摘要

Method has the following steps: input of data, containing at least a data packet, that contains data that conforms to at least a first data criterion into a first virtual data space; transfer of at least a second data packet to at least a second virtual data space; structuring of data packets according to predetermined types; calculation and generation of a type specific comparison data packet using the data packets and reference data packets and; transfer of the comparison data packet to a virtual data space and output of a comparison data packet. The invention also relates to a corresponding data medium and data processing device for method implementation.
