Abstract
An example operation may include one or more of authorizing a blockchain for a video file, generating a first tracking value for an entry block 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 based on the second data of the additional blocks, forming the additional blocks including the second tracking values, respectively, appending the additional blocks to the entry block, the entry block and the additional blocks cryptographically linked in an ordered sequence, each of the additional blocks referencing a version of the video file which corresponds to an original version of the video file as referenced by the entry block or a processed version of the video file, the second data in each of the additional blocks indicative of processing performed on the version of the video file in that block, and tracing through the blockchain based on the first and second tracking values to confirm an auditable and immutable chain-of-custody of the video file.
