Total Encryption: By default, Line secures all text messages and video/voice calls with end-to-end encryption with a feature called ‘Letter Sealing.’ Only the sender and recipients can view messages/calls. The app uses the ECDH protocol for encryption. ECDH is an anonymous key agreement protocol that allows two parties to establish a shared secret over an insecure channel.

It’s Social: Line also has a timeline feature, much like Facebook/Twitter, that allows users to post pictures, text, and stickers on their homepages. However, a few years back, under the political pressure of certain countries, Line had reportedly done keyword filtering and emoji censorship.

Best Voice & Video Calls: With WhatsApp, you can send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other media.

Fully Encrypted: All messages, voice/video calls on WhatsApp are completely encrypted. For this, it makes use of the Open Whisper Systems Signal Protocol, which is absolutely good. It ensures only you and the person you’re communicating with can see what is sent, and nobody in between, not even WhatsApp.

Secure: The optional two-step verification feature allows you to add more security to your account by setting a PIN that is required to verify your phone number on any device.

Doesn’t Store Your Data: Further, WhatsApp doesn’t store your messages on its servers. So, even Law enforcement agencies who turn up at its offices get access to nothing.

Problems: However, it is not advised to back up your WhatsApp messages to the cloud since that would deliver unencrypted copies of your message to the cloud provider. Previously, WhatsApp has had some security flaws, but there were all promptly fixed at the earliest. Recently, WhatsApp has started sharing user data with its parent company Facebook, and that has made us rank it last in our list.


Stay Safe!

Most of the time, it’s the shady apps/malware that results in the hack. Users unknowingly download such apps that easily gain access to the camera and mic. The app/malware gives away all the personal information to a hacker who then leaks it.
Remember! Always download apps from the official app store or trusted sources.

Other times, videos are directly recorded by the person you’re communicating with using a screen recorder app and leaked.
So please make sure the person you are video chatting with is 100% trustworthy.

With that said, the safe video calling apps mentioned in this article are best recommended for personal and private video chats with your close ones.
