Smart Cams Said To Be Able To Spot Criminals By How They Walk

They record our every move from almost every vantage point. But soon CCTV cameras will have another power: the ability to predict crime on Britain's streets.

Researchers at Sussex University have discovered how CCTV camera controllers spot criminals by studying the way they walk.

The team of psychologists studied 10,000 excerpts from CCTV footage and found a number of 'trigger signals' in criminal behavior which showed when offenders were about to commit a crime.

The footage showed how car thieves tended to walk erratically and look in directions irrelevant to their path of travel. Before an act of violence culprits would walk aggressively, their arms static by their sides, taking long purposeful strides.

Professor Tom Troscianko of the School of Cognitive and Computer Sciences, who headed the study, said researchers chose a hundred scenes from CCTV footage filmed around the country. Each scene lasted 15 seconds and they were based around three scenarios: a fight outside a public venue, violence against property in the street, and car theft in an underground car park. Some scenes depicted the moments prior to a crime while others showed activity that did not result in a crime.

A hundred people - 50 professional CCTV controllers and 50 civilian volunteers - were asked to watch the footage and guess which scene would result in a crime and indicate when during the 15 seconds they had reached their decision.

'The actual crime was never shown' said Troscianko. 'In each sequence we recorded the exact movements of the people. We looked at the moments in each sequence which increased the chance of people making the right prediction that a crime would happen.'

The types of behavior were then ranked. 'When these trigger factors were present, like a type of walk or a type of "gaze behavior", we saw that people were approximately twice as likely to predict a crime' said Troscianko.

Before a violent act like a fight, an assailant walked in a very aggressive way. 'The stride length and speed of walk would increase, but they would not run. Their arms did not move much, and tended to stay down at their sides. They walk in a direct line purposefully.' Similar patterns were observed before damage was done to property.

Before a car theft a culprit would walk slowly or even remain still while looking around. 'He will be looking to see if he is being observed.'

The team are now seeking funding to develop software to continue their work. But campaigners have expressed concern at a new breed of 'intelligent cameras' raising concerns of a Big Brother society.

MP Simon Hughes, the Liberal Democrats' home affairs spokesman said: 'CCTV needs to be used as the exception and not the rule in public places and only rarely in private places.'

CHINA TO SHARE IN U.S. FIRM'S FACE-READING TECHNOLOGY

Dee Ann Divis
UNITED PRESS INTERNATIONAL

-----------------------------------------------------------

The company that supplied controversial face-recognition technology to scan people on the streets of Tampa, Fla., is
working with commercial partners in China to supply the same technology there.

Face-recognition software analyzes the spaces and angles of as many as 80 key points on a person's face. Data from only 14 to 20 such points are enough to create a unique digital "face print" that can then be compared with an existing
database of face prints, derived, for example, from pictures of wanted criminals.

When used with surveillance cameras, the monitoring system can scan the faces in a store, on a street or at a sporting
event for those wanted by the police. Such a system was used at this year's Super Bowl to scan for criminals and possible terrorists. Tampa has since used the system in a popular nightlife district.

Joseph Atick, chairman and CEO of Visionics Corp. and an inventor of face-recognition technology, told reporters
Wednesday that his company is doing business in roughly 50 to 60 nations, including China. One application being
considered for China is access control, he said, citing banking as an example.

One's face becomes one's password, which could be especially useful where not all account holders are literate.

There was no technology transfer involved in the Chinese transactions, Mr. Atick said. "They buy basically a finished
product from us, just like they would buy a piece of equipment and integrate it into their applications," he said.

The company would not sell to Iraq, Libya or Iran, Mr. Atick said. The revelation about the possible sale of such systems to China came during a news conference sponsored by the Security Industry Association.

The face-recognition system has been used in Mexico to prevent voter fraud. In Newham, a neighborhood in London,
incidents of crime have dropped by 40 percent since the system was installed two years ago, Mr. Atick said.

