Content Watermarks (C2PA)

C2PA is an industry standard that adds an invisible 'this is real' or 'this was AI-made' label to images and videos.

Cameras from Sony, Nikon, and Leica add C2PA marks at capture. Adobe Firefly adds them to AI images. Browsers are starting to display them.

Three things C2PA does

Marks photos as camera-original or AI-made
Tracks edits so you see what was changed
Hard to remove without breaking the file

Key terms in this lesson

The big idea: C2PA is the new way to know if a photo or video is real or AI-made.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1Ask AI to explain C2PA in plain language, then underline anything that sounds uncertain or too broad.
2Give it one detail from "Content Watermarks (C2PA)" and ask for two possible next steps plus one reason each step might be wrong.
3Check provenance against a trusted source, teacher, adult, expert, or original document before you use it.
