US Patent 11488571 Anti-eavesdrop security device

A system and method to prevent eavesdropping by a device. An anti-eavesdrop component is installed on the device. The anti-eavesdrop component is configured to actively prevent the device from capturing audio from the environment. In response to installing the anti-eavesdrop component, the device recognizes the anti-eavesdrop component as a primary audio input for the device. The anti-eavesdrop component then proceeds to block the device from capturing outside audio by injecting noise or otherwise interfering with the primary audio input.
