Abstract
There is provided a personal device to be worn at the body of a user (), comprising an interface () for wireless data exchange with an external device (); at least one sensor () for sensing a parameter indicative of the proximity of the personal device () to the user; a loss detection unit () for determining, by regularly analyzing signals received from the sensor, whether the personal device is presently worn by the user or not; a control unit () for controlling operation of the personal device in a regular mode as long as the loss detection unit determines that the personal device is worn by the user and in a loss mode as long as the loss detection unit determines that the personal device is no longer worn by the user, wherein the wireless interface is directed to transmit in the regular mode a non-traceable device address and to transmit in the loss mode a traceable public device address.
