METHOD FOR CAPTURING IMAGES OF VEHICLES
First Claim
1. A method for capturing images of vehicles passing through a section between an entry and an exit at excessive speeds, the method comprising:
- generating a random access identifier for a vehicle passing the entry;
capturing an entry image of the vehicle at the entry and storing the entry image and the random access identifier in a first memory, wherein the first memory is accessible only via said random access identifier;
recording an entry time and at least one entry identifier of the vehicle at the entry, forming an encrypted or hashed value of said entry identifier, and storing the entry time, the encrypted or hashed value and the random access identifier as a data set in a second memory;
recording an exit time and at least one exit identifier of the vehicle at the exit, forming an encrypted or hashed value of the exit identifier, and ascertaining a data set which has the same encrypted or hashed value from the second memory; and
if the exit time lies within a preset first time span from the entry time of said data set, using the random access identifier from said data set for accessing the first memory to retrieve the stored entry image of the vehicle.

Abstract
A method for capturing images of vehicles at excessive speeds including: generating a random access identifier for and capturing an image of the vehicle at the entry and storing them in a first memory which can only be accessed via the access identifier, recording the entry time and an entry identifier at the entry, forming an encrypted or hashed value of the entry identifier and storing the entry time, the value and the access identifier as a data set in a second memory, recording the exit time and an exit identifier at the exit, forming an encrypted or hashed value of the exit identifier and ascertaining the data set with it from the second memory. If the exit time lies within a preset time span from the entry time, using the access identifier for accessing the first memory to retrieve the stored entry image of the vehicle.
