Elon Musk wants to use Signal instead of Facebook – that’s why and how it works

Technical tycoon Elon Musk – known as the widely known washing cars in solar orbit as it is for intercession against COVID-19 safety measures – opened on Twitter last week to list Facebook on its latest privacy policy updates for its supposedly secure WhatsApp encrypted messaging app. Musk instead, recommended users select the Signal encrypted messaging application.

The tweet was then retouched by Twitter CEO Jack Dorsey. Shortly afterwards, Signal wrote on Twitter that it was working to deal with the wave of new users.

Musk’s support on Twitter also accidentally led to a rise in shares in the biotech company Signal Advance, despite the fact that it is completely unrelated to Signal, which is not a publicly traded company.

This is not the first time Musk has publicly argued with Facebook over privacy concerns. In 2018, he not only removed his own Facebook page, but also those of his companies Tesla and SpaceX. However, his opinion on the long-standing battle between Signal and WhatsApp is not out of base.

Both encrypted messaging applications are found to have security errors during the years that have been resolved. For years WhatsApp openly collects certain user data to share with the parent company Facebook. His latest policy change simply expands on that. Signal, on the other hand, has history of battles any person who wants your data, and adds features for further anonymization you where possible.

Here are the basics of Signal that you need to know if you are interested in using the secure messaging app.

What Signal is and how encrypted messages work

Signal is a typical one-touch installation application that can be found in your usual markets such as the Google Play Store and Apple’s App Store, and works just like the usual text messaging application. This is an open source development provided free of charge by the Signal Non-Profit Foundation and has been used for years by well-known privacy icons such as Edward Snowden.

The main function of Signal is that it can send text, video, audio and picture messages, protected from end-to-end encryption, after confirming your phone number and allowing you to independently verify the identity of other Signal users. You can also use it for voice and video calls, one-on-one or with a group. For more immersion in the potential pitfalls and limitations of encrypted messaging applications, CNET Laura Hautala’s explanation is the savior of life. But for our purposes, the key to Signal is encryption.

Despite the noise around the deadline, end-to-end encryption is simple: Unlike normal SMS messaging apps, it distorts your messages before sending them, and removes them only for the verified recipient. This prevents law enforcement, your mobile operator and other eavesdroppers from being able to read the content of your messages, even when they intercept them (which happens). more often than you think).

In terms of confidentiality, it is difficult to surpass Signal’s proposal. It does not store your user data. And in addition to its encryption capability, it provides you with advanced on-screen privacy options, including app-specific locks, blank pop-up notification windows, anti-surveillance blurrs, and missing messages. Random errors have proven that this is the technology away from the bullet, of course, but Signal’s overall reputation and results have kept it at the top of the list of privacy tools for anyone who knows about privacy.

For years, the main challenge to Signal’s privacy was not in its technology, but in its wider perception. Sending an encrypted Signal message is great, but if the recipient doesn’t use Signal, your privacy may be zero. Think of this as the herd immunity created by vaccines, but the confidentiality of your messages.

Now that Musk and Dorsey’s approvals have sent a surge of consumers to increase privacy, that challenge may be a thing of the past.
