1. A system for secure user authentication comprising:

  • a portable data storage device operably coupled with a host computing device, at least one of the portable data storage device or the host computing device being Bluetooth enabled, the portable data storage device comprising memory configured to store authentication information for access thereto, wherein the portable data storage device is a removable data storage device; and

    a portable Bluetooth enabled authentication device operable in a non-discoverable mode and configured to provide the authentication information to the portable data storage device via the host computing device for access to data stored on the portable data storage device through the host computing device, wherein the secure user authentication is required prior to access to the data stored on the portable data storage device;

    wherein access to the data stored on the portable data storage device is permitted via Bluetooth communication of the authentication information between the portable Bluetooth enabled authentication device and the at least one Bluetooth enabled portable data storage or host computing device, when the portable Bluetooth enabled authentication device is detected within a maximum Bluetooth range of the at least one Bluetooth enabled portable data storage or host computing device;

    wherein the portable Bluetooth enabled authentication device is able to receive and respond to Bluetooth requests while non-discoverable, wherein the portable Bluetooth enabled authentication device operates in the non-discoverable mode such that the portable Bluetooth enabled authentication device is not identifiable to other Bluetooth enabled devices performing discovery functions; and

    wherein the Bluetooth communication of the authentication information is performed with the portable Bluetooth enabled authentication device operating in the non-discoverable mode to establish the secure user authentication absent Bluetooth pairing between the portable Bluetooth enabled authentication device and the at least one Bluetooth enabled portable data storage or host computing device.
