Like other countries and governments, Singapore has launched an official application to try to help stop the coronavirus from spreading. In addition to confinement, closure of any non-essential business or service, and all other proposed measures, any additional assistance such as this is good.
The TraceTogether app, developed by the Singapore Ministry of Health, aims to track as accurately as possible the range of infection that COVID-19 victims have been able to achieve through the use of Bluetooth signals between their users.
How does TraceTogether work?
Bluetooth signals between users who have the application record interactions between nearby devices. Thus, if someone confirms that they have had contact with an infected person, the Ministry of Health will be able to know precisely who has been close enough to them to be at risk and will be able to guide and help them if they need additional care.
Of course, tracking will be stopped as the epidemic decreases and Bluetooth proximity data is encrypted and stored only on the user's device.
