With the pandemic spreading quickly across the globe, the Hong Kong government has issued quarantine orders on people entering the city from all overseas countries and territories.
As a compliance measure, people under quarantine have been required to regularly report their current real-time locations via instant messaging applications or answer surprise video calls from communication centers. This approach incurs high monitoring cost to the government, and brings much inconvenience to the home confines.
In order to achieve significantly higher cost-effectiveness, a team of researchers and engineers has innovated and designed an automated geo-fencing technology called “Signature Home”. The core technology has since been licensed to and deployed by Compathnion Technology Limited as a new mobile app called StayHomeSafe.
The app has been used by the public since March 14 as a more resource-efficient and friendly way to monitor people under home quarantine. Paired with an electronic Bluetooth wristband worn on the quarantined person, the app can accurately detect whether the home confinee is complying with the quarantine order, and alerts the relevant authorities if not.
The key idea of Signature Home geo-fencing technology is that the collective signal variations within a certain location are unique to that location, forming its “signature”. The technology hence collects multifarious environmental signals such as Wi-Fi, Bluetooth and cellular in the dwelling place as its signature.
