Student app aids Singapore virus tech
Local response based on US high school project
Singapore kicked off a global rush to develop contact tracing apps for the novel coronavirus when the city-state launched a seemingly new system in March.
But the project actually drew inspiration from a 2014 US high school project that won an international prize but found no backers – until now.
It all started when Rohan Suri created an app at Thomas Jefferson High School in Alexandria, Virginia, to alert his mother that she should leave home for the bus stop when he was seven minutes away. As the Ebola epidemic was ravaging western Africa at the time, Suri and schoolmate Claire Scoggins connected the dots between tracking apps and contact tracers who ask patients to whom they may have spread viruses.
“I got really interested in basically automating a lot of these contact tracing efforts,” Suri said, noting staff shortages in remote parts of Africa during the Ebola epidemic.
When Suri and Scoggins developed a prototype called kTrace, they appealed to medical aid organizations and the US government to bring it to the frontlines. But they found no takers, even after winning third place for systems software at the 2015 International Science and Engineering Fair.
The app languished until Suri, now a 21-year-old junior at Stanford University, received an email on January 24 from Jason Bay, a Stanford alumnus and senior director at Singapore’s Government Technology Agency (GovTech).
“My mom had texted me saying, ‘You’ve got to look at this virus in Wuhan and do something about it,’” Suri said, referring to the city in China where the coronavirus outbreak first began. “I didn’t take it seriously, though, and week later the Singapore government is reaching out.”
Bay’s team had been looking for technology to help curb the coronavirus and came across kTrace online. Suri spent February and March volunteering on GovTech’s TraceTogether app alongside fellow Stanford students Nikhil Cheerla and Daniel Lee.
They said they gave Singapore a roadmap by sharing kTrace’s code and providing advice in virtual meetings on stronger privacy protections. They also collected 13 phones to help test Bluetooth technology.
Singapore was “just looking around for any way to speed up the development process and we fit in,” Cheerla said.
The agency said it contacted Suri “to understand his experiences and considerations in designing kTrace for Android.” But Suri “did not commit code to TraceTogether, nor did (GovTech) use kTrace in the development of TraceTogether,” it added.
New project
University scientists Kate Farrahi and Manuel Cebrian said their studies as early as 2011 were the first to show Bluetooth readings could aid contact tracing. They did not develop an app, however, and Suri had not seen their work in high school.
But since Singapore’s app launched, several dozen governments including Australia and the UK, and US states such as North Dakota have among them spent millions of dollars to develop separate tracing apps. Government health authorities administer and promote the apps and link them to their testing systems.
Many other governments are monitoring progress in Singapore, where about 25 percent of the country’s 5.6 million residents have downloaded TraceTogether.
Contact tracing apps largely use anonymous Bluetooth radio exchanges to automatically log nearby users. The technology aims to slow viruses by identifying secondhand infections more quickly than through interviews.
But privacy concerns are a hurdle, and the technology does not work well on iPhones. A fix Apple Inc introduced in partnership with Alphabet Inc’s Google last month limits the personal data contact tracing apps can collect, which authorities say reduces their effectiveness.
Google is adding features on its Maps service to alert users about COVID-19-related travel restrictions to help them plan their trips better, Alphabet Inc said on Monday.
The update would allow users to check how crowded a train station might be at a particular time, or if buses on a certain route are running on a limited schedule, Google said. The new features would also include details on COVID-19 checkpoints and restrictions on crossing national borders, starting with Canada, Mexico and the US.
To fix the data privacy issue, Singapore has adopted a costly solution: giving residents small tracing gadgets, possibly worn on a lanyard, that do not require smartphones.
Suri said he too had developed a wearable device in high school because Ebola infections were highest in countries with low smartphone ownership.
Suri is now focusing on a third app called Zero, aimed at US cities.
The day after TraceTogether launched, a friend who knew about Suri’s involvement introduced him to a handful of New York entrepreneurs and venture capitalists seeking to bring similar technology to the US.
They ended up co-founding Zero, which aims to attract users by bundling contact tracing technology with a safety-rating tool for shops and restaurants based on measures such as occupancy limits and mask rules.
“You need a strategy that goes hyperlocal, and that’s what Zero is doing,” Suri said.
For example, a shopper would check Zero for safety ratings before deciding where to go. Shops could promote special hours through the app for customers who wear masks.
Zero launched for iPhones last week, with its first business listings coming soon in New Rochelle, New York. Contact tracing will be added when cities agree to become partners.
