Abstract
A system and method are provided for maintaining a historical record of anonymized user profile data for mobile device users. In one embodiment, a central system, which includes one or more servers, operates to obtain current locations and user profiles for users of mobile devices. The central system processes the current locations and the user profiles of the users over time to maintain a historical record of anonymized user profile data by location. By anonymizing the user data, privacy of the users of the mobile devices is maintained. The central system may then use the historical record of anonymized user profile data to respond to historical requests. The historical requests may be made by users of the mobile devices, subscribers, and/or third party services.
