NMA Reboot: Are the Feds trying to Rebrand License Plate Readers?


This weekly post features recent news stories that highlight and update themes previously covered throughout NMA E-Newsletters and Alerts.

Editor’s Note: Police agencies across the country are facing increased scrutiny over the use of automated license plate readers (ALPRs), cameras that capture vehicle license plate data. With enough cameras, motorists can be tracked everywhere they go 24 hours a day. Privacy and civil rights advocates have been outspoken with their concerns over how—and how long—the information is stored, who has access to it and how it is shared. In what may be a response to this growing pushback, the U.S. Department of Transportation is soliciting bids to research the impact of plate readers on highway safety. Could this be an attempt to make plate readers more publically palatable by rebranding them as “safety devices” rather than law enforcement/surveillance/tracking devices? Only time will tell. 

The NMA threw up the warning flag on plate readers years ago and has continued to point out the privacy challenges they pose. Below is one of our earlier e-newsletters on the subject. 

 

NMA E-Newsletter #61: Here, There, Everywhere 

The title refers to cameras on the road, but not the usual red-light or speed cameras that we invariably write about. This newsletter is about ALPR.

What the heck is ALPR, and why should you be aware of it? Automatic License Plate Recognition applications are proliferating and are mobile. Many electronic plate-reading systems are mounted within cruising vehicles, and are operated by law enforcement agencies or even private, for-profit companies. ALPR systems capture and process the license plate information of any and all cars, motorcycles and trucks that cross the path of the host vehicle.

High-speed digital cameras are mounted around the periphery of the ALPR-equipped vehicle so that photographic evidence of passing vehicles, even at freeway speeds, can be gathered. License plate numbers are converted by optical recognition software to text, which can then be checked against a variety of databases, depending upon the intent of the data-capturer.

The law enforcement application is pretty straightforward. Plate numbers are compared to lists of stolen vehicles or owners with expired registrations, outstanding fines, or open arrest warrants. The mobile ALPR unit is equipped with a laptop computer, so a match can be found almost instantaneously and the location of the flagged vehicle pinpointed in real time.

Private applications of ALPR include automobile repossessions by lenders. A tow truck can be called in immediately upon locating a flagged license plate, allowing the repo man to keep motoring along on his quest to capture more license plate images and delinquent borrowers.

Much like any program that gathers massive amounts of data, the culling of the innocent from the guilty is not a perfect process; too many of the former can be swept into the process. Database information may be incorrect, license plates can be switched, vehicle registrations may not have been transferred properly to new owners — any number of things can go wrong, causing an innocent party to have to endure the hassle of a towed vehicle, or much worse if a false arrest is involved.

For more information about how ALPR works, you can view the video at the bottom of this post which shows a plate-recognition program in action by Central Florida law enforcement. The constant clicking of the cameras capturing license plate data throughout the video will give you some idea of the scope of such a program.

    Get over it! You have no privacy in the United States. Through legislation is the only way your lying, self-serving politicians are going to protect the Citizens from increasing government intrusion in their lives but you can see how well this has been going.

    Like nearly every other traffic/vehicle law passed, ALPR's will become common place because of the money to be made.

  2. Brother John says:

    Well, since "speeding" has been branded as "aggressive" and "dangerous" — and readers of some seriously right-leaning publications are horrified to hear libertarian talk on the highway — then anything and everything can be labeled as a "safety" device.

    Too many people have drank this flavor of Kool-Aid, and the illusion of safety has been accepted in place of liberty.

    Nothing that is capable of collecting or storing data of any kind ought to be labeled a "safety" device, because it does literally nothing to create safe conditions. It needs to be properly thought of as a tracking/spying device and nothing more.

    And on top of this, I have yet to see any optical character recognition work better than about maybe 50-60%, which is nowhere near good enough. In fact, if it isn't 100%, it cannot be allowed to be used in court, or even to issue tickets.
