System and method for inhibiting access to a computer
First Claim
1. A computer security system for inhibiting access of an unauthorized user to a computer normally used by an authorized user at a workstation comprising:
- a. a sensor configured to collect sensory data about a region around said workstation, said sensory data indicating whether a person is present or absent in said region around said workstation, and transmit said sensory data to an electronic circuit;
b. a processing unit electronically connected to said electronic circuit, said processing unit configured to process said sensory data to determine whether a person is present in said region around said workstation; and
c. wherein said processing unit is further configured to send a command signal if said processing unit determines that no person is present in said region around said workstation for a period of time, said command signal configured to block access to said computer until said authorized user completes an authentication process with respect to said computer.

Abstract
A computer security system which prevents an unauthorized user from accessing the computer system when an authorized user has already logged onto the computer system and has temporarily left the workstation. The computer security system generally includes a sensor which is configured to detect the presence of a person in the region around a workstation and a processing unit which logs out of the computer when a person is no longer present in the region. An optional calibration tool may be provided to set the sensitivity of the sensor and prevent accidental logging out when the authorized user is still present in the region around the workstation.
