Content-based association of device to user
View Patent ↗Example methods and systems for content-based association of a device to a user are presented. In an example method, data corresponding to each of a plurality of items of content stored within a user device are accessed. A device identifier for the user device is generated based on the data. The device identifier is transmitted from the user device to a service device to associate the user device with a user.
