In the absence of a vaccine, a small number of countries have managed to control the diffusion of viruses by early detection and early quarantine. South Korea, one of the countries which have kept the epidemics well-controlled, has opened the infected patients’ trajectory to the public. Such a reaction has been regarded as an effective method, however, serious privacy breach cases have been issued in South Korea. Furthermore, some suspected contacts have refused to take infection tests because they are afraid of being exposed. To solve this problem, we propose a privacy-preserving contact tracing method based on spatio-temporal trajectory which can be practically used in many quarantine systems. In addition, we develop a system to visualize the contact tracing workflow.</span></p><p style="text-align: justify; " align="justify"><span style="color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt; background-color: rgb(255, 255, 255);">&nbsp;</span></p><p style="text-align: justify; " align="justify"><span style="color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt; background-color: rgb(255, 255, 255);">[참고] 동아일보,"</span><font color="#202020" face="나눔고딕코딩, NanumGothicCoding, sans-serif"><span style="font-size: 14.6667px;"><a href="https://www.donga.com/news/People/article/all/20201214/104427008/1" target="_blank">개인 동선 등 사생활 노출없이 감염 의심자 탐색 기술 개발</a></span></font><span style="background-color: rgb(255, 255, 255); color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt;">"(2020.12.14</span><span style="background-color: rgb(255, 255, 255); color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt;">)</span></p><p style="text-align: justify; " align="justify"><span style="background-color: rgb(255, 255, 255); color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt;">&nbsp;</span></p><p style="text-align: justify; " align="justify"><span style="background-color: rgb(255, 255, 255); color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt;"></span></p><p style="text-align: justify; " align="justify"><font color="#202020" face="나눔고딕코딩, NanumGothicCoding, sans-serif"><span style="font-size: 14.6667px; color: rgb(58, 50, 195);">※ 자세한 내용은 링크를 참고하시기 바랍니다.</span></font></p><div style="text-align: justify;"><br></div><p style="text-align: justify; " align="justify"><span style="color: rgb(32, 32, 32); font-family: 나눔고딕코딩, NanumGothicCoding, sans-serif; font-size: 11pt; background-color: rgb(255, 255, 255);">&nbsp;</span></p>
