Lukáš Raynor Majer Posted June 8, 2020 Share Posted June 8, 2020 (edited) Hello, we all know that we are spied and all papers from our printers contains secret yellow dots code. I detected them in document printed on my printer and scanned on 1200 DPI scanner. I attached pictures. That big one with green surface is best to be viewed on big monitor with high resolution (I have 5K iMac). That dark one scan is detailed view on yellow dot on white paper (1000% zoom). My question to Affinity Photo pros: Can you please tell me what is the best way to detect these dots on paper via Affinity Photo? On Mac or iPad. Thanks.

It sounds like conspiracy theory to me. Not scary at all. This just looks like noise to me. Use a good deNoise processor, starting with the one in Photo.

John Rostron Posted June 9, 2020 Share Posted June 9, 2020 Well, I live and learn. Doesn't sound all that secret though, or even scary.

Yes, this is one of the ways how FBI / NSA identifies leaked documents. But they apply these tracking codes to ALL printers.

But they apply these tracking codes to ALL printers. Even the Electronic Frontier Foundation (EFF) says there is no way to know if so-called "tracking dots" or other forensic markings are created by all printers, or which agencies of which governments or other entities could decode them. Besides, if they are applied, to track anything requires at least temporary physical access to the printout itself.
