As a result of increasing digitization and globalization, virtual product development increasingly involves collaborative work on complex problems. In the process, it can quickly become unclear which people are involved in the project and where certain data sets come from. As a consequence, data is often worked with, of which neither the origin nor the confidentiality of the origin is known.
The goal of this work is to design a methodology that makes it possible to trace the origin of a data set in order to determine both the origin of the data source and its confidentiality. Based on this, the developed methodology will be tested by means of a simple application example.
