Abstract: A method for combining different partial data includes providing a secure connection between a connection unit in a first network and an analysis unit a second network, separating original data into at least two items of partial data comprised of analysis data and personal data as first and second partial data that can be assigned to each other by way of assigning information, pseudonymizing the second partial data, transmitting the first partial data and pseudonymized second partial data and the assigning information to the analysis unit, storing the second partial data on the connection unit, providing third partial data on the analysis unit in the form of analyzed first partial data, transmitting the third partial data and the pseudonymized second partial data with the assigning information to the connection unit via the secure connection, and combining the third partial data and the second partial data using the assigning information.
