The manifest carries a machine-readable provenance trail (who generated it, what generator was used, what prompt produced it, when it was reviewed) plus a visible AI-generation claim in the IPTC digital-source-type vocabulary.\n\nThis is the technical mechanism brands use to comply with:\n\n- **EU AI Act Article 50** (applicable 2 August 2026) — generative-AI marketing content must be marked in a machine-readable format using open, interoperable standards. C2PA is the emerging backbone. Penalty for non-compliance: up to **€15 million or 3% global annual turnover**.\n- **NY synthetic-performer disclosure law** (effective June 2026) — $1K–$5K per violation, $10K repeat; applies to synthetic influencers and AI-generated endorsements.\n- **FTC May 2026 endorsement guidance** — covers AI testimonials and synthetic creator content.\n- **Australia Online Safety Act / UK Online Safety Act** — emerging deepfake disclosure requirements.\n\nThe resulting asset can be inspected by any C2PA-aware viewer (Adobe Photoshop, Lightroom, Truepic, [contentcredentials.org/verify](https://contentcredentials.org/verify)).\n\n### C2PA spec versions to be aware of (June 2026)\n\n- **Content Credentials 2.3** (released 9 February 2026 — [launch post](https://c2pa.org/the-c2pa-launches-content-credentials-2-3-and-celebrates-5-years-of-impact-across-the-digital-ecosystem/)) added format support for: **live video** (broadcast/streaming), **plain text documents**, **OGG Vorbis audio**, **large AVI video files**, and **EXIF Original Preservation Images**. If a brand is signing live-stream video or text-based assets for the first time, 2.3 is the floor version to target.\n- **C2PA Spec 2.4** (April 2026 — [spec.c2pa.org/specifications/specifications/2.4](https://spec.c2pa.org/specifications/specifications/2.4/specs/C2PA_Specification.html)) introduces the **AI Disclosure Assertion (`c2pa.ai-disclosure`)** for machine-readable AI transparency info — this is the assertion the EU AI Act Article 50 deployer pathway will rely on. The final Code of Practice on Transparency of AI-Generated Content (published 10 June 2026) references C2PA-style assertions as the canonical machine-readable marking mechanism for both providers and deployers. See `skills/context-engine/eu-code-of-practice.md` for the full Article 50 context.\n- The **C2PA Trust List** is now handled via the public C2PA Conformance Program (any CA meeting the Certificate Policy can join). Production signing certificates should come from a Conformance-Program-listed CA, not an ad-hoc cert.\n\n**For DMP outputs**: `embed-c2pa.py` now supports `--ai-disclosure`. Pass it to embed the C2PA 2.4 `c2pa.ai-disclosure` assertion alongside the existing IPTC digital-source-type claim. The combination gives you both human-readable (IPTC) and machine-readable (`c2pa.ai-disclosure`) EU AI Act **Article 50** signaling — this is the deployer-side machine-readable pathway the final Code of Practice (10 June 2026) points to as the canonical marking mechanism. See `skills/context-engine/eu-code-of-practice.md` for the full Article 50 context.\n\n## When to invoke\n\n- Right after any AI image / video / audio generation step in the engagement workflow (Part 11 — AI Creative Instructions output)\n- Before handing a generated asset to the design team for review\n- As a pre-publish gate in `/digital-marketing-pro:check` for EU-targeted assets\n- Bulk-applying to a backlog of AI-generated assets before EU AI Act enforcement on 2 Aug 2026\n\n## Quick examples\n\n```bash\n# Single asset — image generated by Vertex AI / Nano Banana Pro\n/digital-marketing-pro:c2pa-metadata \\\n    --input assets/q3-launch-hero.png \\\n    --output assets/signed/q3-launch-hero.png \\\n    --brand \"Acme Corp\" \\\n    --generator \"Vertex AI / Nano Banana Pro\" \\\n    --ai-claim ai-generated-content \\\n    --prompt \"minimalist product hero shot, soft natural lighting\"\n\n# Video with human review tracked\n/digital-marketing-pro:c2pa-metadata \\\n    --input campaigns/launch-video-v3.mp4 \\\n    --output campaigns/signed/launch-video-v3.mp4 \\\n    --brand \"Acme Corp\" \\\n    --generator \"Runway Gen-4\" \\\n    --ai-claim ai-generated-content \\\n    --reviewer \"Jane Smith\"\n\n# EU-targeted asset — add the machine-readable Article 50 AI-disclosure assertion (C2PA 2.4)\n/digital-marketing-pro:c2pa-metadata \\\n    --input assets/q3-launch-hero.png \\\n    --output assets/signed/q3-launch-hero.png \\\n    --brand \"Acme Corp\" \\\n    --generator \"Vertex AI / Nano Banana Pro\" \\\n    --ai-claim ai-generated-content \\\n    --ai-disclosure \\\n    --prompt \"minimalist product hero shot, soft natural lighting\"\n\n# Human-created image with AI-assisted edits\n/digital-marketing-pro:c2pa-metadata \\\n    --input assets/founder-headshot-edited.jpg \\\n    --output assets/signed/founder-headshot-edited.jpg \\\n    --brand \"Acme Corp\" \\\n    --generator \"Adobe Generative Fill\" \\\n    --ai-claim ai-assisted-edits\n\n# Production sign with a real C2PA signing certificate\n/digital-marketing-pro:c2pa-metadata \\\n    --input assets/q3-launch-hero.png \\\n    --output assets/signed/q3-launch-hero.png \\\n    --brand \"Acme Corp\" \\\n    --generator \"Vertex AI / Nano Banana Pro\" \\\n    --ai-claim ai-generated-content \\\n    --signing-cert /secure/c2pa-prod-cert.pem \\\n    --signing-key /secure/c2pa-prod-key.pem\n```\n\n## AI claim values (IPTC digital source type)\n\n| Value | When to use | Maps to IPTC URI |\n|---|---|---|\n| `ai-generated-content` | Asset fully generated by AI | `algorithmicMedia` |\n| `ai-assisted-edits` | Human-created + AI-edited (e.g. Generative Fill) | `compositeWithTrainedAlgorithmicMedia` |\n| `ai-no-substantive-changes` | AI used (e.g. upscaling) but no semantic change | `minorHumanEdits` |\n\nThe IPTC vocabulary is what EU AI Act regulators reference — using these values rather than ad-hoc strings makes the asset interoperable with the Article 50 enforcement tooling.\n\n## Supported asset formats\n\n`.png` · `.jpg/.jpeg` · `.webp` · `.gif` · `.tiff` · `.mp4` · `.mov` · `.webm` · `.mp3` · `.wav` · `.pdf`\n\n## Signing certificate\n\nProduction C2PA signatures require a certificate from a CAI-recognized signing authority. The script will use one if you pass `--signing-cert` and `--signing-key`. If you omit them, the script generates a **self-signed 90-day dev certificate** for development testing only — a self-signed asset will verify as \"signature present but signer not in trust list\" at [contentcredentials.org/verify](https://contentcredentials.org/verify).\n\nFor production deployment:\n\n1. Obtain a C2PA-compatible signing certificate from a CAI-recognized authority (Adobe, Truepic, Numbers Protocol, Microsoft Azure Confidential Ledger).\n2. Store the cert + key securely (do NOT commit to git; use an environment-variable path or secret store).\n3. Pass `--signing-cert` and `--signing-key` on every production invocation.\n\nReference: [opensource.contentauthenticity.org/docs/manifest/signing-manifests/](https://opensource.contentauthenticity.org/docs/manifest/signing-manifests/)\n\n## Python dependencies\n\n- `c2pa-python>=0.5.0` — auto-installed on first run via `pip install`\n- `cryptography` — only needed for the dev self-signed cert path; auto-installed if missing\n\nBoth are part of the plugin's **Full mode** (~50 MB) — see `pip install -r scripts/requirements.txt` in the README.\n\n## Output\n\nThe script prints a JSON status report to stdout:\n\n```json\n{\n  \"status\": \"success\",\n  \"input\": \"assets/q3-launch-hero.png\",\n  \"output\": \"assets/signed/q3-launch-hero.png\",\n  \"size_bytes\": 482371,\n  \"brand\": \"Acme Corp\",\n  \"generator\": \"Vertex AI / Nano Banana Pro\",\n  \"ai_claim\": \"ai-generated-content\",\n  \"created\": \"2026-05-16T10:30:00+00:00\",\n  \"manifest_assertions\": [\"c2pa.actions\", \"stds.schema-org.CreativeWork\"],\n  \"using_dev_cert\": false,\n  \"verify_url\": \"https://contentcredentials.org/verify\"\n}\n```\n\n## Integration with the engagement workflow\n\nIn a full 12-part engagement, this skill plugs in at **Part 11 — AI Creative Instructions output**. After a creative brief is rendered as an actual asset (by your creative tooling or a manual creative process), the resulting file passes through `c2pa-metadata` before being checked in to `engagements/<slug>/11-creative-briefs/signed/`.\n\nThe `/digital-marketing-pro:check` pre-publish gate should also verify that all AI-generated assets in an EU-targeted campaign carry a C2PA manifest. v3.4 adds this verification to the EU jurisdiction rule pack in `skills/context-engine/compliance-rules.md`.\n\n## Related\n\n- `/digital-marketing-pro:check` — pre-publish quality gate (now verifies C2PA manifest on AI assets for EU campaigns)\n- `skills/context-engine/compliance-rules.md` — EU AI Act Article 50 rule pack\n- `skills/influencer-creator/ftc-compliance.md` — FTC endorsement disclosure requirements\n- [C2PA Specification 2.4 (April 2026)](https://spec.c2pa.org/specifications/specifications/2.4/specs/C2PA_Specification.html) — defines the `c2pa.ai-disclosure` assertion (Article 50 machine-readable pathway); [Content Credentials 2.3 launch (Feb 2026)](https://c2pa.org/the-c2pa-launches-content-credentials-2-3-and-celebrates-5-years-of-impact-across-the-digital-ecosystem/)\n- [Content Authenticity Initiative](https://contentauthenticity.org/)\n","tagline":"Embed a C2PA provenance manifest into an AI-generated marketing asset (PNG, JPG, WebP, GIF, TIFF, MP4, MOV, WebM, MP3, WAV, PDF) via scripts/embed-c2pa.py — produces a signed copy of the file carrying IPTC digital-source-type AI claims, an optional c2pa.ai-disclosure assertion fo","category":"security","tags":["agent-skill"],"author":"indranilbanerjee","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github fast track","sourceDetail":"indranilbanerjee/digital-marketing-pro","creatorName":"indranilbanerjee","creatorUrl":"https://github.com/indranilbanerjee","sourceUrl":"https://github.com/indranilbanerjee/digital-marketing-pro/tree/main/skills/c2pa-metadata","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/indranilbanerjee-c2pa-metadata#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
