A more thorough explanation:

Definition: Copyright-management information refers to the name and other identifying information about the creator, performer, or copyright owner of a creative work. This information is important for protecting the rights of the owner and ensuring that the work is used appropriately.

Example: If you download a song from the internet, the copyright-management information might include the name of the artist, the title of the song, and the record label that owns the rights to the song.

Explanation: This information helps to identify who owns the rights to the song and how it can be used. If someone tries to use the song without permission, the copyright owner can use this information to take legal action.

Definition: The Digital Millennium Copyright Act (DMCA) is a federal law that was passed in 1998. The law helps to protect copyright owners and limit liability for internet service providers.

Example: The DMCA makes it illegal to create or distribute tools that are designed to bypass digital antipiracy measures. This means that it is illegal to create or distribute software that can be used to copy DVDs or other copyrighted materials.

Explanation: The DMCA helps to protect the rights of copyright owners by making it illegal to create or distribute tools that can be used to copy their work without permission. This helps to ensure that copyright owners are able to control how their work is used and distributed.
