      That should require the same amount of difficulty as getting a credit card in somebody else's name. So, in that sense (setting up the account), this fingerprint system has no advantage or disadantage over a credit/debit card.

      However, it has a huge advantage in accuracy of authenticating the owner of the account. I will submit that it is far more difficult to forge a fingerprint than it is to forge a signature (usually the only authentication system used to validate a credit card purchase).

      Fraud is a considerable thing to deal with for a bank - many times the person who was defrauded demands not to pay and the bank does as their customers want. Getting your ATM card stolen by someone you know can cost you a lot of money - sometimes up to ten times more than you lost if you try to push on with the investigation. A bank isn't the police, and the police can do little in these situations even when there IS a picture. In the end more is lost that what was stolen in the first place.

      Fingerprint technology could bring those fees down, but we will need to see it work.

      Part of the problem with current credit cards, and with this system as well is, as the parent said, the 18 year-old clerks. I'm speaking from experience, as a 17 year-old clerk at a clothing store that does lots of sales with credit cards. I realize that credit fraud occurs commonly, yet I don't do anything about it. I rarely check signatures and only ask for photo id if the CC says to. There's no reason for me to do otherwise. No penalities from the cards are directly passed on to the cashiers. If some accountability was placed on me, like a 50 dollar fine for each stolen CC I allowed to be used you can bet I would be checking alot more signatures.
      Another part of the problem is lack of consumer awareness. You would be amazed at the number of people that don't even bother to sign the back of their cards. We're supposed to ask for id in that case, but when you've got a line of 15 customers, waiting for someone to dig their license out isn't the greatest idea.
      To solve the problem, I think credit cards should come with a mandatory PIN number, one which isn't stored on the card (so theives can't crack the card). In addition, some responsibility is due for the cashiers. If my cash drawer is 5 dollars under (or over) what it should be, I get written up. Why not do this for cards not used by their owners?

  8. Trusting your biometrics to anyone ? by Oestergaard · · Score: 5, Insightful

    It's beyond me how anyone would trust their biometrics to random companies (or other entities). Hell, I wouldn't trust the government with mine (they can take prints from my dead cold hands).

    The problem is, that they are not just creating a "hash" from your prints - they need to store the exact print in order for the recognition to work. This means, any script kiddie lucky enough to get into their database, will have the prints.

    The next logical step is, to hook this system up to the feds and interpol (post sept-11 this is not fiction!)

    The real problem will be, that people trust technology blindly. When I "check out" of the store, putting my thumb on the reader, and the alarm bells sound (and the big "armed and dangerous, shoot on sight" sign starts flashing), guards, police, whatever, will trust the damn machine.

    Now if one could trust that the responsible parties would (and could) ensure "absolute security" around their biometrics systems, there really wouldn't be that much of a problem. But believing that IT departments in regular companies (or even government agencies) who all live with finite budgets will ensure that their back-end systems are un-crackable is naiive.

    I'm sorry to debunk you Ms. Angela of LANL, but your statement is nonsense.

    I design software for biometric systems and although I don't know where they are installed at, the US Gov. is our largest client. *NO* current systems verify a third dimensional component. The neural network that IDs the print is fed many parameters. Amongst them is color (as you stated), thumbprint temperature,ambient and outdoor temperature (because the human extremity body-temperature is so dependent upon the environment), plus many more features from the actual 2-Dimensional image. There is no 3-D component.

    You might argue that the angling of the scanning lasers adds a third dimensional component (a shadow) to the 2D image, but this is still something that could be duplicated given an image.

    A very basic components analysis of the Neural Network will show that the thumb temperature is an ineffective means of classifieing the print, yet where I work, marketing insists that we continue to use this. That is why we have tried to increase the temperature importance by also including ambient temperatures, but mostly, the temperature is useless as a classification feature.

    As far as taping a photocopy of somebody's fingerprint to the scanner this won;t work. Our scanners are color images, and the light from the photocopier has to come in at the same angle as the lasers. Using a pane of glass, a red light angled in the right direction, and a camera, we have been able to create photos that pass for fingerprints ~97% of the time. The percentage would be slightly increased if you kept the image in your pocket (body-heat) until placing it on the thumbprint scanner. This number approaches the number of false-negatives that you get with any thumbscanner.

    Using biometric information creates a *real* problem for identity theft. Bruce Schneier points this out in his second book. If the advanced criminals can't reproduce your thumbprint, then they might as well intercept your biometric going from the scanner to the computer and reproduce that on all subsequent machines.

    This is something that I will definitely opt out of in the future. Using a pseudo-random key generator on a cel-phone and having it transmit the key would be more accurate than a biometric.