Privacy advocates in the United States have raised alarms over face recognition and other surveillance systems, such
as closed-circuit television. The industry association is calling for a refocusing on developing policies to govern
the responsible use of face-recognition and closed-circuit television.

SIA would prefer voluntary rules and distributed internally developed guidelines on the use of closed-circuit television. The document suggested it be used only for public safety and law enforcement, and not be used for monitoring programs based on race, sex, national origin, sexual orientation or disability.

It also suggested that public systems be set up to see only what a police officer on site would see and that tapes be
erased after an appropriate amount of time.

Not everyone is convinced of the usefulness of such guidelines.

There are guidelines against spying, giving out classified information and rifling Internal Revenue Service records --
which have not stopped abuses, said Richard Diamond, spokesman for House Majority Leader Dick Armey, Texas
Republican, who has come out strongly against surveillance technologies.

Industry representatives countered that such technologies aid police in their duties and could help stop identity
theft. They also asserted that such monitoring in public places does not infringe on protections against unreasonable
search and seizure because courts have ruled there is no expectation of privacy in the public places where such
systems are used.

["I think the industry's getting very nervous," Marc Rottenber, executive director of the Electronic Privacy Information Center, told Reuters news agency. "I rather suspect the stuff they're emphasizing, a lot of that is to protect business interests."]

Though no law appears to ban closed-circuit television or face recognition, regulation may indeed be on the horizon.
Hearings are planned for when Congress returns in September, Mr. Diamond said.

"The point is this technology is too powerful and too open to abuse, and guidelines aren't going to fix that problem,"
he said.

You may be spied on - for Australia's wellbeing

March 7, 2002

Sydney Morning Herald-Australia

Australia's top-secret satellite spy agency has been given sweeping new powers to report on Australians to the Federal Government.

New rules governing the work of the Defense Signals Directorate were quietly introduced during last year's election campaign by the outgoing defense minister, Peter Reith.

The old rules explicitly prohibited the deliberate interception of communications between Australians in Australia - but the new rules, and the legislation under which they are made, do not.

Further, the new rules allow the DSD to report to the Government on Australians if their activities affect national security, foreign relations and even the country's economic wellbeing. Previously, DSD was only allowed to report on Australians where their activities involved threats to a person's safety or involvement in serious crime.

News of Mr. Reith's move to expand DSD's powers comes amid scrutiny of the agency's role in the Tampa affair.

The formal role of the DSD is to intercept foreign satellite and phone communications in the region for intelligence purposes, not the communications of Australians. But allegations emerged last month that DSD intercepted calls to and from the Norwegian ship MV Tampa, including with the Maritime Union of Australia. The Government later denied DSD had reported to it on communications "from" the MUA.

But the matter is now the subject of an inquiry by the Inspector General of Intelligence Services.

During questioning from Labor's defense spokesman, Chris Evans, at estimates committee hearings last month, DSD officials refused to release the rules governing Australians' privacy at the time of the Tampa crisis - on the basis that they were classified documents.

The new rules, formulated by Mr. Reith on October 29, say they may now report on Australians where their involvement is already public knowledge or where the person is "a representative of the Commonwealth or of a state or territory in the normal course of official duties".

DSD may report on Australians if deleting reference to them would reduce the usefulness of reports related to "maintaining Australia's national security; maintaining Australia's economic wellbeing; promoting Australia's foreign relations; preventing or investigating the commission of a serious crime; responding to an apparent threat to the safety of a person; responding to a serious risk to an Australian intelligence operation or operative; or ... relates to an Australian person who is acting for, or on behalf of, or is suspected acting for, or on behalf of, a foreign power".

The rules add that "a person within Australia shall be presumed to be an Australian person; and a person outside Australia shall be presumed to be a non-Australian person", subject to other evidence of nationality.

Last night, Senator Evans said the new rules raised questions not only about Australians' privacy but about what directions DSD was given during the Tampa affair.

Civil libertarians have already expressed fears about proposals to expand the powers of the domestic spy agency, ASIO.

