Note on the security and protection of your data:

All talks at the Big Cyber Ideas Festival are encrypted and are hosted on the ETH network. To guarantee this, we use an ETH-specific Zoom variant, “ETH Zoom on Premises”, in which the infrastructure of ETH Zurich is used as a data center for all audio, video, and chat data. This encrypted data is not uploaded to the Zoom cloud. The hosts of our events and meetings create the “ETH Zoom on Premises”-connection, participation is possible without a special account. Only meeting metadata data, such as the meeting ID and the time of the meeting, are transmitted to the Zoom Cloud via a secure connection.
