  • Patent number: 5896497
    Abstract: The present invention discloses a system and method for securing a computer. This system detects an event such as said number of key strokes or a mouse click. This systems reads for the presence or absence of an unprompted password prior to detecting the event. If the proper password is provided, the system is deactivated. If the appropriate password is not provided, a monitoring computer is notified of the unauthorized use of the protected computer. In notifying a monitoring computer, the system turns off the speaker of the modem so that the monitoring computer can be notified without alerting the unauthorized user. When the proper password is not provided, the system also notifies the monitoring computer so that the monitoring computer can check the unique identifying number of the protected computer. The location of that protected computer can then be traced.
