UK eyeing switch to Apple-Google API for coronavirus contacts tracing — report

The UK may be rethinking its decision to shun Apple and Google’s API for its national coronavirus contacts tracing app, according to the Financial Times, which reported yesterday that the government is paying an IT supplier to investigate whether it can integrate the tech giants’ approach after all.

As we’ve reported before coronavirus contacts tracing apps are a new technology which aims to repurpose smartphones’ Bluetooth signals and device proximity to try to estimate individuals’ infection risk.

The UK’s forthcoming app, called NHS COVID-19, has faced controversy because it’s being designed to use a centralized app architecture. This means developers are having to come up with workarounds for platform limitations on background access to Bluetooth as the Apple-Google cross-platform API only works with decentralized systems.

The choice of a centralized app architecture has also raised concerns about the impact of such an unprecedented state data grab on citizens’ privacy and human rights, and the risk of state ‘mission creep‘.

The UK also looks increasingly isolated in its choice in Europe after the German government opted to switch to a decentralized model, joining several other European countries that have said they will opt for a p2p approach, including Estonia, Ireland and Switzerland.

In the region, France remains the other major backer of a centralized system for its forthcoming coronavirus contacts tracing app, StopCovid.

Apple and Google, meanwhile, are collaborating on a so-called “exposure notification” API for national coronavirus contacts tracing apps. The API is slated to launch this month and is designed to remove restrictions that could interfere with how contact events are logged. However it’s only available for apps that don’t hold users’ personal data on central servers and prohibits location tracking, with the pair emphasizing that their system is designed to put privacy at the core.

Yesterday the FT reported that NHSX, the digital transformation branch of UK’s National Health Service, has awarded a £3.8M contract to the London office of Zuhlke Engineering, a Switzerland-based IT development firm which was involved in developing the initial version of the NHS COVID-19 app.

The contract includes a requirement to “investigate the complexity, performance and feasibility of implementing native Apple and Google contact tracing APIs within the existing proximity mobile application and platform”, per the newspaper’s report.

The work is also described as a “two week timeboxed technical spike”, which the FT suggests means it’s still at a preliminary phase — thought it also notes the contract includes a deadline of mid-May.

The contracted work was due to begin yesterday, per the report.

We’ve reached out to Zuhlke for comment. Its website describes the company as “a strong solutions partner” that’s focused on projects related to digital product delivery; cloud migration; scaling digital platforms; and the Internet of Things.

We also put questions arising from the FT report to NHSX.

At the time of writing the unit had not responded but yesterday a spokesperson told the newspaper: “We’ve been working with Apple and Google throughout the app’s development and it’s quite right and normal to continue to refine the app.”

The specific technical issue that appears to be causing concern relates to a workaround the developers have devised to try to circumvent platform limitations on Bluetooth that’s intended to wake up phones when the app itself is not being actively used in order that the proximity handshakes can still be carried out (and contacts events properly logged).

Thing is, if any of the devices fail to wake up and emit their identifiers so other nearby devices can log their presence there will be gaps in the data. Which, in plainer language, means the app might miss some close encounters between users — and therefore fail to notify some people of potential infection risk.

Recent reports have suggested the NHSX workaround has a particular problem with iPhones not being able to wake up other iPhones. And while Google’s Android OS is the more dominant platform in the UK (running on circa ~60% of smartphones, per Kantar) there will still be plenty of instances of two or more iPhone users passing near each other. So if their apps fail to wake up they won’t exchange data and those encounters won’t be logged.

On this, the FT quotes one person familiar with the NHS testing process who told it the app was able to work in the background in most cases, except when two iPhones were locked and left unused for around 30 minutes, and without any Android devices coming within 60m of the devices. The source also told it that bringing an Android device running the app close to the iPhone would “wake up” its Bluetooth connection.

Clearly, the government having to tell everyone in the UK to use an Android smartphone not an iPhone wouldn’t be a particularly palatable political message.

This is effectively a form of Android Herd Immunity: for the good of Britain, vaccinate your friends by giving them Androids!

One source with information about the NHSX testing process told us the unit has this week been asking IT suppliers for facilities or input on testing environments with “50-100 Bluetooth devices of mixed origin”, to help with challenges in testing the Bluetooth exchanges — which raises questions about how extensively this core functionality has been tested up to now. (Again, we’ve put questions to the NHSX about testing and will update this report with any response.)

Work on planning and developing the NHS COVID-19 app began March 7, according to evidence given to a UK parliamentary committee by the NHSX CEO’s, Matthew Gould, last month.

Gould has also previously suggested that the app could be “technically” ready to launch in as little as two or three weeks time from now. While a limited geographical trial of the app kicked off this week in the Isle of Wight. Prior to that, an alpha version of the app was tested at an RAF base involving staff carrying out simulations of people going shopping, per a BBC report last month.

