Claim:
1. A non-transitory computer-readable storage medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to cause the digital processing apparatus to perform operations comprising: for each of a plurality of vehicles, receiving at least one representation of information corresponding to a vehicle, said information characterizing a plurality of differences in measured positions of the vehicle between ending points of journeys taken by the vehicle and starting points of consecutive, new journeys taken by the vehicle, said ending points and said starting points being determined by a measuring device aboard the vehicle, said ending points being the last known positions of the vehicle in the journeys and said starting points being the positions of the vehicle when the measuring device is enabled at the start of consecutive, new journeys, said differences in measured positions arising where said ending points of journeys and said starting points of consecutive, new journeys as measured by the measuring device aboard the vehicle do not coincide with one another, said plurality of differences in measured positions being quantified by a plurality of respective distance differences; calculating from said at least one representation of said information at least one global representation of said information, said at least one global representation characterizing a plurality of distance differences for the plurality of vehicles; transmitting said at least one global representation of said information for receipt by a digital processing on-board unit in at least one of said plurality of vehicles, enabling said digital processing on-board unit to calculate at least one metric for detecting fraud in the use of the measuring device using the at least one global representation when the vehicle makes a new journey by identifying any anomaly among the plurality of the distance differences for the vehicle; and receiving a flag message from said digital processing on-board unit when potential fraud is detected to trigger enforcement at a central location through the automatic generation of a fine and an associated letter to a possible abuser of said measuring device.
