SECURELY AUTHENTICATING A RECORDING FILE FROM INITIAL COLLECTION THROUGH POST-PRODUCTION AND DISTRIBUTION

The technology disclosed relates to data captured in streams from sensors. Streams often are edited, especially video and audio data streams. In particular, the technology disclosed facilitates identification of segments of an originally captured stream that find their way into a finally edited stream and identification of changed segments in the finally edited stream. Summary analysis on self-aligned meta-blocks of stream data is described, along with pushing at least some self-aligned meta-hashes into a blockchain network, applying an alignment and hashing procedure described in a smart contract.
