收藏资源简介:
马里兰大学主动认证数据集02 (UMDAA-02) 是由马里兰大学电气与计算机工程系及自动化研究中心创建的一个多模态用户认证研究数据集。该数据集包含141.14 GB的智能手机传感器信号,采集自48名志愿者在Nexus 5手机上,为期两个月。数据集涵盖了多种传感器数据,如前置摄像头、触摸屏、陀螺仪等,用于研究面部识别、触摸屏用户识别和位置服务等。数据集的创建过程是被动收集,反映了志愿者的自然智能手机使用行为。该数据集旨在推动移动平台上的多模态认证研究,解决传统密码认证的不足,提升用户认证的准确性和便捷性。
The Maryland Active Authentication Dataset 02 (UMDAA-02) is a multimodal user authentication research dataset developed by the Department of Electrical and Computer Engineering and the Center for Automation Research of the University of Maryland. This dataset contains 141.14 GB of smartphone sensor signals, collected from 48 volunteers using Nexus 5 smartphones over a two-month period. It covers diverse sensor data including front-facing cameras, touchscreens, gyroscopes and other modalities, targeting research areas such as facial recognition, touchscreen-based user identification and location-based services. The dataset is passively collected during its construction, which authentically reflects the natural smartphone usage behaviors of the participating volunteers. This dataset is intended to advance multimodal authentication research on mobile platforms, address the limitations of traditional password-based authentication, and improve the accuracy and convenience of user authentication.
