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:
“Man is exceedingly well defended against himself, against being scouted out and besieged by himself, and he is usually able to make out no more of himself than his outer fortifications. The actual fortress is inaccessible to him, even invisible, unless his friends and enemies turn traitor to him and lead him there by secret paths.”
—Friedrich Nietzsche (1844–1900)
“Lexicographer: a writer of dictionaries, a harmless drudge, that busies himself in tracing the original, and detailing the signification of words.”
