You asked"Protection is great, but how do I prove the work is mine?"
Shipped Early artists asked for proof of ownership, not just protection. Shipped, free, on every plan. Every image you protect now comes with a timestamped proof-of-ownership certificate: the cryptographic fingerprint of your original and protected files, countersigned by an independent timestamping authority, as a one-page PDF. The kind of evidence timestamping registries charge ~£30/year for, included. (Honest note on the certificate itself: copyright is automatic when you create a work; this is evidence to back your claim, not a government registration.)
ShippedAnyone can check a certificate.
Every certificate prints a public link, artvault.art/verify, where anyone (a buyer, a platform, a lawyer) can confirm we witnessed your work on the date shown. No account needed to verify.
You asked"Let me try it before I even make an account."
