Abstract: Systems, methods and apparatus for authenticating a query device using a centralized data server include associating and storing, on the server, for each respective device in a plurality of devices, a device identifier, a user identifier, and a synthesized security identifier that collectively authenticate the respective user device. An authentication request is received, at the centralized server, from an intermediary gateway server seeking verification of the query device. The request has a query device identifier or a query synthesized security identifier. Verification, at the centralized data server, of the query device is done by searching for a match between the query device identifier and a stored device identifier and a match between the query synthesized security identifier and a stored synthesized security identifier. The centralized data server communicates to the intermediary gateway server whether the identity of the query device is verified.

Abstract: Systems, methods and apparatus for authenticating a query device by creating a synthesized security identifier include submitting, to a centralized data server, data associated with the query device. The data comprise information associated with a device identifier or a user identifier for the query device. The user identifier is not stored on the query device. The query device receives, from the centralized data server, a synthesized security identifier at least partially based on the data from the submitting step and stories the synthesized security identifier permanently on the query device. The query device further requests a remote user session by transmitting (i) the device identifier and (ii) the synthesized security identifier.
