Theses are about the comparative characteristics of well-known videoconferencing services. The fundamental vulnerability of such services, due to the peculiarities of network data transfer protocols, is noted. The comparison focuses on end-to-end encryption, two-factor authentication, and the ability to manage data on the client side and on the server. The comparison results are presented in a table. According to the analysis results, the most secure services are Cisco Webex Meetings and GoToMeeting.
Theses are about the files protecting that are transferred within the videoconference. Onion nesting and file encryption are suggested. According to algorithm, one of the layers contains a mechanism for comparison the real and expected IP-address. In case of a match, the inner protective layer is removed and the file becomes available. If there is a mismatch, the data will be destroyed. The algorithm will make it impossible to intercept attached files from a media stream that is weakly protected.
