Data security device
First Claim
1. A method of safeguarding against loss of data stored in a primary portable data storage device, the method comprising providing a user-carried secondary backup device having memory and a wireless communication link for communicating with the primary portable data storage device;
- communicating periodically or quasi-continuously between the secondary backup device and the primary portable data storage device over the wireless communication link so as to automatically backup data entered into the portable data storage device and so as to check for removal of the primary portable data storage device;
signalling an alarm to alert a user to loss of the primary portable data storage device in the absence of communication between the primary portable data storage device and the backup device for a predetermined period.

Abstract
A method of safeguarding against loss of data stored in a portable data storage device or loss of the data storage device itself is described. A user-carried backup device having memory and a wireless communication link for communicating with the portable data storage device is provided. The backup device and the portable data storage device communicate periodically or quasi-continuously over the wireless communication link and may backup data entered into the portable data storage device and check for removal of the portable data storage device. An alarm is activated to alert a user to loss of the portable data storage device if the portable data storage device is out of range of communication for a predetermined period.

15. A method of safeguarding against loss of data stored in a portable data storage device, the method comprising providing a user-carried backup device having memory and a wireless communication link for communicating with the portable data storage device;
-
communicating periodically or quasi-continuously between the backup device and the portable data storage device over the wireless communication link at a selected one of a plurality of power levels to backup data entered into the portable data storage device and to check for removal of the portable data storage device;
signalling an alarm to alert a user to loss of the portable data storage device in the absence of communication between the portable data storage device and the backup device for a predetermined period;wherein communication initially operates at a first power level but switches to operating at a second power level if the portable data storage device does not pass out of range of communication with the backup device throughout a predetermined time period, wherein the second power level is lower than the first power level.
