Abstract: A method for encrypting data communication in a group video call is provided. The method includes receiving a media stream from a device with a first participant in a video conference call, the media stream including multiple data packets, for each data packet: identifying a prefix, indicative of a packet start, a metadata, and a user data that includes an encoded data for playing the media stream, forming an encrypted payload with the encoded data for each of the data packets according to a user key associated with the first participant in the video conference call, forming a source data packet consisting of one or more data packets, and generating a participant feed for the video conference call using a sequence of source data packets. A system, a memory storing instructions, and a processor for executing the instructions to cause the system to perform the above method, are also provided.
