Abstract: The disclosed embodiments relate to method and/or device which is effective at cancelling or altering electrical signals or pulses, generated by, for example, digital electronic systems and components, that are induced, reflected or otherwise made present on the mains power supply conductors and/or the earthing or grounding conductor (if present.) The disclosed embodiments cancel these electrical signals thereby providing an effective means of preventing the exfiltration of various data from a computing or similar system by means of power line emissions. The disclosed embodiments may perform this subjugation by: altering the shape of the fundamental current and voltage waveforms and also altering and diminishing any non-fundamental frequency waveforms to a point where they are no longer measurable or detectable; and preventing the communication via inductive coupling of any electrical signals on mains current onto the grounding path or vice versa.
