Data is anonymously transmitted from a vehicle to a computer via a data link. The vehicle authenticates itself for the data transmission. The vehicle authenticates itself as a client in a token server by one or more authentication methods. The authentication and authorization of the client is checked by the token server. If the token server determines that the client is not blocked, a currently valid fleet token, which is identical for all clients within a pre-determined period of time, is sent by the token server to the vehicle as a client. The vehicle waits for a random period of time within a configurable time interval before the vehicle uses the fleet token to transmit the data to the computer, such that a correlation between the vehicle and the transmitted data via a time measurement is prevented.
