REACT: Real-Time Contact Tracing and Risk Monitoring via Privacy-Enhanced Mobile Tracking

Contact tracing is an essential public health tool for controlling epidemic disease outbreaks such as the COVID-19 pandemic. Digital contact tracing using real-time locations or proximity of individuals can be used to significantly speed up and scale up contact tracing. In this demonstration, we present our system, REACT, for REAl-time Contact Tracing and risk monitoring via privacy-enhanced tracking of users' locations. With privacy enhancement that allows users to control and refine the precision with which their information will be collected and used, REACT will enable: 1) contact tracing of individuals who are exposed to infected cases and identification of hot-spot locations, 2) individual risk monitoring based on the locations they visit and their contact with others. In this paper, we demonstrate the procedure of contact tracing using our application and the utility of contact tracing given the protected locations.

Automated summary

Contact tracing is essential in controlling epidemic outbreaks like COVID-19, and systems like REACT can enhance privacy-enabled tracking for real-time monitoring. It helps trace contacts and monitor individual risks while allowing users to control data precision.
