The U.S. Transportation Security Agency (TSA)
is currently testing an on-site biometric-response-based lie-detector system called the Cogito device
) at an airport in Knoxville, Tennessee. If adopted, the Cogito1002, made by Israeli company Suspect Detection Systems Ltd. (SDS)
, will augment a human-based screening system called SPOT (Screening Passengers by Observation Technique), which first began testing at Logan Airport (Boston) after 9/11 and is now operational in approx. a dozen U.S. airports.
Here’s how the Cogito1002 tech works:…
A passenger goes into an oval booth, swipes their passport, dons a set of headphones, and sticks their hand inside a sensor that monitors biometric responses (blood pressure, heart rate/pulse, and sweat levels) while they answer 15-20 questions in their language of choice on a touch screen about their travel plans. The person’s sex, age, and nationality, as well as their location, determine what questions get asked, and the whole process takes approx. 5 minutes.
According to an article
in the The Wall Street Journal (WSJ)
, Shabtai Shoval, CEO of Suspect Detection Systems developed the Cogito1002
with the assistance of “leading former Israeli intelligence officials, polygraph experts and computer-science academics.” The device goes beyond the scope of a standard lie detector machine by analyzing a person’s answers not only in relation to the rest of his/her answers, but also those of his/her peer group that’s been previously determined by security experts. "We can recognize patterns for people with hostile agendas based on research with Palestinians, Israelis, Americans and other nationalities in Israel," Mr. Shoval says. "We haven’t tried it with Chinese or Iraqis yet." The Cogito 1002
can be customized for specific cultures and specific threats based on the intelligence that’s been gleaned.
In tests conducted inside Israel, the Cogito1002
is showing an approx. 85% accuracy rate with control groups role-acting as terrorists. Not bad, however 15% is still too many terrorists getting through, which is why auxilliary terrorist-detection systems, including human/people-based systems like SPOT, are so important. It should be noted that the Cogito1002 also incorrectly identified 8% of innocent passengers as potential threats in the Israeli tests. SDS wants to up the Cogito1002’s
accuracy level/rate (i.e. correct terrorist detection level/rate) to 90%, while reducing the false positives (identifying innocent travelers as potential threats) to only 4%. That’s the goal, anyway. Let’s all hope they’re successful and the system works as advertised. If they are, and it does, chalk another one up for the Israelis.
Just one more thing. It’s Defense Review’s opinion as of this writing that the Cogito1002 should not be used on every airport traveler. It’s our opinion that it should only be used on those subjects that have been previously identified on-site (or even earlier) by human observers or other human-intelligence methods/procedures as fitting specific preditermined potential-threat profiles or exhibiting suspicious behavior. Otherwise, the system (Cogito1002) could create unnecessary delays at airports and incorrectly red-flag more innocent people than otherwise necessary. On the other hand, even if the machine clears an individual, that should not necessarily be the last word, as machines can be sometimes be fooled. If an individual fits the predetermined terrorist profile and/or is acting suspiciously, human-based screening techniques by trained professionals should always be incorporated into the security package. At this point in time, there is simply no substitute (mechanical, electronic, or any other type) for human intuition and educated opinion, especially that of trained anti-terrorism/security professionals.
