Patent ID: 7548820

Claim:
A method for facilitating high-sensitivity detection of an anomaly in telemetry data from an electronic system using a telemetric impulsional response fingerprint of the telemetry data, the method comprising: applying a sudden impulse step change to one or more operational parameters of the electronic system during operation; generating a three-dimensional (3D) telemetric impulsional response fingerprint (TIRF) surface from a dynamic response in the telemetry data associated with the one or more operational parameters to the sudden impulse step change; and determining from the 3D TIRF surface whether the telemetry data contains an anomaly, which involves: generating a reference 3D TIRF surface for the 3D TIRF surface; computing a residual response surface between the 3D TIRF surface and the reference TIRF surface; and determining from the residual response surface whether the telemetry data contains an anomaly.
