Prove every photo and video you publish is real.
Verimago publisher certificates give your newsroom cryptographic proof of authenticity. Let your audience tell your real content from deepfakes — instantly.
Trusted by leading newsrooms
From application to certified in days
The same chain-of-trust model as Extended Validation SSL — applied to media authenticity.
Apply and get verified
Submit your organization details. We verify editorial independence, domain ownership, and jurisdiction — typically within 5 business days.
Attended key ceremony
A witnessed Ed25519 keypair generation ceremony is conducted. Your private key is sealed in an HSM and your certificate is issued to the Verimago CA chain.
Integrate signing
Connect the Verimago signing API or camera app to your publishing workflow. Sign photos and videos at capture — metadata, timestamp, and your certificate are embedded.
Audience verification
Anyone can verify your media at registry.verimago.io or via the Verimago API. Your certificate and the media's integrity are verifiable in seconds.
Everything your newsroom needs
A complete certificate infrastructure — from key ceremony to audience verification.
HSM-backed Ed25519 keys
Your private key is generated in a witnessed ceremony and sealed in a FIPS 140-2 Level 3 hardware security module. It never leaves the HSM — not even Verimago can access it.
Sign at capture
The Verimago camera app and signing API create a cryptographic manifest the moment a photo or video is captured or published — before any edits or deepfake attempt.
Public registry
Every signed piece of media gets a permanent, auditable manifest at registry.verimago.io. Your audience can verify authenticity in seconds — no app required.
UGC corroboration
Automatically corroborate user-generated content using our 4-signal engine: geolocation, temporal metadata, OSINT cross-reference, and cryptographic hash matching.
API + SDK
Integrate signing and verification into your CMS, publishing workflow, or mobile app with our REST API and the @verimago/sdk for Node.js and Python.
Audit trail
Every certificate operation is logged to a tamper-evident audit trail — key ceremonies, signings, revocations, and verifications — for your compliance and legal teams.
Publisher certificate: $1,199/year
Includes the key ceremony, unlimited media signing, public registry listing, UGC corroboration engine, and API access. Or pay $749 per 6 months.
