How your printer may be spying on you
Posted on 22 October 2008, at 9:47 pm, by Wayne Schulz
Here’s an interesting item not everyone is aware of. According to the Electronic Frontier Foundation your color laser printer may be secretly encoding all of your printed documents with information like your printer’s serial number, time and date printed and brand of printer. This encoding appears under microscopic or blue light examination as tiny yellow dots. According to the Electronic Frontier Foundation there’s no law on the books requiring printer manufacturers to encode this information. Watch this YouTube video to see some samples of the yellow dot patterns on paper. And the next time you write a ransom note — use pencil and paper.

Haha, okay, for ransom notes I see the issue XD. But otherwise, this seems kind of like cameras that tag the time taken and camera it was taken with to photo’s exif data (or whatever it is)… useful, not bad! as long as we can’t see it (so it doesn’t ugly up a pretty document).
