Embodiment Construction

[0055] refer to figure 1 A portable data storage device 10, in this example in the form of a mobile phone, includes a short-range wireless communication interface 12, in this example a transceiver chip in the form of a Bluetooth (RTM) chip. Although, the transceiver is visible on the bottom of the device, the transceiver is typically integrated in the device, or as an additional component integrated with or in the battery's housing of the device. The device 10 stores contact details and optionally appointments or other data locally on the device or in a SIM card provided with the device, and a processor in the device 10 in communication with the communication interface.

[0056]The backup device 20 has a short range wireless communication interface 22 in this example a transceiver chip in the form of a Bluetooth (RTM) chip. An optional internal or external antenna is provided on the board. The backup device includes a backup data storage 24, for example, a FLASH storage. Th...

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.

Description

technical field [0001] The present invention relates to the security of data stored in portable data storage devices, but does not exclude devices such as palmtop computers or PDAs or mobile phones, especially mobile phones. The invention also relates to the intrinsic security of portable data storage devices. Background technique [0002] In recent years, there has been a widespread increase in the use of small portable devices that store important data, such as contact and calendar information. Devices have become more user-friendly, smaller and more efficient increasing the number of applications for these devices and the effectiveness of these devices. The increased portability and power of these devices has many benefits, but has the disadvantage of being prone to misplacing or losing devices that contain large amounts of useful data. [0003] Having assessed the risk of loss or damage, many devices are equipped with backup functionality on other devices, such as desk...
