Patent attributes
A system for restricting access to computer information accessible by a computer system. A computer system having access to computer information includes a detection circuit for receiving a wireless identification signal from a transmitting circuit of an identification object such as an identification badge. The identification signal includes identification information regarding the assigned possessor of the security object. In one embodiment, the detection circuit determines whether the assigned possessor of the security object as indicated by the wireless identification signal has authorized access to computer information accessible by the computer system. A user is given access if the identification information contained in the identification signal indicates that the assigned possessor is an authorized user. The computer system is placed in a condition to deny access to computer information accessible by the computer system in response to the identification signal detection circuit not having received for a predetermined period of time, a wireless identification signal containing identification information from an assigned possessor having authorized access.
