Another Pixel Idea — Tracking Dots on Everything You Print
This one will make you think.
The Electronic Frontier Foundation has found, and decoded, secret hidden “dots” that many color lasers are imprinting on every printed page.
Information includes the make and model of the printer as well as the exact time the printout was made.
No more “I finished the report last week and just forgot to give it to you.” Now, anyone who knows the code can see what printer you used and when you printed it.
Interesting!
Check out the story of how they cracked the code here. And see the current list of printers that do this here.