Net Monitoring Scheme Under Fire

BBC NEWS
Monday, 4 March, 2002, 20:01 GMT


Plans to archive internet data gets thumbs down

UK Government plans to archive all internet traffic and e-mail has been singled out for a controversial award at this year's Big Brother Award ceremony.
The awards - established in 1998 by Human Rights watchdog Privacy International - are designed to expose the state erosions of privacy as well as honoring those that made an outstanding contribution to preserving privacy.

The plan to store all communication data won in the Most Appalling Project category.

The scheme was the brainchild of the National Criminal Intelligence Service and is outlined in the government's Anti-Terrorism Act.

'Worst act yet'

Other "winners" included Cabinet Secretary Sir Richard Wilson who was singled out for what the judges described as "his long-standing commitment to opposing freedom of information, data protection and ministerial accountability".

The Lifetime Menace award went to another government scheme: the plan to introduce nationwide ID cards. The proposal, long mooted in government, is for a comprehensive data-sharing scheme between government agencies and the private sector.


Golden boot is given to award winners

The judges described the scheme as the worst threat to privacy yet.

Plans by the Department for Education and Skills for creating a student-tracking system won it the award for Most Heinous Government Organization.

Insurance firm the Norwich Union won the Most Invasive Organization Award, in part for its satellite vehicle-tracking project.

Speaking at the ceremony at the London School of Economics, head of Privacy International, Simon Davies, said the erosion of privacy, often using technology, alarmed him.

Technology beyond law

"During the judging process, it has become clear that government agencies and companies have stooped to an all-time low in the willful violation of our privacy.

"We have been almost overwhelmed this year by a flood of new entries, many of which involve technologies and techniques that are beyond the control of law, and outside of the comprehension of policy makers."

On a more optimistic note, five "Winstons" were also handed out to organizations or individuals who the judges believed had made an outstanding contribution to the protection of privacy and human rights.

German Greens MEP Ilka Schroder was honored for her part in the investigation of the American spying system Echelon. Thanks in part to her work, the system is being investigated by the European Parliament.

Guess Who's Tracking You By Cell Phone?

By Ben Charny
Special to ZDNet News
February 27, 2002, 3:00 PM PT


The nation's cell phone service providers will soon know exactly where every one of their customers is, at all times, and privacy rights groups are asking what they plan to do with the information.
All U.S. carriers are under Federal Communications Commission orders to make it possible for police to locate cell phones calling 911, something police can't do now. Carriers plan to use the same systems to sell services like helping stranded motorists even if they don't know their location, or finding the closest restaurant.

Because people with cell phone generally always carry their phone with them, the FCC regulations give the thriving market for personal information something its never had a chance to get: the exact locations at all times of more than 140 million people.

"There are some things you don't mind other people knowing, but your location isn't one of them," said Gary Laden, a privacy program director for BBBOnline, a Better Business Bureau subsidiary.

Private details that become public knowledge every time people visit Web pages and leave information, every address that the U.S. government sells, or every ATM transaction that dutifully records the time are just some of the ways that technology has been tracking individuals. But knowing someone's location at all times adds a significant new twist to tracking information about people.

Sprint is already offering an Enhanced 911 (E911) system in Rhode Island and sells a pair of phones that work on the system. In a year, Verizon Wireless says nearly half of all new handsets activated will have this capability. The FCC expects 95 percent of the cell phones sold in the United States by 2005 will meet the FCC guidelines.

Neither AT&T Wireless nor Verizon Wireless offer any E911 or related services yet. But both say they do not sell the information they already collect from their subscribers, such as a home address used to send a monthly bill. And they don't plan to do anything different with the location information once they do offer those services.

"We already know where you live, but we haven't made that available to anyone," Verizon Wireless representative Nancy Stark said.

Travis Larson, a spokesman for the wireless trade group Cellular Telecommunications and Internet Association said the worry isn't so much the carriers, but the independent companies that provide the commercial services.

"Not all companies in this space will be CTIA members," he said. "Then you have a group of businesses unregulated."

