Hidden in Plain Sight.
Mysterion embeds cryptographic proof directly into your content. Invisible to the eye. Immutable to the record.

The Mechanism
Content speaks.
The proof is silent.
Every image, video, or document published through Mysterion carries a hidden, tamper-evident signature — bound to your identity, verifiable by anyone, visible to no one.
Create or Upload
Submit any digital asset — photo, video, document — through the Mysterion SDK or web interface.
Embed the Signature
A cryptographic signature from your x.509 certificate is invisibly woven into the file's pixel data — imperceptible to the human eye.
Publish with Confidence
Share it anywhere. The proof travels with the file — surviving compression, format conversion, and platform processing.
What any verifier sees — a clean, trustworthy proof of origin.
Provenance chain is intact.
Verified by Mysterion
was modified after signing.
Content Altered
AI-generated likeness detected.
Synthetic Detected
Origin & integrity unverifiable.
Unknown Origin
Hover each card to see what the state means. Mysterion makes every answer verifiable.

Consumers
Scan any image or video to instantly verify who made it, when, and whether it's been altered. Trust what you see.
- One-tap verification
- Source transparency
- Manipulation detection
The Architecture
Built for production.
Designed for scale.
X.509 PKI Integration
Binds every signature to a verified certificate chain. Your identity is the root of trust — no third-party intermediary required.
LSB Steganography
Signatures live in the least-significant bits of pixel data. Perceptually invisible. Cryptographically verifiable. Survives most post-processing.
SDK & API First
Node.js, Python, and REST API. Integrates into existing publishing workflows in minutes. Chrome extension for on-the-fly verification.
C2PA Compliant
Aligns with the Coalition for Content Provenance and Authenticity standard, ensuring interoperability with major platforms and toolchains.
Tamper Detection
Any modification to signed content — even a single pixel — breaks the cryptographic proof. Alterations cannot go undetected.
Multi-Platform Verification
Verify via web, browser extension, API, or mobile. One signature standard across every surface — one truth.

The Founder
Built by someone who's been in the infrastructure.
36 years in network security. A math major who started at a helpdesk in 1990 and spent three decades building the systems organizations depend on. Chris Hallman founded Mysterion because he saw where generative AI was headed — and knew the infrastructure for trust wasn't ready.
