Backstopp constantly keeps tabs on the electronic heartbeat of a laptop. If it detects that the laptop has been moved from its designated zone, Backstopp will step in to block access or even destroy data.
The software, which is designed to be used alongside encryption software, uses wireless communication such as WiFi to pinpoint the location of laptops. RFID chips can also be fitted to monitor movement when switched off.
If a laptop is reported missing or the control center concludes that the laptop is at risk because it has left its allowed area, then the system can send out a self destruct message. An in-built webcam on the laptop will then unobtrusively start taking photographs to help identify the thief. Cost is 10 pounds ($19.50) per laptop per month.
