PS analyzes logins using PS::GeoTracking technology. Each user is geographically profiled. Their exact location is derived from their IP address: City, Region, Country, and Coordinates (Latitude and Longitude). User logins are then mapped, and the distance between logins analyzed for any given user. If a login is mapped outside the acceptable radius threshold (measured in miles, and defined via Control Panel Preferences), the user is suspended. This algorithm ensures that false positives (false suspensions) and false negatives (failing to identify password sharing) are negligible.
