The UK’s contact-tracing app is in trouble

Published

 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.”

Ottawa orders TikTok’s Canadian arm to be dissolved

Published

 on

 

The federal government is ordering the dissolution of TikTok’s Canadian business after a national security review of the Chinese company behind the social media platform, but stopped short of ordering people to stay off the app.

Industry Minister François-Philippe Champagne announced the government’s “wind up” demand Wednesday, saying it is meant to address “risks” related to ByteDance Ltd.’s establishment of TikTok Technology Canada Inc.

“The decision was based on the information and evidence collected over the course of the review and on the advice of Canada’s security and intelligence community and other government partners,” he said in a statement.

The announcement added that the government is not blocking Canadians’ access to the TikTok application or their ability to create content.

However, it urged people to “adopt good cybersecurity practices and assess the possible risks of using social media platforms and applications, including how their information is likely to be protected, managed, used and shared by foreign actors, as well as to be aware of which country’s laws apply.”

Champagne’s office did not immediately respond to a request for comment seeking details about what evidence led to the government’s dissolution demand, how long ByteDance has to comply and why the app is not being banned.

A TikTok spokesperson said in a statement that the shutdown of its Canadian offices will mean the loss of hundreds of well-paying local jobs.

“We will challenge this order in court,” the spokesperson said.

“The TikTok platform will remain available for creators to find an audience, explore new interests and for businesses to thrive.”

The federal Liberals ordered a national security review of TikTok in September 2023, but it was not public knowledge until The Canadian Press reported in March that it was investigating the company.

At the time, it said the review was based on the expansion of a business, which it said constituted the establishment of a new Canadian entity. It declined to provide any further details about what expansion it was reviewing.

A government database showed a notification of new business from TikTok in June 2023. It said Network Sense Ventures Ltd. in Toronto and Vancouver would engage in “marketing, advertising, and content/creator development activities in relation to the use of the TikTok app in Canada.”

Even before the review, ByteDance and TikTok were lightning rod for privacy and safety concerns because Chinese national security laws compel organizations in the country to assist with intelligence gathering.

Such concerns led the U.S. House of Representatives to pass a bill in March designed to ban TikTok unless its China-based owner sells its stake in the business.

Champagne’s office has maintained Canada’s review was not related to the U.S. bill, which has yet to pass.

Canada’s review was carried out through the Investment Canada Act, which allows the government to investigate any foreign investment with potential to might harm national security.

While cabinet can make investors sell parts of the business or shares, Champagne has said the act doesn’t allow him to disclose details of the review.

Wednesday’s dissolution order was made in accordance with the act.

The federal government banned TikTok from its mobile devices in February 2023 following the launch of an investigation into the company by federal and provincial privacy commissioners.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Google’s partnership with AI startup Anthropic faces a UK competition investigation

Published

 on

 

LONDON (AP) — Britain’s competition watchdog said Thursday it’s opening a formal investigation into Google’s partnership with artificial intelligence startup Anthropic.

The Competition and Markets Authority said it has “sufficient information” to launch an initial probe after it sought input earlier this year on whether the deal would stifle competition.

The CMA has until Dec. 19 to decide whether to approve the deal or escalate its investigation.

“Google is committed to building the most open and innovative AI ecosystem in the world,” the company said. “Anthropic is free to use multiple cloud providers and does, and we don’t demand exclusive tech rights.”

San Francisco-based Anthropic was founded in 2021 by siblings Dario and Daniela Amodei, who previously worked at ChatGPT maker OpenAI. The company has focused on increasing the safety and reliability of AI models. Google reportedly agreed last year to make a multibillion-dollar investment in Anthropic, which has a popular chatbot named Claude.

Anthropic said it’s cooperating with the regulator and will provide “the complete picture about Google’s investment and our commercial collaboration.”

“We are an independent company and none of our strategic partnerships or investor relationships diminish the independence of our corporate governance or our freedom to partner with others,” it said in a statement.

The U.K. regulator has been scrutinizing a raft of AI deals as investment money floods into the industry to capitalize on the artificial intelligence boom. Last month it cleared Anthropic’s $4 billion deal with Amazon and it has also signed off on Microsoft’s deals with two other AI startups, Inflection and Mistral.
