EFF Wins Access To License Plate Reader Data To Study Law Enforcement Use 62

An anonymous reader quotes a report from the Electronic Frontier Foundation: Electronic Frontier Foundation (EFF) and the American Civil Liberties Union Foundation of Southern California (ACLU SoCal) have reached an agreement with Los Angeles law enforcement agencies under which the police and sheriff's departments will turn over license plate data they indiscriminately collected on millions of law-abiding drivers in Southern California. The data, which has been deidentified to protect drivers' privacy, will allow EFF and ACLU SoCal to learn how the agencies are using automated license plate reader (ALPR) systems throughout the city and county of Los Angeles and educate the public on the privacy risks posed by this intrusive technology. A weeks' worth of data, composed of nearly 3 million data points, will be examined.

ALPR systems include cameras mounted on police cars and at fixed locations that scan every license plate that comes into view -- up to 1,800 plates per minute. They record data on each plate, including the precise time, date, and place it was encountered. The two Los Angeles agencies scan about 3 million plates every week and store the data for years at a time. Using this data, police can learn where we were in the past and infer intimate details of our daily lives such as where we work and live, who our friends are, what religious or political activities we attend, and much more. EFF and ACLU SoCal reached the agreement with the Los Angeles Police and Sheriff's Departments after winning a precedent-setting decision in 2017 from the California Supreme Court in our public records lawsuit against the two agencies. The court held that the data are not investigative records under the California Public Records Act that law enforcement can keep secret.
"After six years of litigation, EFF and ACLU SoCal are finally getting access to millions of ALPR scans that will shed light on how the technology is being used, where it's being used, and how it affects people's privacy," said EFF Surveillance Litigation Director Jennifer Lynch. "We persevered and won a tough battle against law enforcement agencies that wanted to keep this information from the public. We have a right to information about how government agencies are using high-tech systems to track our locations, surveil our neighborhoods, and collect private information without our knowledge and consent."

    It hardly matter, private companies do a lot of the license plate scanning then license their database to law enforcement. Bail bondsman and repo men cruise around recording everything to help locate or predict where to find people (the person of interest, their family, their friends) or cars. They will cruise up and down parking lots at shopping centers and stadiums just searching for a random hit on someone with a warrant or a car behind on payments.

    This is not a law enforcement specific problem.

      Why don't you make that kind of thing illegal?

      It's a serious question, why does the US allow it when many other countries do not? It is just that the law has not kept pace with technology or is there some political or philosophical reason?

        I guess it is a question of what is actually being violated.

        A lot of our toll roads are now using license plate recognition. It works rather well. No stopping or slowing down, you just drive. You don't have to worry about having the right change, or where your EZ-Pass is.

          Toll roads can use number plates in Europe too, but they can only use the data for billing purposes. No marketing, no selling it. Data has to be deleted as soon as possible.

          You have to opt in too, by driving on that road and seeing all the signs. Not like the bounty hunter example.

            How do you know it isn't saved? I want that data saved, because I want to have access to if if needed. That's willful destruction of evidence.

            I've never found data that can't be helpful if it can be retrieved. My best example is many years ago, I saved my employer millions in a patent dispute because I was the only person involved with verifiable date that proved we were first. I've saved every email I've ever received or sent. It gets used all of the time for group forensics.

    They need to violate privacy to protect it?

    • by ediron2 ( 246908 )

      The information was ALREADY COLLECTED IN WAYS THAT MAY VIOLATE PRIVACY LAW. The EFF is asking to see the information collected; it's no more a violation of privacy than any attempt at oversight of corrupt practices is itself corruption.

  • The erosion of privacy should result in changes to the law. Until electronic surveillance reached the current stage with all sorts of automatic recognition like facial, gait and license plates, people had an expectation of privacy in the form of anonymity. Nobody could trace someone else unless they actually literally followed them or installed a radio transmitter, which normally would have a limited time span too.

    And absolutely nobody could do a retroactive trace — at least not unless somebody has in

      .....unless they read the unique identifier bolted to the outside of the vehicle.

      Granted, the scale of data collection creates new problems that should be legislated, but it wasn't like we were actually anonymous while driving before now.

      • .....unless they read the unique identifier bolted to the outside of the vehicle.

        Actually not really, as anonymity is a relative concept.

        To trace an individual before automation became really feasible, you would have to dedicate people who would follow/shadow the specific individual. And if you wanted to do it surreptitiously and for longer periods, quite a few people.

        Also, you could not easily go back in time and find out where that individual had been, say, a week ago or a month ago, as you would have to manually go through droves of surveillance videos. And going further back than a

    This is one of the nuanced areas where it would really help to have privacy laws that specifically target privacy rather than the collection of data. With data you can do so much both in terms of optimisation as well as safety. However the presence of this data presents a privacy risk.

