论文摘要
在本文中，我们研究了如何检测具有多种用户的主动身份验证（AA）系统的潜伏期低的入侵者。我们将最快的更改检测（QCD）框架扩展到多用户案例，并制定多用户最快的入侵者检测（MQID）算法。此外，我们将算法扩展到数据效率的情况，在该方案中，在观察样本较少的情况下进行了入侵者检测。我们评估了拟议方法对面部模式上两个公开可用的AA数据集的有效性。
In this paper, we investigate how to detect intruders with low latency for Active Authentication (AA) systems with multiple-users. We extend the Quickest Change Detection (QCD) framework to the multiple-user case and formulate the Multiple-user Quickest Intruder Detection (MQID) algorithm. Furthermore, we extend the algorithm to the data-efficient scenario where intruder detection is carried out with fewer observation samples. We evaluate the effectiveness of the proposed method on two publicly available AA datasets on the face modality.
