ABSTRACT:
The present invention relates to computerized theft and displacement control and observation, dedicated to objects which represent a certain value or importance for its owner and shall thus be observed. In particular, it relates to a wireless, particular Bluetooth-based method and system. A tight, customizable Bluetooth communication involving a positive feedback control signal from the Guardian to the observed device is established (210,220,230) reflecting the usual case. This status is left when the observed device leaves the reception area of the Guardian as the positive feedback signal misses (220,240). Then the observed device sends out (260) standardized “I am stolen” signals which can be received and evaluated fully automatically at multiple locations by respective Theft Monitors. Thus, respective measures can be undertaken to seize the device, e.g., by issuing a selective quiet alarm.
