Share Anywhere
Post it. Screenshot it. Play it out loud. Re-upload it. The invisible watermark survives compression, cropping, and format conversion. The proof travels with the media.
Verify Anytime
Upload the media to ZRY or look it up in the public trust ledger. Every signed asset is recorded with tamper-resistant provenance. Anyone can verify independently—no original file required.
Built for Scale and Regulation
Enterprise-grade security and compliance. Designed for legal, regulatory, and platform-level trust.
Invisible Watermarks
Embedded at the frequency level so they survive screenshots, cropping, compression, and playback.
Cryptographic Proof of Origin
Each asset is signed with a tamper-resistant manifest that proves who created it and when.
C2PA Compatible
Fully compatible with C2PA. Signed provenance manifests integrate with existing trust infrastructure.
Post-Quantum Cryptography
ML-DSA signatures and ML-KEM key encapsulation. Future-proof against quantum computing threats.
Public Trust Ledger
Every signed asset is recorded. Anyone can look up provenance and verify authenticity—without contacting the signer.
Compliance & Legal
Pay only for the layers you need. Start with C2PA, upgrade to invisible + quantum for advanced security.
