The Rapid Rise of License Plate Readers
An anonymous reader writes "Today, tens of thousands of license plate readers (LPRs) are being used by law enforcement agencies all over the country—practically every week, local media around the country report on some LPR expansion. But the system's unchecked and largely unmonitored use raises significant privacy concerns. License plates, dates, times, and locations of all cars seen are kept in law enforcement databases for months or even years at a time. In the worst case, the New York State Police keeps all of its LPR data indefinitely. No universal standard governs how long data can or should be retained."
the patriot acts, drones and the war on terror was just a paranoid delusion?
I thought we past thinking we had any privacy left.
Do you really have an expectation of privacy over the license plate hanging on your car bumper?
Aren't license plates like the opposite of private?
You are welcome on my lawn.
I see it differently. I welcome such "progress" because it can only have one eventual outcome - the destruction of the current order. So by all means, push a little harder. Just a little more...
Seven puppies were harmed during the making of this post.
Get license plate spray. It works.
Only in the case of the now out-dated cameras that use a flash.
The kind of ANPR systems that have become ubiquitous in recent years don't use a flash.
However, I've been thinking that a clear license plate cover that embedded infra-red LEDs in strategic locations would be useful in obscuring the number to cameras - many (most?) of which are sensitive to IR in order to improve capture quality in low-light conditions - without being obvious to the naked eye.
When information is power, privacy is freedom.
What's the difference between hiring enough people to write down the license plates as people drive by?
One is not viable, and the other is. Of course, if you were somehow able to hire enough people to do the job, I'd say that would be an invasion of privacy, too.
But again, hiring the required amount of people to perform such a task is nearly impossible. People don't catch everything or have perfect memories, either.
Filthy, filthy copyrapists!
Every Android device is constantly tracked by Google. You can see this on Google Maps...check out the accuracy and detail of the traffic overlay. Apple does the same thing with iPhones. Both companies comply willingly with law enforcement requests for tracking data. So not only can they read your plate, but they can tell who is in the car with you, where you go, and where you stay.
Is all this information good, or bad? YES! This information can be used to bring about justice, or it can be grossly abused.
Wouldn't have believed it if I hadn't seen it. I'm sure eventually they'll come out with cameras that aren't fooled. And my first thought at that was, good, make the 'em spend money buying new equipment. Then I realized whose money it is they will be spending.
How about we make a bunch of signs that are pictures of different license plates, and place them randomly about town? Swap them out every few days, and change the plates, and soon the cops DB will be full of bad data.
Or pull a Little Bobby Tables, and have an image of a plate that ends in an SQL injection
Lol, you should check out this TV series called Mythbusters. They would laugh at your foolish lies. And then prove you utterly wrong.

You're messin' with my Zen Thing, man.....
We needs amendments to the US constitution to protect us from digital-based spying. The founders intended for the constitution to be amended often so that it could evolve and grow better. The digital awakening means that it needs to evolve and fast. There's no reason that law-abiding citizens should be monitored constantly. We are moving to a world were government knows everything about what you do. Only the historically naive would claim that the United States is immune to future political situations where that information, even if totally legal, could be used to blackmail, marginalize, jail, or even kill you. Unfortunately there is nothing to prevent such databases from being created. That is why we must be given new rights to protect us from them.
I think things are going to have to get a LOT worse (not jsut "a little more..." for most Americans before they get off the couch and cause the destruction of the current order. Unfortunately I don't think that there's enough care out there for any meaningful push back towards a decent state. This means we're going to be stuck on this slow downward spiral for a while now. The worst part is that by the time most Americans wake up, first they will be called hippies and minimized in the media, and then the technology used by the police state will be too advanced for any meaningful change to occur. We will simply all end up being labelled as terrorists or have criminal records for showing up at an anti-whatever rally.

What's the difference between hiring enough people to write down the license plates as people drive by?
This should be the same question in almost all technology privacy questions. With enough people, could you perform the same level of tracking/facial recognition/technology boogeyman?
There is no difference in the end, the same privacy issues would arise, I dont see your point. Human or computer, it is still just as creepy and concerning.
But computers/cameras can do it way better, faster, more accurately, cheaper, require less maintenance, are smaller, less obvious, require less effort to create the system, can provide tracking data in real-time, analyse and store tracking data forever.....dude, you got all day? I could go on and on and on...

