A wireless security or managing system based on Bluetooth technology suited for a person on the move prohibits the use, without proper authentication, of electronic devices having special software installed. A watch, key holder or mobile telephone or other mobile electronic device equipped with a Bluetooth unit serves as a master in the everyday environment of a user, enabling access to slave devices such as laptop and desk computers, palm computers and PDAs and mobile telephones. Unless the ˜presence of the master device in the vicinity of a slave device is verified, the slave device automatically locks itself, switches itself or some import function off or enters a login state. |
