License-Plate Scanning by Helicopter
The fictional police spy helicopter from the movie Blue Thunder is taking a big step toward becoming a reality. Police in the UK have successfully tested a 160 MPH helicopter that can read license plates from as much as 2,000 feet in the air. The Eurocopter EC135 is equipped with a camera capable of scanning 5 cars every second. Essex Police Inspector Paul Moor told the Daily Star newspaper: "This is all about denying criminals the use of the road. Using a number plate recognition camera from the air means crooks will have nowhere to hide."
The use of Automated Plate Number Recognition (ANPR) is growing. ANPR devices photograph vehicles and then use optical character recognition to extract license plate numbers and match them with any selected databases. The devices use infrared sensors to avoid the need for a flash and to operate in all weather conditions.
Of course, once the system is in place it will be used for privacy violations that we can't even conceive of.
One of the companies that sells the camera scanning equipment touts it's potential for marketing applications. "Once the number plate has been successfully 'captured' applications for it's use are limited only by imagination and almost anything is possible," Westminister International says on its website. UK police also envision a national database that holds time and location data on every vehicle scanned. "This data warehouse would also hold ANPR reads and hits as a further source of vehicle intelligence, providing great benefits to major crime and terrorism enquiries," a Home Office proposal explains.
The only way to maintain security is not to field this sort of system in the first place.
