Sensors Gone Wild
tulanian writes "forbes.com has an interesting article on networked, intelligent sensors. It mentions an experiment done by DARPA where several dozen magnetic sensors were scattered along a road and passing vehicles could be identified by their magnetic signatures."
Now not only do they know how many people drive down the road, they also know their approximate wealth based up what they're driving? Yea....
Don't give me none of this "nature theme" business.
So does this mean, when your car begins to rust out, and it's magnetic fingerprint changes, you'll cease to exist?
0110100100100000011000010110110100100000011000100
a very MINOR operation by the car manufacturers could give each automobile a distinct magnetic signature, similar to a magnetic VIN. I dont think I'd want them able to track My driving habits...
Are there any insidious uses for this technology? There always are, but realistically what?
I could kinda see this being used for speed checking using the time elapsed between passing different sensors (like VASCAR) if the sensors could differentiate certain cars.
Or knowing where you are at any given time. Hmmm.
Any other suggestions?
I can imagine that many of the uses for these listed could be great, but over-reliance may be a problem. While it would be nice if everything like this worked like in Star Trek, I can imagine a story in the future where someone calls 911 about a bridge that looks about to collapse that is ignored because the sensors say the bridge is fine.
I've nothing to say here...
I will not be sensored! My rights are on the line here! I can say whatever I want!
/.ers, we must not let sensorship continue. First the MPAA and RIAA are against us and now DARPA. Its time we started speaking out against such sensorship. Now there hypeing "intelligent" sensorship? Since when is sensorship smart?
Fellow
Talk to your congressman or woman and tell them that you don't like sensors. Surely, we can make a change if we all work together.
Now that you've read my post, here's a little note for the dimwitted: it's a joke!

Anybody else try and read this article and not have the faintest idea what it was about?
Doesn't anyone remember the article about the car rental companies monitoring the GPS systems they had installed? Going too fast? Going to Mexico? Going to an anti-anything rally?
When will someone get around to inventing the 'cone of silence' so we can have our privacy back?!
Please mod down.
The sensors sound pretty cool from the article, they mention the military wants to scatter them over a battlefield so they can collect info about where the enemy is, but I wonder how hard it would be for the enemy to just jam the network, or send out a bunch of bogus data into it.
Don't worry... the tinfoil hat you're wearing will keep you from being sensed. All sensors can be fooled... Some systems of sensors are just a little better than others... You just need to know what they measure and send them crappy information.
Clearly, what is needed is some squid on a GSXR-1100 to zip by at some insane speed (which those bikes are quite capable of doing in 1st gear!) and generate enough voltage to blow the sensor out of the ground.
:-)
Throw in a few rare-earth magnets in his pocket and send the whole system into a tizzy.
Oh, what fun we could have....

Yes, people are always calling for laws and regulation before the technology has worked itself out. But tt shouldn't work that way. The technology needs to get its fingers everywhere and become popular before we can think about legal and social issues sensibly. Otherwise we are just speculating wildly and choking off the possibility of genuine innovation. (witness the unfortunate too-early regulation of digital music).
I, for one, am at the same time terrified and excited by the idea of sensors everywhere, communicating wirelessly and powering themselves from ambient heat. I have no idea what kind of applications will come of it, but I don't want any regulation until it's "too late."
First, I've always wondered if cars did indeed emit some type of unique magnetic signature. Because if they did, I would make a sensor to detect the precise signature emitted by the Ford Crown Victoria with the police package, which is drived by the vast majority of police departments in North America (well at least in my state. Add two or three more cars and you got 90% of the police car types.)
:-)
Then I would sell em as police detectors.
Second thought, I'm particularly in love with this
"Omron is about to market a system that lets your car recognize you using your fingerprint."
Since we know that fingerprint devices are not that hard to fool...all ya have to do is dust the car you wanna steal for fingerprints (assuming that the owner of the car has indeed touched their car barehanded at some point in time) and do the elmer's glue thing. I'm excited.
Ok, from the article:
The net is relegated to a small screen and a keyboard. This will detect who you are and where you are.
Is this a Good Thing? I know that it could be used for some very good things, such as instant identity verification, missing & lost persons (the list goes on... I'll spare you) But it seems really, really, really, Big Brotherish, and I'm not so prone to like that very much....
Some new sensors are getting so small--some are invisible to the naked eye--that they will be able to run on 100 microwatts.
Great! So not only can we be watched incessantly, we won't even be able to know IF we're being watched...
At the 100-microwatt level they could gather energy from ambient heat and photovoltaic cells, says Stephen Senturia, a specialist in microsystems at MIT. His colleagues are working on making chips so small that they can power themselves, like watches that need only the kinetic energy generated by movements of the wearer's wrist.
ok, most thought provoking idea in this comment coming right up...
At what point is something sentient and self supporting enough to be considered life? I know that this is relying on a backbone of support, but really, this single feature is actually very interesting if you really think about it. It is capable of sensing it's environment, it's self supporting... has a definate life span... hmmm.. this is really somewhat one the edge of being electronic and creeping towards being alive...
Just my crazy thoughts, but I think this is something we all need to watch carefully, both for the positive aspects of it, and also to be sure (as sure as we can be anyhow) that this is not being used as just another minon of Big Brother... Of course a small amount of Big Brotherism is really quite acceptable, and if used properly this technology could really be a sign of great things to come... I just hope it is used in a way that we would all approve of...
basically hook up two wireless network cameras that would point to the street outside my house.
They would run motion detection software that would basically write to a database when it detected movement. By measuring the time between the two motion captures and knowing the difference in length between the cameras, I could calculate how fast people drive by my house.
By going to my homepage, you would see something like:
Last car went by at: 07:05:30 am
It was going 38.9mph. 3.9 over the speed limit!
Anyways, until the price of wireless network cams come down, I guess it's just a thought.

