To slow down the spread of COVID-19, governments around the world are trying\nto identify infected people and to contain the virus by enforcing isolation and\nquarantine. However, it is difficult to trace people who came into contact with\nan infected person, which causes widespread community transmission and mass\ninfection. To address this problem, we develop an e-government Privacy\nPreserving Mobile and Fog computing framework entitled PPMF that can trace\ninfected and suspected cases nationwide. We use personal mobile devices with\ncontact tracing app and two types of stationary fog nodes, named Automatic Risk\nCheckers (ARC) and Suspected User Data Uploader Node (SUDUN), to trace\ncommunity transmission alongside maintaining user data privacy. Each user's\nmobile device receives a Unique Encrypted Reference Code (UERC) when\nregistering on the central application. The mobile device and the central\napplication both generate Rotational Unique Encrypted Reference Code (RUERC),\nwhich broadcasted using the Bluetooth Low Energy (BLE) technology. The ARCs are\nplaced at the entry points of buildings, which can immediately detect if there\nare positive or suspected cases nearby. If any confirmed case is found, the\nARCs broadcast pre-cautionary messages to nearby people without revealing the\nidentity of the infected person. The SUDUNs are placed at the health centers\nthat report test results to the central cloud application. The reported data is\nlater used to map between infected and suspected cases. Therefore, using our\nproposed PPMF framework, governments can let organizations continue their\neconomic activities without complete lockdown.\n
