My goodness - I'd heard about trasmitting data using sound, but I also didn't realize its serious security implications.
From the repo description:
> SoniControl is a novel technology for the recognition and masking of acoustic tracking information. The technology helps end-users to protect their privacy.
> Technologies like Google Nearby and Silverpush build upon ultrasonic sounds to exchange information. More and more of our devices communicate via this inaudible communication channel. Every device with a microphone and a speaker is able to send and receive ultrasonic information. The user is usually not aware of this inaudible and hidden data transfer.
> To overcome this gap SoniControl detects ultrasonic activity, notifies the user and blocks the information on demand. Thereby, we want to raise the awareness for this novel technology.
Yeah, also consider there have been no studies to ensure that we aren't destroying our pet's hearing by using these sorts of frequencies. It depends on the dB, but dogs for example have a much longer hearing range and distance than humans.
