Protect your works — Seal Media
Seal your videos and your music before publishing them. Seal takes a fingerprint — image and sound together — and attaches it to your name, to a date, and to the places where you authorise publication. After that, anyone can check any copy, free and without an account.
Seal Media — sealing your works. US$10.00 one time (account setup, identity verification included), then US$49 per year, 50 sealings included. Checking a work stays free for everyone, forever.
