C2FA LocalExperimental source preview
Experimental source preview

Local-first media integrity evidence for files and available C2PA metadata.

C2FA helps inspect file-level integrity signals, C2PA manifest availability, validation status, and local evidence exports without uploading files to a hosted analysis service.

C2FA verifies file-level integrity evidence and available C2PA-related metadata. It does not prove that media content is true or authentic.

Experimental source preview — not production-ready.

What C2FA does

Local file analysis

Analyses a selected file in the local app flow without a hosted upload service.

Validator status visibility

Surfaces validator-backed readiness and runtime state in a simple operator view.

C2PA manifest status

Shows whether the file has a manifest, lacks one, or cannot be read by the current path.

Human-readable evidence summary

Turns technical output into a readable explanation layer for review.

Technical JSON evidence

Preserves the structured JSON needed for deeper inspection and handoff.

Receipt/report JSON export

Exports local evidence records for audit, review, and operator workflows.

What C2FA does not do

Does not prove physical-world truth

Evidence signals are not proof of what happened in the physical world.

Does not guarantee authenticity

Validation is a signal, not an authenticity guarantee.

Does not claim full C2PA coverage

Coverage remains intentionally scoped and should not be overstated.

Does not upload files to a hosted analysis service

The public site is informational only and does not accept file uploads.

Is not production-ready

This is a preview surface, not a production service claim.

Is not certification

No certification or official verifier status is implied.

Result meanings

verified

Validator-backed C2PA validation status, not physical-world truth.

not_present

No C2PA manifest detected.

invalid

C2PA data was present but validation failed.

error / unsupported

The current validator path could not analyze the file.

Local-first privacy model

C2FA is designed for local/private pilot usage. The public landing page is informational, and the local app flow is where files are analyzed.

  • Designed for local/private pilot usage.
  • Files are analyzed locally in the local app flow.
  • The public landing page does not upload or analyze files.
  • No account system in the landing MVP.
  • No analytics or telemetry.

Public source preview

A public-safe source preview is available and excludes private pilot history, internal evidence artifacts, and private core repo material.
