COVID-19 has been announced as a Global Communal Health Extremity by WHO on Jan 2020. Meaningful preventive solutions have been taken with smartphone selfie/ geofencing apps towards managing mandatory home quarantine and physical distancing. In the post-COVID world, fast screening and strict quarantine can play a crucial role in bringing back normality. Quarantine being offered at home can be a comfortable solution for both Govt and patients. On the other hand, it can be hazardous if not strictly followed and adequately realized. However, the existing geofencing/ face selfie apps take static photographs and location data at certain time intervals that can allow patients to violate the rules between those periods, thus failing to ensure active user identity. To realize un-breached home quarantine policies, this article introduces a CUBAHQM smartphone app that performs continuous user biometric authentication (CUBA) augmented with geofencing using AI technology. The purpose of continuous tracking is to strictly control the spread of infectious diseases in society by monitoring the individual move in/out in the quarantine zone.
