新冠肺炎疫情下接触者追踪的隐私风险及保护

Privacy Risk and Preservation in Contact Tracing of COVID-19

许多国家政府都发布了抗击新冠肺炎(covid-19)传播的联系人追踪应用程序,旨在帮助卫生官员发现感染者后追踪接触情况。然而,位置追踪应用程序会对用户隐私造成泄露。因此,为了解决接触者追踪对用户隐私影响,分析、讨论、综述了当前接触者追踪中的隐私风险和保护问题,保证在不降低对公共健康有用性的情况下改善隐私泄露问题。希望通过此研究结果,确保移动联系人追踪应用程序的用户隐私,并鼓励政府努力开发有效的替代解决方案,为用户提供更强的隐私保护。

Many governments released some mobile phone app to fight the spread of novel diseases,such as for the COVID-19 pandemic to assist health officials in tracking down exposures after an infected individual is identified.However,there are important privacy implications of the existence of such tracking apps.In order to solve the influence of current contact tracking on user privacy,this paper analyzes,discusses and summarizes the privacy risks and protection issues in current contact tracking for the first time,aiming at improving privacy issues without reducing the usefulness to public health.We hope in writing this document to ensure that privacy is a central feature of conversations surrounding mobile contact tracing apps and to encourage community efforts to develop alternative effective solutions with stronger privacy protection for the users.
