Another good reason to bike

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…

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.

The stated intent of the system is, predictably, “denying criminals the use of the road”. Just as predictably, other uses are already in the works:

Within the U.S., two cities are using the technology in a device called “Bootfinder” to identify and tow vehicles with unpaid parking tickets or even overdue library books. One woman’s car in Connecticut was towed out of her driveway because she had $85 in unpaid parking tickets.

and even more insidiously:

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.

<sigh>

I wonder if things like this or this work against such a system. (If they do, presumably it will then become illegal to obscure the overhead view of your license plate…)
