Abstract

The disclosure relates to a method for processing data recorded by a motor vehicle. In a first step, at least one set of parameters for a temporal and spatial obfuscation of the recorded data is received. An item of data recorded by a motor vehicle is additionally received. A temporal and spatial obfuscation is then applied to the received item of data using the at least one received set of parameters. The obfuscated item of data is finally forwarded for further processing. The obfuscation may take place within the motor vehicle or in a back end connected to the motor vehicle.

First claim

What is claimed is:

1. A method for processing data recorded by a motor vehicle, comprising:
receiving two or more sets of temporal and spatial obfuscation parameters from a data user;
automatically receiving data recorded by a sensor of the motor vehicle;
automatically applying a temporal and spatial obfuscation to the received data using the two or more received sets of parameters, wherein the two or more sets of parameters are used such that a predefined proportion of the data is obfuscated with a large-scale temporal obfuscation in combination with a small-scale spatial obfuscation, whereas another portion of the data are obfuscated with a small-scale temporal obfuscation in combination with a large-scale spatial obfuscation; and
forwarding the obfuscated data to a data pool for an automatic driving function.

2. The method of claim 1 , wherein the two or more sets of parameters comprises specifications, defining a vehicle position or an area around a vehicle position to which the two or more sets of parameters are applied to.

3. The method of claim 1 , wherein the two or more sets of parameters comprises specifications as to which type of recorded data the two or more sets of parameters are applied to.

4. The method of claim 1 , wherein the selection between the two or more sets of parameters is made at random.

5. The method of claim 1 , wherein the predefined proportion is adapted depending on an application.

6. The method of claim 1 , wherein, as an alternative to receiving the two or more sets of parameters, a request to use a pre-existing set of parameters for the temporal and spatial obfuscation of the recorded data is received.

7. The method of claim 1 , wherein a first set of parameters that causes an obfuscation of the recorded data involving a small-scale temporal obfuscation in combination with a large-scale spatial obfuscation is transmitted, and in response to an event being identified in the obfuscated data, a second set of parameters that causes an obfuscation of the recorded data involving a large-scale temporal obfuscation in combination with a small-scale spatial obfuscation is transmitted.

8. A non-transitory storage medium with instructions which, when executed by a computer, prompt the computer to carry out the method of claim 1 .

9. The method of claim 1 , comprising training the automatic driving function using the data pool.

10. A device for processing data recorded by a motor vehicle, comprising:
an input for receiving two or more sets of temporal and spatial obfuscation parameters, wherein a selection is made between the two or more sets of parameters and for receiving data recorded by the motor vehicle from a data user;
an anonymization circuit for applying a temporal and spatial obfuscation to the received data using the two or more received sets of parameters, wherein the two or more sets of parameters are used such that a predefined proportion of the data is obfuscated with a large-scale temporal obfuscation in combination with a small-scale spatial obfuscation, whereas another portion of the data are obfuscated with a small-scale temporal obfuscation in combination with a large-scale spatial obfuscation; and
an output for forwarding the obfuscated data to a data pool for an automatic driving function.

11. The motor vehicle, comprising the device of claim 10 .

12. A back-end device for processing data recorded by the motor vehicle comprising the device of claim 10 .

13. The method of claim 2 , wherein the two or more sets of parameters comprises specifications as to which type of recorded data the two or more sets of parameters are applied to.

14. The motor vehicle, configured to carry out the method of claim 1 .

15. A back-end device for processing data recorded by the motor vehicle, configured to carry out the method of claim 1 .

16. The device of claim 10 , comprising an automatic driving system, configured to use the data pool for training the automatic driving function.
