Chain-of-custody of digital content in a database system

A method comprising:

• authorizing a blockchain for a video file;
• generating a first tracking value for an entry block of the blockchain referencing the video file, the first tracking value generated based on first data and the video file;
• receiving second data for each of additional blocks in the blockchain;
• generating second tracking values corresponding to each additional block based on the second data, the second tracking values identifying what processing was performed on the video file in each corresponding block of the additional blocks;
• forming the additional blocks including corresponding second tracking values;
• appending the additional blocks to the entry block, the entry block and the additional blocks linked in an ordered sequence, each of the additional blocks referencing a version of the video file that corresponds to an original version of the video file, as referenced by the entry block or a processed version of the video file that is based on sharing or changing an ownership of the video file or accessing or viewing the video file or a subsequent one of the additional blocks, the second data in each of the additional blocks indicative of processing performed on the version of the video file in that block,
• wherein the referenced version of the video file includes a sequential arrangement of video frames, metadata relating to corresponding ones of the video frames, and information that references a previous one of the video frames;
• and
• tracing through the blockchain based on the first tracking value and the second tracking values to confirm an auditable and immutable chain-of-custody of the video file.

A non-transitory computer-readable medium storing one or more instructions that when executed by a processor configure the processor to:

• authorize a blockchain for a video file;
• generate a first tracking value based on first data and the video file;
• form an entry block of the blockchain referencing the video file and the first tracking value;
• generate second tracking values corresponding to each additional block of the blockchain based on the second data, the second tracking values identifying what processing was performed on the video file in each corresponding block of the additional blocks;
• form the additional blocks including corresponding second tracking values;
• append the additional blocks to the entry block, the additional blocks linked in an ordered sequence, each of the additional blocks referencing a version of the video file that corresponds to an original version of the video file as set forth in the entry block or a processed version of the video file that is based on sharing or changing an ownership of the video file or accessing or viewing the video file by the entry block or a subsequent one of the additional blocks, the second data in each of the additional blocks indicative of processing performed on the version of the video file in that block,
• wherein the referenced version of the video file includes a sequential arrangement of video frames, metadata relating to corresponding ones of the video frames, and information that references a previous one of the video frames;
• and
• trace through the blockchain based on the first tracking value and the second tracking values to confirm an auditable and immutable chain-of-custody of the video file.
