Challenge

Secured messaging application with chat and group voice calls

Our client needed an end-to-end encrypted messaging app that features not only text messages but file sharing, voice messages, including group calls. The solution should support blocking some preinstalled apps like Browser and others.

The app should have an Android enterprise solution that allows sending users over the air package, which will take over their phone and install the correct software.

Solution

We installed VMware Workspace ONE, an intelligence-driven digital workspace platform that supports blocking some preinstalled apps like Browser and others, and distributes a new version of the App.

We changed the Android WebRTC solution to support end-to-end encryption for audio call functionality. 

Besides this, we developed a high-level security Android application and a well scalable backend solution to ensure secure and reliable communication between users.

Features

• User can send end-to-end encrypted text/image messages

• User verification

• Peer-to-peer end-to-end encrypted group call

• End-to-end encrypted group chat

• Voice message

• Secret chat(anonymous use chat)

• Specific settings on the user account(personal and for other contacts)

• End-to-end encrypted media files exchange

• End-to-end encrypted push notifications

Results

• The end-to-end encrypted messaging application also includes group call

• High-security solution with the possibility to set up message disappearing timer

• Implemented Workspace ONE that allows deleting the various pre-installed applications and the application distribution

• Support the user verification process
