Embodiments define a method and apparatus for determining a geospatial location of an unlocated device communicatively coupled to a network while maintaining privacy. The unlocated device transmits a first encryption layer public enabling multiple other devices, including an assistant device, to employ the first encryption layer public key. The assistant device transmits a second encryption layer public key to the multiple other devices, and those devices return to the assistant device respective encrypted representations of geospatial locations encrypted by the first encryption layer public key and the second encryption layer public key. The assistant device decrypts the second layer encrypted representations of the geospatial locations with the second encryption layer secret key; and performs an averaging function on the representations of geospatial locations. The assistant device transmits the encrypted solution to the averaging function to the unlocated device, which decrypts the encrypted solution using the first encryption layer secret key.
