Abstract

A technique for anonymizing location information of a mobile device includes intercepting, by the mobile device, a request for access to actual location information of the mobile device made by an application. The mobile device redirects the request to a trusted edge server. The trusted edge server obfuscates the location information based on a location of one or more other mobile devices proximal to the mobile device to generate obfuscated location information. The one or more other mobile devices are selected based on a similarity between a user profile associated with the mobile device and user profiles associated with the one or more other mobile devices. The trusted edge server returns the obfuscated location information to the mobile device, which sends the obfuscated location information to the application in place of the requested location information.
