Surveillance Society: New High-Tech Cameras Are Watching You

In the era of computer-controlled surveillance, your every move could be captured by cameras, whether you're shopping in the grocery store or driving on the freeway. Proponents say it will keep us safe, but at what cost?

The ferry arrived, the gangway went down and 7-year-old Emma Powell rushed toward the Statue of Liberty. She climbed onto the grass around the star-shaped foundation. She put on a green foam crown with seven protruding rays. Turning so that her body was oriented just like Lady Liberty's, Emma extended her right arm skyward with an imaginary torch. I snapped a picture. Then I took my niece's hand, and we went off to buy some pretzels.

Other people were taking pictures, too, and not just the other tourists—Liberty Island, name notwithstanding, is one of the most heavily surveilled places in America. Dozens of cameras record hundreds of hours of video daily, a volume that strains the monitoring capability of guards. The National Park Service has enlisted extra help, and as Emma and I strolled around, we weren't just being watched by people. We were being watched by machines.

Liberty Island's video cameras all feed into a computer system. The park doesn't disclose details, but fully equipped, the system is capable of running software that analyzes the imagery and automatically alerts human overseers to any suspicious events. The software can spot when somebody abandons a bag or backpack. It has the ability to discern between ferryboats, which are allowed to approach the island, and private vessels, which are not. And it can count bodies, detecting if somebody is trying to stay on the island after closing, or assessing when people are grouped too tightly together, which might indicate a fight or gang activity. "A camera with artificial intelligence can be there 24/7, doesn't need a bathroom break, doesn't need a lunch break and doesn't go on vacation," says Ian Ehrenberg, former vice president of Nice Systems, the program's developer.

Most Americans would probably welcome such technology at what clearly is a marquee terrorist target. An ABC News/Washington Post poll in July 2007 found that 71 percent of Americans favor increased video surveillance. What people may not realize, however, is that advanced monitoring systems such as the one at the Statue of Liberty are proliferating around the country. High-profile national security efforts make the news—wiretapping phone conversations, Internet monitoring—but state-of-the-art surveillance is increasingly being used in more every-day settings. By local police and businesses. In banks, schools and stores. There are an estimated 30 million surveillance cameras now deployed in the United States shooting 4 billion hours of footage a week. Americans are being watched, all of us, almost everywhere.

We have arrived at a unique moment in the history of surveillance. The price of both megapixels and gigabytes has plummeted, making it possible to collect a previously unimaginable quantity and quality of data. Advances in processing power and software, meanwhile, are beginning to allow computers to surmount the greatest limitation of traditional surveillance—the ability of eyeballs to effectively observe the activity on dozens of video screens simultaneously. Computers can't do all the work by themselves, but they can expand the capabilities of humans exponentially.

Security expert Bruce Schneier says that it is naive to think that we can stop these technological advances, especially as they become more affordable and are hard-wired into everyday businesses. (I know of a local pizzeria that warns customers with a posted sign: "Stop stealing the spice shakers! We know who you are, we have 24-hour surveillance!") But it is also reckless to let the advances proceed without a discussion of safeguards against privacy abuses. "Society is fundamentally changing and we aren't having a conversation about it," Schneier says. "We are entering the era of wholesale surveillance."

A Face in the Crowd Used by banks, hotels and retail stores, 3VR’s “searchable surveillance” systems automatically create a template of every face that passes in front of security cameras (it caught our author here at a Chicago hotel check-in counter). The system creates a mathematical model based on the geometry of each person’s face that can be compared to a central list of known suspects for instant alerts. The technology can also automatically log events based on an automated object recognition analysis of an entire scene—for example, Frank Jones met with Doris Meeker at 12:45 pm; Meeker arrived in a blue sedan. Because all events are cataloged, several months’ worth of data can be analyzed in minutes.

Earlier this year, on a hot summer afternoon, I left my Brooklyn apartment to do some shoplifting.

I cruised the aisles of the neighborhood grocery store, a Pathmark, tossing items into my cart like a normal shopper would—Frosted Mini-Wheats, Pledge Wipes, a bag of carrots. Then I put them on the belt at checkout. My secret was on the lower level of the cart: a 12-pack of beer, concealed and undetectable. Or so I thought. Midway through checkout the cashier addressed me, no malice in her voice, but no doubt either. "Do you want to ring up that beer?"

