Abstract
The present invention is a method and system for providing a tamper alarm for a computer system. The method includes detecting tampering of the computer system, and transmitting electromagnetic field signals from a device concerning the tampering. In the preferred embodiment, the electromagnetic field signals are transmitted through patterns on a monitor or a video card which transmits a computer system identity information. The electromagnetic field signal of the present invention functions as a tamper alarm. When a receiver hears the alarm, the administrator of the computer system may act accordingly. The tamper evidence alarm may be transmitted in a manner which does not require the disabling of the computer system, thus increasing the ease of its use over conventional methods. Because the computer system is not disabled, a password is not required in order to regain access to the computer system. Also, the present invention may be practiced using existing hardware in the computer system, and thus is cost efficient to implement.
