MarketSongs Proof

Proof of authorship, recorded at upload

MarketSongs Proof captures a verifiable snapshot of a work at the moment it is uploaded — timestamps, file fingerprints and the creator's declarations — and issues a public certificate.

What is MarketSongs Proof?

MarketSongs Proof is an authorship record generated for a listing. It bundles together objective signals (when the work was uploaded and its file hashes) with the creator's own rights and AI disclosures into a single certificate that anyone can verify.

Upload timestamp

The date and time the work was registered on MarketSongs.

File hashes

Cryptographic fingerprints of the uploaded files, so a file can be matched against the record later.

Creator rights declaration

The creator's signed statement that they own or control the rights needed to sell the work.

AI-assisted disclosure

Whether AI tools were involved, and the provider/model and rights status the creator declared.

Metadata snapshot

A frozen copy of the listing's key metadata at certification time.

Proof certificate

A certificate number and downloadable PDF you can share or archive.

Public certificate verification

Each certificate has a public verification page. Anyone with the certificate number can confirm it exists, see the recorded timestamp and declarations, and check that the listing carries a valid Proof badge.

What Proof does not guarantee

Proof records what was declared and uploaded — it does not independently adjudicate ownership disputes or verify the truth of a creator's declarations.

MarketSongs Proof records metadata, timestamps, hashes and creator declarations. It is not a government copyright registration and does not replace independent legal advice.
