Dynamic data difference generation and distribution

Abstract

A method of updating data may include receiving an update request from a computing device, the update request including a profile of a current set of data stored on the computing device; determining, based at least in part on the profile of the current set of data, an updated set of data is available; determining if a delta set of data has previously been generated to transform the current set of data to the updated set of data; and based on determining that the delta set of data has not been previously generated: generating the delta set of data; and transmitting an address, to the computing device, for obtaining the delta set of data by the computing device.
