Abstract
Advertisers gather data about users and their mobile devices through ads placed within Android and iOS apps. Most of the time, location, device, and app information are linked to the same device using a unique advertising ID (Ad ID). If the Ad ID is not available, advertisers can still use geo-coordinates or IP address to infer links in data gathered from different ad placements.
