Peer to Peer WebRTC encrypted video chat conferencing

Encrypted WebRTC video conferencing app built on Javascript. Uses peer-to-peer connections for A/V and a centeralized sockets.IO signaling microservice server for command delegation. Bypasses firewalls and is obfuscation routing network safe (TOR).

Challenge and Approach

Our approach for satisfying this challenge for the AT&T Mobile App Hackathon​ in 2015 was to:

• Utilize Javascript and P2P web conferencing with an encrypted network layer.
• Video and audio conferencing utilizes Google's VP8 WebP compression and Opus Audio Codec.
• Signaling (muting audio and disabling webcam) and chat uses JSON over communicated over HTTPS websockets

Technologies, APIs, and Datasets Utilized

We made use of:

• [JavaScript] - WebRTC, Sockets.IO, JSON communication key encryption over AES

Microservice REST API explained

sockets.io listens to the following service REST endpoints:

1. /create - Join the conference room and assigns a room UUID
2. /message - P2P message routing and broadcast to all clients connected to the specific room UUID
3. /connection - signal connection setting for a specific UUID
4. /connection/shareScreen - notify the party leader that a request to share the screen is initated
5. /connection/unshareScreen - notify the party leader that a request to unshare the screen is initated
6. /join - Party joins a room as specified from client after the GET param
7. /disconnect - Disconnect the client from a room shut off all connections to the peer
8. /leave - Leaves the conference room

How to run

1. You first need to have node.JS installed
2. Next run npm install to download the appropriate Javascript dependencies
3. Run the server by: node server.js
4. You will have a URL generated for example: https://localhost:50000/

Go to https://localhost:50000 and you will have an instant P2P encrypted video conferencing app

Your peers will connect via an unique room key generated from the url: https://localhost:50000/?4wuluugvjhhaudgtrzhcnxw29

Once they join, you can have muti-party conferencing. Currently up to 4 people are only supported. Chat interface does not poll since no stateful logging is done client side.