If we're gonna bitch about not being able to take pictures in public places, we can't bitch about the gov't taking pictures in public places.
I feel like if the anarcho-libertarians around here go their way, civilians would all have modern technology while cops are forced to run around in loincloths with sharpened sticks.
No, they just wouldn't be allowed to monitor absolutely everything and everyone just because they want to catch a few people they deem criminals. How awful that is.
Filthy, filthy copyrapists!
It's not a matter of what technology the cops are allowed to use, it's a matter of how they use it.
Cops, with a warrant, are allowed to do all sorts of stuff. They can listen to your phone calls or search your house. As long as there's some level of checks and balances on it, I can accept that. I have this crazy idea here -- hear me out -- that before the police put together a database of everywhere my car has been pretty much forever, they should need a warrant for that too. And it'd be kind of nice if they had to get rid of that data after a certain point if it didn't enable them to build a case.

No, it's general knowledge about what public street you were on at the time of the photo. It doesn't tell them anything about a specific place you are going. At best (worst?) they might see a still photo of you turning in to a parking spot or parked along a road.
Sorry. But you don't see the whole picture. License plate readers are not just single photos. It is about movement of individuals And not just one suspect, but everyone. It is automated and turns the where-abouts of individuals into a searchable database. Combined with security cameras, face recognition, and cell phone records they can give you a very accurate description of someone's movements.
So what? NY (eh, Bloomberg) is proud, that with their new technology (provided by Microsoft) they can automatically search for certain suspects. Looking for someone in a blue jacket? They can now automatically pull up surveillance of anyone in a blue jacket. And they keep video records for the last 30 days (Other records for years). They can probably match that to what car that person drove, what store he/she entered (nice pictures there), or whether she/he used the subway. They are working on software to automatically detect suspicious activity.
Once you have all this data, it would be very easy for some other unnamed agency to use it to match movement data of different individuals and come up with a list of possible contacts.
Now imagine that technology in the hand of a repressive police state. The White Rose (students who distributed leaflets against Hitler) lasted about 9 months before they were beheaded. A janitor caught them distributing leaflets. With Bloomberg/Microsoft's new Information Awareness they would last a couple hours.
As a resident of NYS, the highest taxed state in the country, the expense of this is far more upsetting to me than the privacy implications.
Go green: turn off your refrigerator.
Hello, I see a *lot* of negative privacy concerns on this post, but I see it differently. I've felt for over a decade the police should have license plate scanners. Then when they tie it into a database of stolen cars, or cars used in recent untried crimes, it would come up as a positive, and the cop could pull the car over.
Isn't there any love for police here being able to do their job more effectively? Every civilized nation needs a police force. So even if you don't like the current government, a new government still would need police. We should therefore help our police to be empowered to solve the crimes they're commonly tackling.
God spoke to me
As a result of this rapid expansion of private monitoring, the company recently won a $25,000 contract with Immigration and Customs Enforcement to provide a database that would help locate "fugitive aliens."
I don't get it. What does an agency whose primary mandate is to shut down Web sites and seize domain names need LPR data for? Are people driving server farms around in trucks?
That may not be as crazy at it sounds.
"To those who are overly cautious, everything is impossible. "
I see two common responses to this:
1) This technology will lead to a loss of privacy and abuses by police, therefore it should be stopped
or
2) This technology will enable police to find and catch criminals more quickly and effectively, therefore it should be allowed.
The truth is, both reactions are correct -- but the issue is typically presented as a tradeoff: we can have our privacy OR better law enforcement, but not both.
But what fun is that? I want both. And since we are all clever Bagginses here on Slashdot, perhaps someone can think of an LPR system that would allow police to track down criminals quickly, and yet still by highly resistant to privacy loss or abuse. I recognize that such a design is non-trivial, but in a world where people come up with clever systems such as BitCoin, I don't think it's necessarily impossible either. It just takes some serious thought, and getting past the "ooh, new technology is scary" stage.
I don't care if it's 90,000 hectares. That lake was not my doing.
i was just thinking, would privacy screens (meant for laptops) work on your license plate?
directly behind (police for example) you can see it fine, but directly overhead or from a side angle (cameras) are obscured.
thoughts?

They can require a great many things of you for being allowed to drive on the public road system. Car insurance for example; you don't have to buy it but then you do not have to drive.
You could be required to have unique IDs on your car for easy identification (aka license plates) and you have no recourse unless you get a huge number of voters together to change that requirement.
If you do not want to be tracked, you will have to use another means of transportation - you have the right to primitive mobility.

