论文摘要
本文描述了IJCB 2022移动行为生物识别竞赛（MobileB2C）的实验框架和结果。 MobileB2C的目的是使用新型的公共数据库，BehavePassDB和标准的实验协议，基于移动用户身份验证系统基于移动生物识别特征（HCI）期间移动设备（HCI）透明化的行为生物验证系统。竞争分为四个任务，与典型的用户活动相对应：击键，文本阅读，画廊刷新和敲击。数据由触摸屏数据和几个背景传感器数据共同获取。考虑了“随机”（具有不同设备的不同用户）和“熟练的”（同一设备上的不同用户试图模仿合法的用户）。参与者获得的结果表明，通过行为生物识别技术进行身份验证的可行性，尽管这被证明是一个非平凡的挑战。 MobileB2C将被建立为持续的竞争。
This paper describes the experimental framework and results of the IJCB 2022 Mobile Behavioral Biometrics Competition (MobileB2C). The aim of MobileB2C is benchmarking mobile user authentication systems based on behavioral biometric traits transparently acquired by mobile devices during ordinary Human-Computer Interaction (HCI), using a novel public database, BehavePassDB, and a standard experimental protocol. The competition is divided into four tasks corresponding to typical user activities: keystroke, text reading, gallery swiping, and tapping. The data are composed of touchscreen data and several background sensor data simultaneously acquired. "Random" (different users with different devices) and "skilled" (different user on the same device attempting to imitate the legitimate one) impostor scenarios are considered. The results achieved by the participants show the feasibility of user authentication through behavioral biometrics, although this proves to be a non-trivial challenge. MobileB2C will be established as an on-going competition.
