Systems and methods for preventing lightbeam access to microphones of smart devices

A method, comprising:

• detecting, via one or more sensors configured to couple to glass, a light signal embedded with an audio command;
• determining, via a controller, a frequency of the light signal;
• and
• disrupting, via the controller, the light signal by instructing a jammer to transmit a counter light signal having the frequency to interfere with the light signal such that activation of a smart device to perform an action based on an indication from a microphone of the smart device is inhibited.

A smart device, comprising:

• a microphone configured to receive an audio command;
• and
• a controller configured to:
• receive an indication of a light signal embedded with the audio command from one or more sensors;
• determine a frequency of the light signal in response to receiving the indication of the light signal;
• block the audio command from being received at the microphone of the smart device by instructing a jammer to transmit a counter light signal having the frequency to interfere with the light signal;
• determine a direction of a likely source of the light signal;
• and
• instruct a camera system to capture visual or audio data associated with the likely source.
