Abstract

A method for transmitting useful data from a data source to a data sink, the data source being connected to a locating unit, the useful data in the data source being assigned supplementary data derived from information of the locating unit connected to the data source, which are transmitted to the data sink together with the useful data, wherein the received useful data in the data sink are assigned additional supplementary data, which are derived from additional information of a locating unit connected to the data sink. A system for transmitting useful data from a data source to a data sink, the data source being connected to a locating unit and the data source being designed to assign to the useful data supplementary data derived from information of the locating unit connected to the data source and to transmit it to the data sink together with the useful data, wherein the data sink is connected to a locating unit and the data sink is designed to assign to the received useful data additional supplementary data, which are derived from additional information of the locating unit connected to the data sink. When the supplementary data assigned on the source-side and the additional supplementary data assigned on the sink-side are set in relation to each other, information about the data transmission may be obtained therefrom.

Claims

1. A method for transmitting useful data from a data source to a data sink, comprising:

connecting the data source to a locating unit;

assigning the useful data in the data source supplementary data derived from information from the locating unit;

transmitting the supplementary data to the data sink together with the useful data; and

assigning the useful data received at the data sink additional supplementary data, the additional supplementary data being derived from additional information of a second locating unit connected to the data sink.

2. The method as recited in claim 1, further comprising:

setting the supplementary data and the additional supplementary data in relation to each other.

3. A system for transmitting useful data from a data source to a data sink, comprising:

a first locating unit connected to the data source, the data source assigning to the useful data supplementary data derived from information from the first locating unit and transmitting the supplementary data to the data sink together with the useful data; and

a second locating unit connected to the data sink, the data sink assigning to the useful data received at the data sink additional supplementary data, wherein the additional supplementary data is derived from additional information of the second locating unit.

4. The system as recited in claim 3, further comprising:

a device for setting the supplementary data and the additional supplementary data in relation to each other.

5. The system as recited in claim 3, wherein the supplementary data and the additional supplementary data include an item of time information of the first locating unit and the second locating unit.

6. The system as recited in claim 3, wherein the supplementary data and the additional supplementary data include an item of location information of the first locating unit and the second locating unit.

7. The system as recited in claim 5, wherein:

a relation corresponds to a time comparison of the supplementary data and the additional supplementary data, and

a run time of the useful information from the data source to the data sink is determined thereby.

8. The system as recited in claim 7, wherein:

a relation corresponds to a location comparison of the supplementary data and the additional supplementary data, and

one of a distance and a run path between the data source and the data sink is determined thereby.

9. The system as recited in claim 8, further comprising:

linking the useful information in each forwarding processing unit with supplementary information generated in a locating unit assigned to the respective forwarding processing unit, on a path from the data source to the data sink via at least one forwarding processing unit, wherein the local path of the useful information is reconstructed by the relation.

10. The system as recited in claim 9, further comprising:

linking the useful information in each forwarding processing unit with supplementary information generated in a locating module assigned to the respective forwarding processing unit, on a path from the data source to the data sink via at least one forwarding processing unit, wherein the temporal processing sequence of the useful information is reconstructed by the relation.

11. The system as recited in claim 3, further comprising:

entering at least a portion of the useful information into the data source with the aid of a changeable memory corresponding to a chip card, which is analyzable by the data source.

12. The system as recited in claim 11, wherein the changeable memory is provided to store the supplementary data transmitted from the data source together with the useful data.

13. The system as recited in claim 12, wherein the changeable memory is a component of one of a personal computer, a mobile telephone, and a PDA.

14. The system as recited in claim 3, wherein at least one of the data source and the data sink corresponds to one of a mobile telephone, a personal computer, a laptop computer, a PDA computer, a driver-information system of a motor vehicle, and an automated teller machine.

15. The system as recited in claim 3, wherein the locating unit includes one of a satellite receiver corresponding to one of a GPS receiver and a GALILEO receiver, a mobile radio receiver corresponding to one of a GSM, GPRS, and UMTS mobile radio receiver, an inertial sensor system, a digital map, and a map-matching routine.

16. The system as recited in claim 3, wherein the useful data and supplementary data are linked to each other using encryption technology.
