Xerox Exploits Printer Flaws To Make Pseudo-Holograms

Red Wolf writes "A chance discovery by Xerox lets printers superimpose glossy images on regular printouts, creating the possibility for document authentication along the lines of holograms on credit cards. The new technology, called Glossmark, can use ordinary office printers to superimpose a glossy image on an ordinary printed document in a way that can't be photocopied or otherwise easily reproduced."

    Can be produced by existing Xerox printing solutions.

    I don't really see how this works. If there's a document I want to fake I just whip out Quark and reproduce the Glossmark on my Xerox printer. Wha?


    "Can be produced" isn't the same as "can be reproduced." Sure, I guess you could print out your own copies -- if you had access to the original images. If I understand correctly, most of the point is that you can't just scan the image and retain the glossmark effect.
  9. Color laserjets? by groove10 · · Score: 5, Informative

    From reading the article (yes I read actually read it), it would seem that only the "wax" type color laserjet printers have this ability. There was a Slashdot article a while back that dealt with color laser printers and alternatives to inkjets. The news.com.com article does specify the models or type of printers where this was discovered. Any other info on this?

    I'm sure some hackers will try to do some mods on their printers to control this as well. {cough}fake holograms{/cough}

      From the books I've read about Xerox, it sounds more frustrating than cool to work in their R&D. You invent all this neat shit, and the copierheads at Xerox dont "get" it, so Xerox doesn't market it.

      Your only hope is to go to work for the other company that will eventually pick up the technology and make a mint with it, or to leave and found your own company to make what you invented.

      And with all the "intellectual property" crap being thrown into employment contracts these days, the latter of those two options is probably right out the door. If Bob Metcalfe was working at Xerox these days, he damn sure wouldn't be allowed to leave and start 3Com to sell ethernet hardware that he whipped up on Xerox's dime.

  11. So let me get this straight... by i8a4re · · Score: 5, Interesting

    Companies are going to adopt this technology because they can create an "uncopyable" product (probably tickets, coupons, and other vouchers), and they already have the technology in their office.

    In the mean time, some counterfeiter who has the same technology in their office or home will simply copy the main image and recreate the superimposed image in a graphics program. Then he will be able to print "authentic" tickets or whatever whenever he wants.

    The number one blockade in stopping conterfeiters is the machine that produces the items they want to counterfeit, not the complexity of the artwork or image. Sure, the complex image and holograph help, but that is mainly because consumer level and most business level products can't produce images that complex. Give me a few months and I could make a damn good couterfeit $20 bill if I only had the paper and the press that makes them. It wouldn't be perfect, but the average cashier wouldn't notice.

      And your aunt could be your uncle, if she only had balls and a dick.

      You might get the paper by bleaching one-dollar bills, but you damn sure ain't getting the press. The Intaglio process used on U.S. currency applies the ink to the paper at great pressure, and in sufficient quantity to achieve an embossed effect. U.S. currency has a distinctive feel because of this, and were you to slip an inkjet or color laser-printed bleached-single $20 bill into a stack of $20s you used to pay for something, the cashier would notice it didn't feel right before he/she noticed it didn't look right.

      Intaglio presses are huge, somewhat rare, and cost in the millions of dollars, so you ain't gonna but putting one in your basement anytime soon. If you had the financial capability to do so, you wouldn't need to counterfeit money.

      Having said that, the Secret Service does have counterfeit bills produced by Intaglio presses, and believe that they are being produced by the government of some country hostile to the U.S.-- because that's the kind of moxie it takes to get your hands on an Intaglio press.

    I've noticed it too on photo paper. The way inkjets [i think that's what they're using] layer the ink can create a raised effect on certian printers ...though I mostly use HPs. The idea would be that someone couldn't just grab a document out of a file folder on your desk and color copy it--there's no change to the color..it's not really reproducable..it's too subtle. Heck, you could even put a serial number in a black box and number every copy you print! Then even with access to the hardware you couldn't just reprint something.

    It doesn't look really useful for preventing professional counterfieting, but for "casual" things [retail reciepts, HR files, inter-company corrospandance, etc.] It could come in handy for quick verification.
