Shadow Analysis Could Spot Terrorists

kdawson posted more than 5 years ago | from the made-in-the-shade dept.

Privacy 245

Hugh Pickens writes "An engineer at Jet Propulsion Labs says it should be possible to identify people from the way they walk — a technique called gait analysis, whose power lies in the fact that a person's walking style is very hard to disguise. Adrian Stoica has written software that recognizes human movement in aerial and satellite video footage by isolating moving shadows and using data on the time of day and the camera angle to correct shadows that are elongated or foreshortened. In tests on footage shot from the sixth floor of a building, Stoica says his software was indeed able to extract useful gait data. Extending the idea to satellites could prove trickier, though. Space imaging expert Bhupendra Jasani at King's College London says geostationary satellites simply don't have the resolution to provide useful detail. 'I find it hard to believe they could apply this technique from space,' says Jasani." Comments on the article speculate on the maximum resolution possible from KH-11 and KH-12 spy satellites.

Aye, well the Scots have them all beat:

University of West Scotland research reveals that a woman's gait may reveal her orgasmic ability. [physorg.com] - A new study found that trained sexologists could infer a woman's history of vaginal orgasm by observing the way she walks. The study is published in the September 2008 issue of The Journal of Sexual Medicine, the official journal of the International Society for Sexual Medicine and the International Society for the Study of Women's Sexual Health.

Combine that with satellite-based shadow analysis, and... Giggity!

How does it account for any type of foot, ankle, or leg injury that doesn't require crutches?

How about someone throwing a handful of rocks in the shoe to forcibly change their gait?

How about someone that is conscientious enough to change their gait at every new location?

When I'm tired (after running miles) or carring heavy bags I walk differently. Sometimes I even sometimes realise I'm not walking 'normally' when I'm going along the corridor at work. Either I am a perambulatory schizophrenic (and will end up in Gitmo for impersonating a terrorist) or this is all just nonsense.

Although I do know that my running style is pretty constant (I have running shoes fit for my gait), but I can walk with varying purpose and my gait matches that.

Re:Upon deployment.... (2, Insightful)

houghi (78078) | more than 5 years ago | (#24886865)

Well, what you do is put everybody in a database and if they do not find you in that database, you must have something to hide and thus are a terrerist.
This is just one more parameter to let less terrerists slip through the mazes of the net.

Only once the non-negatives of that list are equal to the amount of people in the world will we be completely safe from terrerists. (Or so they want you to believe)

Yes, but that still doesn't answer his questions (4, Insightful)

Moraelin (679338) | more than 5 years ago | (#24887225)

Yes, but that still doesn't answer his objections.

Let's say you've got nothing to hide, are on the database, then you get an abcess in your foot. I had one, for example, thanks to some retarded shoes which did that much damage and it got infected. Next thing I knew, my walking style could belong in a "ministry of funny walks" sketch, except for me it was more painful than funny.

Would I suddenly be outside the database, and thus a suspect, in that scenario? Or what if they entered a criminal in the database when he had a similar injury, and then I have a similar injury two years later and suddenly I look like the re-appearance of Abdallah ibn Jihad, wanted for arson, genocide and jay-walking in East Bumfuckistan and Elbonia? (Made up name, btw. Means IIRC slave of Allah, son of jihad, or enough to get your average anti-terrrist spook get his panties in a knot by itself.)

It's not like you can choose when you'll have such an injury.

What is the degree of confidence in such an identification, anyway? How fine you can slice a gait and still leave room for normal daily variations? (E.g., account for stuff like today I'm feeling chippy and walk a lot livelier, while yesterday was a shitty day and my walk probably reflected that. E.g., today I walk on grass in the woods, yesterday I was walking on wet concrete, and a month ago I was walking on sand at the beach.) As they say, "if you're one in a million, there are 6000 exactly like you." Will it be able to positively identify said Abdallah ibn Jihad, even when he's walking uphill through the snow with a pebble in his boot, or will it be more like "it's one of 6000 people, one of which is Abdallah ibn Jihad"? Again, that's the number if it could positively and unerringly distinguish between one million different gaits.

