System and method for preventing unauthorized access to restricted computer systems through the use of a wireless transmitter and receiver

An electronic based system for protecting a restricted access computer system from unauthorized access by automatically terminating access to the restricted access computer system which has been previously successfully logged onto by an authorized user when the authorized user leaves a vicinity of the restricted access computer system, said system comprising:

• an electronic access control system in communication with a restricted access computer system, said electronic access control system specifically programmed to control access to the restricted access computer system and allowing access only to the authorized user;
• an electronic access control file in communication with the electronic access control system, said electronic access control file containing information regarding authorized users for the restricted access computer system;
• a wireless receiver in communication with the electronic access control system,
• a wireless transmitter worn, carried or contained on the authorized user, the wireless transmitter separate from and not part of the restricted access computer system, the wireless transmitter transmitting a valid authentication signal;
• said wireless receiver in wireless communication with the wireless transmitter in order to receive the valid authentication signal transmitted by the wireless transmitter while the authorized user who has logged on to the restricted access computer system remains in the vicinity of the restricted access computer system;
• wherein after said restricted access computer system has been logged onto by an authorized user said electronic access control system programmed to determine if the valid authentication signal is being received by the wireless receiver from the wireless transmitter or whether a received authentication signal is above a signal strength threshold.