I know their vehicle, shit I even know their license plate, whats the difference if I report it or a camera does?
Yea I am being tracked as well, but theres this thing called an if statement ... if (driver == asshole) flag; else break
My license plate is out there for the world to see. So what? So is my face and my fingerprints. Big freaking deal. People could track people centuries ago, they're just faster now.
Wouldn't have matter if it did work. Texas law prohibits any and all methods of obstructing license plates (that would otherwise obstruct automated OCR based technology).

I wouldn't be surprised if the next version of plates have RFID tags built into them. It would certainly make their job easier and the technology would be cheaper than it is with complicated and software. It would also cost the tax payer less money in equipment costs. Think of it as rape with lube thrown in to make the experience better. And remember to say "Thank You".
You're welcome citizen.
Life is not for the lazy.
Only those of us who decide to NOT own/carry a cell phone for geolocation privacy issues are allowed to bitch about this.
So recording personal information in a database by a private corporation (run by civilians), would be allowed to happen in your country? On public land?
So then the premise that civilians are held to a less account is clearly false then, yes?
Technology can be used for good or bad purposes. References: The entirety of human history

I had a company spokeperson at my university lecturing about the benefits of Bluetooth tracking. They stated it was used for improving traffic, but at what cost?
Many countries also have electronic tolling booths that require RFID devices in cars (it's called eToll/GoVia in Australia). So it's not only license plate readers that people have to watch out for.
And it will likely be replaced with a worse order.

