STEP 01
Create or import
Generate with a verified MEGGA clone, or bring your own content into the pipeline. Provenance starts at the source — not bolted on afterward.
MEGGA Shield
The proof layer for AI content.
Identity, provenance and compliance — sealed into every generation, and verifiable by anyone. Three open standards, one public certificate. Built for the EU AI Act.
Standards-based, publicly auditable
Three open standards converge into a single public certificate per generation.
C2PA Content Credentials. Adobe TrustMark. RFC 3161 timestamping. Anyone can verify a Shield certificate — without authentication, privileged access, or cooperation from us.

Architecture
Three pillars. One verifiable certificate.
Provenance
Cryptographic signature, invisible watermark, perceptual hash — sealed into every generation, so origin travels with the content.
Identity
Every clone is anchored to a verified creator. KYC, KYB, face match — enforced before training, not after.
Compliance
EU AI Act, GDPR, FTC AI Endorsement — compliant by construction, not by retrofit.
Live verification
Two ways to protect. One survives the real world.
Both modes seal provenance into a generation. Re-upload it to a social platform — which strips metadata and re-encodes the pixels — and the difference shows.

Illustrative — wired to MEGGA's live verification API, switching to real per-sample results once demo certificates are connected. The key point is structural: the invisible watermark lives in the pixels, so it survives the re-encoding that strips metadata.
Why it holds up
Built differently from likeness crawlers.
Monitoring tools guess: they crawl the web and run probabilistic face-matching on content they never made. Shield knows: because we generate the content, the proof is planted at the source.
| Approach | Probabilistic monitoring tools | MEGGA Shield |
|---|---|---|
| DetectionHow a match is made | Probabilistic face-match — false positives are inherent | Deterministic signal planted at creationRead back exactly — zero false positives |
| Reference | Scraped or user-uploaded photos | KYC-verified, consented identity |
| Provenance & proof | None | C2PA + RFC 3161 certificate + on-chain anchor |
| Survives re-encoding | Re-detect, best effort | Invisible watermark survives crop / JPEG / social |
| Regulatory grade | — | EU AI Act Article 50 by default |
| Privacy | Passive web & metadata harvesting | No location / EXIF harvesting by design |
Web-scale monitoring & takedown crawling is on our roadmap — today Shield's edge is provenance, identity and robustness: the layers a crawler structurally cannot add after the fact.
End to end
Build the proof. One click at a time.
This is the exact chain Shield runs on every asset. Seal each layer yourself — from creation to the day it's contested.

STEP 02
Certify against a verified identity
Every asset is bound to a real, verified creator — KYC for individuals, KYB for brands, consent confirmed before anything is trained. Then the full Shield stack is sealed into the file.
STEP 03
Notarize on Polygon
The certificate's fingerprint is registered on the Polygon blockchain (mainnet) — a public, immutable, independently verifiable record of origin and ownership. Anchored asynchronously, so issuing the certificate is never blocked.
STEP 04
Verify anywhere
Anyone — a platform, a regulator, a journalist, a buyer — reads the certificate against open standards, with no login and no cooperation from us. The proof travels with the content.
STEP 05
Monitor, map & enforce
Shield keeps watching: it tracks where your certified content travels, maps how your audience engages with it, and turns confirmed misuse into automated takedown claims — backed by a tamper-evident, enforceable evidence trail.
