Fingerprint scanner

[Nikita]

I think this is pretty cool. It could potentally eliminate fake or copied prints. Not practical for your laptop but for physically access a built in podium with one of these puppies would be pretty sweet. Also that would be pretty bad ass for that underwater evil lair we all have laying around.

Water Proof fingerprint scanner.

Re: Fingerprint scanner

Shows that readers are getting sensitive enough to read the actual rigdges rather than sweat built on them. Makes lifting prints around the office for later hijinks a little harder, but not impossible.

In severe service areas I can see having the unit sealed being more an advantage than any 'waterproofness' is

"Put your PC next to the swimming pool, dip this fingerprint scanner in the water, and whilst you're scuba-diving in that 1.3m deep swimming pool of yours, just swipe your finger on the sensor and there you go, you're into Windows!"
Yeah, I always do that. Put your expensive 2500$ laptop right next to your swimming pool (the device isn't wireless yet) and jump into the water... Genious. I like the idea of "getting into windows." The fact that it is *sweatproof* is one of the biggest features, I think. I want one of those built into my mouse!

@Renderman
Have you ever lifted such a print in real-life? That would be ... wow ... I would feel excited if I ever was to do that. That's what turned me into the hacking world. It's simply exciting. (And it feels good like **** when what you've been programming on for weeks finally gets to work!)

I've been able to fool old POS scanners, have;nt tried anything <5 years old. Got some ideas though and friends with gear...

OK, so am I bringing the fingerprint kit again? It seemed to earned me an extra TSA search last year. I think it was the autopsy spoon that really confused them.

As far as reading the ridges, I doubt that the waterproofing will eliminate fake or copied prints. Of course, if you really want to bypass it, you just take the fingers, like those thieves did to that poor SOB in Malaysia

Are you sure it was just the spoon and not the rest of the items combined with the autopsy spoon? After all why would one want to travel with dual-use magnetic powder, a feather duster and such? Unless of course.....

I should, like the past few years, have a pack of lighting-lifters with me if anyone wants to use a few for any weird projects or whatnot.

I worked at a place where not only were we able to successfully bypass the print scanners leading into the datacentre with silly putty, but it actually had a better read rate than a live print.

Biometrics are OK as a secondary authentication factor, but using them as the primary is just irresponsible given their current state of maturity. Of course, there are more accurate systems out there, but they aren't always practical to use across a broad range of situations.

The autopsy spoon was for a demo. The feather duster was for the "of course..."

Modeling clay (for a mold), and silicon caulk can produce a model which is damned near indistinguishable from a live human finger.

The technology decends from AFIS systems used to take "ten-prints" or "arrest card" prints. The algorithms are designed to make a match/no-match decision, but are not designed to make a "match-but-fake" decision.

Re: Fingerprint scanner

I more or less meant lifting the print from the scanner itself if the scanner always has running water going across it. Which is why I felt this was super cool, not as somethng that can read prints with sweat beads and yadda yadda. The fact that it will read it while water is constantly running. Which i would think can help reduce the possiblity of lifting prints from it, and using some cheaper techniques, like those seen in movies to apply a copy/ lifted print to the scanner. Especially perhaps if there was a solution in the liquid meant to remove oil build ups and yadda yadda (And the note about the pool and laptop or whatever in the article, I think that was sarcasm)

I have a USB finger print scanner a vendor sent me. I'll be glad to bring it to DC and give it to you if you want.

I think lifting a print from the actual scanner would be my last choice. A little constructive social engineering could give you a print you could just take with you and reproduce at your leisure.

One other thing we learned while messing around with Silly Putty that I neglected to mention earlier: it's not as easy to get a readable print from the scanner itself as people may think. Yes, it's definitely doable, but the number of variables and practicalities involved make it a less desirable approach to take in a lot of cases. Typically the main problems involved the cleanliness of the scanner affecting the resolution of the print, damage to the print sustained in transferrence, and the need to still create a three-dimensional representation of it.
