Doubts over passport face scans

[DukeP]

Well. Actually it doesnt matter what part of you you insert. Just make sure to have it spun into a gazillion pieces, sliced with the right enzymes and concentrated into a past before you apply it.


But THEN its fast.

Then somehow I don't see it beeing widely used soon...problems with either "can't be sure the blood belongs to the one" or "problematic and/or costly desinfection" (OTOH...I could imagine something similar in the concept to the things used to puncture a finger for sugar blood level: put a finger here, BAM! (one use needle, automatically replaced in the innards of the machine), air stream or such gets you blood and automatic machanism lholds/lifts your finger so that you won't leave blood. But I'm afraid it would require coopoeration, and some would be afraid of pain )

Or perhaps some amount of...thing (don't have time to check dictionary) in your mouth is enough? (assuming you haven't eaton cow or pork )

[DukeP]

As is, its only usable by the most determined scientists.

But it DOES in theory take ANY piece of you that carries DNA - your feces, hair, nails, skin etc.

As to how it WILL eventually work?
I really dont think that GATTICA is that far off the mark. DO watch that movie, if at all possible!!

~~DukeP~~

[Nowhere]

Blah, currently, and for some time to come, it's practically impossible for me to watch ANY movie

Sort of...it's complicated...

[DukeP]

Well.

Can You watch DivX?

I could make a DivX recompression at a resolution of 128x72. It should be small enough to fit in any pocket..


Seriously - whats up?

~~DukeP~~

[Nowhere]

Uhmm...overall serious life complications. It's useless to say more.

Perhaps I should stop posting...perhaps that's just a runaway (not that I can do anything about...things)

[DukeP]

Eeeeww.

Best of luck sorting everything out.

Im certain that we all will be there for you, if you need to chat.

Hang in there.

It's too late to sort it out...nuff said.

(plaese, no cheering/comforting: I know the situation and can do it many times better than you - but it won't change reality)

[Dr Mordrid]

In terms of the sample used a body fluid like saliva is best as it already has loose cells in suspension. Solid or semisolid things like hair etc. are more problematic as they need more in the way of fractioning.

I'd bet that eventually a swab in the mouth ala: CSI put into a solution and spun down for a few seconds before application to a throwaway DNA chip pre-programmed with the most commonly used alleals will do the trick.

Yeah there are some problems with facial recognition software and hardware currently... its all about the kind of camera you use for image capture and your software alogrithms for processing the image. Unfortunately there are plenty of cheapie ones out there, and if the one the UK is using has a 10% failure rate then it means they're going cheap.
To do it right you need to use one of the solutions that corrects for ambient light and shadows and has a better processing algorithm.

What about contacts?

Actually, I relized that even if iris was used instead of retina, contacts wouldn't be a threat. They can't react to light in the same way as a true thing can...

If we supposedly "need" this, why not make every newborn be tattooed with a great big barcode from eyebrow to hairline?

The leniency accorded to criminals has caused us all to be treated like them.

[DukeP]

I think that theres a tendency to present crime way out of proportions.

Take the London Bombing. Its a very tragic event, and I feel for all the involved, which is more or less most of Britain.

But the number of people killed and injured number less than 1/1.000 of the number of people killed by cars in the same area. Every year.

We dont march for the abolation of cars. Instead we just calculate the risc of dying and weights it against the advantages given.

The same should be done with crime.
Take reasonable precautions and weight the burden of a heavier handed approach.

Is it really a good ideer to mark each living persons forehead with a tatoo? Or what about the far more efficient - mark each and every person with an implanted GPS broadcaster that logs your every move - hey - lets throw in a wireless voicerecorder on every person...

It would work.
But it is not (imho) a reasonable approach, weighted against the size of the problem of crime.

And so fort...

Feces, huh? Sucks if you swallowed too much dust - it's 99% dead skin cells, you know. Or heaven help you if you have a small child and kiss his boo-boo better. Someone else's DNA in your tummy!

[DukeP]

Nothing much of anything (except Corn - yuck) can pass the human digestive system - and especially not something as yummy as DNA - its candy for the engine.

The DNA in the feeces comes mainly from blood in the stoolen.

I have actually used that technic to do genetics on a population of foxes.
MUCH easier to go around and collect Fox Poo than to actually catch all the foxes in a forest and take a bloodsample.
