Discord rolls out encryption for both voice and video calls

Published 24 September 2024
– By Editorial Staff

Gaming communication app Discord has launched the DAVE protocol, a custom point-to-point encryption (E2EE) that protects voice and video calls from unauthorised eavesdropping. This encryption means that no one outside the call, including Discord itself, can access what is said or shown in the video. The goal is to increase security for users.

From 17 September, Discord will begin using end-to-end encryption for audio and video in direct messages, group chats, voice channels and Go Live broadcasts, but text messages between users will not be encrypted, Bleeping Computer reports.

Users will be able to check whether their conversations are encrypted and confirm the identity of other participants in the conversation. There is currently no option to manually enable or disable encryption, but users will be notified when encryption is applied to their calls.

The DAVE protocol, developed with the help of cyber experts at Trail of Bits, is open source, meaning that information about the encryption is available to anyone. Discord hopes to develop and improve the encryption through feedback and criticism from the community, especially from other developers. A white paper with full technical details has also been published to ensure transparency with the community.

Originally created for gamers to communicate while playing games, Discord has grown into one of the world’s most popular communication platforms with over 200 million active users. The introduction of DAVE is a significant step towards improving data security and privacy on a platform that has long lacked encryption.

China launches investigation into Google after Trump’s punitive tariffs

Published 5 February 2025
– By Editorial Staff
Google's attempts to enter the Chinese market have so far been largely unsuccessful.

China’s competition authority has launched an investigation into US tech giant Google. The investigation was announced as tensions between the US and China escalated further after President Donald Trump imposed new punitive tariffs on Chinese goods.

The Chinese State Administration for Market Regulation (SAMR) announced on Tuesday that it had launched an investigation into suspected competition violations by Google. Details of the investigation have not yet been made public, nor have Chinese authorities explicitly linked the action to recent US tariff announcements.

Google has a limited presence in China, where many of its services are blocked by the country’s authorities. Previous attempts to expand in the Chinese market have also failed due to government support for domestic competitors, cybersecurity issues and content moderation requirements – often described in the West as “censorship”.

In recent years, the US search giant has been the subject of widespread criticism and legal proceedings around the world. Last year, a US federal court ruled that Google is acting monopolistically and abusing its dominant position to stifle competition. In the EU, the internet giant has been fined billions of euros for antitrust violations and the UK competition authority recently launched an investigation into Google’s advertising activities.

Export restrictions on key minerals

The Chinese investigation coincides with the latest escalation in the US-China trade war. The Trump administration recently announced the imposition of additional 10% tariffs on Chinese goods. The decision was officially motivated by “emergency solutions” linked to illegal immigration and drug smuggling, but in practice was aimed at China and other trading partners.

Beijing immediately responded by imposing tariffs on US goods such as hydrocarbons, agricultural machinery and vehicles. The Chinese government has also tightened export restrictions on strategic minerals such as tungsten, tellurium, bismuth, molybdenum and indium – which are essential for advanced technology and manufacturing.

Officially, however, these measures have not been motivated by the ongoing trade dispute with the United States.

Privacy 101

Don't know where to begin? Here are 6 steps to get started on your privacy journey!

Regaining the right to consent

In today’s hyper-connected world, the right to control our own information is often stripped away without our knowledge or consent. Companies, data brokers, and governments collect vast amounts of data about us—more than we might imagine.

The good news? We can take back control.

Privacy isn’t about hiding—it’s about reclaiming the right to decide who gets access to our data and how it’s used.

Surveillance apologists normalize invasive practices, but you have the power to push back and reclaim your digital life.

If you’re overwhelmed by where to begin, don’t be. Every small step you take makes a big difference. This guide will help you get started with six simple changes that can significantly improve your daily privacy.

In this guide, I’ve highlighted a few tools I personally use and find effective, but there are so many incredible options available. For a deeper dive, check out our other articles and videos that explore the tradeoffs of other alternatives. If you’ve discovered tools we didn’t mention, share them in the comments so others can benefit from your experience!

6 Simple steps to start reclaiming your privacy

1. Switch Your Browser

Your browser is your gateway to the internet, and it’s often a major source of privacy leaks. Popular browsers like Chrome and Edge collect massive amounts of data about your online activity.

