BigBlueButton is one of the most popular open-source software solutions for taking online classes and a good alternative to Zoom with respect to privacy.
BigBlueButton encrypts all content that is sent between your browser and the website server.
BigBlueButton always tries to reduce the maximum data that could be stored in the server as well as limit the data that by default are exposed with public links and accessible to anyone.
BigBlueButton uses multiple layers of security like
- BigBlueButton Includes HTTPS for securing connections between users’ browsers and the server,
- BigBlueButton uses a checksum to validate API calls,
- BigBlueButton uses Datagram Transport Layer Security (see DTLS) to ensure audio and video data packets are sent via WebRTC over UDP connections.
