An intelligent security technology that can block access and even destroy data if a laptop is moved from its designated space was developed by Virtuity UK. Backstopp constantly monitors the electronic "heartbeat" of a laptop to determine its location. The software steps in to remove sensitive data If the laptop is moved from its allowed zone.

    The development, which is designed to be used in conjunction with encryption software, will allow easier access to data for authorised personnel whilst providing another layer of protection from data theft. The comprehensive system can provide an at-a-glance report of which laptops contain what data, and their level of security.

    Any wireless communication, such as WiFi, cand be utilized by Backstopp to locate laptops. The PCs can also be tagged with RFID chips to monitor movement when switched off - companies may wish to limit a laptop's movement to one desk, one floor or one building within a facility, for example.

    If a laptop owner reports it missing to the control centre, or the control centre concludes that the machine is "at risk", such as being moved through a stairwell, the system seeks out the digital heartbeat and sends the "self destruct" message. Meanwhile the software on the laptop can use any in-built webcam to start taking a series of photographs to help with identification of the culprit, uploading the images as soon as any network becomes available. The system is completely invisible to the thief.

    With prices starting at £10 a laptop per month, the new system is set to become an essential add-on security measure for companies and government departments. Data should continue to be encrypted in any case, says Virtuity, with BackStopp being used to bring a firm conclusion to any laptop loss.
