Biometric Payment Arrives in a Store Near You

"A chain of Florida convenience stores has begun accepting fingerprints as payment, using a biometric system called Pay By Touch. The company is a Bay-area startup backed by $130 million in VC cash and the acquisition of BioPay, a Virginia-based biometrics firm that's already done $7 billion in European transactions. From the article: 'The company is a bit puzzled by customer privacy fears. After all, they say, how can using a unique fingerprint for identification be riskier to theft than a plastic card, key chain token, or account number? ...The fingerprint image recorded is not the same as those collected by the federal government or law enforcement.'"

      I could probably travel the world on a single package of gummy bears and a set of prints lifted from the sides of soda cans, tossed in the trash outside the convenience store.

      Just remember though, outlaw gummy bears, and only outlaws will have gummy bears.

      Another issue is that your fingerprint must be stored somewhere else in a database. This leaves room for an attacker to use a digital copy of your fingerprint for other transactions.

      Somebody please correct me if I am wrong, but this is nowhere as safe as a private/public key. If the external party saved your public key, there is no worry. However, your fingerprint does not have two version, one being public, and one being private for signing. On the bright side, they can combine a pin number with the fingerprint, but the stores I have visited (Farm Fresh) do not require a PIN. Only a fingerprint.

    Didn't Slashdot run a story a while back about a supermarket fingerprint pay
    system that was tried a year or so ago? It could be faked out REALLY easily
    using a Gummibear.

    I can't find the slashdot story - but check this out for example:

    Does this new gizmo do something magical to avoid this rather easy attack?

    Just google gummibear and fingerprint and you'll find a gazillion How To
    articles.

    If the biometrics guys are 'a bit puzzled by customer privacy fears" then
    they are horribly ill-informed!

    I can avoid leaving my credit card lying around for someone to steal - but
    it's very hard indeed to avoid leaving my fingerprints in all sorts of
    public places. If I could find out how to defeat their scanner so easily
    with about 10 seconds of Googling - you can be very sure that the bad guys
    will be lining up.

      Touching a "gummy bear" in a way in which it wasn't intended is just plain wrong. Gummy bears are meant to be eaten not fondled.

      Also, do you know how old that gummy bear is? You might be touching an under-aged gummy bear.

      Superglue, cameras, blank circuit boards, and etchant are required to make the mold. All crap I have had laying around my house for the past 20 years. And gelatin is require to make the fingerprints. That's in my pantry, and not so old. The last two ingredients are knowledge (see the link) and the lack of ethics that keep normal people from committing crimes (in sadly short supply.)

      "Gummibear fingerprints" are not certainly not FUD (although they're not made from real gummibears.) They're a real attack that's easy to make, and fun to eat!

      The reasons they'd work so well for fraud are numerous. First, while it's pretty easy to keep track of your fingers, it's virtually impossible to "guard" your fingerprints. You leave them everywhere -- your phone, doorknobs, keyboards, dishes, plastic bags, everywhere. It just takes a little bit of "Hardy Boys Detective Handbook" work to photograph them. Making a circuit board from a photograph is something I did a lot in 7th grade, but nowdays digital cameras and laser printers are more common than photographic enlargers. And even I can mix up gelatin without burning down the kitchen.

      The neat thing is that gelatin itself is the ideal material for forging fingerprints. It is simply animal protein (it's pretty much ground up cow hooves and collagen, if you want the real details.) It's biotic matter, so it has roughly the same electrical capacitive properties as human skin. It's thin and transparent, so a "pulse detector" that senses the infrared pulses given off by circulating blood can see right through it. And if you wet it, it's kind of sticky and can easily be applied to the fingertips before heading to the cash register. Once applied, they're virtually impossible to see. Gelatin is almost indistinguishable in every way from human skin.

      Everything that a fingerprint scanner can be built to look for (at a cheap enough price to sell to grocery stores) is right there on your fingertip. Even if the alarm bells sounded and the guards came running, you'd still have time to pop your finger into your mouth and eat the evidence.

    From TFA: The company pledges not to sell or rent personal information, or access to it.

    I read this line too and it made me want to scream. "Company pledges" are worth exactly shit these days. "We pledge to protect your privacy and retain the right to alter this pledge at any time." "We pledge to never sell or distribute all of this personal information that we insist on gathering, really, unless we're bought out by another company that doesn't pledge this."

    I don't want pledges. I don't want them to have this info, period. I don't want to receive marketing from them any more than I want it from third parties.

    Now, if there was accountability behind these pledges, such as "We are bonded for a $10,000 per customer coverage to never leak any customer information" or "Under penalties of perjury with a minimum of five years prison time to be served by each member of the entire Board of Directors, we pledge to never sell or otherwise distribute any personal information collected by us. Furthermore, under threat of the same penalites we pledge to use this information only for verification of your account, and never for marketing purposes of any sort."

    Those are some pledges that I'd be slightly more inclined to believe.

    Some people's fingerprints can't be scanned by these machines... Last year I went to Florida and they have fingerprint machines at all the big theme parts and at the airport. None of these machines could pick up my prints... And every second time I used them I got rejected ... So this flawless technology is anything but... I do nothing special with my hands, so it must be one of those "from birth" things... But if you're unlucky like I am then don't expect to be paying with your fingers any time soon. I am not looking forward to going back though American customs as I know the fingerprint machine will reject my prints and I'll get sent home or something crazy.

    The 7 digit number is probably there to conform to the normal standard of requiring two pieces of ID for confirmation of who you are. The 7 digit number is one, and your fingerprint is the other. This not only confirms your identity but also confirms that their records are accurate with respect to any identification that you have previously provided them with. If something doesn't match up with their records, they can ask you for details and confirm your identity another way before processing your payment.

    It is important to know that these sensors are not optical in any way. They are using sensors similar to those from Authentec which use an RF scan to penetrate the first layer of skin. This eliminates problems with "too wet" and "too dry" fingers and also prevents spoofing by just about everything except cutting the finger off.

    There are some systems that can be fooled much easier, but they are not being used by PayByTouch. Nor is anyone serious about using a fingerprint scanner anymore.

    Microsoft sells an optically-based fingerprint scanner that can be fooled by latex molds, gummi bears and lots of other stuff.
