Biometric Payment Arrives in a Store Near You 206

"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.'"

        It does not matter. A person's fingerprint is not a secret. You leave them everywhere. (Unless you wear gloves all the time.) I assume the cashier watches the customer scan their fingerprint, so they know the fingerprint belongs to the customer. If someone comes in and tries to scan a finger not connected to anything, the cashier will probably suspect something.

      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.

    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 that's tapped into a computer or spoken over the phone?

    WTF? How can they say that? Don't they know how many times each day people lose their fingers? Not to mention the countless times people give each other the finger! (Done so a few times myself.)

    Also:

    It's similar to the finger-scan technology used at theme park gates. Those systems take measurements of patrons' hands and fingers and link them to a multi-day pass to prevent several people from using one person's pass.

    I experienced this at Epcot... in Orlando. I don't know if it was in its experimental phase, but it introduced lots of confusion as people entered the park. And, it was not clear how or where it was used the rest of the time we were in the park -- if it was exclusively to prevent abuse, so be it, but it was an eerie experience at the gates.

    I do wonder about the statement: (FTA)

    The company pledges not to sell or rent personal information, or access to it. The fingerprint image recorded is not the same as those collected by the federal government or law enforcement.
    How can that be? I know my prints are on file (Top Secret clearance, cool!), but I wonder how these prints would differ. Are they storing some kind of hash with no backup of the original scan or image? Weird, but doubtful.

    I think this is great technology as people get more comfortable with it. I would (and do) worry about how soon people get good at counterfeiting fingerprints. Thought I'd read a couple of articles on that very hack and that hacking fingerprints turned out not to be too very hard. Any resources on that?

    Regardless, great point about it not being that much different (and quite a bit less likely to wander off) from keychain fobs, credit cards, etc.

        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.

      Perhaps because most people are more comfortable with having a finger chopped off than having an eye (or both) ripped out of their head?

      On a smaller scale, they're probably also more comfortable with laying a finger on a pad than putting their eye up to an eyecup or having a "guaranteed safe" laser probe them in the eye.

    Cub Foods also uses it. You need to enter a 7 digit number along with your finger print. It really didn't seem easier than swiping a card and entering a four digit number, so I didn't go with it. They suggest using your phone number for the seven digit number. I imagine the number is needed to make the database lookup practical. I wonder what would happen if LOTS of people started using the same seven digit number "1234567"...

      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.
    • I'd bet there are many duplicate fingerprints as far as their scanners are concerned if they need you to use such a long pin. The system probably functions primarily on your pin, using a relatively low quality fingerprint scan for verification or duplicate resolution in case two people have the same pin.

    • *most fingerprint systems don't store the actual fingerprint*.

      The easiest, most computationally inexpensive way to check fingerprints against a database is to hash the print that you found at the crime scene--or the point of sale--and compare it to a database of hashes stored in the same way.

      If you have the hash database, you have the fingerprint. Just because it's not the *same* hash as what law enforcement uses doesn't stop the NSA from using it against you. If you had more than one hash database, you m

    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.

This way, if your fingerprints get compromised, your PIN is still unique and you can change it whenever you want.

    We use finger print readers where I work. This, of course, only applies to the system I'm familiar with, but I doubt the store one is that divergent. They don't store anything resembling an image, but rather a numerical encoding of a given number of key points. I get the impression the actual process involves some kind of hash number validation.

    The reason that "the fingerprint image recorded is not the same as those collected by the federal government or law enforcement" may be chillingly pragmatic. We were told when implementing our system that if we stored fingerprint data up to government specs we would be required to provide that information to the government. As a result our company, and most others, store data below the threshold that will get them noticed by the feds.

    The fingerprint validation itself is somewhat fluid. Most people don't press the reader the exact same way twice in a row, the finger distorts under different levels of pressure, reacts to environmental changes, and even the current health of the individual. This kind validation requires a level tolerance to be set.

    Some individuals never seem to get a good read, the tolerance for such people needs to be loosened to get any kind of positive feedback. As a result, some of our employees could hoist a big toe on the reader and probably get a pass. I simply wouldn't trust these things not to mistake me for the granny with the bad fingerprints.
