국내 연구진, 사생활 침해 없애고 더 똑똑해진 '동선 앱' 개발<br /><br />South Korean health authorities have been praised for their transparency over COVID-19 infection routes and locations.<br />Much of the information is spread online in an instant.<br />However, due to concerns that people's privacy is being encroached upon, researchers have developed a new method.<br />Choi Won-jong has the details.<br />South Korean researchers have taken it upon themselves to develop a new COVID-19 tracking system.<br />KAIST, one of the country's top science and engineering universities, has developed a new, but discreet smartphone app that inform users about the various routes taken by COVID-19 patients.<br />Using the app, citizens can easily and quickly avoid or move away from certain locations.<br />This is how the app works.<br />If a person stays for more than 20 minutes at a distance of 2 to 3 meters from a COVID-19 patient, 50 points will be added out of a maximum of 100, and the score goes up if the person gets even closer.<br />People can know whether they've been in close contact with a COVID-19 patient by simply looking at the score on their phone.<br />This avoids people spreading the names of certain businesses that might've been exposed to an infected patient.<br />This app uses signals from smartphones such as GPS, Wi-Fi and Bluetooth and is able to confirm contact tracing routes, even inside buildings, but it doesn't show the user the location of where the contact may have happened.<br />"Exposure to infectious diseases usually occurs indoors. Using Wi-Fi, Bluetooth or inertia sensory signals, we can more accurately and quickly work out what's happening inside."<br />The researchers will keep developing the app and discuss it with health authorities for possible future widespread use in this age of COVID-19.<br />Choi Won-jong, Arirang News.<br />
