They won&#8217;t tell what the algorithm is, but most folks guess that the algorithm is at least in part based on something called the <em>EURion Constellation<\/em>.<\/p>\n<p>The EURion Constellation is a grouping of objects which can be detected by a scanner or by photo-editing software like Photoshop. As the name implies, the grouping looks similar to everyone&#8217;s favorite star constellation, Orion. Here&#8217;s what the grouping looks like:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.wambooli.com\/blog\/wp-content\/uploads\/2010\/01\/150px-EURion.svg_.png\" alt=\"150px-EURion.svg\" title=\"150px-EURion.svg\" width=\"150\" height=\"150\" class=\"alignnone size-full wp-image-1060\" \/><\/p>\n<p>If you get a new $5, $10, $20, or $50 bill you&#8217;ll find items on the bill in the grouping shown above. If you have a $20 handy, look on the back and you&#8217;ll see the EURion grouping used on many of the teensy, golden &#8220;20&#8221; symbols on the left side of the bill.<\/p>\n<p>I suppose the grouping is found on all the bills, either that or Photoshop is using some other algorithm to detect currency.<\/p>\n<p>Curiously, the $100 bill doesn&#8217;t have this type of protection; scanning and editing a $100 bill in Photoshop apparently doesn&#8217;t pose a problem.<\/p>\n<p>Now, of course, I&#8217;m not encouraging you to copy currency. It is illegal. Then again, photo-editing your face onto a $50 bill is supposedly okay, but Photoshop will not let you print your efforts. So be it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ever try to scan in some currency and edit it in Photoshop?
