Novel technologies like Silverpush build upon ultrasonic sounds to exchange information. More and more of our devices communicate via this inaudible communication channel. Ultrasonic communication enables to pair devices, exchange information but also to track users and their behavior across several devices similar to cookies in the web. 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.
SoniControl is the first firewall that detects ultrasonic activity, notifies the user and blocks the information on demand, and thereby helps users to protect their privacy.
