16 Apr Nodle Launches Coalition, a Free, Privacy-First Contact Tracing App to Help Stop The Spread of COVID-19
SAN FRANCISCO–(BUSINESS WIRE)–The team behind Nodle.io, an Internet of Things (IoT) connectivity and security startup, today announces the launch of Coalition, a free, privacy-first contact tracing app to help stop the spread of COVID-19. Coalition aims to be an essential preventive tool to protect communities and global citizens during the current COVID-19 crisis. Coalition is now available for Android in the Google Play Store and pending release for iOS in the App Store.
Coalition enables community-driven contact tracing through a privacy-by-design approach. The app utilizes secure Bluetooth Low Energy (BLE) and cryptography to protect a user’s identity by generating random anonymous IDs. Coalition’s Whisper Tracing, an open and privacy-first protocol, randomizes a user’s device identity and does not share identifiable information with the cloud. No personal data is ever asked for, collected or shared. View Coalition’s Whisper Tracing research paper, reviewed by Nodle peers and cryptographers from MIT, Stanford, USC and Oxford University.
“While we have yet to see any plausible global contact tracing solution—mainly due to issues of privacy—we believe the Coalition App could change that with the team’s experience and primary focus on protecting users’ data with a privacy by design approach as described in [the] scientific paper,” said Dr. Newton Howard, D.Phil., HDR, PhD, C.O., M.A., University of Oxford & Georgetown University Medical Center.
How does it work?
After a user downloads the app and turns on Bluetooth, their phone becomes “aware” of other app users within a range of approximately 10 meters. The app records anonymous “encounters” with other Coalition app users nearby. These encounters are stored locally on the phone, using randomly generated IDs to preserve users’ privacy.
If a user declares that they’re sick, their anonymous random IDs from the previous two weeks are uploaded to the cloud.
The Coalition app automatically retrieves these “infected” IDs to compare the IDs on the phone to match if the user was in contact with an infected user.
If there’s a match, the Coalition App notifies the user, indicating the number of possible interactions with an infected user.
The app then recommends that the user check their symptoms and contact their health care provider with any concerns. The user controls whether they share any information with the network; Coalition never shares any personal information without users’ consent.
The Coalition App benefits from decades-long R&D by the Nodle team in the space of decentralized wireless networks, mobile mesh, and secure identity management. Nodle’s CEO & Co-Founder Micha Benoliel previously created FireChat, a peer-to-peer Bluetooth-based “off-the-grid” messaging technology that allowed for communication on planes, cruises, at festivals and during internet shutdowns (see Hong Kong’s 2014 Umbrella Revolution) and disaster-recovery situations where internet isn’t available.
“Our team has the technology to create this type of application with the utmost security and respect for privacy. Every feature is built with privacy and anonymity at its core,” says Benoliel. “We believe the only way to stop COVID-19 is through massive cooperation and solidarity between citizens around the world who can do their part to protect themselves and their communities. We must work fast to put the right safeguards in place before we reopen society and put economies back on track.”
The Whisper Tracing protocol is open and the code from the apps will be open sourced in the coming days so the various tracing apps can communicate with each other and allow the community to make improvements for future use. It is comparable to what Apple and Google announced, with the exception that Coalition has already released a working implementation of its protocol within the Coalition app. The Coalition team mentioned that they would add support for Apple and Google’s protocol if it can increase interoperability, the same way they are also adding support for Singapore’s TraceTogether app.
Coalition is kicking off in the coming week with local leaders in Berkeley, California, through a series of virtual town halls with Mayor Jesse Arreguin and City Councilmember Ben Bartlett. “You have my full support and commitment to help bring this life-saving application to affected communities everywhere,” Bartlett said in his letter of support for the Coalition App.
Operating as a non-profit, Coalition already received interest from several foundations who wish to provide additional financial support to stop the spread of COVID-19. The growing number of partners include Berkeley Blockchain Xcelerator, NY Tech Alliance, TCN Coalition, COVID Alliance, and more.
Coalition’s app and technology were developed by the team behind Nodle, an Internet of Things (IoT) connectivity and security startup, and a few independents. The Nodle founders previously created FireChat, a peer-to-peer Bluetooth-based messaging technology that is used to stay connected and communicate in areas without internet access.
