A team of revolutionary scientists from the Austrian University of St. Pelten has released their SoniControl development for public access. This is an analogue of a firewall for working with a little-known communication channel between smartphones - ultrasonic tags.
Our gadgets always strive to eavesdrop on us, the reason for this is that the activation of the speaker and microphone is needed to transmit ultrasonic signals. The human ear cannot hear them, but for electronics it is analogous to Wi-Fi, NFC or Bluetooth. The OS on the smartphone uses them primarily as browser cookies, receiving and sending location information from surrounding devices, in order to then synchronize the data on the Internet.
Yes, we are being followed in another way, and the rejection of this fact prompted the authors of the SoniControl project to create an active protection system. It analyzes the operation of the smartphone's acoustic system to identify signs and algorithms for the operation of ultrasonic tags, and then generates interference. The sound is muffled by another sound still inaudible to the user. And in the next version of SoniControl there will be a function of selective jamming of signals for fine-tuning the system.
The SoniControl analogue is the SoniTalk project, which is focused on the Internet of Things. Various “smart devices” use ultrasound to “communicate” with each other, but the user is often not informed. In such an eco-environment, little depends on him at all, many do not even think to change the standard factory access password to their own, reliable one. To keep control of your devices and prevent third parties from hacking into this system, you need SoniTalk, the future standard in the field of ultrasonic communication with a clear and user-friendly interface.
