A smart microphone that doesn't listen to you
PrivacyMic can filter out audible information right on the device it's on. That makes it more secure than encryption or other security measures that take steps to secure audio data after it’s recorded, or limit who has access to it. The system pieces together the ultrasonic information that’s all around us to identify when its services are needed, and sense what’s going on around it. Researchers have demonstrated that it can identify household and office activities with greater than 95% accuracy.