How about? How about? How about? You see, America already won. We have forced the terrorists to change their walking lifestyle. Now, perhaps if Osama were to stumble down a Pakastani cliff and break his leg because of the limestone padding in his sandals, that would be a plus, right. We'd never even have to fire a shot.

The Nirvana fallacy is the logical error of comparing actual things with unrealistic, idealized alternatives. It can also refer to the tendency to assume that there is a perfect solution to a particular problem.

By creating a false dichotomy that presents one choice which is obviously advantageous--while at the same time being completely implausible--a person using the nirvana fallacy can attack any opposing idea (reformed social welfare programs, for example) because it is imperfect. The choice is not between real world solutions and utopia; it is, rather, a choice between one realistic possibility and another which is merely better.

An example of the nirvana fallacy would be opposing a policy that reduces poverty because it does not completely eliminate poverty.

Also, what control does this give the gov't? To make you walk funny? "Better that a thousand terrorists go freely about their bloody business than for one free person to have a recorded gait"?

While we're at it, we should remove all the wire taps we're using against the mafia and gangs, 'cause we're violating their privacy. They should be able to conduct their business without the prying eyes and ears of big brother.

They aren't claiming that "all terrorists walk like this." They're claiming that an individual's gait is very unique and can be used like a fingerprint, DNA, or facial recognition to identify an individual. And apparently it is possible to use arial photography to extract useful gait information from the shadows on the ground. So, theoretically, you could use a spy satellite with high enough resolution to track an individual virtually anywhere (outdoors) on the planet. So they could input gait information about a known terrorist and then track their movements world-wide.

Now, whether this is actually good or practical is an entirely different discussion... But it certainly sounds like it could possibly be useful.

Geostationary? (4, Insightful)

geostationary satellites simply don't have the resolution to provide useful detail

Who puts a spysat in geostationary orbit? It's way too high, you'd need a telescope that dwarfs Hubble to get a decent view. You put spysats in the lowest orbit you can get away with, and you make sure that you have enough of them that any target of interest will be covered frequently enough for your purposes.

Yea, geostationary orbit [wikipedia.org] is about 22,000 miles up where as Low Earth Orbit [wikipedia.org] can be as low as 160 miles. The solution is to deploy multiple spy satellites so you can always cover an area.

Re:Geostationary? (3, Interesting)

raddan (519638) | more than 5 years ago | (#24886841)

It still doesn't matter. It's speculated that the finest resolution a spy satellite can get is in the 5-10cm range, and that's probably using many digital imaging tricks. TFA doesn't say what kind of resolution the software requires, but I doubt that 5-10cm is fine enough-- when I walk, there's probably, what, 2-3cm of bounce in my step?

Still, this is clever idea. Attention conspiracy theorists: make sure to walk outside only at noontime. At the equator.

The spy agencies probably fell for the same tricks as consumers at Best Buy. The sticker on the demo satellite said:

Store even more spy shots with twice the onboard storage! With a breathtaking 5-10cm zoom**, you won't miss a single detail!

**Included SurveillanceMaster® imaging program provides maximum software zoom of 5-10cm. Actual maximum optical zoom: 30cm.

Re:Geostationary? (5, Interesting)

mencomenco (551866) | more than 5 years ago | (#24887223)

5-10 cm is 1985 resolution, dude. About the time they got bought by Bournes (now Recon/Optical, Inc.), engineers from Chicago Aerial Industries were bragging at MIT meetings in Chicago that we'd never know the resolution of the Keyhole series. Recon, the successor to Chicago Aerial Industries now HQ'd in Virginia, has dominated the industry ever since CAI cameras detected Soviet missiles in Cuba in October, 1962.

And from the same sources, the original Hubble "mirror flaw" occured because they shipped a Keyhole part by mistake. Not hard to believe since they built both systems. Left unsaid was how similar the Hubble/Keyhole airframes were.

23 years later, after spending gadzillion bucks inventing & perfecting adaptive/active optics and instant digital signal processing we certainly are being observed even more closely.

