People being shown various pictures can have the
resultant
activation of different parts of their brain monitored.
So a picture of a kitten might trigger a certain part of
the
brain for one person, and a different part for another. Po
and 8th of 7 for instance would probably chart
differently
for this
section of the test. (Po, if I'm incorrect in my assumption
that you like kittens, my apologies)
Tracking the subjects reaction and to a series of pictures
would create a unique profile of that person.
To use this, they'd put the helmet on, look into the
viewer
and be shown the slide show. Their brain's reaction to
each
respective picture would be compared to that recorded in
their file and if it matched, then the vault, missile
launch
panel or whatever would open up.
Pictures would be more effective if they were of scenes
or re-enactments from significant events that particular
person's life. For instance, if a clown tried to drag you
away from your parents and kill you at the circus when
you were a kid, a clown picture would be included in
your picture set. Your reaction to that picture would
illicit slightly more terror than the baseline for the
population and this metric would be one of dozens
making up your profile.
So basically a biometric key system that measures your
personality rather than your fingerprints.

Yessss... - although putting your finger on a fingerprint reader is arguably more convenient (and cheaper and quicker) than climbing into an MRI scanner to answer a long list of questions while experts analyse your brainwave patterns. |
|
| |
You can wear a fake fingerprint pretty easily
though. |
|
| |
But I'm not suggesting using these in the checkout
line
at the supermarket to validate your ATM card. This
would be for very critical high security access to
missile silos and stuff. |
|
| |
I think what you'd have is is a kind of half helmet
at the door with the viewer built in that you just
set your head in. Your biometric brain responses
would be automatically compared to those on file,
there wouldn't be any humans involved. It would
probably take about a
minute. |
|
| |
It's not convenient obviously but I think it would
be un-crackable. |
|
| |
//Nothing is uncrackable// |
|
| |
//This would be for very critical high security access to missile silos and stuff.// |
|
| |
So it shows you a picture of a missile, and if you think "Woohoo! That looks like fun!" it lets you in? |
|
| |
If that's what your original profile showed you'd
think, yea. |
|
| |
That being said, I'd propose this technology be used
for screening as well. If the person's sexual centers
get activated by the sight of a mushroom cloud, he
probably shouldn't be trusted with anything more
dangerous than a butter knife. |
|
| |
There speaks a man who clearly has absolutely no idea of just how dangerous, indeed lethal, a butter knife can be in the wrong hands. |
|
| |
Sometimes the best weapon is the one that doesn't look
like a weapon. |
|
| |
Sometimes the best lock is one that doesn't look like a
lock. [+], even though I doubt it would work. |
|
| |
Not necessarily. Put a butter knife in the wrong hands and
before you know it that sucker's jammed in a light socket,
the wall is on fire, the sprinklers are flooding the house,
your insurance adjusters are dusting off their abaci, and
somewhere, for entirely unrelated reasons, Kevin Bacon is
eating a live puppy. Thus, a butter knife in the wrong
hands can be at least as destructive and lethal as one in
the right hands. |

During the Cold War, the US invested staggering amounts of money in a system of "permissive links" for release of nuclear weapons, involving multiple redundant interlocked systems, both electronic and mechanical. These were designed to prevent nuclear weapons being used without permission. |
|
| |
The British system was slightly different. |
|
| |
The British system involved nuclear weapons being armed by the use of the sort of small circular key often found on gambling machines and bicycle locks. The keyswitch had two positions, "Armed", and "Disarmed". |
|
| |
On RAF bases, the keys were kept by the Senior Warrant Officer Armourer, officially in a safe, but more often than not in his trouser pocket. |
|
| |
In the event of a nuclear strike being called, the Base Commander would order the Armourer to go and arm the nuclear weapons. |
|
| |
The failsafe procedure was that, if the Armourer thought that something was amiss, like the Base Commander had lost his marbles, then he would ring up his opposite number on another base and ask, "Hey up mate, is this Bikini Red business pukka, or what ?". |
|
| |
If the reply was negative, then he wouldn't arm the weapons, but would probably drop the keys down the nearest street drain, just to be on the safe side. |
|
| |
The system was simple, cheap, and 100% effective. |
|
| |
"The more complex a technology, the smaller the error needed to defeat it." |
|
| |
Well, if there's one thing you can trust the Brits to do right,
it's... |
|
| |
Wait, no, you can't trust them at all. My mistake. |
|
| |
//100% effective// What's the denominator in that
calculation, [8th]? |
|
| |
As for the idea itself: What technology did you have
in mind for measuring brain activation, [Dr R.]? |
|
| |
I think they have real time MRI technology. Might be
able to get some useful info by simply measuring
localized electrical activity in the brain with
external electrodes. |
|
| |
'They' do indeed have real-time MRI, by which I mean it
exists. My mom occasionally gets to use one when she does
locum tenens work at the Fort Leonard Wood base hospital. |
|
| |
Kevin Bacon can never be entirely unrelated. |
|
| |
[Dr. R.] Since it's speculative, anyway, whether the
measurements would be either distinctive, or
consistent enough for this application, I like the EEG
idea better. For military application, you could
require missileers to keep their heads shaved. |

"Good morning, I'm [mouseposture], and I'll be your obligatory tonsurist for today. Please, just put the keys down and step away from the console ..." |

Would take too long! also emotional response must
vary as well, because one some days i cry watching
wall-e and other days i don't give a crap about
anything. |
|
| |
// i cry watching wall-e // |
|
| |
You think that's a tear-jerker ? Try Silent Running ... |
|
| |
Ah, that's good old 70s dystopian family fun. I, too,
wondered about variations based on mood, level of
anxiety, cosmic radiation, what Jim had for breakfast, etc. |
|
| |
// i cry watching wall-e // |
|
| |
It's not emotional.... I just react poorly to pepper-spray. |
|
| |
Give it time. Eventually, he'll be unable to enjoy
himself *without* pepper spray. |
|
| |
Ah, yes, illustrating in classic form the difference between
a kink and a fetish. |
|
| |
Most likely you will encounter problems with context. Even slightly differing images, even if the content is presumed similar, will ellicit responses from dissimilar neural paths. |
|
| |
Also, there is a significant chance of false positives that fingerprints, for example, will not give you. |
|
| |
My very limited understanding is that just as our thoughts
are in a constant state of change, so too are our brains.
Dunno if that effects brainwave scans. |
|

I forgot to mention Blade Runner. WIGTTISIAMWIBNIIWR. |

I seem to remember this exact debate happening on this exact web-site in the past. I'm not thinking this is De ja vu, either.... more like prior art. |
