Yellow dots

Author: Banana | Filed under: Sicherheit
Tja, wer hätte das gedacht.
Als Kontrollmechanismus erdacht, als Lösung in einem Rätsel der Kontrolleure verwendet.

In October, Darpa offered $50,000 to the first group to piece together the shredded documents or the one that made the most progress by Dec. 4.

Und nun rater mal wie das Rätsel gelöst wurde ?

Then he happened on an article about a little-known government project: The U.S. Secret Service has been working with manufacturers of color laser printers to place tiny, imperceptible yellow dots on printed pages so that the government can track the machine that produced them.

Ja, richtig. Mit einer Methode die eigentlich nicht dafür gedacht war ;-)
