How Copyright Shield works
1
Fingerprint
HMAC-SHA256 creates a unique cryptographic hash of your file — any change to the file changes the hash.
2
Timestamp
RFC 3161 trusted timestamp records the exact moment of registration — court-admissible proof of when you created it.
3
Watermark
Invisible steganographic signature embeds your identity into the file itself — survives screenshots and re-uploads.
4
Certificate
Receive a PDF certificate + JSON manifest + permanent verification URL — ready for DMCA, legal, and platform submission.
