Skype for Business: Data Protection Information

Skype for Business (S4B) is used for video and telephone conferences. Log files are created while the software is used and these are analyzed by authorized personnel in order to monitor the quality of service and in the event of a security incident. The log files contain information on when content has been accessed, which S4B client was used, how much data was transferred at this point, and whether access was successful. As a rule, this data will not be passed on to third parties except when required by law or for the prosecution of a criminal offense.

3. Security

3.1. Location of storage and data transmission

The data is saved to servers in data centers on the JGU campus, which are located at several sites with high availability and a fail-safe design. Access is only possible for authorized persons, who are employees of JGU’s Data Center.

All transmissions (including audio and video) between S4B clients and JGU servers take place over encrypted connections.

3.2 Recording Conferences

Only clients of the organizers or participants can record conferences. All participants will be notified by the client if someone begins a recording.

Recordings are stored unencrypted on the terminal device of the person responsible for making them. They are only saved to JGU servers indirectly if the responsible person transfers them to the servers.

The data is needed to carry out video and telephone calls. The legality for this is based on the performance of tasks carried out in the public interest according to Art. 6 para. 1 lit. e) GDPR in conjunction with Section 2 of the HochSchG.
