Security apparatus for computing systems
First Claim
1. A security apparatus, comprising:
- a transmitter configured to transmit acoustic signals in a computing system according to an acoustic pattern;
a receiver configured to receive returned acoustic signals in response to the transmitted acoustic signals;
a logic configured to;
upon receiving the returned acoustic signals at the receiver, generate acoustic measurements from the returned acoustic signals based on the acoustic pattern, the generated acoustic measurements relating to a physical arrangement of computing components within the computing system;
compare the generated acoustic measurements to baseline acoustic measurements, wherein the baseline acoustic measurements are derived from acoustic profiles corresponding to a default physical arrangement of computing components within the computing system; and
upon determining that the generated acoustic measurements do not substantially match the baseline acoustic measurements, assert a signal indicating that the default physical arrangement of computing components within the computing system has been altered.

Abstract
A security apparatus that can detect unauthorized alterations of physical arrangement of a computing system or unauthorized movements of a computing system through the use of acoustic signals is designed. Modules of a computing system including the security apparatus are able to generate acoustic measurements from received returned acoustic signals. Also, the modules are able to derive baseline acoustic measurements based on stored acoustic profiles. If, for any module of the computing system, its generated acoustic measurements do not substantially match its baseline acoustic measurements, the mismatch may indicate that there is an unauthorized alteration of physical arrangement of the computing system or an unauthorized movement of the computing system. Thus, the security apparatus in the module may take actions to prevent access to the sensitive data stored in the module.
