Tracking pixels of collecting society WORT (VG WORT)

We use the so-called "tracking pixels" of collecting society VG WORT in the form of the SZM ("Scalable Central Measurement System") of the provider INFOnline GmbH (INFOnline GmbH, Forum Bonn Nord, Brühler Str. 9, 53119 Bonn) for the purposes of establishing key statistical figures related to the likelihood of texts being copied. The data obtained through this is collected anonymously. The detection function for the access figures uses either a session cookie or a signature which is created from different pieces of information transmitted automatically from your browser for the purposes of recognising
