Abstract
Systems and methods of cryptographically protecting location data transferred between servers via a network to tune a location engine are described herein. A first encryption module determines a first hash value for each location determination, encrypts the first hash value for each location determination using a first encryption protocol to generate a first encrypted data set, and transmits the first encrypted data set to a server. The first encryption module receives, from the server, a second encrypted data set with second hash values generated by a second encryption module of the server using a second encryption protocol. The first encryption module creates a first double encrypted data set from the second encrypted data set. A tuner compares the first double encrypted data set with a second double encrypted data set received from the server to adjust the location engine.