Gould faced questions over the choice of centralized vs decentralized app architecture from the human rights committee earlier this week. He suggested then that the government is not “locked” to the choice — telling the committee: “We are constantly reassessing which approach is the right one — and if it becomes clear that the balance of advantage lies in a different approach then we will take that different approach. We’re not irredeemably wedded to one approach; if we need to shift then we will… It’s a very pragmatic decision about what approach is likely to get the results that we need to get.”

However it’s unclear how quickly such a major change to app architecture could be implemented, given centralized vs decentralized systems work in very different ways.

Additionally, such a big shift — more than two months into the NHSX’s project — seems, at such a late stage, as if it would be more closely characterized as a rebuild, rather than a little finessing (as suggested by the NHSX spokesperson’s remark to the FT vis-a-vis ‘refining’ the app).

In related news today, Reuters reports that Colombia has pulled its own coronavirus contacts tracing app after experiencing glitches and inaccuracies. The app had used alternative technology to power contacts logging via Bluetooth and wi-fi. A government official told the news agency it aims to rebuild the system and may now use the Apple-Google API.

Australia has also reported Bluetooth related problems with its national coronavirus app. And has also been reported to be moving towards adopting the Apple-Google API.

While, Singapore, the first country to launch a Bluetooth app for coronavirus contacts tracing, was also the first to run into technical hitches related to platform limits on background access — likely contributing to low download rates for the app (reportedly below 20%).

UK report highlights changing gadget habits — and our need for an online fix

A look back at the past decade of consumer technology use in the UK has shone a light on changing gadget habits, underlining how Brits have gone from being smartphone dabblers back in 2008 when a top-of-the-range smartphone cost ~£500 to true addicts in today’s £1k+ premium smartphone era.

The report also highlights what seems to be, at times, a conflicted relationship between Brits and the Internet.

While nine in ten people in the UK have home access to the Internet, here in 2018, some web users report feeling being online is a time-sink or a constraint on their freedom.

But even more said they feel lost or bored without it.

Over the past decade the Internet looks to have consolidated its grip on the spacetime that boredom occupied for the less connected generations that came before.

The overview comes via regulator Ofcom’s 2018 Communications Market report. The full report commenting on key market developments in the country’s communications sector is a meaty, stat and chart-filled read.

The regulator has also produced a 30-slide interactive version this year.

Commenting on the report findings in a statement, Ian Macrae, Ofcom’s director of market intelligence, said: “Over the last decade, people’s lives have been transformed by the rise of the smartphone, together with better access to the Internet and new services. Whether it’s working flexibly, keeping up with current affairs or shopping online, we can do more on the move than ever before.

“But while people appreciate their smartphone as their constant companion, some are finding themselves feeling overloaded when online, or frustrated when they’re not.”

We’ve pulled out some highlights from the report below…

  • Less than a fifth (17%) of UK citizens owned a smartphone a decade ago; the figure now stands at 78% — and a full 95% of 16-24 year-olds. So, yeah, kids don’t get called digital natives for nothin’
  • People in the UK check their smartphones, on average, every 12 minutes of the waking day. (‘Digital wellbeing’ tools clearly have their work cut out to kick against this grain… )
  • Ofcom found that two in five adults (40%) first look at their phone within five minutes of waking up (rising to 65% of the under 35s). While around a third (37%) of adults check their phones five minutes before lights out (again rising to 60% of under-35s). Shame it didn’t also ask how well people are sleeping
  • Contrary to a decade ago, most UK citizens say they need and expect a constant Internet connection wherever they go. Two thirds of adults (64%) say it’s an essential part of their life. One in five adults (19%) say they spend more than 40 hours a week online, up from 5% just over ten years ago
  • Three quarters (74%) of people say being online keeps them close to friends and family. Two fifths (41%) say it enables them to work more flexibly

Smartphone screen addicts, much?

  • Seventy-two per cent of adults say their smartphone is their most important device for accessing the Internet; 71% say they never turn off their phone; and 78% say they could not live without it
  • Ofcom found the amount of time Brits spend making phone calls from mobiles has fallen for the first time — using a mobile for phone calls is only considered important by 75% of smartphone users vs 92% who consider web browsing on a smartphone to be important (and indeed the proportion of people accessing the Internet on their mobile has increased from 20% almost a decade ago to 72% in 2018)
  • The average amount of time spent online on a smartphone is 2 hours 28 minutes per day. This rises to 3 hours 14 minutes among 18-24s

