Is there a secret Covid tracker on your phone?

Apple and Android users have been left puzzled after a coronavirus tracking software quietly glided on to their mobile phones without consent. 

Despite no prior warning, a function called COVID-19 Exposure Logging has been installed to pave the way for a fully-fledged test and trace app.

Users across the world have slammed the ‘sneaky’ and ‘Orwellian’ way in which the feature suddenly appeared. 

Critics feared it heralded a slippery slope towards data security breaches – concerns which dogged the beleaguered NHS app, which has now been axed.

And people have also blamed the download for a recent spate of glitches as well as killing the phone’s battery life. 

But proponents are simultaneously hailing the technology as a step towards stamping out the virus and ending lockdown.  

The function, which is found on the health section of an iPhone's privacy settings, is automatically disabled and cannot be activated

Despite no public announcement from the government or the phone companies, a function called COVID-19 Exposure Logging has been installed

The function, which is found on the health section of an iPhone’s privacy settings and the Google settings of an Android device, is automatically disabled in countries without contact-tracing apps, such as Britain. 

The feature was built in to phones on May 20, however, because nobody was told, users are only now discovering the function. 

It makes clear it will allow a future app to harness in-built Bluetooth technology and alert the owner if they have been in proximity with someone infected. 

Many are up in arms over the lack of information and even went as far as to brand it a violation of trust.

In countries which have an app, such as Germany, users are claiming it is rapidly sapping their battery life – a complaint with the NHS app, which has now been scrapped.

Ministers pulled the plug on the initial NHS app after it exposed a soup of compatibility problems and privacy concerns. 

Health Secretary Matt Hancock said he had ditched this centralised system and was now working with partners at Apple and Google to build an alternative. 

Contact-tracing infrastructure has been hailed as the route out of a nationwide blanket lockdown as it will only force those exposed to the virus to isolate.

Under fire after the Isle of Wight pilot flopped, Boris Johnson insisted an app was merely one pillar of the UK’s test and trace apparatus, which was mainly formed of physical contact-tracers.

The COVID-19 Exposure Logging function says: ‘When enabled, iPhone can exchange random IDs with other devices using Bluetooth.

‘This enables an app to notify you and you may have been exposed to COVID-19.’

WHAT HAPPENED TO THE NHS CONTACT TRACING APP?

Officials admitted on June 18 that the NHS app, once praised by the Health Secretary as vital for lifting lockdown and described by Boris Johnson as a central part of the UK’s test and trace system, did not work on Apple iPhones.  

The health service’s digital arm, NHSX, has now ditched plans to create its own app and will work with Apple and Google to improve their existing technology. 

Mr Hancock could not say when a tracking app would be ready amid claims it won’t be rolled-out until the winter.   

The app — which was originally promised for mid-May and the NHS spent months to develop — was unable to spot 25 per cent of nearby Android users and a staggering 96 per cent of iPhones in the Isle of Wight trial.

Meanwhile, the Apple and Google technology can spot 99 per cent of close contacts using any type of smartphone — but it cannot currently tell how far away they are, officials claimed today.   

The leaders of Britain’s test and trace system said neither app is fit for purpose and Mr Hancock appeared to point the finger at Apple for the failure, saying: ‘Our app won’t work because Apple won’t change their system’.

Apple and Google announced on April 10 that they would join forces to create the technology, by which time the NHS had already started work. All parties put their software into action around a month later, in mid-May.

Developers in the NHS will now work alongside the tech giants to try and roll its detection software and the NHS app’s distance-measuring ability — which they said was significantly better — together to make a hybrid app that actually works.  

Here’s how the NHS contact tracing app fell apart:

  • When used on iPhones the NHS app went into background mode and stopped recording nearby phones;
  • As a result it only managed to detect four per cent of possible contacts for Apple phone users. In contrast, it detected 75 per cent for Android phone users; 
  • The technology developed by Apple and Google could detect 99 per cent of nearby phones, officials said, but could not say how close they actually were;
  • Health bosses said the Apple/Google technology couldn’t differentiate someone 3m (9’8′) away with their phone in their hand from someone 1m (3’3′) away with it in their pocket;
  • Officials now want to merge the two, to have Apple/Google’s detection capability with the NHSX app’s ability to calculate distance, which was far better.

The way in which the function seems to have crept on to phones without fanfare will likely flare up simmering privacy concerns about how an app will use personal data.

But the function tries to assuage this nervousness and says: ‘Exposure Logging cannot access any data in, or add data to, the Health app.’

It adds: ‘The random IDs your device collects are stored in an exposure log for 14 days.

‘This exposure log allows an app you authorise to notify you if you may have been exposed to COVID-19.’

If someone tests positive for the virus, they will be able to choose whether to share their random ID with the app to be able to notify others. 

Unlike the dropped NHSX app, Apple and Google software is decentralised, so the personal information is not pooled in a central database. 

Instead, phones will use Bluetooth to swap cryptographic key codes when they enter proximity.

If one of the phone owners tests positive, they will record this with the app and trigger an option to share this information with the app.

Ministers are hoping the app will have less holes than the abandoned NHSX version which was unable to monitor close contacts between people if one or both of them were using an iPhone because the phone forced it into sleep mode. 

British officials are now reported to be working with the tech giants to develop a hybrid app using the best features from both.

They said this month that the NHS app didn’t work when used on Apple iPhones – it essentially went into sleep mode and was unable to detect 96 per cent of contacts.

Although it worked better on Android, detecting 75 per cent of phones nearby, it did not compare with the 99 per cent detection achieved by Apple and Google’s software. 

That technology, however, could not tell how far away someone was and produced the same signal for people at three metres as it did for people at one metre.

The amount of time people spend within a certain distance of one another – currently two metres – is ‘mission critical’ for a contact tracing app, Matt Hancock said.

People living in apartment buildings, for example, are likely regularly within three metres of someone but not actually in the same flat or even on the same floor.

NHS bosses now say they will pool the positives of both apps to try and create one which can be used in Britain in the future, but this is likely to take months.

Baroness Dido Harding and Matthew Gould, CEO of NHSX, the health service’s digital department, said in a joint statement: ‘We have agreed to share our own innovative work on estimating distance between app users with Google and Apple – work that we hope will benefit others – while using their solution to address some of the specific technical challenges identified through our rigorous testing.’
