Abstract: Copies of a distributed ledger with multiple blocks are stored on multiple computing devices and a secure server that stores a plurality of authenticated digital media asset. A first computing device with an authenticated digital media asset generates a new block to the distributed ledger, and each subsequent computing devices with modifications made to the digital media asset adds a new block identifying modification made to the digital media asset and appends a hash of at least a portion of a previous block of the distributed ledger.
