First Claim
1. 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

Abstract
One embodiment of the present invention provides a system that facilitates high-sensitivity detection of an anomaly in telemetry data from an electronic system using a telemetric impulsional response fingerprint of the telemetry data. During operation, the system applies a sudden impulse step change to one or more operational parameters of the electronic system during operation. Next, the system generates a three-dimensional (3D) telemetric impulsional response fingerprint (TIRF) surface from a dynamic response in the telemetry data to the sudden impulse step change. The system then determines from the 3D TIRF surface whether the telemetry data contains an anomaly.