Along the lines of software license registration when your car takes some type of heavy metal loss, i.e. Heavy rust, part removing yet not debilitating car accidents, etc.. you will have to bring your car to a DOT facility so they can resignature your vehicle. Please note that if the DOT facitility is not your imediate next destination your vehicle will simply stop working. It's good for you; we promise

"...passing vehicles could be identified by their magnetic signatures."
How long before Glock starts making cars?
The world's navies have been identifying ships using magnetic signatures for decades; sophisticated mines exist which can not only distinguish friendly ships from those of the enemy from their magnetic signature, but use a combination of of the acoustic and magnetic signatures of a vessel to identify a particular ship (e.g. to distinguish one Ticonderoga class ship from another). This enables the laying of a minefield that will ignore the signatures of low value units such as minesweepers, frigates and destroyers, and only explode when a particular enemy carrier passes overhead.
One imagines that an intelligence agency wishing to assassinate a foreign president/dictator could achieve similar success using the sensors described in the Forbe's article - they need merely tune the sensors to the signature of the target's limo, and lay them on a public road on the way to his residence.
Hahaha! I am a ghost in their system with my virtually invisible Plastic Pontiac...

Don't worry about being tracked. If you want to mask your car you can keep a small, fluctuating elecrto-magnet in your trunk. Maybe even running a variable current through your can will help.

A number of suburbs of Dallas, Texas (including Carrollton, where I work) are using computerized magnetic sensors to monitor traffic. They're temporary installations -- a box about 4" x 6" x 1" high is placed in the center of the traffic lane, and covered with a thick sheet of what looks to be asphalt-impregnated duct tape.
When they're done with the traffic survey -- 24 hours, typically -- the city engineers cut out the sensor, leaving the tape that was stuck to the ground. You'll see these squares all over town -- they don't seem to disintegrate for several months, even after heavy traffic driving over them. The busiest intersections have several of these leftovers.
A Dallas Morning News article a year or so ago detailed the city's use of the boxes, and noted that they could derive detailed information about the vehicles by their magnetic signatures. I didn't put 2 and 2 together, though, until Slashdot came to the rescue...
Dallas is one of the most insanely vehicle-as-status-symbol regions of the country (according to friends who have lived elsewhere). I thought that Carrollton was simply doing a traffic survey no different than the pneumatic roll-over count... but if you can tell a '82 Chevette from a brand-new Cadillac SUV, it adds a whole new dimension.
Anyone want to bet against the cities prioritizing road repairs based on relative driver income, as opposed to mere number of vehicles?
Stressed? Me? Of course not. Stress is what a rubber band feels before it breaks, silly.
It blocks these sensors. But the Forbes people didn't want to let that out. Tin foil and duct tape are our last best hopes.

How about this: attack an army who is using these things for defence on the eve of their date roll over.
Half way through the attack, the automated defensive guns fall silent, because it is 30000 years before they've been ordered to go active.
To upgrade the defensive guns some poor techie has to wade out there, find them and patch them. Or they have to turn on some kind of remote maintenance program which would allow you to get in, retask them to switch sides and then tell them to start shooting immediately!
Think about it: this is NOT Y2k all over again. These devices are more like land mines than the embedded devices that run powerplants. You place them and forget them, rather than have a maintenence schedule. Keeping them all up to date for future problems would defeat the purpose of an autonomous sensor network!

Seems like you can aler your car's magnetic signature by putting a couple of slabs of sheet metal in the trunk. (Or for that matter... a couple of giant industrial magnets.)