Social and emotional friction, plus the generation gap…

  • On the irritation front, three quarters of people (76%) find it annoying when someone is listening to music, watching videos or playing games loudly on public transport; while an impressive 81% object to people using their phone during meal times
  • TV is another matter though. The majority (53%) of adults say they are usually on their phone while watching TV with others. There’s a generation gap related to social acceptance of this though: With a majority (62%) of people over the age of 55 thinking it’s unacceptable — dropping to just two in ten (21%) among those aged 18-34
  • Ofcom also found that significant numbers of people saying the online experience has negative effects. Fifteen per cent agree it makes them feel they are always at work, and more than half (54%) admit that connected devices interrupt face-to-face conversations with friends and family — which does offer a useful counterpoint to social media giant’s shiny marketing claims that their platforms ‘connect people’ (the truth is more they both connect & disconnect). While more than two in five (43%) also admit to spending too much time online
  • Around a third of people say they feel either cut off (34%) or lost (29%) without the Internet, and if they can’t get online, 17% say they find it stressful. Half of all UK adults (50%) say their life would be boring if they could not access the Internet 
  • On the flip side, a smaller proportion of UK citizens view a lack of Internet access in a positive light. One in ten says they feel more productive offline (interestingly this rises to 15% for 18-34 year-olds); while 10% say they find it liberating; and 16% feel less distracted

The impact of (multifaceted and increasingly powerful and capable) smartphones can also be seen on some other types of gadgets. Though TV screens continue to compel Brits (possibly because they feel it’s okay to keep using their smartphones while sitting in front of a bigger screen… )

  • Ofcom says ownership of tablets (58% of UK households) and games consoles (44% of UK adults) has plateaued in the last three years
  • Desktop PC ownership has declined majorly over the past decade — from a large majority (69%) of households with access in 2008 to less than a third (28%) in 2018
  • As of 2017, smart TVs were in 42% of households — up from just 5% in 2012
  • Smart speakers weren’t around in 2008 but they’ve now carved out a space in 13% of UK households
  • One in five households (20%) report having some wearable tech (smart watches, fitness trackers). So smart speakers look to be fast catching up with fitness bands

BBC mightier than Amazon

  • BBC website visitor numbers overtook those of Amazon in the UK in 2018. Ofcom found the BBC had the third-highest number of users after Google and Facebook
  • Ofcom also found that six in ten people have used next-day delivery for online purchases, but only three in ten have used same-day delivery in 2018. So most Brits are, seemingly, content to wait until tomorrow for ecommerce purchases — rather than demanding their stuff right now

What else are UK citizens getting up to online? More of a spread of stuff than ever, it would appear…

  • Less general browsing/surfing than last year, though it’s still the most popular reported use for Internet activity (69% saying they’ve done this in the past week vs 80% who reported the same in 2017)
  • Sending and receiving email is also still a big deal — but also on the slide (66% reporting doing this in the past week vs 76% in 2017)
  • Social media use is another popular but slightly less so use-case than last year (50% in 2017 down to 45% in 2018). (Though Twitter bucks the trend with a percentage point usage bump (13% -> 14%) though it’s far less popular overall)
  • Instant messaging frequency also dropped a bit (46% -> 41%)
  • As did TV/video viewing online (40% -> 36%), including for watching short video clips (31% to 28%)
  • Online shopping has also dropped a bit in frequency (48% -> 44%)
  • But accessing news has remained constant (36%)
  • Finding health information has seen marginal slight growth (22% -> 23%); ditto has finding/downloading information for work/college (32% -> 33%); using local council/government services (21% -> 23%); and playing games online/interactively (17% -> 18%)
  • Streaming audio services have got a bit more popular (podcasts, we must presume), with 15% reporting using them in the past week in 2017 up to 19% in 2018. Listening to the radio online is also up (13% -> 15%)
  • However uploading/adding content to the Internet has got a bit less popular, though (17% to 15%)

One more thing: Women in the UK are bigger Internet fans than men.

Perhaps contrary to some people’s expectations, women in the UK spend more time online on average than men across almost all age groups, with the sole exception being the over 55s (where the time difference is pretty marginal)…

The BBC will run its first podcast ads, powered by Acast

The BBC will start running ads in its podcasts, thanks to a partnership with podcast publishing and monetization company Acast.

Acast CEO Ross Adams told me that ads will start running later this week, with the BBC including “bumpers” today announcing the imminent ad launch.

“Podcasts are one way we’re reinventing BBC radio to engage younger audiences with our world class content,” said Bob Shennan, director of BBC Radio and Music, in the announcement. “We’re working with established and new talent to produce shows which are informative and entertaining as only the BBC can be. The BBC has been challenged to generate more commercial income to supplement the licence fee and this new deal will contribute to that.”

To be clear, the BBC will remain ad-free in the United Kingdom, where it’s supported by the aforementioned license fee. Adams said one of the things Acast could offer was the ability to make sure ads were only served outside the U.K. (and to account for edge cases like U.K. military bases in other countries).

Adams said Acast will also be providing the BBC with new data about how the podcasts are performing.

“We give them the data and the dashboard to start really doubling down and focusing on podcasting as a medium,” he said.

According the announcement, this will apply to all BBC podcasts outside the U.K. (subject to rights restrictions), including Global News, The Assassination, World Business Report and Radio 4’s In Our Time. Most podcasts will have a single 30-second ad at the beginning, then another at the end.
