Can Computers Detect Suspicious Behavior?
from the minority-report dept
The arrest earlier this week of most-wanted criminal Warren Steed Jeffs, was a successful use of behavioral profiling. The cops who pulled over the car with Jeffs in it didn't recognize him, but they suspected they had someone big due to his visibly pulsating carotid artery. Upon seeing that, they summoned backup, and eventually realized who they had pulled over. But the problem with this type of security is that it doesn't scale very well. One-on-one encounters are costly and time intensive, and it's difficult to train people in effective behavioral profiling. A group of scientists in Australia are now trying to develop algorithms that recognize suspicious behavior. For example, the computer might be able to identify if someone deliberately left a briefcase unattended, or if that person had an expression of nervousness as they shoved it beneath a chair. The technology hopes to improve on useless facial recognition techniques, which only work with known suspects, and tend to overwhelm security forces with false positives. Sadly, in all likelihood, this new approach, apart from being several years off, would likely run into many of the same problems.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Since, it technically isn't illegal to "act suspicious". I can see kids trying to fake suspicious behaviour for laughs and giggle.

And i'm sure there are the same laws in the USA.

Hit it on the head
But at least it's a step forward. Hopefully, we'll get those cool Star Trek computers that will hold a conversation and be able to interpret what you want it to do.
Like I always say, it'll be a great day when my computer does what I want it to do, not what I tell it to do.

NOW WHAT
in fact, it may get to the point of trained terrorists ot career criminals using chemicals to paralyze their faces before commencing an act
People are nevous if they have some guillt or fear - mind control may now be taught to them

Of course we already have a working example
What conclusions? Take a typical exchange with one of my (UK) card issuers (after I've called them back on a known good number):
Bank: "We've suspended your Visa card because we've detected a suspicious pattern of transactions."
Me: "Do tell."
Bank: "It's been used repeatedly in...AMERICA!"
Me: "And do you know what type of card it is dear?"
Bank: "Oh yes. It's an American Airlines affinity card."
Me: "Does that fact not give you a clue...?"
In other words, I'd be very, very worried about an unacceptably high rate of false positives, not to mention the very real risks arising from false negatives, once people downgrade other security measures due to blind faith in the all-knowing expert system.

However, without the sunglass wearing, pistol carrying cop, there would be no "pulsing cartoid". A man who feels he's escaping without detection acts much different than someone under the close scrutiny of a Law Enforcement Officer.
