1. A method, comprising:
receiving, at a first computer system, an altered set of media data that comprises a set of media data altered according to an alteration pattern, wherein metadata for the set of media data is encoded into the altered set of media data based at least in part on the alteration pattern;
creating a candidate cryptographic representation based at least in part on the altered set of media data;
receiving, at the first computer system, a trusted cryptographic representation of the altered set of media data, wherein the trusted cryptographic representation corresponds to an entry in an immutable ledger that is remote from the first computer system;
comparing the trusted cryptographic representation to the candidate cryptographic representation;
decoding the altered set of media data to obtain the metadata, the decoding based at least in part on the alteration pattern; and
presenting, by the first computer system, an indication of a level of validity for the altered set of media data based on least in part on the comparing.
