Zoom meetings are TLS encrypted (like https). This secures the conference against third parties like hackers. The campus license of the university Paderborn is provided by a company located in Germany (Connect4Video GmbH – C4V). TLS encryption can’t secure the conversations against access of zoom or C4V. Both parties assure they don’t access the conversations but this can’t be guaranteed.
Confidential conversations can be held by using the end-to-end-encryption (E2EE). With this option, neither zoom nor C4V can access the content of the video conference. While using the end-to-end-encryption, not all zoom features are available. For end-to-end encrypted meetings, the Zoom client must be used. Joining the conference via browser is not possible.
Additional to the content of the conversations, zoom is gathering metadata. Examples are the IP address of the participants, device and hardware information, browser configuration, name and description of the meeting, date, time, duration of the meeting and number of participants. These information are available for zoom and C4V, even when the end-to-end-encryption is used. This information can be transferred to zoom USA for problem diagnosis and enhanced user experience. In case of privacy, gathering metadata must be seen critical. We recommend an evaluation if another service like BBB, Jitsi Meet, or DFNconf can be used which provides more privacy.
We recommend the usage of zoom only for conferences with significantly more than 20 participants. For smaller groups, services with more privacy should be used, like mentioned above. For conferences in which personal data is discussed, Jitsi Meet, BBB and DFNconf should be favored.
For conferences with confidential information like job interviews, appraisal interviews, appeal hearings, senate and chair conferences Zoom can only be used after a consideration of data protection laws by the host and only with activated end-to-end encryption.
For courses, lectures, seminars, conventions and public events, zoom normally can be used in default settings.
