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.... There were traitors in the most secret council-chambers. Generals, senators, and secretaries looked at each other with suspicious eyes.... It is a great wonder that the city of Washington was not betrayed, burned, destroyed a half-dozen times.”
—M. E. W. Sherwood (1826–1903)
“Our life is a faint tracing on the surface of mystery, like the idle, curved tunnels of leaf miners on the face of a leaf. We must somehow take a wider view, look at the whole landscape, really see it, and describe what’s going on here. Then we can at least wail the right question into the swaddling band of darkness, or, if it comes to that, choir the proper praise.”
—Annie Dillard (b. 1945)
