SEOUL: When a person in Seoul examined optimistic for the brand new coronavirus in Could, South Korean authorities had been in a position to verify his wide-ranging actions in and outdoors town in minutes, together with 5 bars and golf equipment he visited on a current evening out.
The quick response nicely forward of many different international locations dealing with outbreaks was the results of merging South Korea’s already superior strategies of gathering data and monitoring the virus into a brand new data-sharing system that patches collectively cellphone location knowledge and bank card information.
The Epidemic Investigation Assist System (EISS), launched in late March, successfully eliminated technological obstacles to sharing that data between authorities, by constructing on the nation’s ‘Smart City’ knowledge system.
That platform was initially designed to let native authorities share city planning data, from inhabitants to site visitors and air pollution, by importing knowledge in Excel spreadsheets and different codecs. Now it varieties the inspiration for an information clearinghouse that has turbocharged South Korea’s response to the virus.
Whereas private location and bank card knowledge have been obtainable to be used by South Korean well being investigators for years, earlier programs required bodily paperwork to request the info earlier than it was uploaded to analytical software program.
That took investigators about two to a few days to collect a affected person’s private knowledge to hint their contacts.

The brand new system digitises all the course of, together with the requests, and might cut back that point to lower than an hour, officers say. Investigators can use it to analyse transmission routes and detect seemingly an infection hotspots.
The system has had some teething issues and has attracted criticism on privateness grounds, however it has been a significant factor within the East Asian nation of 52 million protecting virus infections at a comparatively low 11,122, as of Thursday, with simply 264 deaths.
It obtained its first take a look at with an outbreak in Could, traced to the Itaewon district of Seoul recognized for its nightlife, which ended up infecting not less than 206 folks.
“Faster epidemiological survey means the faster discovery of potential patients, which helps contain the spread of the virus even when there’s a massive cluster of infections or people who are asymptomatic, as we’ve seen in the nightclub outbreak,” stated Yoon Duk-hee, director for infectious illness administration in Gyeonggi Province, a densely populated area close to Seoul.
Yoon stated she and different authorities used the EISS to hint the actions of the primary individual detected within the Seoul nightclub outbreak, as he visited various locations together with two nightclubs and three bars.
The system continues to be reliant on people working it to approve and add knowledge, which may result in delays.
And in some circumstances, issues over privateness and safety have led to entry being so restricted that some native officers stated they needed to depend on old school strategies.
When one other contaminated individual – a 25-year-old man referred to as Incheon Affected person 102 – informed well being authorities that he didn’t have a job, metropolis officers stated they went to the police as a result of the data they wished to test was not obtainable in a well timed method on the EISS.
The cellphone’s location knowledge confirmed he was a trainer at a personal academy, the place subsequent contact tracing and testing revealed not less than 30 different folks had been contaminated, together with a few of his college students and their dad and mom.
“There were limitations to the system,” stated an official on the Korea Facilities for Illness Management and Prevention (KCDC), on situation of anonymity as a result of he was not authorised to talk to the media.
“We are now trying to address them after the Itaewon outbreak.”
The EISS was collectively developed by the KCDC and the Ministry of Land, Infrastructure, and Transport, with the assistance of the Korea Electronics Know-how Institute (KETI). Many particulars of how the system works and a few limitations of this system haven’t beforehand been reported.
A scientific paper on the system was printed in a public well being journal solely on Wednesday.
Authorities’ energy to get data was established by a 2015 regulation known as the Infectious Illness Prevention and Management Act, launched after the nation was hit by Center East Respiratory Syndrome (MERS).
The regulation permits South Korean well being officers to entry a variety of private knowledge, together with cellphone location data and bank card transactions, with no court docket order.
Whereas many international locations are scrambling to develop smartphone apps that may hint the contacts of sufferers with out revealing detailed private data, South Korea has solid forward with a extra invasive method.
The EISS permits an authorised investigator to log in to a safe internet portal and ship data requests about particular confirmed circumstances. Police companies should approve requests for location knowledge from three telecommunications operators, whereas the Credit score Finance Affiliation handles approval for data from 22 bank card corporations.
When a request is authorized, designated officers on the corporations obtain alerts on their telephones and computer systems. They then add people’ knowledge in an Excel spreadsheet.
The investigator then has momentary entry to the data to conduct evaluation. There are normally greater than 10,000 location knowledge factors for every individual in a typical 14-day interval being analysed, in response to the KCDC.
An EISS internet portal seen by Reuters confirmed an interactive map displaying affected person actions, with every location knowledge level indicating whether or not it was collected through bank card or cellphone.
The federal government says entry is restricted and authorised investigators should log in by way of a digital non-public community (VPN) and use two-factor authentication to forestall safety breaches.
Officers informed Reuters that builders of the system had thought of utilizing surveillance footage and even facial recognition as a part of the info the system might entry, however determined in opposition to it due to privateness issues. Whereas CCTV is just not accessed or uploaded to the EISS portal, well being investigators nonetheless broadly use such footage to trace circumstances.
“We spent more time agonising over privacy than on developing the system,” stated Park Younger-joon, a director on the KCDC.
Nonetheless, the system has raised issues over its use of personal knowledge.
“It represents a rare non-judicial, non-consensual acquisition of location data, with no judicial oversight for the data collected,” stated Deborah Brown, a digital rights researcher with the US-based Human Rights Watch.
“There’s a concern that the door is open to abuse.”

South Korean officers informed Reuters that knowledge on nearly each individual confirmed to have the virus is entered into the system to permit cross-referencing and evaluation of seemingly hotspots. The KCDC declined to say how many individuals’s knowledge has been collected in all.
Folks wouldn’t have any selection whether or not their knowledge is collected and accessed, however officers informed Reuters that authorities notify anybody whose data is gathered and that every one the info can be deleted when the virus is contained.
“Such information should only be used for crises like infectious diseases,” stated Gyeonggi Province Governor Lee Jae-myung.
“But thankfully our people understand that it is inevitable in battling the pandemic.”
At a nationwide or world stage, lives are extra vital than private privateness, stated a 64-year-old South Korean lady who requested solely to be recognized by her surname Jang. “Personal privacy is important, but preventing infectious disease is even more so.”
Some native well being investigators stated that entry to the EISS has been too restricted or too sluggish, in order that they have gone again to conventional methods of requesting knowledge.
One Incheon well being official informed Reuters town didn’t initially use EISS on Incheon Affected person 102 as a result of it took too lengthy to get the individual registered.
These issues have since been addressed by modifications that will enable native companies to register sufferers themselves moderately than ready for the KCDC, stated Kim Jae-ho, a director at KETI.
Journey data and medical information could also be added to the system, two folks engaged on the undertaking informed Reuters. South Korean well being ministry official Yoon Tae-ho stated at a briefing that also they are using Bluetooth and QR codes to log locations folks go to – comparable to nightclubs.
There was “inertia in the administrative process,” the primary KCDC official informed Reuters.
“But now I am swamped with calls from the local governments about how to use the system.”
