US Patent 11803864 Distributed ledgers for enhanced chain of custody certification

Aspects of the disclosure relate to enhanced chain of custody certification. A computing platform may establish, within a period of time of receiving data, a first distributed ledger that includes the data. The computing platform may receive a request to access the data. The computing platform may compute a first hash of the data indicating a state of the data prior to being accessed, and may record the first hash in a second distributed ledger. After granting data access, the computing platform may receive first information indicating actions performed on the data and second information indicating reasons for accessing the data. The computing platform may compute a second hash of the data indicating a state of the data after being accessed, and may record the second hash and the second information in the second distributed ledger. The computing platform may record, in a third distributed ledger, the first information.
