Print signatures

There have been some interesting articles about printer signatures in the news recently. Apparently, there are these invisible dots that you can see with a blue light. The dots tell the person who can read the code the serial number of the computer and the date and time at which the document was printed. Any idea how this works? Also, do you know how I could print things in this invisible ink because it would be COOL to give people invisible messages.
