determining that the received second media content is authentic when a calculated hash of the at least one calculated hash is identical to at least one hash stored in the distributed ledger.
11. The method of claim 1 , wherein at least one hash of the received one or more hashes is generated by: receiving a media content to be analyzed and the timestamp associated with the media content; separating the received media content into one or more data streams or files containing at least one of: one or more frames, one or more segments, audio data, and metadata associated with the media content; and generating the at least one hash associated with the media content based upon the data streams or files.
12. The method of claim 11 , wherein the generating of the at least one hash further comprises:
transmitting the at least one hash to a computing node that is communicatively linked to a distributed ledger.
13. A system for storing media authentication data using a distributed ledger, comprising:
