ABSTRACT:
The personal computer security apparatus of the present invention provides a security architecture embedded within the personal computer itself to provide a practical level of security to thereby discourage theft of the personal computer. Apparatus are provided to monitor the continuity of the connection to the telephone line to which the personal computer is connected. Loss of voltage continuity on the telephone line for greater than a predetermined period of time is indicative of an individual unplugging the personal computer from the phone jack in order to enable the person to move the personal computer. Motion sensor switches are optionally provided to detect physical movement of the personal computer in excess of a predetermined minimum allowable range of motion. The apparatus generates an audible alarm in response to the detection of a person's attempt to relocate the personal computer without properly disabling the security software via the keyboard. In addition to the audible alarm that is generated, software resident on the personal computer can obliterate the data stored on the hard disk by reformatting the hard drive to thereby thwart a thief from having access to the data stored on the personal computer.
