    Eurion. nice funda.


  2. The title was a big clue. its the EURion constellation


  3. Copy from wiki :
    The EURion constellation is a pattern of symbols found on a number of banknote designs worldwide since about 1996. It is added to help software(Adobe Photoshop etc ) detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers.

    EURion constellation to help Colour Photocopiers and Photoshop like programs detect the presence of a banknote in a digital image.
    Prevents counterfeiting.

    Photoshop etc shows a “action not supported” dialog box, and prevents further processing.

    EURion Constellation. Helps preventing printing of currency notes using Photoshop or ordinary printers.

    EURion constellation. A pattern of symbols found on banknotes.
    Err, but apparently Photoshop and other software do not rely upon this pattern to detect banknotes but rather looks for a digital watermark embedded on the notes.

    EURion constellation.
    EURion constellations are found in currency notes and while using image editors like Adobe Photoshop,we find that software refuses to print the image if such patterns are found in image.


  13. eurion
    when photoshopped..it gives out an error message…unauthorised editing of notes


  14. Inglourious

    Eurion constellation or Omron rings. Digital imaging softwares and color printers do not allow printing images which contain such rings.

    The EURion constellation, used to detect counterfeit currency.

    Photoshop refuses to print such notes, but Wiki says it’s not really because of the constellation, but other digital watermark detection thingies.

    The pattern is called “EURion constellation”.

    Though banknote detection code in these applications, called the Counterfeit Deterrence System (CDS),
    are supplied to companies such as Adobe, experiments have shown that this banknote detection code does not rely on the EURion pattern.
    It instead detects a digital watermark embedded in the images.


  38. EURion constellation. Adobe Photoshop doesn’t print a document that has these patterns.

    Pattern of symbols found on some currencies of some countries. After 1996 many countries followed this.
