@douginamug That is how whistleblower Reality Winner was identified and arrested.
@joachim damn. And to think I had no idea I was producing these dots myself til last week!
@jums @douginamug @joachim
There's a US FOIA answer with a list of manufacturers that include these, and it's ...basically all of them ;) since we're on this topic, if you want to add dots to your document for fun, use these: https://en.wikipedia.org/wiki/EURion_constellation :P
@krugar @joachim @douginamug @jums there's a lot of fuzziness there. For some printers there is a concrete "yes" to the #trackerdots question, and for others it's up in the air. Obviously ppl should avoid buying a printer that's confirmed compromised. Oki is a good bet. It's non-US, & Oki doesn't have scandals and dirt that most makers have.
@jums @douginamug @joachim @krugar This is where some of my info comes from: https://www.eff.org/pages/list-printers-which-do-or-do-not-display-tracking-dots
@joachim @douginamug It's interesting that the dots were readable on The Intercept's *published version* of the documents, which seems to imply they did a really high quality color scan, no? Who does that? Why wouldn't a newspaper be smart enough to scan (presumably text) docs as a bitonal image where a yellow dot would be assigned white and not black?
