MALVERN, England (Reuters)
...This is no real security alarm: it's a demonstration at the British technology group QinetiQ of a scanning device that sees under people's clothes to spot not just metal but other potential threats like ceramic knives or hidden drugs.
The electromagnetic technology, known as Millimeter Wave (MMW), is just one aspect of a potential revolution in security screening being pioneered at QinetiQ, formerly part of the research arm of the British defense ministry.
...the trend for the future will be to move the scanners outside the terminal building and operate them in "stand-off mode" -- checking people from a distance before they even set foot inside.
The advantage is obvious: to spot potential attackers without alerting them to the fact, and gain precious seconds for security forces to prevent an attack.
Another prospect in store for air travelers is "hyperspectral sensing" that will check for chemicals called pheromones, secreted by the human body, which may indicate agitation or stress.
"People under stress tend to exude slightly different pheromones, and you can pick this up ... There are sensing techniques we're working on," Stringer said.
The stress may have an innocent cause, such as fear of flying, but could also betray the nervousness of a potential attacker. The point is to alert security staff to something unusual that may need further investigation.
As with MMW, the technology could function at a distance and without the need for people to wait in line. By conducting such checks while people are approaching the airport and moving through it, authorities could avoid bottlenecks and queues.
As the passenger proceeds through the terminal, the next layer of surveillance could be carried out through "cognitive software" which monitors his or her movements and sounds a silent alarm if it picks up an unusual pattern.
"Someone who's been back in and out of the same place three times or keeps bumping into the same people might be something that's worthy of further investigation ... I think that's really the sort of capabilities we're going to be looking at," Stringer said in an interview.
Stringer says the potential market for MMW runs into the hundreds of millions of dollars and goes well beyond the transport sector.
"We're spending quite a lot of time talking to multinationals who want to establish perimeter security systems around plant, installations and buildings," he said.
QinetiQ -- owned 30 percent by private equity group Carlyle and 56 percent by the British government -- expects rapid growth for its security business as it gears up for a stock market launch.
But how will ordinary people embrace the prospect of surveillance technology that sees through their clothes, checks how much they're sweating and tracks their airport wanderings between the tax-free shops and the toilets?
Stringer acknowledges that some might see this as George Orwell's Big Brother come true. "There are always going to be issues of privacy here and they're not to be belittled, they're important."
But he says smarter technology will actually make the checks less intrusive than those now in standard practice, such as being searched head to foot after setting off a metal detector alarm.

That is some good work on some good, real stuff. God I love reality. Whatever that means...