My heist had been condoned by Pedro Ramos, Pathmark's vice president of loss prevention, though he didn't know precisely when or where I was going to attempt it. The beer was identified by an object-recognition scanner at ankle level—a LaneHawk, manufactured by Evolution Robotics—which prompted the cashier's question. Overhead, a camera recorded the incident and an alert was triggered in Ramos's office miles away on Staten Island. He immediately pulled up digital video and later relayed what he saw. "You concealed a 12-pack of Coronas on the bottom of the cart by strategically placing newspaper circulars so as to obstruct the view of the cashier."

Pathmark uses StoreVision, a powerful video analytic and data-mining system. There are as many as 120 cameras in some stores, and employees with high-level security clearances can log on via the Web and see what any one of them is recording in real time. An executive on vacation in Brussels could spy on the frozen-food aisle in Brooklyn.

In 2006 theft and fraud cost American stores $41.6 billion, an all-time high. Employee theft accounted for nearly half of the total (shoplifting was only a third), so much of the surveillance aims to catch in-house crooks. If the cashier had given me the beer for free—employees often work with an outside accomplice—the system would know by automatically comparing what the video recorded with what the register logged. The technologies employed by Pathmark don't stop crime but they make a dent; weekly losses are reduced by an average of 15 percent.

Pathmark archives every transaction of every customer, and the grocery chain is hardly alone. Amazon knows what you read; Netflix, your taste in movies. Search engines such as Google and Yahoo retain your queries for months, and can identify searches by IP address—sometimes by individual computer. Many corporations log your every transaction with a stated goal of reducing fraud and improving marketing efforts. Until fairly recently it was impractical to retain all this data. But now the low cost of digital storage—you can get a terabyte hard drive for less than $350—makes nearly limitless archiving possible.

So what's the problem? "The concern is that information collected for one purpose is used for something entirely different down the road," says Ari Schwartz, deputy director of the Center for Democracy and Technology, a Washington, D.C., think tank.

This may sound like a privacy wonk's paranoia. But examples abound. Take E-ZPass. Drivers signed up for the system to speed up toll collection. But 11 states now supply E-ZPass records—when and where a toll was paid, and by whom—in response to court orders in criminal cases. Seven of those states provide information in civil cases such as divorce, proving, for instance, that a husband who claimed he was at a meeting in Pennsylvania was actually heading to his lover's house in New Jersey. (New York divorce lawyer Jacalyn Barnett has called E-ZPass the "easy way to show you took the offramp to adultery.")

On a case-by-case basis, the collection of surveillance footage and customer data is usually justifiable and benign. But the totality of information being amassed combined with the relatively fluid flow of that data can be troubling. Corporations often share what they know about customers with government agencies and vice versa. AT&T, for example, is being sued by the Electronic Frontier Foundation, a San Francisco-based civil liberties group, for allowing the National Security Agency almost unlimited access to monitor customers' e-mails, phone calls and Internet browsing activity.

"We are heading toward a total surveillance society in which your every move, your every transaction, is duly registered and recorded by some computer," says Jay Stanley, a privacy expert with the American Civil Liberties Union.

Clean Plate Club License-plate readers from companies such as Remington-Elsag use high-intensity infrared cameras that are mounted on the outside of police patrol cars (or even helicopters) or set up in static locations. On patrol cars, the system operates independ-ently while the officer drives, automatically checking plates from up to four lanes of traffic against an on-board “hot list” of wanted vehicles. It uses optical character recognition to differentiate letters and digits from background noise such as images and grime. It reads up to 900 plates per minute from up to 50 ft. away with greater than 95 percent accuracy.

In the late 18th century, English philosopher Jeremy Bentham dreamed up a new type of prison: the panopticon. It would be built so that guards could see all of the prisoners at all times without their knowing they were being watched, creating "the sentiment of an invisible omniscience," Bentham wrote. America is starting to resemble a giant panopticon, according to surveillance critics like Bob Barr, a former Republican congressman from Georgia. "Were Bentham alive today, he probably would be the most sought-after consultant on the planet," he recently wrote in a Washington Times op-ed.

