A standard for proving authorship.
OriginMark exists for one reason: in a world where AI can generate anything in seconds and any file can be copied infinitely, creators need a credible way to prove they were first.
What we are
A cryptographic timestamping service that produces a portable, court-admissible certificate for any file. Backed by DigiCert (RFC 3161) and Bitcoin (OpenTimestamps). Works for text, images, code, music, blueprints — anything you can hash.
What we are not
We don't replace copyright registration (©), trademarks (™/®), or legal advice. We give you the strongest possible evidence of existence at a moment in time. Use it alongside formal IP registration where the stakes demand it.
Why a standard
Single-vendor solutions die. Standards endure. We're publishing our format as /.well-known/origimark.json — open spec, self-hostable, designed so verifiers can confirm certificates without ever calling our servers.
Who builds this
OriginMark is a project of the 5P group — a Slovenia-based publisher and creator-tech collective with operations across Europe. We build for ourselves first, then for everyone like us.
