The EURion Constellation is a pattern of symbols that make it difficult to scan or photograph banknotes and import it into Photoshop.

enter image description here

From Wikipedia

I am interested in understanding how this system works, and how single users could design patterns of symbols that Photoshop would not be able to import.

From what I have gathered online, the pattern itself is detected by Photoshop, so I am assuming that a user couldn't design their own pattern to protect their work individually.

But is there a way to reuse the already existing pattern in a graphical document to block a user from opening an image that contains it?

Disclaimer: I am not asking to reveal trade secrets regarding the making of money and I am not asking about counterfeiting techniques. I am asking about using a technology to do more copy protection than it was designed to do.

    Except photoshop does not react to EURion but a digimark watermark – joojaa Jun 15 '18 at 17:33
  • I'm confused I thought the name of this digital watermark was "EURion constellation". The first two sentences in the wikipedia article say that. – MicroMachine Jun 15 '18 at 17:36
  • The constellation has no name as far as we know it its called "Omron anti-photocopying feature" but the warning is supposedly based on digimark which is a different thing. In reality we dont know. In any case i can still edit the banknote just not in PS. Which isn't much of a impediment – joojaa Jun 15 '18 at 17:39
  • Who's "we"? 😉 The point of this question is to get to the bottom of things... Here's Digimarc (with a C)'s page on this. – MicroMachine Jun 15 '18 at 20:01
  • "we" is all of the poeople not in the know – joojaa Jun 15 '18 at 20:20