    Somehow laws need to be written to protect privacy and yet allow data to improve the way we live at the same time. This is going to freak out Americans but in the Netherlands license plates are scanned constantly all the time for a variety of purposes, some for safety, some for environmental, and some for optimisation.

    e.g.
    - Safety - Don't try to drive an unregistered car in the Netherlands. It will be a very short adventure that nets you a nice fine.
    - Environmental - I drove in Germany in an environmental zone for a good 6 months before someone told me I needed a green sticker on my windshield to drive in the zone I did. I never got a fine, despite breaking the law daily. In Rotterdam they introduced a system where they simply scan your license plate and compare it against a database. In many places when you enter the city the license plate flashes up on a sign and you get either a green tick or a red cross along with an instruction to turn around or risk a fine.
    - Optimisation - I got a letter one day telling me that my car was logged in peak hour every work day on the same nasty highway and as such I was invited to join a peak hour avoidance scheme. I was given 120EUR a month in an escrow account and every time I my car was detected in peak hour 3EUR were deducted from that account. At the end of the month I received the balance. Doesn't sound like much but that scheme actually made a huge difference to traffic on that highway during peak hour, and best of all traffic remained improved after the scheme stopped as people got used to getting to work later or earlier.

    There's so much we can do with data, but man it's risky to have that much info if you distrust your government.

    • License plates have been scanned regularly for many years in the US. Not sure why people are freaking out about it now. How did they think automatic tolls or red light/speeding camera fines worked?

      • "How did they think automatic tolls or red light/speeding camera fines worked?"

      • Seriously. Cars aren't meant to be anonymous and their comings and goings completely secret. They have visible license plates on them.

        People have faces. When they go out in public it is expected that people will see them and be able to identify them, both where they are, and where they have been. They are in PUBLIC. Their identity is not meant to be secret.

          There's a difference between being visibly identifiable in public and having your whereabouts tracked, recorded, and stored for indefinite amounts of time, without so much as probable cause. It saddens me that this distinction needs to be pointed out to you.
    • I’m not against such data being collected and used in principle, but I do think there should be strict limits (with strict oversight and enforcement) on how that data can be used, with appropriate retention policies to match the approved use cases. So number plate data collected from highways should only be used for purposes that pertain to the highway the camera is on. Enforcement of speed limits, environmental zones, flagging stolen vehicles, congestion management or road pricing are all ok. But not

        In a lot of developed countries like the whole EU there is regulation to assure the maximum allowed air pollution is not surpassed.

            Thing is, you can go wherever you want, just not with that old car.
            Also, these places typically have very good public transport so the need for a car is limited.
          • I couldn't deal with a government body telling where/when I could drive somewhere.

            So I take it you got in your parent's car as a 12 year old and went on your merry way while drunk out of your mind?
            Every government body in the world has restrictions in place on driving, including where/when (one way roads, road closures, when you are old enough and have a current license).

            Not just where and when as well, but also who (license holders), what (roadworthy tests), and how (speed limits).

            • Notice how CARB tests prevent certain vehicle classes from moving in certain places in the USA already?

              No. Never seen or heard of this.

              If you have a car that is licensed to drive in your state, you can go anywhere you want with it (public roads, which we all can drive on).

              The rest of your example was a bit inane.

              Yes, you have too be old enough and have a drivers license if you want to be on public roads (restrictions now there if driving on private property by the way).....but there are no restrictions

              • And yet you have to pass CARB tests for your CA car to be allowed in CA. Just because you found a loop hole or workaround doesn't make the point any less valid. You CANNOT just drive whatever the fuck you want where you want it. There are restrictions in place.

              • Actually, we do have a few such laws.

                Gross polluter laws allow the police to stop vehicles which are visibly polluting (belching clouds of smoke) and cite them or impound the vehicles for pollution violations.

                Local noise ordinances are frequently enforced on those who have modified their exhaust (straight pipes, etc.) I have personally seen cars show up at auto shows/meet ups and be impounded for violations of noise laws.

      • What the hell is an "environmental zone"?

        Sensitive areas usually heavily built up with large populations that could suffer negative effects of pollution.

        What does this have to do with driving a car somewhere?

        Huge populations with huge amounts of cars generate huge amounts of pollution in an area where the aforementioned huge population is exposed and as such it is hugely important to limit this effect. As such many countries in Europe ban vehicles that don't meet stricter emissions standards from heavily built up areas:

        Yes, history about a few select governments would, which is precisely why many modern governments have checks and balances in place to make them trustworthy.

        You've got it wrong. You bribe, er, donate to the police to collect all this data for your company then use/sell that as you see fit, outsourcing the collection costs to the taxpayers. Then you just offer the police chief or whoever a spot on your board or a "consulting" job after they retire.

  • This is a tough issue - exactly how much expectation of privacy is realistic for anyone driving a vehicle? By law, the vehicle has to be registered (public data), the roads are built and maintained with public money (taxes) by public organizations (governments). Taking the privacy concerns of drivers too far would leave the responsible citizen who reports a vehicle (description and license plate) for dangerous or suspected drunk driving open to legal action for violating the privacy of the apparently irre

      I think we will have to redefine the concept of expectation of privacy, as today's technology has made it possible to aggregate information gleaned from public spaces that goes far beyond what was possible at the turn of the millennium.

      The no expectation of privacy in public spaces has actually been eroded as historically no-one could realistically track everyone in public. These days that is no longer true (at least for heavily surveilled areas) and the law should be update
