Blockchain-based media content authentication methods and systems

A system for storing media authentication data using a distributed ledger, comprising:

• at least one processor of a computing node of a plurality of computing nodes configured to:
• receive one or more hashes associated with a media content and a timestamp associated with the media content, the plurality of computing nodes being communicatively linked;
• generate a data block that contains at least one of the received one or more hashes, the data block being generated by hashing a hash corresponding to a previous data block of the distributed ledger together with the at least one hash, the at least one hash corresponding to the media content of the data block being generated;
• and
• transmit a message reporting an addition of the generated data block to the distributed ledger, wherein at least some of the plurality of computing nodes maintain at least a partial copy of the distributed ledger.

A non-transitory computer readable medium storing thereon computer executable instructions for storing media authentication data using a distributed ledger, including instructions for:

• receiving one or more hashes associated with a media content and a timestamp associated with the media content, the plurality of computing nodes being communicatively linked;
• generating a data block that contains at least one of the received one or more hashes, the data block being generated by hashing a hash corresponding to a previous data block of the distributed ledger together with the at least one hash, the at least one hash corresponding to the media content of the data block being generated;
• and
• transmitting a message reporting an addition of the generated data block to the distributed ledger, wherein at least some of the plurality of computing nodes maintain at least a partial copy of the distributed ledger.
