Las respuestas y explicaciones aparecen a medida que realiza el cuestionario.

  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
    • Comprimen la imagen
    • 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
