Which term refers to embedding a unique marker into a file to prove ownership of a digital asset?

• A. Watermarking
• B. Policy Template
• C. Document Matching
• D. DRM

Answer: (A)

Watermarking involves embedding a marker into a digital asset to prove ownership. This marker can be visible, like a logo or text superimposed on an image, or invisible, embedded in the data so it’s not easily noticed but can be detected later. The purpose is to tie the work to a specific owner or license and to provide evidence of authorship or rights if the asset is shared or distributed without permission. A watermark should be robust enough to survive common edits or compression so ownership proof remains verifiable even after modifications. This concept is distinct from DRM, which is about restricting how content can be used; policy templates define rules, and document matching is about comparing documents, not marking ownership within the asset.
