Abstract
Media capture and verification originally-captured media files, the nature of modifications made to captured media files, and the authenticity of various versions of files related to the captured media are discussed. A computer identifies capture device output that represents an aspect of a recorded event. The computer cryptographically processes the capture device output to produce a validatable master file which includes master media data from the capture device output, master metadata of said master media data, and master file blockchain data. The master file blockchain data includes a master file block history portion, a master file signature key portion, a master file change indication portion, and a master file signed data hash portion. The computer also modifies the master media data to produce reference file media data. reference files and distributable files. The computer verifies the authenticity of each of these files.
