The WIPO Copyright and Performances and Phonograms Treaties Implementation Act, is a part of the Digital Millennium Copyright Act (DMCA), a 1998 U.S. law. It has two major portions, Section 102, which implements the requirements of the WIPO Copyright Treaty, and Section 103, which arguably provides additional protection against the circumvention of copy prevention systems (with some exceptions) and prohibits the removal of copyright management information.
