Many users are currently switching to signal or telegram messenger services. A tip for privacy advocates is ready for users.
Telegram and signal are considered more secure when it comes to data protection. However, these messenger services have multiple access rights on the smartphone.
Data protection on signal, telegram and whatsapp
WhatsApp is owned by Facebook, the parent company known as Data Octopus. “If you don’t have to pay for a product, you are the product,” says the Netflix documentary “The Social Dilemma”. Earlier this year, WhatsApp news service announced that it would share data with Facebook in the future. Data protection activists have asked Facebook’s Irish Data Protection Authority, which is responsible for Facebook’s in Europe, to test this approach immediately.
“As part of the Facebook company, WhatsApp receives information from other Facebook companies and shares information with other Facebook companies.”
According to the portal, WhatsApp knows Business Insider The app has a lot to say about its users whether they are using it or not. All you have to do is use the app for friends, acquaintances or colleagues.
Telegram and signal instead of WhatsApp
Telegram is considered to be the best alternative to WhatsApp. But privacy advocates are not enthusiastic. This is because the messenger service stores copies of chats on its servers. End-to-end encryption only applies to so-called secret chats, which are not set by default. The source code is only partially visible.
Users need to trust the company when it promises to encrypt chats on servers. Data protectionists also criticize the opaque company network behind Telegram.
Unlike WhatsApp, Signal is a non-profit foundation that is not interested in user data on its own. Signal message histories exist on the phone, not on the company’s servers. The company is very transparent and provides its source code on the GitHub platform. The messages are end-to-end encrypted so the company itself cannot see them. This is called the Zero Knowledge Principle. Many privacy experts recommend the intelligence service, including Whistleblower and privacy activist Edward Snowden.
Signal and telegram request this data
To run applications, Signal and Telegram request some data and access approvals.
According to the “Inside Digital” portal, Telegram is gaining the following approvals for access to smartphones:
- Telegram can record sound through the microphones of a smartphone. Technically, it works at any time, even when users are not currently using the app.
- Telegram can use the smartphone’s camera without user confirmation
- Between phone calls, the telegram can read the phone numbers of the callers.
- Messenger gains consent to dial phone numbers without user intervention – which could theoretically lead to costs.
- Telegram can read, change or delete data from shared memory.
- The telegram always knows the position of the person.
According to the Inside Digital Report, the signal has the following permissions:
- The signal can use the smartphone’s camera and take pictures and videos at any time without the user’s consent.
- Signal can add or change calendar meetings or send emails without the user’s consent.
- Messenger can read, send and delete SMS.
- The signal can record sound through the smartphone’s microphones even when the app is not in use.
- The signal knows when and with whom users are calling, and can dial phone numbers without the user’s consent – this can lead to unpredictable costs.
- Messenger is able to view and save all calendar appointments.
By default there is an option to deny access to the camera messaging services. This means that apps need to be asked every time they want to use the camera function. This ensures that users know how to use it. In general, users should be aware of their data not only on messenger services, but also on social media, because: “The Internet will never be forgotten.”
