1. A method, comprising:
obtaining, at a first computer system, an altered set of media data;
encoding into the altered set of media data, at the first computer system, metadata that indicates one or more alterations that were previously made to a set of media data, the one or more previously made alterations resulting in the altered set of media data;
creating, at the first computer system and after the metadata that indicates the one or more previously made alterations has been encoded into the altered set of media data, a cryptographic representation of at least a portion of the encoded and altered set of media data; and
outputting the cryptographic representation of at least the portion of the encoded and altered set of media data to an immutable ledger, wherein the cryptographic representation corresponds to an entry in the immutable ledger.
