Data communication engineers are on high alert after Whatsapp enabled something that only apps like Telegram, Signal, and other apps had; end-to-end encryption of messages. You might have seen it enabled on all of your chats - activating it on their platform. There are a billion people using Whatsapp in the world so it is quite the stance for privacy in the world of today. The sudden stance comes on the back of the revelations that the FBI were able to unlock the iPhone of the San Bernadino shooter that Apple refused to unlock. 

Whatsapp (owned by Facebook) spoke about the move to encryption, saying, "When you send a message, the only person who can read it is the person or group chat that you send that message to. No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us." 

IBTimes, however, published a list of apps that people could further look into, to ensure that their privacy in data communications is secure. Something that a lot of people want with recent scandals like the Apple case, the Panama Papers et al:

Their list named the following apps that could be installed for extra privacy with data communications: 

Signal: Publicly endorsed by former NSA spy Edward Snowden 

iMessage and Facetime
