Counterfeiting With High Resolution Inkjets

Makarand writes "Thanks to the availability of low cost high quality inkjet printers, crooks are now able to produce currency indistinguishable from the real banknotes, at least under dim lighting conditions like that in a bar or a nightclub. The term "digifeiters" is being coined for counterfeiters that use cheap high-resolution printers to produce fake currency. Unlike costly color xerographic copiers that come inbuilt with features to detect security details on banknotes and stop currency copying, no cheap printers come with such feature. An anti-digifeiting system for cheaper printers may consist of printer driver software capable of recognizing data patterns indicating currencies of several countries." I wonder what GimpPrint would think of being forced to print or not print certain documents based on their contents.

    Other recent articles about counterfeiting have mentioned a proprietary chemical mixture that removes a vast majority of the ink from printed currency, yet leaves the security strip, watermark and colored fibres intact. Bills treated in this manner will fool those colored markers that most places uses for confirmation. You get a stack of $5s, 'bleach' them and reprint them as $10s and you've doubled your money, print them as $20s and you're up to 4x, print them as $100s and you're at 20x. If you take bills as part of your job, double check that the watermark image is the same as the face printed on the bill, and that the value in the security strip matches as well.

      Danville DQ Gag 'Talk Of Town'
      Restaurant, Residents React

      UPDATED: 6:42 p.m. EST January 30, 2001

      DANVILLE, Ky. -- It started out with a blizzard and now a Dairy Queen in Danville is getting an avalanche of attention.

      A woman who paid for her food with a fake $200 bill Sunday left with plenty of change. The bill had a picture of George W. Bush on the front and oil rigs on the back. "That's the talk of the town," Danville resident Joseph Bourne said. "It's got to be one of those dumb blonde stories."

      Added fellow resident Drew Hammond: "It's the kind of news I like to hear out of my own hometown. Usually things don't happen of great significance here. It gets a lot of attention."

      The 18-year-old employee has offered to refund the store. Her manager, Mike Tracy, tried to be supportive, and said that she probably was just too busy to notice the mistake.

      "We try to do things as quick as possible here," Tracy said.

      At least he's being a good sport about it. The restaurant is now distributing coupons on the backs of fake $200 bills.

      "We're going to play off this advertising a little bit and try to think of it as something positive," Tracy said.

      Local law enforcement said that the joke became a crime when the woman took off with all that change.

      "When the woman received the money and left with it, the joke ceased," Danville police officer Bob Williamson said.

      Still, because there's no such thing as a $200 bill, the woman, if caught, couldn't even face federal counterfeit charges. From here

    The process is called "leaching."

    The idea is to use a lower value note, say a one, then bleach the old ink off of it. Use your handy-dandy inkjet to print a twenty note on the paper that used to be a one. The one is well suited to false promotion because it doesn't have a florescent nylon strip that a bartender could positively verify the paper isn't a twenty.

    Since all US notes are the same size, feel the same, and mostly look the same it's easy to fake. I know the French franc, prior to the Euro, used different sized paper for different values.

    As a side note, if you've never seen the movie The Grifters there's a scene where John Cusack flashes a twenty at a bartender, asks for a beer, then pulls a slight-of-hand leaving a ten on the counter expecting the bartender to remember the twenty and give change as such.

    I know folks in the US complain about the Monopoly-esque look of other currency, but it's a hell-of-a-lot tougher to copy, easier for the blind to judge denomination from size, and easier for visitors to manager. Put a dime in front of a visitor and ask him the worth of it. He can't. Nowhere does it say "ten cents" or "10 cents." It just say "One Dime."

    A security thread is a thin thread or ribbon running through a bank note substrate. All 1990 series and later notes, except the $1, include this feature. The note's denomination is printed on the thread. In addition, the threads of the new $5, $10, $20 and $50 notes have graphics in addition to the printed denomination. The denomination number appears in the star field of the flag printed on the thread. The thread in the new notes glows when held under a long-wave ultraviolet light. In the new $5 it glows blue, in the new $10 it glows orange, in the new $20 note it glows green, in the new $50 note it glows yellow, and in the new $100 note it glows red. Since it is visible in transmitted light, but not in reflected light, the thread is difficult to copy with a color copier which uses reflected light to generate an image. Using a unique thread position for each denomination guards against certain counterfeit techniques, such as bleaching ink off a lower denomination and using the paper to "reprint" the bill as a higher value note.

    How does the plastic money handle?

    Pretty much like paper currency. A plastic note feels pretty much like a fresh paper note in terms of properties; a little stiff and textured, but still very pliable. By feel, they are obviously not paper, but they don't feel like you're playing with a cheap plastic wrapper either.

