C2PA and Content Credentials Quiz

Answers and explanations appear as you take the quiz.

1. What is a C2PA manifest?
   • A hidden watermark embedded in pixels
   • A cryptographically signed record of a file's origin and edits
   • An AI model that detects deepfakes
   • A list of banned images
2. Which statement about missing Content Credentials is correct?
   • It proves the file was AI-generated
   • It proves the file was edited illegally
   • It means the camera was broken
   • It proves nothing, because most files lack credentials and many platforms strip them
3. What does a valid C2PA signature actually establish?
   • Who signed a claim about the content, and that the file matches what was signed
   • That the scene depicted really happened
   • That the content contains no AI
   • That the image has never been cropped
4. How does watermarking such as SynthID differ from C2PA?
   • Watermarks are signed with X.509 certificates
   • C2PA is invisible and inside pixels
   • A watermark hides a signal in the content itself, while C2PA stores a detailed history in metadata that can be removed
   • They are identical technologies
5. What is the hard binding in a C2PA claim?
   • A cryptographic hash of the asset's bytes, excluding the region where the manifest is stored
   • A physical lock on the camera
   • A watermark in the image
   • The creator's password
6. What purpose do soft bindings serve?
   • They replace digital signatures
   • They compress the image
   • They block screenshots
   • They let a validator recover a remotely stored manifest after metadata is stripped
7. Which organizations founded C2PA in 2021?
   • Only Google and OpenAI
   • Adobe, Arm, the BBC, Intel, Microsoft and Truepic
   • The FCC and the FTC
   • Leica, Sony and Nikon alone
8. What are ingredients in a C2PA manifest?
   • Chemical data about camera sensors
   • Encryption keys for the file
   • Source assets, with their own manifests, that were combined into the file
   • Advertising tags
