A system and method for analyzing media requests and evaluating the authenticity of geographic data associated with the media requests. A mobile device may use media requests to retrieve media items that are displayed to a user. A media request may include geographic data with latitude and longitude information and entity data identifying a user, application, mobile device, or combination thereof. The system may analyze the geographic data to identify locations and may analyze the entity information to identify user activity. The user activity may be internet activity of an application running on another device (e.g., user's desktop). The system may then correlate the user activity (e.g., accessing a venue web site) with the geographic locations (e.g., venue locations) to evaluate the authenticity of the geographic data associated with the mobile requests.