Actually, they *do* use toll tag transponders to track your speed. In Houston, the end result is this cool online map of traffic speeds on all monitored highways in the Houston/Galveston area.
But that data comes from an averaging of individual speeds. Somewhere, there's a computer owned by a government agency which has recorded the fact that Amtech/TransCore tag number 361836456148814 passed station X at 07:32:49.5 and passed station Y (1 mile away) at 07:33:14.2 for an average speed greater than the posted speed limit.
I also remember reading somewhere (possibly on San Antonio's similar site) that any Amtech system can be used to help with their traffic tracking. So their database has you tracked whether you've got a local tag, or one from San Antonio or Dallas, or even your Oklahoma Turnpike Pikepass.
Interesting fact: wrapping your TollTag (etc) in aluminum foil prevents it from being detected by the sensors. That tinfoil beanie doesn't look so silly now, does it?
Stressed? Me? Of course not. Stress is what a rubber band feels before it breaks, silly.

"Sic Semper Tyrannosaurus Rex."
I'm guessing by "identify" they mean something more like counting jeeps vs. trucks vs. tanks.
I think you are correct. The ability to distinguish gross classes of vehicles is much easier than trying to distinguish between models or manufacturers.
Is there any reason to belive that any physical aspect if a single model of car varies enough to be measurable as any sort if identifier?
This research is in a very early stage so this is probably one of the questions they are trying to answer. However, if their system is accurate enough to pick up minute differences in vehicle types like this, it renders them susceptable to mistakes due to slight modifications of the vehicle. A sensor net that is super accurate is likely to not ID a Honda Accord with a big dent in the side as an Accord. And good luck trying to deal with one that has a mountain bike attached to the the roof!
Bottom line is that Automatic Target Recognition (ATR) and Unattended Ground Sensors (UGS) are two technologies which are very much in their early stages. Don't get super worried about the Feds fusing the data from sensors sprinkled all over your hometown to construct a detailed map of your driving habits.

I remember reading some short, asimov i think, where this guy invented this device that canceled all sound waves within like a 10 foot radius.

I talked extensively with a fellow who was maintaining a red light camera. He was very open, and largely responsible for implementing red light cameras in British Columbia.
There are two sensors about four meters apart, one just before and one just after the stop line. These sensors can identify speed and "weight" (magnetic mass) of the vehicle. The magnetic signature is unique to each vehicle model.
In BC, the sensors activate the camera only when the car actually enters the intersection on a red. If you've entered on a yellow, no camera.
Because of the speed-measuring capability, some Vancouver-district municipalities have also really put the screws to the boy-racer fuckups who are street-racing -- speeds like 140kmh through a red light. Ticket for running the red, ticket for reckless driving, ticket for speeding, etc.
Ticket revenue goes directly back to the red light camera operations. The municipalities and government see no money from this system, thereby eliminating any incentive to generate additional revenue by diddling the yellow-light timing and or going all heavy on the marginal cases. The camera supplier doesn't get money, either (and, thus, were of absolutely no use whatsoever when it came time to provide technical support.)
Camera-monitored red lights in BC are showing significant reductions in accidents. Indeed, the savings generated by not paying out claims is proving to be a remarkable value, and insurance companies across North America are starting to realize that spending money on accident reduction will increase their bottom-line profits.
All in all, it's a hella fine system. Our government-tamed insurance monopoly provides us with basic insurance and uninsured driver insurance, plus is mandated to work with municipalities and the RCMP to increase road safety and decrease accident rates. Our public insurer operates in a not-profitable manner: they're not expected to (and are, in fact, expected to not) produce profits.
All our other insurance (liability, collision, whatever else you dream of having) is provided by third-party insurers, so we really get the best of both worlds: a public insurer who's looking out for our basic needs and safety; and private insurers who compete to provide all else.
Sorry this turned into a bit of an insurance/insurer rant, but the public insurer aspect is crucial to the success of our red light camera system, because it eliminates the urge to use the cameras as a profit center instead of a safety tool.
The one thing that keeps popping into my head is how this system can be characterized in its usefullness. Its like a sense for a simple organism.
The implications that are present here produce visions of gathering nodes of information and data not just in the random and simplistic fashions of the internet's present structure, but in the processing fundamental functions of seperate personalities and intelligently focused mini-brains automatically approaching a consciousness as they communicate.
I think the statement made in the article about this "tech being better than the internet" could be accurate, but only when you think on how this could be connected to the internet in some useful way. Where, if the internet is a simple organism, this would be one of its senses - one using the other.

"The hitch: these networks are a snooper's dream come true, putting each citizen in the same situation as that squirrel in the James Reserve. "There would be a whole suite of sensors in a room that could tell you how many people are there and what they are saying. The implications of this are so huge that we need to get sociologists and legal people thinking about this early," says Roger T. Howe, the director of the Sensor &Actuator Center at the University of California at Berkeley."

