If you don’t believe WhatsApp / Facebook, you are welcome to read the statement of the State Data Protection Commissioner of Saarland (Germany): All experts agree (for once) that this technology is the most secure encryption method today. WhatsApp, Threema and Signal use end-to-end encryption, which means that the data to be transmitted is encrypted on the sender’s side and only decrypted again on the recipient’s side.
“Weak encryption, on the other hand, enables attackers to reduce this time period so drastically that the attack becomes viable,” explains Frieder Steinmetz, who researches messenger security at the Technical University Hamburg.Ĥ) Telegram, Signal, WhatsApp, Threema – Which messaging app has the most secure encryption? “Encryption” describes many possibilities, which differ significantly in quality: How much effort do attackers have to expend to gain access to the chats?įiguratively speaking: Strong encryption means that an attack requires a computational effort of several billion years. But is this true? That essentially depends on the quality of the encryption of a messenger service. 💡 Tip: If you want to learn more about data privacy and WhatsApp, I recommend our editorial WhatsApp and data privacy in customer communication – Everything you need to know!ģ) Can messaging apps like WhatsApp read my chats?Ī second point that is repeatedly criticized is the assumption that chats between private individuals – just like those between companies and customers – can be “read” by the messaging app operator, the authority and / or a hacker. Private use of messaging apps is in no way affected by the scope of the GDPR – the GDPR only applies to legal entities. How companies can communicate via messaging apps in compliance with the GDPR (requirements include: Information and declaration of consent of the user, clean opt-in and opt-out).Īnother common misunderstanding is that the private use of messaging apps is in the scope of GDPR. Carsten Ulbricht (“Rechtzweinull”), who specializes in IT and social media law, assured me, all messaging apps from WhatsApp to Threema are now GDPR-compliant. All messaging apps deal with this issue differently. This essentially regulates the handling of data – in other words, what data a company is allowed to process from its customers/users, etc., and to what extent. Of these, only a few have fundamentally dealt with the European General Data Protection Regulation (GDPR). Many people throw “data protection” and “security” – two completely different topics – into the same pot of the rumor mill.
The messaging tool cannot be installed by MEPs and staff “without being tested and approved by the security service and the standard configuration team,” according to the EU Parliament’s IT support.Ģ) Security is more than just data protection Incidentally, anyone who read the article and the justification more closely quickly understood that the parliament’s directorate did not reject Signal because of security shortcomings, but because Signal is “not a standard software” in the European Parliament. Signal – was quickly discussed in insider circles. The security of messaging apps – especially WhatsApp vs. “EU Parliament prohibits the installation of the messaging app Signal by Members of the European Parliament (MEP) “: This headline at caused quite a stir.
