Device, Method, and System for Secure Mobile Data Storage
First Claim
1. A mobile data storage device comprising:
- a first communication circuit to establish a wireless control link with a mobile communication device using a short-range communication protocol;
a second communication circuit, different from the first communication circuit, to establish a wireless data link with the mobile communication device using a long-range communication protocol;
a data storage to store data received from the mobile communication device; and
a processing circuit to (i) determine whether the mobile communication device is within a reference security range of the mobile data storage device as a function of the wireless control link and (ii) perform at least one security function on the mobile data storage device in response to the mobile communication device being out of the reference security communication range.

Abstract
A device, method, and system for secure mobile data storage includes a mobile data storage device having a short-range communication circuit, a long-range communication circuit, and a data storage for storing data. The mobile data storage device is used to store data used by a paired mobile communication device. The mobile data storage device and the mobile communication device communicate control signals over a wireless control link established using the short-range communication circuit and data over a wireless data link, different from the wireless control link, established using the long-range communication circuit. The mobile data storage device and/or mobile communication device may monitor a distance between the devices and perform a security function in response the devices being separated from each other. The mobile data storage device may backup data on a remote data server and/or repopulate data from the remote data server using the mobile communication device.
