Abstract
A system provides for a client to receive enhancement data without having personally identifiable information leave its systems. The system receives access to a client configuration and a data graph to perform configuration defined filtering and aggregation steps to produce a set of client files. These files contain a hashed version of PII from the data graph. They are then used by the client to match the identity of its population of objects to keys, the keys also being included in the set of client files. The client associates corresponding keys with objects in its own data graph, then requests enhancement data using only the keys. The data is returned using the matched keys without the use of personally identifiable information.
