The result is a mathematical non-repudiable guarantee that the file under audit is exactly as recorded by the author. The authenticity of the author and the root of trust are provided by the notarizing trusted third-party. Integrity of the captured data is based on the time to insert its unique signature to the block-chain public ledger. This root of trust is intended to be permissible to prove authenticity of evidence in the legal arena (e.g., images of crime scenes, contracts, etc.) based on mathematical veracity.