Your obviously brilliant point is lost on the rest of us who don't read your language. What did you say?
I wonder if that means that if you have your car stolen, you would just be able to go to the police and they would tell you exactly where it is.
Sure, one wants the police to have good tools. The thing is, these tools should only be used in genuine criminal cases.
How about this:
- The license plate scanners are great, they run all the time, scanning every plate they see.
- The data on the plate (this car was here at this time) only if the plate is in a list of accepted cases. Otherwise the data is immediately discarded
- A plate can only be placed in the list if the car has been reported as stolen, or if a judge has issued a warrant.
- Plates may only remain in the list for a limited time, for example, as specified in the warrant.
- If data collected on a plate is not needed (e.g., no criminal complaint results from a warrant) the data is deleted.
This way, the police have a good tool to use, and the privacy rights of innocent citizens are not infringed.
Enjoy life! This is not a dress rehearsal.
In principle, the govt should have the right to take pictures anywhere in public. The counter-argument is that *they* are forcing every car to have license plates, and it's all part of a tracking machinery. It would be like forcing everyone to wear a baseball cap with a barcode on it.
On the third hand, the police could just do facial recognition instead. I don't believe the tech is mature enough yet, but that's not a good thing to rely on. Even without a government photo ID database, they could just store anonymous faces and opportunistically assign names to them. So there's really no principle on which I can base my opinion, if I insist that restricting people (including governments) from using technology that doesn't harm people is wrong. The government even owns the roads on which they place the cameras.
So how should we go about implementing TOR for real life? I envision it would involve lorries full of SUVs full of motorcycles.
Almost everywhere you go in britain now (certainly in big cities) you see ANPR cameras slung up above the road. Sure, it has helped catch a few criminals but at what cost to personal privacy? You could argue that no one should be allowed curtains in their house because that way the police could see any crimes being committed such as burglary or rape. But I can't see many people going along with that. The current generation of politicians and police commanders just can't see the road to hell they're leading us down.
These systems will be abused more often than they will be useful. I know what you did last night!
A famous person committed suicide some years ago here. Police stats showed that her 'police record' was accessed a couple of thousand times by cops that had nothing to do with the case.
They abuse the system to check upon there new neighbor, the daughters bf and the likes.
A centralized system detecting licence plates will now be used to check upon the wife and kids more often than the original intent.
It's just one big google for them.
I argued with the cop responsible for bringing this technology to my region. I love the technology, and think it's very useful. However, I ALSO think it ought to have a zero-minute retention period except for hits against flagged plates.
Apparently, the police think it's a great idea to know where every plate was as far back as they can store the data - and since it only takes a short text string and a small confirming .jpg image for each plate, they can keep an awful lot of data. While there's great data mining potential there, like finding which plates were present at similar crimes across a long period of time to help identify suspects, I can just see so much more room for Orwellian abuse.
So how bout this one? Each camera receives over the network the hash of licence plates for which a search has been ordered. The camera only sends hits for plates that hash to one of those values. That way the compromise of the camera does not divulge which license plates are being searched for, and the police don't get to know where everyone is, only the license plates they have marked as interesting for that area. They could mark every car registered in that county, but we could go further and require some amount of judicial overview to add a hash, or simply probable cause.
refactor the law, its bloated, confusing and unmaintainable.
Do you want to change the laws? It's simple:
Just crowd source the same technology, keep track of all police cars and government officials. Watch new privacy laws created with extreme speed and efficiency.
It's never a problem when privacy concerns affect your average citizen. But when it affects those with those who are privileged it will always be a top priority to fix.
While I, like many others, am concerned with the erosion of privacy, I fail to see how law enforcement taking a picture of your license plate that is publicly displayed while you are on a public street can be construed as an invasion of privacy. Since anybody can see/view your license plate in these situations, having a computer scan it instead of an individual writing it down as you pass by is no different. If you use a pay-card to pay your tolls, they also know every time you drive on the toll road. Again, that is not an invasion of privacy as you are in a public space.
The concerns with this, from my perspective, are what are the potential misuses of this data, and why does it need to be stored for such a long period (indefinitely in some places)?
And draw even more attention to oneself?
Give me Classic Slashdot or give me death!
One would think that the ostensibly geeky audience of this site would understand that technology advances, and when it does, it helps everyone
Yes, it helps people who want to abuse the technology as much as it helps those who want to use it to make things better. We need to put limits on the former.
Give me Classic Slashdot or give me death!
License plates are the first step.
Then facial recognition for people walking in the streets. Same logic can be applied to walking in public. Then as soon as you connect to the internet every site you visit and every post is considered public domain information.
You're on a slippery slope where there is no end.
That and i mean come on. Police search for stolen property? What fairy land reality are you living in?
Just curious here, but what makes people think that traveling anywhere in a public place with a unique identifier like a license plate somehow constitutes a private act that deserves any form of protection?
If you have a tendency to accelerate through yellow lights on a regular basis, or make rolling stops, and there are Traffic Cameras, (like in Toronto, or New York City) chances are it will show a trend and sooner or later, when you finally get into an accident. there will be a Mountain of evidence that will just 'appear' in court (that someone could Pay For) when the injured party decides to sue you!
You drive down the street, anyone can see you. Anyone with a camera, be it a phone, or even a Nintendo DS, can take a shot of you. If you go into a public place, guess what? People will See you! If you go anywhere there might be a camera, those images will be around as long as there's a means of storing them.
Welcome to the Digital Age! Anyone who thinks that data of any kind simply can't leak its way out of Vegas (or anywhere else) is deluding themselves in a very sad way. Anything that has been recorded will find its way into the public eye at the most inconvenient of times. Particularly, if there's any sort of Political Gain involved.
"What Happens in Vegas, stays in Vegas" is a myth.
I like the Jeff Dunham quote, myself: "What Happens in DC Stays on YouTube".
That's the ENTIRE point of a licence plate.
How can this be a violation of someone's privacy when the entire point of getting a licence plate is to register and identify your car as belonging to you.
It's the reason they exist, so when you break the law driving your vehicle, the cops can figure out who to arrest or write the ticket for.
Sure, it might suck for a cop to drive down the road and tag all the people that have committed a crime and then charge them accordingly. Sorry if you feel your right and privacy to COMMIT CRIME is in violation here.
What are people bitter about, getting caught?
Yes, there are going to be regulations and yes I am sure there will be a cop out there that will abuse this power at some point in time. But its why we have courts and laws and the right to challenge any charge or conviction against you.
I am tired of people that feel they are entitled to privacy outside their home. You are in a public venue the moment you step out of your front door and so technology identifying you is no different then a neighbor or friend or co-worker noticing you parked suspiciously outside another neighbor's house boning his wife. If you don't want to be caught don't do the crime, or at least use a little common sense when committing it (like take a bus or ride your bike) and simply accept responsibility when caught.
I haven't thought of anything clever to put here, but then again most of you haven't either.
I am OK with technology helping police do their jobs. The problem I have is their bosses (Government) sees fines as a source of income, Thus tries to setup laws in a way that makes it easier for people to break laws.
I haven't been in trouble for the following, but I found myself in the violation by mistake though.
Driving without an updated registration. What happened I moved, I changed my address for my license... However the DMV doesn't take you change of address for your license and apply it to your registration so when it was up to renewal I never got the paper work, then I realized after looking at my registration that the month was too late. Now with license plate readers I would expect unlike my address records the licence plate reader will be better integrated, then the worst part I will get a fine in the mail months, or years after I was driving illegally.
We even had a case in my City where people were getting Traffic Tickets Years after the incident because of automated readers just because the state hadn't got caught up with the paper work, and the City was short of cash so they just started giving tickets out, for violations that were years old.
Fines for breaking the law shouldn't go to the government, it should go to the victim(s) or if there aren't any then it should go to an approved charity of your choosing (without a tax deduction) Perhaps then when making new laws and regulation they will focus more on the greater good then making it so people will find ways to collect money.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
This is just a further step in the evolutionary path of law enforcement. If you have a camera recording a person's face, or in this case, a license plate, you don't have to get off your fat ass and interact with the people you were sworn to protect. And yes, with every step along the way, this country is turning into the totalitarian state that the founding fathers (Benjamin Franklin, in particular, comes to mind) warned us against. Thank goodness our citizens are armed to the teeth so that when push comes to shove we'll have a bloodbath of epic proportions.
Ya. I work in transportation and LPR is a growing successful way to capture a massive amount of data while not doing much. You can send enforcement officers out to check for permits, or you can use permitless LPR systems with which people register their plates. If someone isn't on the list, ticket! If they are, keep on driving.
In the parking world, the list of read plates are expunged nightly or at LEAST weekly.
It would also cost the tax payer less money in equipment costs.
BWAHHAHAHAA since when has anything the government improved on saved the taxpayer money?
Karnal
I always imagine that these tools, and it seems there are more of them each day, will lead to complacency, the evidence seems so very compelling when it comes from such a fancy system. However, one day someone will game the system; maybe the villain just bolted his license plates onto the back of some unsuspecting stooge's car, or had a second set of plates, or even put out a dozen sets of duplicate plates, or put different plates on the front and the back of the car or do any number of things that simply makes the system unreliable.
Then the system will wind up providing an alibi for someone we would all have rather seen in gaol and its veracity will go unchallenged because it is so whiz-bang.

