One of the most concerning aspects for the majority of Internet users at present is their privacy. It doesn't matter what devices we use, we're all in danger and our network activities and communications can be intercepted by third parties. Not that we have anything to hide but it's still a violation of our fundamental rights as individuals.
With the increase of cases featuring spy agencies and private companies, several projects have taken way to make our online communications much safer and more private. One of them is this Signal Private Messenger, the messaging and chat app supported by Edward Snowden that intends to become an alternative to WhatsApp.
Chats with end-to-end encryption
At the end of the day, there aren't too many differences between Signal and WhatsApp, Telegram, LINE or any other app. In other words, they can all be used to chat without our contacts individually or in groups. The main difference is that it incorporated end-to-end encryption before the rest of them and that it also incorporates functions from RedPhone and TextSecure, two apps developed by Open Whisper Systems that come along with state-of-the-art technology in the field of secure and private communications.
The opinions of thousands of users about Signal make it a very interesting app.
Signal guarantees that the intermediate server between the sender and the receiver can never access the communications and, therefore, never store data. Furthermore, it also offers us all these features:
- Possibility to communicate by means of individual and group chats. These group conversations are also encrypted and the server cannot access metadata such as group members, names or icons.
- End-to-end encrypted communications.
- Send messages, photos, audio files and videos in a safe manner.
- Built-in phone calls by means of the VoIP protocol.
- Doesn't require registries, your phone number is your identifier.
This is the version in APK format for Android smartphones but there's a version for Windows by means of a Google Chrome extension that allows you to use it on your PC desktop.
