System and techniques for digital data lineage verification

An apparatus, comprising:

• a memory comprising code to provide a graphical user interface;
• a display device;
• and
• a processor coupled with the memory and the display device, the processor to perform operations based upon execution of the code, the operations to:
• receive an original media file for storage in a media repository;
• apply an authentication hash function to the original media file including metadata to produce an original media file hash value, wherein the authentication hash function utilizes an authentication key;
• insert the original media file hash value in a message to be uploaded in a transaction to a blockchain platform;
• upload the transaction to the blockchain platform;
• and
• generate an indication in the graphical user interface that the transaction was successfully uploaded to the blockchain platform.

An apparatus, comprising:

• a memory comprising code;
• and
• a processor coupled with the memory the processor to perform operations based upon execution of the code, the operations to:
• receive a media file to be authenticated, wherein the media file is to be authenticated as unaltered and owned by a source of the media file;
• wherein the media file comprises intra-frames;
• generate a resulting hash value from the media file by applying a hash function of the received media file;
• cause a search of a blockchain platform for a transaction including an original media file hash that matches the resulting hash value generated from the media file;
• based on a result of the search, generate an indication that the media file is unaltered or owned by the source of the media file;
• extract intra-frames from the media file;
• apply the hash function to a respective extracted intra-frame to generate an intra-frame hash value for the respective extracted intra-frame;
• and
• insert the intra-frame hash value for the respective extracted intra-frame into a message to be uploaded with the original media file hash in the transaction.