So far, backers of two consumer privacy initiatives say they've begun talks with carriers about what they plan to do with the information they collect.

On Wednesday, AT&T Wireless spokesman Ritch Blasi said the company is the first U.S. carrier to have its privacy policies reviewed and approved by Truste, a coalition that approves online privacy policies, whose sponsors include AT&T Wireless, AOL Time Warner, Intel, Microsoft and others.

Truste and AT&T Wireless are also working together to create a uniform policy for what carriers should do with the information they collect. Blasi and a spokesman for Truste said they want carriers to tell subscribers that their location can be tracked, and what plans, if any, they have for the information.

Also Wednesday, supporters of a recently approved privacy standard known as P3P (Platform for Privacy Preferences) say they've also begun a dialogue with wireless carriers.

Some versions of Microsoft's Internet Explorer use P3P to automate the process of deciding if a Web site's privacy policies are good enough for a user. People can pre-load their Web browsers with preferences, such as whether they want a Web site to accept a browser's cookies filled with personal information. If the browser is directed toward a Web page, it'll seek out the privacy policies and determine if they match the preferred ones. If not, the Web page doesn't load.

Josh Freed, a spokesman for the Internet Education Foundation, said backers of P3P want to offer the same type of function to cell phone customers. "This way, every time there is an exchange of data, the phone alerts you if there is a conflict," he said.

The effort is very new, Freed and others warn, and is preceding even the existing technology.

"We have a blank page in front of us now," said J. Walter Hyer, AT&T Wireless chief privacy officer.

U.S. to Weigh Computer Chip Implant

Wednesday, Feb. 27, 2002 AP

WASHINGTON (AP) - A Florida technology company is poised to ask the government for permission to market a first-ever computer ID chip that could be embedded beneath a person's skin.

For airports, nuclear power plants and other high security facilities, the immediate benefits could be a closer-to-foolproof security system. But privacy advocates warn the chip could lead to encroachments on civil liberties.

The implant technology is another case of science fiction evolving into fact. Those who have long advanced the idea of implant chips say it could someday mean no more easy-to-counterfeit ID cards nor dozing security guards.

Just a computer chip - about the size of a grain of rice - that would be difficult to remove and tough to mimic.

Other uses of the technology on the horizon, from an added device that would allow satellite tracking of an individual's every movement to the storage of sensitive data like medical records, are already attracting interest across the globe for tasks like foiling kidnappings or assisting paramedics.

Applied Digital Solutions' new ``VeriChip'' is another sign that Sept. 11 has catapulted the science of security into a realm with uncharted possibilities - and also new fears for privacy.

``The problem is that you always have to think about what the device will be used for tomorrow,'' said Lee Tien, a senior attorney for the Electronic Frontier Foundation, a privacy advocacy group.

``It's what we call function creep. At first a device is used for applications we all agree are good but then it slowly is used for more than it was intended,'' he said.

Applied Digital, based in Palm Beach, Fla., says it will soon begin the process of getting Food and Drug Administration approval for the device, and intends to limit its marketing to companies that ensure its human use is voluntary.

``The line in the sand that we draw is that the use of the VeriChip would always be voluntarily,'' said Keith Bolton, chief technology officer and a vice president at Applied Digital. ``We would never provide it to a company that intended to coerce people to use it.''

More than a decade ago, Applied bought a competing firm, Destron Fearing, which had been making chips implanted in animals for several years. Those chips were mainly bought by animal owners wanting to provide another way for pound workers to identify a lost pet.

Chips for humans aren't that much different.

But the company was hesitant to market them for people because of ethical questions. The devastation of Sept. 11 solidified the company's resolve to market the human chip and brought about a new sensibility about the possible interest.

``It's a sad time ... when people have to wonder whether it's safe in their own country,'' Bolton said.

The makers of the chip also foresee it being used to help emergency workers diagnose a lost Alzheimer's patient or access an unconscious patient's medical history.

