  • Method and apparatus for enforcing tiered geographical anonymity in a mobile device
    Patent number: 9426776
    Abstract: A disclosed method of operation includes generating a first resolution geographic descriptor that identifies a first size geographic grid area. The first size geographic grid area includes a specific location identified by mobile device location data but does not identify the specific location. The method proceeds with adjusting the first resolution geographic descriptor to a second resolution geographic descriptor, by increasing or decreasing the resolution to correspondingly decrease or increase, respectively, the corresponding geographic grid area to a second size geographic grid area that includes the specific location. An information update is then sent to a server. The information update includes the second resolution geographic descriptor but does not provide the mobile device location data, in order to preserve the mobile device user's anonymity.
