The weekly c’t podcast c’t uplink is available …

This uplink sequence about messenger security is also explicitly aimed at non-nerds – at least in the first 20 For a few minutes, we try not to stir too much in technical details; you can also send the link to this uplink to your in-laws.

Among others, Eva-Maria Weiß, Sylvester Tremmel, Jürgen Schmidt and Jan-Keno Janssen clarify the following questions: What about WhatsApp – GTC change on yourself? How do Signal and Telegram differ? Who is behind the messengers? Why are there so big differences in speed and functionality (animated stickers!)? Why does something like cross-messenger communication not catch on?

Which messengers are GDPR compliant? What about Threema, Wire and Matrix? Which is safer, Threema or Signal? How does end-to-end encryption work? What about the metadata on WhatsApp? Why is Signal often unreliable? What is to be made of Telegram’s promise that the data are in different data centers in different jurisdictions and therefore hackers and employees cannot access the data?

We also talk about Messenger politics: How US-centric is Signal? Is Telegram in danger of being thrown out of the app stores because of radical chat groups? Why did Telegram recently start deleting groups? What does WhatsApp know about me?

Also there: Jan-Keno Janssen, Jürgen Schmidt, Sylvester Tremmel and Eva-Maria Weiß .
