In 1996, the World Intellectual Property Organization (WIPO) sponsored
a treaty under which participating countries would standardize treatment
of digital copyrights. One of the items of standardization was the
prohibition of altering copyright management information (CMI) that is
included with the copyrighted material. CMI is:

A.
Licensing and ownership information

B.
A listing of Public keys

C.
An encryption algorithm

D.
Product description information

Explanation:
The other answers are distracters. The WIPO digital copyright legislation
that resulted in the US was the 1998 Digital Millennium
Copyright Act (DMCA). In addition to addressing answer d, the
DMCAprohibits trading, manufacturing, or selling in any way that is
intended to bypass copyright protection mechanisms. It also
addresses Internet Service Providers (ISPs) that unknowingly support
the posting of copyrighted material by subscribers. If the ISP is
notified that the material is copyrighted, the ISP must remove the
material. Additionally, if the posting party proves that the removed
material was of lawful use, the ISP must restore the material and
notify the copyright owner within 14 business days.
Two important rulings regarding the DMCA were made in 2001.
The rulings involved DeCSS, which is a program that bypasses the
Content Scrambling System (CSS) software used to prevent viewing
of DVD movie disks on unlicensed platforms. In a trade secrecy case
[DVD-CCA v. Banner], the California Appellate Court overturned a
lower court ruling that an individual who posted DeCSS on the Internet
had revealed the trade secret of CSS. The appeals court has
reversed an injunction on the posting of DeCSS, stating that the code

is speech-protected by the First Amendment.
The second case [Universal City v. Reimerdes] was the first constitutional
challenge to DMCA anti-circumvention rules. The case
involved Eric Corley, the publisher of the hacker magazine 2600
MagazinE. Corley was covering the DeCSS situation and, as part of
that coverage, posted DeCSS on his publications Web site. The trial
and appellate courts both ruled that the posting violated the DMCA
and was, therefore, illegal. This ruling upheld the DMCA. It appears
that there will be more challenges to DMCA in the future.
