The device (2) has a satellite navigation receiver for continuously generating location data for a processing and transmitting/receiving unit of the vehicle device. A trusted-element processor logs a time segment of the generated location data and cryptographically signs the time segment. The processor starts the logging upon detection of a predefined time or predefined location of vehicle device and carries out the logging for predefined time segment. The processor detects predefined location based on external location data received from proximate vehicle devices through ad hoc network. Independent claims are included for the following: (1) method for logging location data of location-recording vehicle device of road toll system; and (2) ad hoc network. |