I am thinking there is more to this gait analaysis than watching the shadow of your legs. Think of your whole body and how it moves. Think about your arm movements, your head movement and your greater body movement, things that don't change easily with bulky clothes. Does your send you slightly side to side, do you keep one foot on front of the other...there are a lot of factors in this and I imagine the very smart people who came up with this already thought about the very things Slashdotters are suggesting here.

The problem with gait recognition is, AFIAK, it's not really been proven to be a decent biometric - i.e. I'm not sure it's really all that unique, not without measuring things at a very high resolution, which probably isn't going to be possible either from space or with the current install-base of cctv cams.

A LOT of energy is being squandered in attempts to keep US in the dark. in the end (give or take a few 1000 years), the creators will prevail (world without end, etc...), as it has always been. the process of gaining yOUR release from the current hostage situation may not be what you might think it is. butt of course, most of US don't know, or care what a precarious/fatal situation we're in. for example; the insidious attempts by the felonious corepirate nazi execrable to block the suns' light, interfering with a requirement (sunlight) for us to stay healthy/alive. it's likely not good for yOUR health/memories 'else they'd be bragging about it? we're intending for the whoreabully deceptive (they'll do ANYTHING for a bit more monIE/power) felons to give up/fail even further, in attempting to control the 'weather', as well as a # of other things/events.

dictator style micro management has never worked (for very long). it's an illness. tie that with life0cidal aggression & softwar gangster style bullying, & what do we have? a greed/fear/ego based recipe for disaster. meanwhile, you can help to stop the bleeding (loss of life & limb);

http://www.cnn.com/2007/POLITICS/12/28/vermont.banning.bush.ap/index.html

the bleeding must be stopped before any healing can begin. jailing a couple of corepirate nazi hired goons would send a clear message to the rest of the world from US. any truthful look at the 'scorecard' would reveal that we are a society in decline/deep doo-doo, despite all of the scriptdead pr ?firm? generated drum beating & flag waving propaganda that we are constantly bombarded with. is it time to get real yet? please consider carefully ALL of yOUR other 'options'. the creators will prevail. as it has always been.

corepirate nazi execrable costs outweigh benefits
(Score:-)mynuts won, the king is a fink)
by ourselves on everyday 24/7

as there are no benefits, just more&more death/debt & disruption. fortunately there's an 'army' of light bringers, coming yOUR way. the little ones/innocents must/will be protected. after the big flash, ALL of yOUR imaginary 'borders' may blur a bit? for each of the creators' innocents harmed in any way, there is a debt that must/will be repaid by you/us, as the perpetrators/minions of unprecedented evile, will not be available. 'vote' with (what's left in) yOUR wallet, & by your behaviors. help bring an end to unprecedented evile's manifestation through yOUR owned felonious corepirate nazi glowbull warmongering execrable. some of US should consider ourselves somewhat fortunate to be among those scheduled to survive after the big flash/implementation of the creators' wwwildly popular planet/population rescue initiative/mandate. it's right in the manual, 'world without end', etc.... as we all ?know?, change is inevitable, & denying/ignoring gravity, logic, morality, etc..., is only possible, on a temporary basis. concern about the course of events that will occur should the life0cidal execrable fail to be intervened upon is in order. 'do not be dismayed' (also from the manual). however, it's ok/recommended, to not attempt to live under/accept, fauxking nazi felon greed/fear/ego based pr ?firm? scriptdead mindphuking hypenosys.

consult with/trust in yOUR creators. providing more than enough of everything for everyone (without any distracting/spiritdead personal gain motives), whilst badtolling unprecedented evile, using an unlimited supply of newclear power, since/until forever. see you there?

"If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."

meanwhile, the life0cidal philistines continue on their path of death, debt, & disruption for most of US. gov. bush denies health care for the little ones;

I'm a bit duck-footed, and about anybody can recognize who I am before they're close enough to see my face. I'd probably have trouble fooling a human; if I held up a liquor store or a bank, a mask wouldn't help.

But a computer? Who do these people think they're fooling? Computers are brain-dead simple to fool about anything whatever.