  • Solution: Switch to a privacy-focused browser.
  • Resource: Use privacytests.org to compare browsers and see how they handle tracking and other privacy measures. Some browsers that stand out on the list include Brave, Mullvad, and LibreWolf (with a special mention that goes to Tor, obviously).
  • Steps:
    • Import your bookmarks from your current browser to make the transition seamless.
    • You can also import any saved passwords if that is a barrier to you switching over. Even better is to import any saved passwords directly into a password manager: this is a more involved setup so we have a deep-dive on password managers that we didn’t include in this 6-step introduction.
    • Set your new browser as the default for easy use.

2. Change Your Search Engine

Google Search dominates the market, but it also builds detailed profiles of your interests, habits, and even medical concerns, and countless entities aggregate this data on your and exploit it.

  • Solution: Try privacy-focused search engines, there are countless, including Brave, Mojeek, Metager, SearX, Whoogle, Startpage, Duckduckgo, Swisscows, and Presearch to name a few. Let us know which ones give you the best results!
  • Pro Tip: Make a secondary search engine your browser’s homepage for easy access to multiple options.
  • Why It Matters: Switching search engines is one of the easiest privacy wins—90% of people use Google, so just making this change puts you ahead of the curve.

3. Secure Your Messaging

SMS and regular phone calls are not private. Almost all countries require telecom providers to build backdoors for government surveillance, but these backdoors are exploited.

  • Solution: Use private messaging apps that are E2EE.
  • Resource: Check out securemessagingapps.com for an in-depth comparison of private messaging apps and their features. My favorite is Signal, but you can try out others like Threema, or SimpleX, or whichever stands out to you on the list.

4. Upgrade Your Email

Popular email services like Gmail analyze your inbox to build detailed profiles on you.

  • Solution: Use privacy-focused providers like ProtonMail or Tuta, which offer E2EE in-network, and tools like password-protected emails for anything out-of-network.
  • Steps:
    • Import your Gmail history and contacts into your new email provider for an easy transition – you can do this with a single click.
    • Set up email forwarding from your old account to your new one, gradually transitioning your contacts.

5. Migrate Your Calendar

Your calendar holds sensitive information, including your daily habits, appointments, and locations.

  • Solution: Switch to end-to-end-encrypted calendars from providers like Proton or Tuta.
  • Steps: Import your existing calendar data with just a click, and all your future appointments will now be private and secure.

6. Use a VPN

A VPN encrypts your internet traffic and hides your IP address from the websites you visit, protecting your location and online activities.

  • Solution: Choose reputable providers like Mullvad or ProtonVPN. Be very careful which VPN you download: a large part of the industry are just scam apps run by shell companies that collect you data. Only choose reputable providers.
  • Why It Matters: A VPN adds an extra layer of protection, preventing websites and data brokers from easily profiling you.

Takeaways

Reclaiming your privacy is about taking control of your digital life and asserting your right to choose who gets access to your data.

While it may seem overwhelming at first, the steps outlined in this guide are simple, actionable, and make a huge impact. They’re also quick wins that don’t require technical expertise. Each step builds on the last, making privacy less daunting and more empowering.

Privacy isn’t about perfection or doing everything at once—it’s about progress. By starting small and gradually adopting tools that align with your values, you can reclaim control over your data one step at a time.

This journey is about more than protecting yourself—it’s about building a better, more secure digital world for everyone. Your privacy is worth it, and you’re more capable than you realize.

Take that first step, and you’ll quickly see how much power you really have.

Swedish researchers develop “digital twins” to predict health outcomes

Published 2 February 2025
– By Editorial Staff

A “digital twin” could soon provide insights into how different lifestyle choices affect future health. Research is currently underway at Linköping University to develop digital models of the human body with the aim of promoting health.

For 20 years, Gunnar Cedersund, a lecturer at the Department of Medical Engineering in Linköping, has been working on creating a computer-based model of how the body’s organs function. Today, Cedersund leads a research group aiming to make these “digital twins” a constant health companion throughout life – in the form of an app.