One of the most popular new technologies in law enforcement is the license-plate reader, or LPR. The leading manufacturer is Remington-Elsag, based in Madison, N.C. Its Mobile Plate Hunter 900 consists of cameras mounted on the outside of a squad car and connected to a computer database in the vehicle. The plate hunter employs optical-character-recognition technology originally developed for high-speed mail sorting. LPRs automate the process of "running a plate" to check if a vehicle is stolen or if the driver has any outstanding warrants. The sensors work whether the police car is parked or doing 75 mph. An officer working the old-fashioned way might check a couple dozen plates a shift. The LPR can check 10,000.

New York's Long Beach Police Department is one of more than 200 agencies around the country that use LPRs, and I rode in a squad car with Sgt. Bill Dodge to see the technology at work. A computer screen mounted in front of the glovebox flashed black-and-white images of every photographed plate; low alarms, like the sounds of your character dying in an '80s video game, droned for the problem cars. Over the course of a couple of hours we didn't net any car thieves or kidnappers, but Dodge's LPR identified dozens of cars with suspended or revoked registrations. He said that the system doesn't violate anyone's privacy—"there's no magic technology that lets it see inside a garage"—and praised its fairness. "It doesn't matter if you're black, white, old, young, a man or a woman, the system cannot discriminate. It looks at everyone and everything."

In July, New York City officials unveiled the Lower Manhattan Security Initiative, modeled after London's "Ring of Steel," which will include license-plate readers, automated roadblocks and 3000 new surveillance cameras—adding to the 250 already in place. Chicago, meanwhile, which has 560 anti-crime cameras deployed on city streets, revealed plans in September to add a sophisticated IBM video analytic system that would automatically detect abandoned bags, suspicious behaviors (such as a vehicle repeatedly circling the Sears Tower) and vehicles sought by the police. Expanded surveillance is perhaps to be expected for these high-profile cities, but they're hardly alone. Richmond, Calif.; Spokane, Wash.; and Greenville, N.C., are among the cities that have recently announced plans to add electronic spying eyes. According to iSuppli, a market research firm, the global surveillance-camera business is expected to grow from $4.9 billion in 2006 to $9 billion in 2011.

The ability of cameras to deter criminals is unproven, but their value in helping to solve crimes is not. Recall how videos led to several arrests in the July 7, 2005, London subway bombings. The problem with surveillance video is that there's simply too much of it. "It's impossible for mere mortals with eyeballs and brains to process all the information we're gathering," says Stephen Russell, the chief executive of 3VR, a company that makes video analytic software.

An investigator looking for a particular piece of video is like a researcher working in a library with a jumbled card catalog—or in books with no tables of contents. The solution of 3VR and other similar companies is software that automatically analyzes and tags video contents, from the colors and locations of cars to the characteristics of individual faces that pass before the lens. The goal is to allow rapid digital search; instead of functioning like a shoddy library, 3VR hopes to be "the Google of surveillance video," Russell says. "It took 1000 [British agents] six weeks to review all the video after July 7. Had 3VRs been in place, it might have taken a dozen or so agents a weekend," he claims.

I recently spent a night at Chicago's Talbott Hotel, a luxurious small retreat where the staff addresses you by name and you have to clear a dozen pillows from the cushy king-size bed before lying down. The Talbott is surveilled by 70 cameras, which cover every public area of the hotel and feed into a 3VR system.

Troy Strand, general manager of the hotel, showed me a computer screen divided into 16 panes with different camera views. He looked up my check-in time and seconds later retrieved video of my arrival the previous day. There I was, towing my carry-on toward room 1504.

Strand found a few other shots showing me, then instructed the software to begin facial analysis. The system assessed the balance of light and dark areas of skin tone and hair and gauged the distance between my eyes, nose and mouth. Strand instructed the system to search for all recorded videos showing my face, and the computer retrieved several dozen faces, none of which was mine. There was a woman and a black man. But Strand went through a few pages of results, and I started to show up. When he clicked on any image, an associated video of me played—crossing the lobby to go to breakfast, chatting with the front-desk clerk.

