Make your
ownership
machine-readable.
Platforms don’t send a person to check who owns a photo — they send a bot. SIGIL stamps every image and article you publish with a fingerprint and the exact rights metadata those bots read, so your authorship is recognised automatically.
Copyright is now enforced by software, at a scale no reviewer could match. If a crawler can’t read your claim in the file, it acts as if the claim isn’t there.
SIGIL writes your ownership into the places those systems actually look — embedded photo metadata, structured data, and a public registry record — so the answer to “who owns this?” is unambiguous and verifiable.
Four steps, one upload.
Everything below happens automatically the moment you publish a work — no plugins, no manual tagging.
Register
Each work gets a registry number and an immutable timestamp the instant you upload — your first claim on the record.
Fingerprint
We compute a SHA-256 of the exact file and a perceptual hash that survives resizing and re-compression, so re-uploads still trace back to you.
Mark
Your copyright, creator credit, licence and a link back to the registry are written into the image as IPTC + XMP — the fields platform bots read as “owner.”
Verify
A public, crawlable proof page exposes schema.org rights data and the provenance ledger, so any automated check resolves to you.
The claim travels with the work.
Download a registered image and the rights stay attached. Open it in any metadata viewer and you’ll see exactly what a crawler sees.
