人与人之间的物理距离是防止COVID-19等疾病传播的关键。一方面,获得有关物理相互作用的信息对决策者至关重要;另一方面,这些信息是敏感的,可用于跟踪个人。在这项工作中,我们设计了波洛,一个系统,收集有关物理交互的隐私保护方式的汇总统计数据。我们展示了我们的系统的初步评估,证明了我们的方法的可扩展性,即使在保持强大的隐私保证。
Physical distancing between individuals is key to preventing the spread of a disease such as COVID-19. On the one hand, having access to information about physical interactions is critical for decision makers; on the other, this information is sensitive and can be used to track individuals. In this work, we design Poirot, a system to collect aggregate statistics about physical interactions in a privacy-preserving manner. We show a preliminary evaluation of our system that demonstrates the scalability of our approach even while maintaining strong privacy guarantees.
