EURion constellation A number of new designs of banknotes contain a pattern known as the EURion constellation which can be used to detect their identity as banknotes to prevent counterfeiting using modern inexpensive digital scanners, colour printers, and image processing software. The EURion constellation consists of a pattern of five small circles, which is repeated across areas of the banknote at different orientations. The EURion constellation was first detected on the new Euro banknotes. www.wapipedia.com /wikipedia/mobiletopic.aspx?cur_title=EURion_constellation   (177 words)

EURion constellation Information The small circles of the EURion constellation are clearly visible on the centre-left of 10 euro banknotes. The name "EURion constellation" was coined by Markus Kuhn, who discovered the pattern in early 2002 while experimenting with a Xerox colour photocopier that refuses to reproduce banknotes. The EURion constellation first described by Kuhn consists of a pattern of five small yellow, green or orange circles, which is repeated across areas of the banknote at different orientations. www.bookrags.com /wiki/EURion_constellation   (642 words)

Euro banknotes | Topic Definition | Find the Meaning and Define the Answer of Euro banknotes   (Site not responding. Last check: 2007-11-04) EURion constellation: Euro banknotes contain a pattern known as the EURion constellation which can be used to detect their identity as banknotes to prevent copying. Infra-red and ultra-violet watermarks: when seen in the near infrared, the banknotes will show darker areas in different zones depending on the denomination. Ultraviolet light will make the EURion constellation show in sharper contrast, and also some fluorescent threads stand out. www.thefreeencyclopedia.com /definition/word.aspx?w=Euro_banknotes   (1359 words)

Hard-boiled Dreams of the World » Blog Archive » Find Constellations on your Money Coined the “EURion constellation” by computer security expert Markus G. Kuhn because he first noticed it on EURO notes, the EURion constellation consists of a pattern of five 1 mm circles. The constellation is arranged roughly the same as the astronomical constellation of Orion. The design details of the EURion constellation remain secret, although there must be at least a handful of people who know all about it due to the fact that so many copier machines (Xerox, etc.) and computer programs (Photoshop, Paintshop Pro, etc.) across the world detect the pattern. joecrubaugh.com /blog/2007/02/01/find-constellations-on-your-money   (424 words)

Steven J. Murdoch :: Software Detection of Currency "Eurion constellation" was used to identify banknotes in the newly deployed software based system, since this has been confirmed to be the technique used by colour photocopiers, and was both necessary and sufficient to prevent an item being duplicated using the photocopier tested. However further investigation showed that the detection performed by software is different from the system used in colour photocopiers, and the Eurion constellation is neither necessary nor sufficent, and in fact it probably is not even a factor. Another interesting property of this image is that it seems to be a near minimal test case, since if any changes are made, then it is no longer detected as currency. www.cl.cam.ac.uk /~sjm217/projects/currency   (922 words)

Liudvikas Bukys » Blog Archive » the EURion Constellation on banknotes On the 20 pound note, they appear as “notes” in an unlikely short music score, in the old German 50 mark note, they are neatly embedded into the background pattern, and in the new 20 dollar bill, they are used as the 0 of all the yellow 20 number printed across the note. The constellation are probably detected by the fact that the squares of the distances of the circles are integer multiples of the smallest one. I have later been told that this scheme was invented by Omron and that the circle patter also encodes the issuing bank. l.bukys.org /2004/01/14/the-eurion-constellation-on-banknotes   (389 words)

Urban Legends of Canadian Currency - The Coin Tree in Alberta, Canada   (Site not responding. Last check: 2007-11-04) The software was originally thought to be recognizing a pattern of five small yellow circles or dots that are scattered across many banknotes called the EURion constellation. These patterns discovered by Markus Kuhn in 2002 were named for their similarity to the Orion star constellation and for the Euro bank notes on which they were first discovered.

famous and nonfamous strangers: Digital currency detection What I find fascinating about this is the way that the banknote designers have incorporated the constellation into their designs. I have discovered a small constellation of just five circles (a bit like Orion with the belt starts merged) that will be rejected by a Xerox color photocopier installed next door from here as a banknote. I have later been told that this scheme was invented by Omron and that the circle pattern also encodes the issuing bank. www.nonfamous.com /blog/archives/000314.html   (556 words)

Computers: Beware of imitations by Russell Brown | New Zealand Listener   (Site not responding. Last check: 2007-11-04) 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. The EURion Constellation Kuhn looks at what’s hidden in the stars on European currencies. www.listener.co.nz /issue/3326/columnists/1412/beware_of_imitations.html   (835 words)

