Abstract: A method for establishing, confirming, and transferring ownership of digital artworks. The method associates a given artwork to a unique public ID and to an online service. The owner of the artwork is the person who has full access to the online service at the public ID. Confirming ownership of the artwork includes the owner performing an action that demonstrates the owner has full access to the online service at the public ID. Transferring ownership of the artwork includes (1) transferring access to the account itself, or (2) using the online service's transfer protocol, which may also update the public ID associated with the owner of the artwork.
