Data protection in live online communication, e.g. in web conferencing and virtual classrooms, is particularly important because personal data is collected that should only be used for the purpose of online communication and not for e.g. advertising purposes. In addition, it is necessary to ensure that there is no covert tracking of performance and that live webcam transmissions may not be recorded and published without the consent of the persons concerned. It is crucial that the provider of the web conferencing software used ensures the permanent protection of both personal and sensitive business data in the context of live online communication.
