Abstract: An acoustic filter mitigates audio signal-based attacks (particularly inaudible attacks in the ultrasonic frequency range) on voice-based computing devices by modulating the signals before they reach the device's microphone. One filter is formed as a rigid body defining multiple holes that exhibit local resonance phenomena that suppress incoming audio waves at specific frequencies. The filter distorts or otherwise modifies the attack signals and thereby prevents the microphone(s) from receiving the intended attack signal, and prevents the associated computing device from processing and executing the intended malicious “command”/signal. The filter can be tuned to be operable outside the frequency range of normal spoken commands, so that typical voice-based commands are unaffected by the filter. A frame is provided to enable one or more filters to be retrofitted to existing consumer electronics devices, outside their housings.
