      Technically these two sentences are in opposition to each other. The vast majority of credit card fraud is online fraud, not in store fraud (which is dropping and continues to drop.) The reason those two places, in addition to many other places (Chipotle is one that comes to mind) are not checking the signature strip is because the in store credit card fraud is too unusual to care about it. That also answers the question why photographs on credit cards are not being persued--it simply isn't econommically viable/justifiable.

      The gummy fingerprints defeated all the live finger detection systems handily.

      The gummy mold is just an ordinary photo-etched copper-plated printed circuit board. (I made lots of them when I was a kid from stuff I bought at Radio Shack.) Take a photo of a fingerprint. Make a full size transparency of it. Expose the photosensitive circuit board using the transparency as a mask. Etch the circuit board. Pour ordinary hot liquid gelatin over the board in an even (3 mm or so) layer (the original paper gave a recipe, but you should be able to use any old recipe for "Knox Blox". It's just ordinary gelatin mixed with boiling water.) Harden it in the refrigerator. When it's time to use it, simply cover the tip of your own finger with the sheet of gelatin.

      It passes live tests easily. The thin layer of gelatin is almost invisible. It's transparent, so your own skin shows through. It's conductive: it has a moisture content similar to your own body. And it's warm: your body heats up 3mm of gelatin quite rapidly.

      And once you pass through the scanner, you just lick your fingertip and the evidence is gone.

      Extensive testing of this was performed against eleven different fingerprint scanners earlier this year. EVERY TESTED SCANNER ACCEPTED THE GUMMY FINGERS, including those advertising "live and well detection", with acceptance rates varying between 65% - 100%. John Young's website has a copy of the paper here.

      I am not familiar with Kroger's system, but from the article it looks like they designed it correctly.

      Fingerprint scanners are lousy at identifying you from a large database of scans, too many false positives (hash collisions). What fingerprint scanners are good for are _confirming_ that the scan is you. My guess from the article would be Kroger's is using the scans like a pin code, the user presents their club card and the scanner is just used as a quick verification that the customer at the checkout is the person who signed up for the card (and linked it to some payment system).

      Privacy concerns are pretty minor (assuming you already agreed to let them track your every purchase by getting the club card) Most of these scanners use a system that hashes key features of the fingerprint, it isn't possible to recreate the actual fingerprint from the scan (it is possible to copy the hash, just like a pin, making it usless in an untrusted env). So the police will not have much use for this db.

      Its sound like a good idea, much better than a credit card, which relies on a bored checkout clerk verifying a signature.

      And thousands of times better than Speedpass, which AFAIK sends a unique id number (the secret, essentially) in cleartext over a radio link!.

    Such a system relies on two major assumptions:

    • Your finger is unique and physically secure (hopefully true)
    • There's no "your finger" equivalent that someone could use (patently false and hopelessly naive)

    The problems with such a system:

    1. It's easy to falsify. It's actually almost trivially easy to fool a fingerprint reader and fake someone else's fingerprint. (note that the type of gelatin Matsumoto used is seaweed based -- a little stiffer and a bit different than what we use in the states, but I'm sure you can find it here in an asian grocery store or similar)
    2. It's not verifiable. There is no challenge-response method possible with your finger to verify that it's even your finger, unless you want to add an embedded subcutaneous microchip, as in a smart card (but then why a fingerprint at all?). Worse, no such system actually checks your fingerprint; it computes a numeric hash of some sort from key features. Any hackery that can get you into the system behind the fingerprint reader means you just use the numeric hash (VERY easy to copy!) instead of a fingerprint. Consequently, it's no more secure than a credit card number in this respect.
    3. It's not unique. Two words: hash collisions. Not such a big deal for authentication, but a real problem for identification.
    4. It's not revokable. Given the above, if someone steals either your fingerprint or its hash, it's not like you can just get a new one, like you can a credit card number. You'd better hope the system at least allows you to switch to a new finger (and hope you don't run out of fingers). In the worst case, then, it's actually LESS secure than a credit card.
