Abstract
Systems and methods are disclosed for providing private location tracking. In general, a location-aware mobile device includes a location broker. Over time, as a location of the mobile device changes, the location broker generates a number of route fragments each defining the location of the mobile device over a corresponding period of time. The location broker obfuscates the route fragments and sends the obfuscated route fragments to a remote server for storage. At some point, the location broker receives a location tracking request from a requestor. In response, the location broker processes the location tracking request such that one or more obfuscated route fragments that are relevant to the location tracking request are obtained from the remote server and de-obfuscated to recover the corresponding route fragments. The recovered route fragments may then be utilized by the requestor.