    The difference is that these properties don't really change as they get older. The notes get a few more creases in them, but they don't start to feel like tissuepaper like paper notes do.

    The creases are about the only problem; it can be a bit of a pain to flatten them out, but on the whole, I gotta say I prefer them.

    As a result, they last a lot longer in circulation - about 4 times longer. The down side is that they tend to tear catastophically; once a tear is started, it runs through the note fairly easily. However, it's very hard to start a tear in the first place (contrast with paper notes, which are easy to start a tear, but tend to tear slowly once started).

    What exactly is in that window - some sort of hologram or other image?

    Its a clear window, with an image in white ink in it. Each note has a different image. For example, the $10 note has a windmill. Its not a complex image - just a basic silhouette. There are some other security measures; microprinting, front/back alignment marks, that sort of thing. No RFID tags yet :-)

    I take it each denomination has its own color and size, but I think differing size would make it hard to carry around in your wallet.

    Each note is the same height, but each larger denomination is slightly (7mm, IIRC) longer. The longest note ($100) fits easily in an average wallet. A $10 note (all that I have with me at the moment) is about the same height, but about 20mm shorter than standard US currency. That would make a $100 about the same size as a US banknote. (I don't have one with me to compare)

    However, the real benefit is the colour. You look into a wallet stuffed with AUD bills, and you can tell if you have a little or a lot of money. See lots of pink, you've got lots of $5. See lots of green, you've got lots of $100. Single colour currency is one of the hardest thing I've had to get used to in the US.

The dollar is still has the largest foreign holdings, mostly thanks to oil trade being dollar denominated, asian currency holders, things like Euro-dollar accounts, and criminal activity (which still usually takes place in dollars. For a currency to be weakening it should depreciate against all three, however, most of the smaller currencies are directly or inderectly linked to one of those three currencies (mostly the Dollar or Euro).

Following the removal of the gold standard worldwide, most currencies trade on a floating market, meaing that unless the government takes careful action to prevent swings in the currency, its value is determined by market transations. While it used to be that speculators drove trading (George Soros made his early billions by breaking the London central bank) today the vast majority of transactions is related to either foreign investment or imports and exports. Complete speculation: The increase of the Euro is likely the result of large foreign investment portfolios moving into Europe and out of the US. Some of this is Saudi Arabian, and driven partly by politics, and some of the trading is driven by Eropeans who are chasing yields. Our large trade deficits are typically made up with foreign investments in the US, which was one of the main reasons the dollar remained so strong throughout the 1990s while trade deficits remained at very hight levels. Now that foreign investors are realizing that they might not get outsised returns from their US investments, they are beginning to look for investments in other regions. Economics is pretty self regulating, the weaker dollar will make imports more expensive, and exports cheaper which should reduce the trade deficit, assuming the investment change is not temporary.
    4. A falling currency benefits people who borrow from foreigners (if the fall is unexpected) and exporters. A rising currency benefits those who loan to foreigners (if the rise is unexpected) and importers or tourists, who travel to the foreign country, but are effectivly importers. Exporters benefit from falling currency in the following way: Lets use Ford and Nissan as the example companies, when the dollar falls relative to the yen, Ford, who still pays most of its employees in dollars, can now sell a car in Japan for the same Yen price and reap more dollars after the currency transactions. However, when the dollar is rising, Ford's dollar value of a Japanese sale, is lower and they still have to pay their employees in dollars.

    My first real job in 95 was at a Kwik Kopy. From about 6 months after I started, we (well, a couple of us) were aware that the color copier tagged it's serial number on every copy it made.

    When I first discovered it I was working with the head typesetter. We couldn't figure out what this strange very light interference pattern on every printout from the color copier (which had it's own RIP) was. It was the same regardless of whether we were printing or copying, and regardless of the content, and it was an identical pattern on every sheet. That particular copier (as far as we could tell) didn't have any moving parts that synced with the page ends well enough for it to be a physical problem. And if we put the machine into black and white mode it went away.

    It took several weeks of me badgering the service guy, and 3 service calls for 'Image Quality', before he finally admitted what it was.

    We weren't really surprised, the copier had other more noticeable anti-counterfitting measures as well. While we never had a problems with copying, occasionally if you printed a file from the network with a complex enough swirled pattern on it (which one of our typesetters was unfortunately fond of), any green on the page would get shifted towards blue. We solved the problem by firing the typesetter. (For unrelated reasons, of course.)

    The smaller black and white self-serve copiers also apparently had currency detectors (of an informational, not active type), which we found out about when one of the machines had a service call for a broken belt and the tech qustioned us because he said the currency detection register had been set. Since none of us had seen anybody trying to copy money, and it was a black and white machine, he said it was likely a mistake and he didn't even have to report it, but asked us to keep an eye out.