Canadian banknotes - FX Reserves   (Site not responding. Last check: 2007-11-04) These features are reliable, quick and easy to use, and are designed to help Canadians protect themselves from accepting counterfeit notes. All 2001 through 2005 series notes also include the EURion constellation, on both sides of the bill. The new bills have a "tactile feature", which is a series of raised dots (but not in Braille) in the upper right corner on the obverse of each bill to aid the visually impaired in identifying currency denominations. www.fxreserves.com /article/canadian_banknotes.htm   (909 words)

Canadian hundred-dollar bill Information The reverse also has a visible security feature: an interleaved metallic strip, reading '100 CAN' repeatedly along its length. Yellow dots representing the EURion constellation can be found on both sides (and on all 2001 series notes). As well as textured printing, this new 2004 design incorporates a special tactile feature similar to Braille dots for the blind indicating the denomination. www.bookrags.com /wiki/Canadian_hundred-dollar_bill   (500 words)

Ned Batchelder: January 2007 Turns out these numbers are part of the EURion constellation on the bill. The zeroes are circles in a specific geometric arrangement that allows for detection of moneyness (to coin a term, har!) by copiers and software like Photoshop, which refuses to open scanned images of money. The EURion constellation being part of the image seems not to be correlated to detection. www.nedbatchelder.com /blog/200701.html   (3307 words)

(GCNEP8) Con Currency by mlord   (Site not responding. Last check: 2007-11-04) One of the simplest of these is a pattern of five 1mm dots that is repeated in several places on each banknote. The arrangement of the five dots vaguely resembles the Orion star grouping, and has been dubbed "The Eurion Constellation" (after the Euro banknotes on which it was first noticed). For this cache, the posted coordinates represent the position of one of the dots of a single Eurion Constellation. www.geocaching.com /seek/cache_details.aspx?wp=GCNEP8   (637 words)

the null device A PDF document showing the "EURion constellation"; this is a constellation of five 1mm circles found on European and British banknotes, and recognised by colour photocopiers. (The piece doesn't show exactly which five circles are the constellation, though if it's there, it shouldn't be too hard to find it.) I'm not sure whether the pattern used on US banknotes (and now recognised by commercial image-processing software) is the same or different, or what other anti-copying patterns are used on other currency. Though if each country had its own, it would use a lot of CPU cycles to detect. dev.null.org /blog/archive.cgi/2004/01/13   (363 words)

Photoshop CS won’t do money at eclecticism   (Site not responding. Last check: 2007-11-04) In my book this is completely unacceptable - Photoshop is an image editor, not a censor, government policy enforcer or anything else. p>Further testing by users has determined that the limitation affects the new US $20 bill and several European bills, probably through as series of image-recognition algorithms (that, incidentally, must be applied to every image brought into Photoshop), at least one of which is probably the “EURion Constellation” method. Adobe has yet to comment on the issue. www.michaelhanscom.com /eclecticism/2004/01/09/photoshop-cs-wont-do-money   (537 words)

Two Brain Cells :: 2006 :: June It’s the EURion constellation, a standardised repeating pattern that can be detected by computer, and which is used in modern colour photocopiers to stop you from copying bank notes.

About the Music of Cuba - worldmusic.cc   (Site not responding. Last check: 2007-11-04) With the advance of forgery technology, the Bundesbank decided to introduce additional security features on the most important denominations (50, 100, and 200 DM) as of 1996. These were a hologram foil in the center of the note's obverse, a matted printing on the note's right obverse, showing its denomination (like on the reverse of the new €5, €10, and €20 banknotes), and the EURion constellation on the note's reverse. Furthermore, the colors were changed a bit to pastel to hamper counterfeing. www.worldmusic.cc /en/music/latin_america/cuba/698.html?title=German_mark   (2253 words)

Freedom to Tinker » Blog Archive » Photoshop and Currency (On the new U.S. $20 bills, they’re the zeroes in the little yellow “20″s that pepper the background on the back side of the bill.) Markus called the special five-dot pattern the “constellation EURion” because he first spotted it on Euro notes. But reported experiments by others show that Photoshop is looking for something other than EURion. For example, Jon Sullivan says that Photoshop refuses to load this image, which nobody would mistake for currency. www.freedom-to-tinker.com /archives/000497.html   (1653 words)
