Abstract:
1. A method for transmitting useful data from a data source to a data sink, comprising: connecting the data source to a locating unit; at the data source, linking supplementary data to the useful data, the supplementary data derived from information from the locating unit and including one of an item of time information describing a time value at the data source when the useful data is transmitted by the data source or an item of location information describing a location of the data source when the useful data is transmitted by the data source; at the data source, transmitting the supplementary data to the data sink contemporaneously with the useful data; at the data sink, linking additional supplementary data to the useful data after receiving the useful data at the data sink, the additional supplementary data being derived from additional information of a second locating unit connected to the data sink and including one of an item of time information describing a time value at the data sink when the useful data is received at the data sink or an item of location information describing a location of the data sink when the useful data is received at the data sink; at a checking device, receiving the useful data, the supplementary data, and the additional supplementary data from the data sink; and at the checking device, processing the supplementary data and the additional supplementary data to reconstruct a transmission path that sequentially describes the transmission of the useful data from the data source to the data sink; wherein the useful data includes non-location and non-time information that is processed at the data sink.
