How it works

A certified creator fingerprints the final file of their work with this page and gives us only the fingerprint during their review.
We record it, with the title and date, on the creator’s public verification page.
Anyone can drop a file here: if its fingerprint matches, it is exactly the work that was certified. Change a single pixel, word or second of sound, and the fingerprint changes completely.

It checks original files. Social networks usually recompress images and videos, which changes their fingerprint. Use the original file: the one sold, sent, downloaded or submitted.
A fingerprint can’t be reversed. Nobody can rebuild a work from its fingerprint, which is why creators can share it safely.
A match proves identity, not more. It confirms the file is the certified work. What the certification covers is explained on the creator’s verification page.
