Hidden in Plain Sight.
Mysterion embeds cryptographic proof directly into your content — images, video, and batches. Invisible to the eye. Immutable to the record.
Verify images, videos, or batches — free, no account required
The Mechanism
Content speaks.
The proof is silent.
Every image or video published through Mysterion carries a hidden, tamper-evident signature — bound to your identity, verifiable by anyone, visible to no one. Only cryptographic hashes ever leave your device. Your content never does.
Select Your Content
Choose any image or video file. Everything that follows happens locally — your file never leaves your device.
Sign Locally
A cryptographic signature is invisibly embedded directly into the file — in the pixel data for images, in the bitstream for video. Nothing is re-encoded. Nothing is uploaded.
Publish with Confidence
Share it anywhere. The proof travels with the file — surviving compression, format conversion, and platform processing. Anyone can verify it. No upload required.
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.
Who It Protects
Trust is the product.
Content Creators
Prove your work is original the moment you publish. Protect against deepfakes, attribution theft, and content manipulation.
- Immutable attribution
- AI deepfake defense
- Licensing proof
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.
ML-DSA-87 Post-Quantum Signing
Your identity is the root of trust. Every signature uses ML-DSA-87 (FIPS 204) — a post-quantum algorithm that remains secure against both classical and quantum computers. Bound to an X.509 certificate chain. No third-party intermediary required. Ahead of CNSA 2.0 mandates by years.
Image, Video & Batch Processing
Signatures are woven directly into your content — invisible to the eye, present in every frame. Process single files or entire batches at once. No visual degradation. No separate sidecar file.
SDK & API First
Node.js, Python, and REST API. Integrates into existing publishing workflows in minutes. Chrome and Firefox extensions for on-the-fly verification.
C2PA Compliant
Fully implements the Coalition for Content Provenance and Authenticity standard. Interoperable with C2PA-enabled cameras, platforms, and toolchains out of the box.
Multi-Layer Tamper Detection
Verification runs multiple independent checks simultaneously. Any modification — however small — breaks the proof. There is no ambiguity in the result.
Multi-Platform Verification
Verify via web, browser extension, API, or mobile. One signature standard across every surface — one truth.
Creator Analytics & Content Intelligence
Every time signed content is verified anywhere on the web, the event is logged — anonymously. Creators see where their content traveled, what regions it appeared in, and which domains are hosting it without permission. Cryptographic proof meets distribution intelligence. Fully anonymized, no personal data collected.
Unauthorized Distribution Detection
If your content appears on a domain you never authorized, Mysterion knows. Verification events include the domain where content was encountered — giving creators timestamped, cryptographically-linked evidence for licensing disputes and takedown notices. No other platform provides this automatically.
Zero Data Custody — Your Files Never Leave Your Device
Signing happens on your device. Your content never touches our servers — only the cryptographic fingerprints that prove it. No breach exposure. No compliance entanglement. No exceptions. Learn how this works →
Ecosystem
Works with C2PA-enabled cameras.
Leading camera manufacturers now embed cryptographic provenance at the moment of capture. Mysterion will extend that chain — registering C2PA camera credentials and carrying the proof through editing, distribution, and beyond, where platform processing would otherwise strip it away. Video signing is live. Camera registration is available now.

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.

Scaled by someone who's run the global table.
30 years building, delivering, and closing across six countries — from mainframe code to multimillion-dollar signings. Arup Aditya joined Mysterion because trust infrastructure needs more than engineering. It needs someone who knows how enterprises buy, build, and bet.
