Your work can be stolen.
Your proof cannot.

Content gets copied, claimed, and monetised by others every day. When an ownership dispute happens — in court, with a client, or on a platform — the person with a dated, verifiable record wins.

Without proof, your word against theirs is never enough.

If someone publishes your work before you can prove it, you lose — even if you created it first.

Ownership disputes are common Photographers, designers, and writers lose IP claims every year — not because they didn't create it, but because they couldn't prove when.
Registrations are slow and expensive Copyright offices take weeks. SBIX Certify creates immutable proof in seconds — for any file type, at a fraction of the cost.
A timestamp is the simplest proof A cryptographic record showing your file existed at a specific moment in time — before anyone else — is admissible evidence in EU courts.

How it works

2

We anchor the proof
