Plagiarism Prevention Pool (PPP)

PlagScan’s core technology refers to a large index of all kinds of web sources and digital content. Aside from the internet as a source, PlagScan provides its Plagiarism Prevention Pool. The PPP is an exclusive joint archive that enables cross checking submissions with documents from others. The pool expands constantly because it adds all submissions from participating institutions and publishers.

Generally, documents from organizations can become part of the PPP. It is possible to mark single documents as private to exempt them from being added to the PPP or retract them afterward. Alternatively, organizations can entirely opt-out by choosing a private repository. Yet, we strongly recommend taking advantage of the PPP – one of PlagScan’s most valuable features.

Benefits of the PPP

  • The PPP is a complimentary service of PlagScan
  • A broader database with other institutions allows checking new submissions against older ones. This eliminates the possibility for students to plagiarize prior work from relatives or friends across cohorts.

  • The joint archive enables cross-checking with other institutions, organizations, and publishers on a global scale

  • PlagScan contributes a number of different external sources such as open journals and free of charge documents within the PPP

  • Documents and their owners remain anonymous, even if it was identified as a source of potential plagiarism at a different institution (see next paragraph)

The PPP complies with German data security and copyright laws

If the software finds a match within a document from another institution, sources are only shown as snippets of three successive words to ensure the privacy of the original owner and source. If an institution wishes to access the document's full-text, the owner of the matched source has to grant explicit permission.

If no permission is granted, the document won’t be accessible to the other institution.
