Sen. Joseph Biden (D-DE) has introduced a bill (S. 2227) that would make it illegal to traffic in "illicit authentication features." Authentication features help companies determine that an item is not counterfeit; illicit authentication features would be intended to facilitate illegal copying of movies, music, or computer programs. Such a feature would also be a genuine authentication feature that has been distributed without authorization from the copyright owner. A copyright owner could file a civil lawsuit against the perpetrator.
