The UK is abandoning its current contact tracing app for Google and Apple’s system
2020-06-18 00:00:00
Everyone’s a critic: The UK’s centralized approach had been criticized by privacy, security, and technical experts on the grounds that it would not work unless it was running constantly in the foreground, and that it could break the country’s data protection laws. So far, the country has been relying on its recently launched manual contact tracing program. However, that too has been plagued by problems, according to the New York Times. In the three weeks since it launched, some contact tracers have failed to reach a single person, while others have mistakenly tried to send patients in England to testing sites in Northern Ireland.
No silver bullet: Both the UK’s now-abandoned app and the Google/Apple model rely on Bluetooth signals to figure out who’s been near each other and for how long. It’s a simple idea but a very complex and technically difficult task. Things like walls, human bodies, or interference from other phones can throw the signal off, rendering the data useless. And there’s also the question of how many people will download the technology. While contact tracing apps don’t need universal adoption to be effective, the more people use them, the better they are.
Long time coming: This decision has been in the cards for weeks. Back on May 6 the Financial Times reported that health chiefs in the UK were going to investigate switching to the Apple/Google system. Since then, the UK’s National Health System has been testing both systems against each other, according to the BBC. There’s no word yet on when the redesigned app will be available for everyone in England. Scotland, Wales, and Northern Ireland have their own devolved health systems and are yet to confirm if they will sign up for it.