DARPA has made sensors a top priority, putting up $160 million of its own money and $500 million in matching funds from other U.S. government agencies....the data being sent (video, audio, chemical signature)
But don't worry, top heads are working on the implications.
I'm told that the University of California at Berkely has a copy of 1984 in the library. Someone there might have read about what happens when sensors are so pervasive that it's possible to listen to someone's every word and gesture. Orwell, however, did not imagine intelligent machines such as Carnivore, which could filter "suspicious" paterns and people from the noise. Double plus good purgewise.

They used to have a traffic camera online, but I can't find the link off hand... No affiliation, used to attend classes at the PennState Campus down the road from them.
How many bridges collapsed last year? In the same period, how many electronic gadgets failed? Fail safe is false positive. It won't work till the sensors are monolithic and embeded within the structure itself, such as part of a composite build up layer. I've got little faith in conventional epoxy on steel strain gauges to report anything but false fails. Critters, frost, dew, corrosion and gremlins will break them.
The "Smart Dust" project refered to in another post and the goal of pervasive audio, visual, chemical and other monitoring is a much more disturbing notion, however. Combined with intelligent local filtering, such a network would enable personal tracking and monitoring of all "suspicious" people and conversations. It would be like a giant prison with robot gaurds to keep us all correct. Lierally, no place would be private and there would be no need for the embeded "ID tags" some fools seem to desire.
Friends don't help friends install M$ junk.
There are sensors just like these along various stretches of the border between British Columbia, Canada and Washington, USA where the two nations have parallel streets separated only by a shallow drainage ditch. They are presumably there to detect when cars stop to toss bags of marijuana over the border.

While we were learning about induction, my high school physics teacher talked about a friend he had who worked for a large company who worked on the technology behind the unique magnetic signature detection. It worked very well, and was tested somewhere (I think it was Germany), with very good accuracy. A vehicle could be identified moving throughout the city.
The major drawback to this was that the technology relied on specific patterns formed by the car running over coils under the street (creating inductance). This worked very well if the car's physical makeup didn't change at all, but if someone were to put some scrap iron in the trunk, the unique signature would be changed.
This was actually done quite some time ago, I think in the 1980s. It's pretty cool technology, because the underlying concept is so simple, but it isn't practical in the real world.
Check this.
I guess the novelty is "self-organization" of the data flow over the network itself, but that just feels like buzzword-compliance and military contractor snake-oil to me. And I'm in the military, and recognize snake oil at 30 paces.
But yes, the network traffic will have strong mil-grade encryption, and also have tamper-prevention doohickeys which will destroy all the sensitive and expensive bits if Joe Badguy tries to pull an "all your keys are belong to us".

Wow. Roads that run parallel? And they are expecting people to stop on them? Wonderful. :) Now I know what I have to do in order to retire... Move to BC, get some shady friends, and then build a fairly consistant trebuchet. The trebuchet would be relatively quiet, as would the bags of organic matter hitting the ground. Now the trebuchet would be hard to explain, but that's what the SCA membership would be for.
Has anyone thought about just taking a few old speaker magnets (or the nice ceramic magnets from hard drives) and epoxying them to the frame of the vehicle at various points? Or perhaps in a line running width-wise on the vehicle?
I think it would be safe assumption that this would cause horrible problems for these sensors...

A valid point... but think of this... chaff... invented to fool radar systems of the WWII era was simply strips of metal or some other reflective material. Chaff cost very little compared to radar which cost a very large sum of money, and it severly reduced or eliminated the effectiveness or radar. Simple tact and using countermeasures when crucial is what's important.
There is nothing in the current motes that can not be miniaturized. In three years this demo will be done with a 6" aircraft, and millimeter-scale sensor nodes.

It is really really hard to make a reliable target detection based on a signature from an arbitrary distribution of sensors. The results casually reported in the article were probably achieved after a long period of classifier development and training. The training probably involved passing the exact vehicles that were detected through the sensor array, over and over, with various distributions of sensors. No hard information was reported -- no probability of detection or false alarm rate. We know from earlier slashdot articles on biometrics that pattern recognition systems can be fairly easy to spoof. The mention of fingerprinting and face recognition in the article is especially ironic, since those are the exact approaches that have been shown to be so easy to break. It will probably be awhile before anyone is confident enough to rig a bomb based on an arbitrary sensor array targeted at an untrained vehicle... at least on their own driveway.
You could also probably identify the vehicle by the characteristic radio frequencies given off by the electronics. If not the style, at least the manufacturer and model year.
Then calculate and display its location on the heads-up display on your windshield. But someday vehicles will all be RF tagged anyway... "CowboyNeal's Pinto at 5 o'clock and closing fast."

If you're only collecting occasional data, rather than full scans of everybody, technology's been there for a while. A couple years ago, when San Francisco was going to close the Central Freeway, they spent a week videotaping license plates of cars that took it, had a bunch of convicts at the local prison read the plate numbers, and sent everybody a postcard saying that they were planning to close the freeway and please find an alternate route to work. Did the job just fine.
