Proof of Origin for Digital Files
A cryptographic verification system for establishing when a digital file was first registered — without storing the file itself.

Cryptographic
SHA-256 fingerprint of the file.
Privacy
No file custody. Ever.
Timestamped
Registration evidence anchored in time.
Verifiable
Independent verification by anyone.
Built for verifiable digital provenance
VerixID computes a cryptographic fingerprint of a digital file, binds it to a timestamp, and signs the resulting registration record. The file itself never leaves your control.
Anyone can later verify that the same fingerprint was registered at that point in time — without needing the original file, the original registrar, or trust in a central authority.
