New Software Puts License Plate Scanners Into Citizens' Hands (arstechnica.com)

An anonymous reader writes: Automated license plate readers have become a serious point of contention between law enforcement and privacy-minded citizens. But the advance of technology might make it a moot point — with some open source software and a cheap webcam, anyone can now start cataloging the cars visiting their street. A two-man team developed OpenALPR and started distributing it for free, along with the source code. Law enforcement and the agencies that build their plate scanners have argued in favor of the legality of such data collection, so it's not like they can suddenly start cracking down on private citizens doing the same. "An enterprising person could even use a car-mounted camera and create a mobile plate hunting device along the lines of what many police agencies already use." Is this particular privacy fight one that's still winnable?

  5. District court by Okian+Warrior · · Score: 5, Interesting

    I was summoned to district court for an 8:00 AM hearing, and discovered - quite by accident - that the judge didn't bother to arrive until 10:00 AM. My lawyer mentioned that this was typical.

    Everyone had to wait around and was forced to listen to some insipid video about drunk driving (irrelevant to my landlord/tenant purpose) for two hours over and over before the judge bothered to arrive.

    I've often wondered how useful it would be to mount a trail camera behind the courthouse and log the judge's arrival times, and then make that information public. Say, 6 months of study.

    I wonder how long it will be before someone modifies this software to automatically log the comings and goings of government servants to a public website.

      I considered cobbling together a system like this in 2011, coupled with a speed gun and driver photographing camera - mounted in my mailbox. Speed limit on our street is 20mph, but we get cars coming around our (blind) curve at 50+ at all hours - perhaps only 8 or 10 times a month, often enough to be a concern, not often enough to easily catch.

      I happened to hear one coming once while I was out walking, and managed to get a visual ID of the occupants, that one was a divorced dad bringing his daughter home with an attitude. Others I glimpsed and recognized the vehicles as residents in the neighborhood. Having the data won't get me citizens' arrests, or shame the parties into "growing up" and not driving like a teenager (at 50+ they're unlikely to change), but it would sway the neighborhood governance committee about the necessity for additional speed bumps.

      Better solution: we moved out of the neighborhood with the board of governors and glass smooth winding roads through the forest - now we live at the end of a bumpy road, no more speeders, and no more board of governors to screw with, win-win.

      You are so wrong.

      Imagine I own a store and I want to know as much about my customers as possible. I can place this license plate reader on the entrances and exits to my parking lot. With each purchase I have access to what was purchased when. With a little bit of statistical analysis I can place plates to buyers by comparing when I saw a car come and go to the time stamp on purchases.

      For the rare visitor I may only know the state and county of the customer from the automated data. If the software does not already include this feature it would be trivial to add a function to keep a photo of the car along with the time, date, and other data. I now can gather info on the make, model, and year of the vehicle, as well as it's general condition. This can give indications of income and potentially other demographics. Is it a dirty truck? Possibly a farmer, rancher, construction type of employment. Is it an old Cadillac in impeccable condition? Car collector type. Beat up old Cadillac? Possibly not so well off, but was before.

      Cross reference this with credit card data and I have the name of the customer, as well as any other information the credit card company is willing to share. Then flip this around, perhaps the credit card company is willing to buy this information from me. The credit card company now has an incentive to encourage other stores to place cameras on their parking lots.

      Let's take this a bit further and suppose I give out "anonymous" surveys to customers. The customer doesn't have to put their name on the survey, or their license plate number, just knowing when they filled it out can give a high correlation to the customer. On the survey I could also ask them what car maker they prefer, as a large number of people will put on there what they currently drive. Perhaps I ask what brand of tires they buy, again I can compare this to the photo to verify identity.

      If they buy with cash there are still ways to match the customer to the vehicle and purchase. I can ask if they are willing to apply for a store credit card, or "discount club". With facial recognition software piled on top this can get even more interesting. I can match people that drive the same car. Driving the same vehicle would imply family, friends, roommates, or other close relationship.

      All this data does not need to be gathered before it is valuable. I can gather this data for some anonymous person for a very long time, once I get a name then I now have a long history to mine. Again, I don't have to gather all this data myself, I can buy pieces of the data from others, perhaps buying it with the data that I gathered.

      Oh, another thing just came to me, custom license plates. There are license plates for things like volunteer firefighters, veterans, radio amateurs, and on and on. This adds further value to the data.

      Someone that wants to track even more will log the small talk at the register. Any big plans tonight? Nope, I'm working again tonight. Type a note into the register, night shift worker.

      All kinds of data can be obtained. It's just a matter of how much effort one is willing to invest. With software that can automate the logging of license plates the amount of effort required just got a lot smaller.

    Honestly it depends on how you look at it. You can make a bomb out of items in Walmart. If I started to argue that because you can do that, we shouldn't produce those items, it would be a moot point. Conversely if I started to argue we should all make bombs because it's inevitable, that too would be a moot point. The point is, don't mix those things to make a bomb, more simply, don't be a dick. This includes putting me on a watchlist because I just said, "I can make a bomb" and start watching me, trying to get me to do it. That is what the Constitution was trying to avoid in respecting people's privacy. You can make the case that anyone is potentially dangerous and we should just start treating each other like adults and realize that processing power is cheap and sensor technology has become high quality and also cheap. Source code for decent data processing is free, yet you need not slap the label, "Bad guy detector" on your setup because you will find in fear what you are looking for if you're paranoid enough.

In April, however, I also added a plate recognition subsystem. It performs surprisingly well for such a cheap solution. Now I can tag plate numbers and assign notifications for specific tags. For example I receive a sound notification when I am passing my boss/friends/work colleagues. I also have a separate group for people who I have seen driving badly before.
