Abstract
A method for anonymizing movement data of road users equipped with a position detection device involves collecting movement data in the form of individual time- and position-related data records and transmitting the collected movement data to a backend server. At least some data records are transmitted indirectly via at least one other vehicle, or the position or time reference in at least some data records is made noisy prior to the transmission.

A method for anonymizing movement data of vehicles, the method comprising:
- collecting, by the vehicles, individual time- and position-related data records, wherein individual time- and position-related data records are movement data of the vehicles;
- and
- transmitting, by the vehicles to a backend server, the collected data records,
- wherein the vehicles are equipped with a position detection device and a communication device configured to transmit and receive data to/from the backend server and to/from other road users,
- wherein at least some of the collected data records are transmitted indirectly to the backend server via at least one other of the vehicles or a position or time reference in at least some of the collected data records is made noisy prior to the transmission to the backend server, and
- wherein all vehicles of a vehicle fleet connected to the backend server have a common shared vehicle certificate, wherein a signature created from the common shared certificate is transmitted by the vehicles to the backend server together with the collected data record directly or indirectly via at least one other vehicle.