Indeed. This is more like having the Paparazzi on every street corner, and you're a person of interest.
We *know* that those "higher up" don't like that, so why should we put up with it from cameras.
1. Limited resources. We only have so many public funds to support public safety and law enforcement. I would rather it all be focused on areas of known or likely crime.
2. The principle of limited government. In the USA, we still have the tenuous idea (opposed by the progressives) that governments have only the rights we give them. Police may not form policies and expend funds on ubiquitous surveillance unless we pass laws (at state or local levels) that give them that right. There are everyday, internal polices (like vehicle maintenance, hiring, salary, etc.) that would be unreasonable for the people to micromanage, but clearly a major change in police policy like moving focus from targeted enforcement to general surveillance is dangerous to human rights.

I don't know why we need to go through this every damn time
Because you are talking about something different.
Many (most?) people have no issue whatsoever with police being able use an array of cameras to read every plate near them, and alert the officer that the red Ford two lanes to the left is reported stolen. I know I don't.
Many (most?) people have BIG issues with a database that logs the location of every license plate to be later reported on when you want to track where a person was, or find all cars that were near X area at Y time.
If someone says "I don't see what why it is a privacy violation for a computer to read a plate" and you respond with "tracking and correlation", you're going to get tired of explaining your point to people that might actually agree with you.
TL;DR
Automated reading of plates does not automatically mean logging and recording the location of them.

License plate readers are a great idea! Just this past week, it helped Mr. Police Officer know that my car registration was out of date. Mr. Police Officer was of course very polite as he told me about the $200 fine. Very handy! Now the government can raise revenue more easily!
Love sees no species.
So recording personal information in a database by a private corporation (run by civilians), would be allowed to happen in your country? On public land?
We're not talking about personal information. We're talking about license plates. I guarantee you that millions of license plate images have been captured by Google's Street View. Whoops, there goes your argument.

One man's good is another's bad. Keeping track of where cars are will help reduce car thefts and kidnappings, at the cost of ...what, exactly? You're afraid that the fact that you visit an adult film store might show up in a database, as if anyone in the world would care?
The worst part is that by the time most Americans wake up, first they will be called hippies and minimized in the media, and then the technology used by the police state will be too advanced for any meaningful change to occur. We will simply all end up being labelled as terrorists or have criminal records for showing up at an anti-whatever rally.
No need for police intervention, soon the corporate world will be effectively more powerful for this sort of thing. Show up at a protest with your phone turned on (oops! Not like the network would be online over a protest anyways), get tagged as anti-establishment/anti-authoritarian in a private tracking system like Trapwire, become as hard to hire as an ex-con, and the cops will keep a closer eye on you as well.
