A Threat to Privacy in the Expanded Use of License Plate-Scanning Cameras? (yahoo.com) 149

Long-time Slashdot reader BigVig209 shares a Chicago Tribune report "on how suburban police departments in the Chicago area use license plate cameras as a crime-fighting tool." Critics of the cameras note that only a tiny percentage of the billions of plates photographed lead to an arrest, and that the cameras generally haven't been shown to prevent crime. More importantly they say the devices are unregulated, track innocent people and can be misused to invade drivers' privacy. The controversy comes as suburban police departments continue to expand the use of the cameras to combat rising crime. Law enforcement officials say they are taking steps to safeguard the data. But privacy advocates say the state should pass a law to ensure against improper use of a nationwide surveillance system operated by private companies.

Across the Chicago area, one survey by the nonprofit watchdog group Muckrock found 88 cameras used by more than two dozen police agencies. In response to a surge in shootings, after much delay, state police are taking steps to add the cameras to area expressways. In the northwest suburbs, Vernon Hills and Niles are among several departments that have added license plate cameras recently. The city of Chicago has ordered more than 200 cameras for its squad cars. In Indiana, the city of Hammond has taken steps to record nearly every vehicle that comes into town.

Not all police like the devices. In the southwest suburbs, Darien and La Grange had issues in years past with the cameras making false readings, and some officers stopped using them...

Homeowner associations may also tie their cameras into the systems, which is what led to the arrest in Vernon Hills. One of the leading sellers of such cameras, Vigilant Solutions, a part of Chicago-based Motorola Solutions, has collected billions of license plate numbers in its National Vehicle Location Service. The database shares information from thousands of police agencies, and can be used to find cars across the country... Then there is the potential for abuse by police. One investigation found that officers nationwide misused agency databases hundreds of times, to check on ex-girlfriends, romantic rivals, or perceived enemies. To address those concerns, 16 states have passed laws restricting the use of the cameras.

The article cites an EFF survey which found 99.5% of scanned plates weren't under suspicion — "and that police shared their data with an average of 160 other agencies."

"Two big concerns the American Civil Liberties Union has always had about the cameras are that the information can be used to track the movements of the general population, and often is sold by operators to third parties like credit and insurance companies."

      Every step is a significant change. There are millions of cameras but at the moment nobody has access to all of them, and where there is access most of them don't do licence plate reading or facial recognition, and those that do mostly don't report that data back to a central government database in real-time.

          In the US, some jurisdictions did an end run by making it an administrative fee, thus no points and no going to court. You want to fight it, talk to the private company running the for profit red light camera. Some courts, IIRC, said, "Uh, can't do that" and a number of jurisdictions scrapped red light cameras for a variety of reasons.

        If the data isn't collected, then it can't be *USED*, period, even if that use might otherwise benefit society. Outlaw the misuse, and follow through with punishing people who misuse it.

      • I didn't say anything about gun registration, you did. My example was just that, an example. It wasn't meant to include all possible scenarios.

        Here's a real example: The Austin Bomber in 2018 was tracked through a license plate caught on camera. https://www.cnn.com/2018/03/22... [cnn.com] This is exactly the type of research I was describing.

  • I think it might help if we take a moment to consider the functional value that license plate scanners have.

    If a crime is committed and a report from the crime scene includes a license plate, then law enforcement can run the plate through the database linked to cameras and in a pretty short order, they may be able to determine most recent movements of the vehicle. The theory goes that this would be a reasonable mechanism for catching a criminal or suspected criminal in the event that a motor vehicle is u
    • 2. Presumption of Innocence Like IMSI Capture devices [the so-called "stingrays" that capture and track cell-phone use] ANPR (automatic number plate recognition) technology simply cannot be set to filter out people not suspects of committing a crime. In other words, at the point of data collection, [and given that the stated purpose of the technology is to catch criminals] every motorists is being presumed guilty. We could debate whether this amounts to a Fourth Amendment infringement, but even if not, it definitely steps over the line of "presumption of innocence".

      A presumption of innocence in court, not when a cop watches you. In many ways, this is like a high tech stakeout, except the ramifications are much wider reaching.

      3. Limited Value This might be a weaker argument and it will pivot around any data we might have concerning the "average number of passengers in a vehicle involved in a crime"... in that we have to question the value of establishing that "Vehicle X" passed a camera in "Location Y" at "Time Z" in the broader context. Can that establish the driver? The passengers? No. So now the value derived from the knowledge of the whereabouts of a vehicle at a precise moment in time is eroded, unless the driver is also the suspect.

      One value is in looking for patterns. What cars were at x, y, and z at times of interest.

      One of the most interesting elements of this yet to be evaluated [because getting the data would be hard] would be to ask a random sample of Police Forces: "OK, can you provide us with comprehensive details of all the cases where the use of ANPR technology either directly solved a crime or directly contributed to the solving of a crime?" We'd have to set some explicit limits about what we mean by "directly contributed to the solving of a crime" - for example, using images to trace the route of a stolen vehicle and being able to extrapolate a likely destination and then retrieving the vehicle - but that should be possible.

      Looking at tag data and linking it to crimes is far older than ALPR. IIRC, a parking ticket led to the "Son of Sam."

      As with any technology, there are good and bad uses. The challenge is in how do you control it.

      The agencies that purchase these cameras are either part of or funded by some form of government, whether that be federal, state or local [for example - in other countries it will be different].
