The cognitive fingerprint would not work when I was tired or not feeling well, and if microsoft had anything to do with it, it would not work at all. The problem of this concept, as with all similar concepts, is that the key record must reside someplace, and that place is not secure, and can't be secure. Likewise the fingerprint and eye exam systems. Each is a fair deterent but none is invinceable. A password with pauses in the cadence could be quite secure until hackers figured out how to record keyboard entry cadence.
A far better system is to only have "trustworthy" people in the area, and to mandate that sensitive material never leave the secure area. Yes, that would indeed be quite inconvenient. But staying secure is almost always inconvenient. Oh Well!
Say someone gets your p/w and accesses your computer...but doesn't use it like you usually do- too hesitant, maybe typing much faster or slower, something. The operating system recognizes that there's an issue. It challenges you to further identify yourself, and if "you" can't it locks down again. Maybe to a tighter level. A system like that might actually be, as they say, a good thing.
This is a very interesting concept and one that would throw hackers a curve as the technology develops.
I think this will start out like voice recognition technology... llimted and a little rough around the edges. However, as time progresses and more sophisticated algorithms are employed, I think this will become a valuable security option.
This DARPA technology reminds me of the Context Awarness research being conducted by MIT's Media Lab where the computer can recognize the user's emotional behavior patterns and adjust automatically their work environment. Hackers will definitely find this method of security intriguing to crack.
That's a pretty interesting development, although I would think from a security standpoint, there are tradeoffs. Isn't it easier to mimic someone's gestures and writing style than to somehow clone their biometrics identity? In any regard, pretty cool stuff and if nothing else, the science behind the cognitive fingerprint could have great application in a host of areas.
