自從 2019 年開始，COVID-19 病毒席捲全球，因而開始研究 許多對付病毒擴散的方法。在所有的方法之中，路徑追蹤為一種 有效掌握疫情現狀，並且減緩疫情擴散速度的一種解決方法。然 而路徑追蹤卻也造成個人隱私外流的問題。在本篇論文之中，將 會介紹一套運用 GPS 的運算方法所構建的 A.C.T.路徑追蹤系統。 此系統將個人隱私資訊進行完整的保護，與此同時也確保路徑追 蹤的精準度，以精準的掌握病患以及接觸者。;COVID-19 has spread around the world rapidly since 2019. Many solutions have been proposed to stop the virus from getting worse. Contact tracing is one of the many solutions to effectively control the pandemic and lessen the speed of the virus spreading. With the popularity of contact tracing, some privacy issues in contact tracing have come to the fore. This research will introduce a new method of contact tracing, A.C.T., which protects the privacy of all the users and more importantly processes the contact tracing accurately.
