HKBU launches COVID-19 alert system


Professor Guo Yike (right) and Professor Xu Jianliang (left), say the HKBU COVID-19 alert system can protect individuals’ privacy.

HKBU researchers have developed a COVID-19 alert system which will send a message to users through a mobile app if they and an infected person have visited the same place within a time period that gives rise to risks of exposure. The system will not collect users’ personal information and location data, thereby protecting individuals’ privacy while alerting them on disease transmission risks associated with confirmed infection cases.

HKBU plans to launch a trial run of the system on campus in the new semester with the aim of enhancing COVID-19 risks alert capability inside campus venues and during teaching and learning activities. Staff and students can join the trial voluntarily.
