论文摘要
当前冠状病毒大流行状况中的锁定和旅行限制已取代了面对面的教学，并在线教学和会议上会议。最近，视频会议工具变焦因其易于使用的功能和低网络频段的需求而变得极为流行。但是，变焦存在严重的安全性和隐私问题。由于身份验证机制较弱，未经授权的人正在入侵变焦会议并造成干扰（称为变焦轰炸）。在本文中，我们为基于变焦的教学和会议的无缝身份验证机制提出了初步工作。我们的方法基于PRNU（照片响应非均匀性）基于基于摄像机的身份验证，该验证可以验证变焦会议中使用的设备的摄像机，而无需参与者的任何帮助（例如，需要参与者提供生物识别）。小型实验的结果证实了所提出的方法。
The lockdowns and travel restrictions in current coronavirus pandemic situation has replaced face-to-face teaching and meeting with online teaching and meeting. Recently, the video conferencing tool Zoom has become extremely popular for its simple-to-use feature and low network bandwith requirement. However, Zoom has serious security and privacy issues. Due to weak authentication mechanisms, unauthorized persons are invading Zoom sessions and creating disturbances (known as Zoom bombing). In this paper, we propose a preliminary work towards a seamless authentication mechanism for Zoom-based teaching and meeting. Our method is based on PRNU (Photo Response Non Uniformity)-based camera authentication, which can authenticate the camera of a device used in a Zoom meeting without requiring any assistance from the participants (e.g., needing the participant to provide biometric). Results from a small-scale experiment validates the proposed method.
