The Coronavirus Disease (COVID-19) Pandemic has promoted the increasing patronage of video conferencing solutions like Zoom globally as the only way organisations, Governmental agencies and individuals can continue to conduct meetings and other teleworking activities to control the spread of COVID-19. Zoom came under serious security scrutiny after reports of Zoombombing, confidentiality issues and the alleged routing zoom calls through the servers of China. Even though Zoom uses 256-bit TLS and AES-256 Encryption schemes, it failed to address the security concerns expressed by researchers and users. In an attempt to find solution to these security concerns, we have proposed a new system architecture that allows the user or an organisation to take responsibility of securing the video and audio files generated using the zoom conferencing solution.
