Manifest vs. Latent: A Developer's Guide to SB 942 Disclosure Types

Visible vs. Invisible: The developer's guide to AI content labeling. 🏷️

Two Types of Disclosure

SB 942 distinguishes between "manifest" (visible) and "latent" (invisible) disclosures. You need both.

Manifest Disclosure

This is for the human eye. It must be:

  • Permanent: Hard to remove.
  • Clear: Understandable by a layperson (e.g., "AI Generated").

Latent Disclosure

This is for the machine. It involves embedding metadata into the file header.

  • Standard: Use C2PA.
  • Information: It should include the name of the tool and the date of generation.

Conclusion

Don't rely on just one. A watermark can be cropped; metadata can be stripped. Redundancy is key to compliance.
