Functional description

BBB is a video conferencing system used at the University of Leipzig for teaching purposes (online lectures, seminars, tutorial groups) and study purposes (tutorials, online exchange between students) as well as for general official tasks (staff meetings, group meetings).

The main functions of BBB include:

  • Providing conference rooms including breakout rooms.
  • Transmission of sound, screen content, file content and video as part of a conference
  • Video recording
  • Creating and sharing notes during a videoconference
  • Textual messaging during a video conference
  • Displaying a whiteboard for collaborative content work

Participants in a videoconference are people who take part in a videoconference. They can activate their video camera, use chat and transmit voice. They can view the moderator's content.

Facilitators lead a videoconference and present content. They can activate their video camera and manage participants (e.g. mute, allow to conference, remove from a conference).
Special features for the purpose of teaching and study

BBB can be used for teaching and e-learning based on the stipulations of the examination regulations of the degree programmes.

Examinations may only be taken via this system with the student's consent. Recording of examinations is not permitted.

Recording of courses is only permitted if there are no participants in the room or if all participants and moderators have clearly and verifiably agreed to the recording beforehand. Secret recording of a video conference is a criminal offence.
General information on data processing

We collect and use personal data of our users only to the extent necessary to provide BBB and its functions.

By using BBB, you agree to the terms of use and data protection information in accordance with Art. 6 Para. 1 a DSGVO.

Data processed

BBB is characterised by its data economy. The following data is collected when using BBB:

  • Connection data (e.g. IP address, browser type, date and time of access).
  • Access data: User name, password in encrypted form
  • Content data (e.g. uploaded files, chat contributions, surveys).

Data processing takes place exclusively on servers of the University Computer Centre. Access data and content data are stored for the period from initial use until termination of the service offer. After termination of the service offer, the data will be deleted.

Unless otherwise stipulated by law, no data is transmitted to third parties in the legal sense.

The temporary storage of connection data, in particular the IP address, by the system is necessary to enable delivery of BBB to the user's computer. For this purpose, the user's IP address must remain stored for the duration of the session. The legal basis for the temporary storage of the data is Art. 6 para. 1 lit. f DSGVO.
Log files

The processed data (connection/access and types of content data) are stored in log files to ensure the functionality of BBB. In addition, we use the data to optimise BBB and to ensure the security of our information technology systems. These purposes are also our legitimate interest in data processing according to Art. 6 para. 1 lit. f DSGVO.

The data in the log files are deleted after a period of 14 days. Only administrators of the University Computer Centre have access to the log files.

The collection of data for the provision of BBB and the storage of the data in log files is absolutely necessary for its operation. Consequently, there is no possibility for the user to object.
