Title 17 › CHAPTER 12 — COPYRIGHT PROTECTION AND MANAGEMENT SYSTEMS › § 1201
Makes it illegal to break or bypass digital locks that control access to copyrighted works, starting at the end of the 2-year period after this law was enacted. It also bans making, importing, selling, or providing tools that are mainly meant to break those locks, that have little other real use, or that are marketed for that purpose. The Librarian of Congress must review classes of works during the first 2 years and then every 3 years to see if users would be harmed by the ban; any class the Librarian exempts will be free from the ban for the next 3 years. The rule does not change copyright defenses like fair use or change other liability rules. The law gives short one-line meanings for some terms: "circumvent a technological measure" means avoiding, removing, or bypassing a digital lock without the owner’s permission; a technological measure that "effectively controls access" means a lock that normally needs owner-approved information or steps to get in; "circumvent protection" refers to actions that stop a lock from protecting a copyright owner's rights. It also lists exceptions: nonprofit libraries, archives, and schools may temporarily bypass locks to decide whether to buy a work (only if no other copy is reasonably available and only for that decision); authorized law enforcement and government information-security work is allowed; reverse engineering and interoperability work is allowed when done lawfully and only to make independent programs work together; good-faith encryption research and authorized security testing are allowed under limits and review. The Librarian and Commerce must report to Congress within 1 year on the encryption-research rules. There is a privacy exception that allows disabling a lock that secretly gathers personally identifying data without notice, if the only effect is stopping that data collection and no other law is broken. Special rules for analog video devices take effect 18 months after enactment and include sales-based triggers (1,000 Beta units and 20,000 certain 8mm units) and immediate limits on redesigned models.
