Viber follows WhatsApp with end-to-end encryption

Published

on

Viber has followed in WhatsApp’s steps with the announcement of end-to-end encryption across all major devices. These include Android and iPhone, iPad, Android tablets, PC and Mac desktops. 

This feature will be available over the coming soon to all users who have the latest version of Viber. It includes strengthened security in every voice or video call, message, video and photo, in both group messages and one-to-one communication. As part of this update, Viber also launches ‘Hidden Chats’ allowing users to hide specific chats from the main screen so no-one but the user knows they exist. These chats can only be accessed using a four digit PIN, providing an optional additional layer of privacy to users’ personal communications.

We take our users’ security and privacy very seriously, and it’s critical to us that they feel confident and protected when using Viber,” said Michael Shmilov, COO of Viber. “Because of this, we have spent a long time working on this latest update to ensure that our users have the most sophisticated security available and maximum control over their communications. We will continue to make this an ongoing priority as digital communication evolves.

Full End-to-end encryption

Rolling out globally over the coming weeks, users will automatically be protected by end-to-end encryption in all communications on their smartphone once they have upgraded to the latest version of Viber – v6.0 or higher. Users who are also using Viber on an iPad, Android tablet or desktop will be prompted to re-connect it to their phone using a QR code.

All communications can benefit from an additional layer of security through account verification. Users will see a color-coded lock on the right hand side of the screen indicating the level of security:

  • Grey Lock: During an end-to-end encrypted conversation and call users will see a grey padlock icon. Tapping on this icon will display a tooltip letting users know that messages sent by the participants are encrypted.
  • Green Lock: Users also have the option of manually authenticating their contacts by selecting that they are ‘trusted’. This means that the selected contact’s authentication key will be monitored for future changes so users can be certain that they’re talking to the right person at all times. Tapping on the green padlock will display a tooltip letting users know that messages sent by the participants are encrypted and your contact is verified.
  • Red Lock: If there is a problem with the authentication key of a previously trusted user, the padlock will turn red. The breach may simply mean that a user has changed their primary phone; however, it can also indicate a man-in-the-middle-attack. To solve a possible breach state, the participant needs to be re-trusted. Tapping on the red icon will display a tooltip noting that Viber cannot verify this number.

Hidden Chats

Users will now also be able to hide specific one-on-one or group conversations from the ‘chats’ screen so that no-one knows they exist and access them using a four digit PIN. Users can hide the conversation by tapping on the info screen for a particular chat. It will then ask for a four digit PIN or, for iOS users, provide an option for a fingerprint. Users will be notified of a message in a Hidden conversation without the text of the message, or who it is from, appearing on the screen.

This is not bi-directional, meaning if one user hides the conversation, nothing will be changed on the recipient’s side.

This latest update, along with the ‘Delete’ feature – which allows users to delete messages on the recipient’s phone even after they’ve sent them whether the person has seen it or not – demonstrates Viber’s increased focus on putting its users in control of their privacy and personal communications.

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entries via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.
