Abstract
Described herein is a novel approach for coarse-grained user geolocation leveraging widely-deployed content delivery networks (CDNs). This method relies on the fact that CDN providers deploy a number of edge servers that are geographically distributed across the world. Many of these edge servers are assigned with unique identifiers that are tied to their location, which can be retrieved by inspecting HTTP responses headers served by these edge servers. As a result, a website can infer coarse-grained user location by asking a user to send an HTTP request to an arbitrary domain that is known being served by a CDN, and inspecting the corresponding responses.
