Stealing your own finger print

15 posts in this topic

I have just bought a new laptop, and it has one of does finger print thing.

The finger print thing works like this, instead of typing in a password every time you login to vista or any other login page, you can just scan your finger in the fingerprint thing that are on the laptop. Then the fingerprint will recognize that its you and log you in without using a password.

I think this is kind of good, because as we all know passwords can be hard to remember from time to time and just the convenience of just place your finger on the scanner makes it much more easier to log in to systems.

But this is why i haven't give this a try, i may be paranoid, but i know from a hacker point of view, you can never trust a system 100%.

The finger print thing has to be working like this, your finger print are linked up to this password, and this information are stored in your computer. But how are they stored? is it encrypted? and my biggest concern, my fingerprint... how is this stored??? I`m afraid that maybe its possible for someone to get my finger print this way. Brake in to my laptop from a network or just take it wile I'm at school and not paying attention...

Does any one want to go into this any deeper, any of you out there that have some thoughts about this. How is my finger print stored in the computer and can someone get to it ?

Have a good day to you all!

And remember, its never paranoia to ask questions :)

I can't offer any tips for that.. One thing that has me concerned with using finger prints is what happens if you cut your finger? Are you locked outside of your box until it heals? what if it doesn't heal fully? what then?

"your finger print are linked up to this password" in other words, you can just type in your password as you normaly would have done...

oh okay.. so you can type in your password , or use some hash the fingerprint reader generated to open the password file... Got ya.

Sounds like there might be something there to exploit...

It has been about 3 years since I had one. Mine was the USB type. I can't remeber the brand but it worked pretty nice. But you are right I took a gummy bear and put my finger print on it. Scanned the print and was in the computer. I hear that they are a lot more secure now and the one I had was a cheapy. I sold it a few months after I had it because it was not fun anymore. It is a little bit more security than just a password. You could put a really good pass phrase on the scan that would take a long time to crack.

Hahaha. I like that. Your laptop should have a fingerprint scanner, retinal scanner and voice authentication. But all that shit wouldn't matter if I have a copy of EnCase v.6. Muahahahhahaha

The official name I believe is "biometric scanners" and I have one on my laptop. Extremely handy because you can adapt the software so that it stores more than your log on password. You can use a different finger to sign in to your email, a thumb for binrev account etc.

In answer to Purple Jesus' question about cut fingers, the software ensures you have at least one finger scanned from each hand in case you lose a hand or something. Should you lose both, well then I think laptops are no longer for you!

As for someone stealing the print, seeing as not only stealing it but then reproducing it seem incredibley hard work, it's likely they'll get your laptop anyway if they're willing to go that far.

How can EnCase stand up to a Blowfish encrypted Stenographic file system?

:P

LOL, stego FS.

If major institutions trend toward biometrics, does anyone fear that "robbing" people of identifying body parts might become a financially viable crime for criminals to commit? Just something I've always thought about when it comes to things like fingerprint scanners...

These systems are kind of a joke, since they require a password in the first place, then give the user a choice of how to authenticate. It is just another single point of failure. They should require both fingerprint and a password.

About 4 years ago I had one, since im a sucker for gadgets. I did think it was neat to have different fingers open up different profiles. index = every day, thumb = girlfriend was near by, middle = porn, pinky = im having a party. Eventually I got paranoid, and stopped using it.

Biometric fingerprint readers are inherently flawed in that you leave your private key on just about everything you touch. Retinal scanners are more secure, but I've always shied away from anything that requires a body part i wouldn't want to lose just to gain convenient access.

Did you guys heard about that ideaPad? It uses facial recognition with its webcam. Pretty cool. But same thing with fingerprints, sometimes you can altar your face. I wonder if it does it on the contour of your face and things like that, and not how tan you are and what makeup you had on...

i use to work at a company called Identix(now its L1 identity solutions or something) but there device encrypted the finger print and passwords into a database hidden on the drive. it used AES256. as for other readers/software i can't say.
