Technische Universität Braunschweig takes data protection very seriously and treats your personal data confidentially and in accordance with the statutory provisions.

1 Scope of personal data processing

A registration (login) with personal data is only required for the submission of publications by university members, not for the search for or the read access to publications. To publish, university members log in with their TU identifier. Authorization is provided through the IDP (Identity Provider - DFN-AAI Shibboleth) of Technische Universität Braunschweig. The repository processes and stores the following user data:

  • Name
  • User ID
  • E-Mail-Address
  • Time and date of last login
  • User roles (employee, student)
  • Link to the publications released in this repository, incl. date and time of the last modification The storage and processing of this data is done for the performance of the task assigned to us of supporting teaching and research according to Art. 6 para. 1 lit. e GDPR in conjunction with § 3 NDSG and is required
  • to prove the authorization for publication in our repository
  • for communication with authors in the context of the publication process
  • to prove authorship of e-publications

2 Publication data

The aim of this repository is the worldwide publication and provision of electronic publications (e-publications and e-dissertations) in the sense of Open Access. For this purpose, we also store, process and publish personal data of the persons involved in publications:

  • Names und Roles (e.g. author, editor)
  • Unique author identifiers (e.g. ORCiD, GND)
  • Information on organizational affiliation (e.g. university, faculty, institute)

This serves to provide unambiguous confirmation and acknowledgement of authorship, citability, and better findability of the publications. With the release of the publication, we also transfer this personal data to third parties and make it available via interfaces to:

  • the German National Library within the scope of the reporting obligations for the purpose of archiving and proof in the German National Bibliography
  • the registration agency DataCite for the unique assignment of permanent publication identifiers (DOI)
  • scientific and general search engines like Google, Google Scholar, BASE
  • third parties worldwide, via interfaces such as OAI (Open Archives Initiative) and the Google Sitemap protocol

Publication and thus distribution and worldwide accessibility will only take place with the consent of the authors or editors and only after signing the publication contract.

The storage in log files is done to ensure the functionality of the website.

The use of cookies increases the user-friendliness and security of this platform. Usage data is only collected and stored in anonymized form for optimization purposes.

For the optimization of our offers, personal data do not provide any added value.
