Data security device
First Claim
1. A method of operating a portable data storage device having a short range wireless communication interface, the method comprising:
- preregistering a portable data storage device with a backup device in an authorization mode and then creating a secure pairing between the portable data storage device and the backup device to enable secure communication between the portable data storage device and the backup device over the wireless communication link, wherein the portable data storage device and the backup device are preregistered using a first key code and a secure pairing is created using a second key code;
communicating with the backup device over a wireless communication link using a short range wireless communication interface, wherein communicating with the backup device comprises communicating periodically or quasi-continuously between the backup device and the portable data storage device to monitor for separation of the backup device from the portable data storage device; and
initiating an alert procedure on separation of the backup device from the portable data storage device wherein the alert procedure comprises disabling at least one function of the portable data storage device.

Abstract
A portable data storage device is described, which includes a short range wireless communication interface. The device is configured to communicate with a backup device over a wireless communication link and further comprises an alerting device for initiating an alert procedure on separation of the backup device from the portable data storage device. The alert procedure may include one or more of: disabling at least one function of the portable data storage device, for rendering the portable data storage device at least partially inoperable in the absence of communication from the backup device, locking the portable data storage device, generating an audible, visible or vibrational signal, restricting access to certain functions of the portable data storage device, preventing use of the portable data storage device except to telephone a specified number to report the device as lost or to re-enable the device and/or communicating a unique identifier of the portable data storage device to a network.

7. A portable data storage device having a short range wireless communication interface and configured to communicate with a backup device over a wireless communication link, wherein communicating with the backup device comprises communicating periodically or quasi-continuously between the backup device and the portable data storage device to monitor for separation of the backup device from the portable data storage device, the device further comprising an alerting device for initiating an alert procedure on separation of the backup device from the portable data storage device, the device for initiating an alert procedure comprising an alerting device for disabling at least one function of the portable data storage device;
-
wherein the portable data storage device and the backup device preregister over the wireless communication link before a secure pairing is created between the portable data storage device and the backup device, and wherein the portable data storage device preregisters the backup device over the wireless communication link using a first key code and wherein the secure pairing is created using a second key code. - View Dependent Claims (8, 9, 10, 11, 12)
