Well, the eyeball thing worked in "Demolition Man", and we all know how much research goes into big budget action films with Sylvester Stallone, Wesley Snipes, and Sandra Bullock...

On the iris-scanning note, it's already been put into use at a local elementary school. Check it out.

As far as whether one could accurately reproduce the effect required by an iris scanner with a non-connected ocular....well, it depends upon what time the eye was extracted.

After about 72 hours, give or take, the eye color begins to fade. The process can be sped up or slowed down depending on a number of variables. But the characterstics is rarely, if ever, the same.

As far as faking fingerprints goes...first, making a sheet thin enough so that your own skil oils would pass would also allow your own fingerprints to pass through. It's just not technologically possible.

Also, if I were utilizing someone else's fingerprints, I would not want to leave one bit of myself behind (skil oils included).

On the other hand, for faking fingerprints, cornstartch does wonders. But you didn't hear it from me.

Interesting. I assume that you could make a fake eye with the same pattern as the subject, too. In both cases, though, the scanners which measure pupil dilation would not unlock.

Okay, I see your point. The print would show the real pattern under the fake pattern. You'd need the fake prints to be as thick as a pair of dishwashing gloves.

Yes, on reflection I think you're right. I have no idea if you can get DNA from skin oil, but even if not, it would probably be carrying skin cells, too. For that matter, I am neglecting to take into account that anyone using the fake fingerprints would otherwise be leaving behind their own fiber, hair and skin cells, too. The alternative is to go in wearing a clean suit - a bit conspicuous.

How does that work?


C alias(the show) on 3/30/5 ? - the eyeball trick was done, by the computer guy, put in the field while hdqtrs was on lockdown. He shot a really really very very bad guy on accident, while trying to put his hightech gun together without letting this real bad guy watching him know it. the bad guy died at once, but they still needed his eye to get to a data base. had to use a 'spork' spoon-fork to get the eyeball out intact. (yuck)not(yuckyuck?)... firsttimethroughhere, hope you're for good somehow somewhere. Shalom.
