Abstract
An automatic identification system for communicating identifying information by coupling signals through the human body is provided. The system includes a battery powered identification device that transmits an identifying signal via a modulated carrier. The identification device is coupled to the body of the user via a coupling plate. The signal from the identification device is received by a reading device that is also coupled to the body of the user via a coupling plate. The reading device may display and/or enunciates the identifying information to the user. The coupling technique, carrier frequency, and construction of the devices are such that the identification information is not inadvertently radiated or coupled to unintentional users or receivers.

22. A method for using an automatic identification system to control a computer sign-on/sign-off system, the method comprising:
-
coupling an identification device to a user via one or more of a capacitive coupling and a galvanic connection using a coupling module; coupling a reading device to a computing device; transmitting identifying information from the identification device to the reading device via the user when the user establishes one or more of a capacitive coupling and a galvanic connection with the reading device; transmitting, by the reading device, the identifying information received from the identification device to the computing device; displaying a logon screen to the user if the identifying information received from reading device contains valid identifying information; logging on the user; monitoring keyboard activity using the computing device; disabling a display device of the computing device if the keyboard is inactive for a pre-determined amount of time; detecting keyboard activity using the computing device; checking the identifying information sent by the reading device; and enabling the display device of the computing device if the identifying information remains unchanged;
orlogging off the user if the identifying information received from the reading device has changed.
