File provenance database system

This invention describes a system for proving the origin and integrity of digital files, especially multimedia content. It works by breaking a file into pieces, generating random data for each piece, and then creating unique digital fingerprints (signatures) from both the file pieces and the random data. These fingerprints are then stored on a shared, unchangeable record called a blockchain, ensuring that any future changes to the file or its origin can be detected. The system specifically includes biometric authentication when the file is first created.
