Technologies for auditing and maintaining access to protected data

A computer-implemented method of auditing access to a data service, the method comprising:

• receiving, by one or more processors, a data request to access requested data maintained by the data service, wherein:
• the data service is associated with a set of access restrictions using a private distributed ledger (i) maintained by a first plurality of node computers and (ii) controlling access to the data service and a public distributed ledger (a) maintained by a second plurality of node computers and (b) associated with a log of access to the data service, and
• the data request includes an indication of a requestor of the data request;
• after receiving the data request, updating, by the one or more processors, a smart contract transaction in the private distributed ledger, the smart contract transaction associated with the data request;
• transmitting, by the one or more processors, a fulfillment request to the data service, the fulfillment request configured to retrieve the requested data included in the data request;
• receiving, by the one or more processors, the requested data from the data service;
• providing, by the one or more processors, the requested data to a device associated with the requestor;
• determining, by the one or more processors, whether the data request complies with the set of access restrictions of the data service;
• updating, by the one or more processors, the smart contract transaction to indicate a status of the fulfillment request and the determination of whether the data request complies with the set of access restrictions;
• and
• in response to determining that the data request does not comply with the set of access restrictions, creating, by the one or more processors, a non-compliance transaction in the public distributed ledger.
