Watermarking is described as which of the following?

• A. Process of encrypting data with a watermark key
• B. Process of superimposing a logo or text to a document or image file to aid copyright protection
• C. A method of encoding metadata in network packets
• D. A technique for rate-limiting traffic

Answer: (B)

Watermarking is about embedding a mark into content to indicate ownership and authenticity. By placing a visible logo or text on a document or image, the creator can prove copyright and track unauthorized use, even after copies are made. This mark can be visible or embedded in a way that’s not easily removed, serving as a persistent identifier of the source.

This differs from encryption, which hides the actual content by transforming it into unreadable data. It also isn’t about encoding metadata in network packets or rate-limiting traffic, which are unrelated concepts.