So-called "facial profiling" has been surveillance's next big thing for nearly a decade, and it is only now showing tentative signs of feasibility. It's easy to see why people are seduced by the promise of this technology. Twelve bank companies employ 3VR systems at numerous locations, which build a facial template for every single person that enters any branch. If somebody cashes a check that is later determined to be stolen, the person's face can be flagged in the system, and the next time the con artist comes in, the system is supposed to alert the tellers.

For Strand, the security system's fancier features are just a bonus. The cameras are in plain sight, so he believes that would-be criminals and misbehaving employees are deterred. "You can't have security people on every floor monitoring every angle of the building," he says.

There's a man in Salt Lake City who knows what I did last summer. Specifically, he knows what I did on Aug. 24, 2007. He knows that I checked my EarthLink e-mail at 1:25 pm, and then blew a half an hour on ESPN's Web site. He also knows that my wife, Anne, wanted new shoes, from Hush Puppies or DSW, and that she synced her electronic planner—"she has quite a busy schedule," the man noted—and downloaded some podcasts. We both printed out passes for free weeklong trials at 24 Hour Fitness, but instead of working out, apparently spent the evening watching a pay-per-view movie. It was Bridge to Terabithia or Zodiac, he thinks.

The man's name is Joe Wilkinson, and he works for Raytheon Oakley Systems. The company specializes in "insider risk management," which means dealing with the problem of employees who, whether through innocent accident or nefarious plot, do things they really shouldn't be doing at work. Oakley's software, developed for the U.S. government and now used by ten Fortune 100 companies, monitors computer use remotely and invisibly. Wilkinson had agreed to run a surveillance trial with me as the subject, and after accessing my computer via the Web, he installed an "agent" that regularly reported my activities back to him.

The modern desktop machine is a multimedia distraction monster: friend, lover, shopping mall, stereo, television, movie theater and adult video store are mere mouse clicks away. Raytheon Oakley's software caught me wasting valuable work time checking personal e-mails and reading digital camera reviews online. Companies are also concerned about hostile work environments caused by employees openly surfing porn in the office—conse-quently, my 10:14 am visit to a risqué site was duly noted. Employees also leak trade secrets. (Consider the case of DuPont chemist Gary Min, who, after accepting a job with a competitor in 2005, raided DuPont's electronic library for $400 million worth of technical documents. He was caught by the FBI last year.) If I had downloaded any large engineering drawings onto a removable hard drive, Oakley's software would have alerted Wilkinson. And employees bad-mouth the boss. I wrote an e-mail to Anne that mentioned my editor at Popular Mechanics, Glenn Derene. Wilkinson rigged the software to flag anything with Derene's name, and alarm bells rang. Sorry, Glenn.

Surveillance of this sort is common. A 2005 survey by the American Management Association and the ePolicy Institute found that 36 percent of companies monitor workers on a keystroke-by-keystroke basis; 55 percent review e-mail messages, and 76 percent monitor Web sites visited. "Total Behavioral Visibility" is Raytheon Oakley's motto. The vice president of marketing, Tom Bennett, knows that some people fear workplace monitoring. But the technology has many positive aspects. "We are not Big Brother," he insists.

Employees are sometimes lazy or dishonest, but often they're simply careless. A parent who has to leave the office at midday to care for a sick child might copy sensitive company information onto a USB drive so that he can work at home. An account manager might carelessly send customer credit card numbers over an unsecured wireless network where they can be stolen. Bennett says that his company's software helps companies understand and improve how workers use their computers. The Oakley monitoring application works like a TiVo, allowing an instant video replay: where you pointed the mouse, when you clicked, what you wrote. This can catch the guilty but also exonerate the innocent, because the replay puts your actions in context.

Crowd Control At government facilities, city centers, retail shops, airports and public landmarks, there are simply too many people for security guards to watch all at once. But cameras connected to analytic software can pay attention to hundreds, even thousands, of people at a time. Behavioral analysis programs from companies such as Nice Systems can learn “normal” human patterns in a location—in an airport queue, for instance, people may move from left to right—highlighting and logging behaviors of individuals who move or act in unusual ways. The system can adjust as the pattern of human behavior changes—the line now moves from right to left—and then call attention to behavior that deviates from the new “normal.”

