Abstract
A computer identifies capture device output that represents an aspect of a recorded event. The computer cryptographically processes the primary subsets of capture device output to produce a validatable master file which includes master file media data primary subset from the capture device output, master primary subset metadata of the master file media data primary subset, and master file blocktree data. The master file blocktree data includes a master file block history portion, a master file signature key portion, and a signed hash of the master file media data primary subset. The computer also modifies the master file media data primary subset to produce a reference file media data primary subset. reference files and distributable files. The computer verifies the authenticity of each of these files.