Getting the implant would go something like this:

A person or company buys the chip from Applied Digital for about $200 and the company encodes it with the desired information. The person seeking the implant takes the tiny device - about the size of a grain of rice, to their doctor, who can insert it with a large needle device.

The doctor monitors the device for several weeks to make sure it doesn't move and that no infection develops.

The device has no power supply, rather it contains a millimeter-long magnetic coil that is activated when a scanning device is run across the skin above it. A tiny transmitter on the chip sends out the data.

Without a scanner, the chip cannot be read. Applied Digital plans to give away chip readers to hospitals and ambulance companies, in the hopes they'll become standard equipment.

The chip has drawn attention from several religious groups.

Theologian and author Terry Cook said he worries the identification chip could be the ``mark of the beast,'' an identifying mark that all people will be forced to wear just before the end times, according to the Bible.

Applied Digital has consulted theologians and appeared on the religious television program the ``700 Club'' to assure viewers the chip didn't fit the biblical description of the mark because it is under the skin and hidden from view.

Even with the privacy and religious concerns, some are already eager to use the product.

Jeff Jacobs in Coral Springs, Florida has contacted the company in hopes of becoming the first person to purchase the chip.

Jacobs suffers from a number of serious allergies and wants to make sure medical personnel can diagnose him.

``They would know who to contact, they would know what medications I'm on, and it's quite a few,'' he said. ``They would know what I'm allergic to, what kind of operations I've had and where there might be problems.''

Applied Digital says technology to let the chip to be used for tracking is already well under development.

Eight Latin American companies have contacted Applied Digital and have openly encouraged the company to pursue the internal tracking devices. In some countries, kidnapping has become an epidemic that limits tourism and business.

Laser-armed Humvee to blast mines

 19:00 10 July 02

Exclusive from New Scientist Print Edition

 An armoured car fitted with powerful laser beam designed to blast landmines and cluster bomblets from the battlefield will shortly begin testing at an army proving ground near Waynesville, Missouri.

 

Zeus fires its laser thunderbolt

Zeus fires its laser thunderbolt

The US Army is developing the laser-based de-mining method, dubbed Zeus, as a way of clearing mines left on airfields and roads during battles or by retreating enemy forces. The trials will be the first chance for the Army's de-mining experts to see if the technique works as planned.

The idea is to clear the numerous devices that modern warfare leaves strewn around on the ground. Small mines are often scattered from helicopters and trucks, and cluster bombs spray out hundreds of smaller bomblets, many of which fail to explode on impact.

"When dropped on soft ground, you can get dud rates of 30 per cent," says Owen Hofer of Sparta, the firm based in Huntsville, Alabama, that is developing Zeus for the Army.


Green beam

The laser is mounted in a turret on top of one of the Army's all-purpose armoured "Humvees". A soldier sitting at a console inside the jeep uses a joystick to point a low-power green laser beam at the target.

They then switch on a more powerful solid-state infrared laser of the type used for industrial cutting and welding, which delivers between 500 and 2000 watts through the same optical system as the green targeting beam.

When the beam strikes a mine, the heat burns off the explosive or detonates it. Sparta says its own tests on dummy munitions show Zeus should work on mines with metal or plastic cases, as well as unexploded artillery shells and bombs.

It reckons the laser will be able to destroy landmines and bomblets from between 25 and 250 metres away. Laser beams cannot penetrate soil, so it won't work against buried mines.


Total clearance

One of the challenges of building Zeus is preventing it from overheating. Industrial lasers are usually cooled by a continuous flow of water, but that luxury is not available on the battlefield, so Sparta has had to develop a closed-cycle cooling system.

But however well Zeus serves the military, it is unlikely to meet the needs of civilian de-mining organisations, says Harry Thomas of the humanitarian de-mining programme at Warwick University. De-mining during military action is a very different business from clearing up after a conflict, he says.

The laser would doubtless miss some mines, and while armies expect casualties, civilian farmers do not. They want their land cleared completely. And even if it cleared all surface mines, that would still leave buried mines or others that had become covered by dust, sand or vegetation.