As to resolution, well, this comes from my memory of a a newspaper article so take it with a grain of salt, but when Hubble was launched it was reported that if you put in in St Louis you could read the date on a dime in De Moines if it was focused properly. If they can aim Hubble up, they could aim another one down. Does anyboy have verification/rebuttal to this? I'm curious; as I said, I read it in the paper and they;re bad about getting science and technology wrong.

Wonderful euphemism (5, Insightful)

Anonymous Coward | more than 5 years ago | (#24886809)

I like how yet again ``spotting terrorists'' is an euphemism for ``spotting everyone else, too''. I habitually substitute ``spotting YOU'' and honestly think of all the good it would do.

Yes, there's useful stuff in there, but again only if those watching you can be trusted. This has been said often enough before and still people score cheap headlines with the same fallacy.

So... um, you've got a "terrorist" under tight enough surveillance that you can build a "gait profile", but you're not arresting or just outright executing them?

Admittedly, I support this effort. Once complete, the DHS can take its rightful place as the Ministry of Funny Names and Walks.

Now your identity?

Study says [physorg.com] gait may be associated with orgasmic ability. Specifically they indicate something like an 80% success rate of identifying women who have vaginal orgasms based on their gait. There certainly seems to be something to the biomechanical structure of your body. I honestly wonder if its a unique fingerprint or if an entire family my be very similar.

It was 30 years ago, or so, that i saw pictures taken from an orbiting satellite that peered down to a golf course. The final enlarged image was that of the golf-ball. I shall never forget what it displayed: " Titleist " !! And i suspect, after 30 years and trillions of dollars, that the capabilities are improved, to put it mildly!!!!!!!

Why use a satellite? (0)

Anonymous Coward | more than 5 years ago | (#24887099)

A small aircraft manned or unmanned can do the same thing more cheaply and from much lower altitude, which also gets around atmospheric distortions.

As for disguising gait, I guess you can fool all the spy cameras some of the time and some of the spy cameras all of the time, but ...

Still don't you get a comforting glow knowing how well we are being "looked after" (evil cackle).

Incorrect summary (2, Interesting)

fermion (181285) | more than 5 years ago | (#24887255)

Shadow analysis could spot known terrorist, if we know who there are, and if we have sufficient information on them. That is nothing new. We can often spot terrorist if we know enough about them. Of course, we actually have to have the ability and desire to go to the caves where they are hiding and apprehend them.

But the real issue is that to stop terrorism we have know before hand the people that pose a real and credible threat. And I am not talking about the people with video cameras who are going to prove the police force is lying in statements or beating people up. I am talking about knowing that Timothy McVeigh is going to kill almost 200 people, including children. Or that Eric Rudolf was going to mount a extended reign of terror killing a innocent woman and a police officer. How does the gait analysis going to save the babies that the next religious extremist is going to kill?

nimbius (983462) | more than 5 years ago | (#24887379)

on new technology designed to determine whether we're all terrorists, i think back to the days when phrenology could determine whether we were all murderers.

to consider someone a terrorist based on their perceived actions is to, in a sense, insist upon the fact that all elements of emotion and kinematics are objective in human nature. discordians buck this trend, so do most sysadmins, libertarians, drug users, and anyone with a mental disorder.

without further adieu, an exploit for this system: before planning a terrorist attack, wear a shoe 1 size too large, or place something uncomfortable like a pebble in it. really, anything to alter your gait should take care of it.

Re:everytime i see these articles (1)

bsDaemon (87307) | more than 5 years ago | (#24887495)

Yes, but discordians, sysadmins, libertarians, drug users and those with mental disorders are only slightly less unpopular than terrorists, and many people think that they are on the same level.

Just put a full-leg cast or brace on, and your gait will change without you even trying.

SableTek (963685) | more than 5 years ago | (#24887475)

The original post implies we should alert both Disney, in order to protect Peter Pan, and The Shadow [wikipedia.org] . As others have noted, if one has enough information to analyze the gait, shadow, etc. of an individual, even via satellite, then one most likely has the ability to arrest said individual. I am both amused and frightened that such a thing as 'shadow analysis' or 'gait analysis' is even remotely considered scientific. The scientific 'proof' that one's gait cannot be altered is 'thin' at best, as actors and con artists have been doing so for years.
