Tokenization of digital media files and associated derivatives

A computer-implemented method for managing digital media files in a computer network comprising:

• storing, in a memory of a processing server, a first digital media file, a set of derivative files and a logical association of the derivative files with the first digital media file;
• generating, via a first computer code module, a first cryptographic token;
• associating in the memory the first cryptographic token with the first digital media file;
• associating the first cryptographic token with a first wallet address corresponding to a first wallet;
• generating, via a second computer code module, a serialized set of non-fungible tokens and associating individual ones of the non-fungible tokens with individual ones of the derivative files;
• and
• associating individual ones of the non-fungible tokens with individual wallet addresses of a second set of wallets;
• wherein the first computer code module is configured to limit the initial transferability of the first cryptographic token from the first wallet to one of the second set of wallets.
