Abstract
Disclosed herein are systems and methods allowing provider server and an analytics server to communicate confidential information but not compromise the anonymity of the customers if the data transmitted in either direction were to be intercepted or otherwise viewed by an unauthorized party, each server is configured to transmit the data records of the customers without any personally identifying information (PII) associated with the customers. The databases may “link” the data records by separately generating customer key identifiers for each unique customer having data in the one or both of the databases, according to predefined parameters and a predetermined one-way hashing algorithm. The unique customer key identifier may then be concatenated to, appended to, or otherwise associated with each data record for a particular customer that is being communicated between the servers.
