The UK’s contact-tracing app is in trouble

Published

4 years ago

 on

Countries around the world are scrambling to create contact-tracing apps that will help track the spread of COVID-19. But a beta app launched by the UK this week shows the huge challenges they face and, crucially, the difficulty in designing an effective app without the help of the tech giants that make our phones.

The UK is one of the few countries that has chosen to create a contact-tracing app that is incompatible with the contact-tracing API currently being developed by Google and Apple. Instead of decentralizing the data across devices, the UK will pool the information it collects in a single database operated by the National Health Service, or NHS.

The government argues this will provide greater insight into the spread of COVID-19 and allow the NHS to decide which users are most at risk. Privacy advocates, though, warn it creates new avenues for state surveillance. Already, the UK government appears to have undermined prior assurances that it won’t share the data it collects outside the NHS, suggesting other organizations might use the information for public health research in the future. This is something Apple and Google forbid for any app using their API, and another reason the UK has to build its app without the companies’ help.

But in addition to privacy issues, researchers have identified a major problem in the UK’s efforts to build an app without Google and Apple: it simply won’t work as advertised.

The core issue is one familiar to mobile security experts: app permissions. Contact-tracing apps use Bluetooth to create a log of nearby devices using the app, and, by extension, people with whom users have come into contact. When a user is diagnosed with COVID-19 or starts to show symptoms, they notify their app which then pings the devices of those people. Some apps, like the one built by Singapore, constantly broadcast Bluetooth pings to find nearby devices. Others, like the one built by the UK, try to create active Bluetooth pairings or “handshakes.”

The problem is that both Google and Apple restrict how apps can use Bluetooth in iOS and Android. They don’t allow developers to constantly broadcast Bluetooth signals, as that sort of background broadcast has been exploited in the past for targeted advertising. As The Register reports, iOS apps can only send Bluetooth signals when the app is running in the foreground. If your iPhone is locked or you’re not looking at the app, then there’s no signal. The latest versions of Android have similar restrictions, only allowing Bluetooth signals to be sent out for a few minutes after an app has closed. Such restrictions will block devices from pinging one another in close quarters, drastically reducing the effectiveness of any contact-tracing app.

 

 

 

Google and Apple can rewrite these rules for their own contact-tracing API because they control the operating systems. But for countries trying to go it alone, like the UK, the restrictions could literally be fatal. iPhone users with the app installed could interact with someone who is later diagnosed with COVID-19 and never know it, if their phone doesn’t keep a log of their interaction.

The UK government has implied it’s created some unknown workaround to these issues, and there certainly are subtleties in how these protocols operate that might work in its favor. For example, while iOS devices can’t broadcast Bluetooth signals constantly, they can receive them from older Android devices. Doing so would essentially wake up the software and allow the app to exchange vital data.

It’s possible to argue, then, that the UK app will work in urban environments where there are a mix of old and new iOS and Android devices constantly in use. But experts say this is a long way from a reliable mechanism necessary to trace the spread of a deadly disease, especially considering that the market share of iOS in the UK is more than 50 percent.

Speaking to The Verge, digital rights expert Michael Veale, who is also part of an international consortium developing decentralized contact-tracing protocols, says there really is no way to build a contract-tracing system without the help of Apple and Google, who he praised for working at “lightning speed” on the issue. “They’ve been moving much faster than we’d expect them to,” he said. “They’ve provided a unified way that works across borders [and] that lots of countries are using.”

But exactly how the UK’s problems will play out is impossible to predict. The beta contact-tracing app is only launching as a small pilot this week in the Isle of Wight, an island with a population of 141,000 off the south coast of England. The UK government still has time to tweak its functionality or switch to a decentralized system, just as Germany did last month. For as coronavirus has shown, although every country has to fight its own idiosyncratic battle with the virus, that doesn’t stop them learning from others.

“The alternative to working with [Google and Apple] is to create a system that doesn’t work on iPhones, that leads to centralized databases that destroy trust, and that doesn’t work across borders and so won’t help open up international travel,” says Veale. “This is the British problem.”

Slack researcher discusses the fear, loathing and excitement surrounding AI in the workplace

SAN FRANCISCO (AP) — Artificial intelligence‘s recent rise to the forefront of business has left most office workers wondering how often they should use the technology and whether a computer will eventually replace them.

Those were among the highlights of a recent study conducted by the workplace communications platform Slack. After conducting in-depth interviews with 5,000 desktop workers, Slack concluded there are five types of AI personalities in the workplace: “The Maximalist” who regularly uses AI on their jobs; “The Underground” who covertly uses AI; “The Rebel,” who abhors AI; “The Superfan” who is excited about AI but still hasn’t used it; and “The Observer” who is taking a wait-and-see approach.

