Claims (13)

An identification information determination device that determines whether vehicle identification information is illegal,
An acquisition unit for acquiring identification information of a vehicle passing through a plurality of points and a passing time point related to the identification information;
A calculation unit that calculates travel time between points based on the identification information acquired by the acquisition unit and the passage time related to the identification information;
An identification information determination apparatus comprising: a determination unit that determines that the identification information is invalid when the travel time calculated by the calculation unit is equal to or less than a predetermined threshold time between the points.   The identification information determination apparatus according to claim 1, further comprising: an output unit that outputs fraud identification information corresponding to fraud when the determination unit determines that the identification information is invalid. A storage unit for storing the vehicle regular identification information and the vehicle image in association with each other;
The identification information determination apparatus according to claim 2, further comprising: a display unit that displays an image of the vehicle related to regular identification information equivalent to the fraud identification information when the fraud identification information is output by the output unit.   The identification information determination according to any one of claims 1 to 3, further comprising: an unauthorized information storage unit that stores unauthorized identification information corresponding to fraud when the determination unit determines that the identification information is unauthorized. apparatus. The identification information is
