The Librarian of Congress has published the fifth triennial set of rules on exemptions from the “anticircumvention provision” of the Digital Millennium Copyright Act. There are now five categories that allow interested parties to legally “circumvent” digital rights management schemes. Exceptions include the ability to “crack” for certain purposes motion pictures made available on DVD or online, to “jailbreak” and “unlock” phones, and to access e-books to enable functions crucial to persons with disabilities. The published exceptions are one fewer than the previous set, as the video game security research exception was eliminated, and six fewer than the proposed exceptions. The new rules became effective on October 28, 2012, and are valid until 2015.
