Device, method, and system for secure mobile data storage

摘要

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.

主权项

1. A method for secure mobile data storage, the method comprising:
establishing, by a first mobile communication device, a wireless control link with a mobile data storage device using a short-range communication protocol, the wireless control link usable by the first mobile communication device to transmit control signals to the mobile data storage device; establishing, by the first mobile communication device, a first wireless data link with the mobile data storage device using a long-range communication protocol, the first wireless data link usable by the first mobile communication device to transfer data with the mobile data storage device in response to corresponding control signals transmitted to the mobile data storage device via the wireless control link; establishing, by the first mobile communication device, a second wireless data link with a second mobile communication device, the second wireless data link usable by the first mobile communication device to transfer data to the second communication device; receiving, by the first mobile communication device, a request for data from the second mobile communication device; transmitting, by the first mobile communication device, a control signal to the mobile data storage device using the wireless control link to request the data from the mobile data storage device; receiving, by the first mobile communication device, the requested data from the mobile data storage device using the first wireless data link; and transmitting, by the first mobile communication device, the received requested data to the second mobile communication device using the second wireless data link.