The app is intended to allow the user to input their health data and show how the body would react to changes in habits, both positive and negative. For example, it can simulate the effects of quitting smoking, taking up exercise or starting to take a drug, and give an insight into how future health might be affected by different choices.

Cedersund is currently working with his colleagues to develop digital twins that 300 patients will be able to test in the spring. A central part of the work is to create a basic digital model of the body’s functions, which can then be supplemented with individual data to create a personalized version in the app.

We want to fill it with as much individual data as possible so that it becomes a model of an individual, with that individual’s particular health profile and conditions, says Cedersund to forskning.se.

“See with your own eyes”

The digital twin can also be designed to resemble the user. For example, colleague William Lövfors has created a digital twin that looks like a computer game character based on himself. In the app, he can input lifestyle changes that affect his weight and the digital copy reacts by gaining or losing weight – just as Lövfors would probably do in real life. He points out that this is what sets this technology apart from traditional health advice.

The difference between just getting good advice, like it’s good to exercise and eat lots of fiber and vegetables and so on, is that with this digital twin you can try to make the changes in the computer and see with your own eyes what happens, Lövfors tells the research news site.

The idea is that the app can be automatically updated with data from, for example, activity watches and other wearable sensors.

However, it is not known how people will be affected by using a digital health twin, but researchers stress that they are also working with psychologists and behavioral scientists on the use of the app.

The research group’s goal is for the digital twins to be integrated into basic healthcare, for example, during health consultations offered in one’s 40s and 50s.

Here’s the Chinese AI model that’s shaking up the tech world

Published 31 January 2025
– By Editorial Staff
While OpenAI's GPT-4 was said to have cost over $100 million to train, DeepSeek claims their model only required $6 million.

The Chinese AI model DeepSeek has very quickly become one of the most downloaded apps and attracted a lot of attention in the tech industry. Its unexpected success has not only surprised investors but also affected the market capitalization of several major tech companies.

DeepSeek is an AI-powered chatbot and language model that works in a similar way to OpenAI’s ChatGPT. It is used to generate text, answer questions, and help users with tasks such as coding and mathematical calculations. The model has been compared to OpenAI’s o1 and is considered an advanced reasoning model, allowing it to process complex questions and provide multi-stage answers.

One of the most notable aspects of the chatbot is its low development cost. While OpenAI’s GPT-4 was said to have cost over $100 million to train, DeepSeek claims that their model only required $6 million. This has been made possible by a combination of advanced memory management and the efficient use of less powerful chips, making the model both cheaper and more resource efficient.

DeepSeek is not just a technological innovation, however, but also part of China’s larger strategy to reduce its dependence on Western technology. The company has managed to build a powerful AI model despite an export ban on high-end semiconductor chips from the US.

Major drop for Nvidia

The chatbot’s rapid impact has had immediate effects on the tech market. Among other things, the model has shown that advanced AI solutions can be developed without access to the most powerful chips, which has created uncertainty in the market about the need for expensive semiconductors.

The biggest stock market impact has been seen in Nvidia, the world’s leading chip maker, whose share value fell by $600 billion – the biggest one-day loss in US history. The market has reacted sharply to the realization that cheaper AI models can compete with the most advanced alternatives.

At the same time, DeepSeek, like other AI models, has also raised questions about security and data privacy. Some experts argue that the model, like other AI platforms, may be subject to government censorship and restrictions and that DeepSeek is programmed to provide “helpful and harmless” answers.

Trump: “A wake-up call”

DeepSeek’s success has led to widespread reactions from both businesses and governments. Donald Trump called the launch a “wake-up call” for US companies and said it is now crucial for the US to “compete to win” in AI development. Australia’s science minister, Ed Husic, expressed concerns about DeepSek’s handling of data and security.

In China, the language model is being hailed as proof of the country’s technological progress and independence from Western technology. President Xi Jinping has previously emphasized AI as a national priority, and its success is seen as a step towards establishing China as a global leader in artificial intelligence.

The AI model has also faced technological challenges. On the day of its major breakthrough, the platform was attacked, according to the company, by a “large-scale malicious attacks” that led to temporary outages and restrictions on registrations. Even at the time of writing, DeepSeek is suffering from server issues and disruptions.
