文原描述]： This document establishes a methodology to evaluate the resistance of BSs to morphing attacks, including multiple identity attacks. The document is limited to image-based morphing attacks. The term "image-based" includes modalities such as face, iris and finger image data. The document establishes: — a definition of biometric sample modifications and manipulation with a specific focus on manipulations that constitute a multiple identity attack. This can be, for instance, an enrolment attack with face image morphing; — a methodology to measure the morphing attack potential of a morphing method. The document also describes how morphing algorithms can be used for system evaluation.