The debate over surveillance pits the tangible benefits of saving lives and dollars against the abstract ones of preserving privacy and freedom. To many people, the promise of increased security is worth the exchange. History shows that new technologies, once developed, are seldom abandoned, and the computer vision systems being adopted today are transforming America from a society that spies upon a small number of suspicious individuals to one that monitors everybody. The question arises: Do people exercise their perfectly legal freedoms as freely when they know they're being watched? As the ACLU's Stanley argues, "You need space in your life to live beyond the gaze of society."

Surveillance has become pervasive. It is also more enduring. As companies develop powerful archiving and search tools, your life will be accessible for years to come in rich multimedia records. The information about you may be collected for reasonable purposes—but as its life span increases, so too does the chance that it may fall into unscrupulous hands.

Several months after I stayed at the Talbott Hotel, Derene, my editor, called Troy Strand to ask if he still had the security camera images of me at the hotel. He did. My niece Emma's Statue of Liberty shots are probably stored on a computer, as are the records of all my Pathmark purchases. Ramos could query my shopping trip of, say, Jan. 13, 2005, and replay video keyed precisely to any part of the register tape—from the fifth item scanned, pork chops, to the tenth, broccoli. That's innocuous and even humorous on the surface, but the more I thought about the store's power, the more it disturbed me.

I took the bottle back

I would've taken the bottle back - empty...after all, you paid for the wine/

But seriously, this is insane.

I've been joking to my kids (I'm now a great-gramma) that I'm going to go back up the north woods where I was born - far from any big cities, highways, etc...

But everyday, it looks more and more inviting. And wear a long-billed cap when you go near un-civililzation.

Jed Lacey (and his friends) would be proud.....
Drake does Orwell several times greater.

As does Dr David Wood

and David Brin (The Transparent Society)

Others include:
Daniel Dinello (tech books)
Richard Linklater (film)

We all fear mass surveillance, but as the article pnts up, with some kind of AI (a very good AI, mind you) you are no more likely to run afoul of it as you would running a stop sign with the cop on the corner.

In these systems, the ‘human in the loop’ is alway the limiting factor.

And the ‘human in the loop’ is also the most frighting part of the system.

Looks like an interesting article, bmflr.

According to Intrade, the winner of the December 12th GOP debate was... Duncan Hunter.

They don’t mean it like that. The reality of the situation is that in our modern day world the average person probably makes at least a dozen data points a day. That’s 300 million people times 12 data points times 365 days a year which equals an absurd quantity of data. It’s not little brains that can’t comprehend greatness, it’s terabytes being piled upon terabytes being piled upon terabytes, just plain not human processable quantities of data.

We need to spend some time thinking about disguises. Big hats, big glasses with colored lenses, high, turned up collars to hunch down into, wigs, padded clothing, etc.

Sounds like a very comfortable way to go out, doesn't it---especially in a place as hot as Texas--LOL!

Seriously, the cameras are a fact of life, nowdays. It's up to us to figure out a way around them.

In these systems, the ‘human in the loop’ is alway the limiting factor. And the ‘human in the loop’ is also the most frighting part of the system.

Bingo. Thank you for pointing this out. I was beginning to find the rest of the responses to this article highly irritating.

It breaks my heart to see my fellow conservatives opposing the development of technology, crying that the technology itself is evil and oppressive. These are people who clearly understand that a gun is merely a tool for the commission of either evil or good, depending on who is wielding it. These are people who recognize that it is not box-cutters or shampoo bottles that hijack airplanes, it's terrorists who hijack airplanes. Yet you tell these people that we have developed machines that enable individuals to rapidly acquire and collate massive amounts of information, and these people freak out about the machines rather than the individuals doing the collating.

David Brin does an excellent job in "Transparent Society" of describing a civilization that uses the prolific distribution of publicly accessible surveillance cameras for security, commerce, productivity, and personal enrichment, while still being a free, open society. In fact, in David Brin's model, the cameras enable the general public to keep tighter tabs on the police force than any society heretofore seen in the real world.

There is not, and never has been, anything to fear from technology itself. Fundamental to the principles of American government is the recognition that our government officials and their delegates are all human beings, just like you and me, and any tool that can empower them can also empower us.
