Media attribution systems and methods

A media attribution system, the system comprising:

• a distributed ledger system comprising a plurality of nodes;
• a computing device configured to:
• receive a media data item, the media data item comprising media data and metadata;
• compute at least one metric based on the media data item;
• and
• transmit an attribution request comprising the at least one metric to at least one of the plurality of nodes;
• each of the plurality of nodes independently configured to:
• compute a respective attribution score in response to the attribution request and based on the at least one metric, wherein the computing the respective attribution score comprises processing the media data item using a machine learning system trained using a corpus of media data items;
• generate a respective attribution response comprising the respective attribution score, each respective attribution score of the plurality of nodes collectively forming a plurality of attribution responses;
• based on the plurality of attribution responses, compute a consensus attribution score based on the plurality of respective attribution scores in the plurality of attribution responses;
• and
• when the consensus attribution score exceeds a predetermined attribution score threshold, attribute the media data item to one or more rightsholder account in an attribution database.
