Embodiments may provide a physical device that may include two or more layers of integrated material that sits on top of the microphones of the voice-controllable devices and/or systems. The device may act as a physical barrier against the injected malicious laser beams while allowing sound waves reach the microphone for normal operation. For example, in an embodiment, an apparatus may comprise a first layer including at least one opening and a second layer including at least one opening, wherein the at least one opening in the first layer and the at least one opening in the second layer are arranged so as to block the passage of light, but to allow the passage of sound."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for defending against laser or other electromagnetic wave-based audio injection attacks on voice-controllable devices and systems","description":"Embodiments may provide techniques that protect voice-controllable devices and systems such that the microphone can be shielded from attacking modulated laser beams.
