Abstract:
A proof of provenance system receives database logs from an existing system that does not natively provide data provenance verification. The system produces a local representation of the database (or a portion thereof). The system periodically or in response to another triggering event flattens the local representation of the database to generate an aggregated slice, which is stored in an aggregated slice store. A reduced representation of the aggregated slice (e.g., a hash or checksum) is determined and appended to a distributed ledger, such as a blockchain. The provenance of data from the existing system can then be verified by redetermining the reduced representation and comparing it to the version appended to the distributed ledger.

Claim (Index 7):
The method of  claim 1 , wherein the distributed ledger is a blockchain.
