What it is, how it works, and its tools

Many times our video calls are of great interest and even we are sharing important documents within the conversation itself. Well, to be protected, it is better to use technologies like P2P and WebRTC which allow us to be more secure.

P2P and WebRTC

Technology P2P (peer-to-peer) It consists of a system in which transmission is not done through a central server, but rather through every component of the conversation Serving as a servant of the other, So it blocks access from outside, making the system more secure. All users in the conversation behave like Clients and servers Among others, the system gets more locked down so sharing any kind of files is also more secure.

Technology WebRTC (Real-Time Web Communications) It’s similar to what we’ve seen with P2P, but it’s geared towards it Internet browsers. That is, it is a peer-to-peer and real-time communication system, for the exchange of all types of multimedia in browsers, which allows non-existence What kind of program in the middle. All current browsers are compatible with this system so we can use whatever we want.

These two systems can be complementary, because in a P2P conversation, the encryption might be a WebRTC issue.

Video call tools

There are many applications, some of which are well known, that use these systems. We will show you some of the most important ones.
