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.

    The big thing about currency isn't the image so much as the ink and the feel of the cloth. That's not paper, it's linen, and you'd be hard-pressed to find a supply of convincing stock. The ink, while less of a factor, still contributes to the gestalt of cash - it affects the smell, and doesn't wash off when exposed to moisture.

  4. There are other issues by thinmac · · Score: 4, Insightful

    At least with U.S. currency, there are more issues than just he appearence of the bill. A big one, for example, is the material. If you printed out a set of nice new bills on standard copier paper, nobody would believe for a second that it was a real bill, low lights or no. There have been counterfiters who have bleached out low value bills, such as ones, and printed higher values onto them, like twenties, but I'm not sure how well your average inkjet printer would feed the cottony paper used for bills.

    I'm no currency expert, but I would imagine there are a lot of issues like this that aren't effected by the gross appearence of the bill for both U.S. and other bills.

  5. More positive idea by Bill+Lurker · · Score: 1, Insightful

    A more positive idea would be an electronic exchange/barter 'currency' widely used that would replace the centralized fiat paper money system we have now. This would have a lot of benefits, not the least of which would be to create more wealth for the common man and move power away from the centralized banking system.

    Not a lot of work seems to be being done on this,
    although it is clearly within reach now. You could even barter your open source programing skills to businesses who needed special features.

    I remember discussing this idea online on usenet 7-8 years ago, and having someone from the federal reserve saying it would never work, so the idea itself seems to have reached the ears of the banking system. Its a shame no one seems to be putting much work in it though. There were a lot of mastercard online debit and electronic cash systems going up before the dot.com bust, but none really set up with a barter system backing in mind.

    But the plastic money we have allows you to instantly see the difference between notes (Different colours and sizes), instantly tell that it's the real deal or a really expensive counterfeit (the clear plastic window), and it is just like having paper money in the way it handles, except that it's more durable (you can put it through the wash etc)

    The problem with US money (and I've lived there for a while), is that all the notes look about the same, all are the same colour, they wear out very quickly, and they're very easy to counterfeit. (At least to the point of using in everyday money transactions... how many checkout chicks carefully look over every note?)

  7. the penalties from counterfitting by luzrek · · Score: 4, Insightful
    I hate to say it, but only an idiot would counterfit any currency. Wired magazine had an article on this a couple of years ago. The pennalties for counterfitting in the USA is $250,000 AND 25 years in prision per offence. An offence is making, or trying to pass a counterfit note. It is also pretty easy to get caught, since most clerks have pens which can detect fake notes.

    As for the technical aspects. Take a look at the "big head" notes. Their is microprinting on the lower left side of the portrait. This microprinting is so fine, that light reflecting off of them scatters making it impossible to make a clear copy. In addition, there is multi-colored ink on one of the 5/10/20/50/100 numbers in the corners. And there is that pesky watermark. Oh, and ink from inkjets runs like there is no tommorow. A sweatty person couldn't pass those notes.

    All in all, the penalties for counterfitting and the risk of getting caught are too high.

  12. Currency Rarely Checked by suwain_2 · · Score: 4, Insightful

    I've recently started working in a restaurant, and as such handle a fair deal of cash. I have to say, I've never bothered to check currency to see if it's real. I know in some department stores it's required for the clerks to use a counterfeit-detecting pen on anything over $20, but this is certainly not the norm.

    The problem is that you can do a fairly lousy job, especially if you're giving me a wad of various bills to pay for your dinner. (ie, if you give me a bunch of $5's and $1's, I'd just throw them all in the register, most likely not even looking at them one-by-one.)

    Machines exist for 'counting' money (at extremely high rates) that automatically check various security features. Suppose cash registers started having an interface to this -- you'd stick the money in, and it would automatically undergo security checks.

    By the way, am I the only one who isn't too convinced that the new bill styles will be effective? The old ones will still be accepted, and if they're easier to forge, why wouldn't I just forge one of those? Frequently changing their design won't really counter counterfeiting (heh, no pun intended there).

    How so? The waitress comes by with a tray of drinks for a bunch of half-drunk guys sitting at a table in the dark, most of whom throw a bill or two at her and get on with their conversation. What is the waitress to do at that point? Pull her handy black light out and start scanning each bill? The guys at the next table are yelling for service, one of the guys at this table is trying to grab her skirt, and the bartender is loading another round of drinks on a tray for her to carry off.

    In real life, I run a movie theatre. When I'm selling tickets and it gets close to showtime, I have people walking in, literally throwing a wadded-up bill at me, and continuing right on into the theatre without ever stopping. And the next twenty or thirty or fifty guys behind them do exactly the same thing. Stop and check each bill for anything?? Heck, I'm lucky if I can just smooth them fast enough to get them into the drawer (and sometimes I can't; they end up in a little pile until things slow down a bit.) I don't think this is really unusual in many businesses. There simply isn't time or opportunity to do a thorough "investigation" when someone hands you money. All of the security features in the world are really of no value in these situations; that's just the way that it is.

    (We have no 1 dollar notes, we have $1 and $2 coins, much better to use).

    Don't get so smug. Considering the exchange rate for the AU$ and the US$, we in the U.S. have a coin roughly comparable to the AU$ coin, we just call it a half dollar (1 AUD = 0.658961 USD). I have a few in my pocket right now. We have no half dollar notes, so we're about the same there. We also have dollar coins, have for centuries, and although they are not as popular as paper currency, they are reasonably common. Again, have a few in my pocket and a bunch in my car. (And, of course, there are higher denomination coins that are still legal tender, but they are not in general circulation and not as commonly available unless you get them from a collector).

    The reason we still have paper $1 currency is that we have resisted people telling us that a heavy pocket full of coins is " much better to use " than paper money. The government has tried to tell us that, but we know they always lie, and experience with several dollar coins over recent years has born that out.

    The solution to that "problem" is simple, if you don't want the pennies just don't take them. Many places even have a small dish on the counter for just that reason, if you need a penny (to avoid getting 4 back) and you see one in the dish, just use it. And if you don't want a few pennies you get in change leave them in the dish for some other guy. Or just quit collecting them in your pocket, spend them on your next cash purchase that isn't an even multiple of 5 cents (that's what I do). Getting rid of them would just effectively raise prices on everything by several cents (by as much as 7 or 8 cents AU). We don't need that. If you're too lazy to get out a few cents when you have a pocket full of them and you make another purchase, you deserve to carry them around or leave them for someone who appreciates them.
