Traitor tracing is a copyright infringement detection system which works by tracing the source of leaked files rather than by direct copy protection. The method is that the distributor adds a unique salt to each copy given out. When a copy of it is leaked to the public, the distributor can check the value on it and trace it back to the "leaker".

Famous quotes containing the words traitor and/or tracing:
“... what a strange time it was! Who knew his neighbor? Who was a traitor and who a patriot? The hero of to-day was the suspected of to-morrow....

It is a great wonder that the city of Washington was not betrayed, burned, destroyed a half-dozen times.”

“And if anyone should think I am tracing this matter too curiously, I, who have considered it in various shapes, can only answer with Hamlet ... “Not a jot”; it being no more than the natural result of examining and considering the subject.”
