NHS shuns Apple and Google’s Covid-19 tracking app proposal

The National Health Service (NHS) will reject the coronavirus contract-tracing model proposed by Apple and Google, despite ongoing privacy concerns. 

Both Apple and Google believe a more decentralised approach will protect users’ privacy from authorities and hackers, but the NHS disagrees, and says a centralised approach is necessary.

A centralised model means users’ data will be stored on a computer server, which can then be used to determine which phones need to be sent alerts. This differs from Apple and Google’s approach, where the matches and data required to send out alerts would take place entirely on users’ handsets.

Both Google and Apple believe its approach is preferable, as it prevents the data being mishandled by authorities or from being exploited by hackers. 

The NHS’ approach aligns with many of its EU counterparts – as well as Australia, which recently released its own app. Germany, Austria, Estonia and Switzerland, meanwhile, are now pursuing a more decentralised architecture.

How does the app work?

Contact-tracing apps notify you if you’re at risk of infection, based on whether you’ve come into contact with someone who was recently diagnosed with coronavirus. For example, if you took the tube to work and someone registered themselves as being infected a few days later, a number of alerts will be sent to everyone that the infected person may have passed it on to. 

The NHSX, the health service’s digital innovation unit, has opted to use Bluetooth transmissions to keep track of users interactions, and alerts will be sent anonymously, so you won’t know who triggered them.

Battery life also needs to be considered with either approach, as it could deter users from using the app. Each proposal uses a very different system: Apple will let its phones exchange information with other devices without needing to wake them up at all. The NHS’ solution, however, involves waking the app in the background each time your phone detects another device running the contract-tracing software, which could drain a phone’s battery more quickly. 

Apple and Google are expected to release their contact-tracing API software to developers this week. We’ll have to see which approach works best when the NHS and other national health services release tracking apps in the near future.