Only 50% of the respondents fell under the Maximalist or Underground categories, posing a challenge for businesses that want their workers to embrace AI technology. The Associated Press recently discussed the excitement and tension surrounding AI at work with Christina Janzer, Slack’s senior vice president of research and analytics.

Q: What do you make about the wide range of perceptions about AI at work?

A: It shows people are experiencing AI in very different ways, so they have very different emotions about it. Understanding those emotions will help understand what is going to drive usage of AI. If people are feeling guilty or nervous about it, they are not going to use it. So we have to understand where people are, then point them toward learning to value this new technology.

Q: The Maximalist and The Underground both seem to be early adopters of AI at work, but what is different about their attitudes?

A: Maximalists are all in on AI. They are getting value out of it, they are excited about it, and they are actively sharing that they are using it, which is a really big driver for usage among others.

The Underground is the one that is really interesting to me because they are using it, but they are hiding it. There are different reasons for that. They are worried they are going to be seen as incompetent. They are worried that AI is going to be seen as cheating. And so with them, we have an opportunity to provide clear guidelines to help them know that AI usage is celebrated and encouraged. But right now they don’t have guidelines from their companies and they don’t feel particularly encouraged to use it.

Overall, there is more excitement about AI than not, so I think that’s great We just need to figure out how to harness that.

Q: What about the 19% of workers who fell under the Rebel description in Slack’s study?

A: Rebels tend to be women, which is really interesting. Three out of five rebels are women, which I obviously don’t like to see. Also, rebels tend to be older. At a high level, men are adopting the technology at higher rates than women.

Q: Why do you think more women than men are resisting AI?

A: Women are more likely to see AI as a threat, more likely to worry that AI is going to take over their jobs. To me, that points to women not feeling as trusted in the workplace as men do. If you feel trusted by your manager, you are more likely to experiment with AI. Women are reluctant to adopt a technology that might be seen as a replacement for them whereas men may have more confidence that isn’t going to happen because they feel more trusted.

Q: What are some of the things employers should be doing if they want their workers to embrace AI on the job?

A: We are seeing three out of five desk workers don’t even have clear guidelines with AI, because their companies just aren’t telling them anything, so that’s a huge opportunity.

Another opportunity to encourage AI usage in the open. If we can create a culture where it’s celebrated, where people can see the way people are using it, then they can know that it’s accepted and celebrated. Then they can be inspired.

The third thing is we have to create a culture of experimentation where people feel comfortable trying it out, testing it, getting comfortable with it because a lot of people just don’t know where to start. The reality is you can start small, you don’t have to completely change your job. Having AI write an email or summarize content is a great place to start so you can start to understand what this technology can do.

Q: Do you think the fears about people losing their jobs because of AI are warranted?

A: People with AI are going to replace people without AI.

Biden administration to provide $325 million for new Michigan semiconductor factory

WASHINGTON (AP) — The Biden administration said Tuesday that it would provide up to $325 million to Hemlock Semiconductor for a new factory, a move that could help give Democrats a political edge in the swing state of Michigan ahead of election day.

The funding would support 180 manufacturing jobs in Saginaw County, where Republicans and Democrats were neck-in-neck for the past two presidential elections. There would also be construction jobs tied to the factory that would produce hyper-pure polysilicon, a building block for electronics and solar panels, among other technologies.

Commerce Secretary Gina Raimondo said on a call with reporters that the funding came from the CHIPS and Science Act, which President Joe Biden signed into law in 2022. It’s part of a broader industrial strategy that the campaign of Vice President Kamala Harris, the Democratic nominee, supports, while Republican nominee Donald Trump, the former president, sees tariff hikes and income tax cuts as better to support manufacturing.

“What we’ve been able to do with the CHIPS Act is not just build a few new factories, but fundamentally revitalize the semiconductor ecosystem in our country with American workers,” Raimondo said. “All of this is because of the vision of the Biden-Harris administration.”

A senior administration official said the timing of the announcement reflected the negotiating process for reaching terms on the grant, rather than any political considerations. The official insisted on anonymity to discuss the process.

After site work, Hemlock Semiconductor plans to begin construction in 2026 and then start production in 2028, the official said.

Running in 2016, Trump narrowly won Saginaw County and Michigan as a whole. But in 2020 against Biden, both Saginaw County and Michigan flipped to the Democrats.

