How To Fool a Fingerprint Security System As Easy As ABC

just dont use superglue to get a print of your iris. :)

"Ouch my finger is stuck to my eyeball!"

LOL. OP, yes and no. Iris scanning, which takes a look at the outside of your eye and compares it with the database, has been blown right out the water. A high-res photo, an inkjet printer and a few seconds work lets you beat them, even the ones that look for a pulse. Retina scanning, which shines a light into your eye and compares what it sees with the database, is till secure, mostly because the scanners are so invasive that you'll never get a retina scan without the person working it out, unless you pretend to be their optician! Of course, you could set up a fake eyeball somehow, but it's a lot harder, plus there tends to be a guard monitoring the scanner. As ever, as with all biometrics, positive auth is all well and good, but the lack of repudiation ruins it. Someone steals your iris print and abuses it - how do you stop it? You can't just reset the password - you only have two eyes. Or only one eye. Or, indeed, what do you do for the blind born without eyes? UK law to prevent discrimination means you'll need another system.

actualy, you wouldnt cut the finger off, the laptop or computer actualy looks at electro magnet pulses in the finger to see if its alive ;) or whatever its called

electro magnet pulses, eh? Not sure... I've not got a robot finger scanner, mine only work on humans. There are a few high-end scanners that check for a pulse. (That's a regular pulse from the beating of the heart, nothing fancy like you've got, Mr. Robotnic) Few and far between. There are two main current technologies, one uses a solid state heat sensor that is so sensitive it can pick up the heat differences between the ridges of the fingerprint and the troughs, and there are capacitive types that are tiny multi-point touch sensors. The oldest ones use a CMOS camera or the like and do an optical comparison, but they are terrible at matching a print as any dirt, ink or dust means it fails. IMO there are no fingerprint scanners ready for prime-time without specialist training and support. Even the multi-million pound IRIS (eyeball) scanners at UK airports are off-line now due to not working. Biometrics isn't dead, but it is a very limited use technology.

so if they take an amputated finger and put it there it will say that it is dead?

what is this Al Queda? dude why are u talkin about cut fingers???lol

AL Queda? It sounds like a taco.

thats how they reel u in

?

duz sound quite tasty

Yeah

oh yeah... Il just turn it intoa removed by community request

hahahahah

ERROR - That is not a live finger,take it back to the hospital and return it to its respective owner,NOW!

what?

nevermind

whut?

mna wyh bda selping? there is a spell checker Built into Firefox you know

ok but its faster when its misspelled

It won't Hurt to spend a few seconds right clicking on red underlined text

um... wut kind of laptop do you have?

wait, then wouldnt it be able to tell that the wood glue isnt a living finger?

Uhh... No because your finger is on top of the dummy fingerprint with is so tediously thin the electromagnetic pulses penetrate right through it.

somehow I think they would know if you where using their computer after that.

you cant use electro magnetic pulses to check if somethings alive. i cant think of any way except heat, and your body heat would conduct through the copy, wouldn't it?

But then you can always use a lighter set at a distance...

i don't think it will recognize 700+ degrees as alive

Or you could trick them into placing it in the convenient hole for 3 hours while making a mold then using ballistics gel to make a portable finger. They wouldn't be suspicious. Why would you think that :\

Were do you get that?
