U.S. Offers $50 Download

chill writes "CNN is reporting that the U.S. Government is offering low-quality images of its new $50 bill for artists, students and others who discover that their computers, scanners or printers won't allow them to view or copy pictures of the new currency, due to mostly-secret anti-counterfeiting measures built-in. This anti-copying technology has been discussed on Slashdot before. Now to go and test my new Epson scanner and printer to see if they're affected!"

    Uhhh....those little yellow 20s are a major part of the digial anti-counterfeiting measures!

    The pattern of the "0"s is something you'll see on Euros, Pounds and many other currencies. This allows software to easily recognize one pattern, at almost any angle, and not have to have separate code for each country's currency.

    "It's simpler than you might think. All compliant notes bear a pattern of five tiny circles. On the Euro, the circles appear in a constellation of stars; on the British £20 note, they're disguised as musical notation. On the new $US20 note, the pattern is hidden in the zeros of a repeated background pattern of the number 20. Imaging software or devices detect the pattern and won't play ball."

    Couterfiting occurs because people are careless, yes the technology helps prevent it somewhat, but after working as a cashier in my midteens I was amased to how my fellow coworks would get fake bills and accept it... some of them looked so fake it was unbelivable.... also when i worked as a cahsier i noticed that these pens ( our only tool we where told to use to prevent counterfits) could easily able to give the wrong results on conterfits by just simply coating the paper with a fake plastic not enough to really feel it because of this it never alowed the ink to change color idefenying counterfit...

    There are a series of 5 circles in a specific pattern... in the case of the new $50 it's the zeros in all the little "50"'s on the back.

  8. "SPECIMEN" text can easily be removed by Jagasian · · Score: 4, Informative

    Opening up the PDF in xpdf for Linux causes the bill to be rendered and a few seconds later, the red colored "SPECIMEN" text is written ontop of the bill. It should be hard to remove this top layer, resulting in a government provided digital copy of a $50 bill. Lovely.

    Didn't the government acidentally make this mistake with CIA documents that had people's names blacked out with a separate top layer, that was easily removed?

      Did it in windows in 5 seconds with Adobe AB Standard V6.
      Click on the menu item "Advanced" -> "Export All Images..." -> save in some location.

      Done sans the red 'Specimen' text.
