Many times the video calls we make are of enormous importance and we even share important documents within the conversation itself. Well, to be protected, it is best to use technologies such as P2P and WebRTC that allow us to be much more secure.
P2P and WebRTC
The technology P2P (peer-to-peer) It consists of a system where transmission is not made through a central server, but rather each of the components of the conversation serves as a server to the other, so it prevents it from being accessed from outside, which makes the system much more secure. As all users in the conversation act like clients and servers From all the others, the system becomes much more closed, so sharing any type of files is also much more secure.
The technology WebRTC (Web Real Time Communications) is similar to what we have seen with P2P, but oriented towards web browsers. That is, it is a communication system between peers and in real time, for the exchange of all kinds of multimedia in browsers, which allows that there is no any kind of program in the middle. Current browsers are all compatible with this system so we can use whatever we want.
These two systems can be complementary, since in a P2P conversation, encryption may be a matter of WebRTC.
Video call tools
There are many applications, some well known, that use these systems. We are going to show you some of the most significant.
This is a chat where we can create rooms to communicate with whoever we want or to hold a meeting. Once we have created the room, we only have the link by email or the means that you want to those who will be the participants. The chat that we do, both written and by video, will be encrypted by the P2P system, so security is guaranteed, since a unique encryption has been generated, so the links to the rooms are fully protected.
P2P.Chat It allows us to invite the people we want, without any type of limit, except our own connection capacity. All video, audio and data are sent through a encrypted connection end-to-end through WebRTC.
Jami it’s a free software and open source with many interesting things, despite not being well known. It is very safe and has functions such as being able to make 4K video calls, recording system, being able to share the screen, voice calls or share files, among many other things. His communication system is P2P, so security and privacy are fully guaranteed, since it does not depend on any type of server for conversations. In addition, it also uses the TLS security Y distributed hash tables (DHT), storing the keys within the device itself. It is compatible with Windows, macOS, Linux, iOS and Android.
Tox is another of the tools used by the P2P system to protect video calls and chats. Everything that is done in Tox is encrypted, so the only people who will see our conversations are the ones we are talking to. This is aApplication is free and open source, which allows us to chat instantly with others, have voice calls fully encrypted so that only the participants can hear and even video calls that are just as secure. We can also share files or screen with others and create groups so that you can create group chats where several can use it at the same time.
Google Meet is the communication and meeting service of the great G. Meet uses the WebRTC system for many of its encryption features to provide the maximum privacy and security to his clients. It is a tool in which we can choose the free version, which is limited in some aspects, such as that if 3 or more people meet, they will only be able to see each other for one hour. But we also have at our disposal much more complete versions where they are going to charge us from 8 dollars a month to get extra functions and fewer limitations in what is the operation of the program.
Jitsi Meet is an open source application based on Simulcast architecture. It is a tool that bases your lectures on the browser using the WebRTC technology to achieve effective encryption and the highest privacy for the people who make up that conference. It is an application that will allow us to invite other people to the meeting that we have created, with an end-to-end encryption system at all times, with access limited to 100 people per meeting with options as interesting as that of share screen wave of remotely control the desktop of other participants, a faculty that can make a difference with respect to other similar tools.
BigBlueButton is a free tool that is specially dedicated to teachers that you want to carry out their work by video calls and that they look for the greatest possible security in them. Meetings will be a maximum of 100 participants with characteristics that are specially designed to teach at a distance, since we can have a interactive board, exchange of all kinds of content, rooms where you can rest and even the odd survey. The interface is extremely simple so that it is valid for all types of users and privacy is fully guaranteed. It is definitely the ideal solution for many teachers to be able to teach peacefully knowing that their safety and that of their students is fully assured.
