摘要越来越多的证据表明，SARS-CoV-2可以在近距离接触之外传播，特别是在通风不足的封闭和拥挤的环境中。为了帮助缓解工作，接触者追踪器需要一种方法来通知那些与感染者同时出现在这种环境中的人。无论是传统的基于人工的手写或电子列表的联系人跟踪，还是支持蓝牙的接近跟踪，都无法有效地处理这个问题。在本文中，我们提出了CrowdNotifier，一个协议，可以有效地通知游客与SARS-CoV-2阳性的与会者的场馆和活动，以补充手动接触跟踪。我们证明了CrowdNotifier提供了强大的隐私和抗滥用能力，并表明它可以扩展到在全国范围内处理通知。
Abstract There is growing evidence that SARS-CoV-2 can be transmitted beyond close proximity contacts, in particular in closed and crowded environments with insufficient ventilation. To help mitigation efforts, contact tracers need a way to notify those who were present in such environments at the same time as infected individuals. Neither traditional human-based contact tracing powered by handwritten or electronic lists, nor Bluetooth-enabled proximity tracing can handle this problem efficiently. In this paper, we propose CrowdNotifier, a protocol that can complement manual contact tracing by efficiently notifying visitors of venues and events with SARS-CoV-2-positive attendees. We prove that CrowdNotifier provides strong privacy and abuse-resistance, and show that it can scale to handle notification at a national scale.