The Internet is Littered in ‘Educated Guesses’ Without the ‘Education’

Published

By

Although no one likes a know-it-all, they dominate the Internet.

The Internet began as a vast repository of information. It quickly became a breeding ground for self-proclaimed experts seeking what most people desire: recognition and money.

Today, anyone with an Internet connection and some typing skills can position themselves, regardless of their education or experience, as a subject matter expert (SME). From relationship advice, career coaching, and health and nutrition tips to citizen journalists practicing pseudo-journalism, the Internet is awash with individuals—Internet talking heads—sharing their “insights,” which are, in large part, essentially educated guesses without the education or experience.

The Internet has become a 24/7/365 sitcom where armchair experts think they’re the star.

Not long ago, years, sometimes decades, of dedicated work and acquiring education in one’s field was once required to be recognized as an expert. The knowledge and opinions of doctors, scientists, historians, et al. were respected due to their education and experience. Today, a social media account and a knack for hyperbole are all it takes to present oneself as an “expert” to achieve Internet fame that can be monetized.

On the Internet, nearly every piece of content is self-serving in some way.

The line between actual expertise and self-professed knowledge has become blurry as an out-of-focus selfie. Inadvertently, social media platforms have created an informal degree program where likes and shares are equivalent to degrees. After reading selective articles, they’ve found via and watching some TikTok videos, a person can post a video claiming they’re an herbal medicine expert. Their new “knowledge,” which their followers will absorb, claims that Panda dung tea—one of the most expensive teas in the world and isn’t what its name implies—cures everything from hypertension to existential crisis. Meanwhile, registered dietitians are shaking their heads, wondering how to compete against all the misinformation their clients are exposed to.

More disturbing are individuals obsessed with evangelizing their beliefs or conspiracy theories. These people write in-depth blog posts, such as Elvis Is Alive and the Moon Landings Were Staged, with links to obscure YouTube videos, websites, social media accounts, and blogs. Regardless of your beliefs, someone or a group on the Internet shares them, thus confirming your beliefs.

Misinformation is the Internet’s currency used to get likes, shares, and engagement; thus, it often spreads like a cosmic joke. Consider the prevalence of clickbait headlines:

  • You Won’t Believe What Taylor Swift Says About Climate Change!
  • This Bedtime Drink Melts Belly Fat While You Sleep!
  • In One Week, I Turned $10 Into $1 Million!

Titles that make outrageous claims are how the content creator gets reads and views, which generates revenue via affiliate marketing, product placement, and pay-per-click (PPC) ads. Clickbait headlines are how you end up watching a TikTok video by a purported nutrition expert adamantly asserting you can lose belly fat while you sleep by drinking, for 14 consecutive days, a concoction of raw eggs, cinnamon, and apple cider vinegar 15 minutes before going to bed.

Our constant search for answers that’ll explain our convoluted world and our desire for shortcuts to success is how Internet talking heads achieve influencer status. Because we tend to seek low-hanging fruits, we listen to those with little experience or knowledge of the topics they discuss yet are astute enough to know what most people want to hear.

There’s a trend, more disturbing than spreading misinformation, that needs to be called out: individuals who’ve never achieved significant wealth or traded stocks giving how-to-make-easy-money advice, the appeal of which is undeniable. Several people I know have lost substantial money by following the “advice” of Internet talking heads.

Anyone on social media claiming to have a foolproof money-making strategy is lying. They wouldn’t be peddling their money-making strategy if they could make easy money.

Successful people tend to be secretive.

Social media companies design their respective algorithms to serve their advertisers—their source of revenue—interest; hence, content from Internet talking heads appears most prominent in your feeds. When a video of a self-professed expert goes viral, likely because it pressed an emotional button, the more people see it, the more engagement it receives, such as likes, shares and comments, creating a cycle akin to a tornado.

Imagine scrolling through your TikTok feed and stumbling upon a “scientist” who claims they can predict the weather using only aluminum foil, copper wire, sea salt and baking soda. You chuckle, but you notice his video got over 7,000 likes, has been shared over 600 times and received over 400 comments. You think to yourself, “Maybe this guy is onto something.” What started as a quest to achieve Internet fame evolved into an Internet-wide belief that weather forecasting can be as easy as DIY crafts.

Since anyone can call themselves “an expert,” you must cultivate critical thinking skills to distinguish genuine expertise from self-professed experts’ self-promoting nonsense. While the absurdity of the Internet can be entertaining, misinformation has serious consequences. The next time you read a headline that sounds too good to be true, it’s probably an Internet talking head making an educated guess; without the education seeking Internet fame, they can monetize.
