Abstract
Disclosed herein are systems and method for storing media authentication data using a distributed ledger. In one aspect, an exemplary method comprises, receiving, by a processor of a computing node of a plurality of computing nodes, one or more hashes associated with a media content and a timestamp, the computing nodes being communicatively linked, generating a data block that contains at least one of the received 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, transmitting to the plurality of computing nodes, a message reporting an addition of the generated data block, wherein at least some of the plurality of computing nodes maintain at least a partial copy of the distributed ledger.
