Abstract
Systems and methods for securing user location data are described. A method includes receiving, by a location server computer, an encrypted location from a mobile device. The encrypted location is a location of the mobile device encrypted with a public key. The method then includes receiving, by the location server computer, a location request message from an interaction processing server and partially decrypting, by the location server computer, the encrypted location with a first private key share to form a partially decrypted location. The method further includes transmitting, by the location server computer to the interaction processing server, a location response message with the encrypted location and the partially decrypted location. The interaction processing server then uses the partially decrypted location and the second private key share to form a decrypted location.
