The Background
Security has been a burning issue in communication over the past few years. This is why our client tasked us with creating a robust system that will give users total control over the level of security of their communications.
2/7
The Challenge
Our technical teams had to implement several cryptography schemes depending on each use case. The true challenge was coming up with an approach that will have very high levels of security while maintaining performance and efficiency. Making three different systems (iOS, Android and the backend) talk to each other was no picknic either.
3/7
The Approach
We created separate encryption schemes for local data storage, realtime communications as well as password data exchange.
We developed our own realtime communication server with advanced message queueing, delivery monitoring and custom retry policies.
Finally to enable instant communication we’ve developed an in-house messaging platform. At this stage we have proceeded with a total redesign of the platform.
Our design team created a unique visual identity for the apps, and identity that emphasizes the platform's security first approach.

Logo Design
The logo had to be representative of the smart and highly secure communication nature of the platform.

The Technologies
The realtime communication server was built in house written in pure C for optimal performance. The backend was built using the performant phalcon php framework. For the mobile apps we used the latest encryption specification to ensure high levels of security and performance.
